The Kyle (1985) model is extended to take into account market maker competition and the spread. It is shown that with a spread the Kyle model has a Nash equilibrium also with two market makers, not only with three or more, as shown in earlier research. The spread is endogenized, and two testable...

Sudden big price changes are followed by periods of high and persistent volatility. I develop a tractable dynamic rational expectations model consistent with this observation. An infinity of agents possess dispersed information about future dividends and trade in centralized markets. Information...

Many empirical studies suggest that correlated demand is important in driving liquidity commonality among stocks. However, there are still no theoretical studies on how demandside factors cause and affect liquidity and return commonality. We propose a tractable equilibrium model with asymmetric...

This paper reviews, synthesizes, and critiques the capital market literature examining trading volume around earnings announcements and other financial reports. Our purposes are to assess what we have learned from examining trading volume around these announcements and to suggest directions for...

I examine the possibility of information-based trading in a multiperiod consumption setting. I develop a necessary and sufficient condition for trade to occur. Intertemporal substitution introduces a desire to correlate current consumption with future aggregate shocks. When agents have...

We derive equilibrium asset prices when fund managers deviate from benchmark indices to exploit noise-trader induced distortions but fund investors constrain these deviations. Because constraints force managers to buy assets that they underweight when these assets appreciate, overvalued assets...

The peer-to-peer loan market was designed to bring together borrowers and lenders without banks as middlemen. Yet over time P2P lending platforms have evolved into new intermediaries, performing essentially all tasks related to loan evaluation. By contrast, lenders are overwhelmingly passive and...

Long-held intuition dictates that information-based trade is impossible without exogenous noise. Risk seekers can resolve this conundrum. Even though such agents have negative risk aversion, they act as utility maximizers because they fully internalize their impact on prices. If their love of...

In this paper, we attempt to assess the potential importance of different types of traders (i.e., those with public and private information) in financial markets using a specification of the standardized duration. This approach allows us to test unobserved heterogeneity in a nonlinear version...

We propose a tractable equilibrium model to examine how margin requirements affectasset prices, market volatility, and market participants' welfare. Weshow that margin requirements can have opposite effects on market volatility whenthey constrain different investors and thus can help explain why...
