Recent studies have raised concerns on the inevitability of chaos in congestion games with
large learning rates. We further investigate this phenomenon by exploring the learning …

Abstract The Dixit-Stiglitz model of monopolistic competition with symmetric CES demand
system with gross substitutes is widely used as a building block across many applied …

To understand theoretically how competitive pressures affect selection and sorting of firms
with different productivity, we study the Melitz (2003) model under the HSA (Homothetic with …

Main Results: In each of these 3 classes,• The substitutability is increasing in 𝑉, if and only if
Marshall's 2nd law of demand holds.• Increasing (decreasing) substitutability implies …

We propose and characterize parametric families of homothetic demand systems, which
feature a constant pass-through rate that is common across otherwise heterogenous …

We study the dynamics of simple congestion games with two resources where a continuum
of agents behaves according to a version of Experience-Weighted Attraction (EWA) …
