Low Mineral Density Of A Weight-Bearing Bone Among Adult Women In A High Fertility Population, Jonathan Stieglitz, Bret Beheim, Benjamin C. Trumble, Felicia C. Madimenos, Hillard Kaplan, Michael Gurven

ESI Publications

Evolutionary theories of aging posit that greater reproductive effort causes somatic decline given a fundamental trade-off between investing energy in reproduction and repair. Few studies in high fertility human populations support this hypothesis, and problems of phenotypic correlation can obscure the expected trade-off between reproduction and somatic condition. This cross-sectional study investigates whether greater reproductive effort is associated with reduced calcaneal bone mineral density (BMD) among female Tsimane forager-farmers of lowland Bolivia. We also investigate whether female Tsimane BMD values are lower than sex- and age-matched US reference values, despite the fact that Tsimane engage in higher physical activity levels …

Financial Literacy And Financial Inclusion Of Women In Rural Rajasthan, Emily Levi-D'Ancona

Independent Study Project (ISP) Collection

Financial inclusion is an important step in development, as access to finances can help the poor build money and lift themselves out of poverty. In many parts of the developing world, and especially in India, microfinance is seen as a new approach to fighting poverty by bringing financial services, including low-interest loans, to the poor so that they can afford to start a business or invest and eventually gain self-sufficiency – in other words, a method of financial inclusion for the poor. However, microfinance in India cannot sufficiently reach the poor populations, especially those in rural India, and many of …

The Natural Resource Curse In Sub-Saharan Africa: Transparency And International Initiatives, Meaza Zerihun Demissie

Dissertations

The Sub-Saharan Africa (SSA) region has become a classic case of the resource-curse phenomenon characterized by the abundance of natural resources, low economic development, and misuse of natural resources. Economic-development experts debate ways to overcome or avoid the resource curse to advance SSA countries into developed countries. Only one natural resource-rich country in the region, Botswana, has succeeded in becoming an upper middle-income country using its natural resources, making the possibility of replication of this achievement difficult. The literature aligns in the belief that the economic and political well-being of resource-rich nations depends highly on the actors involved. National and …

Top Of The Order: Modeling The Optimal Locations Of Minor League Baseball Teams, W. Coleman Conley

Undergraduate Economic Review

Over the last twenty-five years, minor league baseball franchises have defined firm mobility. Revisiting the work of Michael C. Davis (2006), I construct a logistic regression model to predict which cities house minor league baseball teams. Six variables are tested for inclusion in the model, including population, income level, the number of major-league professional sports teams in a city, five-year population change, and distance from the closest professional team. Based on the model's predicted probabilities, cities are ranked in order of highest probability of having a team at each of the different levels from Class A to Class AAA.

Should You Do A Doctorate? The Changing Returns To Postgraduate Qualifications, Sven Hoeling, Lewis Gudgeon, Felix Hagemeister

Undergraduate Economic Review

Higher education in the UK has experienced radical change over the last two decades. The change has been driven by a number of factors, not least New Labour’s policy to send 50% of school leavers to university. The increased supply of graduates has weakened a first degree’s ability to function as a signal to employers, resulting in many individuals pursuing postgraduate study to make themselves more competitive. This paper aims to show the changing returns to Bachelor, Master and Doctoral degrees for the period 1997 to 2013 and recognises the increasing importance of Ph.D. graduates in the upcoming years.

Leadership In An Egalitarian Society, Christopher Von Rueden, Michael Gurven, Hillard Kaplan, Jonathan Stieglitz

ESI Publications

Leadership is instrumental to resolution of collective action dilemmas, particularly in large, heterogeneous groups. Less is known about the characteristics or effectiveness of leadership in small-scale, homogeneous, and relatively egalitarian societies, in which humans have spent most of our existence. Among Tsimane’ forager-horticulturalists of Bolivia, we (1) assess traits of elected leaders under experimental and naturalistic conditions and (2) test whether leaders impact collective action outcomes. We find that elected leaders are physically strong and have more kin and other exchange partners. Their ranks on physical dominance, kin support, and trustworthiness predict how well their groups perform, but only where …

Political Influence Associates With Cortisol And Health Among Egalitarian Forager-Farmers, Christopher Von Rueden, Benjamin C. Trumble, Melissa Emery Thompson, Jonathan Stieglitz, Paul L. Hooper, Aaron D. Blackwell, Hillard Kaplan, Michael Gurven

ESI Publications

Background and objectives: Low social status increases risk of disease due, in part, to the psychosocial stress that accompanies feeling subordinate or poor. Previous studies report that chronic stress and chronically elevated cortisol can impair cardiovascular and immune function. We test whether lower status is more benign in small-scale, relatively egalitarian societies, where leaders lack coercive authority and there is minimal material wealth to contest.

