Contests between groups are plagued by intra-group externalities (freeriding). Yet, costless incentive schemes that entirely avoid free-riding within a group might not be desirable, neither individually nor socially. In contests among two groups, a relatively weak (i.e., small or unproductive)...

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...

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 work). Our analysis identifies a so far ignored dynamic cost arising from distortions in time allocation over the life...

Pay-as-you-go (PAYG) pension schemes can contribute to better intergenerational risk-sharing and diversification. However, different variants of PAYG schemes entail different properties in these respects. In a stochastic 2-OLG model we compare PAYG schemes with fixed contribution rates and such...

Critical-level (CL) utilitarianism with both fixed and variable critical levels is applied to the problem of redistribution in a federation with free mobility. We are interested in intra-regional inequality when redistribution policies are organized decentrally in a federation. Due to free...

In an occupational choice framework individuals can either become entrepreneurs (risky income) or employed workers (safe income). Their choice is affected by the design of the pension system which discriminates between entrepreneurs and workers. We explore the comparative statics of several...
