I explore the effects of trade-size dependent transaction taxes on market liquidity and information acquisition. Transaction taxes cause strategic informed traders to scale back their aggregate trading, which, surprisingly, causes both market liquidity and informed investor profits to decline in...

This paper examines ex ante effects of quot;circuit breakersquot; (mandated trading halts). We show that circuit breakers, by causing agents to suhoptimally advance trades in time, may have the perverse effect of increasing price variability and exacerbating price movements. We next consider a...

We show how a high degree of commonality in investor liquidity shocks can diminish incentives for intermediaries to keep markets open and lead to market collapse, even without information asymmetry or news affecting fundamentals. We motivate our model using the perpetual floating rate note...

We study the collapse of the market for perpetual floating rate notes (perps). The perp market was launched in 1984, and its first two years were characterized by explosive growth in which issues by high quality borrowers were placed with institutional investors and traded in liquid secondary...

We develop a new methodology that goes all-in machine learning to identify FinTech innovation, and, in turn, to construct a bank-specific proxy of such innovation in China. Since China stringently separates commercial (traditional) and investment banking services, this allows us to study the...

We study common determinants of daily bid-ask spreads and trading volume for the bond and stock markets over the 1991-98 period. We find that spread changes in one market are affected by lagged spread and volume changes in both markets. Further, spread and volume changes are predictable to a...

This paper examines the mechanism through which the incorporation of information into prices leads to cross-autocorrelations in stock returns. The lead-lag relation between large and small stocks increases with lagged spreads of large stocks. Further, order flows in large stocks significantly...

This paper explores liquidity movements in stock and Treasury bond markets over a period of more than 1800 trading days. Cross-market dynamics in liquidity are documented by estimating a vector autoregressive model for liquidity (that is, bid-ask spreads and depth), returns, volatility, and...

This paper explores liquidity spillovers in market-capitalization-based portfolios of NYSE stocks. Return, volatility, and liquidity dynamics across the small- and large-cap sectors are modeled by way of a vector autoregression model, using data that spans more than 3,000 trading days. We find...
