This paper documents the evolution of markups and concentration, detects causality between firm churning and markups/concentration, and determines the impact of fixed costs on markups.
Fertilizer use remains below recommended rates in most of Sub-Saharan Africa, contributing to low crop yields and poverty. Michelson et al. (2021) explore the role of fertilizer quality.
Bargaining over purchase prices with microenterprise owners in Ghana, Hardy et al. (2020) show that poorer sellers agree to significantly lower prices than wealthier peers.
This research note describes experimental evidence from Kenya on intermediary market structure. We find that traders act consistently with joint profit maximization.
The primary goal of this paper is to efficiently recover consistent markups from firm-level production technology under cost minimization settings in order to document the relationship between unobserved idiosyncratic productivity shocks and endogenous markups.
This project will analyse how increased competition affects prices, quality, and firm entry and exit at the market level through a randomised rollout of new stores by an NGO with a reputation for high quality.
This project uses an RCT to study two interventions that may address market frictions caused by information asymmetry in the context of markets for maize and bean seeds.
