Abstract:
We re-assess exchange rate prediction using a wider set of models that have been proposed in the last decade: interest rate parity, productivity based models, and a composite specification. The performance of these models is compared against two reference specifications - purchasing power parity and the sticky price monetary model. The models are estimated in first-difference and error correction specifications, and model performance evaluated at forecast horizons of 1, 4 and 20 quarters, using the mean squared error, direction of change metrics, and the "consistency" test of Cheung and Chinn (1998). Overall, model/specification/currency combinations that work well in one period do not necessarily work well in another period.

Abstract:
We report findings from a survey of United States foreign exchange traders. Our results indicate that (i) technical trading best characterizes about 30% of traders, with this proportion rising from five years ago; (ii) news about macroeconomic variables is rapidly incorporated into exchange rates; (iii) the importance of individual macroeconomic variables shifts over time, although interest rates always appear to be important, and; (iv) economic fundamentals are perceived to be more important at longer horizons. The short run deviations of exchange rates from their fundamentals are attributed to excess speculation and institutional customer/hedge fund manipulation. Speculation is generally viewed positively, as enhancing market efficiency and liquidity, even though it exacerbates volatility. Central bank intervention does not appear to have a substantial effect, although there is general agreement that it increases volatility. Finally, traders do not view purchasing power parity as a useful concept, even though a significant proportion (40%) believe that it affects exchange rates at horizons of over six months.

Abstract:
We report findings from a survey of United States foreign exchange traders. Our results indicate that: (i) in recent years electronically-brokered transactions have risen substantially, mostly at the expense of traditional brokers; (ii) the market norm is an important determinant of interbank bid-ask spread and the most widely-cited reason for deviating from the conventional bid-ask spread is a thin/hectic market; (iii) half or more of market respondents believe that large players dominate in the dollar-pound and dollar-Swiss franc markets; (iv) technical trading best characterizes about 30% of traders, with this proportion rising from five years ago; (v) news about macroeconomic variables is rapidly incorporated into exchange rates; (vi) the importance of individual macroeconomic variables shifts over time, although interest rates always appear to be important; (vii) economic fundamentals are perceived to be more important at longer horizons, while short-run deviations from the fundamentals are attributed to excess speculation and institutional customer/hedge fund manipulation; (viii) speculation is generally viewed positively, as enhancing market efficiency and liquidity, even though it exacerbates volatility; (ix) central bank intervention does not appear to have substantial effect, although there is general agreement that it increases volatility, and finally; (x) traders do not view purchasing power parity as a useful concept, even though a significant proportion (40%) believe that it affects exchange rates at horizons of over six months.

Abstract:
We report findings from a survey of United States foreign exchange traders. Our results indicate that: (i) The share of customer business, versus interbank business, has remained fairly constant; (ii) The channels by which transactions take place have changed, as electronically-brokered transactions have risen from 2% to 46% of total, mostly at the expense of transactions undertaken by traditional brokers; (iii) The single most widely- cited reason for deviating from the standard market convention on the bid-ask spread is a thin/hectic market; (iv) Half or more of market respondents believe that large players dominate in the dollar-pound and dollar-Swiss franc markets; and (v) 60% of respondents believe there is low predictability of exchange rates intraday. Even at medium and long run horizons, only a third of traders believe that there is high predictability.

Abstract:
Standard economic models predict that the choice of an exchange rate regime has important implications for the interdependency of national monetary policies, which is sometimes measured by the degree of inflation transmission across borders. In this paper, we examine how inflation rates in two small open economies, namely Hong Kong and Singapore, interact with those in the U.S. It is found that the price levels in these three economies are cointegrated. Thus, a vector error correction model is used to study the inflation dynamics. It is found that Hong Kong and Singapore inflation rates, but not the U.S. one, respond to the error correction term. Compared with Singapore, the Hong Kong inflation rate is more responsive to U.S. price shocks. The different responses to U.S. price shocks are consistent with the difference in exchange rate regimes adopted by the two economies.

Abstract:
The status of real and financial integration of China, Hong Kong, and Taiwan is investigated using monthly data on one-month interbank rates, exchange rates, and prices. Specifically, the degree of integration is assessed based on the empirical validity of real interest parity, uncovered interest parity, and relative purchasing power parity. There is evidence these parity conditions tend to hold over longer periods, although they do not hold instantaneously. Overall, the magnitude of deviations from the parity conditions is shrinking over time. In particular, China and Hong Kong appear to have experienced significant increases in integration during the sample period. It is also found that exchange rate variability plays a major role in determining the variability of deviations from these parity conditions.

