AbstractThis research project will test for and quantify the existence of surplus labor---individuals who are involuntarily rationed out of the wage labor market---in low income communities. In both the U.S. and in developing countries, many social programs are predicated on the idea of surplus labor; yet there has not been an empirical test of its existence. The research will use field experiments which involve creating many industry jobs in a nearby city to test the labor surplus theory in a rural setting. If rural workers can be absorbed into these factory jobs without any change in the wage or employment levels in the rural labor market, then this will demonstrate the existence of surplus labor. A pilot study of 36 local labor markets provides initial support for the existence of labor surplus in low income communities. The results of this research will provide a better explanation of the functioning of labor markets in low income and high unemployment communities, and therefore provide guidance on crafting policies to reduce unemployment or to combat the effects of such high unemployment rates. In addition, by revealing which types of self-employed small entrepreneurs would prefer wage work, the findings have implications for how to better target programs to enable small business growth in high unemployment settings. The results will be central to understanding many issues in development economics and will have applications in several fields of economics, such as labor economics, public economics, and industrial policy. By improving the functioning of the U.S. labor market, the results thus improve U.S. competitiveness. This research project uses field experiments to obtain revealed preference estimates of labor rationing in rural labor markets, using rural labor markets in India as the test bed. A large labor demand shock will be created by recruiting up to about 30 percent of workers in surrounding villages to work in nearby factory jobs. If the amount of labor rationing is at least as big as the demand shock, then there will be: (i) no effect on local village level wages, (ii) no change in local village employment, and (iii) positive employment spillovers on workers who do not receive factory jobs. In addition, a supplementary experiment will be conducted to estimate the short run elasticity of supply of labor, in order to check whether labor supply is perfectly elastic. Examination of who benefits from unemployment spillovers can be used to explain the two possible components of labor rationing---voluntary unemployment and disguised unemployment. Finally, comparing traditional survey-based measures of unemployment to these revealed preference estimates can help provide some validation of the reliability of traditional survey measures. The results of this research provide strong microeconomic foundations of labor market rationing and provide guidance for labor market policies in both low income and developed countries.

摘要本研究计画将测试并量化低收入社区中剩余劳动力的存在，剩余劳动力是指非自愿地被排除在工资劳动力市场之外的个体。 在美国和发展中国家，许多社会计划都是以剩余劳动力的概念为前提的;然而，还没有一个实证检验它的存在。 这项研究将使用实地实验，包括在附近的城市创造许多工业就业机会，以检验农村环境中的劳动力剩余理论。 如果在农村劳动力市场的工资和就业水平没有变化的情况下，农村劳动力能够被吸收到这些工厂的工作岗位上，那么这就证明了剩余劳动力的存在。对36个地方劳动力市场的试点研究为低收入社区存在劳动力过剩提供了初步支持。 这项研究的结果将为低收入和高失业社区的劳动力市场的运作提供更好的解释，从而为制定减少失业或应对高失业率影响的政策提供指导。 此外，通过揭示哪种类型的自营职业的小企业家更喜欢工资工作，研究结果对如何更好地定位计划，使小企业在高失业率环境中增长具有影响。研究结果将是理解发展经济学中许多问题的核心，并将在经济学的几个领域，如劳动经济学，公共经济学和产业政策的应用。 通过改善美国劳动力市场的运作，结果提高了美国的竞争力。 本研究以印度的农村劳动力市场为研究对象，通过实地实验来获得农村劳动力市场中劳动力配给的偏好估计。 一个巨大的劳动力需求冲击将通过在周边村庄招募多达30%的工人到附近的工厂工作来创造。 如果劳动力配给的数量至少与需求冲击一样大，那么将有：（i）对当地村庄水平的工资没有影响，（ii）当地村庄的就业没有变化，（iii）对没有得到工厂工作的工人产生积极的就业溢出效应。 此外，为了检验劳动力供给是否具有完全弹性，还将进行一个估计劳动力供给短期弹性的补充实验。 考察失业溢出的受益者可以用来解释劳动力配给的两种可能的组成部分-自愿失业和变相失业。 最后，比较传统的基于调查的失业措施，这些显示偏好估计可以帮助传统的调查措施的可靠性提供一些验证。本文的研究结果为劳动力市场配给提供了强有力的微观经济基础，并为低收入国家和发达国家的劳动力市场政策提供了指导。
