This paper develops a general continuous-time evolutionary finance model with time-dependent strategies. It is shown that the continuous model, which is a limit of a general discrete model, is well-defined and if there exists one completely diversified strategy in the market, then there is no...

law of one price, and is present in all but risk-neutral economies. We test the cross-sectional predictions of our theory … equity than for assets, and stronger for more levered firms — consistent with the theory. We test also the timeseries … implications of the theory. Time variation in asset ivol causes time variation in the option value of equity that translates into …

In dealership markets, asymmetric information feeds through to higher transaction costs as dealers adjust their bid-ask spreads to compensate for anticipated losses. In this paper, we show that the presence of asymmetric information can also provide a positive externality to those market...

Empirical measures of world consumption growth risk have failed to rationalize the cross-section of country equity returns. We propose a new factor, termed "the global consumption factor", to explain the patterns in risk premiums on international equity markets. We identify this factor as the...

This paper examines real-time applications of quickest disorder detection techniques for timing stock markets. The focus is on the stochastic disorder model by Shiryaev, Zhitlukhin, and Ziemba (2014, 2015), Zhitlukhin and Ziemba (2016) and their optimal stopping rule. The model uses sequential...

Many monetary studies on the portfolio balance effect omit its impact to equity returns. Motivated through a simple general equilibrium model, we study how changes in the bond supply affect the overall equity market. Our model predicts that exogenous increases (decreases) in the bond supply...

This paper proposes a dynamic information diffusion model that explains the lead-lag reaction of stock prices resulting from the interaction of price trends and implied price risk (IPR). Consistent with our model's predictions, we construct a zero investment underreaction portfolio (overreaction...

I propose a simple time-series risk measure in trading stock market anomalies, CoAnomaly, the time-varying average pairwise correlation among 34 anomalies, which helps to explain both the time-series and the cross-sectional anomaly return patterns. Since correlations among underlying assets...
