Full textAbstract:
The purpose of this study was to measure the competition level of general hospitals in Poland. The Herfindahl-Hirschman Index (HHI) was used to investigate the concentration level of the general hospital sector in Poland, which is treated in the literature as a proxy of competition. To understand how general hospitals’ market has been structured and thus competitive, the data for general hospitals spanning all Poland for the period of 2005-2013 were collected. The concentration of hospitals was measured in each of the 16 provinces in Poland based on the aggregated data at the counties level. Data are collected from the public statistical system. The HHI indices support the assertion that in the period of analysis the entire general hospitals’ sector in Poland has been on average moderately concentrated and thus, moderately competitive with the growing tendency to higher concentration and less competition. Moreover, the concentration of hospitals’ services is diversified across the provinces and regions of Poland and it is quite uneven. The analysis also shows that changes in the health care market, which took place in the analysed period, especially statutory changes regarding hospitals in 2011, affected the level of concentration and thus competition. Including this introduction, this paper is organized into six sections. Section 2 outlines the Polish health care reforms especially those applying to hospitals. Section 3 and 4 presents the concept of empirical research, such as data and method. Section 5 provides results of empirical research and section 6 concludes.

The paper analyses the phenomenon of market concentration in the context of the most popular industrial organization approaches: the structure- conduct-performance (SCP) approach and the efficiency hypothesis (EH). The theory of market concentration evaluation is briefly presented, followed by an analysis of the main concentration indicators and their application in recent empirical research. The main problem in the practical application of the Herfindahl-Hirschman index (HHI) - the necessity to incorporate the market shares of all the enterprises in the market - is further addressed and the issue of calculating the minimum value of the HHI is analysed from the theoretical point of view and by modelling hypothetical markets.

This work analyzed the Brazilian cellulose industry concentration level between 1998 and 2007, focusing on the sector's main performance indicators. The necessary data was collected from BRACELPA's Statistical Reports during the same period. The concentration level was determined according to the following indexes: Concentration Ratio (CR); Herfindahl-Hirschman Index (HHI); Theil's Entropy Index (E); and the Gini Coefficient (G). The primary conclusions were that the CR(4), CR(8), HHI, and Theil's indexes presented high figures in spite of occasional fluctuations. The inequality of the industry, as measured by the Gini coefficient, was considered high, confirming the initial hypothesis of the work.

Full textAbstract:
Understanding the impact of heterogeneity on the evolution of group opinions can enlighten us on how to effectively organize, redesign, and improve decision-making efficiency. This article explores mainly the effects of heterogeneity on the evolution of group opinions. It is found that the heterogeneity of individuals’ openness has an important influence on the ability to aggregate group opinions. According to the average amount of clusters and Herfindahl–Hirschman Index (HHI) under different network structures, heterogeneity often improves the ability. In addition, for the small-world network and random network, there is little difference in the aggregation ability from both the average amount of clusters and the Herfindahl–Hirschman Index. While for the regular network, the ability is obviously weaker than that of the other two. This result also shows that the randomness of interaction between members will enhance the cohesion of a group.

Urgency of the research. The impact of competition on the cost of banking services, availability of financial resources, efficiency and speed of transformation of savings into investments determines the relevance and timeliness of developing an appropriate methodological approach, which involves calculating Herfindahl-Hirschman index (HHI) to determine the competitive structure of the Ukrainian banking market. Target setting. Assessing the level of competition is the basis for establishing the relationship between the financial performance of banking and the competitiveness level of the bank and determine its ability to respond quickly to changes in market conditions. Actual scientific researches and issues analysis shows the importance of in-depth diagnosis of the level of banking competition to address the strategic development of banks. Uninvestigated parts of general matters defining. The issues of assessing the level of competition in key segments of the banking market remain insufficiently researched. The research objective. A study of modern aspects of competition in the banking market and improvement of the methodological approach to assessing the competitiveness of banks using the Herfindahl-Hirschman Index (ННІ) The statement of basic materials. The proposed methodological approach involves the consistent implementation of the following procedures: assessing the level of penetration of the banking sector into the economy; determining the conditions of a competitive market; assessment of the concentration level using the Herfindahl-Hirschman Index. Conclusions. Approbation of this approach allowed to confirm the thesis of increasing the level of oligopolization of the industry. The results of the calculation of the Herfindahl-Hirschman Index, which takes into account the situation in the industry as a whole, and not only among market leaders, allows us to draw conclusions about the growing oligopolization of the banking market.

