On The Stability Of Norms And Norm-Following Propensity: A Cross-Cultural Panel Study With Adolescents, Erik O. Kimbrough, Erin L. Krupka, Rajnish Kumar, Jennifer M. Murray, Abhijit Ramalingam, Sharon Sánchez‑Franco, Olga L. Sarmiento, Frank Kee, Ruth F. Hunter

Economics Faculty Articles and Research

Norm-based accounts of social behavior in economics typically reflect tradeoffs between maximization of own consumption utility and conformity to social norms. Theories of norm-following tend to assume that there exists a single, stable, commonly known injunctive social norm for a given choice setting and that each person has a stable propensity to follow social norms. We collect panel data on 1468 participants aged 11–15 years in Belfast, Northern Ireland and Bogotá, Colombia in which we measure norms for the dictator game and norm-following propensity twice at 10 weeks apart. We test these basic assumptions and find that norm-following propensity is …

Cultural Evolution: A Review Of Theoretical Challenges, Ryan Nichols, Mathieu Charbonneau, Azita Chellappoo, Taylor Davis, Miriam Haidle, Erik O. Kimbrough, Henrike Moll, Richard Moore, Thom Scott-Phillips, Benjamin Grant Purzycki, Jose Segovia-Martin

Economics Faculty Articles and Research

The rapid growth of cultural evolutionary science, its expansion into numerous fields, its use of diverse methods, and several conceptual problems have outpaced corollary developments in theory and philosophy of science. This has led to concern, exemplified in results from a recent survey conducted with members of the Cultural Evolution Society, that the field lacks ‘knowledge synthesis’, is poorly supported by ‘theory’, has an ambiguous relation to biological evolution and uses key terms (e.g. ‘culture’, ‘social learning’, ‘cumulative culture’) in ways that hamper operationalization in models, experiments and field studies. Although numerous review papers in the field represent and categorize …

Crossing The Line: Evidence For The Categorization Theory Of Spatial Voting, Mark Pickup, Erik O. Kimbrough, Eline A. De Rooij

Economics Faculty Articles and Research

Bølstad and Dinas (2017) propose a model of spatial voting, based on social identity theory, that suggests supporting a candidate/policy on the other side of the ideological spectrum has a disutility that is not accounted for by common spatial models. Unfortunately, the data they use cannot speak directly to whether the disutility arises because individuals perceive their ideology as a social identity. We present the results of an experimental study that measures the norm against crossing the ideological spectrum; tests the cost of doing so, controlling for spatial effects; and demonstrates that this cost increases with the salience and strength …

Selection Homophily And Peer Influence For Adolescents’ Smoking And Vaping Norms And Outcomes In High And Middle-Income Settings, Jennifer M. Murray, Sharon Sánchez-Franco, Olga L. Sarmiento, Erik O. Kimbrough, Christopher Tate, Shannon C. Montgomery, Rajnish Kumar, Laura Dunne, Abhijit Ramalingam, Erin L. Krupka, Felipe Montes, Huiyu Zhou, Laurence Moore, Linda Bauld, Blanca Llorente, Frank Kee, Ruth F. Hunter

Economics Faculty Articles and Research

The MECHANISMS study investigates how social norms for adolescent smoking and vaping are transmitted through school friendship networks, and is the first study to use behavioral economics methodology to assess smoking-related social norms. Here, we investigate the effects of selection homophily (the tendency to form friendships with similar peers) and peer influence (a social process whereby an individual’s behavior or attitudes are affected by peers acting as reference points for the individual) on experimentally measured smoking and vaping norms, and other smoking outcomes, in adolescents from high and middle-income settings. Full school year groups in six secondary schools in Northern …

The Impact Of Vaccinations And Chronic Disease On Covid Death Rates, James L. Doti

