The aim of this paper is to study the association between weather shocks (droughts and floods) and agricultural market performance in Mozambique. To do so, we employ a dyadic regression analysis on monthly maize prices, transport costs, and spatial identification of markets as well as droughts and flooded areas. Our estimates show that, while a drought reduces price differences between markets, price dispersion increases during flood periods, an effect that is mainly driven by increases in

An important implication of our results is that markets show some degree of efficiency during supply shock periods in Mozambique. However, spatial market integration continues to be insufficient, probably due to high transfer costs.
