The famous events of May 1968, starting with student riots, threw France into a state of turmoil. The period of ?revolution? coincided with the time in which important examinations are undertaken. Normal procedures were abandoned and the pass-rate for various qualifications increased enormously....

This article is an idiosyncratic survey of the insider-outsider theory, describing the vision underlying the theory, and evaluating salient contributions to the literature in the light of this vision. We also indicate what appear to have been dead-ends and red herrings in past research. The...

Most countries exhibit large and persistent geographical differences in wages, income and unemployment rates. A growing class of place based policies attempt to address these differences through public investments and subsidies that target disadvantaged neighborhoods, cities or regions. Place...

Haavelmo's seminal 1943 paper is the first rigorous treatment of causality. In it, he distinguished the definition of causal parameters from their identification. He showed that causal parameters are de fined using hypothetical models that assign variation to some of the inputs determining...

We present identification and estimation results for the collective model of labour supply in which there are discrete choices, censoring of hours and nonparticipation in employment. We derive the collective restrictions on labour supply functions and contrast them with restrictions implied by...

The apparently unrelenting growth in the GDP-share of health spending (SHS) has been a perennial issue of policy concern. Does an equilibrium limit exist? The issue has been left open in recent dynamic models which take income growth and population aging as given. We view these variables as...

The UK and the US have experienced both rising skill premia and rising employment of skilled workers since the 1980s. These trends are typically interpreted as concurrent shifts of relative skill supplies and demands, and the demand shifts are attributed to skill-biased technological change or...

This paper provides some empirical evidence and a theory of the relationship between residual wage inequality and the increasing dispersion of capital/labor ratios across firms. I document the increasing variance of capital/labor ratios across firms in the US labor market. I also show that the...

The ?prospect of upward mobility? (POUM) hypothesis formalised by Benabou and Ok (2001a) finds explicit assumptions under which some individuals that are poorer than the average optimally choose to oppose redistribution policies. The underlying intuition is that these individuals rationally...

In this paper, we study gains and losses that accrue to natives because of immigration. The gain on the aggregated level is called the ?immigration surplus?, which can be seen as analogous to a consumer surplus. We derive changes in the earnings of native owners of production factors by...