Economics Faculty Articles and Research

This study presents a theoretical and empirical regression model to measure the efficacy of vaccinations in reducing COVID death rates across states over the 3/10/21 to 12/28/22 period. During that period, it was estimated that the availability of vaccinations resulted in a reduction of 427,000 COVID deaths in the nation. To arrive at that estimate, other covariants were held constant. In particular, it was found that chronic disease should be included as an explanatory variable to arrive at unbiased measures of the efficacy of vaccinations in reducing deaths. In addition, the percentage of people over the age of 65 was …

Connecting Higher Education To Workplace Activities And Earnings, Hung Chau, Sarah H. Bana, Baptiste Bouvier, Morgan R. Frank

Economics Faculty Articles and Research

Higher education is a source of skill acquisition for many middle- and high-skilled jobs. But what specific skills do universities impart on students to prepare them for desirable careers? In this study, we analyze a large novel corpora of over one million syllabi from over eight hundred bachelors’ granting US educational institutions to connect material taught in higher education to the detailed work activities in the US economy as reported by the US Department of Labor. First, we show how differences in taught skills both within and between college majors correspond to earnings differences of recent graduates. Further, we use …

God Games: An Experimental Study Of Uncertainty, Superstition, And Cooperation, Aidin Hajikhameneh, Laurence R. Iannaccone

Economics Faculty Articles and Research

This paper uses a novel lab experiment to test claims about the origins and functions of religion. We modify the standard public goods game, adding a computer-based agent that adjusts earnings in ways that might depend on players' contributions. Our treatments employ three different descriptions of the adjustment process that loosely correspond to monotheistic, atheistic, and agnostic interpretations of the computer's role. The adjustments neither mask players' contributions nor magnify their impact. Yet players in all three adjustment treatments contribute much more than those who play the standard public goods game. Players' contributions and survey responses show that adjustments induce …

Optimal Patent Licensing—Two Or Three-Part Tariff, Swapnendu Banerjee, Arijit Mukherjee, Sougata Poddar

Economics Faculty Articles and Research

We look into technology transfer by an insider patentee in a spatial duopoly model under three types of licensing contracts—(i) two-part tariff with fixed fee and per-unit royalty, (ii) two-part tariff with fixed fee and ad-valorem royalty and (iii) general three-part tariff with fixed fee, per-unit and ad-valorem royalties. Under two-part tariff contracts, the licenser is better off with the per-unit royalty contract but the general contract does better than the other contracts. In contrast to the existing literature, all three licensing contracts may make the consumers worse-off compared to no licensing, with the lowest consumer surplus achieved under the …

The Personality And Cognitive Traits Associated With Adolescents’ Sensitivity To Social Norms, Christopher Tate, Rajnish Kumar, Jennifer M. Murray, Sharon Sanchez-Franco, Olga L. Sarmiento, Shannon C. Montgomery, Huiyu Zhou, Abhijit Ramalingam, Erin Krupka, Erik Kimbrough, Frank Kee, Ruth F. Hunter

Economics Faculty Articles and Research

Little is known about the personality and cognitive traits that shape adolescents’ sensitivity to social norms. Further, few studies have harnessed novel empirical tools to elicit sensitivity to social norms among adolescent populations. This paper examines the association between sensitivity to norms and various personality and cognitive traits using an incentivised rule-following task grounded in Game Theory. Cross-sectional data were obtained from 1274 adolescents. Self-administered questionnaires were used to measure personality traits as well as other psychosocial characteristics. Incentivised rule-following experiments gauged sensitivity to social norms. A series of multilevel mixed effects ordered logistic regression models were employed to assess …

The Symbolic Work Of Prices, Akash Miharia, Jan Osborn, Bart J. Wilson

Economics Faculty Articles and Research

We posit that prices are signs, not just signals, that work in the same symbolic way as words. Both are complex, generative systems of shared meaning that rely on a web of intricate symbolic references. Just like the meaning of a word is a product of our social and linguistic action, the meaning of a price is a product of our relationship to the physical world phenomena of people in markets. The fundamental conception of both is to communicate and construct worlds with ourselves and others, enabling us to act in the world. Prices, like words, do symbolic work.

