Climate Underground: The Effects Of Climate Variability On Groundwater Irrigation, 2019 University of Colorado, Boulder
Climate Underground: The Effects Of Climate Variability On Groundwater Irrigation, Monica Gronseth
Undergraduate Honors Theses
This study addresses the question of groundwater use sensitivity to changes in climate. We use county fixed effects models to empirically estimate the effect of climatic changes during the growing season on groundwater use for irrigation. This study uses data from USGS reports on industry water use and weather data from NOAA. We find both precipitation and temperature have a significant effect on groundwater irrigation, with particular prominence in areas with lower annual precipitation on average. These effect estimates are then used to model the effects of climate change on groundwater irrigation by the end of the century. We conclude ...
Earning A Higher Celery: A Participatory Impact Assessment Of The Nabasunga Primary School Garden, 2019 University of Colorado, Boulder
Earning A Higher Celery: A Participatory Impact Assessment Of The Nabasunga Primary School Garden, Anika Bernstein
Undergraduate Honors Theses
This thesis investigated the impacts of a garden at the Nabasunga Primary School (NPS) in Zambia. Community gardens can improve economic stability, local food supply, health, and education. In 2017, the Day by De Foundation provided the resources for a community garden in the NPS. An established framework, the Participatory Impact Assessment (PIA), was applied to assess the garden to determine whether a chicken farm should be added on. Fifteen individual stakeholders, including teachers, parents, and community members of at least 18 years of age and living in the Nabasunga community were surveyed in retrospect to the garden’s implementation ...
The Effect Of Water And Sanitation Privatization On Child Mortality Rates In Guayaquil, Ecuador, 2019 University of Colorado, Boulder
The Effect Of Water And Sanitation Privatization On Child Mortality Rates In Guayaquil, Ecuador, Brian Lambert
Undergraduate Honors Theses
A strong debate continues in economics over whether privatization of water and sanitation resources is beneficial in developing countries. This paper analyzes mortality and census data in the years 1990- 2010 from the Ecuadorian National Institute of Statistics and Censuses to determine how the privatization of water and sanitation in Guayaquil, Ecuador has affected water-related mortality rates in the city. In this analysis, I conduct a difference-in-difference regression analysis with the under-three, under-five, and under-ten water-related mortality rate as my dependent variable, and the event of water privatization as my independent variable. In this investigation, I find that water privatization ...

Accounting For Agent Heterogeneity In Market And Policy Analysis, 2019 University of Nebraska-Lincoln
Accounting For Agent Heterogeneity In Market And Policy Analysis, Konstantinos Giannakas
This book presents a multi-market framework of market and policy analysis that explicitly accounts for the empirically relevant heterogeneity in consumer preferences and producer characteristics. The explicit consideration of consumer and producer heterogeneity represents a significant departure from the representative consumer and producer that have been at the center of most of the literature on market and policy analysis, and enables the distributional impacts of changes in market conditions and policies to be fully identified. The framework is used to analyze the system-wide market and welfare impacts of a number of changes in market conditions (like ...
International Trade Policy: Insights From A General-Equilibrium Approach, 2019 Iowa State University
International Trade Policy: Insights From A General-Equilibrium Approach, Edward J. Balistreri
Agricultural Policy Review
IT IS easy to convince Iowa farmers that the trade war with China has substantial costs, as current agricultural commodity prices reflect reduced export demand. Rather than bear the burden of retaliatory tariffs, China moved toward other sources and substitutes for soybeans (see related article by Chad Hart and Lee Schultz in this issue of the APR) . The adverse export-demand shock is absorbed within the US market by inventory (and eventually production) adjustments and price reductions, and farm revenues fall as a result. This narrative might well outline the primary mechanism by which many Iowa farmers feel the pain of ...

