Coronary Atherosclerosis In Indigenous South American Tsimane: A Cross-Sectional Cohort Study, Hillard Kaplan, Randall C. Thompson, Benjamin C. Trumble, L. Samuel Wann, Adel H. Allam, Bret Beheim, Bruno Frohlich, M. Linda Sutherland, James D. Sutherland, Jonathan Stieglitz, Daniel Eid Rodriguez, David E. Michalik, Chris J. Rowan, Guido P. Lombardi, Ram Bedi, Angela R. Garcia, James K. Min, Jagat Narula, Caleb E. Finch, Michael Gurven, Gregory S. Thomas

ESI Publications

Background—Conventional coronary artery disease risk factors might potentially explain at least 90% of the attributable risk of coronary artery disease. To better understand the association between the pre-industrial lifestyle and low prevalence of coronary artery disease risk factors, we examined the Tsimane, a Bolivian population living a subsistence lifestyle of hunting, gathering, fishing, and farming with few cardiovascular risk factors, but high infectious inflammatory burden.

Methods—We did a cross-sectional cohort study including all individuals who self-identified as Tsimane and who were aged 40 years or older. Coronary atherosclerosis was assessed by coronary artery calcium (CAC) scoring done with …

Smile, Dictator, You’Re On Camera, Joy A. Buchanan, Matthew K. Mcmahon, Matthew Simpson, Bart J. Wilson

ESI Publications

We investigate the degree to which people in a shopping mall express other-regarding behavior in the dictator game. Whereas many studies have attempted to increase the social distance between the dictator and experimenter and between the dictator and dictatee, we attempt to minimize that social distance between random strangers by video recording the decisions with the permission of the dictators to display their image on the Internet. Offers made by dictators are high relative to other experiments and a nontrivial number give the entire experimental windfall away, however a nontrivial number of people keep everything as well.

The Tsimane Health And Life History Project: Integrating Anthropology And Biomedicine, Michael Gurven, Jonathan Stieglitz, Benjamin C. Trumble, Aaron D. Blackwell, Bret Beheim, Helen Davis, Hillard Kaplan, Paul L. Hooper

ESI Publications

The Tsimane Health and Life History Project, an integrated bio-behavioral study of the human life course, is designed to test competing hypotheses of human life-history evolution. One aim is to understand the bidirectional connections between life history and social behavior in a highfertility, kin-based context lacking amenities of modern urban life (e.g. sanitation, banks, electricity). Another aim is to understand how a high pathogen burden influences health and well-being during development and adulthood. A third aim addresses how modernization shapes human life histories and sociality. Here we outline the project’s goals, history, and main findings since its inception in 2002. …

A Study Of The Triggers Of Conflict And Emotional Reactions, Michael Caldera, Michael T. Mcbride, Matthew W. Mccarter, Roman M. Sheremeta

ESI Publications

We study three triggers of conflict and explore their resultant emotional reactions in a laboratory experiment. Economists suggest that the primary trigger of conflict is monetary incentives. Social psychologists suggest that conflicts are often triggered by fear. Finally, evolutionary biologists suggest that a third trigger is uncertainty about an opponent’s desire to cause harm. Consistent with the predictions from economics, social psychology, and evolutionary biology, we find that conflict originates from all three triggers. The three triggers differently impact the frequency of conflict, but not the intensity. Also, we find that the frequency and intensity of conflict decrease positive emotions …

Do Farm Subsidies Affect Crop Diversification?, Chadwick O'Neal

Georgia College Student Research Events

The United States spends $20 billion each year on farm subsidies. Farmers face increased risk and income variation when their crop portfolio is less diversified. It’s possible for farm subsidies to decrease diversification if they are focused on specific crops. Utilizing state level subsidy and agricultural data from the Environmental Working Group, I used econometric analysis to estimate the effect of farm subsidies on crop diversification. I used the number of acres planted from the 15 top most subsidized and grown crops in the United States to derive my dependent variable, the Herfindahl-Hirschman index (HHI). The HHI is a market …

Trends In U.S. Tea Imports: 1991-2015, Evan Kennedy

Honors Theses

Tea is the second most popular beverage in the world, and over the past two decades it has experienced a newfound popularity in the United States. Over this time period, ready-to-drink and loose-leaf tea has increased in popularity, whereas tea bags and instant tea declined in popularity. Since the United States produces almost no tea itself, an increase in consumption requires increased imports. Therefore, this paper examines U.S. import trends as a means to begin an examination of consumption. Ten countries (Argentina, Canada, China, Germany, India, Japan, Kenya, Sri Lanka, the United Kingdom, and Vietnam) provide approximately 80% of the …

