This study considers the response of household electricity consumption to social nudges during peak load events. Our investigation considers two social nudges. The first targets conservation during peak load events, while the second promotes aggregate conservation. Using data from a natural field experiment with 42,100 households, we find that both social nudges reduce peak load electricity consumption by 2 to 4% when implemented in isolation and by nearly 7% when implemented in combination. These findings suggest an important role for social nudges in the regulation of electricity markets and a limited role for crowd out effects.

From newborns to the elderly, exposure to violence and conflict has been found to have deleterious effects. In this study, we explore a unique type of violence: exposure to the Taliban. Pairing a field experiment with a field survey among citizens in Khyber Pakhtunkhwa (KP), Pakistan, we examine how exposure to violence affects general trust, subjective well-being, and confidence in institutions. In our field experiment, we observe that exposure to conflict significantly alters the relative valuation of monetary rewards for oneself compared to those for a comparable peer. Specifically, individuals subjected to violence demonstrate a marked tendency to prioritize their own financial gain over that of a similar other. In the survey, we find that exposure to violence is associated with reduced general trust, trust in informal institutions, and subjective well-being. Interestingly, being exposed to violence increases trust in formal institutions. Our combined results highlight that the interplay between violence and trust dynamics is complex and highly consequential. In turn, the policy implications highlight the need for a multifaceted strategy to support individuals and communities affected by violence, ensuring both immediate relief and long-term resilience.

We partnered with Alaska's Pick.Click.Give. Charitable Contributions Program to implement a statewide natural field experiment with 540,000 Alaskans designed to explore whether targeted appeals emphasizing donor benefits through warm glow impact donations. Results highlight the relative import of appeals to self. Individuals who received such an appeal were 4.5 percent more likely to give and gave 20 percent more than counterparts in the control group. Yet, a message that instead appealed to recipient benefits had no effect on average donations relative to the control group. We also find evidence of long-run effects of warm glow appeals in the subsequent year.

Prosumers are becoming increasingly important in global energy consumption and production. We partner with an energy service provider in Sweden to explore the economics facing such agents by conducting a natural field experiment over a 32-month period. As a policy instrument, we explore how simple nudges affect choices on both the consumption and production sides. Importantly, with the added flexibility to influence both sides of the market, and with a rich data set that permits an analysis of intraday, intraweek, and seasonal variation, we can detail effects on overall conservation efforts, intertemporal substitution, load shifting, and net purchases from the grid. The overarching theme is that nudges have the potential to have an even greater impact on the energy market with prosumers compared to their portmanteau components.

Smart-home technologies have been heralded as an important way to increase energy conservation. While in vitro engineering estimates provide broad optimism, little has been done to explore whether such estimates scale beyond the lab. We estimate the causal impact of smart thermostats on energy use via two novel framed field experiments in which a random subset of treated households have a smart thermostat installed in their home. Examining 18 months of associated high-frequency data on household energy consumption, yielding more than 16 million hourly electricity and daily natural gas observations, we find little evidence that smart thermostats have a statistically or economically significant effect on energy use. We explore potential mechanisms using almost four million observations of system events including human interactions with their smart thermostat. Results indicate that user behavior dampens energy savings and explains the discrepancy between estimates from engineering models, which assume a perfectly compliant subject, and actual households, who are occupied by users acting in accord with behavioral economists' conjectures. In this manner, our data document a keen threat to the scalability of new user-based technologies.

This paper uses a field experiment to estimate the effects of prices and social norms on the decision to adopt and efficient technology. We find that prices and social norms influence the adoption and decision along different margins: while prices operate on both the extensive and intensive margins, social norms operate mostly through the extensive margin. This has both positive and normative implications, and suggests that economics and psychology may be strong complements in the diffusion process. To complement the reduced form results, we estimate a structural model that points to important household heterogeneity: whereas some consumers welcome the opportunity to purchase and learn about the new technology, for others the inconvenience and social pressure of the ask results in negative welfare. As a whole, our findings highlight that the design of optimal technological diffusion policies will require multiple instruments and a recognition of household heterogeneity.

