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...

This paper explores the implications of the ongoing reorganization of firms for inequality in the labour market. We show how recent technological advances in physical and human capital can lead to the breakdown of occupational barriers, creating demands for new combinations of skills, and...

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...

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...

This paper studies the impact of income inequality on fiscal conservatism when an increase in inequality affects the bottom portion of income distribution. It is argued that, contrary to what is generally assumed in the economic literature, inequality will then be associated with less, rather...

In an overlapping generations model, rents to human capital play a key role in increasing savings. In the absence of such rents, the return to human capital is entirely appropriated by the old and accumulation is entirely determined by the income to fixed factors. If rents are introduced by...

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...

Poor families around the world spend a large fraction of their income on consumption of goods that appear to be useless in alleviating poverty, while saving at very low rates and neglecting investment in health and education. Such consumption patterns seem to be related to the persistence of...

This paper presents a unified theory that provides an intertemporal reconciliation between conflicting viewpoints about the effect of inequality on economic growth. It argues that the replacement of physical capital accumulation by human capital accumulation as a prime engine of economic growth...
