Abstract

A series of relatively high inflation characterize Indonesian economy, especially during the economic crisis. Economists generally agree that high inflation is one of the major economic problems, and that economic authorities need to cope with such a problem. Therefore, it is essential to understand the behavior of inflation in Indonesia. The aim of this paper is to estimate the inflation dynamics in Indonesia using equilibrium correction and forward-looking Phillips Curve approaches. Previous empirical studies show that the equilibrium correction or backward-looking approach may explain the inflation dynamics in Indonesia. The backward-looking specification does not have to be the proper model even if the fact shows that the specification holds. The major innovation of this paper is the application of a forward-looking Phillips curve model. The empirical results—estimated using the Generalized Method of Moments (GMM)—show that the forward-looking Phillips Curve approach dominates the backward-looking behavior. It indicates that after a credible monetary policy announcement, for instance, the former model predicts that economic agents will change their behavior quickly. Therefore, the policy will affect the economy more rapidly

Abstract

The implementation of a deposit insurance scheme entails a trade off. On one hand, as shown in theoretical and empirical studies, a deposit insurance scheme reduces the likelihood of a bank run. On the other hand, a deposit insurance scheme induces moral hazard among bankers that may lead to bank failures. We rigorously test the effect of different deposit coverage limit and the implementation of a differential premium treatment on bankers’ behaviors in the deposit and credit market. We do so by designing a laboratory experiment that involves real bankers as participants. We find that the coverage limit treatments do not have any effect on deposit rate offer. Nevertheless, we find that a high deposit coverage limit induces smaller banks to have a higher share of risky projects. This is evidence of moral hazard particularly among small banks.

Abstract

Introduction/Main Objectives: This research aims to explore and analyze the effect of the COVID-19 pandemic on mental health status as measured by DASS-21. Background Problems: The prolonged impact of the COVID-19 pandemic on the global economy may have adversely affected mental health. A decrease in income and consumption and the uncertainties surrounding job security and business performance have been some of the main factors contributing to mental health issues. Novelty: This paper aims to evaluate the effect of the COVID-19 pandemic—as a natural experiment—on mental health measured by DASS-21 and how the effect of the pandemic varied across different socioeconomic subgroups. Research Methods: We conducted an online survey across Indonesia to collect self-reported mental health status and socioeconomic characteristics before and during the COVID-19 pandemic to measure its impacts on mental health. Finding/Results: Our results suggest that the COVID-19 pandemic has had an adverse impact on mental health, particularly in terms of anxiety and stress. The effect has been higher among individuals with lower self-efficacy, lower expenditure, and lower education levels. Conclusion: The health and economic crisis driven by the COVID-19 pandemic affected individuals' mental health, suggesting the need for appropriate policy responses.