Developing Agricultural Curriculum For Betty Memorial Institute, A Rural High School In Liberia, 2019 Iowa State University
Developing Agricultural Curriculum For Betty Memorial Institute, A Rural High School In Liberia, Corey Hartbecke
This paper will explore how a collaborative process for developing high school agriculture curriculum was developed between American partners and teachers at Betty Memorial Institute in the rural Tewar District, Grand Cape Mount County, in the Republic of Liberia. The process used is a multidisciplinary approach, where American contributors are researching areas of culture, history and local influences on agriculture in order to become informed partners. The methods introduced provide for curriculum that will fit a complex environment that exists in rural Liberia. Also, this approach allows for relevant contribution to the Liberian teachers, who are the primary developers of ...
Declining Liquidity In Iowa Farms: 2014–2017, 2019 Iowa State University
Declining Liquidity In Iowa Farms: 2014–2017, Alejandro Plastina
The goal of the present study is to describe the evolution of financial liquidity in Iowa farms for 2014–2017, using a unique panel of 220 mid-scale commercial farms. Farms with vulnerable liquidity ratings increased from 33.2 percent in December 2014 to 45.0 percent in December 2017. On average, farms lost $244 of working capital per acre over that period, but farms with vulnerable liquidity ratings in December 2017 lost almost 60 percent more than that, or $388. Average farm size, machinery investment per acre, farm net worth per acre, debt-to-asset ratio, and age of operator were not ...
Has Specialization Put A Limit On How Far Cattle Contracting Can Go?, 2019 University of California - Davis
Has Specialization Put A Limit On How Far Cattle Contracting Can Go?, John Crespi, Tina L. Saitone
Agricultural Policy Review
I N 1776 Scottish philosopher Adam Smith published An Inquiry into the Nature and Causes of the Wealth of Nations, or as it is better known, The Wealth of Nations. In many mundane ways, Smith merely chronicled the burgeoning European industries he was observing; but, in doing so, he helped spread a revolutionary thinking about how factories could take advantage of specialization. Smith’s discussion of a visit to a pin factory has been re-told so often that many people probably know the story without knowing the source. The story goes like this: If you were to make a pin ...
African Swine Fever In China: An Update, 2019 Iowa State University
African Swine Fever In China: An Update, Wendong Zhang, Dermot J. Hayes, Yongjie Ji, Minghao Li, Tao Zlong
Agricultural Policy Review
LAST NOVEMBER, we wrote an article (Shao et al. 2018) documenting the development of African Swine Fever (ASF) in China and its impacts on regional hog and pork prices. Since then, ASF has continued to ravage China’s hog industry with 62 new cases from November 1, 2018 to March 27, 2019, resulting in a total of 114 cases. The total inventory of hog factories with ASF outbreaks has increased from 61,214 to 319,726 (click here to see an animated map of ASF cases in China). The pace of the outbreaks has somewhat slowed down from more than ...
The Yin And Yang Of Agricultural Trade, 2019 Iowa State University
The Yin And Yang Of Agricultural Trade, Lee L. Schulz, Chad Hart
Agricultural Policy Review
IT’S A fascinating, but uncertain, time in the agricultural markets. Global and US supplies of agricultural products are at or near record levels. At the same time, global demand for agricultural products continues to grow, pressured by both population and income growth. Markets work to distribute the products across the globe, and government policies can definitely shape that distribution. Myriad new trade agreements, trade disputes, and tariffs introduced over the last 15 months are reshaping global agricultural trade lows. Some of that reshaping has been beneficial to US producers, while some of it has been harmful. Trade policy does ...
Criar Y Dejarse Criar: Trans-Situ Crop Conservation And Indigenous Landscape Management Through A Network Of Global Food Neighborhoods, Cass Madden
As climate change progresses, global food security is likely to become increasingly threatened and crop biodiversity will be a significant source of resiliency and adaptability. However, these adaptations will only be fully realized through cooperative in situ and ex situ conservation and cultivation of domesticated crops, crop wild relatives, and wild foods. This conservation is best realized in places where communities have the cultural resources to invest meaningfully in the cultivation of native crops, and where the cultivation of those crops can reinforce place-specific livelihoods and identities. To this end, the principal objective of this research is to propose a ...
