Helminth Infection, Fecundity, And Age Of First Pregnancy In Women, Aaron D. Blackwell, Marilyne D. Tamayo, Bret Beheim, Benjamin C. Trumble, Jonathan Stieglitz, Paul L. Hooper, Melanie Martin, Hillard Kaplan, Michael Gurven

ESI Publications

Infection with intestinal helminths results in immunological changes that influence the odds of comorbid infections, and might also affect fecundity by inducing immunological states supportive of conception and pregnancy. Here we investigate associations between intestinal helminths and fertility in human females, utilizing nine years of longitudinal data from 986 Bolivian forger-horticulturalists, experiencing natural fertility and a 70% helminth prevalence. We find that different species of helminth are associated with opposing effects on fecundity. Infection with roundworm (Ascaris lumbricoides) is associated with earlier first births and shortened interbirth intervals, while infection with hookworm is associated with delayed first pregnancy and extended …

Natural Sleep And Its Seasonal Variations In Three Pre-Industrial Societies, Gandhi Yetish, Hillard Kaplan, Michael Gurven, Brian Wood, Herman Pontzer, Paul R. Manger, Charles Wilson, Ronald Mcgregor, Jerome M. Siegel

ESI Publications

How did humans sleep before the modern era? Because the tools to measure sleep under natural conditions were developed long after the invention of the electric devices suspected of delaying and reducing sleep, we investigated sleep in three preindustrial societies[1–3]. We find that all three show similar sleep organization, suggesting that they express core human sleep patterns, likely characteristic of pre-modern era Homo sapiens. Sleep periods, the times from onset to offset, averaged 6.9–8.5-h, with sleep durations of 5.7–7.1-h, amounts near the low end of those industrial societies[4–7]. There was a difference of nearly 1-h between summer and winter sleep. …

More Educated And More Equal? A Comparative Analysis Of Female Education And Employment In Japan, China And India, Sucharita Sinha Mukherjee

Economics Faculty Publications

This paper attempts to explore the connections between expanding female education and the participation of women in paid employment in Japan, China and India, three of Asia's largest economies. Analysis based on existing data and literature shows that despite the large expansion in educational access in these countries in the last half century, women have lacked egalitarian labour market opportunities. A combination of social discouragement and individual choice largely explains the withdrawal, non-participation or intermittent female presence in the labour force, notwithstanding increased educational access. In taking stock of these issues and debates across these countries, it is argued that …

Living Arrangements And Psychological Well-Being Of The Elderly After The Economic Transition In Vietnam, Ken Yamada, Bussarawan Teerawichitchainan

Research Collection School of Social Sciences

Objectives: We examine the relationship between living arrangements and psychological well-being of the older adults in Vietnam, where there is an influence of Confucian values and a lack of close substitutes for family care of the older adults, by exploiting a great deal of regional variation in economic development. We also examine the role of living arrangements in well-being differentials across regions. Method: We estimate a triangular simultaneous-equation discrete-response model, which accounts for the simultaneity between living arrangements and psychological well-being (happiness, depression, loneliness, poor appetite, and sleep disorder), using a nationally representative sample of 2,225 adults aged 60 and …

Remittances Without Borders, Tan Swee Liang, S. N. Venkataramanan, Anil Kishora

Research Collection School Of Economics

A Pan-Asian Mobile Remittance Platform might just be the next big disruption in global remittances. One out of every 28 people lives in a country that they were not born in. As migrants, they are estimated by The World Bank to send home US$636 billion in 2017, with three-quarters remitted to developing countries. These remittances form a significant percentage of the Gross Domestic Product (GDP) of many of these developing countries. Given their magnitude and contribution to national economies, even a small reduction in remittance cost adds billions to these local economies. Mobile-to-mobile cross border remittances have recently shown that …

Cointegration Of Matched Home Purchases And Rental Price Indexes: Evidence From Singapore, Badi H. Baltagi, Jing Li

