We estimate the effects of income from various sources on charitable giving using administrative German income tax data. We demonstrate that charitable contributions are not uniformly affected by different income types. While business and capital income exhibit a positive effect, the remaining...

Optimization of international securitized real estate portfolios has been a key topic for several decades. However, most previous analysis has focused on regional diversification by applying the traditional mean-variance (MV) framework suggested by Markowitz (1952) even if the limitations of...

This paper studies how cognitive and social skills in childhood are related to the duration of unemployment in adolescence and early adulthood. I estimate a flexible proportional hazard rate model for the probability of making a transition from unemployment to employment during an individual’s...

We develop a tractable macroeconomic model with employment risk and labor market search in order evaluate the effects of labor market reform on unemployment, growth, and welfare. The model has a large number of risk-averse households who can invest in risk-free physical capital and risky human...

We analyze the effectiveness of publicly financed training and retraining programs in east Germany as measured by their effects on individual re-employment probabilities after training. These are estimated by discrete hazard rate models on the basis of individual-level panel data. We account for...

We analyze the effectiveness of public works programs (PWP, Arbeitsbeschaffungsmaßnahmen) in east Germany as measured by their effects on individual future reemployment probabilities in regular jobs. These are estimated by discrete hazard rate models on the basis of individual-level panel data....

We estimate the employment effects of training, intervention works (subsidised employment), and public works programmes in Poland. The analysis is based on retrospective monthly calendar information on the labour force state and active labour market programme (ALMP) participation between January...

We analyse Polish active labour market policy (ALMP) training programmes from a macroeconomic (regional) point of view. The effects of training programmes on the outflows from unemployment and the effects of all ALMP programmes on the outflows from employment (to identify displacement effects)...

We present a new and simple empirical methodology to identify relative wage rigidity dynamics. The methodology is applied to data from the Polish Labour Force Survey for the period 1994 to 1998. We estimate ceteris paribus changes in relative wage and unemployment differentials for various...
