Hospitals’ strategic behaviours and patient mobility: Evidence from Italy

This study explores the behaviour of hospitals in Lombardy in attracting patients from outside the region and investigates the effects on the quality of care to regional patients, where treatment of the latter is constrained by a budget cap while extra-regional patients represent an unconstrained source of revenue. The data suggest that hospitals use waiting time and length of stay to attract extra-regional patients. Regional patients in both private and public hospitals with higher proportions of extra-regional patients are characterized by lower mortality rates and reimbursement costs. These results suggest that the market for extra-regional patients has no negative effects on resident patients. Finally, the pattern of reimbursement for extra-regional care generates a financial flow in favour of wealthier regions, exacerbating the North–South divide in the National Health Service. Some form of regulation for extra-regional mobility is advisable to reduce the gap.

China??s banking system, market structure, and competitive conditions

This paper presents an empirical assessment of the market structure and the competitive conditions of the Chinese banking sector. We applied the Panzar-Rosse H-statistic on the data collected from a panel including 16 most significant Chinese banks for the period 2004–2007. Equilibrium tests and the competitive conditions tests were applied on the data. From the pooled regression in the whole period, we found that the banking sector in China for 2004–2007 was monopolistically competitive. We also show that the Chinese banks were not able to achieve high records of profitability in monopolistically competitive markets.     

基于产品差别理论的电视节目类型趋同研究

本文建立了一个空间竞争模型分析电视节目类型趋同现象。节目类型的趋同意味着频道间节目的水平差别变小,而电视节目差别的的实质是产品差别。如果将观众的效用函数设定为节目类型距离的线性函数,电视频道间节目的水平差别必然实现最小化,节目类型完全相同。

Comment on ‘Competition Tests with a Non‐Structural Model: The Panzar–Rosse Method Applied to Germany's Savings Banks’

Abstract. In a recent issue of this journal Gischer and Stiele (2009) applied the ‘Test for “Monopoly” Equilibrium’ advanced by Panzar and Rosse (1987) to German savings banks and came up with the claim that savings banks maximize profits under conditions of monopolistic competition in the meaning of Edward Chamberlin. Their proposition is not conclusive since it would require free entry and for savings banks to operate under increasing returns to scale. Available evidence, however, shows them being subject to constant or decreasing returns to scale. The empirical findings of Gischer and Stiele can more convincingly be explained by assuming savings banks abide by their legal goals to pursue the public interest.     

Information aggregation in auctions with an unknown number of bidders

Information aggregation, a key concern for uniform-price, common-value auctions with many bidders, has been characterized in models where bidders know exactly how many rivals they face. A model allowing for uncertainty over the number of bidders is essential for capturing a critical condition for information to aggregate: as the numbers of winning and losing bidders grow large, information aggregates if and only if uncertainty about the fraction of winning bidders vanishes. It may be possible for the seller to impart this information by precommitting to a specified fraction of winning bidders, via a proportional selling policy. Intuitively, this could make the proportion of winners known, and thus provide all the information that bidders need to make winner's curse corrections.     

双重垄断下中国垄断行业改革:逻辑次序与路径选择

我国的垄断现状是由传统的计划经济体制衍生而来的,其本质特征是寄附于自然垄断之上的过度行政性垄断。垄断行业改革涉及竞争、产权、规制与治理等多个层面,它们之间的不同组合及其协同互动关系共同决定了特定行业的产业绩效水平。中国的垄断行业改革,必须遵循优先重构规制体系、分类渐次破除行政性垄断的总思路,从产权、竞争、规制与治理等各个层面作出相应的制度安排。     

机遇管理与企业竞争优势

本文从企业成长过程中所面临的问题出发,运用机遇管理理论分析了企业辨识、评价、利用和营造机遇的运行机制,阐释了企业发展过程中机遇管理的重要性和必然性。从经济学的视角来看,企业的竞争优势来源于经济租金,经济租金可以分为基于低成本和差异化的张伯伦租金、基于资源和能力的李嘉图租金、基于知识和创新的熊彼特租金。本文分析了企业机遇管理在企业获取经济租金、建立竞争优势中的作用,分析了机遇管理与低成本和差异化、资源和能力、知识和创新之间的关系。本文认为,机遇管理有利于获得与维持企业租金：企业通过机遇管理有助于实现低成本和差异化,获取张伯伦租金;有助于企业获得稀缺资源,提高能力,获取李嘉图租金;有助于企业积累知识,促进创新,获取熊彼特租金。本文从经济学的角度分析了企业竞争优势的来源,论证了企业租金的来源正是企业竞争优势的来源,探索了企业通过机遇管理建立竞争优势的新方法、新途径。