The pharmaceutical industry of Pakistan is now meeting around 80% of total domestic demand with an annual11% growth rate. But the question arises as to whether the firms produce efficiently? The paper measures cost efficiency of the pharmaceutical industry of Punjab using Data Envelopment Analysis (DEA) for the period of 2014-15. The factors affecting the cost efficiency is also determined by using Tobit method. In first stage, value added is used as single output and number of employs, raw material, and cost of salary are as inputs. The result suggested that the cost efficiency of the pharmaceutical firms is 27.7% which is determined by 46% technical efficiency (TE) and 60.8% allocative efficiency (AE). It means wastage of resources is cost increasing factors in these firms. In the second stage, among the variables i.e. firm’s market share, firm’s Herfindahl-Hirschman Index (HHI) of market concentration, values of assets, energy, Herfindahl-Hirschman Index has strong positive effect on cost efficiency.

Full textAbstract:
This paper aims to prove that the Herfindahl-Hirschman Index (HHI), which is widely used to describe the concentration of a given market, may not be a good competitiveness indicator as many authors assume when dealing with a mobile market. This paper shows that even if the HHI formula itself is not in doubt, but when used for a market which meets two basic criteria: it is regulated and has limited resources (the frequencies used to provide mobile service are not infinite, which implies the limitation on the number of firms in the segment), its result can be misleading. In a market segment, where the two previously mentioned conditions are met, the interpretation of an HHI output value is almost known in advance. According to the current interpretation of an HHI output value, no mobile market in the world is highly competitive, which elicits some questions.

Full textAbstract:
Product differentiation is a reality in today's consumer markets and warrants further study in antitrust analysis because product differentiation increases market power. Currently the FTC and Department of Justice rely on the Herfindahl-Hirschman index (HHI) to detect market power. However, the HHI is not sensitive to product market differentiation. The author uses marketing tools of market structure analysis to propose a new measure of concentration, the market concentration index (MCI), that reflects product market differentiation. The rationale for the new measure is based on marketing theory, antitrust court opinion, and the antitrust economics literature. MCI is compared with HHI and is shown to have several practical and theoretical advantages. The 1986 proposed mergers in the carbonated soda market are analyzed by means of both measures. The empirical work demonstrates MCI's ability for detecting changes in product market differentiation.

Thesis (PhD)--Stellenbosch University, 2012.ENGLISH ABSTRACT: This dissertation examines the measurement of business concentration by the Herfindahl- Hirschman Index (HHI). In the course of the examination, a modification to this method of measurement of business concentration is proposed, in terms of which the accuracy of the conventional depiction of the HHI can be enhanced by a formulation involving the Gini index. Computational advantages in the use of this new method are identified, which reveal the Ginibased HHI to be an effective substitute for its regular counterpart. It is found that theoretically and in practice, the proposed new method has strengths that favour its usage. The practical advantages of employing this method are considered with a view to encouraging the measurement of business concentration using the Gini-based index of the HHI.
AFRIKAANSE OPSOMMING: Hierdie verhandeling ondersoek die meting van sakekonsentrasie deur middel van die Herfindahl- Hirschman-indeks (HHI). ‘n Wysiging aan hierdie metode word voorgestel, deur middel waarvan die akkuraatheid van die konvensionele voorstelling van die HHI verhoog word, deur ‘n formulering wat die Gini-indeks betrek. Die berekeningsvoordele van hierdie nuwe metode word geïdentifiseer en dit word aangetoon dat die Gini-gebaseerde HHI ’n doeltreffende plaasvervanger vir sy meer bekende teenvoeter is. Daar word bevind dat die voorgestelde nuwe metode teoretiese en praktiese sterkpunte het wat die gebruik daarvan ondersteun. Die praktiese voordele van die voorgestelde metode word oorweeg met die oog op die aanmoediging van die gebruik van die Gini-gebaseerde HHI-indeks as maatstaf van sakekonsentrasie.

