It is argued that a PAYGO system may have useful allocative functions in that it serves as an insurance against not having children and as an enforcement device for 'rotten kids' who are unwilling to pay their parents a pension. It is true that the system has a moral hazard effect in terms of...

Intergenerational inequality and old-age poverty are salient issues in contemporary China. China's aging population threatens the fiscal sustainability of its pension system, a key vehicle for intergenerational redistribution. We analyze the positive and normative effects of alternative pension...

When credit markets to finance investment in the human capital of young people are missing, the competitive equilibrium allocation is inefficient. When generations overlap, this failure can be mitigated by properly designed social institutions such as public education and public pensions. We...

In this paper we document a strong positive correlation of immigration flows with changes in average wages and average house rents for native residents across U.S. states. Instrumental variables estimates reveal that the correlations are compatible with a causal interpretation from immigration...

Despite convergence pressures, differences in housing and financial market institutions across the 15 member states of the European Union are still enormous. This paper argues that they have profound effects on the responsiveness of output and inflation in the different countries to changes in...

Typically, a small and open economy trades goods at given world prices. Here, we present a model of a very open small economy, where capital and labour are internationally mobile, too. When investing into infrastructure, the economy’s government attracts not only mobile capital but mobile...

The striking geographical concentration of economic activities suggests that there are substantial benefits to agglomeration. The nature of those benefits remains unclear, however. In this Paper we take advantage of a new dataset to quantify the role of one of the main contenders: the matching...

Pre-harvest lean seasons are widespread in the agrarian areas of Asia and Sub-Saharan Africa. Every year, these seasonal famines force millions of people to succumb to poverty and hunger. We randomly assign an $8.50 incentive to households in Bangladesh to out-migrate during the lean season, and...

Crime has been argued to have important externalities. We investigate the relationship between violent crime and an important type of behaviour: individuals’ participation in their local area through walking and physical activity. We use a sample of nearly 1 million people residing in over 320...

We propose an integrated framework to discuss the empirical literature on the local determinants of agglomeration effects. We start by presenting the theoretical mechanisms that ground individual and aggregate empirical specifications. We gradually introduce static effects, dynamic effects, and...
