Who Helps Tsimane Children And Adults?, Eric Schniter, Daniel K. Cummings, Paul L. Hooper, Maguin Gutierrez Cayuba, Jonathan Stieglitz, Benjamin C. Trumble, Hillard S. Kaplan, Michael D. Gurven

ESI Working Papers

We consider several forms of helping behavior among Tsimane Amerindians of Bolivia, including provision of shelter, childcare, food, sickcare, loans, advice, and cultural influence. While kin selection theory is traditionally invoked to explain nepotistic nurturing of youngsters by closely related kin, much less attention has been given to understanding the help provided to children and adults by individuals without close genetic relatedness. To explain who provides the various forms of help that we consider, we evaluate support for several predictions derived from kin selection theory: that helpers are most often closely related and from an older generation, provide more help …

Ambiguity And Ambiguity Attitudes Across Auctions, Cary Deck, Paan Jindapon, Tigran Melkonyan, Mark Schneider

ESI Working Papers

Studies of ambiguity perceptions and attitudes are moving beyond the Ellsberg urn to examine people’s responses to ambiguity in naturally occurring events, games, and financial markets. In this study, we measure ambiguity perceptions and attitudes for market prices and allocations in four classical auction formats (first-price and second-price sealed bid auctions, English and Dutch clock auctions). We find ambiguity attitudes, representing individual preferences, are stable across auctions. However, the perceived ambiguity surrounding auction prices is lowest for English clock auctions which are obviously strategyproof (OSP), followed by second-price auctions which are strategyproof (SP), followed by a tie between first-price and …

Cognitive Abilities And Individual Earnings In Hybrid Continuous Double Auctions, Yan Peng, Jason Shachat, Lijia Wei, S. Sarah Zhang

ESI Working Papers

We study the influence of cognitive abilities, in particular reaction time, trader intuition (Theory of Mind), and cognitive reflection abilities, on human participants’ individual earnings when competing alongside algorithmic traders in continuous double auctions. In balanced markets, where each human trader has an algorithmic trader clone with the same valuations or costs, faster human reaction time significantly improves trading performance, while Theory of Mind can be detrimental to human trading performance, particularly for sellers. For unbalanced markets with humans and algorithmic traders on opposite sides of the market, the effects of cognitive abilities depend on trader role as well as …

Coordinated And Uncoordinated Punishment In A Team Investment Game, Vicente Calabuig, Natalia Jiménez-Jiménez, Gonzalo Olcina, Ismael Rodriguez-Lara

ESI Publications

Coordinated punishment occurs when punishment requires a specific number of punishers to be effective, otherwise, no damage will be inflicted on the target. While societies often rely on this punishment device, its benefits are unclear compared to uncoordinated punishment, where punishment decisions are substitutes. In this paper, we compare the efficacy of coordinated and uncoordinated punishment in a team investment game with two investors and one allocator. Our findings indicate that coordinated punishment results in higher levels of cooperation and reciprocity, as measured by the levels of joint investment and the return by allocators. Importantly, this does not translate into …

How Does Passive Investing Effect The Informational Efficiency Of Prices?, Brice Corgnet, Mark Desantis, Yan Peng, David Porter, Jason Shachat

ESI Working Papers

We investigate the causal effects of passive investing on informational efficiency and market quality metrics by developing a novel laboratory experiment that introduces Index trackers with exogenous passive investment flows. We find that, while improving liquidity, Index tracking hurts informational efficiency, confirming our main hypothesis. Furthermore, we observe violations of the law of one price, leading to widespread and persistent arbitrage opportunities. Additionally, our research uncovers that Active traders, particularly those with private information about asset values and high cognitive ability, reap benefits from the introduction of Index tracking.