Abstract:
Previous assessments of nominal exchange rate determination have focused upon a narrow set of models typically of the 1970's vintage, including monetary and portfolio balance models. In this paper we re-assess the in-sample fit and out-of-sample prediction of a wider set of models that have been proposed in the last decade, namely interest rate parity, productivitybased models, and "behavioral equilibrium exchange rate" models. These models are compared against a benchmark model, the Dornbusch-Frankel sticky price monetary model. First, the parameter estimates of the models are compared against the theoretically predicted values. Second, we conduct an extensive out-of-sample forecasting exercise, using the last eight years of data to determine whether our in-sample conclusions hold up. We examine model performance at various forecast horizons (1 quarter, 4 quarters, 20 quarters) using differing metrics (mean squared error, direction of change), as well as the "consistency" test of Cheung and Chinn (1998). We find that no model fits the data particularly well, nor does any model consistently out-predict a random walk, even at long horizons. There is little correspondence between how well a model conforms to theoretical priors and how well the model performs in a prediction context. However, we do confirm previous findings that outperformance of a random walk is more likely at long horizons.

Abstract:
The study models the Hong Kong domestic exports and re-exports, compares the performance of exports to the rest of the world, the USA and Japan, and uses destination-and-export-type specific unit value indexes to construct real exchange rates. In general, Hong Kong exports display mean-reverting dynamics, are positively influenced by foreign income and are adversely affected by high value of its currency. The lagged export variable, foreign income, and real exchange rate provide most of the explanatory power. Other variables explain marginally the variability of Hong Kong exports.

Abstract:
The article examines the Hong Kong export performance. A standard export demand formulation is used as the benchmark. Then, we investigate the effects of real exchange rate volatility, "third" country competition, domestic wages, and costs of imports from China on export volume. The study models the Hong Kong domestic exports and re-exports separately, compares the performance of exports to the rest of the world, US and Japan, and uses destination-and-export-type specific unit value indexes to construct real exchange rates. It is found that Hong Kong export performance varies across export types and across destinations. In general, Hong Kong exports display mean-reverting dynamics, are positively influenced by foreign income, and are adversely affected by high value of its currency. The lagged export variable, foreign income, and real exchange rate provide most of the explanatory power. The other variables contribute only marginally in explaining the variability of Hong Kong exports.

Abstract:
Daily data from the German and U.S. equity markets before and after the introduction of the Euro are used to study the effect of exchange rate regime choices on equity markets. It is found that, since the introduction of the Euro, the volatility and the persistence of the German stock index have fallen significantly relative to those of the U.S. index. However, the switch in exchange rate arrangement appears to have no significant implication for the causal relationships - both the mean and variance causalities - between the two equity markets.

Abstract:
Advanced statistical techniques are used to analyze Hong Kong output dynamics. Hong Kong, Japan and the U.S. are found to share some common long-term and short-term cyclical variations. While the Hong Kong economy is susceptible to external shocks and Granger-caused by the other two economies, local factors account for a large proportion of output growth variability and are mainly responsible for her output uncertainty. On the transmission mechanism, the selected trade and financial variables have incremental explanatory power but do not lessen the ability of domestic and foreign output variables to explain Hong Kong growth dynamics. Interestingly, the U.S. does not appear to exert undue influences on Hong Kong.

Abstract:
The conventional view, as expounded by sticky-price models, is that price adjustment determines the PPP reversion rate. This study examines the mechanism by which PPP deviations are corrected. Nominal exchange rate adjustment, not price adjustment, is shown to be the key engine governing the speed of PPP convergence. Moreover, nominal exchange rates are found to converge much more slowly than prices. With the reversion being driven primarily by nominal exchange rates, real exchange rates also revert at a slower rate than prices, as identified by the PPP puzzle (Rogoff, 1996).

Abstract:
One argument for floating the Chinese renminbi (RMB) is to insulate China's monetary policy from the US effect. However, we note that both theoretical considerations and empirical results do not offer a definite answer on the link between exchange rate arrangement and policy dependence. We examine the empirical relevance of the argument by analyzing the interactions between the Chinese and US interest rates. Our empirical results, which appear robust to various assumptions of data persistence, suggest that the US effect on the Chinese interest rate is quite weak. Apparently, even with its de facto peg to the US dollar, China has alternative measures to retain its policy independence and de-link its interest rates from the US rate. In other words, the argument for a flexible RMB to insulate China's monetary policy from the US effect is not substantiated by the observed interest rate interactions.

Abstract:
This study suggests that some empirical findings against money-output causality can be the consequence of ignoring autoregressive conditional heteroskedastic (ARCH) errors. Monte Carlo results confirm that ARCH effects drastically reduce the power of the standard causality test. The maximum likelihood approach allowing for ARCH effects, on the other hand, provides a good power performance. Using different specifications and sample periods, Friedman and Kuttner (1993) and Thoma (1994) report limited evidence of money causing output. We detect significant ARCH effects in the models considered by these studies. Once ARCH effects are explicitly accounted for, we find that the monetary effect is significant though its magnitude is quite small.

