As in Roemer (1982, chapter 1), this paper considers a simple international trade model and examines the existence and characterization of free trade equilibria involving the unequal exchange of labor (UE). The paper provides an almost complete characterization of the domain of economies in...

Over the past two decades, private equity has contributed to a shrinking of the U.S. stock market. We develop a political economy model of private equity activity to study the wider economic consequences of this trend. We show that private and social incentives to delist firms from the stock...

Gruppierungs- und Reihenfolgeprobleme der Fertigung zählen zu den zentralen Fragestellungen der (operativen) Produktionsplanung. Gruppierung bezeichnet dabei die zu treffenden Entscheidungen über Größe und zeitliche Lage von Fertigungsaufträgen (Losen), während der Reihenfolgeaspekt die...

Das zunehmende Interesse an der Analyse dynamischer Prozesse und die sich ständig verbessernde Verfügbarkeit der zu ihrer Untersuchung notwenigen Datensätze lassen die Frage nach geeigneten Verfahren aufkommen. Traditionelle Methoden wie logistische und lineare Regression sind entweder nicht...

This paper addresses an airport gate assignment problem with multiple objectives. The objectives are to minimize the number of ungated flights and the total passenger walking distances or connection times as well as to maximize the total gate assignment preferences. The problem examined is an...

We build a two-country dynamic general equilibrium model to study whether European citizens would benefit from the eventual accession of Turkey to the European Union. The results of the simulations show that Turkey's accession to the European Union is welfare enhancing for Europeans, provided...

We introduce a network formation model based on the idea that individuals engage in production (or decide to participate in an action) depending on the similar actions of the people they observe in the society. We differentiate from the classical models of participation by letting individuals to...

This paper is concerned with modelling time series by single hidden layer feedforward neural network models. A coherent modelling strategy based on statistical inference is presented. Variable selection is carried out using existing techniques. The problem of selecting the number of hidden units...
