Die „Geprüfte Qualität – HESSEN“ (GQH) ist ein stufenübergreifendes Zertifizierungszeichen für Lebensmittel mit einem Herkunftsbezug. Der Beitrag bewertet die GQH aus Produzentensicht. Es wird untersucht, ob ein Beitrag zur Einkommenssicherung in der Agrar- und Ernährungswirtschaft...

We use data on wages and rents in different U.S. cities to assess the amenity effects on production and consumption of cultural diversity as measured by diversity of countries of birth of city residents. We show that US-born citizens living in metropolitan areas where the share of foreign-born...

We attempt to formulate and explain two types of self-fulfilling prophecy, called the Pygmalion effect (if a supervisor thinks her subordinates will succeed, they are more likely to succeed) and the Galatea effect (if a person thinks he will succeed, he is more likely to succeed). To this...

We anlyze the stochastic control approach to the dynamic maximization of the robust utility of consumption and investment. The robust utility functionals are defined in terms of logarithmic utility and a dynamically consisten convex risk measure. The underlying market is modeled by a diffusion...

In economic theory, utility depends on past, present and future outcomes. The experiment described in this paper suggests that utility also depends on people's attitudes, and that it can easily be manipulated through these attitudes. The results imply, first, that purely outcome-based models of...

This article discusses the limitations of the orthodox economic theory of the firm as a nexus of contracts. Various experimental studies have shown that the aggregation of individuals in groups changes behavior and preferences systematically. This perspective has been formalized by models of...

This paper argues that the consumption value of education is an important motivation for the educational choice. While controlling for ability, we document that individuals are willing to forego substantial future wage returns in order to acquire a particular type of higher education. We...

The concept of utility is often used in ambiguous ways in economics, from having substantive psychological connotations to being a formal placeholder representing a person's preferences. In the accounts of the early utilitarians, it was a multidimensional measure that has been condensed during...

We give an explicit PDE characterization for the solution of the problem of maximizing the utility of both terminal wealth and intertemporal consumption under model uncertainty. The underlying market model consists of a risky asset, whose volatility and long-term trend are driven by an external...
