Impact evaluations of development programmes usually focus on a comparison of participants with a control group. However, if the programme generates externalities for non-participants such an approach will capture only part of the programme’s impact. Based on a unique large-scale quantitative...

Empirical work in labour economics has focused on rent sharing as an explanation for the observed correlation in cross-sections between wages and profitability. The alternative explanation of risk sharing between workers and employers has not been tested. Using a unique panel data set for four...

We analyze the impact of adolescents' friendship relations in their final-year class of high school on subsequent labor market success. Based on a typology of network positions we locate each student within the social system of the school class as either: an <I>isolate</I>, a <I>sycophant</I>, a <I>broker</I> or a...</i></i></i></i>

Based on micro-data on individual workers for the period 2000-2005, we show that wage differentials in the Netherlands are small but present. A large part of these differentials can be attributed to individual characteristics of workers. Remaining effects are partially explained by variations in...

Most measures of vulnerability are a-theoretic and essentially static. In this paper we use a stochastic Ramsey model to find a household's optimal welfare and we measure vulnerability as the shortfall from the welfare attained if the household consumed permanently at the poverty line. The...

Division of labor models have become a standard analytical tool, along with competitive general equilibrium models (Ricardian, HOS, Ricardo-Viner), in public finance, trade, growth, development, and macroeconomics. Yet unlike the earlier models, specialization models lack a canonical...

There has been a revival of interest in the effect of risk on economic growth. We quantify both ex ante and ex post effects of risk using a stochastic version of the Ramsey model. We develop a simulation-based econometric methodology which allows us to estimate the model in the structural form...

To achieve sustainable economic growth in transition countries, it is crucial that enterprise performance is improved. However, it is not a priori clear which factors are essential for this. For Russia, data to investigate the potential determinants of enterprise performance is scarce....

Xiaokai Yang's theory of economic specialization under increasing returns to scale is a formal development of the fundamental Smith-Young theorem on the extent of the market and the social division of labor. In this theory specialization and, thus, the social division of labor is firmly embedded...

Using a unique panel data set for rural households in Zimbabwe we estimate a
