This paper complements research on how love of wealth bears on key variables in a Ramsey-Cass-Koopmans growth framework. It is shown that for an optimum the social planner cannot have an excessive love of wealth. If the planner has the right love of wealth an optimum exists and implies higher...

In this paper we present a new approach to evaluate the environmental efficiency of decision making units. We propose a model that describes a two-stage process consisting of a production and an end-of-pipe abatement stage with the environmental efficiency being determined by the efficiency of...

This study presents the results of an extensive Monte Carlo experiment to compare different methods of efficiency analysis. In addition to traditional parametric-stochastic and nonparametric-deterministic methods recently developed robust nonparametric-stochastic methods are considered. The...

This paper presents a Heterogeneous Agent Model of a financial market with chartist and fundamentalist traders that exhibit bounded rationality and short-term thinking to explain the effect of under and overreaction to news. The existence of the Market Maker's finite price adjustment speed leads...

This paper takes a first step in analysing how a monetary union performs in the presence of labour market asymmetries. Differences in wage flexibility, market power and country sizes are allowed for in a setting with both country-specific and aggregate shocks. The implications of asymmetries for...

This paper proposes a simple multi-industry trade model with search frictions in the labor market. Unimpeded access to global financial markets enables capital owners to invest abroad, thereby fostering unemployment at the extensive industry margin. Whether a country benefits from FDI in terms...

Wir untersuchen den theoretischen Fall einer Ökonomie in der zwei verschiedene Ausbildungstypen in der Produktion verwendet werden. Die Arbeitskräfte sind heterogen in Hinblick auf ihre Fähigkeiten und selektieren sich durch unterschiedlich hohe Investitionen in Humankapital in einen der...

Verbindungen zwischen ähnlichen Subjekten sind ein häufig beobachtetes Phänomen. Damit solche Sortierungen in einem Suchmodell auftreten, müssen oft jedoch überraschend starke Bedingungen erfüllt sein. Diese Studie zeigt, dass ein um Signale erweitertes Suchmodell sogar vollkommene...

This paper studies how the existence of a minority culture influences the well-being of the native population and its attitude towards immigrants. In this context, I assume that multicultural interaction can be advantageous for immigrants and natives if intercultural obstacles and communication...

The basic model of the literature on self-enforcing international environmental agreements is a model of autarkic countries. We extend that model by international trade and investigate its impact on the performance of Nash coalitions and on their stability, in particular, in a general...