Abstract:
This article presents a systematic and extensive empirical study on the presence of Markov switching dynamics in three dollar-based exchange rates. A Monte Carlo approach is adopted to circumvent the statistical inference problem inherent to the test of regime-switching behavior. Two data frequencies, two sample periods, and various specifications are considered. Quarterly data yield inconclusive evidence - the test rejects neither random walk nor Markov switching. Monthly data, on the other hand, offer unambiguous evidence of the presence of Markov switching dynamics. The results suggest that data frequency, in addition to sample size, is crucial for determining the number of regimes.

Abstract:
The study assesses the level of integration among the three Greater China economies (China, Hong Kong and Taiwan) and examines the suitability of a Greater China currency union. The three economies already have extensive trade and investment linkages. Our analyses show that they share common long-run and short-run cyclical variations. We also estimate the output costs of relinquishing policy autonomy to form a currency union. The estimated output losses, which depend on, e.g., the method used to generate shock estimates, seem to be moderate and are likely to be less than the efficient gains derived from a currency union.

Abstract:
This paper examines the implications for the Nordic countries (Denmark, Finland, Norway and Sweden) of participating in the final stage of the European Monetary Union. Economic linkages with Germany are estimated using a time series econometric approach under both the Bretton Woods and the post-Bretton Woods exchange rate regimes. Output responses of the Nordic countries to real and monetary disturbances emanating from Germany are estimated and compared with two small "core" EU members, Belgium and the Netherlands. We find that the long-standing EU members (Belgium, Denmark and the Netherlands) are closely integrated with Germany in that German shocks have a direct and large impact on their output developments. These linkages appear much weaker for Finland, Norway, and Sweden. Common European disturbances also do not distinguish the Nordic countries from the non-Nordic countries.

Abstract:
We evaluate whether the Renminbi (RMB) is misaligned, relying upon conventional statistical methods of inference. A framework built around the relationship between relative price and relative output levels is used. We find that, once sampling uncertainty and serial correlation are accounted for, there is little statistical evidence that the RMB is undervalued. The result is robust t various choices of country samples and sample periods, as well as to the inclusion of control variables.

Abstract:
A strand of exchange rate models postulate exchange rate fluctuations are driven by saddle-path dynamics and the related overshooting behavior. Using a bivariate system, the paper illustrates the relationship of the cointegration, saddle-path, and stationarity dynamics. Monte Carlo results indicate that the Johansen tests have reasonable power to discriminate saddle-path behavior from cointegration dynamics. Using monthly data from five major industrial countries, we find that exchange rates and prices are cointegrated. The cointegration result casts doubt on the use of saddle-path dynamics and the associated overshooting behavior to elucidate exchange rate variations.

Abstract:
We construct an empirical model for daily highs and daily lows of US stock indexes based on the intuition that highs and lows do not drift apart over time. Our empirical results show that daily highs and lows of three main US stock price indexes are cointegrated. Data on openings, closings, and trading volume are found to offer incremental explanatory power for variations in highs and lows within the VECM framework. With all these variables, the augmented VECM models explain 40% to 50% of variations in daily highs and lows. The generalized impulse response analysis shows that the responses of daily highs and daily lows to the shocks depend on whether data on openings, closings, and trading volume are included in the analysis.

Abstract:
Using data from 11 main manufacturing industries in 17 OECD countries, this paper empirically investigates the determinants of cross-country differences in the persistence of productivity differentials Specifically, we focus on the effects of product market structure and technology diffusion. It is found that the manufacturing industries display a wide range of convergence rates. Consistent with theories, the persistence of productivity differentials is found to be positively correlated with the price-cost margin and the intra-industry trade index - the proxies for market monopolistic behavior. The proxies for technology diffusion, however, do not exhibit consistently significant effect. Among the conditioning macro variables, productivity convergence appears to be enhanced by human capital but deterred by government spending.

Abstract:
We observe that daily highs and lows of stock prices do not diverge over time and, hence, adopt the cointegration concept and the related vector error correction model (VECM) to model the daily high, the daily low, and the associated daily range data. The in-sample results attest the importance of incorporating high-low interactions in modeling the range variable. In evaluating the out-of-sample forecast performance using both mean-squared forecast error and direction of change criteria, it is found that the VECM-based low and high forecasts offer some advantages over some alternative forecasts. The VECM-based range forecasts, on the other hand, do not always dominate - the forecast rankings depend on the choice of evaluation criterion and the variables being forecasted.

