农业家庭模型——其中生产决策与消费决策同时做出——是许多发展模型的核心。对这类同时性选择进行实证建模并非易事。绝大多数实证研究假定农户的行为如同市场是完备的:在这种情况下,决策简化为一个递归系统,其中消费选择可被视为在生产决策全部完成之后做出。以往对这一假定的实证检验依赖于对生产决策施加限制。我们提出了一种基于家庭消费选择的新的检验方法,并利用印度尼西亚农村的数据实施了该程序。相对于生产侧的检验,基于消费的检验非常适合识别任何情境下行为与完备市场相一致的农户,以及该假定被拒绝的农户。我们发现,递归假定对于较大的农户未被拒绝,但对于小农户则被拒绝。这些检验易于实施,其结果为识别家庭在市场不完备情况下所采取的行为提供了新的机会。
Abstract
The agricultural household model, in which decisions about production and consumption are made simultaneously, lies at the heart of many models of development. Empirically modelling these simultaneous choices is not straightforward. The vast majority of empirical studies assume that farm-households behave as if markets are complete: in that case decision-making simplifies to a recursive system where consumption choices can be treated as if they are made after all production decisions. Previous empirical tests of this assumption have relied on restrictions on production decisions. We develop a new approach to testing based on household consumption choices and implement the procedure using data from rural Indonesia. Relative to production-side tests, the consumption-based test is well-suited to identifying those farm-households in any setting whose behavior is consistent with complete markets and those for whom the assumption is rejected. We find the recursion assumption is not rejected for larger farmers but is rejected for small farmers. The tests are straightforward to implement and the results of the tests provide new opportunities to identify the behaviors that households adopt in the face of incomplete markets.
