Moreover, we shall argue that, as the economy was neither constrained by foreign exchange nor by the general scarcity of labor or capital, these changes in macroeconomic policy led to a substantial decrease in the rate of growth of aggregate demand and are chiefly responsible for the lower growth of both output and business investment

We will show that, unlike the scarce empirical work that investigated this relation for the Brazilian economy and does not confirm this empirical result, our estimates suggest the covered interest parity theorem holds for Brazilian data. Thus, a byproduct of this work is the evaluation of the characteristics of the Brazilian data and the variables used to estimate the covered parity. We argue that the relevantforeign interest ratevariable to test the CIP in Brazil is that one available to domestic agents, whose proxy is the LIBOR rate plus the Brazilian EMBI+ (the spread between the Brazilian sovereigndebt and the US treasury bonds rate), and we will compare this rate with the Brazilian foreign exchange coupon (which is a tautological closure to the covered parity), which is an alternative way to evaluate the covered parity in Brazil.

Research paper thumbnail of Keynesian Roots of Interest Parity Theorems

Interest parity theorems, namely the covered interest parity (CIP), uncovered interest parity (UI... more Interest parity theorems, namely the covered interest parity (CIP), uncovered interest parity (UIP) and real interest parity (RIP), as part of the basic open macroeconomics framework, are presented in almost every textbook in macroeconomics and international economics. This set of theorems explain how international capital flows make it impossible for a monetary authority to autonomously set their basic real interest rate in relation to the international one. In this work we will trace back the development of these theorems. We argue that although some post-Keynesians nowadays reject uncovered and real interest parities, even in the long period, these interest parity theorems have a Keynesian root. Covered Interest Parity first appears in Keynes 1923s’ A Tract on Monetary Reform. Uncovered Interest Parity theorem relies on early contributions from Keynes (1936), Kaldor (1939) and Tsiang (1958). But it is only during the 70’s, along with the diminished influence of keynesian theory, that other elements such as Rational Expectations and the Efficient Market Hypothesis are incorporated in this open economy framework and together with the PPP lead to the Real Interest Parity. Moreover, during the development of these theorems some interesting questions were tackled such as the role of speculation in destabilizing a floating exchange rate regime and the possibility of setting autonomously real interest rates across countries. Finally, we briefly summarize themain results obtained by the vast empirical literature. While there is great evidence in favor of the CIP, the results known as “UIP failure” and “forward premium puzzle” represent the persistent difficulty to falsify the UIP empirically.

Our results endorse the empirical failure of this theorem, known in the literature as UIP Failure or Forward Premium Puzzle. The coefficient estimated of the interest rate differential by a GARCH model is negative, contradicting UIP tests for emerging economies. However, using Markov models of regime change, we found two well-defined patterns: during periods of lower volatility the estimated coefficient becomes negative, while in the volatility periods estimated coefficient is positive. The results are consistent with the exogenous interest rate approach in an open economy.