Emotional Calibration Of Self-Control, Joaquín Gómez-Miñambres, Eric Schniter

ESI Publications

We study a dynamic model of self-control where previous decisions have influence on subsequent decision making. In our model effort and guilt are negative emotions produced by previous decisions to either resist or yield to temptation, respectively. These emotions calibrate an individual's self-control, in turn affecting future decisions. Our model explains non-stationary consumption paths characterized by compensatory indulgence and restraint, why under some circumstances the amplitude of this switching pattern increases with foresight, and how unavoidable options that might show up on one's menu influence choices, consequent emotions, consumption paths, and preferences for commitment. We discuss the implications of self-control …

Profitable Horizontal Mergers Without Efficiencies Can Increase Consumer Surplus, Charles J. Thomas

ESI Working Papers

In a simple model I show consumer surplus can increase after competing sellers consummate a profitable merger that generates no cost savings. This finding contrasts sharply with the conventional wisdom that horizontal mergers without efficiencies must enhance sellers’ market power to be profitable, thereby harming buyers. The model fits industries in which individual buyers conduct distinct procurement contests for which sellers incur costs to participate, say to assess their product’s fit with the buyer’s preferences. Mergers benefit buyers by inducing stronger contest-level entry, echoing common claims from merging parties that their merger is beneficial because it creates a stronger competitor.

The Ideological Roots Of Institutional Change, Murat Iyigun, Jared Rubin

ESI Working Papers

Why do some societies fail to adopt more efficient institutions in response to changing economic conditions? And why do such conditions sometimes generate ideological backlashes and at other times lead to transformative sociopolitical movements? We propose an explanation that highlights the interplay--or lack thereof--between new technologies, ideologies, and institutions. When new technologies emerge, uncertainty results from a lack of understanding how the technology will fit with prevailing ideologies and institutions. This uncertainty discourages investment in institutions and the cultural capital necessary to take advantage of new technologies. Accordingly, increased uncertainty during times of rapid technological change may generate an ideological …

The Economic Legacies Of Lingering Colonialism: A Case Study In Identity And Multiculturalism In Northern Morocco And The Spanish Enclaves, Jeremy Vale

Independent Study Project (ISP) Collection

Founded in ancient times, the twin Spanish cities of Ceuta and Melilla combined comprise just 11.8 square miles and have fewer than 200,000 inhabitants. Despite their rather insignificant sizes, they are important because they serve as the only land borders between the European Union and the African continent, generating a host of complicated questions. This research explores the role of smuggling as a form of micro-economy and identity. Through interviews of Moroccans with ties to smuggling as well as interviews with residents of Ceuta, this case study begins to examine the role smuggling plays in the debates about the sovereignty …

Foreign Aid Allocation And Impact In Latin America And The Caribbean (Lac): A Cross-Country Analysis Of Foreign Aid Impact On Gdp Per Capita And Life Expectancy, Ancito Etienne

Undergraduate Theses and Capstone Projects

This research paper is an empirical study of the impact of official development assistance and official aid received, [henceforth, to be referred to as “foreign aid”], on life expectancy and GDP per capita in Latin America and the Caribbean. I used a panel dataset of 19 countries dated from 1996 to 2014 to perform two distinctive regressions using the OLS method. In addition, an exploration of the impact of GDP per capita on life expectancy was conducted to determine whether there was a cause and effect phenomenon; that is, testing whether an impact of foreign aid on GDP per capita …

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

ESI Working Papers

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 Habsburg and Ottoman/Russian border despite being located seven kilometers apart. Russian and Ottoman Öscal institutions were more rapacious than Habsburg institutions, which may have eroded trust of outsiders (relative to co-villagers). Our design permits us to rigorously test this conjecture, and more generally, whether historically institutionalized cultural norms are transmitted intergenerationally. We Önd that participants on the Ottoman/Russian side are indeed less likely to trust outsiders but more likely to trust co-villagers.

Horticultural Activity Predicts Later Localized Limb Status In A Contemporary Pre-Industrial Population, Jonathan Stieglitz, Benjamin C. Trumble, Hillard Kaplan, Michael Gurven

ESI Publications

Objectives—Modern humans may have gracile skeletons due to low physical activity levels and mechanical loading. Tests using prehistoric skeletons are limited by the inability to assess behaviour directly, while modern industrialized societies possess few socio-ecological features typical of human evolutionary history. Among Tsimane forager-horticulturalists, we test whether greater activity levels and, thus, increased loading earlier in life are associated with greater later-life bone status and diminished age-related bone loss.

