The practice of selling multiple products or services under nonlinear pricing has a long history in the business community. Consumers may face demand uncertainty when choosing a service plan, and preferences for multiple products or services may be inter-dependent. To examine a demand system...

In this paper, we argue that models coming from a variety of fields share a common structure that we call matching function equilibria. This structure revolves around an aggregate matching function and a system of nonlinear equations. This encompasses search and matching models, matching models...

This paper investigates the identification and parametric estimation of marriagematching models. We first extend the identification result for the empirical dynamicmarriage matching model proposed in Choo (2015) by allowing the unobserved het-erogeneities to be drawn from more general...

Quantile factor models (QFM) represent a new class of factor models for high-dimensional panel data. Unlike approximate factor models (AFM), which only extract mean factors, QFM also allow unobserved factors to shift other relevant parts of the distributions of observables. We propose a quantile...
