In fiscal interaction, a policy is evolutionarily stable if, once adopted by all governments, jurisdictions that deviate from it fare worse than those that stick to it. Evolutionary stability is the appropriate solution concept for models of imitative learning (policy mimicking). We show that...

One of the main reasons to include pay-as-you-go (PAYG) schemes in multi-pillared pension systems is that they may entail beneficial risk-sharing and diversification features However, depending on the pension formula these features vary significantly for different types of PAYG schemes. We...

Rather than about absolute payoffs, governments in fiscal competition often seem to care about their performance relative to other governments. Moreover, they often appear to mimic policies observed elsewhere. We study such behaviour in a tax competition game with mobile capital à la...

We propose a dynamic general equilibrium model with human capital accumulation to evaluate the economic consequences of compulsory services (such as military draft or social services). Our analysis identifies a so far ignored dynamic cost arising from distortions in time allocation over the...

We analyse tax competition with corporate income taxes in a common market where tax revenues are allocated according to an apportionment formula. Generally, tax competition is sharper (i.e., equilibrium tax rates are lower) the more tax-elastic is the apportionment formula. This depends on the...

According to many observers, the world is currently getting riskier along many of its dimensions. In this paper we analyse how the welfare state, i.e., social insurance that works through redistributive taxation, should deal with this trend. We distinguish between risks that can be insured by...

Religious participation is much more widespread in the United States than in Europe, while Europeans tend to view sects more suspiciously than Americans. We propose an explanation for these patterns without assuming differences in preferences or market fundamentals. Religious markets may have...

A relatively high labor-intensity in government-run entities need not imply slack in their organization. Rather, it is a rational reaction to various forms of wage tax advantage that the public sector has over private firms. Even though an unequal tax treatment of public and private sectors...

We study the optimal duration of contracts in a principal-agent framework with both moral hazard and adverse selection. Agents decide on a contract-specific and non-verifiable investment. Incentive compatibility requires that initial contracts, which serve to screen the ability of newly hired...

We study the efficiency and distributional consequences of establishing and abolishing the draft in a dynamic model with overlapping generations, taking into account endogenous human capital formation as well as government budget constraints. The introduction of the draft initially benefits the...
