Abstract:
Mexico, a prominent liberalizer, failed to attain stellar gross domestic product (GDP) growth in the 1990s, and since 2001 its GDP and exports have stagnated. In this paper we argue that the lack of spectacular growth in Mexico cannot be blamed on either the North American Free Trade Agreement (NAFTA) or the other reforms that were implemented, but on the lack of further judicial and structural reform after 1995. In fact, the benefits of liberalization can be seen in the extraordinary growth of exports and foreign domestic investment (FDI). The key to the Mexican puzzle lies in Mexico's response to crisis: a deterioration in contract enforceability and an increase in nonperforming loans. As a result, the credit crunch in Mexico has been far deeper and far more protracted than in the typical developing country. The credit crunch has hit the nontradables sector especially hard and has generated bottlenecks, which have blocked growth in the tradables sector and have contributed to the recent fall in exports.

Abstract:
There is no agreement regarding the growth-enhancing effects of financial liberalization, mainly because it is associated with risky international bank flows, lending booms, and crises. In this paper we make the case for liberalization despite the occurrence of crises. We show that in developing countries trade liberalization has typically been followed by financial liberalization, which has indeed led to financial fragility and a greater incidence of crises. However, financial liberalization also has led to higher GDP growth. In fact, the fastestgrowing countries are typically those that have experienced boom-bust cycles. That is, there is a positive link between GDP growth and the bumpiness of credit, which is captured by the negative skewness - not by the variance - of credit growth. To substantiate our interpretation of the data we present a model that shows why in countries with severe credit market imperfections, liberalization leads to higher growth and, as a byproduct, to financial fragility. Thus, occasional crises need not forestall growth and may even be a necessary component of a developing country's growth experience. Finally, our analysis indicates that foreign direct investment does not obviate the need for risky international bank flows, as the latter are the only source of financing for most firms in the nontradables sector.

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.

Exchange Rate Regime, Market Volatility, Stock Market Interaction

Abstract:
This paper reconsiders the determinants of the exchange rate by studying the historical episode after the fall of the Iron Curtain. Testing a modified portfolio balance model, we attribute the strength of the deutschmark in the early nineties and the puzzling decline of the euro during its virtual existence to changes in the demand for deutschmarks in eastern Europe and to variations in the demand for black money balances in Europe as a whole. We reject the view that the strength of the dollar and the weakness of the euro reflect the prosperity of the US and the weakness of the European economy on both theoretical and empirical grounds.

Abstract:
The analogy between the economic problems of the Mezzogiorno region and East Germany has been initially contested by many authors. This paper argues that there are striking similarities in the two regions, in terms of the causes of their economic predicament. With an aggregate labour productivity of 55% relative to the rest of the country, both are true transfer economies, whose consumption exceeds production by far. Beyond locational disadvantages, the present paper identifies overdrawn wages, high social security spending and the Dutch disease problem as core reasons for the poor economic performance and discusses possible cures.

The analogy between the economic problems of the Mezzogiorno region and East Germany has been initially contested by many authors. This paper argues that there are striking similarities in the two regions, in terms of the causes of their economic predicament. With an aggregate labour productivity of less than 60% relative to the rest of the country, both are true transfer economies, whose consumption exceeds production by far. Beyond locational disadvantages, the present paper identifies overdrawn wages, high social security spending and the Dutch disease problem as core reasons for the poor economic performance and discusses possible cures.

Abstract:
We address the question of whether growth and welfare can be higher in crisis prone economies. First, we show that there is a robust empirical link between per-capita GDP growth and negative skewness of credit growth across countries with active financial markets. That is, countries that have experienced occasional crises have grown on average faster than countries with smooth credit conditions. We then present a two-sector endogenous growth model in which financial crises can occur, and analyze the relationship between financial fragility and growth. The underlying credit market imperfections generate borrowing constraints, bottlenecks and low growth. We show that under certain conditions endogenous real exchange rate risk arises and firms find it optimal to take on credit risk in the form of currency mismatch. Along such a risky path average growth is higher, but self-fulfilling crises occur occasionally. Furthermore, we establish conditions under which the adoption of credit risk is welfare improving and brings the allocation nearer to the Pareto optimal level. The design of the model is motivated by several features of recent crises: credit risk in the form of foreign currency denominated debt; costly crises that generate firesales and widespread bankruptcies; and asymmetric sectorial responses, where the nontradables sector falls more than the tradables sector in the wake of crises.

