“…Table 1 shows the descriptive statistics of the indices in the 2001-2016 period. For the HHI, Resende (1994) proposes the following classification criterion: ∈] 0,0.01] indicates a highly competitive market, but if ∈] 0.01,0.15], we have an indication that it is not concentrated, with a good level of competition. In the interval ∈] 0.15,0.25] there is concentration, but it is moderate.…”

This paper studies two aspects of the automobile insurance market in Brazil: first, it determines the degree of competition among insurance companies, and second, it estimates and analyzes the demand for automobile insurance. Most of the studies on the automobile insurance market in Brazil analyze the performance of the firms in this sector or present regional studies of the demand for insurance and its determinants. Thus, this study innovates both in showing the competition among the firms and estimating the demand for insurance in the country. The relevance of this research lies in the sequential and ordered way it analyzes the demand in a sector. Firstly, it identifies the type of competition that takes place in the sector and then, based on this, it proposes a structural framework based on optimizing decisions for estimating the price, income, and market power elasticities of demand. Furthermore, analyzing the insurance industry is of the utmost importance since it moves significant amounts of financial resources and provides an essential service in the economy. With information about the market structure and demand profile in the automobile insurance sector it is possible to propose strategic policies for individual firms as well as for the whole sector in order to introduce more efficiency. To analyze the degree of competitiveness, several concentration indices were calculated using annually-aggregated monthly data on the premium paid to all the automobile insurance firms in the period from 2001 to 2016. To estimate the demand for automobile insurance, half-yearly data from 2002 to 2010 for each one of the 27 federative units of Brazil were used. Two main findings are presented in this study. First, we find evidence of little concentration in the Brazilian automobile insurance market, with shares being well distributed among the players. Second, we estimate the demand for automobile insurance in Brazil and find a price-elasticity of -0.47 in the short run and -1.33 in the long run, while the lagged profitability has a negative impact on the amount insured: -0.21 in the short run and -0.59 in the long run. Income does not significantly influence the demand for insurance in Brazil.

Regional Concentration of Charcoal Production in the State of Paraíba, Brazil (1994 - 2016)

Charcoal has an economic, social and environmental importance, because in addition to being a source of energy, it generates employment and income in the rural environment. Therefore, knowing your market is fundamental for the decision-making of those segments that depend on this raw material. This work analyzed the regional concentration of charcoal production in the state of Paraíba, Brazil, from 1994 to 2016. The data used to measure the regional production concentration (in tons) of native Paraíba charcoal were obtained from the Brazilian Institute of Geography and Statistics (IBGE) from 1994 to 2016. The indicators used were the Concentration Ratio [CR(k)], the Herfindahl-Hirschman Index (HHI), Theil's entropy index (E) and the Gini Index (G). The main results show that the mesorregions of Borborema and Sertão Paraibano present concentrations in charcoal production from Paraíba. The CR(k) of the municipalities had a low to moderately low concentration and a moderately high to a high concentration for the microregions; the HHI and E showed deconcentration tendencies from competitive markets; the G showed strong to very strong inequality for the municipalities and microregions on average. It is concluded that the concentration of charcoal production at regional levels is not concentrated, even though it presents a moderate concentration in the partial indices [CR(k)] for the Paraíba microregions.

“…Para fazer uma análise comparativa, em um setor em que ocorre a variação no número de companhias, Resende (1994) sugere um ajuste no índice HHI, fazendo que o intervalo desse índice passe a variar entre 0 e 1, assim, o mais distante de zero denota um mais alto grau de concentração.…”

ResumoApós a implementação do Plano Real em 1994, o setor bancário brasileiro passou por uma profunda mudança dada a necessidade de adequação ao contexto de baixa inflação, resultando em perda das receitas provenientes do float bancário. As principais mudanças ocorridas foram um amplo processo de consolidação bancária, com fusões e aquisições, diminuição significativa de bancos com controle estatal e a facilitação para a entrada de instituições estrangeiras no mercado financeiro nacional. A fim de elucidar tais fatos utilizaram-se índices de concentração e uma análise empírica de dados, em que se constatou que houve uma mudança estrutural na indústria financeira, sendo que, o setor público perde grande parte da sua participação relativa, em contrapartida, o setor privado aumentava sua participação, principalmente, com a entrada de bancos estrangeiros no sistema financeiro nacional. Palavras-Chave: Concentração Bancária, Índices de concentração, Setor Bancário brasileiroClassificação JEL: G15, G30, G34 INTRODUÇÃOCom o sucesso da estabilidade de preços que adveio com o Plano Real, o setor bancário teve que se adequar a uma nova conjuntura econômica Textos de Economia, Florianópolis, v.13, n.2, p.59-86, jul./dez.2010 4 De Paula (1998, p.9) destaca que as receitas obtidas com floating consistiam basicamente na manutenção no passivo dos bancos de saldos não-remunerados que, aplicados, rendiam, pelo menos, algo próximo da correção monetária.
