We study dual job incentives with a focus on public-service physicians referring patients to their private practices. We call this moonlighting. Not all physicians moonlight; we introduce a group of dedicated doctors who in the base models behave sincerely in the public system. Allowing...

Lipman [2003] shows that in a finite model, the common prior assumption has weak implications for finite orders of beliefs about beliefs. In particular, the only such implications are those stemming from the weaker assumption of a common support. To explore the role of the finite model...

We model physicians as health care professionals who care about their services and monetary rewards. These preferences are heterogeneous. Different physicians trade off the monetary and service motives differently, and therefore respond differently to incentive schemes. Our model is set up for...

The volatility of the price-dividend ratio on stocks, the predictability of stock returns, and the lack of predictability in dividend growth are commonly interpreted as evidence of substantial time-variation in risk premia. We construct the wealth-consumption ratio for the U.S., the...

The literature on self-control problems has typically put forth models that imply behavior that is consistent with the Weak Axiom of Revealed Prefer- ence. Thus, while choice is hypothesized to be the outcome of some under- lying internal con.ict, the resulting choices are perfectly consistent...

Investors earn positive excess returns on high interest rate foreign discount bonds, because these currencies appreciate on average. Lustig and Verdelhan (2005) show that investing in high interest rate foreign discount bonds exposes them to more aggregate consumption risk, while low interest...

This paper exploits a unique data set on the payment card industry to study issues associated with network effects and two-sided markets. We show that consumers concentrate their spending on a single payment network (single-homing), although many maintain unused cards that allow the ability to...

We model asymmetric information arising from physician agency, and its effect on the design of payment and healthcare quantity. The physician-patient coalition aims to maximize a combination of physician profit and patient benefit. The degree of substitution between profit and patient benefit in...

The literature on self-control problems has typically concentrated on immediate temptations. This paper studies a Gul and Pesendorfer [13, 14] style model in which decision-makers are affected by temptations that lie in the future. While temptation is commonly understood to give rise to a demand...