Methodology: Among Tsimane’ forager-horticulturalists of lowland Bolivia, we compare informal political influence among men with urinary cortisol, immune activation (innate and acquired), and morbidity as assessed during routine medical exams.

Results: After …

Cost Share Adjustment Processes For Cooperative Group Decisions About Shared Goods: A Design Approach, Edna T. Loehman, Richard Kiser, Stephen Rassenti

Economics Faculty Articles and Research

For group decision about shared goods, the nature of the shared good and how its cost is to be shared among group members must be determined. Complexity arises from heterogeneity in preferences and endowments and nonlinear cost. To facilitate group decision, this paper proposes special type of group decision support system, a cost share adjustment process (CSAP), in which cost shares are adjusted iteratively via algorithmic rules until unanimity is reached, ideally producing a socially optimal, cost feasible, and fair outcome. In contrast to public good literature, our designs apply for situations of nonlinear cost, with economies of scale and …

Clean Cooking: The Value Of Clean Cookstoves In Ethiopia, Shannon H. Kooser

Journal of Environmental and Resource Economics at Colby

This project investigates how demographic differences affect the way people value clean cookstoves in Ethiopia. Previous research indicates that traditional cooking methods are harmful to human health as well as the environment, as people need to cut down trees or collect other biomass sources for fuel. However, clean stoves can solve both these environmental and health problems, as well as provide a sustainable method for cooking and heating in developing countries. Using choice survey data, this study examines Ethiopian households’ valuations of different characteristics of stoves, including durability, fuel reduction, smoke reduction and the amount of time they may save …

Genomic Correlates Of Atherosclerosis In Ancient Humans, Albert Zink, L. Samuel Wann, Randall C. Thompson, Andreas Keller, Frank Maixner, Adel H. Allam, Caleb E. Finch, Bruno Frohlich, Hillard Kaplan, Guido P. Lombardi, M. Linda Sutherland, James D. Sutherland, Lucia Watson, Samantha L. Cox, Michael I. Miyamoto, Jagat Narula, Alexandre F. R. Stewart, Gregory S. Thomas, Johannes Krause

ESI Publications

Paleogenetics offers a unique opportunity to study human evolution, population dynamics, and disease evolution in situ. Although histologic and computed x-ray tomographic investigations of ancient mummies have clearly shown that atherosclerosis has been present in humans for more than 5,000 years, limited data are available on the presence of genetic predisposition for cardiovascular disease in ancient human populations. In a previous whole-genome study of the Tyrolean Iceman, a 5,300-year-old glacier mummy from the Alps, an increased risk for coronary heart disease was detected. The Iceman’s genome revealed several single nucleotide polymorphisms that are linked with cardiovascular disease in genome-wide association …

Funerary Artifacts, Social Status, And Atherosclerosis In Ancient Peruvian Mummy Bundles, M. Linda Sutherland, Samantha L. Cox, Guido P. Lombardi, Lucia Watson, Clide M. Valladolid, Caleb E. Finch, Albert Zink, Bruno Frohlich, Hillard Kaplan, David E. Michalik, Michael I. Miyamoto, Adel H. Allam, Randall C. Thompson, L. Samuel Wann, Jagat Narula, Gregory S. Thomas, James D. Sutherland

ESI Publications

Background: Evidence of atherosclerotic plaques in ancient populations has led to the reconsideration of risk factors for heart disease and of the common belief that it is a disease of modern times.

Methods: Fifty-one wrapped mummy bundles excavated from the sites of Huallamarca, Pedreros, and Rinconada La Molina from the Puruchuco Museum collection in Lima, Peru, were scanned using computed tomography to investigate the presence of atherosclerosis. Funerary artifacts contained within the undisturbed mummy bundles were analyzed as an attempt to infer the social status of the individuals to correlate social status with evidence of heart disease in …

Why Did Ancient People Have Atherosclerosis?: From Autopsies To Computed Tomography To Potential Causes, Gregory S. Thomas, L. Samuel Wann, Adel H. Allam, Randall C. Thompson, David E. Michalik, M.

ESI Publications

Computed tomographic findings of atherosclerosis in the ancient cultures of Egypt, Peru, the American Southwest and the Aleutian Islands challenge our understanding of the fundamental causes of atherosclerosis. Could these findings be true? Is so, what traditional risk factors might be present in these cultures that could explain this apparent paradox? The recent computed tomographic findings are consistent with multiple autopsy studies dating as far back as 1852 that demonstrate calcific atherosclerosis in ancient Egyptians and Peruvians. A nontraditional cause of atherosclerosis that could explain this burden of atherosclerosis is the microbial and parasitic inflammatory burden likely to be present …

Atherosclerosis: A Longue Durée Approach, L. Samuel Wann, Randall C. Thompson, Adel H. Allam, Caleb E. Finch, Albert Zink, Hillard Kaplan, Bruno Frohlich, Guido P. Lombardi, M.