Hybrid U-Net: Semantic Segmentation Of High-Resolution Satellite Images To Detect War Destruction, Shima Nabiee, Matthew Harding, Jonathan Hersh, Nader Bagherzadeh

Economics Faculty Articles and Research

Destruction caused by violent conflicts play a big role in understanding the dynamics and consequences of conflicts, which is now the focus of a large body of ongoing literature in economics and political science. However, existing data on conflict largely come from news or eyewitness reports, which makes it incomplete, potentially unreliable, and biased for ongoing conflicts. Using satellite images and deep learning techniques, we can automatically extract objective information on violent events. To automate this process, we created a dataset of high-resolution satellite images of Syria and manually annotated the destroyed areas pixel-wise. Then, we used this dataset to …

The Efficiency Of U.S. Public Space Utilization During The Covid-19 Pandemic, Seth G. Benzell, Avinash Collis, Christos Nicolaides

Economics Faculty Articles and Research

The COVID-19 pandemic has called for and generated massive novel government regulations to increase social distancing for the purpose of reducing disease transmission. A number of studies have attempted to guide and measure the effectiveness of these policies, but there has been less focus on the overall efficiency of these policies. Efficient social distancing requires implementing stricter restrictions during periods of high viral prevalence and rationing social contact to disproportionately preserve gatherings that produce a good ratio of benefits to transmission risk. To evaluate whether U.S. social distancing policy actually produced an efficient social distancing regime, we tracked consumer preferences …

The Cultural Transmission Of Trust Norms: Evidence From A Lab In The Field On A Natural Experiment, Elira Karaja, Jared Rubin

Economics Faculty Articles and Research

We conduct trust games in three villages in a northeastern Romanian commune. From 1775–1919, these villages were arbitrarily assigned to opposite sides of the Austrian and Ottoman/Russian border despite being located seven kilometers apart. This plausibly exogenous border assignment affected local institutions and late-18th century migration in a manner that likely also affected trust. Conditional on trust norms being affected by these centuries-old historical circumstances, our experimental design tests the degree to which such norms are transmitted intergenerationally. Consistent with theoretical predictions, we find that participants on the Austrian side that also have family roots in the village are indeed …

A Network Of Thrones: Kinship And Conflict In Europe, 1495–1918, Seth G. Benzell, Kevin Cooke

Economics Faculty Articles and Research

We construct a database linking European royal kinship networks, monarchies, and wars to study the effect of family ties on conflict. To establish causality, we exploit decreases in connection caused by apolitical deaths of rulers' mutual relatives. These deaths are associated with substantial increases in the frequency and duration of war. We provide evidence that these deaths affect conflict only through changing the kinship network. Over our period of interest, the percentage of European monarchs with kinship ties increased threefold. Together, these findings help explain the well-documented decrease in European war frequency.

Monitoring War Destruction From Space Using Machine Learning, Hannes Mueller, Andre Groeger, Jonathan Hersh, Andrea Matranga, Joan Serrat

Economics Faculty Articles and Research

Satellite imagery is becoming ubiquitous. Research has demonstrated that artificial intelligence applied to satellite imagery holds promise for automated detection of war-related building destruction. While these results are promising, monitoring in real-world applications requires high precision, especially when destruction is sparse and detecting destroyed buildings is equivalent to looking for a needle in a haystack. We demonstrate that exploiting the persistent nature of building destruction can substantially improve the training of automated destruction monitoring. We also propose an additional machine-learning stage that leverages images of surrounding areas and multiple successive images of the same area, which further improves detection significantly. …

Infanticide And Human Self Domestication, Erik O. Kimbrough, Gordon M. Myers, Arthur J. Robson

