Big Mac Index reveals currency valuation differences in Chile and Colombia

According to The Economist’s Big Mac Index, significant price discrepancies exist for the same product across different nations. A Big Mac costs US$5.10 in Chile, US$8.00 in Colombia, and US$6.22 in the United States.

Based on the principle of purchasing power parity, these prices suggest the Chilean peso is undervalued by 18% against the dollar, while the Colombian peso is overvalued by 29%. While economic theory suggests arbitrage should equalize these prices, practical barriers such as local labor, rent, and non-tradable services prevent such rapid adjustments.

Research indicates that while currencies may correct deviations over several years, the index has limited short-term predictive power for exchange rate movements. Additionally, economist Gita Gopinath notes that because much international trade is conducted in dollars, local currency fluctuations do not always result in immediate price parity for imported goods.
