A Need for Speed? Rural Internet Connectivity and the No access / Dial-up / High-speed Decision AgEcon
Whitacre, Brian E.; Mills, Bradford F..
As residential high-speed Internet access has become more prevalent, the composition of the “"digital divide"” between rural and urban households has shifted. In 2000, dial-up access rates in rural household lagged behind their urban counterparts by eleven percent. By 2003, however, dial-up access rates were equal between rural and urban households, due in part to soaring high-speed rates in urban areas. This paper explores the household decision between no Internet access, dial-up access, and high-speed access. In particular, nested logit and multinomial logit specifications are compared. The paper also uses a decomposition technique to estimate the contributions of various factors (including education, income, and infrastructure levels) to each of...

Arroz Transgénico en Uruguay: un modelo de simulación para estimar los beneficios económicos potenciales. AgEcon
Hareau, Guy Gaston; Mills, Bradford F.; Norton, George W..
economic surplus, imperfect markets, adoption rate, GMO, monopoly power.
Tipo: Book Palavras-chave: En pequeños países en desarrollo como Uruguay; Los beneficios económicos potenciales que se obtendrían por la adopción de nuevas tecnologías agrícolas basadas en biotecnología están limitados por una base productiva reducida. En este trabajo se evalúa ex - ante el impacto económico de una variedad de arroz transgénico resistente a herbicidas donde el poder de mercado de la multinacional propietaria de la variedad afecta las tasas de adopción a través del margen monopólico en el precio de la semilla. Se emplean métodos de simulación estocástica para estudiar la variación de los resultados a cambios en los parámetros tecnológicos y en las tasas de adopción. La media del excedente económico de los productores es de US$1; 82 millones; Mientras que la ganancia monopólica es de US$0; 55 millones. Estos beneficios económicos relativamente escasos sugieren que; Sin estrategias de política pública que incrementen los beneficios potenciales y reduzcan los costos de investigación; Las multinacionales no invertirían recursos significativos en el desarrollo de una variedad transgénica adaptada a las condiciones locales. Las alianzas con instituciones nacionales y el acceso a mercados regionales ampliados también contribuyen a incrementar los incentivos privados en I&D.; Agricultural and Food Policy; Research and Development/Tech Change/Emerging Technologies; C14; E17; Q16; Q18; Q55.

CHANGES IN THE WELL-BEING OF NONMETROPOLITAN SINGLE-MOTHER FAMILIES: A SEMI-PARAMETRIC ANALYSIS AgEcon
Mills, Bradford F..
In nonmetropolitan areas of the United States, single-mother families contain a majority of children living below the poverty line. Changes between 1992 and 2000 in the economic well-being of nonmetropolitan single-mother families are examined using kernel density estimation and density reweighting methods. The results show that increased education levels of single mothers and the strengthening of area economic conditions explain much of the observed gains in the economic well-being of this family group. But temporal changes in propensities to work and to be on welfare from 1992 to 2000 have also contributed to observed gains.

Commune Shocks, Household Assets, and Economic Well-Being in Madagascar AgEcon
Mills, Bradford F.; del Ninno, Carlo; Rajemsison, Harivelo.
Rural households in developing countries are buffeted by environmental, social, health and economic shocks. This paper provides an empirical vignette of the frequency and spatial distribution of such shocks in Madagascar. The association between shocks, community and household assets, and levels of economic well-being (as measured by per-capita expenditures) is then explored, along with the implications for reducing levels of chronic poverty.

Do Rural Community Colleges Supply Unique Educational Benefits? AgEcon
Mykerezi, Elton; Kostandini, Genti; Mills, Bradford F..
Community colleges likely draw to college individuals who would otherwise not attend due to their low costs and open admission requirements. This is labeled as the democratization effect. They may also divert individuals away from 4-year to terminal 2-year college degrees (the diversion effect). This study estimates democratization and diversion effects separately for nonmetropolitan and metropolitan youth using nationally representative data and models that account for endogenous institution selection. We find the democratization effect to exceed the diversion effect of community colleges for both metro and nonmetro youth. The democratization-diversion ratio is slightly higher for urban youth.

Education and Socioeconomic Well-Being in Racially Diverse Rural Counties AgEcon
Mykerezi, Elton; Mills, Bradford F.; Gomes, Sonya.
This paper examines trends in the socioeconomic well-being in rural counties where Black residents represent one third or more of the population. These racially diverse rural counties (RDRCs) are located exclusively in the rural South and generally have low levels of economic well-being. On a positive note, college education levels in RDRCs are found to have increased rapidly between 1990 and 2000. Regression analysis suggests that these increases were in part due to the concentration of Historically Black Colleges and Universities in the region. Local investments in K-12 education are also found to be linked to county education levels.

