Die Interpretation des Zinssatzes als Preis ist problematisch. Im Gegensatz zum Preis ist der Zinssatz kein Austauschverhältnis. Modelle, in denen der Zinssatz mit einem Preis für die Nutzung von Kapital identifiziert werden kann, sind sehr speziell. In allgemeineren Modellen sind Zinssatz und...

In a paper delivered at the December 1955 meeting of the Econometric Society, Paul Samuelson noted that though economists had done "work of high quality and great quantity in the field of taxation," the theory of public expenditure had been "relatively neglected" (1958, 332). Anglo-American...

We propose a model of "trade" between high income and low-income groups where the rich being scared of the spread of infection hires the poor to engage them in exposure-intensive outdoor activities as workers in the household industry. People who endure hardships and sustain exposure to...

Die gegenwärtigen Kontroversen zu den Auswirkungen eines Energieembargos gegen Russland, ausgelöst durch Russlands Krieg gegen die Ukraine, haben den Fokus auf die Verringerung der Abhängigkeit von fossilen Energieträgern und eine Neuordnung der Energieversorgung gelegt....

Fabio Petri's Microeconomics for the Critical Mind (2021) is an impressive tour de force in the field of microeconomic theory. It manifests the author's command of cutting edge analytical tools, concepts, and theoretical approaches both in the mainstream and in the heterodox literature. The book...

We propose a theory of how market power affects wage inequality. We ask how goods and labor market power jointly affect the level of wages, the Skill Premium, and wage inequality. We then use detailed microdata from the US Census between 1997 and 2016 to estimate the parameters of labor supply,...

We present an integrated market model which considers the dependencies between the wholesale market and the highly regulated balancing power markets. This fosters the understanding of the mechanisms of these markets and, thus, allows the evaluation of the designs of these markets and their...

A stumbling block in the modelling of competitive markets with commodity and price spaces of infinite dimensions, arises from having positive cones with an empty interior. This issue precludes the use of tools of differential analysis, ranging from the definition of a derivative, to the use of...

There is a general presumption that social preferences can be ignored if markets are competitive. Market experiments (Smith 1962) and recent theoretical results (Dufwenberg et al. 2008) suggest that competition forces people to behave as if they were purely self-interested. We qualify this view....

To design an optimal education policy, it is essential to account for the fertility differential between the poor and the rich because it affects the human capital investment through the child quantity-quality tradeoff of children. We develop a dynamic general equilibrium in which parents choose...