Abstract:
In this paper, we document the fact that countries that have experienced occasional financial crises have on average grown faster than countries with stable financial conditions. We measure the incidence of crisis with the skewness of credit growth, and find that it has a robust negative effect on GDP growth. This link coexists with the negative link between variance and growth typically found in the literature. To explain the link between crises and growth we present a model where weak institutions lead to severe financial constraints and low growth. Financial liberalization policies that facilitate risk-taking increase leverage and investment. This leads to higher growth, but also to a greater incidence of crises. Conditions are established under which the costs of crises are outweighed by the benefits of higher growth.

Abstract:
With inflation under control in many middle-income countries (MICs), it is now swings in credit, investment and asset prices that affect these countries the most. In this paper we present a framework to analyze both theoretically and empirically how credit market shocks are propagated and amplified in MICs. The strength of the credit channel in our model derives from two key characteristics of MICs: (i) a sharp asymmetry across the tradables (T) sector and the more bank-dependent nontradables (N) sector; and (ii) a significant degree of currency mismatch in the N-sector. This makes movements in the real exchange rate the driving element in the amplification of shocks. The equilibrium imposes unambiguous contemporaneous linkages among key macroeconomic variables and allows us to derive structural VARs. Estimating these VARs using quarterly data for a group of MICs, we find evidence for a strong credit channel, for a balance sheet effect and for asymmetric sectorial responses. Our findings indicate that inflation targeting is not sufficient to guarantee economic stability, as such policy might overlook the development of lending booms and associated sectorial asymmetries

Abstract:
Credit market conditions play a key role in propagating shocks in middle income countries (MICs). In particular, shocks to the spread between domestic and international interest rates have a strong effect on GDP, and an even stronger effect on domestic credit. This strong credit channel is associated with a sharp sectorial asymmetry: the output of the bank-dependent nontradables (N) sector reacts more strongly than tradables (T) output. This asymmetry, in turn, is associated with a strong reaction of the real exchange rate - the relative price between N and T goods. We present a model that reconciles these facts and leads to a well specified estimation framework. From the equilibrium we derive structural VARs that allow us to identify shocks to credit market conditions and trace their effects on the economy. We estimate these structural VARs for a group of MICs and find evidence of a strong credit channel. We argue that at the heart of the MIC credit channel are a deep asymmetry in financing opportunities across N and T sectors, and a severe currency mismatch. This makes movements in the real exchange rate the driving element in the amplification of shocks. Finally, we show that the model's key assumptions are consistent with evidence gleaned from both firm level and aggregate data.

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:
Factor price equality across countries is an important implication of the Heckscher-Ohlin-Samuelson model of international trade. Although an influential theoretical result, the model has received surprisingly little empirical support. Burgman and Geppert (1993) argue that this might be due to the neglect of the non-stationarity property of the time series under consideration. Using a cointegration approach, they find strong evidence pointing towards a long-run relationship between factor prices in six major industrialized countries. The present paper shows, however, that there is only limited evidence of cointegration once the finite sample bias is taken into account. Moreover, there is only weak evidence of a significant cointegrating relationship when real (rather than nominal) labor cost data are used. There is some indication of long-run co-movements of real factor prices when using the statistically more powerful bivariate tests rather than a multivariate framework.

Abstract:
In this paper we characterize empirically the comovements of macro variables typically observed in middle income countries, as well as the "boom-bust cycle" that has been observed during the last two decades. We find that many countries that have liberalized their financial markets, have witnessed the development of lending booms. Most of the time the boom gradually decelerates. But sometimes the boom ends in twin currency and banking crises, and is followed by a protracted credit crunch that outlives a short-lived recession. We also find that during lending booms there is a real appreciation and the nontradables (N) sector grows faster than the tradables (T) sector. Meanwhile, the opposite is true in the aftermath of crisis. We argue that these comovements are generated by the interaction of two characteristics of financing typical of middle income countries: risky currency mismatch and asymmetric financing opportunities across the N- and T-sectors.

