I argue that distinguishing between life expectancy at birth and life expectancy beyond the crucial early childhood years affects the relationship between life expectancy and schooling in a meaningful way. In particular, I show that while the change in life expectancy at birth between 1960 and...

This paper offers new tests of the `convergence hypothesis'. It first analyses the pattern of growth of measured inputs (human and physical capital conventionally measured by an inventory method) and shows that these tests sustain the hypothesis. On the other hand, when the pattern of growth of...

Using a human-capital-based growth model, we show the essential role of labour mobility and cross-country tax harmonization in equalizing income levels of countries that start off from different initial income positions. Knowledge spillovers cum labour mobility are the driving forces behind the...

The paper develops two models in which parents support their adult child’s human capital investment through financial transfers and/or coresidence. In one, parents are altruistic, and in the other they make loans to children for purely selfish reasons. Econometric estimates using the first...

Under communism, workers had their wages set according to a centrally-determined wage grid. In this paper we use new micro data on men to estimate returns to human capital under the communist wage grid and during the transition to a market economy. We use data from the Czech Republic because it...

We construct a revised version of the Barro and Lee (1996) data set for a sample of OECD countries using previously unexploited sources and following a heuristic approach to obtain plausible time profiles for attainment levels by removing sharp breaks in the data that seem to reflect changes in...

Many writers have claimed that R&D has two 'faces'. In addition to the conventional role of stimulating innovation, R&D enhances technology transfer by improving the ability of firms to learn about advances in the leading edge ('absorptive capacity'). In this paper we document that there has...

This research develops an evolutionary growth theory that captures the interplay between the evolution of mankind and economic growth since the emergence of the human species. This unified theory encompasses the observed evolution of population, technology and income per capita in the long...

This paper analyses the interaction between the distribution of human capital, technological progress, and economic growth. It demonstrates the significant role of the distribution of human capital in the process of economic development. The evolutionary pattern of the human capital...

This paper examines how economic stratification affects inequality and growth over time. It studies economies where heterogenous agents interact through local public goods or externalities (school funding, neighbourhood effects) and economy-wide linkages (complementary skills, knowledge...
