Abstract:
This paper discusses links between policy settings, institutions and economic growth in OECD countries on the basis of cross-country time-series regressions. The econometric approach allows short-term adjustments and convergence speeds to vary across countries, imposing restrictions only on the long-run coefficients. In addition to the 'primary' influences of capital accumulation and skills embodied in the human capital, the results confirm the importance for growth of R&D activity, the macroeconomic environment, trade openness and well developed financial markets. They also confirm that many of the policy influences operate not only 'directly' on growth but also indirectly via the mobilisation of resources for fixed investment. The paper also reports some bivariate correlations between OECD indicators of product regulation and growth. They provide some supporting evidence that the negative impact of stringent regulations and administrative burden on the efficiency of product markets also results in a negative impact on overall economic growth.

Abstract:
This paper presents empirical estimates of human-capital augmented growth equations for a panel of 21 OECD countries over the period 1971-98. It uses an improved dataset on human capital and a novel econometric technique that reconciles growth model assumptions with the needs of panel data regressions. Unlike several previous studies, our results point to a positive and significant impact of human capital accumulation to output per capita growth. The estimated long-run effect on output of one additional year of education (about 6 percent) is also consistent with microeconomic evidence on the private returns to schooling. We also found a significant growth effect from the accumulation of physical capital and a speed of convergence to the steady state of around 15 percent per year. Taken together these results are not consistent with the human capital augmented version of the Solow model, but rather they support an endogenous growth model a la Uzawa-Lucas, with constant returns to scale to "broad" (human and physical) capital.

Abstract:
In this paper we present an international comparison of growth trends in the OECD countries, with a special attention to developments in labour productivity - allowing for human capital accumulation - and multifactor productivity (MFP) - allowing for changes in the composition of fixed capital. An attempt is also made to identify both the embodied (in particular in ICT equipment) and disembodied components of technical progress. The possible relation between improvements in MFP and the accumulation of knowledge (as proxied by R&D expenditures) is discussed, and some tentative policy considerations are advanced, mainly with reference to general framework conditions that might have a bearing in fostering technological changes.

The main conclusions are that some "traditional" factors lay behind the disparities in growth patterns across the OECD countries. In particular, they refer to the ability of countries to employ their labour force. There also seem to be some new factors behind growth performance, especially in connection with the diffusion of ICT and related increases in MFP growth rates in the United States. However, it is too early to say whether, even in the United States, the more recent pick-up in the (disembodied) component of MFP may also be related to the presence of spillover and network effects.

Abstract:
This paper discusses growth performance in the OECD countries over the past two decades. Special attention is given to developments in labour productivity, allowing for human capital accumulation, and multifactor productivity (MFP), allowing for changes in the composition and quality of physical capital. The paper suggests wide (and growing) disparities in GDP per capita growth, while differences in labour productivity have remained broadly stable. These patterns are explained by different employment growth rates across countries. In the most recent years, a rise in MFP growth in ICT-related industries has boosted aggregate growth in some countries (e.g. the United States).

Abstract:
This paper reviews the existing evidence on workplace training in Europe in different data sources - the CVTS, OECD data and the European Community Household Panel. We outline the differences in training incidence and relate these differences to the private costs and benefits of training, and to institutional factors such as unions, employment protection and product market competition. We ask whether there is a case for under-provision of training in Europe and examine alternative policies aiming both at raising training incidence and at reducing inequalities in the provision of skills.

Abstract:
This paper analyses several of the cross-market effects of policies aimed at influencing outcomes in product and labour markets. Focusing on subsets of OECD countries, we look at the implications of product market competition for industry wages and overall employment, and the implications of labour market arrangements for industrial structure and innovation potential. We also look at the potential implications of regulatory reform for employment security and income inequality. We provide empirical evidence on long-run policy interactions by exploiting the cross-country and intersectoral dimensions of the data, though the analysis of employment uses also the time-series dimension.To this end, we relie on a large set of indicators of (economy-wide) labour market policies and institutions and (economy-wide, industry-specific and time-varying) product market regulations. We find that: (a) anticompetitive product market regulations have significant negative effects on non-agricultural employment rates; (b) wage premia generally increase with product market regulations that curb competition, although premia tend to revert to lower levels as market mechanisms are displaced by regulation (e.g. public monopolies); (c) the effects of employment protection policies on innovation activity are significant, with their sign and magnitude depending on industrial relations and technological regimes; (d) countries having stricter regulations tend to specialise in industries with relatively lower R&D intensity and wages; (e) labour market policies and institutional arrangements have significant unintended effects on the size distribution of firms; (f) product market liberalisation may lead to less job security in the most regulated industries, but no empirical support was found for concerns that it could result in a permanent increase in earnings inequality.

Abstract:
Problems of unemployment and low pay amongst the low skilled and those with little work experience are severe in many OECD countries. Employment-conditional schemes are policy instruments designed to increase the employment prospects of the low skilled as well as to support their living standard. In this paper a simple CGE model is developed to simulate the impact of the introduction of an employment-conditional scheme in four OECD countries. The simulated policy package is graduated on gross earnings with both "phase-in" and "phase-out" regions. The advantage of the CGE approach is to allow assessing the direct and indirect effects of the financing of the policy scheme on both labour demand and supply. The simulations suggest that employment effects on targeted households are significant while the impact on aggregate employment is modest. Furthermore, the cost-effectiveness of the policy package is found to depend crucially on the earnings distribution, the levels of taxes on labour and the existence of a severe unemployment trap.

