How can we explain the success of cooperative networks of firms that share innovations, such as Silicon Valley or the Open Source community? This Paper shows that if innovations are cumulative, making an invention publicly available to a network of firms may be valuable if the firm expects to...

This Paper uses US Census data from 1990 and 2000 to provide evidence on the labour market characteristics of European-born workers living in the US. It is found that there is a positive wage premium associated with these workers, and that the highly skilled are over-represented compared with...

This Paper analyses the evolution of quantitative measures of employee rents in Europe during the nineties, using the European Household Panel Survey. I look at two classes of measures: wage differentials between workers along industry and firm size dimensions; and estimated welfare differences...

The historical record suggests that economic development is associated with the rise of the financial sector. This rise is often triggered by exogenous events such as large budget deficits generated by wars or the availability of large investment projects such as railroads. This paper discusses...

In this paper we argue that employment protection legislation is more likely to arise when the rents earned by the employed over their alternative wage is greater. The model explains why economies with greater real wage rigidity also have greater employment protection. The model also predicts...

This survey discusses the effect of macroeconomic fluctuations on long-run growth from both a theoretical and empirical perspective. It emphasizes the ‘opportunity cost’ approach, which states that firms will intertemporally substitute productivity-enhancing activities for regular production...

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...

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...

The distributional effects of the minimum wage are analysed in a model where skilled and unskilled labour enter the production function. It is argued that distributional goals are best achieved by letting the labour market clear and achieving redistribution through taxes and transfers.

This paper studies the dynamics of fundamental research. We develop a simple model where researchers allocate their effort between improving existing fields and inventing new ones. A key assumption is that scientists derive utility from recognition from other scientists. We show that the economy...
