摘要：E-commerce platforms struggle to create and maintain high-quality reputation systems. One promising option is purchase verification, which confirms that the user reviewing a product purchased the product from the platform. Previous works comparing platforms that require purchase verification with platforms that do not offer purchase verification found that review manipulation is easier in the latter. But what happens in platforms where purchase verification is optional? In such platforms, ther...

摘要：A renewable energy site can expand its power generation capacity by an endogenous amount but may also want to shut down to save on fixed operating costs and interest payments if the market prospects deteriorate. We model such circumstances and derive managerial implications that help us explain real-world conundrums, illustrating the intricate interactions between the operational decision to build up capacity and the financial decision to exit an industry. Shutting down may be delayed in the h...

摘要：Motivated by the potential growth of capacity markets due to 3-D manufacturing, we examine the integration of long- and short-term contracts for a capacity marketplace. In the marketplace, manufacturers and suppliers first participate in long-term contracts in which manufacturers reserve capacity at one or more suppliers. Subsequently, manufacturers and suppliers trade in a spot market to fulfill residual demand and sell residual capacity, respectively; in the spot market, the equilibrium pric...

Our paper's novelty consists of explicitly acknowledging a distinctive property of many services in that firms incur customer-specific service costs after the contract is signed. Hence, not only the customers' willingness-to-pay and as such demand but also the firms' supply are related to customer characteristics. In ...