Economics Faculty Articles and Research

"Our hypothesis, which is largely complementary to Wrangham, is that band elders engaged in infanticide and direct and indirect child homicide against the offspring of reactive aggressive adults through decisions during the foraging period of the Middle and Upper Pleistocene. We hypothesize that elders may have targeted the offspring of reactively aggressive males (and females) as retaliation for behaviors that were not good for the elders or their offspring and because surreptitiously killing the offspring of violent males was much less dangerous to the elders than killing the violent males. Such retaliation could have selected against reactive aggression as a …

Examining The Impact Of Socioeconomic Variables On Covid-19 Death Rates At The State Level, James L. Doti

Economics Faculty Articles and Research

This study uses a step-wise regression model to identify the socioeconomic variables most significant in explaining COVID-19 death rates on a state-level basis. The regression tests cover the 1/1/2020 to 12/1/2020 period as well as the first and second halves of 2020. This study also uses the Oxford stringency index to measure more precisely the efficacy of governmental mandates at the state level. The results in this study rigorously showed that while the density variables were the most significant explanatory variables during the first half of the year, their significance fell during the second half. Use of the Oxford stringency …

Benefit-Cost Analysis Of Covid-19 Policy Intervention At The State And National Level, James L. Doti

Economics Faculty Articles and Research

This study analyzes the benefits of statewide policy intervention in reducing COVID-19 deaths and the costs of that intervention in lost jobs and lower real gross state product (RGSP). Policy interventions are measured by the Oxford stringency index which places a daily numerical value on the level of a state’s policy intervention.

Empirical evidence is provided that shows policy interventions have reduced COVID-19 deaths by 375,000 lives in 2020. On the cost side, it was found that policy intervention resulted in a loss of 7.3 million jobs and a decline of $410 billion in RGSP.

The study concludes by integrating …

A Model To Explain Statewide Differences In Covid-19 Death Rates, James L. Doti

Economics Faculty Articles and Research

COVID-19 death rates per 100,000 vary widely across the nation. As of September 1, 2020, they range from a low of 4 in Hawaii to a high of 179 in New Jersey. Although academic research has been conducted at the county and metropolitan levels, no research has rigorously examined or identified the demographic and socioeconomic forces that explain state-level differences. This study presents an empirical model and the results of regression tests that help identify these forces and shed light on the role they play in explaining COVID-19 deaths.

A stepwise regression model we tested exhibits a high degree of …

Introduction To The Special Issue On The Economics Of Religion, Jared Rubin

Economics Faculty Articles and Research

"The economics and political science of religion have blossomed into full-fledged fields in the last decade and a half. What was once a field on the far outskirts of economics and political science now regularly publishes in its top journals (see Figure 1).¹ By 1998, the field was large enough for Iannaccone (1998) to write a survey of the shape of the field. The field was very much at its infancy at that time, and most of the best work was done by sociologists and/or published in sociology journals. This has changed significantly in the 22 years since Iannaccone's …

Technology Transfer In Spatial Competition When Licensees Are Asymmetric, Sougata Poddar, Swapnendu Banerjee, Monalisa Ghosh

Economics Faculty Articles and Research

We study technology transfer in a spatial competition with two asymmetric licensees (firms) with an outside innovator who decides how many licenses to offer and the optimal licensing contract. We show the optimal licensing policy is pure royalty contract to both licensees leading to a complete diffusion of the new technology. The result holds irrespective of the cost differentials between the licensees and for innovation of all sizes, that is, drastic or non‐drastic. This robust finding although supports the dominance of royalty licensing in practice; however, consumers may not be necessarily better off. We also throw light on the situation …

Mechanisms Study: Using Game Theory To Assess The Effects Of Social Norms And Social Networks On Adolescent Smoking In Schools—Study Protocol, Ruth F. Hunter, Felipe Montes, Jennifer M.

