The Threat of Counterfeiting in Competitive Search Equilibrium
Recent studies in monetary theory show that if buyers can use lotteries to signal the quality of bank notes, counterfeiting does not occur in a pooling equilibrium. In this paper, I investigate the robustness of this non-existence result by considering an alternative trading mechanism. -
Why Do Emerging Markets Liberalize Capital Outflow Controls? Fiscal versus Net Capital Flow Concerns
In this paper, we provide empirical evidence on the factors that motivated emerging economies to change their capital outflow controls in recent decades. Liberalization of capital outflow controls can allow emerging-market economies (EMEs) to reduce net capital inflow (NKI) pressures, but may cost their governments the fiscal revenues that external financial repression generates. -
Money Market Rates and Retail Interest Regulation in China: The Disconnect between Interbank and Retail Credit Conditions
Interest rates in China are composed of a mix of both market-determined interest rates (interbank rates and bond yields), and regulated interest rates (retail lending and deposit rates), reflecting China’s gradual process of interest rate liberalization. -
Business Cycle Effects of Credit Shocks in a DSGE Model with Firm Defaults
This paper proposes a theoretical framework to analyze the relationship between credit shocks, firm defaults and volatility, and to study the impact of credit shocks on business cycle dynamics. -
Booms and Busts in House Prices Explained by Constraints in Housing Supply
We study the importance of supply constraints in explaining the heterogeneity in house price cycles across geographies in the United States. -
Fire-Sale FDI or Business as Usual?
Using a new data set, we examine the characteristics and dynamics of cross-border mergers and acquisitions during emerging-market financial crises, that is, so-called “fire-sale FDI.” Our findings shed fresh light on whether the transactions undertaken during crisis periods differ in fundamental ways from those undertaken during more tranquil periods. -
Multivariate Tests of Mean-Variance Efficiency and Spanning with a Large Number of Assets and Time-Varying Covariances
We develop a finite-sample procedure to test for mean-variance efficiency and spanning without imposing any parametric assumptions on the distribution of model disturbances. -
What Central Bankers Need to Know about Forecasting Oil Prices
Forecasts of the quarterly real price of oil are routinely used by international organizations and central banks worldwide in assessing the global and domestic economic outlook, yet little is known about how best to generate such forecasts. Our analysis breaks new ground in several dimensions. -
Are Sunspots Learnable? An Experimental Investigation in a Simple General-Equilibrium Model
We conduct experiments with human subjects in a model with a positive production externality in which productivity is a non-decreasing function of the average level of employment of other firms.