Utilizing Large Scale Datasets To Evaluate Aspects Of A Sustainable Bioeconomy, 2019 University of Kentucky
Utilizing Large Scale Datasets To Evaluate Aspects Of A Sustainable Bioeconomy, Gwanseon Kim
Theses and Dissertations--Agricultural Economics
This dissertation combines large scale datasets to evaluate crop prediction, land values, and consumption of a crop being considered to advance a sustainable bioeconomy. In chapter 2, we propose a novel application of the multinomial logit (MNL) model to estimate the conditional transition probabilities of crop choice for the state of Kentucky. Utilizing the recovered transition probabilities the forecast distributions of total acreages for alfalfa, corn, soybeans, tobacco, and wheat produced in the state from 2010 to 2015 can be recovered. The Cropland Data Layer is merged with the Common Land Unit dataset to allow for the identification of crop ...
Adaptation Under The Canopy: Coffee Cooperative And Certification Contributions To Smallholder Livelihood Sustainability In Santa Lucía Teotepec, Oaxaca, Meghan C. Montgomery
Graduate Student Theses, Dissertations, & Professional Papers
The collapse and reorganization of global coffee markets associated with the “coffee crisis” have had profound, negative impacts on smallholder producer livelihoods throughout the world. In Mexico, the collapse of the International Coffee Agreement (ICA) coincided with withdrawal of government support for agriculture, which devastated producers dependent on coffee for their livelihoods. Smallholders responded by shifting livelihood strategies to diversify income, migrating, and converting primary forest cover to subsistence crops and pasture to support household livelihood security. In some instances, producers also joined or formed cooperative organizations to access specialty certifications that offer higher priced markets, extension information, and other ...

Model-Based Analysis In Survey: An Application In Analytic Inference And A Simulation In Small Area Estimation, 2019 Iowa State University
Model-Based Analysis In Survey: An Application In Analytic Inference And A Simulation In Small Area Estimation, Zhenzhen Chen
This paper addresses model-based procedures in data analysis for national complex data and a simulation study in small area estimation. For National Agriculture Workers Survey data, we do variable selection and want to find one model based on Akaike information criterion (AIC). We use augmented model and weighting approach to deal with the survey weight, equal weight, and smoothed weight. Research result indicates that the survey weight plays an important role in model selection. We also show what variables are significant predictors for the number of years farm workers are employed in their current employer. For small area estimator, we ...
Social Determinants Of Health Theory: Policy Entry Points For Healthcare Providers, 2019 University of Denver
Social Determinants Of Health Theory: Policy Entry Points For Healthcare Providers, Kiah R. Vandergrift
Electronic Theses and Dissertations
This thesis examines a shifting paradigm in the U.S. healthcare system that will re-define the role that the healthcare provider plays in the production of health. It does this by first acknowledging two differing economic theories on the production of health: Human Capital Theory and Social Determinants of Health theory, and how both schools of thought have contributed to the paradigm that healthcare providers only play a role in the end stages of health production - to heal those who are already ill. However, policy, payment, and delivery system reforms have begun to force healthcare providers to re-think how they ...

The Cost Of Forest Preservation In The Brazilian Amazon: The “Arc Of Deforestation”, 2019 Clemson University
The Cost Of Forest Preservation In The Brazilian Amazon: The “Arc Of Deforestation”, Felipe De Figueiredo Silva, Lilyan E. Fulginiti, Richard Perrin
Faculty Publications: Agricultural Economics
We estimate the trade-off between agricultural production and forest preservation for the municipalities in Brazil’s agricultural frontier, the so-called “arc of deforestation,” using census and deforestation data for 2006. We use a nonparametric directional output distance function that allows us to identify the gradients of the production possibility frontier, which are the trade-offs of interest. We found that, on average, $979 is forgone in annual livestock, timber, and grain revenues to conserve 1 hectare of forest. This translates, ceteris paribus, to an average present value of costs to permanently sequester CO2 of $16.36/t, higher than most previous ...
