This study investigates the role of stratification of health and income in the social cost of healthrelated early retirement, as evidenced in the German Socio-economic Panel (GSOEP). We interpret early retirement as a mechanism to limit work-related declines in health that allows poorer and less...

We consider a portfolio optimization problem in a Black-Scholes model with n stocks, in which an investor faces both fixed and proportional transaction costs. The performance of an investment strategy is measured by the average return of the corresponding portfolio over an infinite time horizon....

This paper studies the concept of an international economic order, i.e. an institutional arrangement of international rules. Such rules emerge from negative experiences – historical disasters – that inflict severe hardship on people. A taxonomy for rules reducing transaction costs is...

This paper analyzes how international rules are established and stabilized, i.e. how an international institutional order develops. Rules emerge mainly through learning from negative experience and serve to reduce transaction costs. The paper looks at mechanisms that stabilize rule systems, at...

Guasoni (2006) introduced a simple condition for the absence of arbitrage opportunities. In this note we show that his results remain valid under a weaker notion of arbitrage which arises by excluding liquidation costs from the value process of a portfolio.

The paper analyses sectoral patterns of intra-Asian trade for selected Asian countries as well as for sub-regions within Asia. Beyond a general trend towards manufactures, it reveals remarkable differences in specialisation profiles between lagging South Asian countries still concentrating on...

Based on the aggregation of individual willingness-to-pay for a statistical life, we calibrate an intertemporal optimization model to determine the aggregate welfare losses from HIV/AIDS in 25 Eastern European countries. Assuming a discount rate of three percent, we find a total welfare loss for...

The aim of the study is to quantify climate induced health risks for Germany. Based on high resolution climate scenarios for the period 2071 to 2100 we forecast the number of days with heat load and cold stress. The heat frequency and intensity increases overall but more in the south. Referring...
