Recent empirical evidence seems to show that temporary migration is a widespread phenomenon, especially among highly skilled workers who return to their countries of origin when these begin to grow. This paper develops a simple, tractable overlapping generations model that provides a rationale...

We develop a model that incorporates salient features of growth in modern economies. We combine the expanding-variety growth model through horizontal innovations with a hierarchy of basic and applied research. The former extends the knowledge base, while the latter commercializes it. Two-way...

With credence goods consumers cannot judge the quality they receive compared to the quality they need. The needed quality can only be observed by an expert seller who may exploit the information asymmetry by cheating. In recent years various contributions have analyzed the credence goods problem...

In an evolutionary sender–receiver game that describes how signals become associated with objects (Hurford, 1989; Nowak and Krakauer, 1999), the set of evolutionarily stable states coincides with the set of strict Nash strategies—and a language is a strict Nash strategy if and only if it links...

The impact of trade integration of Central and Eastern European economies in European markets has been studied extensively. Often these studies observe quality upgrading of CEEC exports. In this paper we consider three dimensions of quality upgrading: upgrading across industries, upgrading...