Abstract:
The linkages between the People's Republic of China and the other Chinese economies of Hong Kong and Taiwan are assessed, and compared against those with Japan and the US. We first characterize the time series behavior of three criteria of integration, namely real interest parity, uncovered interest parity, and relative purchasing power parity. There is evidence that these parity conditions tend to hold over longer periods between the People's Republic of China and all other economies, although they do not hold instantaneously. Overall, the magnitude of deviations from the parity conditions is shrinking over time. Amongst all, however, Hong Kong exhibits indications of a more advanced level of integration with the mainland. We also find that evidence is surprisingly positive for integration with the US. We then turn to examining the determinants of the degree of integration. Regression results suggest that the degrees of financial and integration depend upon the extent of capital controls, foreign direct investment linkages as well as exchange rate volatility.

The linkages between the People's Republic of China (PRC) and the other Chinese economies of Hong Kong and Taiwan are assessed, and compared against those with Japan and the US. We first characterize the time series behavior of variables corresponding to three criteria of integration, namely real interest parity, uncovered interest parity, and relative purchasing power parity. There is evidence that these parity conditions tend to hold over longer periods between the PRC and all other economies, although they do not hold instantaneously. In general, the magnitude of the deviations from the parity conditions is shrinking over time. Overall, however, Hong Kong exhibits indications of a more advanced level of integration with the PRC. We also find that evidence is surprisingly positive for integration with the US. We then turn to examining the determinants of the degree of integration. Regression results suggest that the degrees of financial and real integration depend upon the extent of capital controls, foreign direct investment linkages, as well as the magnitude of exchange rate volatility.

Abstract:
Previous findings of long-run purchasing power parity come mainly from data for industrial countries, raising the issue of whether the results suffer sample-selection bias and exaggerate the general relevance of parity reversion. This study uncovers substantial cross-country heterogeneity in the persistence of deviations from parity. The results show that it is more likely, rather than less likely, to find parity reversion for developing countries than industrial countries. Although some cross-country persistence variations may partly reflect country differences in structural characteristics such as inflation experience and government spending, a considerable portion of those variations appears unaccounted for.

Abstract:
Motivated by the observed international reserve hoarding behavior in the post-1997 crisis period, we explore the Mrs Machlup's Wardrobe hypothesis and the related keeping up with the Joneses argument. It is conceived that, in addition to psychological reasons, holding a relatively high level of international reserves reduces the vulnerability to speculative attacks and promotes growth. A stylized model is constructed to illustrate this type of hoarding behavior. The relevance of the keeping up with the Joneses effect is examined using a few plausible empirical specifications and data from 10 East Asian economies. Panel-based regression results are suggestive of the presence of the Joneses effect, especially in the post-1997 crisis period.

Abstract:
Previous assessments of forecasting performance of exchange rate models have focused upon a narrow set of models typically of the 1970's vintage. The canonical papers in this literature are by Meese and Rogoff (1983, 1988), who examined monetary and portfolio balance models. Succeeding works by Mark (1995) and Chinn and Meese (1995) focused on similar models. In this paper we re-assess exchange rate prediction using a wider set of models that have been proposed in the last decade: interest rate parity, productivity based models, and a composite specification incorporating the real interest differential, portfolio balance and nontradables price channels. The performance of these models is compared against two reference specifications - the purchasing power parity and the Dornbusch-Frankel sticky price monetary model. The models are estimated in error correction and first-difference specifications. Rather than estimating the cointegrating vector over the entire sample and treating it as part of the ex ante information set as is commonly done in the literature, we also update the cointegrating vector, thereby generating true ex ante forecasts. We examine model performance at various forecast horizons (1 quarter, 4 quarters, 20 quarters) using differing metrics (mean squared error, direction of change), as well as the consistency test of Cheung and Chinn (1998). No model consistently outperforms a random walk, by a mean squared error measure; however, along a direction-of-change dimension, certain structural models do outperform a random walk with statistical significance. Moreover, one finds that these forecasts are cointegrated with the actual values of exchange rates, although in a large number of cases, the elasticity of the forecasts with respect to the actual values is different from unity. Overall, model/specification/currency combinations that work well in one period will not necessarily work well in another period.

Abstract:
We examine the comovements between the output indexes of three German sectors (manufacturing, mining, and agriculture) and the three corresponding sectoral stock market indexes. It is found that data with and without seasonal adjustment give mixed results on the long-run interaction between the sectoral indexes. Compared with data that are non-seasonally adjusted, the adjusted data offer a weaker evidence on the cointegration relationship between a) the sectoral output indexes, b) sectoral stock indexes, and c) individual pairs of real and financial indexes. On short-run comovement, seasonally adjusted data offer stronger evidence on the presence of common synchronized and non-synchronized cyclical components.

