Evidence is presented on the Real Interest Parity Hypothesis for a set of emerging and developed countries. This is done by carrying out a set of unit-root tests on the real interest differentials with respect to Germany and the US. Our results support the hypothesis of a rapid reversion towards...

The variance of real interest rate differentials (rids) is decomposed between ex post deviations from relative purchasing power parity and uncovered interest rate parity (UIRP) for a set of emerging markets from 1995M5 to 2004M3. The results point out to nominal interest rate differentials and...

We test the degree to which presidential approval ratings are related to a series of economic indicators, controlling for the political scenario in Brazil. Results, from 1999M9 until 2010M5, show that unemployment and the minimum wage are the main variables that affect the ratings. There is also...

We propose a discrete choice model of socially interacting consumers choosing between two product variants. The model shows that the discontinuity of demand as well as the demand polarization proposed by Becker (1991), A Note on Restaurant Pricing and Other Examples of Social Influences on...

We test ex ante uncovered interest parity (UIP) for Brazil using survey data of ex- change rate expectations from the Brazilian Central Bank. Using data from 2001M11 until 2007M12 and Ordinary Least Squares, we found that the estimated UIP parameter is smaller than one, which is a common...

Contrary to the predictions of the theory underlying international finance, inflows of capital triggered by financial liberalisation have neither equalised real interest rates nor increased income growth in many emerging economies. We explain this puzzle by developing a model that combines the...

We build a model that incorporates the effect of the innovative "flex" car, an automobile that is able to run with either gasoline or alcohol, on the dynamics of fuel prices in Brazil. Our model shows that differences regarding fuel prices will now depend on the proportions of alcohol, gasoline...
