Proportional dynamics in exchange economies
We study the proportional dynamics in exchange economies, where each player starts with
some amount of money and a good. Every day, players bring one unit of their good and …

Ascending-price algorithms for unknown markets
We design a simple ascending-price algorithm to compute a (1+ ε)-approximate equilibrium
in Arrow-Debreu markets with weak gross substitute property. It applies to an unknown …

An auction algorithm for market equilibrium with weak gross substitute demands
We consider the Arrow–Debreu exchange market model under the assumption that the
agents' demands satisfy the weak gross substitutes (WGS) property. We present a simple …

Exchange markets: proportional response dynamics and beyond
S Brânzei - ACM SIGecom Exchanges, 2021 - dl.acm.org
The exchange market is a basic model of an economy, where agents bring resources that
they own to the market in order to exchange them for other goods that they need. There is a …

On Stability and Learning of Competitive Equilibrium in Generalized Fisher Market Models: A Variational Inequality Approach
M Datar - arxiv preprint arxiv:2501.07265, 2025 - arxiv.org
In this work, we study a generalized Fisher market model that incorporates social influence.
In this extended model, a buyer's utility depends not only on their own resource allocation …

Markets for public decision-making
A public decision-making problem consists of a set of issues, each with multiple possible
alternatives, and a set of competing agents, each with a preferred alternative for each issue …

Budgetary effects on pricing equilibrium in online markets
Following the work of Babaioff et al, we consider the pricing game with strategic vendors and
a single buyer, modeling a scenario in which multiple competing vendors have very good …

S-convexity and gross substitutability
We propose a new concept of S-convex functions (and its variant, semistrictly quasi-S-
(SSQS)-convex functions) to study substitute structures in economics and operations models …
