Private Input Suppliers as Information Agents for Technology Adoption in Agriculture
研究发现，在发展中国家，相比政府推广，告知私人投入品供应商关于新种子品种的信息能使农民采纳率提高50%以上，供应商更主动地告知潜在客户并增加高回报农户的采纳。
Information frictions limit the adoption of new agricultural technologies in developing countries. Efforts to improve learning involve spreading information from government agents to farmers. We show that when compared to this government approach, informing private input suppliers in India about a new seed variety increases farmer-level adoption by over 50 percent. Suppliers become more proactive in informing potential customers and carrying the new variety. They induce increased adoption by those with higher returns from the technology. Being motivated by expanded sales offers the most likely motive for these results.
