Examining Inflation Expectations within Asian Economies: Application of Wavelet Quantile Analysis towards Assessing Monetary Policy Credibility

Abstract

The relevance of rational expectations has generated a renewed interest in assessing the accuracy of monetary policy declarations. Despite the enduring principles of the rational expectations theory, a remarkably dependable central bank can alleviate inflation by skillfully managing inflation expectations, thus avoiding adverse effects on employment. This paper explores the complex relationship between inflation expectations, target inflation rates, and the credibility of monetary policy, emphasizing the importance of rule compliance and transparent communication for establishing public confidence in central banks. While the estimation processes the study utilizes wavelet-based quantile regression by investigating data from 1990q1 to 2021q4, with variations across selected countries. The credibility index (CI) is employed to instrument the dependability of monetary policies. Nevertheless, the results of this study indicate that Policy credibility has a significant impact on inflation expectations in Bangladesh and Sri Lanka, underscoring the importance of clear communication and institutional reforms. Different outcomes in India and considerable effects in Pakistan underscore the necessity of customized policy measures and communication strategies to address inflation and promote economic stability in South Asia.
