O regime de metas inflacionárias e sua adequação à economia brasileira

The Inflation Targeting Regime was adopted in Brazil in 1999 and it aims at maintaining the price level in the interval set by the government. For such reason, the Central Bank makes use of variations in the interest rate, which causes the cost of the credit to be more expensive, reducing the investments, the jobs and, concomitantly, the inflation. Being aware that the country is subject to sudden reversals of the international capital flows which results in exchange rate and price instability, an econometric analysis of the adequation of the targerting regime to the Brazilian economy, especially concerned with the index price that is used as the parameter for the inflation calculus, is proposed

A taxa de câmbio do Brasil é válida no longo prazo?

The objective of this study was to test the validity of the real exchange rate in the long run. For that five tests were performed based on equation, which relates to real exchange rate, international trade, domestic income. The main difference is that the tests when we are working with quarterly data, the parameters are significantly different from zero – i.e., the variables real exchange rate, international trade, domestic income and net exports on long term relationship – and, moreover, the signs are as expected. This implies that it is possible to increase exports with currency devaluation. Thus, based on data and tests that work we conclude that the exchange rate is an important instrument of trade policy, given that devaluations are valid even in the long term.

Restrição externa e taxa de câmbio no Brasil: 1980-2008

The objective of this study is to examine if economic growth in Brazil was blocking due to external constraints, that is, in consequence of its Balance of Payments. We work with the approach first proposed by Thirlwall (1979) which was later modified by Lima and Carvalho (2009). We can conclude that economic growth was restricted by the external sector, which is consistent with the economic history of Brazil, and verify that the real exchange rate, and to influence the trade balance in the course run, also excerce some influence on this account balance of payments in the long run.

Analysis of metabolic pools in broilers chicks

This paper shows the possibility of obtaining new parameters for the mathematical modelling of data on stable isotopes in biological systems and its application in obtaining data on metabolic pools of blood plasma, blood serum, liver and muscle of broilers. This theory states that the modelling of turnover used for studies of isotopic incorporation when the metabolism has a single metabolic pool is feasible by the technique of setting an exponential. However, when the metabolism has more than one metabolic pool, it is necessary to apply the linearization technique, linear regression adjustment and evaluation of the assumptions of regression to obtain the kinetic parameters such as half-life (T1/2) and isotope exchange rate (k). The application of this technique on carbon-13 data from 100 one-day-old chicks, with the change of diet composed of grains of the photosynthetic cycle of plants from C4 to C3, in broilers has enabled the discovery that the liver, blood plasma and blood serum have a single metabolic pool; however, the pectoral muscle has two metabolic pools. For the liver, blood plasma and blood serum, the half-life values were found by the exponential fit being T1/2 = 1.4 days with the rate of exchange of k = 0.502, T1/2 = 2.4 days with k = 0.293 and T1/2 = 2.0 days with k = 0.348, respectively. For the pectoral muscle, after linearization, the half-life values were found for T1/2(1) = 1.7 and T1/2(2) = 3 days, with exchange rates of k1 = 0.405 and k2 = 0.235, representing approximately 66 and 34 %, respectively.
