For a long time, migration has been subject to intensive economic research. Nevertheless, empirical evidence regarding the determinants of migration still appears to be incomplete. In this paper, we analyze the effects of socio-economic and institutional determinants, especially labor-market...

In this paper, we quantitatively assess the welfare implications of alternative public education spending rules. To this end, we employ a dynamic stochastic general equilibrium model in which human capital externalities and public education expenditures, financed by distorting taxes, enhance the...

This article takes issue with a recent book by Ziliak and McCloskey (2008) of the same title. Ziliak and McCloskey argue that statistical significance testing is a barrier rather than a booster for empirical research in many fields and should therefore be abandoned altogether. The present...

In this paper we propose a novel way to model the labor market in the context of a New-Keynesian general equilibrium model, incorporating labor market frictions in the form of hiring and firing costs. We show that such a model is able to replicate many important stylized facts of the business...

Optimal nonanticipating controls are shown to exist in nonautonomous piecewise deterministic control problems with hard terminal restrictions. The assumptions needed are completely analogous to those needed to obtain optimal controls in deterministic control problems. The proof is based on...

The present paper is constituted around the idea of EU sustainable convergence in higher education in the context of Bologna process. Considering the Systems Theory and by using causal loops diagrams, it is brought forth an excellence model whose implementation facilitates the sustainable...

Es ist ein bekanntes Phänomen, dass die Anzahl der Koautoren in der Volkswirtschaftslehre in den letzten drei Jahrzehnten zugenommen hat. Der Artikel zeigt auf der Basis des bisher größten Datensatzes, dass es einen fortbleibenden Trend zu mehr Koautoren pro Artikel gibt, der wahrscheinlich...

We develop an efficient and easy-to-use computational method for solving a wide class of general equilibrium heterogeneous agent models with aggregate shocks, together with an open source suite of codes that implement our algorithms in an easy-to-use toolbox. Our method extends standard...

Vor einem Jahrzehnt wurde das Hauptgutachten des Wissenschaftlichen Beirats der Bundesregierung für Globale Umweltveränderungen (WBGU) veröffentlicht. Dieser Versuch einer Bestandsaufnahme im Jahre 2011 hat national und international Impulse gesetzt und Orientierung gegeben. Der WBGU ging...
