Background: Atrial fibrillation is the most common arrhythmia in post-industrialized populations. Older age, hypertension, obesity, chronic inflammation, and diabetes are significant atrial fibrillation risk factors, suggesting that modern urban environments may promote atrial fibrillation.
Objective: Here we assess atrial fibrillation prevalence and incidence among tropical horticulturalists of the Bolivian Amazon with high levels of physical activity, a lean diet, and minimal coronary atherosclerosis, but also high infectious disease burden and associated inflammation.
Methods: Between 2005–2019, 1314 Tsimane aged 40–94 years (52% female) and 534 Moseten Amerindians aged 40–89 years (50% female) underwent resting 12-lead electrocardiograms to assess ...
Negative Shocks Predict Change In Cognitive Function And Preferences: Assessing The Negative Affect And Stress Hypothesis, 2021 Universidad Nacional de Colombia
Negative Shocks Predict Change In Cognitive Function And Preferences: Assessing The Negative Affect And Stress Hypothesis, Francesco Bogliacino, Cristiano Codagnone, Felipe Montealegre, Frans Folkvord, Camilo Gómez, Rafael Charris, Giovanni Liva, Francisco Lupiáñez-Villanueva, Giuseppe A. Veltri
In the context of the current COVID-19 pandemic, households throughout the world have to cope with negative shocks. Previous research has shown that negative shocks impair cognitive function and change risk, time and social preferences. In this study, we analyze the results of a longitudinal multi-country survey conducted in Italy (N = 1652), Spain (N = 1660) and the United Kingdom (N = 1578). We measure cognitive function using the Cognitive Reflection Test and preferences traits (risk, time and social preferences) using an experimentally validated set of questions to assess the differences between people exposed to a shock compared to the rest of ...

A Class Of N-Player Colonel Blotto Games With Multidimensional Private Information, 2021 University of Zurich
A Class Of N-Player Colonel Blotto Games With Multidimensional Private Information, Christian Ewerhart, Dan Kovenock
ESI Working Papers
In this paper, we study N-player Colonel Blotto games with incomplete information about battlefield valuations. Such games arise in job markets, research and development, electoral competition, security analysis, and conflict resolution. For M ≥ N + 1 battlefields, we identify a Bayes-Nash equilibrium in which the resource allocation to a given battlefield is strictly monotone in the valuation of that battlefield. We also explore extensions such as heterogeneous budgets, the case M ≤ N, full-support type distributions, and network games.
Economics Students: Self-Selected In Preferences And Indoctrinated In Beliefs, 2021 Chapman University
Economics Students: Self-Selected In Preferences And Indoctrinated In Beliefs, Antonio M. Espín, Manuel Correa, Alberto Ruiz-Villaverde
ESI Working Papers
There is much debate as to why economics students display more self-interested behavior than other students: whether homo economicus self-select into economics or students are instead “indoctrinated” by economics learning, and whether these effects impact on preferences or beliefs about others’ behavior. Using a classroom survey (n>500) with novel behavioral questions we show that, compared to students in other majors, econ students report being: (i) more self-interested (in particular, less compassionate or averse to advantageous inequality) already in the first year and the difference remains among more senior students; (ii) more likely to think that people will be unwilling ...
Institutions And Opportunistic Behavior: Experimental Evidence, 2021 Universidad Carlos III de Madrid
Institutions And Opportunistic Behavior: Experimental Evidence, Antonio Cabrales, Irma Clots-Figueras, Roberto Hernán-González, Praveen Kujal
ESI Working Papers
Risk mitigating institutions have long been used by societies to protect against opportunistic behavior. We know little about how they are demanded, who demands them or how they impact subsequent behavior. To study these questions, we run a large-scale online experiment where insurance can be purchased to safeguard against opportunistic behavior. We compare two different selection mechanisms for risk mitigation, the individual and the collective (voting). We find that, whether individual or collective, there is demand for riskmitigating institutions amongst high-opportunism individuals, while low-opportunism individuals demand lesser levels of insurance. However, high-opportunism individuals strategically demand lower insurance institutions when they ...
