This chapter provides an overview of the recent and growing econometric literature studying
how consumers search for products. We begin with a brief review of theoretical models of …

We propose a model of nonsequential consumer search where consumers and firms differ in
search and production costs respectively. We characterize the equilibrium of the game. We …

We extend the literature on simultaneous search by allowing for differentiated products and
search cost heterogeneity. We show conditions under which a symmetric price equilibrium …

We focus on markets with frictions, such as transaction costs, asymmetric information, search
and matching frictions. We discuss how such frictions affect allocations, favor the emergence …

This paper develops a dynamic model of consumer search that, despite placing very little
structure on the dynamic problem faced by consumers, allows us to exploit intertemporal …

This doctoral dissertation documents price-setting behavior in Brazil using a unique dataset
of store-level price quotes collected by the Fundação Instituto de Pesquisas Econômicas …

This thesis comprises three essays addressing questions related to pricing, competition, and
consumer welfare in imperfectly competitive industries characterised by the existence of …

We propose a non-sequential search model with a continuum of consumers and a finite
number of firms. Both consumers and firms are heterogeneous. Consumers differ in search …

An increase in quality shifts up the distribution of match utilities offered by firms and makes
consumers pickier. The number of products that consumers inspect does not necessarily …

Plano Real put an end to hyperinflation in 1994 and significantly altered price-setting
behavior in Brazil. This paper investigates the impact of Plano Real on search frictions. We …
