Tangles, Trees of Tangles, and Submodularity [PDF]
, 2021 This thesis treats tangles in abstract separation systems, a way of characterising dense or well-connected substructure or ‘clusters’ in various contexts, and the underlying submodularity properties that one can demand of these separation systems ...

Security Design Under Common‐Value Competition
Econometrica, Volume 94, Issue 5, Page 1717-1759, September 2026.This paper studies security design by bidders with dispersed information about a common‐value investment opportunity. Among a broad set of securities, bidders offer debt financing—the flattest securities. A first reason is that debt mitigates bidders' exposure to the winner's curse when there are two bidders.

Naval Research Logistics (NRL), Volume 73, Issue 5, Page 743-763, August 2026.ABSTRACT This paper examines the impacts of Volume‐Based Procurement (VBP) policies on pharmaceutical supply chains, with a focus on the strategic behaviors of manufacturers. VBP aims to reduce costs and stabilize supplies by centralizing procurement through competition based on volumes and prices.

CoRR, 2023 This paper examines the Balanced Submodular Flow Problem, that is the problem of finding a feasible submodular flow minimizing the difference between the flow values along the edges. A min-max formula is given to the problem and an algorithm is presented to solve it using $O(m^2)$ submodular function minimizations.

Naval Research Logistics (NRL), Volume 73, Issue 5, Page 810-835, August 2026.ABSTRACT We are concerned with the stability of a transferable‐utility cooperative (TU) game. First, the concept of core can be weakened so that the blocking of changes is limited to only those with multilateral backings. This principle of consensual blocking, as well as the traditional core‐defining one of unilateral blocking and one straddling in ...

Submodular participatory budgeting
Theoretical Computer ScienceParticipatory budgeting refers to the practice of allocating public resources by collecting and aggregating individual preferences. Most existing studies in this field often assume an additive utility function, where each individual holds a private utility for each candidate project, and the total utility of a set of funded projects is simply the sum ...

On the Selection of Information Sources for Gossip Spreading
International Journal of Distributed Sensor Networks, 2015 Information diffusion is efficient via gossip or rumor spreading in many of the next generation networks. It is of great importance to select some seed nodes as information sources in a network so as to maximize the gossip spreading.

Optimal Selling Mechanisms With Endogenous Seller Outside Offers
International Economic Review, Volume 67, Issue 3, Page 875-891, August 2026.ABSTRACT We examine a two‐stage selling mechanism design problem, where the buyer makes her report and the seller endogenously decides his effort (hidden investment) to generate a possibly better outside offer. The optimal mechanism shows that the seller's effort depends on the reported value of the buyer; a higher value lowers the seller's incentive ...
