Daß ökonomische Prozesse zu den primären evolutorischen Untersuchungsgegenständen gehören und wie alle handlungserzeugten Prozesse, die nicht antizipierte Neuheiten hervorrufen können, grundsätzlich als verlaufs- und ergebnisoffen zu konzipieren sind, ist unstrittig. Um den Problemen des...

Capital accumulation and creative destruction is modeled together with risk-averse households. The novel aspect - risk-averse households - allows to use well-known models not only for analyzing long-run growth as in the literature but also short-run fluctuations. The model remains analytically...

We analyze the spatial interaction among regions in North America and in Western Europe. We use a gravity model extended by a spatial correlation structures where data allows to evaluate the level of impact and the length of the spatial tail. This allows us to address to effects external to the...

This paper provides a simple model of corruption dynamics with the ratchet effect. Corrupt officials have ex post the incentive to price discriminate entrepreneurs based on the entry decisions made in an earlier period. The inability of government officials to commit to future money demands...

Empirical evidence suggests that many mergers do not increase profits of the participating firms and decrease welfare. Due to the globalization of markets we should take an international view on mergers and their welfare effects. This paper develops a Bertrand-model of an international...

Within the prospect theory the paper examines production and hedging decisions of a competitive firm under price uncertainty. We consider the prospect theory for the firm's utility function in the two moment model known as (mu,sigma)-preference. In contrast to the literature our findings show...

The paper examines the economic role of modelling information on the decision problem of an exporting firm under exchange rate risk and hedging. Information is described in terms of market transparency, i.e., a publicly observable signal conveys more information about the random foreign exchange...

Im vorliegenden Text wird dargelegt, warum in die moderne Wirtschaft ein Wachstumszwang und Wachstumsdrang eingebaut sind. Wird eine globale minimale Wachstumsrate unterschritten, kommt es zur Krise. -- Wachstumsspirale ; Geldsystem ; Krise

We study the economic relationship between globalization and inequality within a country. In a partial equilibrium it is shown even when the local government exclusively maximizes the welfare of the marginalized (unemployed) people, relative consumption inequality between employed and the...

This paper analyses the impact of the regional age structure on growth of German regions. Based on a neoclassical growth model an augmented Solow model was derived and estimated in a spatial econometric approach. Besides labor and human capital, public spendings and urbanisation measures are...
