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 …

Possible Role Of The One-Half Heuristic In Overconfidence Research, Vojtěch Zíka

ESI Working Papers

Overconfidence research often involves estimating performance within a fixed range. Recent studies suggest that overprecision is affected by central tendency bias, the tendency to estimate near the center of a perceived distribution. This paper examines whether a similar pattern influences the other two overconfidence types, overestimation and overplacement. In a laboratory experiment (N = 120), participants estimated their own and the average performance over five rounds of ten Rock–Paper–Scissors games. Each round earned for up to 40 points, but average performance varied across three treatments, with means of 16.6, 20, and 23.3 points. The main question was whether this manipulation …

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.

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 …

Poor Oral Health Is Associated With Inflammation, Aortic Valve Calcification, And Brain Volume Among Forager-Farmers, Benjamin C. Trumble, Matthew Schwartz, Andrew T. Ozga, Gary T. Schwartz, Christopher M. Stojanowski, Carrie L. Jenkins, Thomas Kraft, Angela R. Garcia, Daniel K. Cummings, Paul L. Hooper, Daniel Eid Rodriguez, Kenneth Buetow, Bret Beheim, Andrei Irimia, Gregory S. Thomas, Randall C. Thompson, Horus Team, Margaret Gatz, Jonathan Stieglitz, Caleb E. Finch, Michael Gurven, Hillard Kaplan

ESI Publications

Poor oral health is associated with cardiovascular disease and dementia. Potential pathways include sepsis from oral bacteria, systemic inflammation, and nutritional deficiencies. However, in post-industrialized populations, links between oral health and chronic disease may be confounded because the lower socioeconomic exposome (poor diet, pollution, low physical activity) often entails insufficient dental care. We assessed tooth loss, caries, and damaged teeth, in relation to cardiovascular and brain aging among the Tsimane, a subsistence population living a relatively traditional forager-horticulturalist lifestyle with poor dental health, but minimal cardiovascular disease and dementia. Dental health was assessed by a physician in 739 participants aged …

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.

Experimental Research On Contests, Subhashish M. Chowdhury, Dan Kovenock, Anwesha Mukherjee

ESI Working Papers

Contests are situations in which agents compete by irreversibly expending costly resources in an attempt to win a prize. Due to their applications in conflict, rent-seeking, organizational incentives, sports, litigation, and political campaigns, contests are widely applied in the social sciences. In this survey we summarize some main results and recent developments of experimental studies in contest theory. We also point out their broader applications in the social sciences.

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: Vocal Systems As Embodied Capital For Mediating Within-Group Conflict, Eric Schniter, Mateo Peñaherrera-Aguirre

ESI Working Papers

Life history traits constrain investments in costly neural and somatic embodied capital, potentially shaping the evolution of primate vocal communication systems. This study integrates life history theory with the social complexity hypothesis to test a sequential pathway from longevity to social dynamics to vocal repertoire size, using updated vocal repertoire data for McComb & Semple’s (2005) set of 42 non-human primate species, alongside measures of group size and within-group conflict. We compiled data on vocal repertoire size, within-group conflict, group size, endocranial volume, and maximum longevity, analysing these via Phylogenetic Sequential Canonical Cascade Model and ancestral character reconstructions. …

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

We trace the evolution of the language of science, religion, and political economy in the centuries leading to the British Industrial Revolution. Using textual analysis of 264,443 works printed in England between 1500 and 1900, we test whether British culture manifested a belief in progress associated with science and industry. Our analysis yields three main findings. First, there was a separation in the languages of science and religion beginning in the mid-18th century. Second, volumes using language at the nexus of science and political economy became more progress-oriented during the Enlightenment. Third, volumes using industrial language—especially those at the science-political …

Testosterone Is Positively Associated With Coronary Artery Calcium In A Low Cardiovascular Disease Risk Population, Benjamin Trumble, Jacob Negrey, Stephanie V. Koebele, Randall C. Thompson, L.

