Efficient routines for multidimensional numerical integration are provided by quasi-Monte Carlo methods. These methods are based on evaluating the integrand at a set of representative points of the integration area. A set may be called representative if it shows a low discrepancy. However, in...

A mixed, geographically weighted regression (GWR) model is useful in the situation where certain explanatory variables influencing the response are global while others are local. Undoubtedly, how to identify these two types of the explanatory variables is essential for building such a model....

Threshold Accepting (TA) is a powerful optimization heuristic from the class of stochastic local search algorithms. It has been applied successfully to different optimization problems in statistics and econometrics, including the uniform design problem. Using the latter application as example,...

Mengenrationierungsmodelle erwiesen sich in den vergangenen Jahren als geeignete Instrumente, um Entwicklungen auf Güter- und Arbeitsmärkten zu beschreiben. Wesentliches Ingrediens dieser Modelle ist die Abkehr von der Annahme ständig preisgeräumter Märkte. Als Ursache für die Rationierung...

In econometric modelling the choice of relevant variables is of crucial importance for the Interpretation of the results. In many cases it is based on some a priori knowledge from economic theory and a rather heuristic procedure for determining other influential variables sometimes based on an...

Over the last decade credit rationing has been regarded increasingly as the outcome of asymmetric Information. Profit maximization of the banks might lead to interest rates lower than the market equilibrium rate. Administering loans at a higher interest rate to the rationed customers will...

A combinatorical problem is said to be of high computational complexity, if it can be shown that every efficient algorithm needs a high amount of resources as measured in Computing time or storage capacity. This paper will (1) introduce some basic concepts of mathematical complexity theory; (2)...

In den letzten Jahren wird die Rationierung von Krediten häufig als Ergebnis asymmetrischer Informationen zwischen Kreditgeber und -nehmer gesehen. Dabei kann es im Sinne der Gewinnmaximierung optimal sein, einen nicht markträumenden Zinssatz festzulegen. Die Vergabe von Krediten zu höheren...

Im Zuge der Analyse temporärer Ungleichgewichtssituationen wurde in den letzten Jahren auch der Kreditmarkt untersucht. Die Existenz von Kreditrationierung auf Mikromärkten wird dabei als das Ergebnis asymmetrischer Informationen zwischen Kreditgeber und -nehmer betrachtet. Dieser Aspekt wird...
