This paper is concerned with the study of the labor market performance of immigrants. The unemployment rate is used as an indicator and natives as the reference group for the analysis. The analysis proceeds in two steps. In a first step, probit regressions on the unemployment probabilities are...

This paper proves that the Mortensen-Pissarides matching theory is nothing but a tautology. They started with an assumption and ended with the same as solution. Their assumption/solution is also at odds with the Beveridge, or the negative vacancy-unemployment relation

Many recent reforms raise the age of retirement. But can all older individuals work longer? To answer that question this paper uses the European SHARE survey. Results are essentially fivefold. First, physical health and cognitive performance deteriorate with age. Second, the 50-54 employment...

The cost of old-age dependency leads to reforms aimed at raising the age or retirement. But do older individuals have the health/cognitive capacity to work longer? This paper asks how much older individuals (55-75) could work if they worked as much as their younger (50-54) counterparts in...

Publication and citation rankings have become major indicators of the scientific worth of universities and countries, and determine to a large extent the career of individual scholars. We argue that such rankings do not effectively measure research quality, which should be the essence of...

The objective of evaluating public policy measures is to assess its implications and thus to obtain a measure for weather the respective program has been successful. In this paper, we consider and classify microeconomic and microeconometric approaches to measuring this success. To do so, the...
