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...

In order to credibly "sell" legitimate children to their spouse, women must forego more attractive mating opportunities. This paper derives the implications of this observation for the pattern of matching in marriage markets, the dynamics of human capital accumulation, and the evolution of the...

This Paper analyses the economic issues associated with human cloning and new reproductive technologies. We analyse the incentives for human cloning and its implications for the long run distribution of skills and income. We analyse models of human cloning for different motives, focusing on...

This Paper studies a model where Information Technology, while typically increasing overall inequality, is likely to harm some people at intermediate and high levels of the distribution of income but to benefit people at the bottom; where within a given occupation it may harm some workers while...

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 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...

This paper develops a matching model of the labour market under wage rigidity when hiring decisions are irreversible. There are two types of workers, the skilled and the unskilled. The model is used to analyse whether technological advances may have increased unemployment, and shows that this is...

This paper develops a model to analyse the implications of firing costs on incentives for R&D and international specialization. The key idea is that, to avoid paying firing costs, the country with a rigid labour market will tend to produce relatively secure goods, at late stages in their product...

A model of the labour market under firing restrictions and endogenous quits is constructed. It is shown that in the spirit of Blanchard and Summers (1988), the model can generate multiple equilibria, with a low-quits/high-unemployment equilibrium coexisting with a high-quits/low-unemployment...

Economists traditionally tackle normative problems by computing optimal policy, ie the one that maximizes a social welfare function. In practice, however, a succession of marginal changes to a limited number of policy instruments are implemented, until no further improvement is feasible. I call...
