In dieser Arbeit wird die Entwicklung der intersektoralen Lohnstruktur in der BRD untersucht. Als Ziel weiterer Arbeiten steht dabei auch die Erklärung des Mismatchparameters für den Arbeitsmarkt in Mengenrationierungsmodellen im Hintergrund. Hier wird zunächst axiomatisch ein Dispersionsmaß...

This paper attempts to evaluate the impact of current and future immigration flows on major macroeconomic variables of the West German economy. The analysis is based on a macroeconometric disequilibrium model for the West German economy. This model is extended until 1995 and used for several...

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...

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)...

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...

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...

This paper attempts to evaluate economic effects of migration into Germany on the basis of a macroeconometric disequilibrium model. Germany has the advantage of having experience with migratory movements of guestworkers. There was a tremendous infiow of those workers in the sixties as well as an...

Not all markets are always characterized by immediate market clearing, for example due to a delayed adjustment of quantities and prices. Macroeconometric disequilbrium models proved to be a valuable tool in assessing the relevance of such phenomena on goods and labour markets. Asymmetric...

The closing of tax loopholes is one important instrument for fiscal consolidation. We concentrate on the value added tax exemption of banking services in Germany. The potential tax revenue under full value added taxation cannot be estimated from national accounting data, as it is necessary to...

Asymmetric information between lender and borrower is made responsible for financing constraints at the firm level which may influence real activity. In this paper a standard model of credit rationing due to adverse selection and adverse incentive effects is used to derive hypotheses on causes...
