This paper studies optimal relational contracts when the value of the relationship between contracting parties is not commonly known. I consider a principal-agent setting where the principal has persistent private information about her outside option. I show that if the principal has the...

While the comparative statics of asset demand have been studied extensively, surprisingly little work has been done on the behavior of equilibrium asset prices and returns in response to changes in the supplies of securities. This is despite considerable interest in the equity premium and...

Customer switching costs are an important factor in account-based services such as telecommunications, financial, insurance and brokerage services. In these businesses, existing customers incur significant costs if they switch to another provider. Such costs include physical configuration and...

Traditional monopoly pricing models assume that firms have full information about the market demand and consumer preferences. In this paper we study a prototypical monopoly pricing problem for a seller with limited market information and different levels of demand learning capability under...

We study an aggregated marketplace where potential buyers arrive and submit requests-for-quotes (RFQs). There are n independent suppliers modelled as M=GI=1 queues that compete for these requests. Each supplier submits a bid that comprises of a fixed price and a dynamic target leadtime, and the...

A principal-components analysis demonstrates that common earnings factors explain a substantial portion of rm-level earnings variation, implying earnings shocks have substantial systematic components and are not almost fully diversifiable as prior literature has concluded. Furthermore, the...

We develop a two sector general equilibrium model with capital accumulation and convex adjustment costs. We use the model to study capital asset pricing and reallocation, as well as optimal consumption and investment decisions. With two sectors, the consumer balances diversification against the...

A central tenet of organizational justice theory is that people prefer decisions to be made with higher than with lower procedural fairness. The results of five studies unearthed a boundary condition for this general tendency. People who experienced non-contingent success had less of a desire to...

We consider dynamic oligopoly models in the spirit of Ericson and Pakes (1995). We introduce a new computationally tractable model for industries with a few dominant firms and many fringe firms, in which firms keep track of the detailed state of dominant firms and of few moments of the...

Mean-variance investing is all about diversification. Diversification considers assets holistically and exploits the interaction of assets with each other, rather than viewing assets in isolation. Holding a diversified portfolio allows investors to increase expected returns while reducing risks....
