Abstract:
This paper explores the relationship between bank competition and financial sector stability using 20052010 data for ten African countries. The study utilises a Generalized Method of Moments approach to regress bank stability indices Z-score, non-performing loans ratio and return on banks assets on bank competition indices Lerner-Index, Herfindahl-Hirschman Index total assets and Herfindahl-Hirschman Index total deposits. The findings show a robust positive relationship between market power and financial stability. This unequivocally suggests that there is a trade-off between bank competition and financial sector stability in these countries, as per the competition-fragility view.

Abstract:
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.

Abstract:
The study examined the structure and marketing efficiency of cassava in Ado-Ekiti Local Government Area of Ekiti State, Nigeria. Primary data were obtained using structured questionnaires and multistage sampling method was employed to select 183 respondents comprising 93 farmers and 90 marketers. The Herfindahl-Hirschman Index and Gini Coefficient were used to measure the degree of market concentration and the nature of competition in the market. The Herfindahl-Hirschman indices were 0.323, 0.346, and 0.316 for farmers, wholesalers, and retailers, respectively, suggesting that the market was uncompetitive at all levels. The computed values of Gini coefficient for cassava farmers, wholesalers, and retailers were 0.532, 0.465, and 0.569, respectively, indicating uneven distribution of income and uncompetitive market conditions. Two channels of cassava marketing were identified and the study demonstrates that the farmer-wholesaler-retailer-consumer channel had higher marketing efficiency and thus provides marketers with better opportunities for making more profits. Based on the findings, it is recommended that micro credit facilities should be made accessible to market actors to encourage investment and improve efficiency in cassava marketing.

Thesis (PhD)--Stellenbosch University, 2012.<br>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.<br>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.

Abstract:
After the financial crisis, several comparison websites have emerged for private lenders to enable comparison on mortgage terms. The idea behind the comparison pages is that they should be used by the private borrower. On June 1, 2015, a new directive emerged from the Swedish Financial Supervisory Authority to the credit institutes that instead of the list interest, the average interest rate that the lenders offer their customers should be the one published, in order to further increase the transparency of the price. The purpose of this study is to investigate whether competition in the mortgage market has improved after the introduction of the comparison websites and the effects of the increased price transparency. In order to investigate the competition on the mortgage market, the theory of market forms and the Herfindahl-Hirschman Index has been applied. The result of the study shows that the concentration of competition has increased over time. This study also shows that the comparison pages have contributed to increased price transparency that has contributed to consumers information about the market. This study is limited to the Swedish mortgage market.<br>Efter finanskrisen har flertalet jämförelsesidor uppkommit för att möjliggöra jämförelser av räntor och villkor på bolån. Jämförelsesidor ska förenkla processen att jämföra de olika långivarna. Den 1 juni 2015 kom ett nytt direktiv från finansinspektionen till långivarna att istället för listräntan ska den genomsnittliga räntan som långivarna ger sina kunder vara den som publiceras, för att öka pristransparensen ytterligare. Denna studies syfte är att undersöka hur konkurrensen på bolånemarknaden har förändrats efter jämförelsesidornas tillkomst med HHI-index och konkurrensteori. Teori om marknadsformer och Herfindahl-Hirschman Index att tillämpas för att undersöka konkurrensen. Resultatet av studien visar att koncentrationen av konkurrensen har ökat över tid. Denna studie visar även att jämförelsesidorna har bidragit med ökad pristransparens som har bidragit till konsumenternas information om marknaden. Studien är avgränsad till den svenska bolånemarknaden.

Abstract:
Mestrado em Finanças<br>Com 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.<br>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.

Abstract:
Den 1 juli 2010 implementerades PSI-lagen i Sverige, syftet var att främja konkurrens och tillväxt i informationsförädlarbranschen. En bransch som beräknas ha en stor tillväxtpotential. Branschen saknar idag en egen klassifikation, vilket medför att branschens utveckling är svår att mäta. Denna studie avser att dels skapa en definition för informationsförädlarbranschen, och ta reda på vilka företagen i branschen är. Sedan kommer konkurrens och tillväxt i informationsförädlarbranschen att mätas för att undersöka om PSI-lagen haft någon inverkan på branschens utveckling. Resultatet visar att branschen består av 130 företag, år 2013, och att tillväxten och konkurrensen har förändrats sedan PSI-lagen implementerats.

Abstract:
This master thesis is focused on the market concentration in six sectors of public procurements in the Czech Republic, and the relationship between level of market concentration, profitability of the companies, final price and number of bids. The analyzed procurements refer to food industry, electricity, postal and telecommunications services, solar energy, IT and automotive sector from period of 2007-2010. Concentration ratio, Herfindahl-Hirschman index and Gini coefficient were used to quantify market concentration. The first four of above mentioned public procurement markets seem to be highly concentrated according to these indicators; the remaining two cases are unconcentrated or moderately concentrated. Correlation analysis was used for each sector. The analyzed variables were: market shares of the companies, their profitability, average number of bids and average proportion of the final and expected price in tenders which the company won. Further, the relationship between market concentration indicators and average variables for the relevant sectors was assessed.

This fact has impact in prices, which are higher in life insurance market, and indicates relevant differences between life and non life insurance markets.<br>Os mercados de seguros regulados pela SUSEP apresentaram queda no número de empresas e elevação no índice de concentração de Herfindahl Hirschman. O que parece um quadro preocupante no âmbito da regulação é atenuado pela diminuição do índice de Gini e outros testes de poder de mercado que não indicam que esta queda no número de empresas tenha tido impacto sobre o nível de preços. Assim como esperado a partir da evidência internacional, a concentração é maior nos mercados de seguros de vida do que nos não-vida. Este fato tem reflexo nos preços, que apresentam patamares mais altos nos seguros de vida, indicando diferença mais substancial entre mercados.

