Feenstra and Ma (2008) develop a monopolistic competition model where firms choose their optimal product scope by balancing the profits from a new variety against the costs of 'cannibalizing' sales of existing varieties. While more productive firms always have a higher market share, there is no...

Losing a parent is a trauma that has consequences for human capital formation. Does it matter at what age this trauma occurs? Using longitudinal data from the Kagera region in Tanzania that span thirteen years from 1991-2004, we find considerable impact heterogeneity across age at bereavement,...

This paper examines the long-run effect of FDI on health in developed countries. Using panel cointegration techniques, we find a significant and negative long-run effect. -- FDI ; health ; panel cointegration

This paper examines the long-run effect of foreign aid on income inequality for 21 recipient countries using panel cointegration techniques to control for omitted variable and endogeneity bias. We find that aid exerts an inequality increasing effect on income distribution. -- Inequality ;...

This paper argues that previous cross-country (panel) studies on the relationship between income inequality and health suffer from significant biases due to (i) omitted country-specific factors, (ii) endogeneity, and (iii) cross-country heterogeneity in the impact of inequality on health. Using...

Whole-household migration potentially can alter the results of studies on income inequality based on panel data if it selects on household income. We model whole-household migration and its impacts on income inequality and poverty using a unique, nationally representative household panel data...

This paper investigates the reservation wages of unemployed persons on the basis of a job-search model with non-static reservation wages using panel data from Germany from 1987 to 1998. The results suggest that reservation wages are relatively high in Germany compared to other countries....

This paper studies the reservation wages of unemployed persons and the wages offered them in Germany from 1987 to 1998, whereby special focus is placed on unemployment duration. The results of the study indicate that in contrast to reservation wages, offered wages decline considerably with...

We develop a general-equilibrium model to capture key features of the retailing and of the manufacturing industry in order to understand how these two industries interact and how labor is allocated between them. We show that the observed shift in employment from manufacturing to retailing, the...
