Abstract. We investigate the nature of trading and sorting induced by the dynamic price mechanism in a competitive durable good market with adverse selection and exogenous entry of traders over time. The model is a dynamic version of Akerlof (1970) . Identical cohorts of durable goods, whose quality is known only to potential sellers, enter the market over time. We show that there exists a cyclical equilibrium where all goods are traded within a finite number of periods after entry. Market failure is reflected in the length of waiting time before trade. The model also provides an explanation of market fluctuations. JEL classification: D82 A propos des marchés de biens durables quand il y a entrée de nouveaux commerçants et sélection adverse. Les auteurs analysent la nature du commerce et du triage engendrés par le mécanisme dynamique des prix dans un marché concurrentiel de biens durables quand il y a sélection adverse et entrée exogène de nouveaux commerçants dans le temps. Ce modèle est une version dynamique du modèle d’ Akerlof (1970) . Des cohortes identiques de biens durables, dont la qualité est connue seulement des vendeurs potentiels, arrivent sur le marché dans le temps. Il semble qu’il y ait plus de commerce actif que ce qui est prévu par un modèle statique. En particulier, on montre qu’il existe un équilibre cyclique où tous les biens sont transigés à l’intérieur d’un nombre fini de périodes après leur arrivage et que, à chaque phase du cycle, l’éventail de qualité des biens transigés s’accroît. Les commerçants qui transigent des produits de plus haute qualité attendent plus longtemps et l’imperfection du marché se traduit par la longueur de temps d’attente avant la transaction. Le modèle fournit aussi une explication des fluctuations du marché. 相似文献

Entrepreneurship and Unemployment in the UK 总被引:1,自引:0,他引:1

The influence of industrial structure, more specifically of entrepreneurship, is investigated on the level of unemployment in the UK. The question is to what extent entrepreneurship, i.e., business ownership can reduce the level of unemployment. The alleged differences between the managed and the entrepreneurial economy will be discussed as well as the links between entrepreneurship and unemployment. It will be concluded that the UK is a relative outlier when using a simple model of the relationship between unemployment and the rate of business ownership. The model is calibrated using recent data of some 23 OECD countries. It underestimates the decrease in unemployment in the UK in the period 1982–1990. Some arguments are brought forward why this might be the case. 相似文献

We model a two-period pure exchange economy where a risk averse manager, who has private information regarding future earnings, is required to issue an earnings report to investors at the end of each period. While the manager is prohibited from directly disclosing her private information, she is allowed to bias reported earnings in the first period, subject to GAAP rules that require that a specified proportion of the bias be reversed subsequently. We show there is a minimum threshold of reversal, such that, when the proportion of required reversal is above this threshold, the manager smooths income and communicates her private information through reported earnings. Consequently, the market attaches greater weight to reported earnings than under a regime that allows no discretion. When the required reversal is below the minimum threshold, the manager increases reported earnings without limit and the equilibrium degenerates. When the manager is not endowed with any private information, the market unravels the "true" earnings and price is unaffected by earnings management. Our results underscore the importance of both allowing and restricting reporting discretion through formal mechanisms. 相似文献

This paper is an expository introduction to several topics of current research in the general equilibrium theory of rational expectations. More specifically, we discuss the existence of exact and approximate rational expectations equilibria, the implementation of equilibria, the behavior of learning and smoothing processes by which traders construct expectations from repeated observations of the market, and the lagged use of the information revealed by prices in an intertemporal sequence of markets. The purpose of this discussion is to introduce papers on these topics appearing in the Journal of Economic Theory Symposium on Rational Expectations in Microeconomic Models. 相似文献

Abstract . An empirical analysis of the property crimes, robbery, burglary and larceny, is presented for all 120 counties in Kentucky. While this analysis is based on an economic model of crime, certain sociological and legal variables are included as well in the system of equations. Overall, the empirical results support prior studies’findings with the exception that a quadratic relationship is found to exist between urbanization and each of the property crimes. Furthermore, neither the economic nor the non economic influences measured appear more important for affecting crime rates. Specifically, results indicate that the level of poverty, the degree of tourism, the presence of police, the unemployment rate and the apprehension rate all affect property crimes. In contrast, the length of sentence, the degree of industrialization, the level of public assistance payments and the proportion of youth in the county have no affect on property crime rates in these areas. 相似文献

Summary. We consider a Bertrand duopoly model with increasing returns to scale where one of the firms have a cost advantage and prices
vary over a grid. We find that typically more than one equilibria exist. However, there are only two perfect equilibria. Moreover,
as the size of the grid becomes small, both these equilibria converge to the limit-pricing outcome.
