THE BUTCHER THE BAKER THE PHARMACEUTICAL MAKER: WHY THE AGRICULTURAL BIOTECH INDUSTRY MAY DIFFER FROM THE GENERAL BIOTECH INDUSTRY AgEcon
Dierker, Daniel A.; Phillips, Peter W.B..
This paper explores the apparent anomaly in the patenting strategies found in the agricultural biotechnology industry, when it is compared to the literature's view of the patenting strategies in the general biotechnology industry and in the pharmaceutical industry in particular. By extending an extensive game model of the agriculture biotechnology industry, we show that, like the rest of the biotechnology industry, the integration of the agriculture biotechnology industry into several large private research firms with accompanying government laboratories can be transactions-costs limiting and thus efficient, given the existing institutional structure. A review of the literature respecting the general biotechnology industry reveals an apparent anomaly...

Das neue Gentechnikgesetz – ein Gentechnikverhinderungsgesetz? Eine umweltökonomische Analyse der haftungsrechtlichen Neuerungen im Gentechnikgesetz AgEcon
Becker, Alexander; Holm-Muller, Karin.
In this article, legal consequences of the new German genetic engineering act are analyzed. In addition environmental economic analysis is presented of those parts of the act that introduce new litigation regulation to farmers. The different kinds of external costs arising from genetic engineering of plants and their allocation to different actors are considered. The paper focuses on the costs resulting from the postulated coexistence of conventional/organic farms and users of biotechnology. Excessive liability of farmers can be avoided, if the producers of genetically modified seeds accept any litigation claims against farmers. Furthermore, negotiations between neighbouring farms can be an option to keep the costs of damage prevention at reasonable levels.

ESTIMATION OF TECHNOLOGICAL CHANGE IN THE PASTORAL ZONE AgEcon
te Kloot, Jack H.; Anderson, Jock R..
Measurement of rates of technological change is frequently done in the context of the production function. While measurement suffers problems ranging from conceptual to statistical, this study focuses on the dependence of measurements on the algebraic form of the function specified and the statistical approach adopted. The data relate to an individual property in the central western Queensland sheep country.

The Fragility of Social Capital AgEcon
Antoci, Angelo; Sabatini, Fabio; Sodini, Mauro.
This paper addresses two hot topics of the contemporary debate, social capital and economic growth. Our theoretical analysis sheds light on decisive but so far neglected issues: how does social capital accumulate over time? Which is the relationship between social capital, technical progress and economic growth in the long run? The analysis shows that the economy may be attracted by alternative steady states, depending on the initial social capital endowments and cultural exogenous parameters representing the relevance of social interaction and trust in well-being and production. When material consumption and relational goods are substitutable, the choice to devote more and more time to private activities may lead the economy to a “social poverty trap”,...

Rural Broadband At A Glance, 2009 Edition AgEcon
Stenberg, Peter L.; Low, Sarah A..
Three-quarters of U.S. residents used the Internet to access information, education, and services in 2007. Broadband Internet access is becoming essential for both businesses and households; many compare its evolution to other technologies now considered common necessities—such as cars, electricity, televisions, microwave ovens, and cell phones. Although rural residents enjoy widespread access to the Internet, they are less likely to have high-speed, or broadband, Internet access than their urban counterparts. Circumstantial evidence suggests that the difference in access may lie in the higher cost and limited availability of broadband Internet in rural areas. As a result, rural residents depend more on Internet use outside of the home, in places like the...

Cereal Marketing and Household Market Participation in Ethiopia: The Case of Teff, Wheat and Rice AgEcon
Gebremedhin, Berhanu; Hoekstra, Dirk.
Teff, wheat and rice are becoming important market oriented crops in Ethiopia. This study aims at analyzing the market participation of farm households, market actors, market channels and determinants of household market participation for these crops. Results are based on analysis of data collected from community and household surveys in three districts in three regional states of the country in 2005. Analysis of descriptive information and econometric analysis are used. About 65 - 77% of households produce these market oriented commodities, on about 27 – 44% of the total cultivated area. About 47 – 60% of the produce of these market oriented commodities is sold. The important market places for producers of these commodities are the district town markets...

Factors Influencing the Temporal Diffusion of Broadband Adoption: Evidence from Oklahoma AgEcon
Whitacre, Brian E..
This paper examines the shifting influence of household characteristics and telecommunications infrastructure on the residential broadband adoption decision for Oklahoma residents between 2003 and 2006. In particular, the spread of wired telecommunications infrastructure (namely cable Internet and Digital Subscriber Lines (DSL)) is examined, along with the effect that this diffusion has had on broadband access rates. The data indicates that the gap in broadband access rates between rural and urban areas has remained relatively constant over this period despite increased levels of cable and DSL throughout the state. In addition, an inter-temporal decomposition shows that the increasing levels of infrastructure are not the dominant cause of higher broadband...

