Recent studies of conditional factor models do not specify conditioning information but use data from small windows to estimate the time series of conditional alphas and betas. In this paper, we propose a nonparametric method using an optimal window to estimate time-varying coefficients. In...

We document a new stylized fact regarding the dynamics of the commodity convenience yield: the volatility of the convenience yield is heteroskedastic for industrial commodities; specically, the volatility (variance) of the convenience yield depends on the convenience yield level. To explore the...

We propose a modified version of the Amihud illiquidity measure, AdjILLIQ, which performs well in different types of emerging markets. Our AdjILLIQ measure combines the virtues of the original Amihud ratio and the non-trading-frequency measure. It exhibits higher correlation with spread and...

Consistent with recent theoretical models where binding capital constraints lead to sudden liquidity dry-ups, we find that negative market returns decrease stock liquidity, especially during times of tightness in the funding market. The asymmetric effect of changes in aggregate asset values on...

We argue and provide evidence that stock price synchronicity affects stock liquidity. Under the relative synchronicity hypothesis, higher return co-movement (i.e., higher systematic volatility relative to total volatility) improves liquidity. Under the absolute synchronicity hypothesis, stocks...

We conduct a comprehensive analysis of the New York Stock Exchange (NYSE) limit order book at both the aggregate market level and the individual stock level based on a sample covering all the NYSE ordinary stocks. By providing detailed description of the limit order book, we show that it...

We provide a simple theoretical analysis based on Kyle's (1985) framework, and demonstrate how stock price synchronicity can affect the adverse information risk that market makers face and therefore the liquidity of the stock. Our empirical evidence is consistent with our theoretical conjecture....

Consistent with recent theoretical models where binding capital constraints lead to sudden liquidity dry-ups, we find that negative market returns decrease stock liquidity, especially for high volatility stocks and during times of tightness in the funding market. The asymmetric effect of changes...
