We analyze optimal taxation of labor and capital income in a life-cycle framework with idiosyncratic income risk. We provide a novel decomposition of labor income tax formulas into a redistribution and an insurance component. The latter is independent of the social welfare function and...

In this paper we allude to a novel role played by the non-linear income tax system in the presence of adverse selection in the labor market due to asymmetric information between workers and firms. We show that an appropriate choice of the tax schedule enables the government to affect the wage...

This paper studies the determination of informal long-term care (family aid) to dependent elderly in a worst case scenario concerning the "harmony" of family relations. Children are purely selfish, and neither side can make credible commitments (which rules out efficient bargaining). The model...

This paper studies optimal taxation schemes for education in a search-matching model where the labor market is divided between a high-skill and a low-skill sector. Two public policy targets - maximizing the global employment level and optimizing the social surplus - are studied according to...

This paper considers an economy where individuals differ in productivity and in risk. Rochet (1991) has shown that when private insurance markets offer full coverage at fair rates, social insurance is desirable if and only if risk and productivity are negatively correlated. This condition is...

Economists traditionally tackle normative problems by computing optimal policy, i.e. the one that maximizes a social welfare function. In practice, however, a succession of marginal changes to a limited number of policy instruments are implemented, until no further improvement is feasible. I...

We analyse the deadweight losses of tax-induced labor misallocation in an equilibrium model of the labour market where workers search to climb a job ladder and firms post vacancies. Workers differ in abilities. Jobs differ in productivities and amenities. A planner uses affine tax functions to...

We study optimal income taxation in a framework where one's willingness to report his income truthfully is positively correlated with his type. We show that allowing low-productivity types to cheat leads to Pareto-superior outcomes as compared to deterring them, even if audits can be performed...

This paper presents a comprehensive analysis of the role of capital taxation in advanced economies with a focus on the Swedish experience. We synthesize the existing theoretical literature, present facts about the capital stock and its distribution, review current capital tax practices and...

We analyze the relationship between cognitive ability and bunching in the context of a large and salient kink point of the Swedish income tax schedule. Using population-wide register data from the Swedish military enlistment and administrative tax records, we find that high-ability individuals...
