| 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... |

| 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. |

| 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... |

| 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... |
