This paper surveys major empirical regularities concerning changes in earnings inequality in Europe and the US over the past 25 years. Next, it indicates which of these regularities can be explained within the competitive demand-supply framework of analysis and what is left unexplained. Finally,...

This paper examines the welfare effects of partial trade liberalization when trade is restricted by tariffs, quotas or some combination of both instruments. Rules for optimal first- and second-best intervention are derived and illustrated (using a new geometric technique) in both small and large...

This paper develops a unified model of growth, population, and technological progress that is consistent with long-term historical evidence. The economy endogenously evolves through three phases. In the Malthusian regime, population growth is positively related to the level of income per capita....

This paper develops a growth model in which the endogenous evolution of technological progress and wage inequality is consistent with the observed pattern in the United States and several European economies in the last two centuries. The model accounts for: a) the rise in wage inequality between...

The paper examines the implications of an important aspect of the ongoing reorganization of work – the move from occupational specialization towards multi-tasking – for centralized wage bargaining. The analysis shows how, on account of this reorganization, centralized bargaining becomes...

We estimate scale elasticities in firms' money demand using panel data. Our main data set is a sample of Spanish companies observed over 1983-96. We also analyse comparable UK and US data sets. We find that the errors in money demand equations contain two terms correlated with sales: first, a...

Professional standards vary across professions and also change over time. One profession which has remained perfectionist is classical music, where the amount of practising is striking compared with other professions. Practising is a matter of increasing the reliability of ones skills rather...

This Paper presents new estimates of the impact of job tenure on wages using a new French matched worker-firm dataset. We develop an identification strategy that relies on one specific feature of the French labour laws. They stipulate that firms, when firing workers, must include as one of their...

The paper examines the determinants of the division of labour within firms. It provides an explanation of the pervasive change in work organization away from the traditional functional departments and towards multi-tasking and job rotation. Whereas the existing literature on the division of...

In this paper we argue that an important source of the recent increase in outsourcing is the computer and information technology revolution, characterized by increased rates of technological change. Our model shows that an increase in the pace of technological change increases outsourcing...
