Determinantes da taxa de câmbio real no Brasil: 1971-2002

The theoretical and empirical international trade literature suggests that there is long-term valuation/devaluation of the real exchange rate in the developed/undeveloped economies. We argue that the real exchange rate is affected by: i) intercountry differentials of the services sector development; and, ii) non-neutral characteristic of the international financial system, demonstrated in the Post-Keynesian approach. An equation for the Brazilian real exchange rate was estimated in this paper (1971-2002) and the international liquidity variable and a proxy variable for the differentials of the services sector development were included in the equation. The econometric procedures were based on the Engle-Granger and Johansen methods. The results do not reject the hypothesis put forward in this paper.
