Taxa real de câmbio, desalinhamento cambial e crescimento econômico no Brasil (1994-2007)

Real exchange rate, exchange rate misalignment and economic growth in Brazil: 1994-2007. In this article we argue that the Brazilian economy presented in the period 1994-2007 a tendency of real exchange rate appreciation with respect to its equilibrium value, mainly from 2005. This exchange rate misalignment has worked to reduce the growth of Brazilian economy and is the root of the re-emergence of current account deficits.

Metas de inflação, taxa de câmbio real e crise externa num modelo kaleckiano

Inflation target, real exchange rate and external crisis in a Kaleckian model. Which role should the real exchange rate play in an inflation target regime? In this paper this point is discussed from the point of view of the conditions required for avoiding an external crisis. With this objective, a dynamic Kaleckian model is presented focusing on the stability of the external debt to capital ratio. The main conclusion is that policy makers should monitor closely the evolution of the real exchange rate in order to make compatible the inflation target regime with external stability.

Exchange rate pass-through inflation and wage differentials in late-industrializing economies: the Mexican case

This paper investigates exchange rate pass-through inflation, and the wage bargaining process, in a developing economy in which firms' market power is largely dependent on technical progress embodied in imported intermediates and capital goods. It develops a heterodox model of income distribution, based on theoretical contributions from Latin American structuralists, labor market segmentationists and post-Keynesian writers, and it presents supportive empirical evidence from the Mexican economy.

Overvaluation trend of the Brazilian currency in the 2000s: empirical estimation

The aim of this paper is to discuss the trend of overvaluation of the Brazilian currency in the 2000s, presenting an econometric model to estimate the real exchange rate (RER) and which should be a reference level of the RER to guide long-term economic policy. In the econometric model, we consider long-term structural and short-term components, both of which may be responsible for explaining overvaluation trend of the Brazilian currency. Our econometric exercise confirms that the Brazilian currency had been persistently overvalued throughout almost all of the period under analysis, and we suggest that the long-term reference level of the real exchange rate was reached in 2004. In July 2014, the average nominal exchange rate should have been around 2.90 Brazilian reais per dollar (against an observed nominal rate of 2.22 Brazilian reais per dollar) to achieve the 2004 real reference level (average of the year). That is, according to our estimates, in July 2014 the Brazilian real was overvalued at 30.6 per cent in real terms relative to the reference level. Based on these findings we conclude the paper suggesting a mix of policy instruments that should have been used in order to reverse the overvaluation trend of the Brazilian real exchange rate, including a target for reaching a real exchange rate in the medium and the long-run which would favor resource allocation toward more technological intensive sectors.

Institutions, credibility and crisis: the inconsistencies of Argentine exchange rate policy (1991-2006)

The purpose of this article is twofold. The first is to explain the time inconsistencies of the convertibility regime that led to the 2001 crisis. The argument suggests that the credibility requirements for convertibility induced a dynamic of legal, fiscal, financial and external commitments that increased exit costs and time inconsistencies. The second objective is to explain the tensions of the floating regime that replaced convertibility in 2002. We describe the effects of a floating exchange rate on macroeconomic imbalance and the growing tension between competitiveness and inflation.

Explaining the Transition Between Exchange Rate Regimes

This paper studies the transition between exchange rate regimes using a Markov chain model with time-varying transition probabilities. The probabilities are parameterized as nonlinear functions of variables suggested by the currency crisis and optimal currency area literature. Results using annual data indicate that inflation, and to a lesser extent, output growth and trade openness help explain the exchange rate regime transition dynamics.

Media bias and central bank response. Evidence from the nominal exchange rate behavior in Colombia

Since 1991 Colombia has had a market-determined Peso - US Dollar Nominal Exchange Rate (NER), after more than 20 years of controlled and multiple exchange rates. The behavior (revaluation / devaluation) of the NER is constantly reported in news, editorials and op-eds of major newspapers of the nation with particular attention to revaluation. The uneven reporting of revaluation episodes can be explained by the existence of an interest group particulary affected by revaluation, looking to increase awareness and sympathy for help from public institutions. Using the number of news and op-eds from a major Colombian newspaper, it is shown that there is an over-reporting of revaluation episodes in contrast to devaluation ones. Secondly, using text analysis upon the content of the news, it is also shown that the words devaluation and revaluation are far apart in the distribution of words within the news; and revaluation is highly correlated with words related to: public institutions, exporters and the need of assistance. Finally it is also shown that the probability of the central bank buying US dollars to lessen revaluation effects increases with the number of news; even though the central bank allegedly intervenes in the exchange rate market only to tame volatility or accumulate international reserves.

Piecemeal Oligopoly, Exchange Rate Uncertainty, and Trade Policy.

Este artículo analiza el efecto sistemático de la volatilidad de la tasa de cambio, cuando un gobierno local debe evaluar políticas comerciales estratégicas lineales y cuadráticas. Este ejercicio se realiza para modelos de mercado Cournot y Bertran. El modelo prueba que tanto el esquema lineal como el cuadrático tienen el mismo efecto sobre el bienestar social de los países, y que la volatilidad de la tasa de cambio domestica lleva a los gobiernos a reducir los subsidios a las exportaciones o bajan los impuestos a las exportaciones, de acuerdo a la variable estratégica elegida por las firmas. La tasa de cambio extranjera tiene diferentes efectos dependiendo de si las firmas producen bajos rendimientos a escalas constantes o decrecientes.
