Common approaches to test for the economic value of directional forecasts are based on the classical Chi-square test for independence, Fisher’s exact test or the Pesaran and Timmerman (1992) test for market timing. These tests are asymptotically valid for serially independent observations....

According to the German disability law, or Schwerbehindertengesetz, either six percent of all jobs in an establishment must be occupied by bisabled employees or the firm has to pay a penalty of DM 200 per month for every job under consideration. This note reports results from the first...

Using a large panel data set we investigate whether works councils act as a sand or grease in the operation of German firms. Stochastic production frontier analysis indicates that establishments with and without a works council do not exhibit significant differences in efficiency

A huge body of empirical and theoretical literature has emerged on the relationship between foreign exchange (FX) uncertainty and international trade. Empirical findings about the impact of FX uncertainty on trade figures are at best weak and often ambiguous with respect to its direction. Almost...

In this study we forecast the term structure of FIBOR/EURIBOR swap rates by means of recursive vector autoregressive (VAR) models. In advance, a principal components analysis (PCA) is adopted to reduce the dimensionality of the term structure. To evaluate ex-ante forecasting performance for...

It is commonly accepted that information is helpful if it can be exploited to improve a decision making process. In economics, decisions are often based on forecasts of up- or downward movements of the variable of interest. We point out that directional forecasts can provide a useful framework...

Das Schwerbehindertengesetz verpflichtete in seiner bis 30.9.2000 gültigen Fassung alle Arbeitgeber ab 16 Beschäftigten, sechs Prozent der Arbeitsplätze mit Schwerbehinderten zu besetzen, ansonsten war für jeden nicht entsprechend besetzten Arbeitsplatz eine Ausgleichsabgabe von monatlich...

German law guaranteeing works councils is not a datum. The thrust of legislation has changed significatly on a number of occasions since 1920. The most recent legal change in the form of the Works Constitution Reform Act marks a controversial swing in favor of works council formation and...

Research in wage differentials has a long tradition. Prominent reasons why people make more or less money in the labor market include personal characteristics of the employee (e.g., human capital or gender), job characteristics (working conditions demanding compensating wage differentials), and...

In a sharp break with past German research, some recent estimates have suggested that plants with work councils have 25 to 30 per cent higher productivity than their works-council-free counterparts. Such findings can only serve to buttress the strong theoretical and policy interest in the German...