Research Collection School Of Economics

This paper exploits the homogeneity feature of the Singapore private residential condominium market and constructs matched home purchase price and rental price series using the repeated sales method. These matched series allow us to conduct time series analysis to examine the long-term present value relationship in the housing market. Three key findings are obtained. First, we fail to establish a cointegrating relationship between the home purchase price and rental price based on nationally estimated indexes. Second, area-specific indexes demonstrate strong cross-correlations, invalidating the use of first generation panel unit root tests that ignore these cross-correlations. Third, Pesaran's CIPS test indicates …

Calcaneal Quantitative Ultrasound Indicates Reduced Bone Status Among Physically Active Adult Forager-Horticulturalists, Jonathan Stieglitz, Felicia C. Madimenos, Hillard Kaplan, Michael Gurven

ESI Publications

Six months of exclusive breastfeeding (EBF) is considered optimal for infant health, though globally most infants begin complementary feeding (CF) earlier—including among populations that practice prolonged breastfeeding. Two frameworks for understanding patterns of early CF emerge in the literature. In the first, maternal and infant needs trade-off, as “maternal-centric” factors—related to time and energy demands, reproductive investment, cultural influences, and structural barriers— favor supplanting breastfeeding with earlier and increased CF. A second framework considers that “infant-centric” factors—related to infant energetic needs—favor CF before six months to supplement breastfeeding.

We apply these two frameworks in examining early CF among the Tsimane—a …

Homegrown Or Imported? Frugal Innovation And Local Economic Development In Zambia, Iva Peša

Southern African Journal of Policy and Development

Innovation and entrepreneurship have the potential to stimulate economic growth. Yet it remains unclear whether top-down or bottom-up innovations are more likely to lead to local economic development. By looking at three cases of frugal innovation on the Zambian Copperbelt, in the spheres of housing, water and energy, it will be argued that polycentric innovation (which connects local and international actors) is most likely to generate inclusive development. Yet even a polycentric approach does not guarantee desired outcomes, as innovation remains context specific.

The Impact Of Labour Productivity On Economic Growth: The Case Of Mauritius And South Africa, Jack Jones Zulu, Benjamin Mattondo Banda

Southern African Journal of Policy and Development

This study explores the impact of labour productivity on economic growth in Mauritius and South Africa. We establish that investments in physical capital have a positive effect on labour productivity and by implication on economic performance. Labour employment in industry is counterproductive, while the cumulative effect of new technologies on labour productivity is negligible in the three-year intervals. It is the initial stock and subsequent accumulation of human capital that stimulates faster output growth in both countries.

The Making And Re-Making Of Dolpo Identity: A Case Study Of Do-Tarap, Lin Zhu

Independent Study Project (ISP) Collection

The unbelievably harsh environment in Dolpo forces people to be self-sufficient based on agriculture and husbandry, two sectors that complement each other very well. The condition also requires plentiful communal works for survival. Dolpo’s geographical isolation on the one hand, limits Dolpo-pas from encountering others, and on the other hand, prevents the presence of the central government. Before the 1960’s, Dolpo still remained as a politically autonomous region under the Kingdom of Nepal. However, based on interviews conduced with both local villagers and outsiders such as governmental officials and Nepalese, the paper argues that, starting from the 1960’s, Dolpo-pas began …

Monetizing Housing For Retirement In Singapore, Sock Yong Phang

Research Collection School Of Economics

In 2015, the value of housing assets owned by households in Singapore at the aggregate level was 55% of their net worth.1 Ninety percent of Singapore households owned their homes, meaning that almost all households had wealth saved in housing, and households’ housing wealth was 2.1 times that of the country’s gross domestic product. In addition, Singapore is facing an aging population. The resident old age support ratio, defined as the number of persons aged 20–64 per person aged 65 years and over, decreased from 9.0 in 2000 to 5.7 in 2015.2 Against this backdrop of asset-rich and aging households, …

Building A Better Model: Variable Selection To Predict Poverty In Pakistan And Sri Lanka, Marium Afzal, Jonathan Hersh, David Newhouse

