Introduction

Rural Transformation

◮ The process of development is defined by structural transformation (Lewis, 1954) ◮ Requires a transition from subsistence to commercial agriculture (Collier & Dercon, 2014) ◮ Commercialization entails:

◮ Increased farm size ◮ Increased productivity ◮ Increased market participation

◮ Should result in greater income for (surviving) farmers

Introduction

Production Constraints

◮ Farmers face numerous production constraints that limit their ability to commercialize

◮ Lack access to credit (Berg, 2013; Stephens & Barrett, 2011) ◮ Produce below the production frontier (Hanna et al., 2014; Sherlund et al., 2002) ◮ Face price uncertainty due to limited access to output markets (de Janvry et al., 1991; LaFave & Thomas, 2016)

Introduction

Contract Farming

◮ Vertical coordination between producer and processor

◮ Integrates farmer into the market ◮ Shifts price risk and capital expenses to processor

◮ Production contracts have become a popular mechanism

◮ Barrett et al. (2012), Bellemare & Bloem (2018), and Ton et al. (2018) review literature ◮ Maertens & Vande Velde (2017) in Benin

◮ To date, almost no RCT evidence on impact of contract farming

◮ Ashraf et al. (2009) - failed export crops scheme

Conclusions

Implications

◮ Contracts with extension services appear to generate little to no value for farmers, under-performing the other contracts ◮ Contracts that provide input loans typically have the largest positive effect, especially in terms of income ◮ But contracts with just a price guarantee frequently produce results indistinguishable from contracts with input loans ◮ Appears that once farmers are insulated from price risk, they can solve their capital constraints and reduce their technical inefficiency ◮ Processors can potentially greatly reduce their operating costs by just offering contracts with a guaranteed price
