本文研究了家庭非传统农业出口的长期福利效应。我们使用跨越1985-2005年的面板数据集，并采用差中差估计来调查非传统农业出口对危地马拉中部高地家庭消费状况和资产状况变化的长期影响。鉴于采用模式的异质性，该分析根据考虑到非传统农业出口采用的时间和持续时间的家庭分类区分了影响估计。结果表明，虽然平均而言，所有家庭的福利水平都有所提高，而不管收养状况和持续时间如何，但改善的程度因群体而异。长期采用者在过去的二十年中表现出最小的增长，尽管有一些早期的收益。相反，那些从20世纪80年代繁荣时期获益后退出非传统农业出口生产的早期采采者，在耐用资产头寸和住房条件方面的表现比其他任何类别都要好，表现出更大的改善。
This article documents the long-term welfare effects of household nontraditional agricultural export (NTX) adoption. We use a panel dataset that spans the period 1985-2005, and employ difference-in-differences estimation to investigate the long-term impact of nontraditional agricultural export adoption on changes in household consumption status and asset position in the Central Highlands of Guatemala. Given the heterogeneity in adoption patterns, the analysis differentiates the impact estimates based on a classification of households that takes into account the timing and duration of nontraditional agricultural export adoption. The results show that while, on average, welfare levels have improved for all households irrespective of adoption status and duration, the extent of improvement has varied across groups. Long-term adopters exhibit the smallest increase in the lapse of two decades, in spite of some early gains. Conversely, early adopters who withdrew from nontraditional agricultural export production after reaping the benefits of the boom period of the 1980s are found to have fared better and shown greater improvements in durable asset position and housing conditions than any other category.
