Using exceptionally rich linked administrative and survey information on German welfare recipients we investigate the health effects of transitions from welfare to employment and of assignments to welfare-to-work programmes. Applying semi-parametric propensity score matching estimators we find...

Many Western economies have reformed their welfare systems with the aim of activating welfare recipients by increasing welfare-to-work programmes and job search enforcement. We evaluate the three most important German welfare-to-work programmes implemented after a major reform in January 2005...

We propose constructing a set of trading strategies using predicted option returns for a relatively small forecasting period of ten trading days to form profitable hold-to-expiration, equally weighted, zero-cost portfolios based on 1-month at-the-money call and put options. We use a statistical...

We report results from experimental first-price, sealed-bid, all-pay auctions for a good with a common and known value. We observe bidding strategies in groups of two and three bidders and under two extreme information conditions. As predicted by the Nash equilibrium, subjects use mixed...

Im Zentrum der Arbeit steht der Versuch, anhand von einfachen Rechenbeispielen Transparenz in die Frage der steuerlichen Auswirkungen des Bankgeheimnisses auf die internationale Staatengemeinschaft zu bringen. Diese stilisierten Beispiele können leicht verfeinert werden, um die Kalküle von...

The paper shows that structural models of the IS-LM and Mundell-Fleming variety have a lot to tell about the macroeconomics of the current global crisis. In addition to demonstrating how the emergence of risk premiums in money and capital markets may drive economies into recessions, it shows the...

In this paper it is asked whether it is meaningful to state a ‘right to work’ as a basic human right to be written down in the constitution, for example, whether working time should generally be reduced, and whether those who do not have (or find) a job should get a guaranteed minimal...

Innovative firms typically have a high growth potential, need external funds to finance investment, and rely on the key effort and know-how of inside entrepreneurs. Given the limited amount of tangible assets and the non-contractible nature of entrepreneurial effort, these firms are often...

Using Swiss data from 1983 to 2008, this paper investigates whether growth rates of the different measures of the quantity of money and or excess money can be used to forecast inflation. After a preliminary data analysis, money demand relations are specified, estimated and tested. Then,...

An affine yield curve model is estimated on daily Swiss data 2002--2009. The market price of risk is modelled in terms of proxies for uncertainty, which are estimated from interest rate options. The estimated model generates innovations in the 3-month rate that are similar to external evidence...
