Different approaches to measure the hospital competition index might lead to inconsistent results of the effects of hospital competition on innovation adoption. The purpose of this study is to adopt a different approach to define market area and measure the level of competition to examine whether hospital competition has a positive effect on hospital behavior, taking quality indicator projects ...

The aim of the research is to determine impact COVID-19 pandemic (and subsequent state aid) on selected financial indicators tour operators operating Slovakia’s market. article analyses changes in market between 2018 and 2020 (market concentration, insolvency insurance). For purposes describing position operators, medians were processed. At same time, a two-sample t-test was used test hypothese...

Abstract This paper derives a European Herfindahl–Hirschman concentration index from 15 micro-aggregated country datasets. In the last decade, rose due to reallocation of economic activity toward large and concentrated industries. Over same period, productivity gains an increasing allocative efficiency market accounted for 50% growth while markups stayed constant. Using country-industry variati...

Purpose The relationship between real exchange rate and services export diversification is at the heart of this study. Design/methodology/approach analysis performed using a sample 113 countries over period 1985–2014, 2-step system Generalized Method Moments (GMM) approach. uses both Theil index Herfindahl–Hirschman concentration. Findings shows that full sample, effective appreciation induces ...

We examine the relationship between multi-blockholder contestability and coalition firm risk using an unbalanced panel of 646 Korean non-financial firms with 7,582 firm-years from 2010 to 2017 (8 years). For contestability, we use second-to-first blockholder index second-and third-to-first index. The Herfindahl-Harshman Index Concentration Difference are used for a coalition. Using different me...

Abstract The relative importance of key state-level outcomes upon U.S. national corn and soybean production was examined using correlated component regression , a recently developed technique for application to multicollinear sparse data sets. Standardized coefficients were used rank the states’ importance. A Herfindahl-Hirschman Index measure degree concentration among top ranked states. empir...

The paper examines the structure and nature of cropping pattern, crop diversification, crop concentration, productivity level and inter-districts disparity in the state of Odisha based on the secondary data collected for the period 1980 – 2005 from different published sources. The study has used Herfindahl index, location quotient, Gini coefficient and panel data regression for analysis. The st...

This study investigates how energy structure and energy security in China will change in the future under climate mitigation policy scenarios using Representative Concentration Pathways in a computable general equilibrium model. The findings suggest that to reduce greenhouse gas emissions, China needs to shift its energy structure from fossil fuel dominance to renewables and nuclear. The lower ...

Using a maximum entropy technique, we estimate the market shares of each firm in an industry using the available government summary statistics such as the four-firm concentration ratio (C4) and the Herfindahl-Hirschmann Index (HHI). We show that our technique is very effective in estimating the distribution of market shares in 20 industries. Our results provide support for the recent practice o...

In recent years, ethnic fractionalization has emerged as a central variable in quantitative analyses of outcomes ranging from economic growth rates (Easterly and Levine, 1997) and the quality of governance (La Porta et al, 1999) to ethnic conflict (Kay et al, 2000) and the frequency of coups d’etat (Londregan and Poole, 1990). Almost all such analyses employ, either alone or in combination with...