Abstract:
In this paper, we test whether the growth experience of a sample of OECD countries over the past three decades is more consistent with the human-capital augmented Solow model of exogenous growth, or with an endogenous growth model à la Uzawa-Lucas with constant returns to scale to broad (human and physical) capital. We exploit the different non-linear restrictions implied by these two models to discriminate between them. Using pooled crosscountry time-series data, we specify our growth regression by imposing cross-country homogeneity restrictions only on long-run coefficients, while letting the speed of convergence and short term dynamics to vary across countries. While there are indeed good reasons to believe in common long-run coefficients, given that OECD countries have access to common technologies and have intensive intra-industry trade and foreign direct investment, the theoretical models imply that the speed of convergence to the steady state differs across countries because of cross-country heterogeneity in population growth, technical change and progressiveness of the income tax. Therefore, standard dynamic fixed effect specifications, by imposing cross-country homogeneity restrictions on speed of convergence and short-run parameters, suffer from a heterogeneity bias and are not suited to implement our tests. The results suggest a strong effect of human capital accumulation: the estimated long-run effect on output of one additional year of education (about 6-9%) is also within the range of the estimates obtained in microeconomic analyses of the private returns to schooling. Our estimated speed of convergence is too fast to be compatible with the augmented Solow model, while is consistent with the Uzawa-Lucas model with constant returns to scale. This main finding is robust to several robustness tests.

Abstract:
When labor markets are imperfectly competitive, firms may be willing to finance general training if the wage structure is compressed, that is, if the increase of productivity after training is greater than the increase in pay. We propose a novel way of testing this proposition, which exploits the variation in training incidence and in the training wage premium within the European Union. Our results unambiguously show that (general) training incidence is higher in clusters - defined by country, sector, occupation and educational attainment - with a lower training wage premium, measured as the differential between the median wage growth of trained and untrained employees.

Abstract:
We use data from the European Community Household Panel (ECHP) to assess the effects of employee training on the average wage and employment security of different labour market groups in EU countries. We find significant training wage premia only in the case of young or highly educated employees. By contrast training appears to have a strong impact on employment security, measured through subjective measures, in the case of both older and low-educated workers. To reconcile this apparent contradiction, we need to take into account that, as standard in the literature, wage premia are estimated on a truncated sample including only employed workers. Due to downward wage rigidity, those workers who are unable to maintain their productivity are more frequently laid-off - rather than experiencing a wage fall and be retained in employment - and thereby excluded from our sample.

Abstract:
According to Becker [1964], when labour markets are perfectly competitive, general training is paid by the worker, who reaps all the benefits from the investment. Therefore, ceteris paribus, the greater the training wage premium, the greater the investment in general training. Using data from the European Community Household Panel, we compute a proxy of the training wage premium in clusters of homogeneous workers and find that smaller premia induce greater incidence of off-site training, which is likely to impart general skills. Our findings suggest that the Becker model provides insufficient guidance to understand empirical training patterns. Conversely, they are not inconsistent with theories of training in imperfectly competitive labour markets, in which firms may be willing to finance general training if the wage structure is compressed, that is, if the increase in productivity after training is greater than the increase in pay.

Abstract:
We develop a theoretical and empirical analysis of the impact of barriers to entry on workplace training. Our theoretical model yields ambiguous predictions on the sign of this relationship. On the one hand, given the number of firms, a deregulation reduces profits per unit of output, and thereby reduces training. On the other hand, the number of firms increases, and so does the output gain from training, which facilitates the investment in training. Our numerical simulation shows that for reasonable values of the parameters a negative relationship prevails. We use repeated cross section data from the European Labour Force Survey to investigate empirically the relationship between product market regulation and training incidence in a sample of 15 European countries and 13 industrial sectors, which we follow for about 7 years. Our empirical results are unambiguous and show that an increase in product market deregulation generates a sizeable increase in training incidence.

Abstract:
We examine the effect of dismissal regulation on productivity in the OECD, using annual cross-country aggregate data on the stringency of employment protection legislation and industry-level data on productivity from 1982 to 2003. Our empirical results suggest that mandatory dismissal regulations have a depressing impact on productivity growth in industries where layoff restrictions are more likely to be binding. By contrast, we find no evidence of a productivity effect of regulations concerning temporary contracts, which suggests that partial reforms, facilitating the use of fixed-term and atypical contracts, are unlikely to have an important impact on efficiency and technological change and cannot therefore be a substitute for comprehensive reforms whereby dismissal restrictions for open-ended contracts are also weakened.

