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...

This paper summarizes the study design of the Rural–Urban Migration in China and Indonesia (RUMiCI) project. We first discuss the overall distribution of migrants in Indonesia and the selection of survey cities. Next, we describe the process of identifying the migration status of each...

Large cities produce more output per capita than small cities. This may occur because more talented individuals sort into large cities, because large cities select more productive entrepreneurs and firms, or because of agglomeration economies. We develop a model of systems of cities that...

This study explores to what extent migration has contributed to improved living standards of individuals in Tanzania. Using a 13-year panel survey, the authors find that migration between 1991 and 2004 added 36 percentage points to consumption growth. Although moving out of agriculture resulted...

This paper studies the role of internal migration in income convergence across regions in Japan. Neoclassical theory predicts that migration should have been an important source of convergence, but regression results suggest otherwise. The paper investigates the possibility that this discrepancy...

This paper uses two recent UK surveys to investigate labour market performance, the determinants of language proficiency, and the effect of language on earnings and employment probabilities of non-white immigrants. Our results show that language acquisition, employment probabilities, as well as...

Spatial wage disparities can result from spatial differences in the skill composition of the workforce, in non-human endowments, and in local interactions. To distinguish between these explanations, we estimate a model of wage determination across local labour markets using a very large panel of...

In 1997 GDP per capita in East Germany was 57% of that of West Germany, wage rates were 75% of western levels, and the unemployment rate was at least double the western rate of 7.8%. One would expect that if capital flows and trade in goods failed to bring convergence, labour flows would...