The 24th hour of agricultural research AgEcon
Vida, Adrienn; Baksa, Adrienn.
Economic and social changes occurring in Hungary and all over the world mean new challenges for sciences. This trend goes also for agriculture; globalization, climate change, the increase in population and food demand, and the decrease of land used for food production at the same time cause problems that can be solved by means of sciences. The year 2007 was the beginning of a new era in agriculture and rural development. The financial period of 2007-2013 presents an essentially new situation in the European Union, so agricultural universities, high schools and research institutes, as well as market operators must undertake serious changes. As Hungary is basically an agricultural country; agriculture plays an important role in national economy, therefore...

Information, ICTs and Ethical Trade: Implications for Self-Regulation AgEcon
Duncombe, Richard; Heeks, Richard.
Increasing numbers of ethical trade initiatives are being launched, reflecting concerns about the limited benefits that globalisation brings to producers in developing countries. Ethical trade is an information-intensive activity yet little is known about the role of information systems in supporting this activity. Ethical trade - with its voluntary codes and consumer campaigns - also represents a new approach to interaction between market actors. This form of self-regulation is seen as an alternative to state regulation and sanctions, and more appropriate to a liberalised international economy. This paper provides a summary of the literature concerning ethical trade, selfregulation and the role of information. It presents models and issues in relation to...

Animal Disease and the Industrialization of Agriculture AgEcon
Hennessy, David A.; Wang, Tong.
The industrialization of animal agriculture has fundamentally transformed animal health markets while animal health innovations have promoted this industrialization. The subtlety of these interactions shows how little we know about agricultural industrialization. To illustrate, we consider three stylized features of industrialized animal agriculture. These are the closing off of production activities from external effects, emphasis on control, and use of biosecurity measures. We find that animal disease externalities should lead to higher stocking on any given farm, and also to deficient entry into animal production. Eradicating the disease in a region increases both the stocking rate per farm and the number of farms. We show that antibiotics as a control...

RESEARCH AND ADVERTISING DECISIONS IN AN OPEN ECONOMY: THE CASE OF COLOMBIAN MILDS COFFEE AgEcon
Sellen, Daniel; Goddard, Ellen W..
Research and advertising investment both offer the potential to increase producer surplus. A model is developed that includes applied research and generic advertising with the aim of measuring marginal and optimal returns from each. While applicable to specific firm behavior, the model is applied to data from the world coffee market, with particular focus on Kenyan and Colombian producer groups.

Toward a Research Agenda to Promote Household Access to Food in Ethiopia AgEcon
Jayne, Thomas S.; Molla, Daniel.
The objective of this report is to review available evidence on the potential to promote access to food for vulnerable groups in Ethiopia through two main methods: food transfer programs, and appropriate policies influencing the food marketing system. These issues are examined with a view to identifying priority issues for analysis under the MEDAC/MSU/USAID Food Security Project in Ethiopia. In particular, the report presents trends in food aid and food production in Ethiopia, and provides preliminary evidence of the possible disincentive effects of food aid on agricultural production incentives and investments in the food marketing system; discusses the costs and benefits of various food aid transfer programs, and highlights major unresolved...

Estimating the Market Effect of a Food Scare: The Case of Genetically Modified StarLink Corn AgEcon
Carter, Colin A.; Smith, Aaron D..
Genetic modification of crops has revolutionized food production, but it remains controversial due to food safety and environmental concerns. A recent food safety scare provides a natural experiment on the corn market's willingness to accept unapproved genetically modified organisms. In 2000, a genetically modified corn variety called StarLink was discovered in the food-corn supply, even though it was not approved for human consumption. To estimate the price impact of this event, we develop the relative price of a substitute method, which applies not only to the StarLink event but also to rare events in other markets. We apply this method to measure the price impact of the StarLink contamination on the U.S. corn market. We find that the contamination led...

Accounting for Uncertainty Affecting Technical Change in an Economic-Climate Model AgEcon
Bosetti, Valentina; Drouet, Laurent.
The key role of technological change in the decline of energy and carbon intensities of aggregate economic activities is widely recognized. This has focused attention on the issue of developing endogenous models for the evolution of technological change. With a few exceptions this is done using a deterministic framework, even though technological change is a dynamic process which is uncertain by nature. Indeed, the two main vectors through which technological change may be conceptualized, learning through R&D investments and learning-by-doing, both evolve and cumulate in a stochastic manner. How misleading are climate strategies designed without accounting for such uncertainty? The main idea underlying the present piece of research is to assess and...

WILLINGNESS TO PAY FOR AGRICULTURAL RESEARCH AND EXTENSION PROGRAMS AgEcon
Clifford, William B.; Hoban, Thomas J.; Whitehead, John C..
The North Carolina Agriculture Survey was designed to estimate the willingness to pay for agricultural research and extension programs. We find that North Carolina households are willing to pay between $218 and $401 million for food production programs and between $251 and $698 million for water quality programs annually. We find evidence of divergent validity and differences in the willingness to pay estimates from the single-bound and multiple-bound data.
