Although the possibility to combine column generation and Lagrangian relaxation has been known for quite some time, it has only recently been exploited in algorithms. In this paper, we discuss ways of combining these techniques. We focus on solving the LP relaxation of the Dantzig-Wolfe master...

We describe an algorithmic approach to determine an efficient railway rolling stock circulation on a single line or on a set of interacting lines. Given the timetable and the passengers? seat demand, we develop a branch-and-price algorithm that results in an allocation of rolling stock material...

For Germany, Spain, France, the Netherlands and the US an Error Correction Model with a long-term non-linear wage equation is estimated by 3-SLS to obtain consistent estimates, accounting for endogeneity and common shocks. On the basis of the estimated parameter elasticities of wages with...

The economic development in the United States has been very successful over the past decade, with high economic growth being accompanied by relatively low inflation. This article explores this development, comparing the economy of the United States with that of the EMU. In addition, it considers...

We study the capital structure dynamics of Central and Eastern European firms in order to get a better understanding of the quantitative and qualitative development of the financial systems in this region. The dynamic model we use endogenizes the target leverage as well as the adjustment speed...

Since the mid nineties unemployment has substantially decreased in some EMU-countries. One important factor underlying this development is wage moderation. This paper investigates wage formation and wage development. Using a theoretical wage bargaining model main determinants of formation are...

This article identifies the circumstances under which the introduction of a basic income in an efficiency-wage economy leads to the desirable effects of lower unemployment, nondecreasing real incomes and profits, and an increase of secondary- versus primary-sector wages. The model analyses show...