This proof of concept study harnesses novel transdisciplinary insights to contrast two school-based smoking prevention interventions among adolescents in the UK and Colombia. We compare schools in these locations because smoking rates and norms are different, in order to better understand social norms based mechanisms of action related to smoking. We aim to: (1) improve the measurement of social norms for smoking behaviors in adolescents and reveal how they spread in schools; (2) to better characterize the mechanisms of action of smoking prevention interventions in schools, learning lessons for future intervention research. The A Stop Smoking in Schools Trial (ASSIST) …

Opportunity Cost, Inattention And The Bidder's Curse, David J. Freeman, Erik O. Kimbrough, J. Philipp Reiss

Economics Faculty Articles and Research

Auction winners sometimes suffer a “bidder’s curse”, paying more for an item at auction than the fixed price charged for an identical item by other sellers. This seemingly irrational behavior is puzzling because the information necessary to avoid overpaying would appear to be readily available to bidders, yet they seem to ignore it. To understand this behavior, we consider the bidders’ decisions whether to acquire information about the fixed price before bidding, in the presence of opportunity costs. Our theory introduces costly information acquisition into an auction model, with a fixed price aftermarket selling an identical good. When information about …

Rationing Social Contact During The Covid-19 Pandemic: Transmission Risk And Social Benefits Of Us Locations, Seth G. Benzell, Avinash Collis, Christos Nicolaides

Economics Faculty Articles and Research

To prevent the spread of coronavirus disease 2019 (COVID-19), some types of public spaces have been shut down while others remain open. These decisions constitute a judgment about the relative danger and benefits of those locations. Using mobility data from a large sample of smartphones, nationally representative consumer preference surveys, and economic statistics, we measure the relative transmission reduction benefit and social cost of closing 26 categories of US locations. Our categories include types of shops, entertainments, and service providers. We rank categories by their trade-off of social benefits and transmission risk via dominance across 13 dimensions of risk and …

Identity And The Self-Reinforcing Effects Of Norm Compliance, Mark A. Pickup, Erik O. Kimbrough, Eline A. Rooij

Economics Faculty Articles and Research

When making political and economic decisions (e.g., voting, donating money to a cause), individuals consider the expectations of groups with which they identify. These expectations are injunctive norms, shared beliefs about appropriate behavior for identity group members, and individuals' choices reflect trade‐offs between adherence to these norms and other preferences. We show that when those who identify moderately/strongly with the group pay a cost as a consequence of avoiding a norm violation, they subsequently view the norms as stronger than those that paid no cost. This is evident in their greater willingness to pay an additional cost to punish/reward other …

Kinship, Fractionalization And Corruption, Mahsa Akbari, Duman Bahrami-Rad, Erik O. Kimbrough

Economics Faculty Articles and Research

We examine the roots of variation in corruption across societies, and we argue that marriage practices and family structure are an important, overlooked determinant of corruption. By shaping patterns of relatedness and interaction, marriage practices influence the relative returns to norms of nepotism/favoritism versus norms of impartial cooperation. In-marriage (e.g. consanguineous marriage) generates fractionalization because it yields relatively closed groups of related individuals and thereby encourages favoritism and corruption. Out-marriage creates a relatively open society with increased interaction between non-relatives and strangers, thereby encouraging impartiality. We report a robust association between in-marriage practices and corruption both across countries and within …

Differences In Tsimane Children’S Growth Outcomes And Associated Determinants As Estimated By Who Standards Vs. Within-Population References, Melanie Martin, Aaron Blackwell, Hillard Kaplan, Michael Gurven

Economics Faculty Articles and Research

Anthropometric measures are commonly converted to age stratified z-scores to examine variation in growth outcomes in mixed-age and sex samples. For many study populations, z-scores will differ if calculated from World Health Organization (WHO) growth standards or within-population references. The specific growth reference used may influence statistical estimates of growth outcomes and their determinants, with implications for biological inference. We examined factors associated with growth outcomes in a sample of 152 Tsimane children aged 0–36 months. The Tsimane are a subsistence-scale population in the Bolivian Amazon with high rates of infectious disease and growth faltering. To examine the influence of …
