A Notion Of Prominence For Games With Natural-Language Labels, Alessandro Sontuoso, Sudeep Bhatia

ESI Working Papers

We study games with natural-language labels (i.e., strategic problems where options are denoted by words), for which we propose and test a measurable characterization of prominence. We assume that – ceteris paribus – players find particularly prominent those strategies that are denoted by words more frequently used in their everyday language. To operationalize this assumption, we suggest that the prominence of a strategy-label is correlated with its frequency of occurrence in large text corpora, such as the Google Books corpus (“n-gram” frequency). In testing for the strategic use of word frequency, we consider experimental games with different incentive structures (such …

A Simple, Ecologically Rational Rule For Settling Found Property Disputes, Bart J. Wilson

ESI Publications

Who has property in a found item X, which is contained in Y? The finder of X or the person who has property in Y? The common law says it depends. It depends upon whether the owner of Y knew about X, or whether X was lost or mislaid, or how small the weight of X is relative to Y (as compared to its value), or whether the finder was an employee of the owner of Y, to name just a few. Wilson (2020) hypothesizes that humans universally cognize property as being contained in a …

Trust And Trustworthiness In Procurement Contracts With Retainage, Matthew J. Walker, Elena Katok, Jason Shachat

ESI Working Papers

In complex procurement projects, it is difficult to write enforceable contracts that condition price upon quality. Supplier non-performance becomes an acute risk, particularly when there is intense competition for the contract. An established incentive mechanism used to mitigate the problem of supplier non-performance is retainage, in which the buyer sets aside a portion of the purchase price. After project completion, the buyer determines the amount of retainage that is released to the seller, considering any defects that arise. While generally a feasible contract form to implement, the practical difficulties in assessing completion introduce a moral hazard for the buyer. We …

Consistent Differences In A Virtual World Model Of Ape Societies, Bart J. Wilson, Sarah F. Brosnan, Elizabeth V. Lonsdorf, Crickette M. Sanz

ESI Publications

Practical and ethical constraints limit our ability to experimentally test socioecological theory in wild primates. We took an alternate approach to model this, allowing groups of humans to interact in a virtual world in which they had to find food and interact with both ingroup and outgroup avatars to earn rewards. We altered ratios and distributions of high- and low-value foods to test the hypothesis that hominoids vary with regards to social cohesion and intergroup tolerance due to their feeding ecology. We found larger nesting clusters and decreased attacks on outgroup competitors in the Bonobo condition versus the Chimpanzee condition, …

The Impact Of The Covid-19 Pandemic On Economic Behaviours And Preferences: Experimental Evidence From Wuhan, Jason Shachat, Matthew J. Walker, Lijia Wei

ESI Working Papers

We examine how the emergence of Covid-19 in Wuhan, and the ramifications of associated events, influence pro-sociality, trust and attitudes towards risk and ambiguity. We assess these influences using an experiment consisting of financially incentivized economic tasks. We establish causality via the comparison of a baseline sample collected pre-epidemic with five sampling waves starting from the imposition of a stringent lock- down in Wuhan and completed six weeks later. We find significant long-term increases - measured as the difference between the baseline and final wave average responses - in altruism, cooperation, trust and risk tolerance. Participants who remained in Wuhan …

Does Free Information Provision Crowd Out Costly Information Acquisition? It’S A Matter Of Timing, Diego Aycinena, Alexander Elbittar, Andrei Gomberg, Lucas Rentschler

ESI Working Papers

We consider the issue of how timing of provision of additional information affects information-acquisition incentives. In environments with costly attention, a sufficiently confident agent may choose to act based on the prior, without incurring those costs. However, a promise of additional information in the future may be used to encourage additional attentional effort. This may be viewed as a novel empirical implication of rational inattention. In a lab experiment designed to test this theoretical prediction, we show that promise of future “free” information induces subjects to acquire information which they would not be acquiring without such a promise.

Predictors Of Social Distancing And Mask-Wearing Behavior: Panel Survey In Seven U.S. States, Plamen Nikolov, Andreas Pape, Ozlem Tonguc, Charlotte Williams

Economics Faculty Scholarship

This paper presents preliminary summary results from a longitudinal study of participants in seven U.S. states during the COVID-19 pandemic. In addition to standard socio-economic characteristics, we collect data on various economic preference parameters: time, risk, and social preferences, and risk perception biases. We pay special attention to predictors that are both important drivers of social distancing and are potentially malleable and susceptible to policy levers. We note three important findings: (1) demographic characteristics exert the largest influence on social distancing measures and mask-wearing, (2) we show that individual risk perception and cognitive biases exert a critical role in influencing …

New Kid On The Blockchain: The Rise Of Cryptocurrency In The Global Arena: Humanitarian Usage With Blockchain, Rhonda S. Binda

Open Educational Resources

In 2018, the world was shaken by the fast rise of Bitcoin and other cryptocurrencies that use a decentralized, blockchain technology for payment transfers outside of the traditional banking system. The potential impact this alternative form of banking could have in the medium and long term on the over 2 billion people globally unbanked is tremendous. Additionally, blockchain itself is being used for value transfer combined with bio and genetic tagging technologies in refugee camps for example, bringing to rise a new era where technology for development is disrupting education, healthcare and security programs globally.

