Uneven growth in the extensive margin: explaining the lag of agricultural economies

Guzmán Ourens ()

No 1704, CEPREMAP Working Papers (Docweb) from CEPREMAP

Abstract: This paper documents that growth in the extensive margin is on average lower in the agricultural sector than in other activities. We introduce this new fact into a simple model of trade to show its relevance for regions specialized in the lagging sector. Diversity-loving consumers endogenously reduce the share of their expenditure devoted to that sector. The region specialized in it receives a decreasing share of world income, which results in diverging income and welfare trajectories with respect to the rest of the world. Appropriating a decreasing share of world value pushes downward the relative wage of the agricultural re- gion and lowers the price of its exports relative to that of its imports, resulting in terms of trade deterioration. This result, supported by empirical evidence, separates our theoretical results from those obtained in a similar model of un- even output growth between sectors. We present empirical evidence for the main testable results of the model. Our model is the first replicating these facts with- out the need of heterogeneous consumers or products, nor resorting to political or institutional explanations.
