Sheep in Wolf’s Clothing: Using the Least Squares Criterion for Quantile Estimation
Estimation of the quantile model, especially with a large data set, can be computationally burdensome. This paper proposes using the Gaussian approximation, also known as quantile coupling, to estimate a quantile model. -
Rollover Risk, Liquidity and Macroprudential Regulation
I study rollover risk in the wholesale funding market when intermediaries can hold liquidity ex ante and are subject to fire sales ex post. -
Understanding the Cash Demand Puzzle
We develop a model to explain a puzzling trend in cash demand in recent years: the value of bank notes in circulation as a percentage of GDP has remained stable despite decreasing cash usage at points of sale owing to competition from alternative means of payment such as credit cards. -
Monetary Policy Transmission during Financial Crises: An Empirical Analysis
This paper studies the effects of a monetary policy expansion in the United States during times of high financial stress. The analysis is carried out by introducing a smooth transition factor model where the transition between states (“normal” and high financial stress) depends on a financial conditions index. -
Consumer Cash Usage: A Cross-Country Comparison with Payment Diary Survey Data
We measure consumers’ use of cash by harmonizing payment diary surveys from seven countries. The seven diary surveys were conducted in 2009 (Canada), 2010 (Australia), 2011 (Austria, France, Germany and the Netherlands), and 2012 (the United States). -
High-Frequency Trading Competition
We analyze trading dynamics as successive high-frequency trading (HFT) firms begin to trade stocks in an equity market. Entrants compete with incumbents for volume, and there is crowding out. -
Interest on Cash, Fundamental Value Process and Bubble Formation on Experimental Asset Markets
We study the formation of price bubbles on experimental asset markets where cash earns interest. There are two main conclusions. -
Multiple Fixed Effects in Binary Response Panel Data Models
This paper considers the adaptability of estimation methods for binary response panel data models to multiple fixed effects. It is motivated by the gravity equation used in international trade, where important papers such as Helpman, Melitz and Rubinstein (2008) use binary response models with fixed effects for both importing and exporting countries. -
E-Money: Efficiency, Stability and Optimal Policy
What makes e-money more special than cash? Is the introduction of e-money necessarily welfare enhancing? Is an e-money system necessarily stable? What is the optimal way to design an efficient and stable e-money scheme?
