We show that the standard concertina result for tariff reforms -- i.e. lowering the highest tariff increases welfare -- no longer holds in general if we allow for international capital mobility. The result can break down if the good whose tariff is lowered is not capital intensive. If the...

We analyse the economic impact of a simultaneous aging shock in two countries. The countries are identical in all respects except the financing scheme of their public pension system. While one relies on capitalization, the other one relies on a pay-as-you-go scheme. We show that the two...

We study how inefficiencies of market failure may be further amplified by political choices made by interest groups created in the inefficient market. We take an occupational choice framework, where agents are endowed heterogeneously with wealth and talent. In our model, market failure due to...

We model educational investment, wages and employment status (full-time, part-time or non-participation) in a frictional world in which heterogeneous workers have different productivities, both at home and in the workplace. We investigate the degree to which there might be under-employment and...

Before the early 1970s generous welfare states seemed to be consistent with high employment. Since then, there has been growing concern over disincentive effects of social insurance. This paper suggests that the problem may have arisen in part because European nations were in effect trying to...

This paper argues that increased factor mobility incurs the risk of dismantling the welfare state, even though this state may have useful allocative functions. It will be difficult to finance the welfare state with taxes on capital and it may be necessary to subsidize this factor in the sense...

The paper examines the appropriate domain of the Welfare State by exploring the areas in which free enterprise fails to provide adequate welfare state services. The paper outlines a simple coherent strategy for formulating government welfare state policy by identifying the relevant market...

This paper analyzes welfare-state determinants of individual attitudes towards immigrants - within and across countries - and their interaction with labor-market drivers of preferences. We consider two different mechanisms through which a redistributive welfare system might adjust as a result of...

The paper studies the role of international implications after EU enlargement. Based on a formal model with migration costs for both capital and labor, it predicts a two-sided migration from the new to the old EU countries which is later reversed. As the migration pattern chosen by market forces...

Recent research in the United States and New Zealand has suggested that over the last two decades the age profile of well-being has shifted against children and in favor of the elderly population. This shift has occurred because welfare systems have become increasingly generous towards older...
