MODELING THE NONLINEAR FISCAL REACTION FUNCTION IN MALAYSIA

<jats:p> The fiscal reaction function (FRF) provides valuable insights into a country’s fiscal sustainability and output stability. However, there is no consensus yet on how to model it. Thus, this study investigates the best functional form for the FRF by adopting a nonlinear autoregressive distributed lag approach that accounts for a potential structural break in the data across periods. We examine the case of Malaysia and address the country’s data by using a break-point of the unit root test. The test results indicate the presence of a structural break in the country’s FRF. Moreover, the primary balance of Malaysia has an asymmetrical reaction to the country’s public debt and the output gap. This result suggests that a nonlinear behavior of FRF with a structural break is an accurate approach for the fiscal authority in Malaysia (for example, the Ministry of Finance) in designing prudent fiscal policy. This study finds that an asymmetric fiscal reaction in Malaysia neither guarantees fiscal sustainability nor supports output stability, thus suggesting the need for an independent fiscal council to promote prudent fiscal policy. </jats:p>
