This paper offers a resolution to an extensively studied question in theoretical economics: which measure spaces are suitable for modeling many economic agents? We propose the condition of 'nowhere equivalence' to characterize those measure spaces that can be effectively used to model the space...

Behavioral economics aspires to replace the agents of neoclassical economics with living, breathing human beings. Here, the author argues that behavioral economics, like its neoclassical counterpart, often neglects the role of active sense-making that motivates and guides much human behavior....

Consider the problem of maximizing the revenue from selling a number of goods to a single buyer. We show that, unlike the case of one good, when the buyer's values for the goods increase the seller's maximal revenue may well decrease. We then identify two circumstances where monotonicity does...

We characterize a class of dynamic stochastic games that we call separable dynamic games with noisy transitions and establish that these widely used models are protocol invariant provided that periods are sufficiently short. Protocol invariance means that the set of Markov perfect equilibria is...

This paper presents a general model of a competitive market with consumption externalities, and establishes the existence of equilibrium in the model, under assumptions comparable to those in classical models. The model allows production and indivisible goods. Examples illustrate the generality...

Aim: There exists an inequilibrium between the available quantity of goods and the level of consumption resulting in local economic polarisations and asymmetric capital concentrations. Replacements of real money with derivative instruments cause strong perturbations on capital markets. Consumer...

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...

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....

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...

The present paper explores the possibility of forecasting company liquidity based on testing the coefficient of variability. Secondly, it analyzes static and dynamic liquidity measures to ascertain which are better at prediction in the traditional and technology-based sectors. It was assumed...
