摘要：We experimentally study first-price split-award auction formats as they can be found in procurement markets where suppliers have economies of scale. Our analysis includes sequential and combinatorial auctions, which allow for bids on the package of two shares and single shares. We derive equilibrium predictions as hypotheses for bidder behavior in our laboratory experiments. These equilibrium predictions help explain important patterns in our experimental results. The combinatorial first-price...

摘要：Contemporary products are usually designed and produced in large inter-firm supply networks rather than by single firms. However, our understanding of such networks is still limited due to the lack of network-wide empirical data as well as the complexity and nonlinearity of supply networks. Herein, we introduce a network formation model to extend and generalize the prior empirical studies that have revealed variable hierarchy topologies and firm-level transaction specificities across the suppl...

摘要：Recovery of resources from waste streams present important opportunities in mitigating environmental and energy challenges in many countries. In this paper, we develop an optimization-based approach to study the robustness of resource recovery systems in achieving economic feasibility under feedstock uncertainty. Two key characteristics of the feedstock that influence recovery performance are its volume and composition. We propose models of feedstock robustness functions to perform robustness ...

摘要：It is well-known that adding a little flexibility to the right place is an effective strategy to improve the performance of operations in the face of demand uncertainties, to ensure high level of capacity utilization. However, given that system disruptions are ubiquitous, the legacy flexibility designs may perform poorly under disruptions to supply or capacity installations. In this study, we focus on the design of reliable and sparse flexibility structures that consistently meet a reasonable ...
