In the literature there are basically two main approaches that explain the positive link between the level of education and wages: the human-capital theory and the signalling/screening (collectively known as sorting) theory. We highlight the similarity and differences between these theories and...

In this article, we revisit the Friday the 13th effect discussed by Kolb and Rodriguez (1987) that has received increased interest in recent research. Using a dummy-augmented GARCH model, we investigate whether the occurrence of this superstitious calendar day has significant impact on the...

Fiscal positions of African countries have improved significantly during the past decade. Higher economic growth, better terms of trade, improved donor support notably through debt relief and better control of expenditure contributed to this improvement. But at the same time government revenue...

We examine the economic and social determinants of suicide mortality in a panel of 25 OECD countries over the period 1970 - 2011 and explicitly analyze the effects of unemployment and labor market institutions on suicide rates. In line with a large body of literature, our results suggest that...

This paper deals with the effects of labour market institutions on unemployment in a panel of 19 OECD countries for the period 1960 to 2000.

Ein wichtiger Erklärungsfaktor für die Entwicklung der Arbeitslosenquote sind die Institutionen des Arbeitsmarktes. Diese Arbeit zeigt empirische Ergebnisse für verschiedene Paneldaten-Modelle. Gegenüber der bisherigen Literatur unterscheidet sich der Ansatz durch drei Aspekte: 1) Wir...

This paper presents a micro data approach to the identification of credit crunches. Using a survey among German firms which regularly queries the firms' assessment of the current willingness of banks to extend credit we estimate the probability of a restrictive credit supply policy by time...

Wir analysieren die Determinanten der Zuschauernachfrage in der Fußballbundesliga in den Saisonen 2001/02 bis 2004/05, d.h. für insgesamt 1224 Spiele. Dafür spezifizieren wir ein ökonometrisches Modell, das die begrenzte Kapazität der Stadien und Heteroskedastizität berücksichtigt. Es...

This paper analyzes empirically the effects of innovation on employment at the firm level using a uniquely long panel dataset of German manufacturing firms. The overall effect of innovations on employment often remains unclear in theoretical contributions due to reverse effects. We distinguish...

Neben den klassischen Performancemaßen, wie der Sharpe-Ratio, der Treynor-Ratio und dem Jensen-Alpha wurden in den letzten Jahrzehnten weiterführende Ansätze für die Analyse und Bewertung von Kapitalanlagen entwickelt. Die moderneren Performancemaße verlangen keine Konstanz der Risikomaße...