This study explores whether negative income shocks from the COVID-19 pandemic affect the demand for environmental policy. By running a survey in Germany in May 2020, we show that there is a large and negative correlation between the COVID-19 income shocks and the willingness to support green policies. Importantly, this relation is separate from the effect of long-run income. Building on the first evidence, our study provides directions for future valuation studies. Specifically, our results provide a proof of concept that welfare analyses based on willingness-to-pay estimates to assess the benefits of an environmental good or the cost of an environmental damage may be downward biased if temporary changes in income are not considered.

This study develops theory and uses a door-to-door fundraising field experiment to explore the economics of charity. We approached nearly 5000 households, randomly divided into four experimental treatments, to shed light on key issues on the demand side of charitable fundraising. Empirical results are in line with our theory: in gross terms, our lottery treatments raised considerably more money than our voluntary contributions treatments. Interestingly, we find that a one standard deviation increase in female solicitor physical attractiveness is similar to that of the lottery incentive--the magnitude of the estimated difference in gifts is roughly equivalent to the treatment effect of moving from our theoretically most attractive approach (lotteries) to our least attractive approach (voluntary contributions).

This study explores the economics of charitable fund-raising. We begin by developing theory that examines the optimal lottery design while explicitly relaxing both risk-neutrality and preference homogeneity assumptions. We test our theory using a battery of experimental treatments and find that our theoretical predictions are largely confirmed. Specifically, we find that single and multiple prize lotteries dominate the voluntary contribution mechanism both in total dollars raised and the number of contributors attracted. Moreover, we find that the optimal fund-raising mechanism depends critically on the risk postures of potential contributors and preference heterogeneity.

This study develops theory and conducts an experiment to provide an understanding of why people initially give to charities, why they remain committed to the cause, and what factors attenuate these influences. Using an experimental design that links donations across distinct treatments separated in time, we present several insights. For example, we find that previous donors are more likely to give, and contribute more, than donors asked to contribute for the first time. Yet, how these previous donors were acquired is critical: agents who are initially attracted by signals of charitable quality transmitted via an economic mechanism are much more likely to continue giving than agents who were initially attracted by non-mechanism factors.

We explore collusion by using the tools of experimental economics in a naturally occurring marketplace. We report that competitive price theory adequately organizes data in multilateral decentralized bargaining markets without conspiratorial opportunities. When conspiratorial opportunities are allowed and contract prices are perfectly observed, prices (quantities) are considerably above (below) competitive levels. When sellers receive imperfect price signals, outcomes are intermediate to those of competitive markets and collusive markets with full information. Finally, experienced buyers serve as a catalyst to thwart attempts by sellers to engage in anticompetitive pricing: in periods where experienced agents transact in the market, average transaction prices are below those realized in periods where only inexperienced agents execute trades.

The economics literature suggests that enhanced social connection can increase trust amongst agents, which can ultimately lead to more efficient economic outcomes, including increased provision of public goods. This study provides a test of whether social connectedness (proxied via agent similarities in race and gender) influences giving to a charitable fundraiser. Using data gathered from more than 2000 households approached in an actual door-to-door fundraising drive, we find limited evidence of the importance of such social connections. A robust result in the data, however, is that our minority solicitors, whether approaching a majority or minority household, are considerably less likely to obtain a contribution, and conditional on securing a contribution, gift size is lower than their majority counterparts receive.

Social scientists have presented evidence that suggests discrimination is ubiquitous: women, nonwhites, and the elderly have been found to be the target of discriminatory behavior across several labor and product markets. Scholars have been less successful at pinpointing the underlying motives for such discriminatory patterns. We employ a series of field experiments across several market and agent types to examine the nature and extent of discrimination. Our exploration includes examining discrimination based on gender, age, sexual orientation, race, and disability. Using data from more than 3000 individual transactions, we find evidence of discrimination in each market. Interestingly, we find that when the discriminator believes the object of discrimination is controllable, any observed discrimination is motivated by animus. When the object of discrimination is not due to choice, the evidence suggests that statistical discrimination is the underlying reason for the disparate behavior.