In-Group Versus Out-Group Preferences In Intergroup Conflict: An Experiment, 2021 University of Bath
In-Group Versus Out-Group Preferences In Intergroup Conflict: An Experiment, Subhashish M. Chowdhury, Anwesha Mukherjee, Roman M. Sheremeta
ESI Working Papers
Individuals participating in a group conflict have different preferences, e.g., maximizing their own payoff, maximizing the group’s payoff, or defeating the rivals. When such preferences are present simultaneously, it is difficult to distinctly identify the impact of those preferences on conflict. In order to separate in-group and out-group preferences, we conduct an experiment in which human in-group or out-group players are removed while keeping the game strategically similar. Our design allows us to study (i) how effort in a group conflict vary due to in-group and out-group preferences, and (ii) how the impact of these preferences vary when ...
Identifying Bedrest Using Waist-Worn Triaxial Accelerometers In Preschool Children, 2021 Chapman University
Identifying Bedrest Using Waist-Worn Triaxial Accelerometers In Preschool Children, J. Dustin Tracy, Thomas Donnelly, Evan C. Sommer, William J. Heerman, Shari L. Barkin, Maciej S. Buchowski
To adapt and validate a previously developed decision tree for youth to identify bedrest for use in preschool children.
Parents of healthy preschool (3-6-year-old) children (n = 610; 294 males) were asked to help them to wear an accelerometer for 7 to 10 days and 24 hours/day on their waist. Children with ≥3 nights of valid recordings were randomly allocated to the development (n = 200) and validation (n = 200) groups. Wear periods from accelerometer recordings were identified minute-by-minute as bedrest or wake using visual identification by two independent raters. To automate visual identification, chosen decision tree (DT) parameters ...
Gambling With Debt: The English Premier League, 2021 University of Derby
Gambling With Debt: The English Premier League, Edward Robinson
Undergraduate Economic Review
This paper aims to investigate the impact of debt on financial performance in the English Premier League from the 2000/01 season to the 2017/18 season. Panel model estimations concluded debt has a significant inverse relationship with financial performance. This relationship may potentially be stronger in larger clubs and could be present through human capital investment’s significant direct relationship with financial performance. This further emphasised usages of intangible assets as a player human capital investment indicator, rather than using wage costs like previous studies. Furthermore, filling a gap regarding how capital structures may be used to impact financial ...
Do Truth-Telling Oaths Improve Honesty In Crowd-Working?, 2021 Paris School of Economics
Do Truth-Telling Oaths Improve Honesty In Crowd-Working?, Nicolas Jacquemet, Alexander G. James, Stéphane Luchini, James J. Murphy, Jason F. Shogren
This study explores whether an oath to honesty can reduce both shirking and lying among crowd-sourced internet workers. Using a classic coin-flip experiment, we first confirm that a substantial majority of Mechanical Turk workers both shirk and lie when reporting the number of heads flipped. We then demonstrate that lying can be reduced by first asking each worker to swear voluntarily on his or her honor to tell the truth in subsequent economic decisions. Even in this online, purely anonymous environment, the oath significantly reduced the percent of subjects telling “big” lies (by roughly 27%), but did not affect shirking ...
Monetization Of Fiscal Deficits And Covid-19: A Primer, 2021 Financial Stability Institute, Bank for International Settlements
Monetization Of Fiscal Deficits And Covid-19: A Primer, Aidan Lawson, Greg Feldberg
The Journal of Financial Crises
Monetization—also known as “money-financed fiscal programs” or “money-printing”—occurs when a government finances itself by issuing currency or other non-interest-bearing liabilities, such as bank reserves. It poses real risks—potentially excessive inflation and encroachment on central-bank independence—and some paint it as a relic of a bygone era. The onset of the COVID-19 crisis, however, forced governments to spend heavily to combat the considerable economic and public health impacts. As government deficits climbed, monetization re-entered the conversation as a way to avoid the massive debt burdens that some nations may face. This paper describes how monetization works, provides key ...
Will Seasonality Patterns For Beef Export Sales And Commitments Hold In 2021?, 2021 University of Nebraska - Lincoln
Will Seasonality Patterns For Beef Export Sales And Commitments Hold In 2021?, Elliott James Dennis
Extension Farm and Ranch Management
First two paragraphs:
Trade occurs when price differences between the two locations are large enough after accounting for transportation cost, exchange rates, tariffs, etc. Exports vary throughout the year since prices reflect current and future supply and demand situations. Seasonality in cattle production, meat demand, and market disruptions are some examples of why wholesale beef prices increase and decrease within a year.