Embracing Diversity In Agricultural Economics, Timothy L. Meyer

Cornhusker Economics

To steal an overused cliché, “There’s room in the tent for everyone.” Over the 2023 academic year, I have reiterated this message to all my students, with one addition. Not only is there room for everyone, but all are invited AND welcome. Food is something we all have in common, no matter the background. I think this is why producers in the state of Nebraska feel as strongly as they do about the food they produce; it is life-giving and should be taken seriously. Nebraska Agriculture is part of what makes our state great, and that is not a secret …

Sleep Restriction Alters The Integration Of Multiple Information Sources In Probabilistic Decision-Making, Jeryl Y. L. Lim, Johanna M. Boardman, Clare Anderson, David L. Dickinson, Daniel Bennett, Sean P. A. Drummond

ESI Publications

The detrimental effects of sleep loss on overall decision-making have been well described. Due to the complex nature of decisions, there remains a need for studies to identify specific mechanisms of decision-making vulnerable to sleep loss. Bayesian perspectives of decision-making posit judgement formation during decision-making occurs via a process of integrating knowledge gleaned from past experiences (priors) with new information from current observations (likelihoods). We investigated the effects of sleep loss on the ability to integrate multiple sources of information during decision-making by reporting results from two experiments: the first implementing both sleep restriction (SR) and …

Representation And Bracketing In Repeated Games, Mouli Modak

ESI Working Papers

In this experimental paper, the author investigates the framing effect of different representations of multiple strategic settings or games on a player’s strategic behavior. Two representations of the same environment are employed, wherein a player engages in two infinitely repeated prisoner’s dilemma games. In the first representation (termed Split), the stage games are shown separately. In contrast, the second representation (termed Linked) displays a combined stage game. The choice bracketing, distinguishing between Narrow and Broad bracketing, is considered a potential cause behind any disparity in behavior between the two representations. The Split representation does not necessitate broad bracketing, whereas the …

How Personalized Networks Can Limit Free Riding: A Multi-Group Version Of The Public Goods Game, Aaron S. Berman, Laurence R. Iannaccone, Mouli Modak

ESI Working Papers

People belong to many different groups, and few belong to the same network of groups. Moreover, people routinely reduce their involvement in dysfunctional groups while increasing involvement in those they find more attractive. The net effect can be an increase in overall cooperation and the partial isolation of free-riders, even if free-riders are never punished, excluded, or recognized. We formalize and test this conjecture with an agent-based social simulation and a multi-good extension of the standard repeated public goods game. Our initial results from three treatments suggest that the multi-group setting indeed raises overall cooperation and dampens the impact of …

Personal Lies, Gary Charness, Ismael Rodriguez-Lara

ESI Working Papers

Using the mind game, we provide experimental evidence that people are more likely to lie when they disclose non-personal information (e.g., reporting a number they thought of) compared with personal information (e.g., reporting the last digit of their birth year). Our findings suggest that the type of information is an important factor for lying behavior.

Financial Contagion And Financial Lockdowns, Gabriele Camera, Alessandro Gioffré

ESI Working Papers

Extreme financial shocks often elicit extraordinary policy interventions that preclude financial activity on a large scale, for example as the 1933 U.S. “bank holiday.” We study these interventions using a random matching framework where the financial contagion process is explicit and the diffusion of the initial shock can be analytically characterized. The study suggests that there is scope for forced closures of individual firms or even economy-wide financial lockdowns only when firms are financially vulnerable and policy institutions are not well-functioning. Here, ordinary policy alone cannot prevent or sufficiently mitigate contagion, while complementing it with a lockdown or individual closures …

Evolution Of Primate Vocal Repertoires: Vocalization Systems As Embodied Capital For Mediating Within-Group Conflict, Eric Schniter, Mateo Peñaherrera-Aguirre

ESI Working Papers

Phylogenetic studies of communication help us understand evolutionary changes that led to human language – a form of primate communication, extraordinarily complex in terms of its varied vocalizations. Here we describe the macro-evolutionary role of life history traits on primate vocalization systems, informing our understanding of the relationships between social complexity and primate vocal repertoire size. We reviewed the primatological literature and collected information on the vocal repertoire size, social conflict, group size, endocranial volume, and maximum longevity of 42 non-human primate species. We conducted a set of analyses to examine the role of these factors on the macroevolution of …

Human-Robot Interactions: Insights From Experimental And Evolutionary Social Sciences, Eric Schniter

