Adäquation (älterer Ausdruck: Korrespondenz) meint ganz allgemein die Übereinstimmung einer Aussage mit dem Sachverhalt. In den Wirtschaftswissenschaften geht es speziell um die statistische Adäquation von Daten und Variablen mit dem Ziel einer Minimierung des "Abstands" (der sog....

This Paper investigates the relationship between risk and productive activity and the degree of financial intermediation in a model with moral hazard. Entreprenuers can simultaneously get credit from two types of competing institutions: ‘financial intermediaries’ and ‘local lenders’. The...

I study the constrained efficient allocations of a simple model of risk sharing and capital flows across countries assuming that each country cannot commit to fully repay its contract obligations. In the model, the degree of risk sharing and the amount of investment are interdependent. It is...

This paper presents the results of a policy oriented macroeconomic experiment involving an ‘international’ economy with a relatively small ‘home’ country and a large ‘foreign’ country. It compares the economic performance of two alternative tax systems: a wage tax system and a...

Much recent research in economics focuses on exploring behavioral anomalies, i.e., systematic deviations from the assumptions of the rationally self-interested model of man. Laboratory studies are used to identify seeming inconsistencies with micro-economic theory on the level of individuals....

This paper examines the research area identified by Frey and Gallus (Aggregate Effects of Behavioral Anomalies: A New Research Area, 2014) and the relationship between it and the choices that economists make. It supports the Frey and Gallus view that, as a consequence of individuals employing...

Research rankings based on publications and citations today dominate governance of academia. Yet they have unintended side effects on individual scholars and academic institutions and can be counterproductive. They induce a substitution of the "taste for science" by a "taste for publication". We...

The paper deals with the problems of coordination between monetary and fiscal policies in the Euro area. It examines how the existing institutions handle these problems and how the literature evaluates their working, deriving from these evaluations a proposal to reorganise them. The paper points...

In a model of evolution driven by conflict between societies more powerful states have an advantage. When the influence of outsiders is small we show that this results in a tendency to hegemony. In a simple example in which institutions differ in their "exclusiveness" we find that these...
