摘要：This paper studies an optimal procurement mechanism for a newsvendor-like problem where the buyer's (newsvendor's) purchase price of the supplies is not fixed, but determined through interaction with candidate suppliers. The buyer has priors on the suppliers' costs but does not know their costs exactly. Recent literature has shown how the buyer can implement the optimal procurement mechanism by announcing a revenue function (specifying a payment for each quantity the buyer may purchase), then ...

摘要：In today's multibrand, multichannel marketplace, optimal channel design involves issues such as distribution intensity, channel exclusivity, vertical and horizontal coordination, and online offline mixed structures. We investigate how a firm's choice in these design issues affects its profitability under varying levels of brand and outlet differentiation. Our spatial model explicitly captures heterogeneous consumer preference for brand position, store location, and outlet type, under various c...

摘要：We exploit changes in wind speeds at surfing locations in Switzerland as a source of variation in users' propensity to post content about their surfing activity on an online social network. We exploit this variation to test whether users' online content-generation activity is codetermined with their social ties. Economically significant effects of this type can produce positive feedback that generates local network effects in content generation. When quantitatively significant, the increased c...

摘要：This paper formally analyzes the biases related to self-reporting in hedge fund databases by matching the quarterly equity holdings of a complete list of 13F-filing hedge fund companies to the union of five major commercial databases of self-reporting hedge funds between 1980 and 2008. We find that funds initiate self-reporting after positive abnormal returns that do not persist into the reporting period. Termination of self-reporting, is followed by both return deterioration and outflows from...

摘要：We study the problem faced by a supplier deciding how to dynamically allocate limited capacity among a portfolio of customers who remember the fill rates provided to them in the past. A customer's order quantity is positively correlated with past fill rates. Customers differ from one another in their contribution margins, their sensitivities to the past, and in their demand volatilities. By analyzing and comparing policies that ignore goodwill with ones that account for it, we investigate when...

摘要：When designing contests to motivate employees, should managers organize employees to compete in teams or as individuals? We develop a behavioral economics model that shows that if contestants are averse to being responsible for the team's loss, a team-based (TB) contest can yield higher effort than an individual-based (IB) contest. This prediction is contrary to those of standard economics models, which favor IB contests over TB contests. We test the competing predictions using laboratory econ...

摘要：This paper develops analytical results and insights for the mixed bundling problem of pricing a product line consisting of two component goods (with valuations distributed uniformly and independently in [0, a(1)] and [0, a(2)], respectively, with a(1) < a(2)) and a bundle of the two goods. This setting has previously been considered analytically intractable. By deriving component good prices as exact algebraic functions of the optimal bundle price, I reduce the multiproduct pricing problem to ...

摘要：We study the cross-sectional breadth-return relation by assuming that investors subject to market sentiment hold a biased belief in the aggregate. With a dynamic multiasset model, we predict that the breadth-return relationship can be either positive or negative depending on the relative strength of two offsetting forces-disagreement and sentiment. We find evidence consistent with our predictions. The breadth-return relationship is positive when the sentiment effect is small. However, the rela...

摘要：Utility-maximizing consumption and investment strategies in closed form are unknown for realistic settings involving portfolio constraints, incomplete markets, and potentially a high number of state variables. Standard numerical methods are hard to implement in such cases. We propose a numerical procedure that combines the abstract idea of artificial, unconstrained complete markets, well-known closed-form solutions in affine or quadratic return models, straightforward Monte Carlo simulation, a...

摘要：Heterogeneity in beliefs and time preferences among investors make stock volatility stochastic, even though the volatility of the underlying dividend is constant. Prices of the European options written on this stock admit closed-form solutions, hence their hedging deltas. The Black-Scholes implied volatility surface, which depends on wealth distribution, investors' beliefs, and time preferences, exhibits observed patterns that are widely documented in various options markets. Along with benchm...
