Human Capital and Climate Change
Addressing climate change requires individual behavior change and voter support for pro-climate policies, yet surprisingly little is known about how to achieve these outcomes. In this paper, we estimate causal effects of additional education on pro-climate outcomes using new compulsory schooling law data across 20 European countries. We analyze effects on pro-climate beliefs and behaviors, as well as novel data on policy preferences and voting fo…
Quality signaling and demand for renewable energy technology: Evidence from a randomized field experiment
Solar technologies have been associated with private and social returns, but their technological potential often remains unachieved because of persistently low demand for high-quality products. In a randomized field experiment in Senegal, we assess the potential of three types of quality signaling to increase demand for high-quality solar lamps. We find no effect on demand when consumers are offered a money-back guarantee but increased demand wit…
Modeling the impact of a supervised consumption site on HIV and HCV transmission among people who inject drugs in three counties in California, USA
Our models suggest that SCS is an important intervention to enable HCV elimination and could help end the HIV epidemic among PWID in California. It could also have additional benefits such facilitating pathways into drug treatment programs and preventing fatal overdose
Regional Research-Practice-Policy Partnerships in Response to Climate-Related Disparities: Promoting Health Equity in the Pacific
Although climate change poses a threat to health and well-being globally, a regional approach to addressing climate-related health equity may be more suitable, appropriate, and appealing to under-resourced communities and countries. In support of this argument, this commentary describes an approach by a network of researchers, practitioners, and policymakers dedicated to promoting climate-related health equity in Small Island Developing States an…
The unintended impacts of agricultural fires: Human capital in China
The Effect of Pollution on Worker Productivity: Evidence from Call Center Workers in China
We investigate the effect of pollution on worker productivity in the service sector by focusing on two call centers in China. Using precise measures of each worker’s daily output linked to daily measures of pollution and meteorology, we find that higher levels of air pollution decrease worker productivity. These results manifest themselves at levels of pollution commonly found in large cities throughout the developing and developed world. (JEL J2…
Particulate Pollution and the Productivity of Pear Packers
We study the effect of outdoor air pollution on the productivity of indoor workers at a pear-packing factory. Increases in fine particulate matter (PM 2.5 ), a pollutant that readily penetrates indoors, leads to significant decreases in productivity, with effects arising at levels below air quality standards. In contrast, pollutants that do not travel indoors, such as ozone, have little, if any, effect on productivity. This effect of outdoor poll…
Temperature and the Allocation of Time: Implications for Climate Change
We estimate the impacts of temperature on time allocation by exploiting plausibly exogenous variation in temperature over time within counties. Temperature increases at the higher end of the distribution reduce hours worked in industries with high exposure to climate and reduce time allocated to outdoor leisure for the nonemployed, with this time reallocated to indoor leisure. At the lower end of the distribution, time allocated to labor is nonre…
Environment, Health, and Human Capital
In this review, we discuss three major contributions economists have made to our understanding of the relationship between the environment and individual well-being. First, in explicitly recognizing how optimizing behavior, particularly in the form of residential sorting, can lead to nonrandom assignment of pollution, economists have employed a wide range of quasi-experimental techniques to develop causal estimates of the effect of pollution. Sec…
The Impact of Pollution on Worker Productivity
This paper assesses the impact of pollution on worker productivity by relating exogenous daily variations in ozone with productivity of agricultural workers as recorded under piece rate contracts. We find robust evidence that ozone levels well below federal air quality standards have a significant impact on productivity. These results suggest that, in contrast to common characterizations of environmental protection as a tax on producers, environm…
Health and Labor Supply in the Context of HIV/Aids: The Long-Run Economic Impacts of Antiretroviral Therapy
Using longitudinal survey data collected in Kenya, this paper estimates the longer-term impacts of antiretroviral therapy (ART) on the labor supply of treated adults and their household members. Building upon previous work in Kenya, data collected from 2004-2006 indicate that early evidence on the short-run impacts of ART tends to be upheld over the long-term as well. The results show that the labor supply response among treated adults occurs rap…
Mobile phone technologies improve adherence to antiretroviral treatment in a resource-limited setting: A randomized controlled trial of text message reminders
OBJECTIVE: There is limited evidence on whether growing mobile phone availability in sub-Saharan Africa can be used to promote high adherence to antiretroviral therapy (ART). This study tested the efficacy of short message service (SMS) reminders on adherence to ART among patients attending a rural clinic in Kenya. DESIGN: A randomized controlled trial of four SMS reminder interventions with 48 weeks of follow-up. METHODS: Four hundred and thirty…
Incentives and creativity: Evidence from the academic life sciences
Despite its presumed role as an engine of economic growth, we know surprisingly little about the drivers of scientific creativity. We exploit key differences across funding streams within the academic life sciences to estimate the impact of incentives on the rate and direction of scientific exploration. Specifically, we study the careers of investigators of the Howard Hughes Medical Institute (HHMI), which tolerates early failure, rewards long‐te…
Superstar Extinction
We estimate the magnitude of spillovers generated by 112 academic "superstars" who died prematurely and unexpectedly, thus providing an exogenous source of variation in the structure of their collaborators' coauthorship networks. Following the death of a superstar, we find that collaborators experience, on average, a lasting 5% to 8% decline in their quality-adjusted publication rates. By exploring interactions of the treatment effect with a vari…
US Pharmacists' Effect as Team Members on Patient Care: Systematic Review and Meta-Analyses
BACKGROUND: One approach postulated to improve the provision of health care is effective utilization of team-based care including pharmacists. OBJECTIVE: The objective of this study was to conduct a comprehensive systematic review with focused meta-analyses to examine the effects of pharmacist-provided direct patient care on therapeutic, safety, and humanistic outcomes. METHODS: The following databases were searched from inception to January 2009…
Days of haze: Environmental information disclosure and intertemporal avoidance behavior
Modeling health insurance expansions: Effects of alternate approaches
Estimates of the costs and consequences of many types of public policy proposals play an important role in the development and adoption of particular policy programs. Estimates of the same, or similar, policies that employ different modeling approaches can yield widely divergent results. Such divergence often undermines effective policymaking. These problems are particularly prominent for health insurance expansion programs. Concern focuses on pr…