Abstract:
This paper examines the impact of employment protection legislation on productivity in the OECD, using annual cross-country aggregate data on the degree of regulations and industry-level data on productivity from 1982 to 2003. We adopt a "difference-in-differences" framework, which exploits likely differences in the productivity effect of dismissal regulations in different industries. Our identifying assumption is that stricter employment protection influences worker or firm behaviour, and thereby productivity, more in industries where the policy is likely to be binding than in other industries. The advantage of this approach is that, in contrast with standard cross-country analysis, we can control for unobserved factors that, on average, are likely to have the same effect on productivity in all industries. Our empirical results suggest that mandatory dismissal regulations have a depressing impact on productivity growth in industries where layoff restrictions are more likely to be binding. We present a large battery of robustness checks, including dealing with endogeneity issues, that suggest that our finding is robust.

Abstract:
There is an increasing interest in the process of job creation and destruction as well of hirings and separations. Many studies suggest that idiosyncratic firm-level characteristics shape both job and worker flows in a similar way in all countries. Others argue that cross-country differences in terms of gross job flows are minor. However, these statements are usually based on the comparison of national estimates, typically collected on the basis of different definitions and collection protocols. By contrast, in this paper, we use cross-country comparable data on both job and worker flows to examine key determinants of these flows and of their cross-country differences. We find that idiosyncratic firm (industry, firm age and size) and worker (age, gender, education) characteristics play an important role for both gross job and worker flows in all countries. Nevertheless, in contrast with part of the literature, we find that, even controlling for these factors, cross-country differences concerning both gross job and worker flows appear large and of a similar magnitude. Both job and worker flows in countries such as the United States and the United Kingdom exceed those in certain continental European countries by a factor of two. Moreover, the variation of worker flows across different dimensions is well explained by the variation of job flows, suggesting that, to a certain extent, the two flows can be used as substitutes in cross-country analysis. Consistently, churning flows, that is flows originating by firms churning workers and employees quitting and being replaced, display much less cross-country variation.

Abstract:
Empirical evidence of the impact of policy uncertainty on aggregate investment is mixed. However, if the relationship between policy uncertainty and investment performance is nonlinear, linear regression exercises might not capture the effect of policy uncertainty. In this paper, I present a simple model with investment irreversibility which shows that, in the presence of legal constraints on investment in foreign assets, domestic real investment performance is poorer when liberalization reforms are only partially incredible.

Abstract:
There is no or limited consensus on the quantitative impact of institutions on unemployment, which has led some to question the case for structural reforms. Recent studies suggest also that institutions interact with each other and cannot be analysed in isolation. In this paper, we estimate a standard reduced-form model to explore the institutional determinants of unemployment and assess its robustness using a large battery of robustness checks. We show that, although the impact of each individual policy varies across countries owing to policy interactions, the simple linear model can be used to draw inferences for countries with an average mix of institutions. The model is then extended to encompass systemic interactions, in which individual policies interact with the overall institutional framework. We find relatively robust evidence of broad reform complementarities.

Abstract:
Different training policies can serve different objectives. Institutional arrangements to foster cost-sharing can efficiently increase access to formal, accredited and well-recognized training with little burden for the public budget. Co-financing policies that increase the incentive for firms might reduce the possible impact of market failures on aggregate training provisions and can be easily financed through specific corporate levies. However, these policies cannot reach those groups that are less likely to receive employer-sponsored training. In this case, co-financing policies targeted to individual demand might become necessary. However, these policies are expensive and might result in a substantial waste of public resources if they are not accompanied by interventions to reduce imperfections in the training market. Design is, however, crucial, and it is possible to identify some general principles concerning the desirable characteristics of training policies. Yet, too little is known on their relative efficiency with respect to other potential instruments, due to a lack of rigorous evaluation analysis. Hence, taking into account the methodological complexity of ex-post assessment in this area, evaluation mechanisms should be included into policy design to ensure timely corrections of policy mistakes.

Abstract:
Interaction among autonomous decision-makers is usually modelled in economics in game-theoretic terms or within the framework of General Equilibrium. Game-theoretic and General Equilibrium models deal almost exclusively with the existence of equilibria and do not analyse the processes which might lead to them. Even when existence proofs can be given, two questions are still open. The first concerns the possibility of multiple equilibria, which game theory has shown to be the case even in very simple models and which makes the outcome of interaction unpredictable. The second relates to the computability and complexity of the decision procedures which agents should adopt and questions the possibility of reaching an equilibrium by means of an algorithmically implementable strategy. Some theorems have recently proved that in many economically relevant problems equilibria are not computable. A different approach to the problem of strategic interaction is a "constructivist" one. Such a perspective, instead of being based upon an axiomatic view of human behaviour grounded on the principle of optimisation, focuses on algorithmically implementable "satisfycing" decision procedures. Once the axiomatic approach has been abandoned, decision procedures cannot be deduced from rationality assumptions, but must be the evolving outcome of a process of learning and adaptation to the particular environment in which the decision must be made. This paper considers one of the most recently proposed adaptive learning models: Genetic Programming and applies it to one the mostly studied and still controversial economic interaction environment, that of oligopolistic markets. Genetic Programming evolves decision procedures, represented by elements in the space of functions, balancing the exploitation of knowledge previously obtained with the search of more productive procedures. The results obtained are consistent with the evidence from the observation of the behaviour of real economic agents.