Abstract:
This paper investigates output convergence for the G7 countries using multivariate time series techniques. We consider both the null hypotheses of no convergence and convergence. It is shown that inferences on output convergence depend on which one of the two null hypotheses is considered. Further, the no convergence results reported in previous studies using the time series definition may be attributed to the low power of the test procedures being used. Our results also highlight some potential problems on interpreting results from some typical multivariate unit root and stationarity tests.

Abstract:
The prospect of creating a currency union consisting of China, Japan, and Korea is evaluated using output data. After a brief discussion on the interactions between the three countries, the study investigates whether these three countries have common synchronous business cycles, which are perceived as one of the preconditions of a currency union. Then, we assess the potential costs of giving up monetary policy autonomy to form a currency union. It is found that the three national output series tend to move together in the long run and share common business cycles. While the output loss estimates depend on assumptions used to generate shocks, they tend to be small. However, there are potential conflicts between these countries on the choice of the policy target of the common monetary authorities.

We investigate the empirical determinants of China's outward direct investment (ODI). It is found that China's investments in developed and developing countries are driven by different sets of factors. Subject to the differences between developed and developing countries, there is evidence that a) both market seeking and resources seeking motives drive China's ODI, b) the Chinese exports to developing countries induce China's ODI, c) China's international reserves promote its ODI, and d) the Chinese capital tends to agglomerate among developed economies but diversify among developing economies. Similar results are obtained using alternative ODI data. We do not find substantial evidence that China invests in African and oil-producing countries mainly for their natural resources.

Abstract:
This study evaluates the individual roles of monetary and productivity shocks in real exchange rate fluctuations under the current float. Using a cointegration model of exchange rates and relative prices, the innovations are decomposed into transitory and common-trend parts. Both transitory and common-trend innovations are found to explain a significant portion of real exchange rate fluctuations, albeit their relative importance can vary across major currencies. Further analysis suggests that common-trend innovations are ascribed mostly to productivity shocks, whereas transitory innovations are governed by monetary shocks. The allowance for productivity shocks, however, appears insufficient to fully explain the high persistence of real exchange rates.

Abstract:
This study investigates whether greater nominal exchange rate flexibility aids real exchange rate adjustment based on data from dual exchange rates in developing countries. Specifically, we analyze whether the more flexible parallel market rate produces faster real exchange rate adjustment than the less flexible official rate does. Half-life estimates of adjustment speeds are obtained from fractional time series analysis. We find no systematic evidence that greater exchange rate flexibility tends to produce either faster or slower real exchange rate adjustment, albeit there is substantial cross-country heterogeneity in speed estimates. With official rates pegged to the dollar, many developing countries use parallel exchange markets as a back-door channel to facilitate real exchange rate adjustment. The evidence suggests, however, that these parallel markets often fail to speed up real rate adjustment.

Abstract:
Using annual data on nine manufacturing sectors of 18 OECD countries, the article studies the implications of market structure for cross-country relative price variability. It is found that, in accordance with predictions from a standard markup pricing model, reductions in market competition, along with increased nominal exchange rate volatility, are associated with greater variability of cross-country relative prices. The market structure also has similar effects on components of cross-country relative price variability. The empirical findings are robust to the inclusion of various control variables and alternative sample specifications.

Using a time series framework, the paper studies the interactions of the annual real per capita GDP data of the G7 countries. We find evidence of six common nonstationary processes behind the international output dynamics. In addition, there is evidence for the existence of a common business cycle among these countries. The trend and cycle components of each output series are obtained with a procedure that accounts for the presence of both the common nonstationary and cyclical factors. It is found that the relative variability and the correlation of the trend and cycle components are not similar across the G7 countries.

We find, first, that the Chinese currency, the renminbi (RMB), is substantially below the value predicted by estimates based upon a cross-country sample, when using the 2006 vintage of the World Development Indicators. The economic magnitude of the mis-alignment is substantial - on the order of 50 percent in log terms. However, the misalignment is typically not statistically significant, in the sense of being more than two standard errors away from the conditional mean. Moreover, this finding disappears completely when using the most recent 2008 vintage of data; then the estimated undervaluation is on the order of 10 percent. Second, we find that Chinese multilateral trade flows respond to relative prices - as represented by a trade weighted exchange rate - but the relationship is not always precisely estimated. In addition, the direction of the effects is sometimes different from what is expected a priori. For instance, Chinese ordinary imports actually rise in response to a RMB depreciation; however, Chinese exports appear to respond to RMB depreciation in the expected manner, as long as a supply variable is included. In that sense, Chinese trade is not exceptional. Furthermore, Chinese trade with the United States appears to behave in a standard manner - especially after the expansion in the Chinese manufacturing capital stock is accounted for. Thus, the China-US trade balance should respond to real exchange rate and relative income movements in the anticipated manner. However, in neither the case of multilateral nor bilateral trade flows should one expect quantitatively large effects arising from exchange rate changes. And, of course, these results are not informative with regard to the question of how a change in the RMB/USD exchange rate would affect the overall US trade deficit.

