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.

Valuing Intellectual Property Rights in an Imperfectly Competitive Market: A Biopharming Application AgEcon
Kostandini, Genti; Mills, Bradford F..
Small research firms developing biotechnology applications often focus on establishing intellectual property rights (IPRs), which can then be sold to more established firms with existing market channels. This paper presents a method for valuing the IPRs for an innovation that lowers product production costs below those associated with the patented process of a monopolist. The application to Glucocerebrosidase enzyme from transgenic tobacco suggests an IPRs value of about $1.75 billion. Despite the innovator’s market power, significant surplus gains also accrue to consumers. Further, U.S. antitrust laws that prohibit IPRs acquisition by the current monopolist increase consumer welfare by almost 50%.

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...

THE ECONOMIC IMPACT OF GENETICALLY MODIFIED ORGANISMS IN SMALL DEVELOPING COUNTRIES AgEcon
Hareau, Guy Gaston; Mills, Bradford F.; Norton, George W.; Bosch, Darrell J..
The expected benefits from herbicide resistant transgenic rice in Uruguay are estimated with stochastic simulation techniques. Economic surplus methods that account for private profits are used to measure the magnitude and distribution of the benefits between producers and a multinational firm. Further, the adoption rate of transgenic rice is endogenous in the model and depends on the expected profitability of the technology. The results show that the potential benefits from the technology are relatively small because of the small production base. Multinational firms are, therefore, unlikely to develop locally adapted transgenic rice varieties without strategic partnerships with local institutions.

UNDERSTANDING THE RURAL - URBAN DIGITAL DIVIDE AgEcon
Whitacre, Brian E.; Mills, Bradford F..
This paper explains the current "‘digital divide"’ in internet use between rural and urban areas using a Logit adoption model with data collected from the August 2000 Current Population Survey. A non-linear decomposition shows that rural – urban household attribute differences account for 66 percent of the digital divide, while place based differences account for the remaining 34 percent of the divide.

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...

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.

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.

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...

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...

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.

The Role of Infrastructure in the Rural - Urban Digital Divide AgEcon
Whitacre, Brian E.; Mills, Bradford F..
A significant gap exists in the percentage of rural and urban households that connect to the Internet. Furthermore, this "digital divide" has been increasing with respect to high-speed connections. The primary course of action to address this emerging high-speed digital divide has been to subsidize digital communications technology (DCT) infrastructure. This paper explores the diffusion of DCT infrastructure in both rural and urban areas over the period 2000 - 2003, and estimates its contribution to the emerging divide in high-speed access. The findings suggest that the rural - urban high-speed divide is more strongly associated with differences in household characteristics like education and income than differences in infrastructure.

The Dynamics of Food Stamp Program Participation: A Lagged Dependent Variable Approach AgEcon
Atasoy, Sibel; Mills, Bradford F.; Parmeter, Christopher F..
This paper investigates the existence of Food Stamp Program (FSP) participation state dependence and its sources in by analyzing the dynamics of participation in the FSP using a lagged dependent variable approach. Results show that FSP receipt in the previous year is an important determinant of current FSP receipt. However, estimated persistence rates declined significantly after 1996, suggesting that long-term FSP dependency was reduced following broader welfare reform measures. The source of FSP state dependence among low-income households is mostly structural implying that a welfare trap does exist.

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.