ESI Publications

Fernand Braudel popularized the longue durée approach to scholarly investigation in the mid-20th century. The longue durée approach can be loosely translated to mean “look for the big picture, synthesize data collected using all available methodology over the long periods of time to identify fundamental principles, rather than becoming preoccupied with isolated observations.” Braudel, a historian and economist, emphasized observation of enduring historical structures and analysis of long-term, panoramic economic trends rather than concentrating on detailed descriptions of particular events or individuals. He also urged the use of insight gained from many scholarly disciplines to identify the essential underpinnings of …

How Portable Is Level-0 Behavior? A Test Of Level-K Theory In Games With Non-Neutral Frames, Shaun Hargreaves Heap, David Rojo Arjona, Robert Sugden

Economics Faculty Articles and Research

We test the portability of level‐0 assumptions in level‐k theory in an experimental investigation of behavior in Coordination, Discoordination, and Hide and Seek games with common, non‐neutral frames. Assuming that level‐0 behavior depends only on the frame, we derive hypotheses that are independent of prior assumptions about salience. Those hypotheses are not confirmed. Our findings contrast with previous research which has fitted parameterized level‐k models to Hide and Seek data. We show that, as a criterion of successful explanation, the existence of a plausible model that replicates the main patterns in these data has a high probability of …

Impact Of Mobile Money Usage On Microenterprise Evidence From Zambia, Laura I. Frederick

Master's Theses

Mobile money payment systems have spread rapidly around the world in the last decade. Given developing countries are powered by informal economies that traditionally have had limited access to information technologies, mobile payment system infrastructure has the potential to transform the way microenterprises conduct business. Through a pilot study in Livingstone, Zambia, I examine the effect of mobile money usage on microenterprise profits. I employ an instrumental variable strategy using the type of mobile operator as the instrument to address the selection bias in adoption, as mobile money services are available to everyone. In this urban context, I find initial …

Typhoons And Lower Birth Weight In The Philippines, Sarah Morrow

Master's Theses

Do typhoons impact birth weights of infants exposed to a typhoon while in utero? This research exploits the exogeneity and randomness of typhoons in the Philippines to estimate the impact of typhoon exposure as determined by wind speed on birth weights. Using four waves of the Demographic and Health Survey (DHS) data from the Philippines combined with temperature, precipitation, and rainfall data from the Philippines, I can empirically estimate the impact of a 1 m/s increase in wind speed on birth weights. I find that for certain subgroups of the population, specifically children born to mothers with primary education or …

Matrilineal Asset Inheritance, Female Bargaining Power, And Household Welfare In Malawi, Nicholas T. Garcia

Master's Theses

Matrilineal inheritance practices in Malawi exogenously determine female land holdings at the time of marriage, allowing for the identification of the effect of increased female bargaining power on household consumption decisions. I use the matrilineal ethnicity of the head of household as an instrument for the share of total household land inherited by the female head or male head’s wife. I find that child’s height-for-age decreases with female assets, and evidence suggesting increased consumption from households’ own production. Since the food basket from own consumption is high in carbs but not nutritious, long-term child health suffers despite receiving more resources …

The Determinants Of Urban Land And Property Values: The Case Of Rwanda, Pierre Kolowe

Master's Theses

Abstract: The paper seeks to determine the factor of urban housing values and their effects on the well-being of urban residents in terms of access to potable water, quality sanitation and other housing amenities. The study uses a total of 36 variables on structural, environmental and neighborhood attributes from the 2010-2011 survey data on income, expenditures and living conditions for the Rwandan urban households. With the use of the semi-log form of the hedonic price model and the survey data, factors of urban properties are determined and quantitative estimates of the Willingness-to-pay for environmental amenities are determined. The analysis of …

Impact Of Natural Disaster Exposure On Prosocial Preferences And Public Goods Provision: Evidence From The Solomon Islands, Heather Belfor

Master's Theses

Natural disaster exposure can impact prosocial preferences, which indicate the level of social capital, as well as create a shift in investments from public to private goods. Both are important mechanisms to study in order to create optimal climate change adaptation policies. This study evaluates the impact of natural disaster exposure on prosocial preferences and public goods provision in the evaluated communities. The data used in this research comes from a process evaluation that was carried out in the Solomon Islands on the Rural Development Program (RDP) and a Structured Community Activity (SCA) experiment, which took place in 80 villages …

The Business Of Beds: An Exploration Of Hotel And Hostel Business Strategy, Robert B. Bunda

