In this paper we want to discuss macroscopic and microscopic properties of financial markets. By analyzing quantitatively a database consisting of 13 minute per minute recorded financial time series, we identify some macroscopic statistical properties of the corresponding markets, with a special...

Due to its high resource use and negative impacts on the environment (e.g. climate effects and land-use intensity) the production of animal-based food products is increasingly criticized. Moreover, high consumption of meat is linked with negative impacts on consumer health. In light of these...

Die deutsche Land- und Ernährungswirtschaft ist zunehmend im Fokus der öffentlichen Diskussion. Dabei bewegt sie sich in einem Spannungsfeld von marktlichen Anforderungen und gesellschaftlichen Erwartungen. Um Rückschlüsse auf das generelle Meinungsklima zu gewinnen, wird in dieser Arbeit...

We analyze the effect of IMF programs on economic agents' expectations about the economy in transitional countries using survey data from the Central and Eastern Eurobarometer poll, an annual general public survey monitoring the evolution of public opinion from 1990 to 1997. Previous studies, in...

The “hollowing-out,” or “two poles” hypothesis is tested in the context of a Markov chain model of exchange rate transitions. In particular, two versions of the hypothesis—that hard pegs are an absorbing state, or that fixes and floats form a closed set, with no transitions to...

We propose a new semiparametric observation-driven volatility model where the form of the error density directly influences the volatility dynamics. This feature distinguishes our model from standard semiparametric GARCH models. The link between the estimated error density and the volatility...

We develop a new parameter stability test against the alternative of observation driven generalized autoregressive score dynamics. The new test generalizes the ARCH-LM test of Engle (1982) to settings beyond time-varying volatility and exploits any autocorrelation in the likelihood scores under...

The paper assesses estimates of term structure models for the United States. To this end, this paper first describes the mathematics underlying two types of term structure models, namely the Nelson-Siegel and Cox, Ingersoll and Ross family of models, and the estimation techniques. It then...