Abstract:
We use a class of stochastic volatility models with multiple latent factors to investigate the joint dynamics of return, trading volume, and open interest (a proxy for market depth) in currency futures markets. In accordance with theory, the empirical evidence indicates that there is more than one latent factor affecting these three variables. However, the evidence is ambivalent on the choice between two- and three-latent-factor models. These three variables also display different patterns of information spillovers across currency futures.

Abstract:
Using 25 years of monthly data on individual Japanese retail prices, we study the behavior of product-specific Law of One Price (LOP) deviations. Individual tradable products, compared with nontradables, are more likely to have different distributions of LOP deviations across cities. Their distributions are also more likely to change over time. Individual LOP deviation series are found to display considerable persistence and there is limited evidence that tradability enhances price convergence. In addition, deviations from the LOP are found to display nonlinear trends, and these trends are not linearly related to a product's tradability. For individual products, LOP deviations are affected by their own inflation rates and, to a lesser extent, by aggregate inflation, output variations, and monetary variability. Interestingly, the trend behavior remains significant in the presence of these economic variables.

Abstract:
This paper summarises the results of a survey of UK based foreign exchange dealers conducted in 1998. It addresses topics in three main areas: The microeconomic operation of the foreign exchange market; the beliefs of dealers regarding the importance, or otherwise, of macroeconomic fundamental factors in affecting exchange rates; microstructure factors in FX. We find that heterogeneity of traders' beliefs is evident from the results but that it is not possible to explain such disagreements in terms of institutional detail, rank or trading technique (e.g. technical analysts versus fundamentalists). As expected, non-fundamental factors are thought to dominate short horizon changes in exchange rates, but fundamentals are deemed important over much shorter horizons that the mainstream empirical literature would suggest. Finally, market norms' and behavioural phenomena are very strong in the FX market and appear to be key determinants of the bid-ask spread.

Abstract:
We examine the properties of the ASA-NBER forecasts for several US macroeconomic variables, specifically: (i) are the actual and forecast series integrated of the same order; (ii) are they cointegrated; and (iii) is the cointegrating vector consistent with long run unitary elasticity of expectations with respect to the actual series. We also examine whether forecasts respond to error correction terms. Tests are applied to both final and preliminary versions of the data. We find that the Treasury bill rate, housing starts, industrial production, inflation and their forecasts are trend stationary. The corporate bond rate, GNP, the GNP deflator, unemployment and their forecasts are difference stationary. About half of the these pairs are cointegrated, with the unitary elasticity restriction seldom rejected. Similar results are obtained when using the originally-reported data.

Abstract:
Engel and Rogers (1996) find that crossing the US-Canada border can considerably raise relative price volatility and that exchange rate fluctuations explain about one-third of the volatility increase. In re-evaluating the border effect, this study shows that cross-country heterogeneity in price volatility can lead to significant bias in measuring the border effect unless proper adjustment is made to correct it. The analysis explores the implication of symmetric sampling for border effect estimation. Moreover, using a direct decomposition method, two conditions governing the strength of the border effect are identified. In particular, the more dissimilar the price shocks are across countries, the greater the border effect will be. Decomposition estimates also suggest that exchange rate fluctuations actually account for a large majority of the border effect.

Abstract:
Using data from more than 100 economies for the period of 1975 to 2005, we conduct an extensive empirical analysis of the determinants of international reserve holdings. Four groups of determinants, namely, traditional macro variables, financial variables, institutional variables, and dummy variables that control for individual economies’ characteristics are considered. We find that the relationship between international reserves and their determinants is significantly different between developed and developing economies and is not stable over time. The estimation results indicate that, especially during the recent period, a developed economy tends to hold a lower level of international reserves than a developing one. Furthermore, there is only limited evidence that East Asian economies including China and Japan are accumulating an excessive amount of international reserves.

Abstract:
The debate on renminbi (RMB) revaluation has not subsided, despite the policy change announced by the Chinese authorities in July 2005. In this chapter, we show that the evidence of RMB undervaluation may not be as strong as it appears. Specifically, depending on the method used, the evidence ranges from slight overvaluation to undervaluation. Even in the case of undervaluation, the results are not significant in the statistical sense. We also note that China is playing an important economic role in Asia and has established a complex production and trade network with its neighboring economies, which complicates the calculation of the equilibrium exchange rate. Thus, a change in Chinese exchange rate policy in response to demands from foreign countries and short-run considerations may have undesirable effects on the economies of China and the Asian region.