Abstract:
In this paper we document three credit market imperfections prevalent in middle income countries that can help to explain boom-bust cycles, as well as other macroeconomic patterns observed at higher frequencies across these countries. These imperfections are: the existence of financing constraints that affect mainly the nontradables sector, currency mismatch and guarantees that cover lenders against systemic crises. In MICs T-sector firms have access to international capital markets, while most N-firms are bank-dependent and are financially constrained. Systemic guarantees generate incentives for borrowers to take on insolvency risk by denominating debt in foreign currency. This currency mismatch makes movements in the real exchange rate - the relative price between N and T goods - the driving element in the amplification of shocks.

Abstract:
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.

Abstract:
We present a unified treatment of optimal trade policy for a small country. The well-known results for duopoly and competitive markets emerge as benchmark cases of our model. In addition, we show that changes in market structure have non-monotonic effects on optimal tariffs. Our results suggest that the recent reduction of tariffs in Eastern Europe is consistent with welfare maximizing trade policy in response to the substantial changes in the market structure of these countries.

In this paper we re-investigate the comovements of interest rates in the G7-countries. We propose a structured modus operandi to analyze the time series characteristics of interest rates and to test for common features. We conduct cointegration, serial correlation common feature and codependence tests with nominal and real interest rates using quarterly data from 1975 to 2007. Overall we only find little evidence of comovements. Common trends are occasionally observed, but the majority of interest rates are not cointegrated. Although some evidence for codependence of higher order is found among European countries, common cycles appear to exist only in rare cases and cannot be generalized for all interest rates.

Abstract:
We present a new empirical decomposition of the effects of financial liberalization on economic growth and on the incidence of crises. Our empirical estimates show that the direct effect of financial liberalization on growth by far outweighs the indirect effect via a higher propensity to crisis. We also discuss several models of financial liberalization and growth whose predictions are consistent with our empirical findings.

Abstract:
In a homogeneous-good duopoly game with a home and a foreign firm, which compete on prices, it has been shown that the optimal way to assist the domestic industry is by a production subsidy. The argument here is that the subsidy is used to keep potential competitive pressure on the foreign firm. This paper analyzes under which conditions this threat of entry of a subsidized home firm is credible. It is shown that in markets where the firms move before the government, a subsidy is not credible and dominated by a tariff in terms of welfare.

Abstract:
The paper empirically investigates international productivity convergence in the manufacturing sector, which was found not converging in earlier studies. The authors analyze subsectors of aggregate manufacturing in order to compare similar technologies and to avoid the mixing of converging and nonconverging subsectors in the aggregate. Some of the subsectors converge while others, as well as aggregate manufacturing, do not. There is stronger evidence of convergence in subsectors with a smaller number of different industries. The latter serves as a proxy for the variety of technologies. Overall, the results highlight the importance of comparing similar technologies when studying productivity convergence.

Abstract:
We evaluate the proposal for official dollarization in Costa Rica by applying a new approach to measure the business cycle comovements with the United States. While the literature often focuses on the correlation of shocks, we point out that the response of each country to the shocks is also an important aspect of stabilization policy. We analyze whether Costa Rica and the United States share a common synchronized response to shocks, i.e. a common business cycle, using the Engle and Kozicki (1993) and Cubadda (1999, 2007) serial correlation common features tests, in a quarterly GDP data set from 1991 to 2008. Although we find some tendency towards common AR(p) structures and common long run trends, we reject the hypothesis that the two countries share a common business cycle. Based on this evidence, we conclude that official dollarization in Costa Rica would impede the efforts of its stabilization policy, despite the relatively high contemporaneous correlation of shocks.

Abstract:
This paper investigates productivity convergence in the Manufacturing sector for a set of European countries using a time series framework. We apply a panel data unit root test (PDUR) to total factor productivity (TFP) differentials, where the null hypothesis--the presence of a unit root or a deterministic component--can be interpreted as no convergence. Earlier studies have consistently found the Manufacturing sector non-converging. Our empirical analysis reveals more evidence of convergence as higher levels of disaggregation are explored. We suggest product heterogeneity as a major source for the negative findings of convergence at the aggregate level.

Abstract:
Developing and Eastern European countries recently started opening their economies. We analyze how the opening to international trade can be accompanied by strategic trade policy if the resulting market structure is oligopolistic. We find that for reasonable parameter values, a tariff is the optimal policy tool. Furthermore, tariffs and quotas are not welfare equivalent in our model.
