Real Effective Exchange Rate

The real effective exchange rate (REER) is the exchange rate of a country’s currency against a weighted combination of other currencies, adjusted for relative consumer prices, and reflects the overall competitiveness of the country.

Background

The Real Effective Exchange Rate (REER) is a critical concept in international economics and finance, measuring a country’s currency value versus a basket of other currencies. Adjusted for the different inflation rates between trading partners, this metric indicates a country’s competitiveness in the global market.

Historical Context

The concept of the REER emerged as global trade and investment became more complex in the 20th century. Unlike bilateral exchange rates, the REER encompasses multiple trading partners, reflecting globalization trends and the intricacies of multinational economic relationships.

Definitions and Concepts

The Real Effective Exchange Rate (REER) is defined as the exchange rate between a country’s currency and a weighted combination, or basket, of other countries’ currencies, taking into account relative consumer prices. The weights are based on the countries’ relative trade balances.

Major Analytical Frameworks

Classical Economics

Classical economics primarily focuses on absolute or comparative advantage, contributing to early understandings of exchange rates without considering advancements that the REER encompasses.

Neoclassical Economics

In neoclassical economics, the REER is analyzed in terms of market forces of supply and demand, where adjustments reflect purchasing power parity (PPP). The REER accounts for both nominal exchange rates and consumer price indices.

Keynesian Economics

Keynesian economics looks at the REER concerning fiscal policies and overall economic activity. Currency value adjustments in the REER would be seen in the context of aggregate demand shifts.

Marxian Economics

Marxian analysis might relate the REER to global labor value and capital movements, observing discrepancies in international prices and standards of living.

Institutional Economics

This school would examine how institutions, policies, and regulations impact the REER, considering variations among countries with different trade policies and economic structures.

Behavioral Economics

Behavioral economics highlights how perceptions and behaviors of market participants impact the REER, considering factors like consumer trust, expectations, and decision-making biases.

Post-Keynesian Economics

In post-Keynesian economics, the focus might be on real economic variables like investment and production alongside the REER, emphasizing the policy implications and active government roles.

Austrian Economics

Austrian economists might analyze REER from the standpoint of currency competition, market dynamics, and inflation differences due to decentralized decision-making processes.

Development Economics

In development economics, the REER is crucial for understanding how emerging economies’ trade competitiveness evolves against established economies, emphasizing the role of balance of payments and trade policies.

Monetarism

Monetarists would scrutinize the impact of monetary policies on aggregate inflation rates and subsequently on the REER, focusing on money supply and demand discipline.

Comparative Analysis

REER provides a more comprehensive measure compared to nominal exchange rates, encompassing multiple countries and adjusting for inflation differences. A higher REER suggests decreased competitiveness, while a lower REER indicates enhanced competitiveness.

Case Studies

  • Japan’s REER adjustment during periods of quantitative easing.
  • The impact of the Euro on EU member states’ REER.
  • China’s REER fluctuations and their relation to trade policy reforms.

Suggested Books for Further Studies

  • “Exchange Rate Economics: Theories and Evidence” by Ronald MacDonald
  • “International Economics: Theory and Policy” by Paul R. Krugman and Maurice Obstfeld
  • “The Economics of Exchange Rates” by Lucio Sarno and Mark P. Taylor
  • Nominal Exchange Rate: The rate at which one currency can be exchanged for another without adjusting for inflation differences.
  • Purchasing Power Parity (PPP): An economic theory used to compare countries’ currencies through their buying power in the respective contexts, often influencing REER.
  • Bilateral Exchange Rate: The direct rate of exchange between two specific countries’ currencies, not taking into account a broader basket of currencies.

This comprehensive examination of the Real Effective Exchange Rate provides insight into its integral role in global economic analysis, revealing the interconnectedness of international markets.
