Economists have long viewed recessions as contributing to increasing inequality. This conclusion is largely based on data from a period in which inequality was increasing over time, however. This Paper examines the connection between long-run trends and cyclical variation in earnings inequality....

This paper considers an economy where skilled and unskilled workers use different technologies. The rate of improvement of each technology is determined by a profit-maximizing R&D sector. When there is a high proportion of skilled workers in the labour-force, the market for skill-complementary...

This Paper claims that technical progress induces early retirement of older workers. It supports this claim both theoretically and empirically. We present a model where part of human capital is technology-specific, so that technical progress erodes some existing human capital. This affects...

We use two UK panel data sets to investigate skill-upgrading in the United Kingdom and how it has been affected by computerization. Census data reveals that most aggregate skill-upgrading is explained by within-firm rises in skill composition. Such upgrading is significantly related to...

How does the relationship between earnings and schooling change with the introduction of comprehensive economic reform? This Paper uses a unique dataset (covering about 3 million Hungarian wage earners, from 1986 to 1998) and a novel procedure to correct sample selection bias (based on DiNardo,...

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...

How valuable are the skills acquired under socialism in a market economy? This Paper throws light on this question using unique data covering the years before and during transition (1986-98) for about 3 million Hungarian wage earners. We find that returns to a year of schooling increased by 75%...

In this Paper, we analyse the extent to which market forces create an incentive for cloning human beings. We show that a market for cloning arises if a large enough fraction of the clone's income can be appropriated by its model. Only people with the highest ability are cloned, while people at...

We consider a labor market search model where, by working longer hours, individuals acquire greater skills and thereby obtain better jobs. We show that job inequality, which leads to within-skill wage differences, gives incentives to work longer hours. By contrast, a higher probability of losing...

This paper explores the implications of Unified Growth Theory for the origins of existing differences in income per capita across countries. The theory sheds light on three fundamental layers of comparative development. It identifies the factors that have governed the pace of the transition from...
