Economic Policy and Technology Choice of Heterogeneous Producers
本文构建了一个异质性生产者内生技术选择模型，分析气候变化和政策如何影响发展中国家农村小农的生产决策，并以越南咖啡生产为例，发现冲击的次级效应可能超过初始影响。
This article introduces a new Hopenhayn-Melitz-type model of heterogeneous producers with endogenous technology choice. Different from previous trade models, it describes smallholder producers in rural areas of developing countries in the context of environment and development economics. Shocks (climate change) and various policies affect the producers’ endogenous choice between market entry or exit and between simple or advanced technology. This adds new margins of adjustment to models used in this context. Based on these mechanisms, the theoretical analysis identifies a novel type of the rebound effect via market entry. The numerical application to coffee production in rural Vietnam shows that secondary effects of the shocks, such as changes in the number of producers, can be larger than the original impact. Technology-supporting policies can have unintended detrimental side effects on less productive producers.
