Abstract: We develop a theory of monotone comparative statics based on weak set order, or in short weak monotone comparative statics, and identify the enabling conditions in the context of individual choices, Pareto optimal choices for a coalition of agents, and Nash equilibria of games. Compared with the existing theory based on strong set order, the conditions for weak monotone comparative statics are weaker, sometimes considerably, in terms of the structure of the choice environment and underlying preferences of agents. We apply the theory to establish existence and monotone comparative statics of Nash equilibria in games with strategic complementarities and of stable many-to-one matchings in two-sided matching problems, allowing for general preferences that accommodate indifferences and incomplete preferences.

Abstract:

Colombia is the world’s major producer of coca leaves used for the production of cocaine. An important pillar of Colombia’s efforts to curb the production of this illicit crop is to induce farmers to substitute coca

for a viable legal alternative. In this paper we identify the extent to which farmers respond to variation in the price of five of the most promising legal alternatives when deciding how much coca to plant – coffee,

sugar, palm oil, cocoa, and banana. We do this using a rich, spatially very detailed dataset that contains yearly information on the amount of coca grown in each of over 31,000 villages (veredas) in Colombia over the

period 2001-2018. To identify our main effect of interest, we exploit exogenous variation in the prices of the five alternative legal export crops that we consider, in combination with detailed information about the soil

and climatic suitability of each village for growing these legal alternatives, as well as for growing coca. We find that farmers in villages more suitable for growing coffee, palm oil and banana differentially respond to price

increases of these particular legal alternatives by planting less coca. We discuss why we find this effect for these three crops only, and not for cocoa or sugar. Moreover, we provide evidence that these effects are confined

to villages where coca grows well, and probe into the alleged important role of having good access to markets for the legal crop(s), or for coca (paste), in illicit crop substitution.