Mestrado em FinançasCom este estudo pretende-se saber como tem evoluído a concentração e a eficiência nos últimos anos (2004-2010) no sector bancário de Cabo Verde. Para o efeito, recorreu-se ao Herfindahl-Hirschman Index (HHI) para estimar a concentração e à metodologia Data Envelopment Analysis (DEA) para estimar à evolução na eficiência técnica, eficiência técnica pura e eficiência de escala. Como complemento efectuamos uma análise de alguns dos principais rácios financeiros a nível de produtividade, eficiência e rendibilidade de forma a fazer uma pequena comparação com os outputs da metodologia DEA. Os dados foram obtidos e calculados a partir dos relatórios e contas consolidadas referentes aos bancos no período em análise. Os resultados obtidos com o HHI permitiram identificar, que o mercado é ainda bastante concentrado, apesar de existirem claras evidências da diminuição do grau de concentração ao longo do período analisado. Da mesma forma no que respeita à evolução na eficiência, os resultados encontrados com a metodologia DEA apontam para uma evolução positiva relativamente á eficiência, em linha com as tendências observadas nas variáveis de produtividade e rendibilidade. Em conclusão, o sector bancário de Cabo Verde está num bom caminho para se tornar num sector cada vez mais eficiente, desenvolvido e competitivo.
This work aims at studying the evolution of both concentration and technical efficiency of Cape Verde banking sector over the period 2004 through 2010. The Herfindahl-Hirschman Index (HHI) was used to estimate the concentration whereas data envelopment analysis (DEA) was employed to estimate technical efficiency evolution. In addition, we performed an analysis of the banking sector key financial ratios and compared them with the DEA results. Data were gathered from bank reports. HHI results show the market is highly concentrated despite the fact that the concentration level shows a decreasing trend over the period under analysis. As far as the technical efficiency is concerned, DEA results show a positive evolution. This finding is in line with the observed trends for productivity and profitability ratios. Results suggest the Cape Verde banking sector is set to become more efficient, developed and competitive.

Studien går ut på att analysera marknadsstrukturen för två industriföretag(Holmen och SCA) under antagandet att båda konkurrerar mot varandragenom att köpa rå material samt genom att sälja förädlade produkter.Produktmarknaden som undersöks är pappersmarknaden och antas varakoncentrerad. Rå materialmknaden som undersöks ärmassavedmarknaden och antas karaktäriseras som en duopsony. Detvisade sig att Holmen och SCA köper massaved från en stor mängdskogsägare. Varje företag skapar varje månad en prislista där de bestämmerbud priset föassaved. Priset varierar beroende på region. Både SCA ochHolmen väljer mellan två strategiska beslut, antigen att buda högt pris ellerlågt pris. Genom spelteori så visade det sig att båda industriföretagenanvänder mixade strategier då de i vissa tillfällen budar högt och i andratillfällen budar lågt. Nash jämviktslägen för mixade strategier räknades utmatematiskt och analyserades genom dynamisk spelteori.Marknadskoncentrationen för pappersmarknaden undersöktes viaHerfindahl-Hirschman index (HHI). Porters femkraftsmodell användes föratt analysera industri konkurrensen. Resultatet visade attproduktmarknaden är koncentrerad då HHI testerna gav höga indexvärdenmellan 3100 och 1700. Det existerade dessutom ett Nash jämviktsläge fö mixade strategier som gav SCA förväntad lönsamhet 1651 miljoner kronoroch Holmen 1295 miljoner kronor. Dynamisk spelteori visade att SCA ochHolmens budgivning följer ett mönster och att högt/lågt bud beror påavvikelser från Nash jämviktslägets sannolikhetsdistribution. Nashjämviktslägets råder ifall sannolikhetsdistributionerna vid låg budgivningär 68,6 procent för SCA och 66,7 procent för Holmen. Detta gav indikatore för icke samarbetsvilliga spel. Slutsatsen är att om två spelare (kvarnar) nårThe research aims to analyze the market structure of two companies in th forest industry (Holmen and SCA) with the assumption that thes companies compete at buying raw materials and selling products. Theproduct market in this study is the paper market under the assumption thatboth companies operate in a concentrated product market. The rawmatial market that one investigates in this study is the pulpwood marketunder the assumption that it is a duopsony. What this study has concludedis that Holmen and SCA buy pulpwood from lots of different self-managingforest owners. Each company creates a monthly pricelist where they decidethe bid price of pulpwood. The amount varies depending on the region. Bot SCA and Holmen chooses between two strategic decisions, either to bid highor to bid low. Through game theory, it has been clear that each company usesmixed strategies as they sometimes give high bids and sometimes give lowbids. The Nash equilibrium for mixed strategies have been calculatedmathematically and analyzed through the dynamics of game theory. As fore market concentration, the product market has been investigatedthrough the Herfindahl-Hirschman index (HHI). Porter's five-force modelwas used to analyze the industry competition. The results showed that theproduct market is concentrated as the HHI tests gave High index scoresbetween 3100 and 1700. In addition, there existed a Nash equilibrium in amixed strategy that gave SCA expected payoff 1651 million SEK and Holmen1295 million SEK. The dynamic game theory showed that SCA and Holmen'sbidding follows a repeating trajectory and that the high/low bidding is dueto deviations from Nash equilibrium probability distribution. The Nashequilibrium situation prevails if the probability distribution at low biddingis 68.6 percent for SCA and 66,7 percent for Holmen. This providedindicators for a non-cooperative game. The conclusion is that if two players

