, 2013 The paper is to study the asymptotic dynamics in nonmonotone comparable almost periodic reaction-diffusion system with Dirichlet boundary condition, which is comparable with uniformly stable strongly order-preserving system. By appealing to the theory of

Vertical mergers without foreclosure
Journal of Economics &Management Strategy, Volume 34, Issue 2, Page 593-611, Summer 2025.Abstract The typical concern about vertical mergers is the foreclosure of downstream rivals. In a vertically related industry where downstream firms have a common supplier, margins can reveal whether upstream competition constrains that supplier.

Penalty methods for a class of non-Lipschitz optimization problems
, 2016 We consider a class of constrained optimization problems with a possibly nonconvex non-Lipschitz objective and a convex feasible set being the intersection of a polyhedron and a possibly degenerate ellipsoid.

Adoption epidemics and viral marketing
Theoretical Economics, Volume 20, Issue 2, Page 453-480, May 2025.An innovation (e.g., new product or idea) spreads like a virus, transmitted by those who have previously adopted it. Agents update their beliefs about innovation quality based on private signals and when they hear about the innovation. We characterize equilibrium adoption dynamics and the resulting lifecycle of virally‐spread innovations.

PhasePack: A Phase Retrieval Library
, 2017 Phase retrieval deals with the estimation of complex-valued signals solely from the magnitudes of linear measurements. While there has been a recent explosion in the development of phase retrieval algorithms, the lack of a common interface has made it ...

An analytical model of search and bargaining with divisible money
Theoretical Economics, Volume 20, Issue 2, Page 713-761, May 2025.We propose a standard search and bargaining model with divisible money, in which only the random matching market opens and the generalized Nash bargaining settles each trade. Assuming fixed production costs, we analytically characterize a tractable equilibrium, called a pay‐all equilibrium, and prove its existence. Each buyer pays all the money holding

Nonmonotonic Aging and Memory Retention in Disordered Mechanical Systems
Physical Review Letters, 2017 We observe non-monotonic aging and memory effects, two hallmarks of glassy dynamics, in two disordered mechanical systems: crumpled thin sheets and elastic foams. Under fixed compression, both systems exhibit monotonic non-exponential relaxation. However, when after a certain waiting time the compression is partially reduced, both systems exhibit a non-

Econometrica, Volume 93, Issue 2, Page 623-659, March 2025.Is more novel research always desirable? We develop a model in which knowledge shapes society's policies and guides the search for discoveries. Researchers select a question and how intensely to study it. The novelty of a question determines both the value and difficulty of discovering its answer.

Multiprocess parallel antithetic coupling for backward and forward Markov Chain Monte Carlo
, 2005 Antithetic coupling is a general stratification strategy for reducing Monte Carlo variance without increasing the simulation size. The use of the antithetic principle in the Monte Carlo literature typically employs two strata via antithetic quantile ...
