We analyze the incidence and welfare effects of unit sales taxes in experimental monopoly and Bertrand markets. We find, in line with economic theory, that firms with no market power are able to shift a high share of a tax burden on to consumers, independent of whether buyers are automated or...

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...

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...

A strictly risk-averse manager makes joint decisions on a firm's tax payments and book profit declarations according to accounting standards. It is analysed how the incentives to overpay or evade taxes and to inflate book profits are influenced by (1) the composition of the manager's...

Firms may evade taxes on profits and can also avoid fulfilling legal restrictions on production activities by bribing bureaucrats. It is shown that the existence of tax evasion does not affect corruption activities at the firm level, while the budgetary repercussions of tax evasion induce less...

A strictly risk-averse individual with an exogenous gross income in period one can acquire human capital in the same period and evade taxes. Period-two income rises with educational investments in period one and can also be hidden from tax authorities. It is shown that a greater tax...

This paper studies the role of beliefs about own performance or appearance for compliance at the customs. In an experiment in which underreporting has a higher expected payoff than truthful reporting we find: a large share, about 15-20 percent of the subjects, is more compliant if they have...

This paper develops a competition theory framework that evaluates an important aspect of the OECD’s Harmful Tax Practices Initiative against tax havens. We show that the sequential nature of the process is harmful and more costly than a “big bang” multilateral agreement. The sequentiality...

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...

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....