The inability to market cattle in the second quarter of 2020 and increased demand for retail beef products due to government gathering restrictions in restaurants caused wholesale beef prices to rise to historical levels. Beef wholesalers can choose ...
Ways Forward In Energy Markets And The Environment, 2021 The University of Akron
Ways Forward In Energy Markets And The Environment, Jacob Nelson
Williams Honors College, Honors Research Projects
Renewable energy sources have come to the forefront of energy production policy over the last twenty years. Studies of external and direct costs of both renewable and nonrenewable energy sources have contributed to growing understandings of ways in which these energy sources can be compared in a monetary context. Using data from the U.S. Energy Information Administration (EIA) alongside international data from the International Renewable Energy Agency (IRENA) among other sources, we have developed forecasts for the future costs, both direct and social, of each energy source as well as a difference-in-difference experiment to determine potential effects of state-level ...

Quantifying The Impact Of Remapping Floodplains On Residential Property Values In Snohomish County, Washington: A Hedonic Approach, 2021 Central Washington University
Quantifying The Impact Of Remapping Floodplains On Residential Property Values In Snohomish County, Washington: A Hedonic Approach, Carson Joseph Risner
All Master's Theses
Flood events are the most common and costly natural disasters. The Federal Emergency Management Agency (FEMA) quantifies flood risks in the form of Flood Insurance Rate Maps (FIRMS). These FIRMS delineate flood risks and are used to set flood insurance premiums. Changes in land use, the augmentation of the natural environment, is threatening the validity of the Nation’s FIRMS. Therefore, Congress has approved remapping programs to update these FIRMs ensuring that current flood risks are known. This remapping presents another issue, specifically for properties that are remapped into a flood zone. Current literature suggests that properties within flood zones ...
Fair Play: Notes On The Algorithmic Soccer Referee, 2021 University of Pittsburgh School of Law
Fair Play: Notes On The Algorithmic Soccer Referee, Michael J. Madison
The soccer referee stands in for a judge. Soccer’s Video Assistant Referee (“VAR”) system stands in for algorithms that augment human deciders. Fair play stands in for justice. They are combined and set in a polycentric system of governance, with implications for designing, administering, and assessing human-machine combinations.
Race, Dignity, And Commerce, 2021 University of Pittsburgh School of Law
Race, Dignity, And Commerce, Lu-In Wang
This Essay was written at the invitation of the Journal of Law and Commerce to contribute a piece on racism and commerce—an invitation that was welcome and well timed. It arrived as renewed attention was focused on racialized policing following the killing of George Floyd and in the midst of the worsening pandemic that highlighted unrelenting racial, social, and economic inequities in our society.
The connections between racism and commerce are potentially numerous, but the relationship between discriminatory policing and commerce might not be apparent. This Essay links them through the concept of dignity. Legal scholar John Felipe Acevedo ...
Benefit-Cost Analysis Of Covid-19 Policy Intervention At The State And National Level, 2021 Chapman University
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 ...
Culture, Institutions & The Long Divergence, 2021 New York University
Culture, Institutions & The Long Divergence, Alberto Bisin, Jared Rubin, Avner Seror, Thierry Verdier
ESI Working Papers
Recent theories of the Long Divergence between Middle Eastern and Western European economies focus on Middle Eastern (over-)reliance on religious legitimacy, use of slave soldiers, and persistence of restrictive proscriptions of religious (Islamic) law. These theories take as exogenous the cultural values that complement the prevailing institutions. As a result, they miss the role of cultural values in either supporting the persistence of or inducing change in the economic and institutional environment. In this paper, we address these issues by modeling the joint evolution of institutions and culture. In doing so, we place the various hypotheses of economic divergence ...
A Simple Measure Of Economic Complexity, 2021 Chapman University
A Simple Measure Of Economic Complexity, Sabiou M. Inoua
ESI Working Papers
The conventional view on economic development simplifies a country’s production to one aggregate variable, GDP. Yet product diversification matters for economic development, as recent, data-driven, “economic complexity” research suggests. A country’s product diversity reflects the country’s diversity of productive knowhow, or “capabilities”. Researchers derive from algorithms (inspired by network theory) measures of the number of capabilities in an economy, notably the Economic Complexity Index (ECI), argued to predict economic growth better than traditional variables such as human capital; and the country Fitness index, argued to remedy limitations of the ECI. This paper offers an alternative economic complexity ...
