We present a continuous-time contracting model under moral hazard with many agents. The principal contracts many agents as a team, and they jointly produce correlated outcomes. We show the optimal contract for each agent is linear in outcomes of all other agents as well as his/her own. The...

We present a market microstructure model to examine specialist's strategic participation decisions in a security market where there are noise traders, limit order traders, an insider and a specialist. We argue that the specialist's participation rate depends on the depth of the limit book and...

We exposit an integrated agency model of multi-period career concerns and labor market equilibrium with managerial reservation utility levels, and thus pay levels, determined endogenously for firms of different sizes. Stochastic managerial talent takes two forms: a manager drawn from a tighter...

We exposit an integrated agency model of multi-period career concerns and labor market equilibrium with managerial reservation utility levels, and thus pay levels, determined endogenously for firms of different sizes. Based on observations from a long time-series of S&P 1500 companies, we...

We present a simple discrete-time version of the continuous-time agency model under mean-volatility joint ambiguity uncertainties, which conveniently captures a number of important properties of optimal contracts without having to rely on complex continuous-time mathematical issues. The...

We present a continuous-time agency model under mean-volatility joint ambiguity uncertainties, where both the principal and agent exhibit Gilboa-Schmeidler's extreme ambiguity aversion. For this, we extend the martingale method well known in the agency literature, by allowing not only the mean...

We present an integrated agency model of career concerns and labor market equilibrium. Unlike the existing literature, our managerial reservation utility levels and thus their pay levels are endogenously determined, and managers with high expected talent levels are not necessarily hired by large...

We present a jump-diffusion international asset pricing model with stochastic exchange rates and inflation rates when investors consume both traded and nontraded goods. We argue that in general, the Adler-Dumas inflation rate differential may not fully capture PPP deviation risks, unless all...

In spite of the importance of optimal contracting problems under moral hazard and adverse selection, current literature offers no optimal solutions to contracting problems under moral hazard and adverse selection with risk averse agents. The agent's risk aversion, however, appears to be critical...
