A Simultaneous-Equation Model of Estimating the Response of the Consumer Price to Exchange Rate Movements in Thailand

Abstract

This paper examines exchange rate pass-through (ERPT) to the consumer price in Thailand based on a simultaneous-equation model consisting of the IS, LM and AS function. It employs comparative static analysis to determine the impact of a change in an exogenous variable on the equilibrium price level. The paper finds that a 1% depreciation of the Thai baht tends to cause the CPI to rise by 0.0696% and has declined since the adoption of inflation targeting in 2000. In addition, more money supply, more government deficit as a percent of GDP, a higher crude oil price, a higher U.S. CPI, and a higher expected price tends to raise Thailand’s CPI. The findings suggest that in addition to the exchange rate, other relevant variables such as fiscal policy, monetary policy, the crude oil price, U.S. price level and the expected price level are expected to impact the consumer price level.
