Our approach does not impose a model on the distribution of the customers valuations and only assumes, instead, that purchase choices satisfy incentive-compatible constraints.

We use the intra-personal equilibrium approach to study the problem. Interestingly, we find that the only viable outcome is from the median maximization, b

We formulate the model as a singular stochastic control problem from a social planner’s angleand show that the resulting optimal strategy must be an equilibrium strategy. We prove that the value function associated with the singular stochastic control proble

The positive effect of the credit risk premium (CRP) factor on expected returns is pervasive, stronger for lower-rated bonds and robust to controlling for conventional risk factors and bond characteristics. Besides the systematic CRP factor, idiosy

Speed and information technology advantages allow endogenous liquidity providers (ELPs) to switch between limit and market orders after observing private information. This significantly influences the adverse selection faced by designated market makers (DMMs), thereby generating a gap between liquidity s

The model characterizes the central importance of liquidity management in corporate decision making in the presence of external financing costs. Mathematically, to solve for the recursive equilibrium of the problem, we formulate it as a double-obstacle

There is a correlation ambiguity premium in excess return, which arises from ambiguity-induced changes in market portfolio composition and asset risk exposure. Correlation ambiguity premium can be traced back to under-diversification in favor of high Sharpe ratio assets, which results in less e