Abstract:
We examine speculative attacks in a controlled laboratory environment featuring continuous time, size asymmetries, and varying amounts of public information. Attacks succeeded in 233 of 344 possible cases. When speculators have symmetric size and access to information: (a) weaker fundamentals increase the likelihood of successful speculative attacks and hasten their onset, and (b) contrary to some theory, success is enhanced by public access to information about either the net speculative position or the fundamentals. The presence of a larger speculator further enhances success, and experience with large speculators increases small speculators' response to the public information. However, giving the large speculator increased size or better information does not significantly strengthen his impact.

Abstract:
The paper studies the interactions between the U.S. and four East Asian markets. The focus is on the change in the information structure/flow between these markets triggered by the 1997 Asian financial crisis. It is shown that the information structure during the crisis period was different from that in the non-crisis periods. While the U.S. market led the four East Asian markets before, during, and after the crisis, it was Granger-caused by these markets during the financial crisis period but not in the postcrisis sample. Further, in accordance with concerns reported in the market, the Japanese currency is found to have affected these equity markets during the crisis period. The Japanese yen effect, however, disappeared in the post-crisis sample. The Japanese currency effect is quite robust as it is found from both local currency and U.S. dollar return data and in the presence of Japanese stock returns.

Abstract:
We study trade integration among 15 selected Asian and Oceanic economies using factor models. The principal component approach is employed to extract the common factor that drives trade integration from bilateral trade integration series. It is found that the estimated common trade integration factor has strong seasonal and deterministic components. In accordance with theory, the common trade integration factor is significantly associated with the economic growth and the trade barriers of the 15 economies. However, we find no evidence that the common trade integration factor is affected by foreign direct investment. The basic model is extended to incorporate an ASEAN factor that affects trade integration among the ASEAN economies in our sample.

Abstract:
We examine the empirical determinants of the demand for international reserves and compare the experiences of some Asian and Latin American economies. Our empirical results indicate that different vintages of the model of international reserves give different inferences about the appropriate level of international reserves. The developed and developing economies have equations of the demand for international reserves that are quite different from each other. Further, the Asian economies and the Latin American economies have different empirical determinants of the demand for international reserves. Our results highlight the complexity of evaluating whether an economy is holding an excessive or deficient level of international reserves - the inference can be heavily dependent on the choice of a benchmark model. A direct comparison affirms the perception that the Asian economies tend to hold more international reserves than the Latin American economies.

Abstract:
We investigate the empirical determinants of China’s outward direct investment (ODI). It is found that China’s investments in developed and developing countries are driven by different sets of factors. Subject to the differences between developed and developing countries, there is evidence that a) both market seeking and resources seeking motives drive China’s ODI, b) the Chinese exports to developing countries induce China’s ODI, c) China’s international reserves promote its ODI, and d) the Chinese capital tends to agglomerate among developed economies but diversify among developing economies. Similar results are obtained using alternative ODI data. We do not find substantial evidence that China invests in African and oil-producing countries mainly for their natural resources.

Abstract:
Arguably, international finance is one of the most exciting areas in economics. The development of international finance is influenced and shaped, at least in part, by the continuing process of globalization and integration. In the last 25 years the profession has witnessed the proliferation of both theoretical models and empirical analyses in international finance. The analysis of both new and existing issues has benefited from increasingly elaborate modelling techniques and sophisticated empirical tools.

Abstract:
This paper investigates output convergence for the G7 countries using panel time-series techniques. We consider both the null hypotheses of no convergence and convergence. It is shown that inferences on output convergence depend on which one of the two null hypotheses is considered. Further, the no convergence results reported in previous studies using the time-series definition may be attributed to the low power of the test procedures being used. Our results also highlight some potential problems on interpreting results from some typical panel unit root and stationarity tests.

Abstract:
Using available annual data of 174 economies since 1957, we examine the similarities and differences of seven international reserve ratios. While individual international reserve ratios display substantial variations across economies, they are associated with an economy's characteristics including geographic location, income level, stage of development, degree of indebtedness, and exchange rate regime. The association pattern varies across time and type of international reserve ratios. Interestingly, there is only limited evidence that Asian and non-Asian economies have significantly different international reserve hoarding behavior. Our results suggest that the inference about whether an economy is hoarding too many or too few international reserves depends on the choice of international reserve ratio. Further, different international reserve ratios exhibit different persistence profiles, but the evidence of dependence on structural characteristics is rather weak.

