In classification, with an increasing number of variables, the required number of observations grows drastically. In this paper we present an approach to put into effect the maximal possible variable selection, by splitting a K class classification problem into pairwise problems. The principle...

Linear Discriminant Analysis (LDA) performs well for classifica- tion of business phases – even though the premises of an LDA are not met. As the variables are highly correlated there are numerical as well as interpretational shortcomings. By transforming the classification problem to a...

In this paper an evolutionary simulation model, based on replicator dynamics, is developed. The purpose is to identify changes in the patterns of evolution of the market structure caused by Information and Communication Technologies (ICT) in the E-conomy in comparison to the Old Economy (without...

In this paper we present three simple theoretical models to explain the influence of the possibility to make non-binding announcements on future investment behaviour in public good settings. Our models build on the idea that voluntary contributions to the supply of a public good might be...

This paper analyses a RBC model in continuous time featuring deterministic incremental development of technology and stochastic fundamental inventions arriving according to a Poisson process. Other than in standard RBC models, shocks are uncorrelated, irregular and rather seldom. In two special...

In this paper we study the impact of more transparency in the interbank market on the volume of bank intermediated loans and on the profitability of the banking business. Transparency is modeled by means of the informational content of publicly observable signals correlated to the random...

Korruption ist ein globales Phänomen, das vor allem für viele Entwicklungsländer als Wachstumsbremse wirkt. Der Beitrag zeigt, wie man mittels eines einfachen industrieökonomischen Modells die Wirkungsmechanismen der Korruption analysieren kann. Korruption hält Unternehmen vom Markteintritt...

The competitive allocation of labor across different sectors of an economy may not be socially optimal when one sector uses foreign capital. We argue that a suitably designed government intervention is required to restrict the sectors to their optimal size and maximize national welfare. Such a...

International and national investors are often exposed to real wealth risks, stemming from volatile asset prices and inflation uncertainty, making it difficult to stabilize consumption patterns. However, investors can enter futures markets to hedge against these risks. The paper develops a...