Materials and Methods—We used quantitative ultrasonography to assess radial and tibial status among adults aged 20+ years (mean±SD age=49±15; 52% female). We conducted systematic behavioural observations to assess earlier-life …

Deception And Reception: The Behavior Of Information Providers And Users, Roman M. Sheremeta, Timothy W. Shields

ESI Working Papers

We investigate the behavior of information providers (underwriters) and users (investors) in a controlled laboratory experiment where underwriters have incentives to deceive and investors have incentives to avoid deception. Participants play simultaneously as underwriters and investors in one-shot information transmission games. The results of our experiment show a significant proportion of both deceptive and non-deceptive underwriters. Despite the presence of deceptive underwriters, investors are receptive to underwriters’ reports, gleaning information content, albeit overly optimistic. Within our sample, deception by underwriters and reception by investors are the most profitable strategies. Moreover, participants who send deceptive reports to investors, but at the …

Monitoring Institutions In Indefinitely Repeated Games, Gabriele Camera, Marco Casari

ESI Working Papers

Does monitoring past conduct facilitate intertemporal cooperation? We designed an experiment characterized by strategic uncertainty and multiple equilibria where coordinating on the efficient outcome is a challenge. Participants, interacting anonymously in a group, could pay a cost either to obtain information about their counterparts, or to create a freely available public record of individual conduct. Both monitoring institutions were actively employed. However, groups were unable to attain higher levels of cooperation compared to a treatment without monitoring. Information about past conduct alone thus appears to be ineffective in overcoming coordination challenges.

Targeted Campaign Competition, Loyal Voters, And Supermajorities, Pierre C. Boyer, Kai A. Konrad, Brian Roberson

ESI Working Papers

We consider campaign competition in which candidates compete for votes among a continuum of voters by engaging in persuasive efforts that are targetable. Each individual voter is persuaded by campaign effort and votes for the candidate who targets more persuasive effort to this voter. Each candidate chooses a level of total campaign effort and allocates their effort among the set of voters. We completely characterize equilibrium for the majoritarian objective game and compare that to the vote-share maximizing game. If the candidates are symmetric ex ante, both types of electoral competition dissipate the rents from once in expectation. However, the …

Rulers, Religion, And Riches: Why The West Got Rich And The Middle East Did Not, Jared Rubin

Economics Faculty Books and Book Chapters

For centuries following the spread of Islam, the Middle East was far ahead of Europe. Yet, the modern economy was born in Europe. Why was it not born in the Middle East? In this book Jared Rubin examines the role that Islam played in this reversal of fortunes. It argues that the religion itself is not to blame; the importance of religious legitimacy in Middle Eastern politics was the primary culprit. Muslim religious authorities were given an important seat at the political bargaining table, which they used to block important advancements such as the printing press and lending at interest. …

The Paradox Of Power: Principal-Agent Problems And Fiscal Capacity In Absolutist Regimes, Debin Ma, Jared Rubin

ESI Working Papers

Tax extraction in Qing China was low relative to Western Europe. It is not obvious why: China was much more absolutist and had stronger rights over property and people. Why did the Chinese not convert their absolute power into revenue? We propose a model, supported by historical evidence, which suggests that i) the center could not ask its tax collecting agents to levy high taxes because it would incentivize agents to overtax the peasantry; ii) the center could not pay agents high wages in return for high taxes because the center had no mechanism to commit to refrain from confiscating …

Coordination When There Are Restricted And Unrestricted Options, Shaun P. Hargreaves Heap, David Rojo Arjona, Robert Sugden

Economics Faculty Articles and Research

One might expect that, in pure coordination games, coordination would become less frequent as the number of options increases. Contrary to this expectation, we report an experiment which found more frequent coordination when the option set was unrestricted than when it was restricted. To try to explain this result, we develop a method for eliciting the general rules that subjects use to identify salient options in restricted and unrestricted sets. We find that each such rule, if used by all subjects, would generate greater coordination in restricted sets. However, subjects tend to apply different rules to restricted and unrestricted sets.

Human Grooming In Comparative Perspective: People In Six Small-Scale Societies Groom Less But Socialize Just As Much As Expected For A Typical Primate, Adrian V. Jaeggi, Karen Kramer, Raymond Hames, Evan J. Kiely, Cristina Gomes, Hillard Kaplan, Michael Gurven

ESI Publications

Objectives—Grooming has important utilitarian and social functions in primates but little is known about grooming and its functional analogues in traditional human societies. We compare human grooming to typical primate patterns to test its hygienic and social functions.

