A non-linear model is applied where suddenly strong spurts of exports occur when changes of the exchange rate go beyond a zone of inaction. We call the latter a "play" area - analogous to mechanical play and implement an algorithm describing path-dependent playhysteresis into a regression...

Barriers to entry are regarded as major impediments to the working of markets. Entry must not necessarily actually take place - the perceived threat of entry may encourage incumbent firms to behave as if they are in a competitive market, even if they are not. We present empirical evidence on...

Theory predicts a positive relationship between market concentration and profitability in most scenarios. In empirical work, however, this relation is frequently not found or only a weak connection is observed. We compare the performance of concentration and market share variables, which are...

We estimate the determinants of various types of product innovation. Knowledge spillovers from rivals have a positive impact on incremental innovations. This impact is largely independent of the participation in R&D cooperations. Spillovers exert no such independent influence on drastic...

This paper analyses the monetary policy interdependence between the European Central Bank (ECB) and the Federal Reserve (Fed) for the period 1999-2006. Two models are specified: a partial Vector Error Correction Model (VECM) and a general VECM. In the partial VECM, we look for a long-run...

This paper examines the significance of different fundamental regimes by applying various monetary models of the exchange rate to one of the politically most important exchange rates, the exchange rate of the US dollar vis-à-vis the euro (the DM). We use monthly data from 1975:01 to 2007:12....

The theoretical discussion concerning the question whether the incumbent or the (potential) entrant invests more into R&D has attracted considerable interest. This paper reports the results of an empirical study on this question using data of about 3500 German firms over the years 1992 to 1995....

This paper discusses the incentives for innovation when liability is limited or not. Clearly innovative activity involves risk. On the one hand, the risk of firm owners is limited if their liability is limited. On the other hand credits will be more difficult to receive if liability is limited....
