Food wasted in primary and secondary education institutions creates nutritional losses, financial inefficiencies, and environmental degradation. While there is some evidence of how particular interventions within schools may influence the amount of waste created, there is little recent information about typical levels of food waste observed in U.S....
Article
Date labels have been implicated as a driver of premature discard of food by consumers, which has led to recommendations to change date labels as a way to reduce food waste. However, most proposed date label reform has focused on changing the phrase that accompanies the date on the label, and not how the date is selected. To explore the relative im...

Three successive administrations have supported the United States' 2015 goal to reduce food waste. Households waste more food than other supply chain segments, however, few data sources are available to track US households' progress toward this goal. We provide insights from the first four waves of a novel national survey designed to track such was...
Article
Communities are increasingly interested in bolstering sustainability by implementing local campaigns to reduce wasted food and divert it from landfills. Evaluation can be challenging, however, as community-engaged interventions may reach all community members, making it difficult to find an appropriate control group. We leverage a recently validate...
Article
Diet change and food waste reduction are key levers for meeting climate change goals, but little is known about pursuing policies to shape both behaviors simultaneously. In a between-subjects field experiment, we randomly assign distinct cognitive and behavioral nudges focused on increasing vegetable consumption and decreasing food waste among food...
Preprint
The proliferation of personal, household and workplace sensors and devices has created individual environments rich with purposeful and incidental feedback capable of altering behavior. We formulate an empirical learning model suitable for understanding individual behavioral responses in such environments. We estimate this model using data collecte...
Article
There is growing concern whether pro-environmental behavioral interventions can generate sufficient reductions in carbon emissions to address climate change. While many have suggested enhanced tailoring of interventions to increase effect sizes, and while individual tailoring is common among health interventions, little is known about how individua...
Article
Currently, 40% of food produced in the U.S. is never eaten, leading to lost resources, economic costs, decreased food security, and the wasted food itself, which has immense climate and ecological impacts. However, unwanted food can be leveraged towards sustainability aims by, for example, diverting high-quality surplus to food-insecure communities...
Article
Ugly foods meet nutritional and safety benchmarks but deviate from cosmetic and size standards. The marketability of ugly food is a major factor that frustrates field-level food rescue efforts. We investigate opportunities to promote ugly foods in a way that converts uniform negative preferences towards ugly food to more diverse and horizontally di...
Article
Background Improving Americans’ selection and consumption of vegetables without increasing food waste is 1 approach to help meet global health and environmental targets outlined in the 2030 Agenda for Sustainable Development. Objective To test nudges and educational messaging on consumer vegetable consumption and food waste. Study Design, Setting...

Perhaps no phenomenon has so quickly and radically altered household production parameters and daily food patterns as the onset of the COVID‐19 pandemic. We contemplate the immediate and longer‐term implications of this public health crisis on the amount of food wasted by consumers. We conclude that the pandemic and its aftermath may improve househ...
Article
The ongoing evolution of food waste trends and the intensification of livestock systems in developing economies play a critical role in shaping global sustainability. We explore the linkage between food waste and livestock systems at the household level and how this connection changed in China during the 1990s and 2000s when market liberalization w...
Article
It is estimated that nearly one-third of food produced on the planet never meets its intended purpose of human nourishment. This represents a substantial stock of resources available for reallocation. Any potential reallocation of resources raises ethical issues – who should sacrifice (change current behaviors), who should benefit, and what methods...
Article
Full-text available
A leading factor in the creation of avoidable household food waste is confusion about food date labels. In the United States, date labels are largely unregulated, resulting in a plethora of date label phrases used in commerce. Federal regulation has been proposed but never passed, while both industry and government have provided voluntary guidance...
Article
U.S. households waste a substantial quantity of food and are advised to better manage purchasing and storage of perishable foods as a means to reduce food waste. However, little research exists concerning the contents and management of home refrigerators, which are central to most advice regarding home food waste reduction. We survey U.S. consumers...
Article
Roughly one-third of edible food produced in the world is wasted, that is, it is never consumed by humans, despite the persistent demands for nutrition throughout the world. The American Marketing Association defines marketing as “…the activity, set of institutions, and processes for creating, communicating, delivering, and exchanging offerings tha...

Despite their status as the largest and most systematic of government programs to promote local foods in the US, few studies identify the factors that are associated with the school district decision to participate in farm to school (FTS) programs. We are the first to leverage the USDA's Farm to School Census to analyze factors associated with FTS...
Article
Many countries strive to reduce food waste, which deprives hungry people of nutrition, depletes resources, and accounts for substantial greenhouse gas emissions. Composting and other food waste recycling technologies that divert food waste from landfills mitigate the environmental damages of food waste disposal and have grown in popularity. We expl...