ESI Working Papers

"Experimental research in the realm of human-robot interactions has focused on the behavioral and psychological influences affecting human interaction and cooperation with robots. A robot is loosely defined as a device designed to perform agentic tasks autonomously or under remote control, often replicating or assisting human actions. Robots can vary widely in form, ranging from simple assembly line machines performing repetitive actions to advanced systems with no moving parts but with artificial intelligence (AI) capable of learning, problem-solving, communicating, and adapting to diverse environments and human interactions. Applications of experimental human-robot interaction research include the design, development, and implementation of …

Enlightenment Ideals And Belief In Progress In The Run-Up To The Industrial Revolution: A Textual Analysis, Ali Almelhem, Murat Iyigun, Austin Kennedy, Jared Rubin

ESI Working Papers

Using textual analysis of 173,031 works printed in England between 1500 and 1900, we test whether British culture evolved to manifest a heightened belief in progress associated with science and industry. Our analysis yields three main findings. First, there was a separation in the language of science and religion beginning in the 17th century. Second, scientific volumes became more progress-oriented during the Enlightenment. Third, industrial works—especially those at the science-political economy nexus—were more progress-oriented beginning in the 17th century. It was therefore the more pragmatic, industrial works which reflected the cultural values cited as important for Britain’s takeoff.

Joining A Currency Union To Improve Financial Development And Competitiveness: The Case Of Slovakia, Etsub Tekola Jemberu, Bruce Dehning

Accounting Faculty Articles and Research

Enhancing competitiveness is a priority for nations seeking to promote economic growth. One of the critical drivers of a nation’s sustainable competitiveness is financial system development. However, whether joining a currency union has a positive impact on a country’s financial system development requires further investigation. This study evaluates the impact of euro adoption on Slovakia’s financial system development using a synthetic control method with lasso regularization methodology. A comprehensive index that captures the depth, access, and efficiency of financial institutions and markets is used to measure financial system development. Based on a donor pool composed of non-euro OECD countries, the …

The Effect Of Wage Proposals On Efficiency And Income Distribution☆, Lara Ezquerra, Joaquín Gómez-Miñambres, Natalia Jiminez, Praveen Kujal

ESI Publications

Pre-play non-binding communication in organizations is prevalent. We study the implications of pre-play, private and public, wage proposals in labor markets. To that end, we develop a theoretical model from which we derive certain hypothesis that we test through a laboratory experiment. In the baseline, that depicts a typical labor market interaction, the employer makes a wage offer to the worker who may then accept or reject it. In subsequent treatments, workers, moving first, make private, non-binding, wage proposals to the employer. In a following treatment, the proposals are made public. Our findings suggest that both private and public wage …

Suggested Versus Extended Gifts: How Alternative Market Institutions Mitigate Moral Hazard, Daniel Houser, Jason Shachat, Weiwei Zheng

ESI Working Papers

Gift exchange can partially mitigate supply-side moral hazard, even in anonymous market interactions. In a market where quality is not fully contractable, the amount that a price exceeds the market-clearing price for the lowest quality is a gift from the buyer. We show that the gift formation process, inextricably linked with a market institution’s price formation process, greatly influences the size and effectiveness of the gift. When the market institution dictates that prices are formed by bids posted by buyers, the gift is extended to the seller. When the market institution dictates that prices are formed by offers posted by …

Match Stability With A Costly And Flexible Number Of Positions, James Gilmore, David Porter

ESI Working Papers

One of the primary objectives of two-sided matching systems is to facilitate the pairing of two groups of agents in a manner that eliminates any incentive for pair deviation. Such challenges are quite prevalent and can have significant and long-lasting ramifications for participants, including students applying to colleges. While much of the existing research in this field addresses the problem using fixed quotas, real-world applications, like college admissions, demonstrate that this is not always applicable. We introduce the concept of slot stability, recognizing the potential motivation for organizations to modify their quotas after the matching process. We propose two algorithms …

