摘要：Sourcing new products in advance entails significant risks for a buyer. To reduce the possibility of bringing a mediocre item to the market, buyers can build a large supply base and pick the best available products after uncertainties have materialized. Designing such a supply base is a challenging task: the buyer needs to decide how many suppliers to recruit, and how to split them across potential groups, such as product types or geographies. In this study, we propose a framework to design op...

摘要：We study the merits and limitations of technology improvement (TI) initiatives for managing input-price risk. Such initiatives (e.g., energy efficiency projects) typically reduce the consumption of an input commodity and so result in lower production costs, more sustainable operations, and/or an improved competitive position. This study explores whether TI can also serve to hedge risks. Although TI clearly reduces both average cost and risk exposure, some firms may actually benefit from input-...

摘要：Online crowdfunding has emerged as a powerful tool to raise funds for emergency response. Crowdfunding campaigns can use two transparency tools to attract donors: updates and certification. Updates are additional messages that the organizer issues after launching the campaign and are a form of operational transparency when they communicate the campaign's work to donors. Alternatively, certification is a form of conventional transparency that ensures the campaign truly benefits a charitable pur...

摘要：Many industries are characterized by large buyers and suppliers whose decisions are influenced by the strategic interactions among these parties. Here we present an economic model for a monopolistic buyer that needs to procure a critical item from two candidate suppliers competing to win the buyer's account. The buyer's objective is to design a procurement process that minimizes its total cost. We analyze this problem under one static and two dynamic procurement design choices and investigate ...

摘要：We are entering an era of great expectations towards our cities. The vision of smart city has been pursued worldwide to transform urban habitats into superior efficiency, quality, and sustainability. This phenomenon prompts us to ponder what role the scholars in operations management (OM) can assume. In this essay, we express our initial thoughts on expanding OM to the smart-city scope. We review smart-city initiatives of governments, industry, national laboratories and academia. We argue that...

摘要：The diffusion of technological innovations in developing economies has been facilitated by the use of rent-to-own business models, which give flexibility to customers by allowing them to make incremental payments over time. Understanding the implications of this flexibility is a fundamental problem for an increasing number of firms operating in these markets. In this study, we empirically analyze how consumer usage and payment behaviors interact in an application of rent-to-own to the distribu...

摘要：This paper studies the effects of bank credit availability, trade credit and the capital cost on inventory decisions. There are two competing theories on the effect of bank credit lines on investments. While one (Lins et al. 2010) suggests that the primary role played by undrawn credit is to finance new opportunities, the other (Acharya et al. 2014) suggests that undrawn credit serves primarily as a bank monitored liquidity insurance. We attempt to resolve these two conflict views in the conte...

摘要：In this study, we provide an alternative approach for proving the preservation of concavity together with submodularity, and apply it to finite-horizon non-stationary joint inventory-pricing models with general demands. The approach characterizes the optimal price as a function of the inventory level. Further, it employs the Cauchy-Schwarz and arithmetic-geometric mean inequalities to establish a relation between the one-period profit and the profit-to-go function in a dynamic programming sett...

摘要：Framework agreements (FAs) are commonly used by relief organizations to cooperate with suppliers to pre-position relief items. Many Chinese local authorities with disaster responding experience choose a specific type of FA, the fixed framework agreement (FFA), which contains fixed terms for item quality, quantity, price, and delivery lead time. These FFAs, however, do not fully motivate suppliers to further improve the effectiveness of a humanitarian logistics (HL) operation. We suggest using ...

摘要：We study peer effects on individuals' contributions to a major form of word of mouth-online reviews. Provided by either consumers or third-party professionals, online reviews influence consumer purchasing decisions and hence sales. Individuals have conflicting incentives of free riding and contributing to social capital when writing reviews. We leverage a natural experiment, which led to an exogenous expansion in the user population of a major online review platform, to better understand the t...
