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
Roy Thurik 《Scottish journal of political economy》2003,50(3):264-290
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

The quality and effectiveness of marketing strategy: Effects of functional and dysfunctional conflict in intraorganizational relationships 总被引:1,自引:0,他引:1
Anil Menon Sundar G. Bharadwaj Roy Howell 《Journal of the Academy of Marketing Science》1996,24(4):299-313
By examining only dysfunctional conflict and ignoring functional conflict, empirical research in marketing has presented only
part of the story. This research offers the first systematic look at the antecedents and consequences of both functionaland dysfunctional conflict in intraorganiational relationships. The authors develop and empirically test a causal model for key
organizational antecedents of new product strategy quality and market performance. They find that dysfunctional conflict in
the decision-making process has deleterious consequences for quality of strategy and market performance, whereas functional
conflict improves both quality of strategy and performance. Specifically, organizational design characteristics such as formalization,
interdepartmental interconnectedness, low communication barriers, and team spirit improve new product performance by enhancing
functional conflict, whereas centralization and high communication barriers lower new product performance by increasing dysfunctional
conflict. A post hoc test for common method bias or variance suggests that bias or variance alone cannot explain these findings.

Synopsis We describe the first effort at creating a global ex-vessel fish price database, which is required for understanding the economic
behavior of participants in the world’s fisheries. We demonstrate potential applications of the database by linking it to
a spatially defined catch database, which makes it possible to attach landed values to species in both time and space. This
is the first database available publicly where interested members of the public, researchers and managers can easily find
and access ex-vessel prices of the world’s major commercial fish species. Preliminary results indicate that the average real
price of a number of species have declined between 1950 and 2002. The estimated landed value of fish globally, in year 2000
dollars, was about US$24 billion in 1950. It increased steadily to about US$90 billion in the early 1970s, reached a peak
of US$100 billion at the end of the 1980s, and declined to about US$80 billion in 2000. The top 15 fishing countries cumulatively
account for 79% of total real landed value, with Japan leading, even though the value of its landings has been declining.

The determination of interconnection charges to essential facilities is an important problem in regulated telecommunications markets in the wake of the Telecommunications Act of 1996. This paper defines mathematical conditions for the essentiality of upstream productive inputs and examines their implications for efficient interconnection pricing. The paper shows conditions under which the efficient component-pricing rule (ECPR) can be derived as a special case of a Ramsey pricing rule. The paper also shows how efficient pricing differs from the ECPR for a number of interesting cases. 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
