Spillovers from Behavioral Interventions: Experimental Evidence from Water and Energy Use

This paper provides experimental evidence that behavioral interventions spill over to untreated sectors by altering consumer choice. We use a randomized controlled trial and high-frequency data to test the eect of social norms messaging about residential water use on electricity consumption. Messaging induces a 1.3 to 2.2% reduction in summertime electricity use. Empirical tests and household survey data support the hypothesis that this nudge alters electricity choices. An engineering simulation suggests that complementarities between appliances that use water and electricity can explain only 26% of the electricity reduction. Incorporating the cross-sectoral spillover increases the cost-eectiveness of the intervention by 62%

Utilities Included: Split Incentives in Commercial Electricity Contracts

The largest decile of commercial electricity customers comprises half of commercial sector electricity usage. We quantify a substantial split incentives problem that exists when these large firms are on electricity-included property lease contracts. Using exogenous variation in weather shocks, we show that customers on tenant-paid contracts use 6-14% less electricity in summer months. The policy implications are promising. Nationwide energy savings from aligning incentives for the largest 10% of commercial customers exceeds analogous savings from the entire residential electricity sector. It is also cost-effective: switching to tenant-paid contracts via sub-metering has a private payoff period of under one year

The Dynamic Impacts of Pricing Groundwater

This paper evaluates own-price dynamics in taxing environmental externalities. We exploit a natural experiment that exposed some firms to a large and persistent price increase for groundwater, a setting characterized by incomplete markets. Using five years of post-treatment data on farm-level water use, we find that water conservation doubles between the first and fifth year of the tax. Failure to account for dynamics in policies designed to manage groundwater will mischaracterize the price elasticity of demand and introduce efficiency costs

Climate Change and Labor Markets in Rural Mexico: Evidence from Annual Fluctuations in Weather

This paper evaluates the effects of annual fluctuations in temperature and precipitation on labor allocation in rural Mexico. We use a 28-year panel of individuals to investigate how people adjust their sector and location of work in response to year-to-year variation in weather. Controlling for state-year and individual fixed effects, we find that individuals are less likely to work locally in years with a high occurrence of extreme heat. This reduction in labor occurs for both agricultural and non-agricultural jobs, with larger reductions among wage workers. Extreme heat early in the year or for individuals located close to the U.S. border increases the likelihood that individuals respond by migrating to the United States. Under two medium-emissions climate change scenarios, our results imply that increased temperatures will lead to a 1.2-3% decrease in local employment and a 1-2% increase in domestic migration from rural to urban areas. These results provide an important example of how climate change could impact rural labor markets in developing countries