Economics Faculty Articles and Research

Numerous studies have developed models to predict poverty, but surprisingly few have rigorously examined different approaches to developing prediction models. This paper applies out of sample validation techniques to household data from Pakistan and Sri Lanka, to compare the accuracy of regional poverty predictions from models derived using manual selection, stepwise regression, and Lasso-based procedures. It also examines how much incorporating publically available satellite data into the model improves its accuracy. The five main findings are that: 1) Lasso tends to outperform both discretionary and stepwise models in Pakistan, where the set of potential predictors is large. 2) Lasso and …

Impact Of International Remittances On Schooling In The Philippines: Does The Relationship To The Household Head Matter?, Tomoki Fujii

Research Collection School Of Economics

We study the impact of international remittances on schooling in the Philippines, taking into account the school-age individual's relationship to the household head. This consideration is important because employment opportunities abroad may be taken at the expense of the quality of child rearing. Our estimation results indicate that there are, indeed, significant negative guardian effects on school attendance and education expenditures when children with overseas parents are looked after by a relative other than a parent or grandparent. However, these negative effects tend to be outweighed by the positive impact of remittance flows from overseas.

Políticas De Precios Y Comercialización Agrícola Durante La Transición: Experiencias Y Lecciones Para Cuba, Mario A. Gonzalez-Corzo

Publications and Research

Las políticas de precios y comercialización de productos agrícolas desempeñaron un importante papel durante las transiciones en los antiguos países socialistas. Estas transiciones agrícolas primordialmente se caracterizaron por el desmantelamiento, en algunos casos como China y Vietnam de forma gradual y calibrada y en otros de forma acelerada como en algunos países de Europa del Este y la Unión Soviética, del colectivismo, los subsidios estatales y los controles de precios y por mayores grados de participación de actores no-estatales en la comercialización de productos agrícolas. A pesar de notables diferencias estructurales y coyunturales, las experiencias de los antiguos países socialistas …

The Zen Of Charity Giving In China: An Understanding Of The Chinese Philanthropic Sector And Recommendations On Moving Towards Sustainability, Li Zheng

Capstone Collection

China has shifted from a centrally planned to a market based economy in 1978. Since then, the country has experienced rapid economic growth and social development. With a more liberal economic environment, the voice of civil society becomes stronger, which incentives the emergence of philanthropy and charitable giving. As a result, the government has begun to encourage private donation and development of foundations, while watching carefully and constraining its activities. By analyzing both qualitative and quantitative data, this paper explores and evaluates the effectiveness of this emerging sector. The paper further advocates for improving current charity law and developing a …

Singapore’S Housing Policies: Responding To The Challenges Of Economic Transitions, Sock Yong Phang

Research Collection School Of Economics

Singapore has developed its own unique state-driven housing system, with more than three quarters of its housing stock built by the Housing and Development Board and homeownership financed through Central Provident Fund savings. As a result, it has one of the highest homeownership rates amongst market economies. This paper provides a historical perspective of the main housing problems faced by successive prime ministers and their respective policy responses. Under the leadership of Prime Minister Lee Kuan Yew (1959-1990), the government established an integrated landhousing supply and housing finance framework to channel much needed resources into the housing sector to deal …

The Role Of The State In Singapore: Pragmatism In Pursuit Of Growth, Kim Song Tan, Manu Bhaskaran

Research Collection School Of Economics

This paper looks at how government intervention shapes the evolution of the Singapore economy and accounts for its successes and failures over the past 50 years. Compared with other dynamic Asian economies, the Singapore government's approach to intervene in the economy is both more extensive and more intrusive, but with a narrow focus on GDP growth and surplus accumulation as the primary objectives. The ruling government's near complete dominance in politics has enabled it to mobilize resources to create the preconditions for strong GDP growth and high savings. But the impact on the broader development of the economy and the …

Does Market Integration Buffer Risk, Erode Traditional Sharing Practices And Increase Inequality? A Test Among Bolivian Forager-Farmers, Michael Gurven, Adrian V. Jaeggi, Christopher Von Rueden, Paul L. Hooper, Hillard Kaplan