This study applies patent analysis to explore the performance of the American pharmaceutical industry by means of artificial neural network (ANN). The research objects were 39 American pharmaceutical companies and the research period was 2000-2014. The data of this study were collected from the United States Patent and Trademark Office (USPTO) database, the COMPUSTAT database and the Westlaw database. Besides, this paper explores the influences of R&D expenditures, RTA, HHI of patents and patent litigation on corporate performance. The result indicates that the R&D expenditures have positive effect before reaching the optimal point and have negative effect after reaching the optimal point. The higher RTA indicates that the company has stronger technical advantage in specific technology fields, which resulted in the better performance. Otherwise, the HHI index of patents has negative influence on corporate performance. Therefore, if the pharmaceutical companies want to enhance their performance, they should focus on diversification of technology. Finally, the number of patent litigations has positive influence on corporate performance.

Full textAbstract:
This thesis presents an econometric methodology for analyzing the impact of market concentration (HHI) on the day rate prices paid by E&P operators for the lease of drilling rigs. It is an extension of the work of Lee (2008), ‘Measuring the Impact of Concentration in the Drilling Rig Market’. Specifically, the work entailed using a more detailed time series data than was initially used (quarterly), analyzing impact of concentration on day rate prices by water depth specification of drilling rigs, and accounting for the impact of autocorrelation on the analysis. The results for jack-ups, without adjustment for autocorrelation, supported the results of the prior study i.e. showing that increase in HHI causes rig day rate price increase. However, the results for semi-submersibles was inconclusive as it varied from region to region and also was contrary to the assumptions of positive relationships between HHI and day rate prices made in this study. These results imply that market concentration caused both price increase and decrease within the industry depending on whether it increased market power or increased cost efficiency and technological ability.text

With the globalization, the world has been becoming a much smaller place. New types of business have been emerging. Depending on this situation, new corporations are founded in current and emerging sectors. This causes an increase in competition. On the other hand, a variety of sectors are regulated intensively which result in a high concentration. Banking sectors is one of these sectors at where regulations are much and entry barriers are high. It is aimed at examining concentration from competition perspectives Turkish Banking Sector (TBS). It is concluded that TBS generally has a non-concentrated industry structure in terms of total assets, total credits, total deposits, total equities, and total net profits. Exceptions are seen in total net profits and in total deposits. Concentration level generally has decreased from 1999 (1,172 on average) to 2018 (899 on average calculated by Herfindahl-Hirschman Index (HHI). It is recommended that necessary precautions should be taken by regulatory bodies in order to decrease concentration and increase competition in TBS.