Abstract:
A more powerful version of the ADF test and a test that has trend stationarity as the null are applied to U.S. GNP. Simulated critical values generated from plausible trend and difference stationary models are used in order to minimize possible finite sample biases. The discriminatory power of the two tests is evaluated using alternative-specific rejection frequencies. For post-War quarterly data, these two tests do not provide a definite conclusion. However, when analyzing annual data over the 1869-1986 period, the unit root null is rejected, while the trend stationary null is not.

Abstract:
We examine the relationship between market structure and the persistence of U.S. dollar-based sectoral real exchange rates for fourteen OECD countries. Our empirical results based on disaggregated data suggest that differences in market structure significantly determine the rates at which deviations from sectoral purchasing power parity decay. Specifically, industries with a larger price-cost margin are found to exhibit slower parity reversion of their sectoral real exchange rates. Further, as the degree of intra-industry trade activity increases, sectoral real exchange rate persistence becomes more pronounced. These findings imply that an imperfectly competitive market structure contributes to the well-documented persistence in real exchange rates.

Abstract:
We evaluate whether the Renminbi (RMB) is misaligned, relying upon conventional statistical methods of inference. A framework built around the relationship between relative price and relative output levels is used. We find that, once sampling uncertainty and serial correlation are accounted for, there is little statistical evidence that the RMB is undervalued, even though the point estimates usually indicate economically significant misalignment. The result is robust to various choices of country samples and sample periods, as well as to the inclusion of control variables. We then update the results using the latest vintage of the data to demonstrate how fragile the results are. We find that whatever misalignment we detected in our previous work disappears in this data set.

Abstract:
This study investigates the sources of bilateral real exchange rate (RER) volatility in industrial countries. Going beyond traditional macroeconomic determinants, we identify the role of both trade and finance-related factors in explaining RER volatility at different time horizons. The results suggest that RER volatility tends to increase with financial openness and with transport costs but decrease with trade openness and with financial depth. Moreover, the time horizon matters. Financial factors (financial openness and financial depth) are found to influence RER volatility at primarily short horizons, while trade-related factors (trade openness and transport costs) contribute significantly also to RER volatility at much longer horizons. The relative importance of traditional macroeconomic fundamentals and these trade- and finance-related factors can vary considerably across horizons.

Abstract:
Exchange rate forecasts are generated using some popular monetary models of exchange rates in conjunction with several estimation techniques. We propose an alternative set of criteria for evaluating forecast rationality which entails the following requirements: the forecast and the actual series i) have the same order of integration, ii) are cointegrated, and iii) have a cointegrating vector consistent with long run unitary elasticity of expectations. When these conditions hold, we consider the forecasts to be consistent.' We find that it is fairly easy for the generated forecasts to pass the first requirement. However, according to the Johansen procedure, cointegration fails to hold the farther out the forecasts extend. At the one year ahead horizon, most series and their respective forecasts do not appear cointegrated. Of the cointegrated pairs, the restriction of unitary elasticity of forecasts with respect to actual appears not to be rejected in general. The exception to this pattern is in the case of the error correction models in the longer subsample. Using the Horvath-Watson procedure, which imposes a unitary coefficient restriction, we find fewer instances of consistency, but a relatively higher proportion of the identified cases of consistency are found at the longer horizons.

Abstract:
We introduce a time series model that captures both long memory and conditional heteroskedasticity and assess their ability to describe the US inflation data. Specifically, the model allows for long memory in the conditional mean formulation and uses a normal mixture GARCH process to characterize conditional heteroskedasticity. We find that the proposed model yields a good description of the salient features, including skewness and heteroskedasticity, of the US inflation data. Further, the performance of the proposed model compares quite favorably with, for example, ARMA and ARFIMA models with GARCH errors characterized by normal, symmetric and skewed Student-t distributions.

Abstract:
Aggregate Output is a focal point of macroeconomics. In the empirical literature, a number of variables are used as a proxy for aggregate output. In this paper, we compare the temporal behavior of four monthly measures of aggregate output: namely GDP, ICI, IP, and XCI. These four measures of output are found to have a common long-run permanent component but distinct short-run cyclical patters. The monetary effects on each of these four output variables are used to illustrate the implications of the choice of an output measure on empirical research. It is found that test results can be driven by the choice of the proxy for aggregate output.

Abstract:
This study assesses the claim that the Austrian economy depends mainly on the German business cycle. Controlling for possible influences from the U.S. economy, it is confirmed that the Austrian and German industrial production indexes have a common long-term stochastic trend and the German industrial production Granger causes the Austrian one in the short run. However, German and U.S. shocks only account for a small proportion of Austrian industrial production variability. Further, it is found that the three countries share a non-synchronized common business cycle.