One fact that has emerged in modern societies is that people help others. Whether it is donating a few dollars to help feed the poor or volunteering time to help rebuild someone's life after a natural disaster, people around the globe commonly lend a hand. This study provides an overview of that support, summarizing gifts of both time and money around the globe. We also highlight research that indicates useful ways in which we can enhance the charitable pie. Our discussion revolves around both individual giving and corporate philanthropy, but we focus on empirical insights from recent charitable fundraising field experiments in the Western World. We present information that is useful for policymakers, fundraising practitioners, and academicians.

This study examines the mechanisms underlying long-run reductions in energy consumption caused by a widely studied social nudge. Our investigation considers two channels: physical capital in the home and habit formation in the household. Using data from 38 natural field experiments, we isolate the role of physical capital by comparing treatment and control homes after the original household moves, which ends treatment. We find 35 to 55 percent of the reductions persist once treatment ends and show this is consonant with the physical capital channel. Methodologically, our findings have important implications for the design and assessment of behavioral interventions.

Several recent laboratory experiments have shown that the use of explicit incentives--such as conditional rewards and punishment--entail considerable "hidden" costs. The costs are hidden in the sense that they escape our attention if our reasoning is based on the assumption that people are exclusively self-interested. This study represents a first attempt to explore whether, and to what extent, such considerations affect equilibrium outcomes in the field. Using data gathered from nearly 3000 households, we find little support for the negative consequences of control in naturally-occurring labor markets. In fact, even though we find evidence that workers are reciprocal, we find that worker effort is maximized when we use conditional--not unconditional--rewards to incent workers.

This study showcases the usefulness of field experiments to the study of environmental and resource economics. Our focus pertains to work related to field experiments in the area of 'behavioral' environmental and resource economics. Within this rubric, we discuss research in two areas: those that inform i) benefit cost analysis and ii) conservation of resources. Within each realm, we show how field experiments have been able to test the relevant theories, provide important parameters to construct new theories, and guide policymakers. We conclude with thoughts on how field experiments can be used to deepen our understanding of important areas within environmental and resource economics.

An important dialogue between theorists and experimentalists over the past few decades has raised the study of the interaction of psychological and economic incentives from academic curiosity to a bona fide academic field. One recent area of study within this genre that has sparked interest and debate revolves around the "hidden costs" of conditional incentives. This study overlays randomization on a naturally-occurring environment in a series of temporally-linked field experiments to advance our understanding of the economics of charity and test if such "costs" exist in the field. This approach permits us to examine why people initially give to charities, and what factors keep them committed to the cause. Several key findings emerge. First, there are hidden benefits of conditional incentives that would have gone undetected had we maintained a static theory and an experimental design that focused on short run substitution effects rather than dynamic interactions. Second, we can reject the pure altruism model of giving. Third, we find that public good provision is maximized in both the short and long run by using conditional, rather than unconditional, incentives.

The tontine, which is an interesting mixture of group annuity, group life insurance, and lottery, has a peculiar place in economic history. In the seventeenth and eighteenth centuries it played a major role in raising funds to finance public goods in Europe, but today it is rarely encountered outside of a dusty footnote in actuarial course notes or as a means to thicken the plot of a murder mystery. This study provides a formal model of individual contribution decisions under a modern variant of the historical tontine mechanism that is easily implemented by private charities. Our model incorporates desirable properties of the historical tontine to develop a mechanism to fund the private provision of a public good. The tontine-like mechanism we derive is predicted to outperform not only the voluntary contribution mechanism but also another widely used mechanism: charitable lotteries. Our experimental test of the instrument provides some evidence of the beneficial effects associated with implementing tontine-like schemes. We find that the mechanism has particular power in cases where agents are risk-averse or in situations where substantial asymmetries characterize individual preferences for the public good.
