This research shows that moral hazard associated with extant social insurance arrangements causes underinvestment in human capital, because of government’s inability to commit to welfare policies. It then argues that education policies, such as education subsidies or direct public investment...

This paper computes the optimal progressivity of the income tax code in a dynamic general equilibrium model with household heterogeneity in which uninsurable labour productivity risk gives rise to a nontrivial income and wealth distribution. A progressive tax system serves as a partial...

We study the political determination of the level of social long-term care insurance when voters also choose private insurance and saving amounts. Agents differ in income, probability of becoming dependent and of receiving family help. Social insurance redistributes across income and risk...

Across countries, generous social insurance comes along with weak work norms. This finding is often taken to mean that in the long run social insurance generates large output losses. But neither individual nor country data corroborates the view that weak work norms worsen economic performance....

In this paper we argue that very high marginal labor income tax rates are an effective tool for social insurance even when households have preferences with high labor supply elasticity, make dynamic savings decisions, and policies have general equilibrium effects. To make this point we construct...

Outsourcing of labour intensive activities challenges the welfare state and undermines the protection of low-skilled workers. The stylized facts are that profits are concentrated among the high-skilled, involuntary unemployment is mostly among the low-skilled, and private unemployment insurance...

Legislation affects corporate governance and the return to human and financial capital. We allow the preference of a political majority to determine both the governance structure and the extent of labour rents. In a society where median voters have relatively more at stake in the form of human...

Empirical testing of asymmetric information in the insurance market has uncovered a negative correlation between risk levels and insurance purchases, rather than the positive correlation predicted by the standard insurance theory. Hemenway (1990) proposes an explanation for this negative...

This Paper starts from the result of Rochet (1989), that with distortionary income taxes social insurance is a desirable redistributive device when risk and ability are negatively correlated. This finding is re-examined when ex post moral hazard and adverse selection are included, and under...

This proposal involves the establishment of ‘welfare accounts’ for every person in a country. There are four accounts: a retirement account (covering pensions), an unemployment account (covering unemployment support), a human capital account (covering education and training), and a health...