Honors Scholar Theses

At their cores, hotels and hostels are similar in that they provide a place for travelers to stay. Despite this core similarity, the structures of the two industries are radically different. The hotel industry began in the Middle Ages and has given rise to massive multinational companies, many managing more than four thousand hotels. In stark contrast, the hostel industry began in 1909 and is mostly comprised of independently owned and operated guesthouses, with the largest global chain comprising of less than twenty properties. This study first defines the hotel and hostel industries and examines the different experiences they offer …

The Impact Of Arrest On Expectations Of Educational Attainment And Criminal Punishment, Kenneth Arbuckle

Renée Crown University Honors Thesis Projects - All

My paper focuses on changes in the expectations of arrested youths. I use the National Longitudinal Survey of Youth 1997 cohort to examine the effects of an arrest on three separate expectations: the expectation of earning a four-year college degree by the age of 30, the expectation of being arrested after stealing a car, and the expectation of being fined and released after stealing a car. In all cases, I isolate those respondents who have been arrested between and not prior to their interview dates in 1997 and 2001. These are the survey rounds in which the expectation questions of …

Too Hot To Handle: Managing America’S Ecosystems In A Changing Climate, Riley Morin

Renée Crown University Honors Thesis Projects - All

For over 140 years, Americans and have enjoyed their national parks. In the national parks, nature and history come together to form uniquely public as well as enormously valuable landscapes. Today, America’s national parks are in danger of undergoing serious changes. Climate change is going to alter the physical characteristics of the national parks. Many of the parks have changed before, but this change will be the most dramatic. In this report I examine the historical and current mission of the National Park Service. I also examine the past and current valuation of the national parks by the American people. …

Land As Power, An Analysis Of Female Land Inheritance And Intrahousehold Bargaining In Rwanda, Eric Adebayo

Master's Theses

Do increased levels of female land inheritance lead to increases in female intrahousehold bargaining power? Analysis of an expansive Rwandan household survey dataset from 2010-2011 suggests that female land inheritances are positively associated with female intrahousehold bargaining power. The results support the relative efficacy of intrahousehold bargaining models over that of unitary household models. The findings have implications for Rwandan lawmakers debating changes to the country's “Succession law” which makes gender discrimination in land inheritance illegal. This is the first paper of its kind to estimate female land inheritance's effect on bargaining power in Rwanda.

Historical Health Conditions In Major Us Cities: The Hue Data Set, Carlos Villareal, Brian Bettenhausen, Eric Hanss, Jonathan Hersh

Economics Faculty Articles and Research

The Historical Urban Ecological data set is a new resource detailing health and environmental conditions within seven major U.S. cities during the study period from 1830 to 1930. Researchers collected and digitized ward-level data from annual reports of municipal departments that detail the epidemiological, economic, and demographic conditions within each city. They then drafted new geographic information system data to link the tabular records to ward geographies. These data provide a new foundation to revisit questions surrounding the urban mortality transition and the growth of U.S. cities.

Economic Voting, Sociotropic Vs. Checkbook: Cases From Greece And Germany, Matthew Coen-Tuff

Political Science Theses and Capstones

Economic voting, the theory that when the economy is good the party in control gains support and when the economy is bad the party in power suffers. This is a simplistic definition and economic voting is so much more. In this paper I seek to prove how economic voting can be broken down into two categories, sociotropic and checkbook. I do this by looking at two countries in very different situation. Greece is a country going through economic turmoil and is constantly changing which party is in control of the government. It has been suffering especially hard from a debt …

Employment Protection And Income Inequality: Is There A Role For The Informal Sector?, Eleni Gkinni, Eleni Vasilaki

Undergraduate Economic Review

This paper seeks to examine the effect of employment protection on income inequality. By employing the employment protection data developed by Botero et al. (2004) as well as well established measures of economic inequality for a sample of 83 countries, our analysis suggests that increased employment protection is negatively associated with income inequality. This relationship remains highly robust across several different specifications and estimation methods. In addition, our analysis places the spotlight on the role of the informal economy and investigates how the presence of informal sector may affect the above mentioned relationship. Our results suggest that in the presence …

Which Extramural Scientists Were Funded By Nih From Its Arra Funds?, Martin D. Sorin, Randall Hannum

Publications and Research

NIH distributed $10 billion of ARRA research funds among Principal Investigators (PIs) in 2009-2010. We studied how well the program achieved the goal of creating and retaining jobs. To analyze the distribution of ARRA funding among PIs, they were categorized in two ways: One was based on their history of research funding; the other on the type of funding, ARRA and non-ARRA, each received in 2009 and 2010. These classifications provide insights into who received ARRA funding and how many research PI jobs were created or retained. We found that the majority of ARRA award recipients already had grants and …
