Standard economic analysis holds that labor market rigidities are harmful for job creation and typically increase unemployment. But many orthodox reforms of the labor market have proved difficult to implement because of political opposition. For these reasons it is important to explain why we...

Returns to scale to capital and the strength of capital externalities play a key role for the empirical predictions and policy implications of different growth theories. We show that both can be identified with individual wage data and implement our approach at the city-level using US Census...

We analyze the channels by which an ill-functioning labor market changes the preferences of the people for public policy and therefore the decisions that are made. We not only discuss labour market reform but other important aspects of policy making such as the size and structure of government...

We estimate the aggregate long-run elasticity of substitution between more and less educated workers (the slope of the demand curve for more relative to less educated workers) at the US state level. Our data come from the (five)1950-1990 decennial censuses. Our empirical approach allows for...

This essay deals with the reasons explaining children’s work in 19th century textile factories and their removal during the first part of the 20th century. The inadequacy of the structure of incomes and expenditures of the household and the very low economic incentives to educate children can...

The identification of aggregate human capital externalities is still not fully understood. The existing (Mincerian) approach confounds positive externalities with wage changes due to a downward sloping demand curve for human capital. As a result, it yields positive externalities even when wages...

This paper examines the associations between obesity, employment status and wages for several European countries. Our results provide weak evidence that obese workers are more likely to be unemployed or tend to be more segregated in self-employment jobs than their non-obese counterparts. We also...

We study the earnings structure and the equilibrium assignment of workers when workers exert intra-firm spillovers on each other. We allow for arbitrary spillovers provided output depends on some aggregate index of workers' skill. Despite the possibility of increasing returns to skills,...

In this paper I construct a search model of a large labor market in which workers are heterogeneous in productivity and (homogeneous) firms post wages and a ranking of workers to direct workers' search. I establish the following results. First, the wage differential is negatively related to...

In a path-breaking but largely overlooked study, published in a festchrift thirty years ago (1975), Herman Van der Wee provided a comparison of prices and real wages of building craftsmen in the regions of Antwerp and south-eastern England, from 1400 to 1700. To do so, he constructed a composite...
