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 a suitable monotone transform of the equilibrium level of conflict can be proxied by a linear function of the Gini coefficient, the Herfindahl-Hirschman fractionalization index, and a specific measure of polarization due to Esteban and R...

BACKGROUND In 2006, the Dutch hospital market was reformed to create a more efficient delivery system through managed competition. To allow competition on quality, patient experiences were measured using the Consumer Quality index (CQI). We study whether public reporting and competition had an effect on the CQI between 2006 and 2009. METHODS We analyzed 8,311 respondents covering 31 hospitals...

While the globalization process makes world a big market without borders, it offers important opportunities to economies. On other hand, increases risk of fragility for economies that cannot manage properly. If export mix is dependent on small number products and markets, balance economy may deteriorate when there problem specific these or markets. In this direction, aimed reduce economic polit...

The available research literature on stock performance has primarily stressed the importance of asset price theories, macroeconomic and microeconomic, institutional differences. However, there is still an open question: Are any other factors those influence performance? This aims to answer this question by providing new insights into industry along with country-level firm-specific in conjunctio...

In studies on the nutritional requirements of Bacillus subtilis during mycobacillin formation in complex media, it was observed that the addition of a mixture of salts (KH2PO4, MgSO4, FeSO4, and MInSO4) to a casein hydrolyzateglucose medium greatly enhanced mycobacillin formation (AIajumdar and Bose, 1959). Reports by a number of workers (Jansen and Hirschman, 1944; Hendlin, 1949) indicate that...

Economists have long used state-collected discharge data to construct Hirschman-Herfindahl (HH) indices measuring hospital competition. Since data are collected to determine the facility providing the service rather than ownership, the difference between the number of reporting facilities and the number of competitors has grown over time due to mergers and networking activities. Consequently, t...

The first paper, by Seneff, Hirschman and Zue, concerned the ATIS domain. The authors state what seems, after it is pointed out, an obvious truth, but which too few system builders seem to understand: when attempting a project like ATIS, the time to worry about the kinds of interaction that will take place in a dialogue is at the very beginning of the project. The MIT ATIS system has not yet be...

ABSTRACT Faced with the transition in global energy structure shift consumption of fossil fuels to renewable and clean sources, there has been an increase demand for forest biomass purposes, especially wood pellets, imports have grown recent years. Therefore, this study analyzed world concentration pellet from 2012 2018. Data on were obtained Food Agriculture Organization United Nations (FAO), ...

This thesis examines the e ect of horizontal market structure among beef cattle producers on pass-through of international beef prices to local saleyard cattle prices. The measure of market concentration used is the Her ndahl-Hirschman Index ( HHI ). HHIs are constructed using newly-available disaggregated cattle herd size data for 9 regions across the state of New South Wales. A time-invariant...
