Expectations and exchange rates in a Keynes–Harvey model: an analysis of the Brazilian case from 2002 to 2017
This paper investigates the statistical relationship between the future expectations of the exchange rate and GDP growth and the current nominal exchange rate in Brazil during the period 2002–2017. The theoretical framework on which the paper is based is a decision-making model grounded in Keynes (1921; 1936) and Harvey (2006; 2009a), from which the paper's empirical model emerges. This model is tested empirically with autoregressive distributed lag models to identify short- and long-term statistical relationships in time series. The empirical estimations suggest that expectations of future changes in both the exchange rate and GDP growth have a statistically significant relationship with the current nominal exchange rate in Brazil, just as the Keynes–Harvey model predicts.
期刊介绍:
The Review of Keynesian Economics (ROKE) is dedicated to the promotion of research in Keynesian economics. Not only does that include Keynesian ideas about macroeconomic theory and policy, it also extends to microeconomic and meso-economic analysis and relevant empirical and historical research. The journal provides a forum for developing and disseminating Keynesian ideas, and intends to encourage critical exchange with other macroeconomic paradigms. The journal is dedicated to the development of Keynesian theory and policy. In our view, Keynesian theory should hold a similar place in economics to that held by the theory of evolution in biology. Many individual economists still work within the Keynesian paradigm, but intellectual success demands institutional support that can leverage those individual efforts. The journal offers such support by providing a forum for developing and sharing Keynesian ideas. Not only does that include ideas about macroeconomic theory and policy, it also extends to microeconomic and meso-economic analysis and relevant empirical and historical research. We see a bright future for the Keynesian approach to macroeconomics and invite the economics profession to join us by subscribing to the journal and submitting manuscripts.
