This paper uses the European Monetary Union (EMU) as a natural experiment to investigate whether more effective monetary policy reduces the persistence of inflation. Taking into account the fractional integration of inflation, we confirm that inflation dynamics differed considerably across Euro...

Während direkte Immobilieninvestments lang Zeit als renditeträchtig bei gleichzeitig begrenztem Risiko galten, führte den Anlegern insbesondere die gegenwärtige Finanzmarktkrise vor Augen, dass auch Immobilienanlagen insbesondere in den USamerikanischen Häusermarkt mit hohen Risiken...

A novel simulation based approach to unit root testing is proposed in this paper. The test is constructed from the distinct orders in probability of the OLS parameter estimates obtained from a spurious and an unbalanced regression, respectively. While the parameter estimate from a regression of...

In der Wertschöpfung der türkischen Landwirtschaft hat die Obst- und Gemüseproduktion große Bedeutung und Tafel- und Industrietomaten sind wiederum das wichtigste Einzelprodukt unter den Gemüsesorten. Das Papier beschreibt die Struktur und Entwicklung des Sektors seit den 1990-er Jahren und...

Reliable marketing opportunities in both interregional and international trade along with relatively low transportation [and transaction] costs are essential to profitability of wheat production. In this study we have investigated one aspect of the quality of marketing and trade opportunities in...

We use an information-theoretic approach to interpret Engle's (1982) and Bollerslev's (1986) GARCH model as a model for the motion in time of the expected conditional second power moment. This interpretation is used to show how these models may be generalized, if we use alternative measures of...

Information-theoretic approaches still play a minor role in financial market analysis. Nonetheless, there have been two very similar approaches evolving during the last years, one in so-called econophysics and the other in econometrics. Both generalize the notion of GARCH processes in an...

A generalization of the hyperbolic secant distribution which allows both for skewness and for leptokurtosis was given by Morris (1982). Recently, Vaughan (2002) proposed another flexible generalization of the hyperbolic secant distribution which has a lot of nice properties but is not able to...

With the celebrated model of Black and Scholes in 1973 the development of modern option pricing models started. One of the assumptions of the Black and Scholes model is that the risky asset evolves according to a geometric Brownian motion which implies normally distributed log-returns. As...

Credit risk measurement and management become more important in all financial institutions in the light of the current financial crisis and the global recession. This particularly applies to most of the complex structured financing forms whose risk cannot be quantified with com-mon rating...
