This article explores the application of oblivious equilibrium (OE) to highly concentrated markets. We define a natural extended notion of OE, called partially oblivious equilibrium (POE), that allows for there to be a set of strategically important firms (the “dominant” firms), whose firm states are always monitored by every other firm in the market. We perform computational experiments that explore the characteristics of POE, OE, and Markov perfect equilibrium (MPE), and find that POE generally performs well in highly concentrated markets. We also derive error bounds for evaluating the performance of POE for cases where MPE cannot be computed. 相似文献

This article provides evidence on the role of subcontracting in the auction‐based procurement setting with private cost variability and capacity constraints. We demonstrate that subcontracting allows bidders to modify their costs realizations in a given auction as well as to control their future costs by reducing backlog accumulation. Restricting access to subcontracting raises procurement costs for an individual project by 12% and reduces the number of projects completed in equilibrium by 20%. The article explains methodological and market design implications of subcontracting availability. 相似文献

正我人生中第一次听说"重庆"这个名字,是在我离开波兰的前几天。我是来自波兰的广告从业者Przemek,中文名"浩宇"。在广告业方面,我已经有10年的工作经验,特别是在地方品牌方面颇有研究,这里就来"研究"一下重庆。像大多数外国人一样,我原来只听说过北京、上海。对于重庆,我却是连名字都未曾听说过。尽管如此,我已经在重庆居住5年了,我把自己称作"重庆 相似文献

This article estimates fixed‐cost efficiencies from mergers using a dynamic oligopoly model in which mergers and repositioning of products are endogenous. The inference is based on revealed preference approach selecting cost synergies that rationalize observed merger decisions. The estimates can be used to assess the total welfare impact of retrospective and counterfactual mergers. The framework is applied to estimate cost efficiencies after the 1996 deregulation of U.S. radio industry. Within the period of 1996 to 2006 the cost savings resulting from mergers amount to $1.2 billion per year (equally split across economies of scale and within‐format cost synergies). 相似文献

This article analyses the impact of exchange rate regimes on the real sector. While most studies in this field have so far concentrated on aggregate variables, we pursue a sectoral approach distinguishing between the tradable and non-tradable sectors. First, we present a survey of the relevant theoretical and empirical literature. This demonstrates that evaluations of exchange rate regimes and their impact on the real economy are largely dependent on specific assumptions concerning, in particular, the parameters of a utility function, the nature of the price adjustment process and the characteristics of the shocks analysed. Second, we conduct an empirical analysis of the behaviour of the tradable and non-tradable sectors under different exchange rate regimes in seven Central and Eastern European countries. We find no firm evidence of a differential impact of given exchange rate regimes on the dynamics of output and prices in the two sectors. We proffer a conceptual and technical interpretation of this. 相似文献
