Mobility of workers involves flows of labour, human capital and other production factors and thus contributes to a more efficient allocation of resources. Besides these effects on allocative efficiency, migrant flows affect relative wages and also change the international and national...

In a framework with an upstream monopoly and a downstream duopoly, we analyze the impact of convex costs on the downstream level. In constrast to the case of constant marginal costs, vertical integration does not imply complete market foreclosure. While the nonintegrated downstream ¯rm receives...

The Kyrgyz Republic is one of the largest recipients of international remittances in the world; from a Balance of Payments measure of remittances, it ranked tenth in the world in 2008 in the ratio of remittances to GDP, a rapid increase from 30th place in 2004. Remittances can be used to maintain...

Several German states recently introduced tuition fees for university education. We investigate whether these tuition fees influence the mobility of university applicants. Based on administrative data of applicants for medical schools in Germany, we estimate the effect of tuition fees on the...

The efficiency of the labour market critically depends on the design of its institutions with employment protection legislation (EPL) playing a special role here. However, since formal laws can be observed or ignored to varying degrees, the actual enforcement regime shapes incentives and...

Since the inequality of earnings in East Germany has approached West German levels in the late 1990s, the standard Roy model predicts that a positive selection bias of East-West migrants should disappear. Using a switching regression model and data from the IAB-employment sample, we find however...

This paper investigates the causal effect of geographic labour mobility on income. The returns to German East-West migration and commuting are estimated exploiting the structure of centrally planned economies and a "natural experiment" of German reunification for identification. I find that...

The Chinese growth miracle was based on exports and investment in recent years. While strong output growth has been maintained even during the financial crisis, the imbalances within the country increased. To return to a more sustainable path of development, policies are directed to improve the...

We analyze in this paper the impact of male-dominated migration and remittance income on the participation and hours worked decisions of adults left behind, including the hours spent by women in subsistence and domestic work. We differentiate between a 'pure' migration ("M") effect and the joint...
