Journal of Management Studies, EarlyView.Abstract While research on ecosystems and their orchestration has grown rapidly, we still know little about how individual strategic leaders may mobilize ecosystemic action in times of disruption. This article addresses this gap by drawing on an in‐depth case study of the Antwerp Square Mile, the world’s oldest and most renowned diamond trading ...

Incentive alignment in ecosystems: The role of complementarity types and multi‐sided bargaining
Strategic Management Journal, Volume 47, Issue 1, Page 228-256, January 2026.Abstract Research Summary Alignment of incentives to improve value creation in ecosystems is crucial to their growth and survival. We examine how two fundamental ecosystem features affect alignment: types of complementarities and their interplay with multi‐sided bargaining over value.

Tarski's Theorem, Supermodular Games, and the Complexity of Equilibria [PDF]
, 2019 The use of monotonicity and Tarski's theorem in existence proofs of equilibria is very widespread in economics, while Tarski's theorem is also often used for similar purposes in the context of verification. However, there has been relatively little in the way of analysis of the complexity of finding the fixed points and equilibria guaranteed by this ...

Equilibrium Existence in First‐Price Auctions With Private Values
Econometrica, Volume 94, Issue 1, Page 193-224, January 2026.We provide sufficient conditions for equilibrium existence in first‐price auctions with private values that accommodate non quasi‐linear utilities and value‐distributions that contain atoms and exhibit positive or negative correlation. These conditions show that equilibrium existence often turns on properties of a single statistic of the joint ...

The cone of supermodular games on finite distributive lattices [PDF]
Discrete Applied Mathematics, 2019 In this article we study supermodular functions on finite distributive lattices. Relaxing the assumption that the domain is a powerset of a finite set, we focus on geometrical properties of the polyhedral cone of such functions. Specifically, we generalize the criterion for extremality and study the face lattice of the supermodular cone.

Data and Competition: A Simple Framework
The RAND Journal of Economics, Volume 56, Issue 4, Page 494-510, Winter 2025.ABSTRACT Does enhanced access to data foster or hinder competition among firms? Using a competition‐in‐utility framework that encompasses many situations where firms use data, we model data as a revenue‐shifter and identify two opposite effects: a mark‐up effect according to which data induces firms to compete harder, and a surplus‐extraction effect ...

Multivariate Incomplete Information in the Mixture Model of Contests
The RAND Journal of Economics, Volume 56, Issue 4, Page 607-624, Winter 2025.ABSTRACT A general mixture model of contests is introduced, combining stochastic performance and multivariate incomplete information. Performance is determined by a mixture distribution with endogenous weights on a good and bad distribution, respectively.

Econometrica, Volume 93, Issue 6, Page 2007-2042, November 2025.We study reputation formation where a long‐run player repeatedly observes private signals and takes actions. Short‐run players observe the long‐run player's past actions but not her past signals. The long‐run player can thus develop a reputation for playing a distribution over actions, but not necessarily for playing a particular mapping from signals ...

Existence and Structure of Nash Equilibria for Supermodular Games
Order, 2022 Two theorems announced by Topkis about the topological description of sublattices are proved. They are applied to extend some classical results concerning the existence and the order structure of Nash equilibria of certain supermodular games, with some problems in Zhou's proof corrected.
