In this paper, an Integer Programming (IP) model is presented to assign MBA and undergraduate students to groups to solve an exam case in an “Operations Research (O.R.)” course. It is assumed that the students have a basic understanding of mathematical programming, and are now ready to build...

This paper examines optimal redistribution in a model with high and low-skilled individuals with heterogeneous tastes for labor, that either work or not. With such double heterogeneity, traditional Welfarist criteria including Utilitarianism fail to take the compensation-responsibility trade-off...

We consider the problem of scheduling a number of jobs, each job having a release time, a processing time and a due date, on a single machine with the objective of minimizing the maximum lateness or tardiness. This problem often occurs as a sub-problem in solving other scheduling environments...

In this paper we analyze the convergence of interest rates in the European Monetary System (EMS) in a framework of changing persistence. This allows us to estimate the exact date of full convergence from the data. A change in persistence means that a time series switches from stationarity to...

Nonprofit organizations worldwide are confronted with an increasing demand for accountability and improved financial transparency. Financial reporting by nonprofit organizations is no longer an exception, it has become a rule. The usefulness of a financial report to an organization’s...

This paper reports on a new solution approach for the well-known multi-mode resource-constrained project scheduling problem (MMRCPSP). This problem type aims at the selection of a single activity mode from a set of available modes in order to construct a precedence and a (renewable and...

We estimate monetary policy rules for six central and eastern European countries (CEEC) during the period, when they prepared for membership to the EU and monetary union. By taking changes in the policy settings explicitly into account and by introducing several new methodological features we...

Governments have increasingly become involved in stimulating cooperation for innovation and R&D and have less focused on direct R&D subsidies. One set of initiatives is targeted at providing financial support for technology intermediaries. In this paper, we shed light on when technology...

Nowadays, companies are investing in a well-considered CRM strategy. One of the cornerstones in CRM is customer churn prediction, where one tries to predict whether or not a customer will leave the company. This study focuses on how to better support marketing decision makers in identifying...

This paper characterises optimal short-run monetary policy in an economy with monopolistic competition, endogenous firm entry, a cash-in-advance constraint and preset wages. Firms must make profits to cover entry costs; thus the markup on goods prices is efficient. However, a distortion results...
