The impact of COVID‐19 pandemic on the Thai economy and the effectiveness of monetary policy: A Bayesian DSGE model approach

Abstract

AbstractThis study estimates a medium‐scale dynamic stochastic general equilibrium model for the Thai economy to evaluate the impact of the COVID‐19 pandemic containment policy on key macroeconomic aggregates. The shock to labor supply is considered as the main transmission channel. The paper discussed the role of monetary policy in regard to economic recovery and also identified the dominant shocks driving the business cycle. Thai quarterly series from 2011Q1 to 2021Q2 is used for the Bayesian estimation of the model. Though the pandemic shock caused a sharp decline in output, consumption and investment, the results suggest a fast recovery in the growth rates of the variables in about 2.5 years. At the same time, the dominant shocks that account for output variation in the medium to long term are investment, labor supply and productivity shocks. Monetary policy is effective in shortening the recovery due to its impact on private investment. The key drivers of Thai household consumption in the long run are investment, labor supply and productivity shocks. On average, the investment shock appears to be the key driver of the business cycle at all horizons.
