In a general equilibrium model with at least three goods, a perfectly price-discriminating monopoly (PDM) selects an inefficient production plan even if consumers are homogenous, their preferences are representable by quasi-linear utilities, and their characteristics are known to the monopolist....

In this paper, the evolution of Chinese exchange rate regime is reviewed and the effect of the union of exchange rates of yuan on the foreign trade and capital is analyzed by investigating historical data

Spanish abstract: En este artículo sometimos a escrutinio el concepto de “racionalidad”, como ejercicio de la razón. Conforme avanzamos en la investigación quedó claro que esa razón está fundada en un conjunto de valores y principios que le dan validez como decisiones correctas a...

We study an equilibrium-based continuous asset pricing problem for the securities market. In the previous work [16], we have shown that a certain price process, which is given by the solution to a forward backward stochastic differential equation of conditional McKean-Vlasov type, asymptotically...

We investigate whether US households possess advance information about their future income and what this means for consumption insurance. Based on insights from a theoretical model, we propose a new test to detect advance information, which requires only panel data on consumption and income....

Dieser Artikel erläutert die Grundzüge einer ordonomischen Wirtschaftsethik sowie einer in diesen Theorierahmen eingepassten ordonomischen Unternehmensethik. Gestützt auf diesen integrativen Ansatz werden sodann drei Management-Kompetenzen identifiziert, die eine akademische Ausbildung für...

Unternehmen sollten auf Gewinnmaximierung verzichten, um Gewinne maximieren zu können. So lautet die paradoxe Anforderung, mit der Personen konfrontiert sind, die Unternehmen im System der Wirtschaft einer modernen Gesellschaft führen. Diesem Paradoxon kommt man durch die Rekonstruktion der...

We examine aggregation in the neoclassical growth model with aggregate shocks and uninsurable employment risk, as well as related environments. We introduce a Walrasian auctioneer whose job is to report to households all possible state-contingent future prices. Households take these as given...

This paper develops a simulation-based solution method to solve large state space macrofinance models using machine learning. We use a neural network (NN) to approximate the expectations in the optimality conditions in the spirit of the stochastic parameterized expectations algorithm (PEA)....

We consider a multi-state, general-equilibrium model with collateralized financial promises to study how allowing an asset to back multiple financial contracts (i.e., tranching) affects price bases. A basis emerges when one asset can be tranched to issue more derivative securities than can be...
