Summary This paper analyzes how learning behaviors can substantially modify the outcome of competition in an oligopolistic industry facing demand uncertainty. We consider the case of a symmetric duopoly game where firms have imperfect information about market demand and learn through observing the volume of their sales. The main body of the paper consists in showing how market experimentation can explain the existence ofprice-dispersion in an oligopolistic industry. We study this phenomenon and its dynamic evolution in the context of an Hotelling duopoly model; we then extend the analysis to general demand functions and toN-firm oligopolies. We discuss some implications of the public good aspect of information about market demand. We then conclude with a few comments on what happens when the value of information in the oligopolistic industry is negative.We are very grateful to Patrick Bolton for his helpful advice. We also wish to thank Richard Caves, Anthony Creane, Jean-Jacques Laffont, Andreu Mas-Colell, Eric Maskin, Jean-Charles Rochet, Margaret Slade, John Sutton, Jean Tirole, Mike Whinston and an anonymous referee. 相似文献

近来,中心城市儿童在公共空间受到伤亡的报道越来越多。据北京的一次调查表明,“坠楼”是儿童受伤的主要原因,数量甚至多于交通事故。其原由是学校、公园、住宅小区关闭了玩乐场所,交通和停车把儿童从原本属于他们的玩乐空间挤压出去。 相似文献

(a) the impact of schooling on farm earnings through the “direct” and “allocative” effects of human capital; 2.
(b) the household demand for children's schooling; 3.
(c) using macro-level data, the association between children's school-participation and some policy variables.

Default Risk in Equity Returns 总被引:17,自引:0,他引:17
This is the first study that uses Merton's (1974) option pricing model to compute default measures for individual firms and assess the effect of default risk on equity returns. The size effect is a default effect, and this is also largely true for the book‐to‐market (BM) effect. Both exist only in segments of the market with high default risk. Default risk is systematic risk. The Fama–French (FF) factors SMB and HML contain some default‐related information, but this is not the main reason that the FF model can explain the cross section of equity returns. 相似文献

How past becomes prologue: a sensemaking interpretation of the hindsight-foresight relationship given the circumstances of crisis 总被引:1,自引:0,他引:1
Maria L Nathan 《Futures》2004,36(2):181-199
Foresight is rooted in deep understanding [A.N. Whitehead. Lecture notes from address to the Harvard Business School, 1931]. Such understanding requires that we shall have first looked back to the past before venturing forward into the future. This paper uses Weick’s and colleagues’ sense making perspective in order to explore this critical relationship between the past and the future [[2], [3], [4], [5], [6] and [7]]. In particular, key sense making properties will be applied to a crisis, an occurrence of school-place violence that occurred in the United States in 1999. We shall then ask how this organization and its diverse external stakeholders used their understanding of this event to learn how to prevent such crises from occurring in the future. In other words, how capably was hindsight constructed and then how was it used to strengthen foresight into the future? This paper will conduct a theory-based empirical examination of a crisis event and its aftermath to understand how hindsight can be sharpened and then used to improve organizational foresight. 相似文献
