This paper provides a theoretical underpinning for the major determinants of optimal reserve demand in the case where fundamental disequilibrium constitutes a key element governing reserve management. Emphasis is given to the role of reserves to smooth the process of economic adjustment by...

This paper proposes a dynamic stochastic general equilibrium model that endoge­nously generates inflation persistence. We assume that although firms change prices periodically, they face convex costs that preclude optimal adjustment. In essence, the model assumes that price stickiness arises...

This paper investigates the issue of rational expectations using inflation forecasts from the Survey of Professional Forecasters (SPF) and the Green Book. We provide an alternative test of rational expectations hypothesis by measuring the degree of persistence of potential systematic mistakes....

This study examines the impact of credit constraints on the term premium in a production economy. To do so, we incorporate the Kiyotaki-Moore collateral constraint and Epstein-Zin-Weil preferences into a medium-scale New Keynesian Dynamic Stochastic General Equilibrium (NK DSGE) model with...

Korean Abstract: 경기변동을 설명함에 있어 재화시장의 가격경직성과 함께 임금경직성이 중요하다는 인식이 확대됨에 따라 통화정책에서 차지하는 실업률의 역할 또한 증대되고 있다. 반면, 전통적인 확률적 동학 일반균형(DSGE)...

Korean Abstract: 글로벌 금융위기에 대응하면서 주요국 중앙은행은 정책금리를 제로수준까지 대폭 인하하고 양적완화(quantitative easing) 등 비전통적 통화정책을 도입하였다. 아울러 이러한 비전통적 통화정책이...

We study a fundamental difference between the Bernanke, Gertler, and Gilchrist (BGG, 1999) model and the models with collateral constraints of Kiyotaki and Moore (1997) and Iacoviello (2005). The BGG model implies that the loan-to-value (LTV) ratio is mainly determined by factors affecting...

This paper examines the impact of global supply chain disruptions and the associated uncertainty on economic activity and inflation. We employ a Bayesian VAR model with the Global Supply Chain Pressure Index (GSCPI) and estimated uncertainty to analyze their effects during the pandemic. Our...

This paper investigates wage dynamics assuming the potential presence of dual wage stickiness: with respect to both the frequency as well as the size of wage adjustments. In particular, this paper proposes a structural model of wage inflation dynamics assuming that although workers adjust wage...