ESI Publications

Background

In industrialized populations, low male testosterone is associated with higher rates of cardiovascular mortality. However, coronary risk factors like obesity impact both testosterone and cardiovascular outcomes. Here, we assess the role of endogenous testosterone on coronary artery calcium in an active subsistence population with relatively low testosterone levels, low cardiovascular risk and low coronary artery calcium scores.

Methodology

In this cross-sectional community-based study, 719 Tsimane forager-horticulturalists in the Bolivian Amazon aged 40+ years underwent computed tomography (49.8% male, mean age 57.6 years).

Results

Coronary artery calcium levels were low; 84.5% had no coronary artery calcium. Zero-inflated negative binomial models …

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, Weiwei Zheng, Jason Shachat, Daniel Houser

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 level 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, any gift is one extended to the seller. When the market institution dictates that prices are formed by offers posted …

Asymmetric Shocks In Contests: Theory And Experiment, Jian Song, Daniel Houser

ESI Publications

Under optimal tournament design, equilibrium effort is invariant to the shape of the mean-zero additive stochastic component, often referred to as a “shock” or “noise”. We report data from laboratory experiments providing the first test of this prediction. Consistent with theory, we find that average effort does not significantly differ between a negatively skewed and uniform shock distribution. In addition, we test a second theoretical prediction that, in winner tournaments, when the shock distribution is asymmetric as in our design, one should exert minimum effort whenever one's competitors are exerting above equilibrium effort. With a symmetric shock distribution as in …

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

ESI Working Papers

One of the objectives of two-sided matching mechanisms is to pair two groups of agents such that there is no incentive for pair deviation. The outcome of a match can significantly impact participants. While much of the existing research in this field addresses the matching with fixed quotas, this is not always applicable. We introduce the concept of slot stability, recognizing the potential motivation for organizations to modify their quotas after the match. We propose an algorithm designed to create stable and slot stable matches by employing flexible, endogenous quotas to address this issue.

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 …

What Did Adam Smith Mean? The Semantics Of The Opening Key Principles In The Wealth Of Nations, Bart J. Wilson, Gian Marco Farese

ESI Publications

We present a semantic and textual analysis of the first two chapters of the Wealth of Nations to elucidate the meaning of several of Adam Smith’s key ideas. Using the methodology of the Natural Semantic Metalanguage, we produce semantic explications of some of Adam Smith’s fundamental principles of economics phrased in simple and cross-translatable words. The extracts from the original text function as textual evidence and conceptual reference for the explications we present. We demonstrate that: (i) by reducing the principles as conceived by Smith to their core meanings, it is possible to resolve some interpretive ambiguities for general readers …

Metapopulation Dynamics Of Sars-Cov-2 Transmission In A Small-Scale Amazonian Society, Thomas Kraft, Edmond Seabright, Sarah Alami, Samuel M. Jenness, Paul L.

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 …

Revisit The Moving Average Technical Trading Rule For The Nasdaq Composite Index, Louie Ren, Peter Ren, Jeffrey Yi-Lin Forrest

Pennsylvania Economic Review

We check the regression model assumptions via residual analysis using one dummy variable for Buy and Sell Days. Since the returns of the NASDAQ composite index is not stationary, it is inappropriate to use the Student T-test on Buy and Sell Days to analyze the efficiency of the market via moving average technical trading rules. As such, the Buy-Sell Days from the moving average trading rules have no predictability on daily NASDAQ index returns. This refutes the results of at least two studies on the NASDAQ Composite Index.

Fiscal Decentralization And Economic Performance In Selected Developing Federal Econom, Samuel Onyeka Okonkwo, Walter Okwudili Ugwuoke Phd

Bullion

Extant literatures on fiscal decentralization in most developing countries show more concerns on revenue allocation principle/sharing. Contrary to extant studies, this paper undertakes analysis of fiscal decentralization and economic performance in five emerging federal economies. The curiosity is to ascertain if poor economic performance in most emerging economies could be attributed to ill - structured fiscal decentralization. This objective was addressed using Panel Vector Autoregressive technique and impulse response function. The results showed that all the measures of fiscal decentralization such as revenue measure denoted as (FDC1), spending measure denoted as (FDC2) and revenue — spending measure or Simultaneity measure …

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 …
