In European Welfare States, unskilled workers are typically unionized, while the wage formation of skilled workers is more competitive. To focus on this aspect, we analyze how flexible international outsourcing and labour taxation affect wage formation, employment and welfare in dual domestic...

Mircrosimulation models (MSM) and Computable General Equilibrium models (CGE) have both been widely used in policy analysis. The combination of these two model types allows the utilisation of the advantages of both types. The aim of this paper is to describe the state-of-the-art in simulation...

In 2007 and 2008 Polish governments introduced a series of reforms which led to a substantial reduction in the tax "wedge" (in Polish: "klin") on labour. We show that when considered together the package of introduced reforms brought much greater reductions in the tax burden compared to a widely...

In this paper we develop a discrete model of optimal taxation of married couples and empirically discuss the optimality of income taxation for this group. To this end, we derive the social welfare function which guarantees that joint taxation of married couples is optimal. We will contrast this...

Europeans have worked less than Americans since the 1970s. In this paper, we quantify the relative importance of the extensive and intensive margins of aggregate hours of market work on the observed differences. Our counterfactual exercises show that the two dimensions of the extensive margin,...

This paper characterizes the optimal redistributive taxation when individuals are heterogeneous in two exogenous dimensions: their skills and their values of non-market activities. Search-matching frictions on the labor markets create unemployment. Wages, labor demand and participation are...

Government-run entities are often more labor-intensive than private companies, even with identical production technologies. This need not imply slack in the public sector, but may be a rational response to its wage tax advantage over private firms. A tax-favored treatment of public production...

Decisions by firms and individuals on the extent of their tax payments have generally been treated as separate choices. Empirically, a positive relationship between corporate and personal income tax evasion can be observed. The theoretical analysis in this paper shows that a manager's decision...

A Beveridgean pension scheme invariably introduces a wedge between the wage rate and the marginal take-home pay. A Bismarckian one can do so only if it is not actuarially fair, or in the presence of credit rationing. Interestingly, if the two possible sources of distortion are present at the...

According to the standard principal-agent model, the optimal composition of pay should balance the provision of incentives with the individual demand for insurance. Do income taxes alter this balance? We show that the relative share of PRP on total pay is reduced by higher average taxes, and is...
