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...

The paper deals with the effects of migration resulting from EU Eastern enlargement on the welfare states of Western Europe. Although migration is good in principle, as it yields gains from trade and specialization for all countries involved, it does so only if it meets with flexible labour...

We report on several experiments on the optimal allocation of ownership rights. The experiments confirm the property rights approach by showing that the ownership structure affects relationship-specific investments and that subjects attain the most efficient ownership allocation despite starting...

We show experimentally that fairness concerns may have a decisive impact on both the actual and the optimal choice of contracts in a moral hazard context. Explicit incentive contracts that are optimal according to self-interest theory become inferior when some agents value fairness. Conversely,...

Civil servants have a bad reputation of being lazy. However, citizens' personal experiences with civil servants appear to be significantly better. We develop a model of an economy in which workers differ in laziness and in public service motivation, and characterise optimal incentive contracts...

The risk of investment in schooling has largely been ignored. We assess the variance in the rate of return by surveying the international empirical literature from this fresh perspective and by simulating risky earnings profiles in alternative options, choosing parameters on basis of the very...

This paper explores the meaning and implications of the desire by workers for impact. We find that this impact motive can make firms in a competitive labor market act as monopsonists, lead workers with the same characteristics but at different firms to earn different wages, may alleviate the...

We characterize the equilibrium of a search model with a continuum of job and worker types, wage bargaining, free entry of vacancies and on-the-job search. The decentralized economy with monopsonistic wage setting yields too many vacancies and hence too low unemployment compared to first best....

This paper explores the existence of downward real wage rigidity (DRWR) in 19 OECD countries, over the period 1973-1999, using data for hourly nominal earnings at industry level. Based on a nonparametric statistical method, which allows for country and year specific variation in both the median...

Recent micro studies have documented extensive downward nominal wage rigidity (DNWR) for job stayers in many OECD countries, but the effect on aggregate variables remains disputed. Using data for hourly nominal wages, we explore the existence of DNWR on wages at the industry level in 19 OECD...