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. Murray, Sharon C. Sanchez-Franco, Shannon C. Montgomery, Joaquín Jaramillo, Christopher Tate, Rajnish Kumar, Laura Dunne, Abhijit Ramalingam, Erik O. Kimbrough, Erin Krupka, Huiyu Zhou, Laurence Moore, Linda Bauld, Blanca Llorente, Olga L. Sarmiento, Frank Kee

Economics Faculty Articles and Research

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) …

The Property Species: Mine, Yours, And The Human Mind, Bart J. Wilson

Economics Faculty Books and Book Chapters

"Arguing that neither the sciences nor the humanities synthesizes a full account of property, the book offers a cross-disciplinary compromise that is sure to be controversial: Property is a universal and uniquely human custom. Integrating cognitive linguistics with philosophy of property and a fresh look at property disputes in the common law, the book makes the case that symbolic-thinking humans locate the meaning of property within a thing. That is, all human beings and only human beings have property in things, and at its core, property rests on custom, not rights. Such an alternative to conventional thinking contends that the …

Essays On Climate Change-Related Extreme Events, Alvin E. Harris

Dissertations

There are increasing and urgent calls for global economies to join in the fight against the impacts of climate change (World Bank, 2020). With reports such as the World Bank (2020) of climate change costing billions of dollars in losses for economies, the purpose of my dissertation is to examine the effects of climate change-related extreme events and their potential economic effects in three areas: agriculture, migration, and the labor market.

My first essay focuses on the factors that influence farmers’ perception of risk and adaptive strategies against the effects of climate change-related extreme events. I examine whether farmers’ social …

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 …

The Impact Of Taxes And Wasteful Government Spending On Giving, Roman Sheremeta, Neslihan Uler

ESI Working Papers

We examine how taxes impact charitable giving and how this relationship is affected by the degree of wasteful government spending. In our model, individuals make donations to charities knowing that the government collects a flat-rate tax on income (net of charitable donations) and redistributes part of the tax revenue. The rest of the tax revenue is wasted. The model predicts that a higher tax rate increases charitable donations. Surprisingly, the model shows that a higher degree of waste decreases donations (when the elasticity of marginal utility with respect to consumption is high enough). We test the model’s predictions using a …

The Economics Of Babysitting A Robot, Aleksandr Alekseev

ESI Working Papers

I study the welfare effect of automation on workers in a setting where technology is complementary but imperfect. Using a modified task-based framework, I argue that imperfect complementary automation can impose non-pecuniary costs on workers via a behavioral channel. The theoretical model suggests that a critical factor determining the welfare effect of imperfect complementary automation is the automatability of the production process. I confirm the model's predictions in an experiment that elicits subjects' revealed preference for automation. Increasing automatability leads to a significant increase in the demand for automation. I explore additional drivers of the demand for automation using machine …

Immune Function During Pregnancy Varies Between Ecologically Distinct Populations, Carmen Hové, Benjamin C. Trumble, Amy S. Anderson, Jonathan Stieglitz, Hillard Kaplan, Michael Gurven, Aaron Blackwell

ESI Publications

Background and objectives

Among placental mammals, females undergo immunological shifts during pregnancy to accommodate the fetus (i.e. fetal tolerance). Fetal tolerance has primarily been characterized within post-industrial populations experiencing evolutionarily novel conditions (e.g. reduced pathogen exposure), which may shape maternal response to fetal antigens. This study investigates how ecological conditions affect maternal immune status during pregnancy by comparing the direction and magnitude of immunological changes associated with each trimester among the Tsimane (a subsistence population subjected to high pathogen load) and women in the USA.

Methodology

Data from the Tsimane Health and Life History Project (N = 935) and …

Public Leaderboard Feedback In Sampling Competition: An Experimental Investigation, Stanton Hudja, Brian Roberson, Yaroslav Rosokha

ESI Working Papers

We investigate the role of performance feedback, in the form of a public leaderboard, in a sequential-sampling contest with costly observations. The player whose sequential random sample contains the observation with the highest value wins the contest and obtains a prize with a fixed value. We find that there exist parameter configurations such that in the subgame perfect equilibrium of contests with a fixed ending date (i.e., finite horizon), providing public performance feedback results in fewer expected observations and a lower expected value of the winning observation. We conduct a controlled laboratory experiment to test the theoretical predictions, and find …

Trust, Reciprocity, And Social History: New Pathways Of Learning When Max U (Own Reward) Fails Decisively, Vernon L. Smith

ESI Working Papers

"This evaluation begins with the BDM protocol—itself a methodological contribution—and the experimental findings. The question of the replicability and robustness of these unexpected results is addressed next in a summary of two subsequent experimental papers. We follow with a discussion of two attempts to explain qua understand the BDM findings; both, however, have methological deficiencies—Reciprocity and Social Preference explanations. Finally, we offer a brief on Adam Smith’s (1759; 1853; hereafter in the text, Sentiments) model of human sociability, based on strictly self-interested actors, that culminates in propositions that (1) account for trust game choices, and (2) predict action in new …

Forecasting Skills In Experimental Markets: Illusion Or Reality?, Brice Corgnet, Cary Deck, Mark Desantis, David Porter

ESI Working Papers

Using experimental asset markets, we study the situation of a financial analyst who is trying to infer the fundamental value of an asset by observing the market’s history. We find that such capacity requires both standard cognitive skills (IQ) as well as social and emotional skills. However, forecasters with high emotional skills tend to perform worse when market mispricing is high as they tend to give too much emphasis to the noisy signals from market data. By contrast, forecasters with high social skills perform especially well in markets with high levels of mispricing in which their skills could help them …
