Since World War II, direct stock ownership by households has largely been replaced by indirect stock ownership by financial institutions. We argue that tax policy is the driving force. Using long time-series from eight countries, we show that the fraction of household ownership decreases with...

The paper presents a stochastic insider-outsider model that accounts for the following stylized facts: (1) unemployment rates display a high degree of serial correlation, or `persistence'; (2) the average rate of unemployment has been higher in the United States than in Europe over the 1950s and...

The paper analyses complementarities among a variety of labour market policies. It shows: (a) that a wide range of labour market institutions (e.g. unemployment benefits, job security legislation and payroll taxes) have complementary effects on unemployment; and thus (b) that policies aimed at...

We explore the far-reaching implications of replacing current unemployment benefit (UB) systems by an unemployment accounts (UA) system. Under the UA system, employed people are required to make ongoing contributions to their UAs and the balances in these accounts are available to them during...

Unemployment insurance and employment protection are typically discussed and studied in isolation. ln this paper, we argue that they are tightly linked, and we focus on their joint optimal design in a simple model, with risk averse workers, risk neutral firms, and random shocks to productivity....

Temporary employment contracts allowing unrestricted dismissals were introduced in Spain in 1984 and quickly came to account for most new jobs. In 1997, however, the Spanish government attempted to reduce the incidence of temporary employment by reducing payroll taxes and dismissal costs for...

This paper analyzes the effects of income taxation on the international migration and earnings of top earners using a Danish preferential foreigner tax scheme and population-wide Danish administrative data. This scheme, introduced in 1991, allows new immigrants with high earnings to be taxed at...

We study the impact of local taxation on the location and growth of firms. Our empirical methodology pairs establishments across jurisdictional boundaries to estimate the impact of taxation. Our approach improves on existing work as it corrects for unobserved establishment heterogeneity, for...

Economists traditionally tackle normative problems by computing optimal policy, ie 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 call...

This Paper explores the optimal role of the tax system in alleviating labour-market imperfections and raising revenue. For this purpose, the standard search model of the labour market is extended by introducing scarce entrepreneurial talent and arbitrage between the supply and demand. We study...
