This paper studies alcohol consumption among low-income workers in India. In a 3-week field experiment, the majority of 229 cycle-rickshaw drivers were willing to forgo substantial monetary payments in order to set incentives for themselves to remain sober, thus exhibiting demand for commitment to sobriety. Randomly receiving sobriety incentives significantly reduced daytime drinking while leaving overall drinking unchanged. I find no evidence of higher daytime sobriety significantly changing labor supply, productivity, or earnings. In contrast, increasing sobriety raised savings by 50 percent, an effect that does not appear to be solely explained by changes in income net of alcohol expenditures. (JEL C93, D14, I12, J22, J24, J31, O12)Heavy alcohol consumption among male low-income workers is common in India and other developing countries. Excessive drinking can have severe consequences for individuals and their families, yet our understanding of such effects is limited. In particular, acute alcohol intoxication is thought to affect myopia and self-control, such that alcohol consumption could interfere with a variety of forward-looking decisions and behaviors. By affecting productivity, labor supply, savings decisions, and human capital investments, alcohol could reduce earnings and wealth accumulation and thus deepen poverty. However, though theoretically possible, we do not know whether such effects are present or economically meaningful in reality.
