Exchanges nowadays routinely operate multiple, almost identically structured limit order markets for the same security. We study the effects of such fragmentation on market performance using a dynamic model where agents trade strategically across two identically-organized limit order books. We...

We assess the consequences for market quality and welfare of different entry regimes and exchange pricing policies in a context of limited market participation. To this end we integrate a two-period market microstructure model with an exchange competition model with entry in which exchanges...

We propose a parsimonious measure based solely on daily stock returns to characterize the severity of microstructure frictions at the individual stock level and assess the impact of frictions on the cross section of stock returns. Stocks with the largest frictions command a value-weighted return...

From 1963 through 2015, idiosyncratic risk (IR) is high when market risk (MR) is high. We show that the positive relation between IR and MR is highly stable through time and is robust across exchanges, firm size, liquidity, and market-to-book groupings. Though stock liquidity affects the...

Regulators, exchanges, and politicians are considering reining in maker-taker pricing, which is used as a competitive tool by trading venues to acquire order flow. Examining the 2013 reduction in trading fees operated by BATS on its European venues, we document significant effects on market...

We study price and liquidity spillovers in U.S. stock markets around mutual fund fire sales. We find that the well-documented impact-reversal pattern for the returns of fire sale stocks (e.g., Coval and Stafford, 2007) spills over onto the stock returns of economic peers, with a magnitude that...

We develop an estimator for publication bias and apply it to 156 hedge portfolios based on published cross-sectional return predictors. Publication bias adjusted returns are only 12% smaller than in-sample returns. The small bias comes from the dispersion of returns across predictors, which is...

Since 1965, average idiosyncratic risk (IR) has never been lower than in recent years. In contrast to the high IR in the late 1990s that has drawn considerable attention in the literature, average market-model IR is 44% lower in 2013-2017 than in 1996-2000. Macroeconomic variables help explain...

Why is an inverted yield-curve slope such a powerful predictor of future recessions? We show that a decomposition of the yield curve slope into its expectations and risk premia components helps disentangle the channels that connect fluctuations in Treasury rates and the future state of the...

Purpose - The intervalling effect bias of beta refers to the sensitivity of beta estimation with respect to the reference time interval on which returns are measured and its manifestation may indicate the degree of market inefficiencies. The purpose of this paper is to study the intervalling...
