We develop a general equilibrium analysis of the impact of active labour market policy on unemployment, wages and the welfare of the employed. This framework is used to assess the political support in favour of such policies and to relate it to the working of such policies and other parameters...

This Paper develops a model for analysing the costs and benefits of intellectual property enforcement in LDCs. The North is more productive than the South and is the only source of innovator. There are two types of goods, and each bloc has a comparative advantage in producing a specific type of...

This Paper analyses the welfare effects of price restrictions on private contracting in a world where agents have a limited cognitive ability. People compute the costs and benefits of entering a transaction with an error. The government knows the distribution of true costs and benefits as well...

The Internet plays a growing role in the economy. This paper extrapolates this trend and analyses a world where most transactions take place in "cyberspace". We ask the following question: how does the design of the search engine affect the incentives to innovate and the economy’s long run...

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...

We develop a two-sector model in which technological progress alternatively raises the productivity of one sector after another. We assume that goods are <MI>complements<D> for the final consumers. The sector which benefits from technical progress will see a resulting <MI>fall in its price<D>. In this model,...</d></mi></d></mi>

During the nineties, unemployment fell in a number of European countries while it remained high in others. This Paper discusses potential causes for that evolution in light of recent economic research, emphasizing obstacles to reform due to political constraints, the prevalence of ideology, and...

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...

I study how savers allocate funds between boundedly rational firms which follow simple pricing rules. Firms need cash to pay their inputs in advance, and savers-shareholders allocate cash between them so as to maximize their rate of return. When the rate of return on each firm is observed, there...

Over recent years `opportunity cost' (OC) models of growth have been constructed which suggest that firms take advantage of the possibility of intertemporal subsitution in order to engage in productivity-improving activities during recessions. This paper tests whether this argument is correct,...
