Widespread concern over real effects of EMU is consistent with new Keynesian approaches to macroeconomic fluctuations, but more difficult to reconcile with a real business cycle (RBC) paradigm. Using a model with frictions as a point of departure, I argue that nominal price rigidity in Europe is...

Spreadsheets are an ubiquitous program category, and we will discuss their use in statistics and statistics education on various levels, ranging from very basic examples to extremely powerful methods. Since the spreadsheet paradigm is very familiar to many potential users, using it as the...

Stochastic Delay Differential Equations (SDDE) are Stochastic Functional Differential Equations with important applications. It is of interest to characterize the L2-stability (stability of second moments) of solutions of SDDE. For the class of linear, scalar SDDE we can show that second...

According to the Sharpe-Lintner capital asset pricing model, expected rates of return on individual stocks differ only because of their different levels of non-diversifiable risk (beta). However, Fama/French (1992) show that the two variables size and book-to-market ratio capture the...

In a single index Poisson regression model with unknown link function, the index parameter can be root-n consistently estimated by the method of pseudo maximumum likelihood. In this paper, we study, by simulation arguments, the practical validity of the asymptotic behavior of the pseudo maximum...

In this paper we present an experiment on the false consensus effect. Unlike previous experiments, we provide monetary incentives for revealing the actual estimation of others' behavior. In each session and round sixteen subjects make a choice between two options simultaneously. Then they...

We consider a diffusion model of small variable type with positive drift density varying in a nonparametric set. We investigate Gaussian and Poisson approximations to this model. In the sense of asymptotic equivalence of experiments, it is shown that observation of the diffusion process until...

Parallel platforms have become widely available. Moderately priced commodity SMPs are now manufactured by most major hardware vendors. Platform independent software environments, emphasizing a transparent programming model for building distributed applications, are rapidly emerging. In this...

Since the age of Gutenberg, publishing has meant to print a book readable by a person. Of course, interaction and dynamic illustration were not possible with this media. Even during the electronic age (till the mid of the nineties), publishing had not changed much. Although media, like diskettes...

We model aggregate credit losses on large portfolios of financial positions contracted with firms subject to both cyclical default correlation and direct default contagion processes. Cyclical correlation is due to the dependence of firms on common (macro-) economic factors; credit contagion...
