Ratios that indicate the statistical significance of a fund's alpha typically appraise its performance. A growing literature suggests that even in the absence of any ability to predict returns, holding options positions on the benchmark assets or trading frequently can significantly enhance...

This paper makes use of a natural experiment of the U.S. Treasury Department to examine the relationship between Treasury security issue size and liquidity. Treasury bills that were first issued with fifty-two weeks to maturity and then reopened at twenty-six weeks are shown to be more liquid...

This paper examines how risk in trading activity can affect the volatility of asset prices. We look for this relationship in the behavior of interest rate swap spreads and in the volume and interest rates of repurchase contracts. Specifically, we focus on convergence trading, in which...

Does the presence of arbitrageurs decrease equilibrium asset price volatility? I study an economy with arbitrageurs, informed investors, and noise traders. Arbitrageurs face a trade-off between arbitrage and inference: they would like to buy assets in response to temporary price declines (the...

Many of the features that make the Treasury market an attractive benchmark and...

The Term Securities Lending Facility (TSLF) was introduced by the Federal Reserve to promote liquidity in the financing markets for Treasury and other collateral. We evaluate one aspect of the program - the extent to which it has narrowed repo spreads between Treasury collateral and less liquid...

We find that the firms included in the S&P 500 index are characterized by large increases in earnings, appreciation in market value, and positive price momentum in the period preceding their index inclusion. This strong preinclusion performance predicts 1) the permanent increase in market value...

This paper is the first to document the presence of a private premium in public bonds. We find that spreads are 31 basis points higher for public bonds of private companies than for bonds of public companies, even after controlling for observable differences, including rating, financial...

In response to the sharp decline in prices of financial stocks in the fall of 2008, regulators in a number of countries banned short selling of particular stocks and industries. Evidence suggests that these bans did little to stop the slide in stock prices, but significantly increased costs of...

We develop a new likelihood-based approach to signing trades in the absence of quotes. This approach is equally efficient as the existing Markov-chain Monte Carlo methods, but more than ten times faster. It can address the occurrence of multiple trades at the same time and allows for analysis of...
