摘要：In this paper, we present formulas for the valuation of debt and equity of firms in a financial network under comonotonic endowments. We demonstrate that the comonotonic setting provides a lower bound and Jensen???s inequality provides an upper bound to the price of debt under Eisenberg-Noe financial networks with bankruptcy costs. Such financial networks encode the interconnection of firms through debt claims. The proposed pricing formulas consider the realized, endogenous recovery rate on de...

摘要：We revisit the stochastic inventory game in which n players compete by setting their individual inventory levels in a market with stockout-based demand substitution. Because of specific tractability issues, the prior literature has largely focused on versions of this competitive newsvendor problem with assumptions on the number of players and their substitution behavior. In this note, we develop an approach to solve instances of this problem with any number of players and multistage spillovers...

摘要：Policymakers often seek to integrate markets as a way to maximize social welfare. Prior research has examined the effect of market integration on social welfare (surplus) only at two extremes-when the markets are fully integrated and when they are fully isolated. But there is scarce information available for (i) how large the social surplus is at intermediate levels of market integration and (ii) whether social surplus is maximized when markets are fully integrated, fully isolated, or partiall...

摘要：A deadlock occurs when two or more trains are preventing each other from moving forward by occupying the required tracks. Deadlocks are rare but pernicious events in railroad operations and, in most cases, are caused by human errors. Recovering is a time-consuming and costly operation, producing large delays and often requiring crew rescheduling and complex switching moves. In practice, most deadlocks involve only two long trains missing their last potential meet location. In this paper, we pr...

摘要：In most Australian cities, container ports are located close to the city, with transportation to and from the port facilitated by trucks. Recently, with a view to reducing container-truck induced city congestion and pollution, state and federal governments have begun championing a modal switch to short-haul rail for these transportation tasks. In this paper, we describe a metropolitan container transportation problem arising from this context that seeks to effectively leverage both modes of tr...

摘要：We consider a stochastic inventory control problem under censored demand, lost sales, and positive lead times. This is a fundamental problem in inventory management, with significant literature establishing near optimality of a simple class of policies called base-stock policies as well as the convexity of long-run average cost under those policies. We consider a relatively less studied problem of designing a learning algorithm for this problem when the underlying demand distribution is unknow...

摘要：We consider a matching market where buyers and sellers arrive according to independent Poisson processes at the same rate and independently abandon the market if not matched after an exponential amount of time with the same mean. In this centralized market, the utility for the system manager from matching any buyer and any seller is a general random variable. We consider a sequence of systems indexed by n where the arrivals in the nth system are sped up by a factor of n. We analyze two familie...

摘要：A buyer seeking to outsource production may be able to find ways to reduce a potential supplier's cost, for example, by suggesting improvements to the supplier's proposed production methods. We study how a buyer could use such cost-reduction investigations by proposing a three-step supplier selection mechanism: First, each of several potential suppliers submits a price bid for a contract. Second, for each potential supplier, the buyer can exert an effort to see if the buyer can identify how th...

摘要：We consider a setting where agents in a social network take binary actions that exhibit local strategic complementarities. Their payoffs are affine and increasing in an underlying real-valued state of the world. An information designer commits to a signaling mechanism that publicly reveals a signal that is potentially informative about the state. She wants to maximize the expected number of agents who take action 1. We study the structure and design of optimal public signaling mechanisms. The ...

摘要：We study the supply chain implications of dynamic pricing. Specifically, we estimate how reducing menu costs-the operational burden of adjusting prices-would affect supply chain volatility. Fitting a structural econometric model to data from a large Chinese supermarket chain, we estimate that removing menu costs would (i) reduce the mean shipment coefficient of variation by 7.2 percentage points (pp), (ii) reduce the mean sales coefficient of variation by 4.3 pp, and (iii) reduce the mean bull...
