We study the effects of political uncertainty on commodity markets from both theoretical and empirical perspectives. Consistent with our theoretical predictions, commodity prices and inventories decline by 6.6% and 5.7%, respectively, and convenience yields increase by 1.9% in the quarter...

We show that the presence of high frequency trading (HFT) has significantly mitigated the frequency and severity of end-of-day price dislocation, counter to recent concerns expressed in the media. The effect of HFT is more pronounced on days when end of day price dislocation is more likely to be...

This paper studies the workup protocol, a unique trading feature in the U.S. Treasury securities market that resembles a mechanism for discovering dark liquidity. We quantify its role in the price formation process in a model of the dynamics of price and segmented order flow induced by the...

A short squeeze is triggered if there is pressure on short sellers to cover their positions because of a sharp price increase or a recall of borrowed shares. This drives short sellers to close their positions early. We find that stock-day short-squeeze events are rare and short-lived. However,...

In this paper, I identify a novel channel through which political beliefs affect investor behavior. Instead of considering differences of opinion between Republicans and Democrats, I analyze nonpartisan evaluations of the executive using Gallup's presidential approval ratings. I find that large...

Most corporate bond research on liquidity and dealer inventories is based on the USD-denominated bonds transactions in the US reported to TRACE. Some of these bonds, however, are also traded in Europe, and those trades are not subject to the TRACE reporting requirements. Leveraging our access to...

US government bond illiquidity measures began rising during the last week of February 2020. Several of them surpassed the Great Recession levels during the second week of March. Illiquidity spikes do not seem to match with proposed explanatory events. The illiquidity measures of the most...

In this paper I examine the relationship between credit rating and insider trading of 301 firms from 2000-2006 for S&P 500 Index firms. I argue that changes to the firm credit rating may increase (decrease) informed trading activities. This investigation is essential since insiders with private...

We study the workup protocol, an important size discovery mechanism in the U.S. Treasury securities market. We find that shocks in workup order flow explain 6-8 percent of the variation of returns on benchmark notes and, across maturities, contribute 10 percent to the variation of the yield...

This paper studies how the Baker, Bloom and Davis (2013) new measure capturing economic policy uncertainty (EPU) is related to stock market performance in the United States. We use a variety of methods to estimate different specifications. We find that an increase in the EPU index negatively...
