The concept of cointegration (see e.g., Engle and Granger, 1987; Johansen, 1988) has extensively been used to model equilibrium relationships (see e.g., Johansen and Juselius, 1990; Ericsson, 1998). The links between economic and econometric concepts are now well understood and they have become part of...

Volk und Stände der Schweiz beschlossen 2001, den absoluten Schuldenstand des Staates im Konjunkturverlauf zu begrenzen. Damit hat die Eidgenossenschaft einen Weg eingeschlagen, der sich von dem der Mitglieder des europäischen Stabilitätspaktes unterscheidet. Diese halten eine positive...

We investigate how firms' market power affects the price level. In our small macro-model we show, that firms - in addition to hypothesised structural mark-up pricing power - may take advantage of favourable business cycle fluctuations. The paper provides empirical evidence for both these...

Growth regression economics are haunted by the fact that results are easily overthrown by regressing alternative model specifications. Recent research therefore aims at obtaining robust regression results by systematically running multiple models and picking surviving variables. This note shows...

Economists and econometricians very often work with data which has been temporally disaggregated prior to use. Hence, the quality of the disaggregation clearly affects the quality of the analyses. Building on Chow and Lin's (1971) disaggregation model this paper proposes a new estimation...

The conditions under which European monetary policy is likely to be conducted are investigated by means of multi-variate time series modelling using aggregated data of all eleven European Monetary Union member states. A cointegration analysis identifies two stable long-run relationships within a...

The former German chancellor Helmut Schmidt holds that despite the huge transfers from West to East Germany the East German economy does not take off as it was widely expected. We argue it is not despite these transfers but because of them. Building on the common features of the extension of the...
