Gains from market integration: Welfare effects of new rural roads in Ethiopia

This paper estimates the welfare gains from the construction of rural roads that connect agricultural villages to market centers. I take theoretical predictions from Ricardian trade models to a rich high spatial resolution micro data on agricultural production from Ethiopia, which coincides with a period of extensive rural road construction. I estimate that the road construction resulted in an approximately 13% increase in real agricultural income, on average, and show that this increase is attributed to the mechanisms suggested in the Ricardian trade model: the prices of villages' comparative advantage crops increased, and villages reallocated land for these crops following decreases in trade costs.
