Abstract:
This paper explores the economic consequences of the enlargement of the European Union with countries from Central and Eastern Europe. We focus on integration aspects that go beyond the reduction of formal trade barriers, namely accession to the internal market and free movement of labour. The economic implications for sixteen industries in several European countries are assessed by using WorldScan, a CGE model for the world economy. The results suggest that the candidate member states will gain substantially from accession to the internal market, although some sectors in these countries will shrink. Most EU countries will experience small welfare increases. We also find that the internal market effects are large compared to the economic effects of removing formal trade barriers and migration.

Abstract:
We explore the economic implications of the possible Turkish accession to the European Union. We focus on three main changes associated with Turkish membership: (i) accession to the internal European Market; (ii) institutional reforms in Turkey triggered by EU membership; and (iii) migration in response to the free movement of workers. Overall, the macroeconomic implications for EU countries are small but positive. European exports increase by around 20 percent. Turkey experiences larger economic gains than the EU: consumption per capita is estimated to rise by about 4 percent as a result of accession to the internal market and free movement of labour. If Turkey would succeed in reforming its domestic institutions in response to EU-membership, consumption per capita in Turkey could raise by an additional 9 percent. These benefits would spill over to the EU.

Abstract:
More competition among banks typically enhances the welfare of consumers. However, it may also involve a threat to financial stability, that is of vital importance for the functioning of economies. This study reveals that many forms of competition do not endanger financial stability, however. For instance, intensified competition among incumbant banks usually has little impact on financial stability. Moreover, in cases where competition does affect financial stability, the latter might best be safeguarded by sound prudential regulation or good corporate governance.

Abstract:
This paper reviews the empirical literature on the impact of company taxes on the allocation of foreign direct investment. We make the outcomes of 25 empirical studies comparable by computing the tax rate elasticity under a uniform definition. The mean value of the tax rate elasticity in the literature is around -3.3, i.e. a 1%-point reduction in the host-country tax rate raises foreign direct investment in that country by 3.3%. There exists substantial variation across studies, however. By performing a meta analysis, the paper aims to explain this variation by the differences in characteristics of the underlying studies. Systematic differences between studies are found with respect to the type of foreign capital data used, and the type of tax rates adopted. We find no systematic differences in the responsiveness of investors from tax credit countries and tax exemption countries.

Abstract:
Meta-analysis is a research method to synthesise previously obtained research results. It is best seen as a statistical approach towards reviewing and summarising the literature. This paper aims to introduce and critically review the research method of meta-analysis and to illustrate its potential use in applied economic policy analysis. Special attention will be paid to the possibilities for value transfer and the possibilities to improve the calibration of existing macroeconomic policy models.

Abstract:
A flat tax rate on income has gained popularity in European countries. This paper assesses the attractiveness of such a flat tax in achieving redistributive objectives with the least cost to labour market performance. We do so by using a detailed applied general equilibrium model for the Netherlands. The model is empirically grounded in the data and encompasses decisions on hours worked, labour force participation, skill formation, wage bargaining between unions and firms, matching frictions, and a wide variety of institutional details. The simulations suggest that the replacement of the current tax system in the Netherlands by a flat rate will harm labour market performance if aggregate income inequality is contained. This finding bolsters the notion that a linear tax is less efficient than a non-linear tax to obtain redistributive goals.

Abstract:
This paper performs a meta-analysis of empirical estimates of uncompensated labour supply elasticities. We find that much of the variation in elasticities can be explained by the variation in gender, participation rates, and country fixed effects. Country differences appear to be small though. There is no systematic impact of the model specification or marital status on reported elasticities. The decision to participate is more responsive than is the decision regarding hours worked. Even at the intensive margin, we find that the elasticity for women exceeds that for men. For men and women in the Netherlands, we predict an uncompensated labour supply elasticity of 0.1 and 0.5, respectively. These values are robust for alternative samples and specifications of the meta regression.

Abstract:
This paper estimates Nash-type fiscal reaction functions for European governments competing for revenue from diesel excises. It appears that European governments strategically set their excise levels by responding to their neighbors' tax rates. This provides evidence for the presence of tax competition in diesel excises. In fact, a 10% higher rate in neighboring countries (in terms of the user price) induces a country to raise its own rate by between 2 and 3%. This impact is robust for alternative specifications. By imposing restrictions on excise levels, EU harmonization of excises in 1987 and the introduction of a minimum in 1992 exerted a positive impact on the excise level in a number of EU countries. It has not, however, significantly reduced the intensity of tax competition. Indeed, strategic tax responses have not significantly been reduced by these harmonization policies. We also find that high-tax countries appear to compete more aggressively than low-tax countries in the sense that they feature larger strategic tax responses. There is no significant difference between large and small countries.

Abstract:
This paper analyses the impact of corporate taxes on structural unemployment, using an applied general equilibrium model for the European Union. We find that the unemployment and welfare effects of corporate taxes differ considerably among European countries. The magnitude of these effects rises in particular in the broadness of the corporate tax base of a country, and the strength of international spillover effects through foreign direct investment. The effect on unemployment is smaller if the substitution elasticity between labour and capital is large, if international spillover effects operate primarily via multinational profit shifting, and with small labour market imperfections. Although the effect of corporate taxes on unemployment may be smaller than the effect of labour and value-added taxes (e.g. under relatively strong real wage resistance), the welfare costs of corporate taxation are typically larger for most European countries under plausible parameters, especially under strong international spillovers.

Abstract:
This paper develops a model of search on the labour market with training. The model reveals how the tax system can restore the social optimum if the Hosios condition is not satisfied in the private equilibrium. Furthermore, the effects are explored of a second-best reform from average to marginal taxes when a given amount of public revenue has to be raised. We find that (i) a marginal wage tax is less distortionary to raise revenue than is an average tax per job, provided that training is not distorted initially; (ii) this conclusion may reverse in the presence of training distortions; (iii) marginal wage taxes are less distortionary in economies characterized by commitment in wage bargaining, such as the European labour market. Hence, tax reforms that reduce the average tax per job and raise the marginal wage tax, such as an EITC or a negative income tax, are more attractive in Europe than in the US.

Abstract:
This paper employs MIMIC, an applied general equilibrium model of the Dutch economy, to explore various tax cuts aimed at combating unemployment and raising labor supply. MIMIC combines modern labor-market theories, a firm empirical foundation detailed description of Dutch labor-market institutions. We develop a small aggregate model which contains the core of MIMIC, namely wage setting, job matching, labor supply demand. In addition to illustrating the main economic mechanisms in MIMIC shows the advantages of employing a larger, more disaggregated model that accounts for heterogeneity, institutional details, and more economic mechanisms. Targeting in-work benefits at the low skilled is the most effective way to cut economy-wide unemployment quality and quantity of labor supply. Cuts in social security contributions paid by employers and subsidies for hiring long-term unemployed reduce unskilled unemployment most substantially. Tax cuts in the higher tax brackets boost the quantity and quality of formal labor supply but are less effective in reducing unemployment and in raising unskilled employment and female labor supply.

Abstract:
This paper deals with the so-called "double dividend" of an environmental tax reform. Using a model with only labor and polluting inputs as factors of production, we find that society faces a trade-off between internalizing environmental externalities and raising revenues in the least distortionary way. However, if capital enters the production structure, an ecological tax reform may render the tax structure more efficient from a non-environmental point of view, thereby raising not only environmental quality but also private incomes.
