In this paper we study a behavioral model of conflict that provides a basis for choosing certain indices of dispersion as indicators for conflict. We show that the (equilibrium) level of conflict can be expressed as an (approximate) linear function of the Gini coefficient, the Herfindahl-Hirschman fractionalization index, and a specific measure of polarization due to Esteban and Ray. JEL-Classi...

Market power refers to conditions where the providers of a service can consistently charge prices above those that would be established by a competitive market. There are many well known definitions of market power, including indices intended to quantify the degree of market concentration of energy supplies. Unfortunately, market power considerations within electric power markets require the co...

INTRODUCTION Hospitals are studying the focused factory concept and attempting to increase their power in a competitive industry by becoming more specialized. METHODOLOGY This study uses the information theory index (ITI) and the Herfindahl-Hirschman index (HHI) to analyze the extent of specialization by Korean hospitals that receive national health insurance reimbursements. Hierarchical regr...

I investigate whether the removal of the reserve clause in professional baseball a ected the competitive nature of the industry in the context of whether teams are actively attempting to monopolize in highvalued inputs. It is possible that a very few teams could purchase all of the best players over time leading to a highly concentrated industry in certain production categories and adversely a ...

The paper analyses how customers of public health organizations can express their dissatisfaction for the services offered to them. The main aim is to evaluate the effects that possible dissatisfaction of Italian public health service customers can have on public health organizations. We adopted the methodological scheme developed by Hirschman with exit, voice, and loyalty, considering the macr...

We study gatekeeping physicians' referrals of patients to specialty care. We derive theoretical results when competition in the physician market intensifies. First, due to competitive pressure, physicians refer patients to specialty care more often. Second, physicians earn more by treating patients themselves, so refer patients to specialty care less often. We assess empirically the overall eff...

This paper investigates the pricing of patented traits in the U.S. hybrid corn seed market under imperfect competition. In a multiproduct context, we first examine how substitution/complementarity relationships among products can affect pricing. This is used to motivate multi-product generalizations of the Herfindahl-Hirschman index (GHHI) capturing cross-market effects of imperfect competition...

Existing studies of the trade-conflict relationship focus primarily on dyadic trade and its implications for the opportunity cost of conflict. Most states maintain economic relations with numerous partners, yet few studies have examined the effects of extradyadic trade on dyadic conflict. In an influential discussion of economic interdependence, Albert Hirschman ([1945] 1980) draws attention to...

We study the effect of hospital market concentration on the quality of patient data protection practices. We use approximately 200 reported data breaches in US hospitals over the period 2006 2011 as a measure of the quality of patient data protection practices. We measure market concentration using the Herfindahl-Hirschman Index (HHI) and estimate our models by exploiting cross-sectional HHI va...

Recently, reading comprehension tests for students and adult language learners have received increased attention within the NLP community as a means to develop and evaluate robust question answering (NLQA) methods. We present our ongoing work on automatically creating richly annotated corpus resources for NLQA and on comparing automatic methods for answering questions against this data set. Sta...
