Análise da estrutura do mercado brasileiro de carros populares, 1990-2005 AgEcon
Mattos, Leonardo Bornacki de; Barros, Áther de Miranda.
The objective of this paper was to analyze the evolution of the Structure of the Brazilian market of popular cars in the period from 1990 to 2005. Information on the number of units sold by each firm in the domestic market have been used to determine each firm’s market-share, levels of concentration and the Herfindahl- Hirschman Index. The results have pointed that, although reduction in the concentration of this market during the period have occurred, the market is still strongly concentrated according to the levels established by the Office of Economic Investigation (SEAE) and by the Office of Economic Defense (SDE) for the exercise of the coordinated market power.

Demanda industrial de energia elétrica em Minas Gerais, 1970-2002 AgEcon
Mattos, Leonardo Bornacki de; Reis, Bricio dos Santos; Lima, Joao Eustaquio de; Lirio, Viviani Silva.
The main objective of this paper was to obtain an estimate for the industrial electricity demand in Minas Gerais in the period from 1970 to 2002. After identifying that the series were nonstationary, it was used the Cointegration approach, being estimated a Vector Error Correction Model (VEC Model). The results showed that both price and income elasticities are inferiors to the unit. The projections for period 2004/2008 indicate that the consumption of electricity should present superior taxes of growth to the observed ones in the decade of 90.

DETERMINANTES DA ERRADICAÇÃO DA FEBRE AFTOSA NO BRASIL AgEcon
Muller, Carlos Andre da Silva; Mattos, Leonardo Bornacki de; Lima, Joao Eustaquio de.
Foot and mouth disease (FMD) has been a problem for the Brazilian livestock since the XIX century. Once it affects the livestock productivity and has always been a problem for the country exports due to the imposition of sanitary barriers. In 1992, when no state was free from FMD, the National Program for Eradication of FMD (PNEFA) was implemented. Since then good results has been obtained with control and eradication of the disease in some states. However, in other states the problem still persists. It is important to determine why some states have faced difficulties in reaching the status of free from FMD while others not. This work aimed to identify the factors which discriminate the populations of states free from FMD from those not free. The results...

Determinantes e previsão da taxa de câmbio nominal: uma aplicação do modelo de paridade da taxa de juros atrelado ao mercado monetário, 1999-2004 AgEcon
Cassuce, Francisco Carlos da Cunha; Mattos, Leonardo Bornacki de; Campos, Antonio Carvalho.
The present work looked for to show the influence of nominal variable in the determination of nominal exchange rate R$/USS. For this, the model of the parity of the tax of interests was used, ally to the monetary market. It was looked, also, to foresee the tax of exchange rate R$/USS, until December of 2005. For reaching such objectives, the equations of the system had been obtained by the Vector Error Correction Model (VECM). The results had shown that the nominal variable are very important to determinate the exchange rate and that the model of parity of the tax of interests, ally to the monetary market is confirmed for the Brazilian case in the period of analysis (jan/1999 to dez/2004). This conclusion is made on the basis of the high capacity of...

Impactos da crise financeira internacional e da influenza A sobre as exportações brasileiras de carne suína AgEcon
Ferreira, Marcelo Dias Paes; Sousa, Lucas Oliveira de; Mattos, Leonardo Bornacki de; Campos, Antonio Carvalho.
The Brazilian pork exports have been affected by several shocks on the 2000s. This paper aimed to analyze these shocks. The focus of this papers are the main international shocks on the last years: the international economics crisis and de influenza A (H1N1). Analyses were made over the main Brazilian pork exports destinations: Russia and Hong Kong. The theory of international trade was used as a theoretical framework and analysis of intervention provided methodological support. The results show that the quantum exported to Russia has not been affected by the recent shocks. However the prices was negatively affected by crisis in the short term. The quantum exported and the exports prices to Hong Kong have been negatively affected by crisis in the short...

Integração espacial de mercados na presença de custos de transação: um estudo para o mercado de boi gordo em Minas Gerais e São Paulo AgEcon
Mattos, Leonardo Bornacki de; Lima, Joao Eustaquio de; Lirio, Viviani Silva.
The analysis of market integration of agricultural commodities based on price information are limited because the effects of transaction costs are not considered in the adjustment process. The main objective of this paper was to estimate the possible transaction costs impacts on market integration of beef cattle between the states of Minas Gerais and São Paulo. It was estimated a Threshold Vector Error Correction Model (TVEC model) using monthly price data for the period from January 1972 to August 2005. The results indicated the presence of threshold cointegration implying that transaction costs have important effect on the price adjustment process.

Transmissão de preços entre mercados regionais de carne de frango no Brasil AgEcon
Mattos, Leonardo Bornacki de; Lirio, Viviani Silva; Lima, Joao Eustaquio de; Campos, Antonio Carvalho.
Non-negligible transaction costs restrict the transmission of price shock between markets. The aim of this work was to analyze the effects of transaction costs on the spatial integration of the internal market for chicken meat, from 1998 to 2007. The applied methodology was based on the Threshold Cointegration Analysis. The results indicate the presence of significant barriers to the price transmission between the markets, existing probably due to the transaction costs. Prices are not very sensitive to eventual deviations of the long run equilibrium. It could also be noted that a relatively long period is necessary to eliminate price shocks, and the price transmission process is asymmetric.

UMA ESTIMATIVA DA DEMANDA INDUSTRIAL DE ENERGIA ELÉTRICA NO BRASIL: 1974-2002 AgEcon
Mattos, Leonardo Bornacki de.
This work aims to quantify the relations between the electricity demand and its main determinants in the Industrial sector of Brazil, in the period between 1974 and 2002. After identifying that the studied series were nonstationary, the use of the Cointegration Approach and an Error-Correction Mechanism was opted . The results obtained have turned out as according to the expected. The industrial electricity demand is price inelastic in both short and long run. The results still pointed out that such demand is inelastic to income in the short run, but elastic in the long run. The parameter estimated for a substitute factor to the energy was not significant, indicating that there is no close substitute for electricity in the Industrial sector. This fact...
