Two forces have reshaped global securities markets in the last decade: Exchanges operate at much faster speeds and the trading landscape has become more fragmented. In order to analyze the positive and normative implications of these evolutions, we study a framework that captures (i) exchanges'...

A fundamental objective of the Doha Round of WTO negotiations is to improve the trading prospects of developing countries. The 2001 declaration from the WTO Ministerial Conference in Doha, Qatar, commits the member governments to negotiations aimed at substantial improvements in market access...

A modest approximation by homebuyers leads house prices to display three features that are present in the data but usually missing from perfectly rational models: momentum at one-year horizons, mean reversion at five-year horizons, and excess longer-term volatility relative to fundamentals....

This paper investigates how tax changes for different income groups affect aggregate economic activity. I construct a measure of who received (or paid for) tax changes in the postwar period using tax return data from NBER's TAXSIM. I aggregate each tax change by income group and state. Variation...

“Consumer-Directed” Health Plans (CDHPs) combine high deductibles with personal medical accounts and are intended to reduce health care spending through greater patient cost sharing. Prior research shows that CDHPs reduce spending in the first year. However, there is little research on the...

We propose a generalization of the linear quantile regression model to accommodate possibilities afforded by panel data. Specifically, we extend the correlated random coefficients representation of linear quantile regression (e.g., Koenker, 2005; Section 2.6). We show that panel data allows the...

Evaluations of workfare programs in poor rural economies have typically ignored two features that policy makers stress: involuntary unemployment and the expected welfare losses from work requirements. The paper generalizes past evaluation theory and methods to incorporate both features, and...

Job losses during the Great Recession were concentrated among middle-skill workers, the same group that over the long run has suffered the most from automation and international trade. How might long-run occupational polarization be related to cyclical changes in middle-skill employment? We find...

Since the 2008 global financial crisis, and after decades of relative neglect, the importance of the financial system and its episodic crises as drivers of macroeconomic outcomes has attracted fresh scrutiny from academics, policy makers, and practitioners. Theoretical advances are following a...

The well-known uncovered interest parity puzzle arises from the empirical regularity that, among developed country pairs, the high interest rate country tends to have high expected returns on its short term assets. At the same time, another strand of the literature has documented that high real...
