The Effects of Delays on the Stability and Rate of Convergence to Equilibrium of Oligopolies*

The stability of oligopolies is investigated using the Cournot strategy and a general output adjustment procedure. Information delays are incorporated in the adjustment procedure and their specific effects upon the dynamic stability of oligopolies is investigated. The stability of equilibrium for discrete models is unaffected by information delays and remoteness of planning horizons; however the rate of convergence to equilibrium may be slowed. For continuous models with delays, some restraints are required for stability.     

Inferring Transactions from Financial Statements*

In this paper, we embed the double entry accounting structure in a simple belief revision (estimation) problem. We ask the following question: Presented with a set of financial statements (and priors), what is the reader's “best guess” of the underlying transactions that generated these statements? Two properties of accounting information facilitate a particularly simple closed form solution to this estimation problem. First, accounting information is the outcome of a linear aggregation process. Second, the aggregation rule is double entry.     

EXPLOITING AN ADVANTAGE--DECLINING AN ADVANTAGE

Within the context of the study, a firm is said to have an advantageover another if it obtains more customers given they both chargethe same price. Further, consumer switching costs imply thelarger the difference in the prices charged by the two firmsthe greater the proportion of consumers who switch from thehigher-priced firm to the lower-priced one. The Nash equilibriumto the price-posting game is characterized The firm with theadvantage charges a higher price Finally, it is shown that ifone firm can freely choose to have an advantage, it will rejectit. This follows as the greater the advantage, the smaller theequilibrium profits to both firms.     

Capital Market Experience for Financial Accounting Students*

Abstract. In this paper we present an innovative teaching tool for introductory financial accounting students that promotes active learning using methods at the frontier of market research. We describe the implementation of an asset market where students assume the role of traders in order to learn the role of information in price formation. We discuss the pedagogical questions which are addressed in the design of this market, and we relate the responses to questionnaires distributed to students at the end of the quarter. When we control for prior grade point averages (GPAs) of students, we find that those who participate in the market had better classroom performance. Résumé. Les auteurs présentent ici un instrument pédagogique innovateur, à l'intention des étudiants des cours d'introduction à la comptabilité financière, favorisant l'apprentissage dynamique grâce à l'utilisation de méthodes voisinant de près l'étude de marché. Ils décrivent la mise en place d'un marché de biens où les étudiants assument les fonctions de négociateurs en vue d'apprendre quel est le rôle de l'information dans la formation des prix. Ils analysent les questions pédagogiques que soulève la conception de ce marché et font état des réponses des étudiants aux questionnaires qui leur sont distribués à la fin du trimestre. Lorsqu'ils contrôlent les notes moyennes antérieures des étudiants, les auteurs constatent que ceux qui ont participé au marché font preuve d'un rendement supérieur en classe.