ESI Publications

Sharing and exchange are common practices for minimizing food insecurity in rural populations. The advent of markets and monetization in egalitarian indigenous populations presents an alternative means of managing risk, with the potential impact of eroding traditional networks. We test whether market involvement buffers several types of risk and reduces traditional sharing behavior among Tsimane Amerindians of the Bolivian Amazon. Results vary based on type of market integration and scale of analysis (household vs. village), consistent with the notion that local culture and ecology shape risk management strategies. Greater wealth and income were unassociated with the reliance on others for …

Examining The Outcomes Of The Balanced Scorecard (Bsc) As An Integral Tool Of Public Sector: Reform In Selected Sectors Of The Oromia Regional Government, Tolla Berrisso Geda, Daniel Beyera

International Journal of African Development

Over the last two decades Ethiopia has been actively engaged in reforming its public sector in an attempt to make it more responsive, transparent, flexible, and compatible with the demand of its public and its constituencies to ensure good governance. Nevertheless, despite repeated comprehensive reform programs applied and acclaimed success stories by public authorities, the public outcry for responsive public service remains an outstanding challenge. Accordingly, this study aimed to examine the application of the Balanced Score Card (BSC) using a blend of survey and case study methods in 12 organizations selected from three major sectors in four major cities. …

Convalescent Serum Therapy As Rapid Advance Treatment For Ebola In West Africa, J Bankole Thompson Md, Phd, Patricia F. Mejabi Msc., Olugbenga O. Mejabi Phd, S Ahmed Tejan-Sie Md

International Journal of African Development

The 2014 public health crisis in Guinea, Liberia, and Sierra Leone has brought Ebola Viral Disease (EVD) to everyone’s attention. Discovered in 1976, this deadly disease infrequently struck in remote areas of Africa. This article will critically review the literature and describe the pathobiology, transmission, signs and symptoms, diagnosis, treatment, and prevention of EVDwhich, was predicted by the Centers for Disease Control to potentially infect 1.4 million persons in Liberia and Sierra Leone by January 2015 (“Questions and Answers”, 2014). Thankfully this worst case scenario did not occur and we may be experiencing natural burn out of the outbreak along …

Determinants Of Farm And Non-Farm Family-Controlled Child Labor, Kofi Acheampong

International Journal of African Development

Ninety five percent of the child labor in Africa takes place in private households where children are controlled by their relatives. While this is a major problem, the literature provides little discussion on the determinants of this form of child labor. To fill this gap, I examine the determinants of farm and non-farm family-controlled child labor using data from the 2009 Ghana Time Use Survey. The findings indicate that school networks, the education level of the head of household, and religion play important roles in determining children’s activities in both farm and non-farm work.

Ethnographic Study To Understand The Culture Of Technology Manufacturing In Ghana, Yao-Martin Donani

International Journal of African Development

Sub-Saharan African countries are characterized by low or absent technological growth. Scholars and the international community have endeavored to solve the long-standing problem, but none of these have produced the expected growth. While the rest of the world is advancing rapidly, Africa is noticeably lagging, even in comparison to other developing regions. It is apparent that previous international strategies cannot solve Africa’s technological underdevelopment This study argues that a solution to the problem depends on Africans, who must choose to want a solution and work towards it. An ethnographic study was therefore conducted to investigate the attitudes and worldview of …

Development experts are telling increasingly fascinating stories about how human development indices (HDI) among the poor in Africa, Asia, and Latin America have been buoyed by the diffusion of ICTs (Information and Communication Technologies) over the last two decades. According to data compiled by the World Economic Forum, ICTs have facilitated faster and more reliable communication with regard to almost all important spheres of life including healthcare, education, agriculture, commerce, e-banking, the environment, etc. Perhaps the greatest impact of ICTs has been in their democratizing effect and their role in promoting gender equity, especially with regard to access to information …
