Multinational companies can exploit the tax advantage of debt more aggressively than national companies by shifting debt from affiliates in low tax countries to affiliates in high tax countries. Previous papers have either omitted internal debt or external debt from the analysis. We are the...

This paper shows that outsourcing of parts of the workforce in unionized firms leads to wage moderation and as long as the share of the outsourced workforce is not too large, this wage-moderation effect on domestic employment outweighs the direct substitution effect so that domestic employment...

We study how harmonization of corporate tax systems affects the stability of international cartels. We show that tax base harmonization reinforces collusive agreements, while harmonization of corporate tax rates may destabilize or stabilize cartels. We also find that bilateral and full...

In oligopolistic industries, increased cost saving opportunities via offshoring have a moderating effect on trade unions. In order to discourage mobile firms from leaving the country, unions accept lower sector wages. In effect, the negotiated wage becomes independent of workers’ bargaining...

Do minimum wages reduce in-work-poverty and wage inequality? Or can alternative policies do better? We evaluate theses issues for the exemplary case of Germany that suffers from high unemployment among low-skilled workers and rising wage dispersion at the bottom of the wage distribution. We...

Using data from the 2006 wave of the German Socio-Economic Panel (GSOEP), this paper analyzes how a minimum wage affects employment, wage inequality, public expenditures, and aggregate income in the low-wage sector. It is shown that a statutory minimum wage of EUR 7.50 per hour would cost...

We develop a model of education where individuals face educational risk. Successfully entering the skilled labor sector depends on individual effort in education and public resources, but educational risk still causes (income) inequality. We show that an optimal public policy consists of...

We study a large economy model in which individuals have private information about their productive abilities and their preferences. Moreover, there is aggregate uncertainty so that the social benefits from taxation and public goods provision are a priori unknown. The analysis is based on a...

In a model with ex-ante homogenous households, earnings risk and a general earnings function, we derive the optimal linear labor tax rate and optimal linear education subsidies. The optimal income tax trades off social insurance against incentives to work and to invest in human capital....

We show in a two-period world with endogenous savings and two assets, one of them exhibiting a stochastic return, that an interest-adjusted income tax is optimal. This tax leaves a riskless component of interest income tax free and taxes the excess return with a special tax rate. There is no...
