Age data frequently display excess frequencies at attractive numbers, such as multiples of five. We use this "age heaping" to measure cognitive ability in quantitative reasoning, or "numeracy". We construct a database of age heaping estimates with exceptional geographic and temporal coverage,...

We examine the growth performance of Sweden in the post-World War II period, focusing on explaining the relative decline of economic growth in Sweden since the early 1970's. The hypothesis that the relative decline is a consequence of productivity catch-up is rejected. A number of potential...

Mobility of workers involves flows of labour, human capital and other production factors and thus contributes to a more efficient allocation of resources. Besides these effects on allocative efficiency, migrant flows affect relative wages and also change the international and national...

In an influential paper Mankiw, Romer and Weil (1992) argue that evidence on the international disparity in levels of per-capita income and rates of growth is consistent with a standard Solow model, once it has been augmented to include human capital as an accumulable factor. In a study on...

If redistribution is distortionary, and if the income of skilled workers is due to knowledge-intensive activities and depends positively on intellectual property, a social planner which cares about income distribution may in principle want to use a reduction in Intellectual Property Rights...

This paper uses a unique database that provides value-added, employment, and population levels for the entire set of French departments for the years 1860, 1930, and 2000. These data cover three sectors: agriculture, manufacturing, and services. This allows us to study the evolution of spatial...

We use data on imports of computer equipment for a large sample of countries between 1970-90 to investigate the determinants of computer-technology adoption. We find strong evidence that computer adoption is associated with higher levels of human capital and with manufacturing trade openness...

It is clear that education has an important effect on wages paid in the labour market. It is not clear, however, whether this is due to the role that education plays in raising the productivity of workers (the human capital explanation) or whether education simply reflects the ability of the...

This paper studies the effects of labour income taxation on growth in an OLG model where both formal schooling and child care enter the human capital production function as complements. We compare them with the effects obtained in a model where only formal schooling matters for skill formation....

This Paper explores the relationship between environmental protection and international capital movements, when tax policy is endogenous (through voting). A two-period general equilibrium model of a small open economy is specified to compare the effects of two different constitutions (commitment...