Ex-Ante Analysis of the Benefits of Transgenic Drought Tolerance Research on Cereal Crops in Low-Income Countries AgEcon
Kostandini, Genti; Mills, Bradford F.; Omamo, Steven Were; Wood, Stanley.
This paper examines the ex-ante benefits of transgenic research on drought in eight developing countries, including the potential magnitude of private sector profits. The framework employs country-specific agroecological-drought risk zones and considers both yield increases and yield variance reductions when estimating producer and consumer benefits from research. Risk benefits from yield variance reductions are shown to be an important component of aggregate drought research benefits, representing 41 percent of total benefits across the eight countries. Further, estimated annual benefits of $US 93 million to the private sector suggest that significant incentives exist for private sector participation in varietal drought tolerance research.

Intensity of Food Stamp Use and Transient and Chronic Poverty: Evidence from the Panel Study of Income Dynamics AgEcon
Atasoy, Sibel; Mills, Bradford F.; Mykerezi, Elton.
The relationship between food assistance and inter-annual family poverty dynamics is examined using data from the 1995-2003 Panel Study of Income Dynamics. We generate expenditure-based poverty measures to examine the determinants of transient and chronic poverty, with particular focus on the differential role that Food Stamp Program (FSP) participation may have on each dimension of poverty. Results indicate that transient poverty accounts for a larger share of economic hardship than chronic poverty. Both dimensions of poverty are reduced at nearly the same rate by additional months of FSP participation. In general, the determinants of chronic and transient poverty are not found to differ significantly; both aspects of poverty appear to be correlated with...

Market Strategies for a Tobacco Bio-Pharming Application: The Case of Gaucher's Disease Treatment AgEcon
Kostandini, Genti; Mills, Bradford F..
Small firms developing biotechnology applications often focus on establishing intellectual property rights, which can then be sold to more established firms with existing market chains. This paper explores the expected 'Buyout' price and economic surplus changes for an emerging bio-pharming application with transgenic tobacco. The results suggest a 'Buyout' price of about $1.75 billion. Yet despite this potentially large payout to the innovating firm, consumers also see significant surplus gains.

NON-METROPOLITAN TO METROPOLITAN AREA MIGRATION OF YOUNG ADULTS AgEcon
Mills, Bradford F.; Hazarika, Gautam.
The decisions of young adults from non-metropolitan areas to either migrate to metropolitan areas or remain in non-metropolitan areas following the completion of schooling are studied in this paper. The migration decision is decomposed into an hourly initial earnings component and a cost component comprising the financial, psychic, and employment attainment costs of migration. There are three noteworthy findings. First, while the propensity to migrate increases in educational attainment, contrary to conventional wisdom, this is entirely attributable to lower costs to migration among more educated individuals. Second, weak local economic conditions exert a strong influence on migration behavior. Specifically, high local unemployment rates and low...

On Intra-Annual Poverty in the U.S.: Prevalence, Causes and Response to Food Stamp Program Use AgEcon
Mykerezi, Elton; Mills, Bradford F..
Poverty measurement with data whose reference period is one year masks family exposure to poverty that only lasts for part of the year. We use quarterly expenditure data and decomposable severity of poverty indexes to quantify consumption-based intra-annual poverty, determine its causes and its response to federal food assistance. Results show that twice as many households are poor for at least one quarter then would be classified as poor with annual consumption data. Severity indexes indicate that intra-annual poverty accounts for over one third of the total annual severity of poverty. The common determinants of intra-annual and annual poverty include low human capital, unemployment and minority status. Changes in family size during the year affect...

POTENTIAL BENEFITS OF TRANSGENIC RICE IN ASIA: A GENERAL EQUILIBRIUM APPROACH AgEcon
Hareau, Guy Gaston; Norton, George W.; Mills, Bradford F.; Peterson, Everett B..
A general equilibrium model is developed to analyze the welfare effects of transgenic technologies for both the irrigated and non-irrigated rice ecosystems in Asia. Drought resistance, a technology of particular importance to unfavorable environments, is worth as much as Bt rice, a technology of primary importance to favorable environments.

Read the Label! Energy Star Appliance Awareness and Uptake Among U.S. Consumers AgEcon
Murray, Anthony G.; Mills, Bradford F..
The Energy Star label program to promote the diffusion of energy efficient home appliances is arguably the most significant government effort to reduce U.S. residential energy consumption. Program effectiveness requires that consumers are aware of the labeling scheme and also change their purchase decisions based on label information. This paper examines the factors associated with consumer awareness of the Energy Star label of recently purchased ‘white’ major appliances and the factors associated with the choice of Energy Star labeled appliances. The paper finds that household characteristics have a much stronger association with consumers awareness of labels than with the choice of Energy Star appliances. Renting the home, Hispanic ethnicity, being poor...
