This paper analyzes a fully funded social security system under the assumption that agents face temptation issues. Agents are required to save through individually managed Personal Security Accounts without, and with mandatory annuitization. When the analysis is restricted to CRRA preferences...

Low international competitiveness of a set of euro area countries, which have become evident by large current account deficits and rising risk premiums on government bonds, is one of the most challenging economic policy issues for Europe. We analyse the role of private restructuring and public...

The current unemployment insurance and employment protection legislation were set up in an environment in which relationships between workers and firms were typically long-lasting and stable. The increasing globalisation of the economy and the rapid technological and organisational changes...

We extend economic equivalence results, like the Ricardian equivalence proposition, to the political sphere where policy is chosen sequentially. We derive conditions under which a policy regime (summarizing admissible policy choices in every period) and a state are politico-economically...

Many countries face the problem of how to reform social security systems to cope with increasing life expectancy. This raises questions concerning both distribution and risk sharing across generations. These issues are addressed within an OLG model with stochastic life expectancy across...

We study the design of parental leave systems through the lens of an estimated model of parents’ joint willingness to pay for parental leave. We estimate the model using Danish register data on almost 200,000 births combined with sharp variation in economic incentives created by the parental...

In this model of education, where individuals are exposed both to educational risk and to wage risk within the skilled sector, successful graduation depends both on individual effort to study and on public resources. We show that insuring the present risks is a dichotomic task: Wage risk is...

This paper analyzes the welfare effects of the Italian social security system in an economy with uncertainty on wages, financial market returns and life expectancy. The introduction of a pension system reproducing the Italian statutory scheme turns out to decrease ex-ante individual welfare,...

This paper analyzes optimal linear taxes on labor income and savings in a standard two-period life-cycle model with endogenous leisure demands in both periods and non-insurable income risks. Households are subject to skill shocks in both periods of the life-cycle. We allow for completely general...

Recent debates have suggested that taxation is very detrimental to labour force participation and employment. However, some countries - notably the Scandinavian - stand out as contradictions to this view since they have managed to sustain high labour force participation rate despite high tax...