Religion And Growth, Sascha O. Becker, Jared Rubin, Ludger Woessmann

ESI Working Papers

We use the elements of a macroeconomic production function—physical capital, human capital, labor, and technology—together with standard growth models to frame the role of religion in economic growth. Unifying a growing literature, we argue that religion can enhance or impinge upon economic growth through all four elements because it shapes individual preferences, societal norms, and institutions. Religion affects physical capital accumulation by influencing thrift and financial development. It affects human capital through both religious and secular education. It affects population and labor by influencing work effort, fertility, and the demographic transition. And it affects total factor productivity by constraining or …

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 …

Metapopulation Dynamics Of Sars-Cov-2 Transmission In A Small-Scale Amazonian Society, Thomas Kraft, Edmond Seabright, Sarah Alami, Samuel M. Jenness, Paul L. Hooper, Bret Beheim, Helen Davis, Daniel K. Cummings, Daniel Eid Rodriguez, Maguin Gutierrez Cayuba, Emily J. Miner, Xavier De Lamballerie, Lucia Inchauste, Stéphane Priet, Benjamin Trumble, Jonathan Stieglitz, Hillard Kaplan, Michael Gurven

ESI Publications

The severity of infectious disease outbreaks is governed by patterns of human contact, which vary by geography, social organization, mobility, access to technology and healthcare, economic development, and culture. Whereas globalized societies and urban centers exhibit characteristics that can heighten vulnerability to pandemics, small-scale subsistence societies occupying remote, rural areas may be buffered. Accordingly, voluntary collective isolation has been proposed as one strategy to mitigate the impacts of COVID-19 and other pandemics on small-scale Indigenous populations with minimal access to healthcare infrastructure. To assess the vulnerability of such populations and the viability of interventions such as voluntary collective isolation, we …

Apolipoprotein-Ε4 Is Associated With Higher Fecundity In A Natural Fertility Population, Benjamin Trumble, Mia Charifson, Tom Kraft, Angela R. Garcia, Daniel K. Cummings, Paul L. Hooper, Amanda J. Lea, Daniel Eid Rodriguez, Stephanie V. Koebele, Kenneth Buetow, Bret Beheim, Riana Minocher, Maguin Gutierrez, Gregory S. Thomas, Margaret Gatz, Jonathan Stieglitz, Caleb E. Finch, Hillard Kaplan, Michael Gurven

ESI Publications

In many populations, the apolipoprotein-ε4 (APOE-ε4) allele increases the risk for several chronic diseases of aging, including dementia and cardiovascular disease; despite these harmful effects at later ages, the APOE-ε4 allele remains prevalent. We assess the impact of APOE-ε4 on fertility and its proximate determinants (age at first reproduction, interbirth interval) among the Tsimane, a natural fertility population of forager-horticulturalists. Among 795 women aged 13 to 90 (20% APOE-ε4 carriers), those with at least one APOE-ε4 allele had 0.3 to 0.5 more children than (ε3/ε3) …

Group Identity And The Formation Of Conditional Social Preferences Among Chinese Youth, Timo Heinrich, Jason Shachat, Qinjuan Wan

ESI Working Papers

Con icts between local and migrant populations have been ubiquitous in modern China. We examine the potential for longer-term amelioration of this conflict through successive generations and intergroup contact within integrated schooling. We adopt the perspective that in- and out-group biased behaviour structurally arises from group conditional social preferences. We assess the group-conditional social preferences of local and migrant children in a second-tier Chinese city, Xiamen, and the extent these preferences correlate with those of their parents. We find that local students have a greater likelihood of Egalitarian preferences and a lower likelihood of Generous preferences when allocating with locals …

Energetic Costs Of Testosterone In Two Subsistence Populations, Benjamin C. Trumble, Herman Pontzer, Jonathan Stieglitz, Daniel K. Cummings, Brian Wood, Melissa Emery Thompson, David Raichlen, Bret Beheim, Gandhi Yetish, Hillard Kaplan, Michael Gurven

ESI Publications

Objective

Testosterone plays a role in mediating energetic trade-offs between growth, maintenance, and reproduction. Investments in a high testosterone phenotype trade-off against other functions, particularly survival-enhancing immune function and cellular repair; thus only individuals in good condition can maintain both a high testosterone phenotype and somatic maintenance. While these effects are observed in experimental manipulations, they are difficult to demonstrate in free-living animals, particularly in humans. We hypothesize that individuals with higher testosterone will have higher energetic expenditures than those with lower testosterone.

