摘要：In live broadcasting, the break lengths available for commercials are not always fixed and known in advance (e.g., strategic and injury time-outs are of variable duration in live sports transmissions). Broadcasters actively manage their advertising revenue by jointly optimizing sales and scheduling policies. We characterize the optimal dynamic schedule in a simplified setting that incorporates stochastic break durations and advertisement lengths of 15 and 30 seconds. The optimal policy is a gr...

摘要：Social scientists have long considered what mechanisms underlie repeated exchange. Three mechanisms have garnered the majority of this attention: formal contracts, relational contracts, and relationally embedded social ties. Although each mechanism has its virtues, all three exhibit a common limitation: an inability to fully explain the continuation and stability of intertemporal exchange between individuals and organizations in the face of change. Drawing on extensive quantitative data on app...

摘要：Extended producer responsibility (EPR) is a policy tool that holds producers financially responsible for the post-use collection, recycling, and disposal of their products. Many EPR implementations are collective-a large collection and recycling network (CRN) handles multiple producers' products in order to benefit from scale and scope economies. The total cost is then allocated to producers based on metrics such as their return shares by weight. Such weight-based proportional allocation mecha...

摘要：We study the allocation of heterogeneous services to agents with incomplete information and without monetary transfers. Agents have private, multidimensional utilities over services, drawn from commonly known priors. The social planner's goal is to maximize a potentially complex public objective. For tractability, we take an engineering approach, in which we solve a large-market approximation, and convert the solution into a feasible finite-market mechanism that still yields good results. We a...

摘要：The long-run abnormal returns following both stock repurchases and seasoned equity offerings disappear for the events in 2003-2012. The disappearance is associated with the changing market environment: increased institutional investment, decreased trading costs, improved liquidity, and enhanced regulations on corporate governance and information disclosure. In response to the more efficient pricing of stocks, firms become less opportunistic in stock repurchases and offerings. Recent events of ...

摘要：This study considers a basic inventory management problem with nonzero fixed order costs under interval demand uncertainty. The existing robust formulations obtained by applying well-known robust optimization methodologies become computationally intractable for large problem instances due to the presence of binary variables. This study resolves this intractability issue by proposing a new robust formulation that is shown to be solvable in polynomial time when the initial inventory is zero or n...
