摘要：We analyze financial intermediation chains in a search economy that is populated by investors with heterogeneous valuations of an asset. In equilibrium, investors with moderate valuations choose to be intermediaries, and those with extreme valuations are their customers. The average length of intermediation chains is shown to be decreasing in search cost, search speed, and market size but increasing in investors' trading needs. These predictions are distinct from those implied by existing mode...

摘要：When preferences are sensitive to context, firms may influence purchase decisions by designing the environment of consumption choices. This paper studies how competitive retailers optimally design their product line if preferences at the store depend on whether the choice set draws consumer attention to the quality or price of a product. Before making a purchase decision, a consumer chooses among retailers without (fully) anticipating that her preferences at the store are malleable. We show th...

摘要：Technical debt refers to the design, development, and implementation shortcuts taken by firms when deploying accounting information systems. Prior system-level studies have shown that such shortcuts decrease the reliability of systems and increase the long-term system maintenance obligations. On the one hand, technical debt may cause system disruptions that impair firm-level performance. On the other hand, incurring technical debt may aid firms to expedite their systems deployment and to imple...

摘要：Participatory budgeting enables the allocation of public funds by collecting and aggregating individual preferences. It has already had a sizable real-world impact, but making the most of this new paradigm requires rethinking some of the basics of computational social choice, including the very way in which individuals express their preferences. We attempt to maximize social welfare by using observed votes as proxies for voters' unknown underlying utilities, and analytically compare four prefe...

摘要：Motivated by online advertising, we model and analyze a revenue management problem where a platform interacts with a set of customers over a number of periods. Unlike traditional network revenue management, which treats the interaction between platform and customers as one-shot, we consider stateful customers who can dynamically change their goodwill toward the platform depending on the quality of their past interactions. Customer goodwill further determines the amount of budget that they allo...

摘要：In a crowdsourcing contest, innovation is outsourced by a firm to an open crowd that competes in generating innovative solutions. Given that the projects typically consist of multiple attributes, how should the firm optimally design a crowdsourcing contest for such a project? We consider two alternative mechanisms. One is a joint contest, where the best solution is chosen from the joint solutions across attributes submitted by all contestants. The other ismultiple separate parallel subcontests...

摘要：For discretionary services, longer service duration implies higher service quality. We study the optimal design and pricing of discretionary service lines, a range of services that are vertically differentiated through their duration (quality), offered to a market with customers who are heterogeneous in terms of their sensitivity to service duration. In a resource-constrained environment with stochastic arrival of demand, longer service duration also implies longer wait, which all customers di...

摘要：Using a multitier mapping of supply-chain relationships constructed from granular global, firm-to-firm supplier-customer linkages data, we quantify the degree of financial risk propagation from the supply network beyond firms' direct supply-chain connections and isolate structural network properties serving as significant moderators of risk propagation. We first document a baseline fact: a significant proportion of tier-2 suppliers are shared by tier-1 suppliers. We then construct two simple m...

摘要：Recent years have witnessed the rise of queue scalping in congestion-prone service systems. A queue scalper has no material interest in the primary service but proactively enters the queue in hopes of selling his spot later. This paper develops a queueing-game-theoretic model of queue scalping and generates the following insights. First, we find that queues with either a very small or very large demand volume may be immune to scalping, whereas queues with a nonextreme demand volume may attract...

摘要：We consider a periodic-review single-product inventory system with fixed cost under censored demand. Under full demand distributional information, it is well known that the celebrated (s, S) policy is optimal. In this paper, we assume the firm does not know the demand distribution a priori and makes adaptive inventory ordering decisions in each period based only on the past sales (a.k.a. censored demand). Our performance measure is regret, which is the cost difference between a feasible learni...