Labels address a market failure - asymmetric information - through costly expenditures borne by consumers, firms, and taxpayers. In this review, we explore when mandatory and voluntary labeling policies may be socially optimal. Although the analysis ostensibly revolves around simple comparisons of labeling costs and the subsequent benefits from imp...
Article
We study postpartum decisions about paid work and breastfeeding using a simultaneous equations model. For our sample of higher socioeconomic status mothers, we find a joint decision process for three sets of decisions modeled: work leave duration and duration of any, as well as of exclusive, breastfeeding, and daily work hours and daily breastfeedi...
Article
We analyze recent and intended transactions of used farm equipment and find the quality of buyers' relationships with local equipment dealers influences whether their most recent purchase came from an Internet source and whether they will consider future purchases from Internet sources. We find local dealers who provide excellent parts and repair s...
Article
We analyse how age and cognitive skills are related to risk tolerance among respondents to the National Longitudinal Survey of Youth between 1993 and 2006. Older individuals display lower risk tolerance than younger individuals, though as the panel ages from their early thirties to their mid-forties, differences in risk tolerance between the oldest...
Article
Human vaccines against several common foodborne pathogens are being developed and could substantially alter consumer and producer behaviour in the markets for foods commonly afflicted by these pathogens. To understand the possible impacts of such an innovation, we derive and calibrate a partial‐equilibrium model using parameters for consumer vaccin...
Article
Vaccines against several common foodborne pathogens are being developed and could substantially alter the policy tools available to address foodborne illness. However, little analysis is available to suggest how social welfare would be affected by consumer and industry responses to these new vaccines. To address this void, we use stated-preference...
Article
We find sale prices and net revenues received by sellers in the Midwestern club-pig market are higher at traditional face-to-face auctions than at comparable Internet auctions. The comparison overcomes endogenous selection issues that commonly plague such analyses by using data from sellers that allocated pigs to both markets based on exogenous dif...
Article
The US Department of Agriculture applies a cost-of-illness approach to value reductions in morbidity, which may understate the projected benefits from proposed food-safety improvements by ignoring costs such as pain, suffering and worry. We use a national survey with a hypothetical food-choice experiment to estimate a more comprehensive measure of...
Article
Return to work is associated with diminished breastfeeding. Although more mothers breastfeed after returning to work compared to a decade ago, research has not documented the variations in breastfeeding initiation and duration based on full-time and part-time (less than 35h/week) work status. In this study, we clarify these differences. Longitudina...
Article
Rising female labor force participation in the United States may interfere with achievement of the nation’s breastfeeding goals. Meanwhile the importance of breastfeeding in developed countries is increasingly emphasized. In 1997, the American Academy of Pediatrics increased the recommended minimum duration for breastfeeding from 6 to 12 months bas...

Return to work is associated with diminished breastfeeding intensity and duration. Although more mothers breastfeed after returning to work now than earlier, research has not documented the strategies that mothers use for combining paid work and breastfeeding or their effect on breastfeeding outcomes. This study examined which strategies are associ...
Article
Two opposing viewpoints exist in the literature; some suggest consumers are unconcerned and do not desire any genetically modified labeling, while others indicate the opposite. The mixed results may be because consumers make finer distinctions than surveys have called for, and have evaluation schemes sensitive to information about the benefits and...
Article
The labelling of genetically modified (GM) foods is an important policy issue, as consumers' attitudes towards these foods appear to be quite sensitive to information about their potential benefits and risks. Because it is difficult for labels to differ across consumers, differences in reactions to label information could lead to conflicts across c...

Article
Increasingly, foods are marketed as "locally grown." We use stated preference data from a choice-based conjoint instrument to address two issues surrounding consumer demand for locally produced goods: (1) what is the geographical extent of "local," and (2) is the value consumers place on "local" production distinct from other factors that are often...

Article
A model of vertical product differentiation is used to analyze the labeling of credence goods, focusing on the manner by which quality is communicated. The results indicate that firms prefer private labeling options. In addition, firms may hire private certifiers as well as paying for mandated government labels when the government's quality benchma...
Article
We use economic experiments to examine the nature of relational trading under a menu of incomplete contracts ranging from the repeat purchase mechanism of Klein and Leffler (1981) to highly incomplete contracts that are completely unenforceable by third-parties. Our results suggest that, with barriers to complete contracting, increasing the degree...
Article
We study panel data on three birth-year cohorts to understand the changes in risk tolerance across different age groups. Interval regression models on cross-sectional data for each birth cohort are constructed to investigate how time-invariant factors and macroeconomic events such as September 11, 2001, might influence individuals' risk tolerance....
Article
We use economic experiments to investigate how different contract enforcement regimes affect efficiency and the distribution of surplus in a vertically coordinated market with buyer concentration. We find that if a third party (e.g., government) perfectly enforces contracts, social efficiency is enhanced. We also find that when third-party enforcem...
Article
We analyze responses to a survey designed to elicit consumer reaction to various approaches to labeling genetically modified (GM) foods. Consumers were shown sample labels that differed with respect to claims concerning the presence and potential effects of GM ingredients and the agency that certified these claims. A sample of 1898 US consumers rat...

Experimental economics is used to investigate two important hypotheses proposed in the economics literature on tournaments. Specifically, we test for a hypothesized “disincentives effect” which can occur in tournaments with mixed ability agents. We also test the well known hypothesis that, when common shocks are an important source of risk, tournam...