Methods

Total energetic expenditure (TEE) was quantified using doubly labeled water in n = 40 Tsimane forager-horticulturalists …

Discrete Rule Learning In First Price Auctions, Jason Shachat, Lijia Wei

ESI Working Papers

We present a hidden Markov model of discrete strategic heterogeneity and learning in first price independent private values auctions. The model includes three latent bidding rules: constant absolute mark-up, constant percentage mark-up, and strategic best response. Rule switching probabilities depend upon a bidder's past auction outcomes and a myopic reinforcement learning dynamic. We apply this model to a new experiment that varies the number of bidders and the auction frame between forward and reverse. We find the proportion of bidders following constant absolute mark-up increases with experience, and is higher when the number of bidders is large. The primary driver …

Endogenous Political Legitimacy: The Tudor Roots Of England’S Constitutional Governance, Avner Greif, Jared Rubin

ESI Working Papers

This paper highlights the importance of endogenous changes in the foundations of legitimacy for political regimes. It focuses on the central role of legitimacy changes in the rise of constitutional monarchy in England. It first defines legitimacy and briefly elaborates a theoretical framework enabling a historical study of this unobservable variable. It proceeds to substantiate that the low-legitimacy, post-Reformation Tudor monarchs of the 16th century promoted Parliament to enhance their legitimacy, thereby changing the legislative process from the “Crown and Parliament” to the “Crown in Parliament” that still prevails in England.

To address claims of human exceptionalism, we determine where humans fit within the greater mammalian distribution of reproductive inequality. We show that humans exhibit lower reproductive skew (i.e., inequality in the number of surviving offspring) among males and smaller sex differences in reproductive skew than most other mammals, while nevertheless falling within the mammalian range. Additionally, female reproductive skew is higher in polygynous human populations than in polygynous nonhumans mammals on average. This patterning of skew can be attributed in part to the prevalence of monogamy in humans compared to the predominance of polygyny in nonhuman mammals, to the limited …

21st Century Political Agronomy: Between Collapse And Apocalypse In The Capitalist World System, Harrison Raskin

Honors Scholar Theses

Examinations of the causal chain between ecological impacts and food shortages reveal significant impending global disturbances. This paper draws a causal link between ecological impacts and low food productivity which will lead to food insecurity and economic crises in the near term. Further, this paper argues that food insecurity may lead to the collapse of the capitalist world system. This threat is contrasted with “business as usual” climate models which, rather than depicting the collapse of the capitalist world system, depict its persistence throughout the collapse of the world ecology.

Believe It Or Not: Discovering The Role Of Marketplace Ministry In Reconciling Race And Religion In The African American Church, Shawn Burgs

DMin Project Theses

This Doctor of Ministry Project explores the experiences of African Americans as faith holders in the crux of race, religion, and marketplace and how the interconnectedness of these facets can lend to reconciliation. The purpose of exploring how African American believers experience race and religious reconciliation is a noble goal that seeks to address the challenges faced by many African American believers in navigating their faith and cultural engagement. By examining their experiences, insights, and perspectives, we can learn more about the unique challenges they face and the strategies they employ to overcome them. This information can help us develop …

Performance Expectancy And Use Of Social Media For Marketing By Staff Of Selected Publishing Firms In South-West, Nigeria, Osarobu E. Igudia Dr, Solomon Tosin Ogunsina Mr

Library Philosophy and Practice (e-journal)

Social media are platforms through which people of the different networks create, share and exchange information, ideas and also market products such as books in a virtual community. They are instruments for communication that do not just pass information but interact with customers. Since many benefits are derivable from the use of social media for marketing, it becomes imperative to investigate how book marketers use social media to achieve the objectives of their organisations. This study adopted a descriptive research design of correlational type. The population of the study was 212 marketing and sales staff of selected publishing firms. The …
