The three chapters of this doctoral dissertation estimate the responses of agricultural productivity, production value of agriculture, and crop supply to some external shocks and policies. Using unique panel datasets for Colombia and the United States, this research provides new insights regarding the responsiveness of agriculture to some socioeconomic effects and related market policies. Chapter 1 studies the impact of armed conflicts in rural areas on legal agricultural productivity in Colombia by using a production function that includes violence shocks such as the forced intra-national displacement of the rural population from 1995 to 2017. Chapter 2 investigates the effect of anti-drug strategies implemented under a joint US-Colombia policy on the value of agricultural production of Colombian regions with coca crops. Chapter 3 examines the impact of a policy in the ethanol market on the supply of biomass from corn production at the extensive and intensive margins.
