We re-examine the determinants of current account balances (CAB) and the saving-investment nexus with focus on emerging market and developing economies (EMDEs). We are in a new age in terms of facing not just economic challenges but also other non-economic challenges such as global climate...

Using comprehensive administrative data on Chilean firms, we examine whether credit lines and government-backed credit guarantees mitigated the impact of the large sudden stop event during the pandemic--the abrupt withdrawal of international capital. Our analysis employs a regression...

Are unregulated capital flows excessive during a stagflation episode? We argue that they likely are, owing to a macroeconomic externality operating through the economy's supply side. Inflows raise domestic wages through a wealth effect on labor supply and cause unwelcome upward pressure on...

This paper develops a framework to study the management of international reserves when a government faces the risk of a rollover crisis. In the model, it is optimal for the government to reduce its vulnerability by initially lowering debt, and then increasing both debt and reserves as it...

This paper investigates the implications of international financial sanctions for the reserve currency status of the US dollar. We propose a simple model of a reserve currency, demonstrate how the anticipation of financial sanctions can weaken the dollar's status, and evaluate the welfare...

Foreign investors' changing appetite for risk-taking have been shown to be a key determinant of the global financial cycle. Such fluctuations in risk sentiment also correlate with the dynamics of UIP premia, capital flows, and exchange rates. To understand how these risk sentiment changes...

The Global Financial Crisis and the COVID-19 pandemic were two major shocks to the world economy in the 21st century. In this study, we analyze the patterns of recessions and recoveries of 101 advanced and developing economies. We identify the turning points of recessions and expansions between...

Monetary theory and policy are part of intertemporal public finance. The lecture reviews some interesting recent developments. The two ghosts are the venerable liquidity trap and the Pigou effect or real balance effect. The eccentricities are negative nominal interest rates and the helicopter...

To help first- or second-year graduate students in economics apply their theoretical training, this paper shows how to solve a simple and intuitive computable general equilibrium (CGE) model using a calculator. Because this simplified Harberger model uses Cobb Douglas functional forms for...