This thesis will examine whether the price level on the market of mobile services in comparison with other countries is high or not. After performing own international price comparison which revealed high price level in both analyzed consumer baskets thesis offers some possible options which could lead to the current high price level on the market. The observed high market concentration is one of the possible solutions and leads to discover several solutions whose analysis shows that high price level in the Czech mobile services market cannot be associated with only one factor. The price level is mainly affected by the absence of more operators which can be partly attributed to the insufficient steps of market regulator - ČTÚ especially in the area of termination fees and lease licenses to operating in mobile networks. Both of these steps are also very important for the future development of the market.

Abstract:
Syftet med studien är att analysera förändringen i de svenska partiernas politiska program genom att tillämpa Public Choice skolans modeller. Med hjälp av medianväljarteoremet och Hotellingmodellen analyseras om modellerna är tillräckligt beskrivande för Sveriges partiförflyttningar. Vidare beräknas Herfindahl-Hirschman index för graden av maktkoncentration på den politiska ”marknaden”. Herfindahl-Hirschman indexet visar att koncentrationen på den politiska marknad blivit lägre över tid, viket indikerar på att konkurrensen mellan partierna blivit allt högre under perioden 1973-2014. För att analysera om det går att förklara förändringar i partiernas politik under perioden 1973-2014 tillämpas medianväljarteoremet. En diskussion kring testning av modellen görs samt en illustration hur medianväljarteoremet skulle kunna se ut för Sveriges partier. För att analysera om en endimensionell skala är beskrivande för de svenska partiernas förflyttningar har Hotellingmodellen tillämpats. Genom att illustrera dessa två modeller på Sveriges partier undersöks om modellerna ger en tillfredställande beskrivningar av förändringen i de svenska partiernas politiska program. Analysen ger vid handen att att Medianväljarmodellen inte förklarar förändringarna i partiernas politik på ett tillräckligt utförligt sätt. Hotellingmodellen kan bättre förklar både de svenska partiernas förflyttningar på vänster-högerskalan samt förändringar i partiernas politik. Utöver de nämnda modellerna konstateras att den enskilda faktor som är mest betydelsefull för hur partierna ändrat sina politiska program är partiernas beroende av väljarnas åsikter.<br>The aim of the study is to analyze changes in the Swedish political parties programs by applying the Public Choice approach. With help from the median voter theorem and the Harold Hotelling model, the paper analyzes if these models are sufficiently descriptive of Swedens political parties movements. A Herfindahl-Hirschman index is constructed which shows changes in concentration of political power over time. The Herfindahl-Hirschman index shows that the degree of concentration in the Swedish political “market” has become lower over time, which indicates that the party competition has increased during the period 1973-2014. In order to analyze whether it is possible to explain changes in the parties’ policies during the period 1973-2014 the median voter theorem is applied. A discussion about how this model can be tested is done as well as an illustration of how the median voter theorem could look like for the parties in Sweden. To analyze whether a one-dimensional scale is descriptive of the movements of the Swedish parties, the Harold Hotelling model is also applied. By illustrating these two models on Swedens parties, the paper investigates whether these models provide a satisfactory descriptions of the change in the Swedish parties political programs. The analysis concludes that the median voter theorem does not explain the changes in the parties politics in a sufficiently detailed manner. It is revealed that the Harold Hotelling model provides a better description for both the Swedish parties movements at the left-right scale and for the changes in the parties politics. In addition to the models mentioned the factor that that is most important for how the parties changed their political programs is the parties’ dependence of the voters opinions.

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.

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).

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.

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.

Abstract:
Posner’s (1961) “technological gap theory” and Vernon’s (1966) “product life cycle theory” predicts that innovation causes market power and facilitates export. In other side export encourages firms and provides more affirmative environment for innovative processes. These theoretical approaches have different predictions regarding the direction of causality between export and innovation. Using Two-Step System Generalized Moments of Method this study investigates causality relationship between export intensity and R&amp;D intensity for the period 2008-2013 in Turkish Manufacturing Industry. Causality relationship was modeled within two different equations and analyzed by Wald Test. First equation models export intensity as function of R&amp;D intensity and real exchange rate. In the second equation R&amp;D intensity estimated as a function of export intensity and Herfindahl-Hirschman Index as competition variable. Causality test results show that there is unidirectional causal relationship from R&amp;D intensity to export intensity. This finding supports the predictions of Posner’s (1961) “technological gap theory” and Vernon’s (1966) “product life cycle theory” related to the innovation and export relationship in Turkish Manufacturing Industry.

Abstract:
The European sugar beet quota system is in very high dynamic process in recent years. The number of sugar companies involved in this system has been constantly decreasing. The aim of this paper is to define subjects (companies/alliances), which possess the current production capacities working under the production quotas system. The paper is determining especially the level of beet sugar production quota holder system concentration using the Herfindahl-Hirschman Index. The paper provides the following findings. The European quota holder system is extremely concentrated and it is becoming more and more dominated by fewer players. Sugar quota is distributed among 19 EU-Member States. In this regard, the quota is generous, especially in relation to France, Germany, Poland and United Kingdom. In Finland, Lithuania, Hungary, Sweden, Denmark, the Netherlands, Slovakia and the United Kingdom controlled by two or even one subject (companies, alliances). There is a large discrepancy between political efforts to distribute equitable R 1308/2013-sugar quotas among states and the actual reality of those distributions. While the EU-quota holder system does not indicate an extreme concentration, an analysis according to the headquarters´ location and allocated quotas to owners of production capacities provides the evidence of extreme concentration.
