摘要：Many products have similar or common attributes and are thus correlated. We show that, when these attributes are uncertain for consumers, a complementarity effect can arise among competing products in the sense that the lower price of one product may increase the demands for the others. This effect occurs when consumers sequentially search for information about both common and idiosyncratic product attributes before purchase. We characterize the optimal search strategy for the correlated searc...

摘要：We develop a simple theoretical framework for thinking about how geographic frictions, and in particular travel costs, shape scientists' collaboration decisions and the types of projects that are developed locally versus over distance. We then take advantage of a quasi-experiment-the introduction of new routes by a low-cost airline-to test the predictions of the theory. Results show that travel costs constitute an important friction to collaboration: after a low-cost airline enters, the number...

摘要：This paper addresses volunteer labor markets where the lack of price signals, nonpecuniary motivations to supply labor, and limited fungibility of supply lead to market failure. To address the causes of the market failure, we conduct a field experiment with volunteer whole blood donors where we introduce a market-clearing mechanism (henceforth: the Registry). Our intention-to-treat estimates suggest that subjects invited to the Registry, regardless of joining, are 66% more responsive to critic...

摘要：Innovative firms rely increasingly on academic science, yet they exploit only a small fraction of all academic discoveries. Which discoveries in academia do firms build upon? We posit that hubs play the role of bridges between academic science and corporate technology. Tracking citations from patents to approximately 10 million academic articles, we find that hubs facilitate the flow of academic science into corporate inventions in two ways. First, hub-based discoveries in academia are of high...

摘要：I investigate three goals of school choice: welfare, encouraging neighborhood schools, and diversity. I use optimization problems to find the best stable and incentive compatible match for any combination of these objectives. These problems assume there is a continuum of students and school seats, which allows me to describe the incentive compatibility conditions in a tractable form. I prove that the set of stable matchings is generically continuous in the distribution of students and the scho...

摘要：A buying firm might in the future incur costs associated with a supplier's carbon dioxide emissions, safety violations, or other social or environmental impacts. Learning about a supplier's impacts requires costly effort, but it is necessary (and sometimes sufficient) to reduce those impacts. The capital market valuation of a buying firm reflects investors' estimate of future costs associated with a supplier's impacts, as well as any costs that the buying firm incurs in order to learn about an...

摘要：This paper studies how to schedule medical appointments with time-dependent patient no-show behavior and random service times. The problem is motivated by our studies of independent datasets from countries in two continents that unanimously identify a significant time-of-day effect on patient show-up probabilities. We deploy a distributionally robust model, which minimizes the worst-case total expected costs of patient waiting and service provider's idling and overtime, by optimizing the sched...

摘要：We study the feasibility and optimal design of presale crowdfunding contracts where participating consumers pay a premium above the future expected spot price and financially constrained entrepreneurs balance the potential product-market distortions introduced through presale crowdfunding against the cost of traditional external financing. Our analysis shows how such crowdfunding contracts enable the execution of projects that could not be otherwise undertaken and highlights novel interactions...

摘要：This study examines the effect of audit committee connectedness through director networks on financial reporting quality, specifically the misstatement of annual financial statements. Using network analysis, we examine multiple dimensions of connectedness and find that after controlling for operating performance and corporate governance characteristics, firms with well-connected audit committees are less likely to misstate annual financial statements. In addition, our study demonstrates that a...