Materials and Methods—Bayesian phylogenetic analyses were used to derive expected human grooming time given the potential associations between grooming, group size, body size, terrestriality, and several climatic variables across 69 primate species. This was compared against observed times dedicated to grooming, other hygienic behavior and conversation among the Maya, Pumé, Sanöma, Tsimane’, Yanomamö, and Ye’kwana (mean number of behavioral scans …

Deliberation Favours Social Efficiency By Making People Disregard Their Relative Shares: Evidence From Usa And India, Valerie Capraro, Brice Corgnet, Antonio M. Espín, Roberto Hernán-González

ESI Publications

Groups make decisions on both the production and the distribution of resources. These decisions typically involve a tension between increasing the total level of group resources (i.e. social efficiency) and distributing these resources among group members (i.e. individuals’ relative shares). This is the case because the redistribution process may destroy part of the resources, thus resulting in socially inefficient allocations. Here we apply a dual-process approach to understand the cognitive underpinnings of this fundamental tension. We conducted a set of experiments to examine the extent to which different allocation decisions respond to intuition or deliberation. In a newly developed approach, …

Investing In The Presence Of Massive Flows, Terence C. Burnham, Harry Gakidis, Jeffrey Wurgler

ESI Working Papers

Approximately $10 trillion is benchmarked to Morgan Stanley Capital International’s Developed, Emerging, Frontier, and standalone market indexes. Reclassifications from one index to another require thousands of investors to decide how to react. We study a comprehensive sample of past reclassifications to guide this decision. Reclassified markets’ prices substantially overshoot between the announcement and effective dates—prices fall when a market moves from an index with more benchmarked ownership to one with less, such from Emerging to Frontier, and vice-versa—but revert within a year. We identify alpha-maximizing responses to reclassifications for both tightly benchmarked and more flexible investors.

Fdi And Income Inequality In Latin America, Terese Coulon

Empirical Economic Bulletin, An Undergraduate Journal

The main purpose of this paper is to determine the relationship between FDI and income inequality in Latin America after Operation Condor. This study uses economic panel data from seven different Latin American countries over a sixteen year time period. This study takes place from 1982 to 1997. Other variables have been included in this study to achieve the most accurate results possible. The results from this study show that FDI is significant to income inequality at the 5% significance level in Latin America during this time period. Also, the results indicate that FDI has a positive effect on income …

Are Education And Economic Growth Related? Some Evidence From The States, R. W. Hafer

Center for Applied Economics

It seems common sense that the more educated someone is, the greater the chances that they will have relatively higher incomes. Indeed, on average someone with a college degree is more likely will have a higher lifetime stream of earnings than someone who only graduates from high school. Does this same relationship hold at the state level? Are states with better education outcomes also the states that tend to grow faster? More specifically, what does the evidence on Missouri’s educational achievement predict for the state’s economic future?

We investigate whether differences in economic growth across states are in part explainable …

Income Inequality In Latin America And The Caribbean: Inefficient Labor Markets And Remnants Of Racism, Vivian Tejada

Empirical Economic Bulletin, An Undergraduate Journal

This paper aims to explore the key reasons as to why income inequality in Latin America is so vast. The study will investigate the various manners in which labor markets operate throughout Latin America and attempt to draw a connection between labor market inefficiency and income inequality keeping in mind the regions tumulus history with racism. Factors considered in this assessment are rate of income levels, unemployment, GDP p/capita, educational attainment, and age of labor force. The factors are accounted for in a regression model to examine the level of influence labor markets and race have on income inequality.

Effects Of Drought Conditions On Agricultural Productivity In Central And Western Tennessee, Sean Erwin

Empirical Economic Bulletin, An Undergraduate Journal

This paper analyzes the relationship between agricultural productivity of farms in drought conditions. The variables used in this research include fertilizer expense, precipitation totals, and average temperature. The model integrates all of the mentioned variables and finds the connection between the land value of farms and the variables. The outcomes show that both fertilizer expense and precipitation have negative relationships to land values for farms, while average temperature has a positive relationship.

Fiscal Policy And Its Effects On Economic Growth, Jordan J. Smith

Empirical Economic Bulletin, An Undergraduate Journal

This paper investigates the impact of fiscal policy on economic growth during the time horizons of 1985, 1998, and 2014. Using cross country data from a minimum of 37 countries, it is found that international trade taxes share a partial correlation with economic growth. The magnitude of this relationship is found to be positive during all time horizons, and is diminishing over time. Estimates from 2014 suggest that a 10 percentage point increase in a country’s international trade tax will grant that country a .6% increase to their economic growth rate.
