Measuring the Long Run Real Exchange Rate – Income Relationship

Yanping Chong, Oscar Jorda and Alan M. Taylor have tackled the perennial challenge of measuring the long run relationship between the real exchange rate and per capita income levels. From the abstract to The Harrod-Balassa-Samuelson Hypothesis: Real Exchange Rates and their Long-Run Equilibrium:

Frictionless, perfectly competitive traded-goods markets justify thinking of purchasing power parity (PPP) as the main driver of exchange rates in the long-run. But differences in the traded/non-traded sectors of economies tend to be persistent and affect movements in local price levels in ways that upset
the PPP balance (the underpinning of the Harrod-Balassa-Samuelson hypothesis, HBS). This paper uses panel-data techniques on a broad collection of countries to investigate the long-run properties of the PPP/HBS equilibrium using novel local projection methods for cointegrated systems. …

A Still Relevant GAO Classic: Floating Exchange Rates in an Interdependent World and “Overvaluation”

Following up on my misalignment post from Tuesday, here’s a volume compiled by the GAO when it was the General Accounting Office containing a symposium on exchange rates. The symposium took place in the midst of currency overvaluation: “Floating Exchange Rates in an Interdependent World”. The authors included Richard Cooper, Stanley Black, Rudiger Dornbusch, Jeffrey Frankel, and Jacob Frenkel.

The Dollar in Doubt?

I’ve found it puzzling that there’s all this talk about the prospects for the dollar, in the wake of the G-20 meetings, and more recently World Bank President Zoellick’s comments about the primacy of the dollar as a reserve currency. My puzzlement arises from the fact that many of the concerns now being voiced have been voiced before.

Exchange Rates: New Papers

During the summer, I had the good fortune to attend two excellent conferences focused on new findings in exchange rate economics (yes, not all economic research is focused on the financial crisis and recession). The first was a Bank of Canada-European Central Bank conference Exchange rates: The global perspective, and the second was the NBER International Finance and Macroeconomics Summer Institute session “Exchange Rates and Relative Prices”.

ZIRP and the exchange rate…and other macro variables

Several months ago, I discussed the implications of a model of the exchange rate wherein Taylor rule fundamentals — the output [0], inflation and exchange rate gaps — were central (post). In that paper [pdf], I showed that Taylor rule fundamentals outperformed purchasing power parity, interest rate parity, and the monetary model of exchange rates in terms of in-sample fit, at least insofar as the dollar/euro exchange rate is concerned.

Measuring Import Prices: Implications for GDP Growth

A lot of what has happened to GDP growth over the past few quarters has, in a mechanical sense, depended upon developments in the external accounts. In this post, I examine whether mismeasurement of import prices might have induced mismeasurement of economic output. This idea was prompted by hearing a presentation of Nakamura and Steinsson a couple months ago. The abstract to “Lost in Transit: Product Replacement Bias and Pricing to Market”:
