Effective Choice and Boundedness Principles in Computable Analysis
, 2009 In this paper we study a new approach to classify mathematical theorems according to their computational content. Basically, we are asking the question which theorems can be continuously or computably transferred into each other?

Theoretical Economics, Volume 21, Issue 1, Page 71-98, January 2026.In the classical Bayesian persuasion model, an informed player and an uninformed one engage in a static interaction. This work extends this classical model to a dynamic setting where the state of nature evolves according to a Markovian law, allowing for a more realistic representation of real‐world situations where the state of nature evolves over time.

An Elementary Proof of The 2-Dimensional Version of The Brouwer Fixed Point Theorem [PDF]
, 2014 We give an elementary proof of the 2-dimensional version of the Brouwer fixed point theorem. The proof can be extended to the n-dimensional version naturally.

Coordination with sequential information acquisition
Theoretical Economics, Volume 21, Issue 1, Page 132-166, January 2026.We investigate how differences in initial beliefs and sequential information choices affect the likelihood of coordination failure. To do so, we embed interim information acquisition (i.e., information acquisition after observing initial private information) into a standard global game mode with a normal information structure and improper prior.

A New Conservative Difference Scheme for the General Rosenau-RLW Equation
Boundary Value Problems, 2010 A new conservative finite difference scheme is presented for an initial-boundary value problem of the general Rosenau-RLW equation. Existence of its difference solutions are proved by Brouwer fixed point theorem.

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.

Cost‐Effectiveness Analysis of Risky Health Interventions: Moving Beyond Risk Neutrality
Ratio, Volume 38, Issue 4, Page 219-227, December 2025.ABSTRACT Cost‐effectiveness analysis for health interventions is traditionally conducted in a risk‐neutral way, insensitive to risk attitudes in the population, which are potentially non‐neutral. While the standard outcome metric of quality‐adjusted life years (QALYs) aims to be deferential to people's valuations of health states, cost‐effectiveness ...

Constant Rank Bimatrix Games are PPAD-hard
, 2014 The rank of a bimatrix game (A,B) is defined as rank(A+B). Computing a Nash equilibrium (NE) of a rank-$0$, i.e., zero-sum game is equivalent to linear programming (von Neumann'28, Dantzig'51). In 2005, Kannan and Theobald gave an FPTAS for constant rank

Existence of a non‐stationary equilibrium in search‐and‐matching models: TU and NTU
Theoretical Economics, Volume 20, Issue 4, Page 1411-1460, November 2025.This paper proves the existence of a non‐stationary equilibrium in the canonical search‐and‐matching model with heterogeneous agents. Non‐stationarity entails that the number and characteristics of unmatched agents evolve endogenously over time.

Results in Nonlinear Analysis, 2019 Our title means that the Knaster-Kuratowski Mazurkiewicz theorem in 1929 implies the Hahn-Banach theorem. This theorem originated from Hahn in 1926 and Banach in 1929 is of basic importance in the analysis of problems concerning the existence of ...
