THE ECONOMICS OF REFUGE DESIGN FOR BT CORN AgEcon
Hyde, Jeffrey; Martin, Marshall A.; Preckel, Paul V.; Dobbins, Craig L.; Edwards, C. Richard.
Planting Bt corn on large areas may lead to European corn borer (ECB) resistance to Bt. Scientists recommend planting a non-Bt corn refuge as part of a resistance management strategy. Different refuge configurations may impact farm profits differently. This paper analyzes the economics of alternative refuge configurations in Indiana.

OUTSIDE PERSPECTIVES ON AGRIBUSINESS RESEARCH, TEACHING, AND OUTREACH AgEcon
Holder, David L..
Many of my thoughts in this paper come from the author's experience in conducting comprehensive reviews of agricultural economics departments. The author suggests the need to look at the forces affecting the demand for our products and be willing to challenge many of the myths about the structure and performance of the university system and the agribusiness system. Agriculture is losing a lot of its uniqueness and becoming part of the mainstream. Colleges of agriculture have changed considerably in the last 50 years; they will change even more in the next fifty years. What is our unique niche? How willing are we to adapt to its challenges? These questions must be answered in regard to the future of agribusiness research, teaching, and outreach.

Consumer's Attitude Towards Labeled and Unlabeled GM Food Products in Italy AgEcon
Soregaroli, Claudio; Boccaletti, Stefano; Moro, Daniele.
Based on survey data collected on a sample of 500 Italian consumers, this paper evaluates the consumer's attitude towards foods obtained from the application of biotechnologies and foods labeled as "GM free". Results from the application of probit models shows that the probability to purchase GM products is lower for individuals more adverse to risk, older, with higher education and less confident in institutional guarantees. Willingness to Pay for GM free products is positively related to information, risk aversion, age, trust in institutional environment, negatively to the degree of agreement with the application of biotechnologies.

Technical Efficiency Effects of Technological Change: Another Perspective on GM Crops AgEcon
Weaver, Robert D.; Curtiss, Jarmila; Brümmer, Bernhard.
An important approach to reducing persistent technical inefficiency is through technical change. This paper considers the case of genetically modified crop production. A stochastic frontier approach is used to examine how a drastic change from non-GM to GM technology effects the position of the production frontier as well as the extent and nature of technical inefficiency. A one-step method is applied to consider firm-level effects on technical inefficiency. Using soybean production from the U.S. we find that GM technology improves productivity and reduces technical inefficiency though these effects vary across farm characteristics.

REGULATORY FACTORS AFFECTING THE AGRI-FOOD BIOTECHNOLOGY SECTOR IN THE EUROPEAN UNION AgEcon
Diez, Maria Del Carmen Fernandez; Gil-Delgado, Maria De Los Reyes Corripio.
In Europe, in addition to public opposition to genetically modified food, the slow pace of development in agricultural and food biotechnology has been attributed to the lack of basic preconditions for commercial and innovative activities. The role and justification of a significant degree of regulation related to crop biotechnology is discussed. We try to clarify the existing broad structures which regulate these genetic technologies by focusing on several areas: environmental regulation, international trade, labelling and intellectual property rights. We attempt to involve the growing range of actors with different interests in the agri-food chain: biotechnology companies, the seed industry, farmer, and consumers. Finally, we discuss implications and...

Industry-Science Connections in Agriculture: Do public science collaborations and knowledge flows contribute to firm-level agricultural research productivity? AgEcon
Toole, Andrew A.; King, John L..
Prior research identifies a direct positive link between the stock of public scientific knowledge and agricultural productivity; however, an indirect contribution to agricultural productivity is also possible when this stock facilitates private sector invention. This study examines how “connectedness” between the stock of public scientific knowledge and private firms influences firm-level research productivity. Bibliographic information identifies the nature and degree to which firms use public agricultural science through citations and collaborations on scientific papers. Fixed effects models show that greater citations and collaborations with university researchers are associated with greater agricultural research productivity.

IS ONLINE GROCERY SHOPPING INCREASING IN STRENGTH? AgEcon
Corbett, James J..
Online grocery shopping is a relatively new innovation with regard to the way in which one purchases groceries. Some interesting concepts- designed to enhance the process of making grocery products available for consumption of the ever-changing consumer- have entered the food distribution industry channels. A telephone survey was conducted in the Boston trading area to determine the profile of online grocery consumers who are familiar with online grocery shopping.

Economic Growth in the Philippines: A Spatial Econometrics Analysis at the Provincial Level, 1991 – 2000. AgEcon
Pede, Valerien O.; Huelgas, Zenaida M.; Villano, Lorena; Garcia, Cornelia; McKinley, Justin D.; Mohanty, Samarendu.
Investigating the determinants of economic growth remains a long research tradition in the economic growth literature. Most studies in this literature have tried to link economic growth and different economic factors using either neoclassical growth theories or endogenous growth approaches. These studies apply these growth theories to identify the factors responsible for the observed differences/disparities between regions or countries. While early studies focused on cross-country analyses, the recent most studies consider regions or sub-national entities as unit of analysis. This has raised the question of whether theories developed for cross-country analysis could be automatically applied for regional or sub-national analysis. Given the profound...

Composition of the National Sheep Flock and Specification of Equilibrium Prices and Quantities for the Australian Sheep and Wool Industries, 2002-03 to 2004-05 AgEcon
Mounter, Stuart W.; Griffith, Garry R.; Piggott, Roley R.; Fleming, Euan M.; Zhao, Xueyan.
The data used, and the methods and assumptions fundamental to the development of an equilibrium displacement model (EDM) of the Australian sheep and wool industries specified in Mounter et al. (2007), are contained in this report. The national sheep flock is disaggregated into Merino and non-Merino sheep in the three agricultural zones of Australia using 2002-03 Australian agricultural and grazing industries survey data. Opening and closing sheep numbers, death rates and weaning percentages were used to derive the supply and use of sheep in each zone. Annual shorn wool production was split into four fibre-diameter categories in each zone corresponding to ABS wool export categories. Wool production percentages and relative greasy fleece weights were used to...

Do Energy Prices Induce Progress in Energy-Related Technology? An Empirical Study AgEcon
Schmitz, Simon.
Research efforts towards new energy sources and towards the efficiency of energy use will be vital to reducing CO2 abatement costs in the long term. Can such efforts be induced by price instruments? Economists often cite induced technological change as a possible consequence of environmental market-based policies. Unfortunately, however, there is not much empirical evidence about the policy-induced development of environmentally friendly technology. I use patent data from 1976 to 1997 for the US, Japan and the major European countries in order to estimate the effect of energy prices on energy-efficient innovations. A further supply factor with presumably positive influence in the model is an OECD measure of government R&D expenditures in different...

Identifying falsified clinical data AgEcon
Lee, Joanne; Judge, George G..
Clinical data serve as a necessary basis for medical decisions. Consequently, the importance of methods that help officials quickly identify human tampering of data cannot be underestimated. In this paper, we suggest Benford’s Law as a basis for objectively identifying the presence of experimenter distortions in the outcome of clinical research data. We test this tool on a clinical data set that contains falsified data and discuss the implications of using this and information-theoretic methods as a basis for identifying data manipulation and fraud.

Monsanto's Adventures in Zulu Land: Output and Labour Effects of GM Maize and Minimum Tillage AgEcon
Gouse, Marnus; Piesse, Jenifer; Thirtle, Colin G..
The only commercial genetically modified (GM) subsistence food crop is white maize in South Africa, which was released in 2001/2. This paper reports on the performance of insect resistant (Bt) white maize grown by smallholders in Hlabisa, KwaZulu Natal, where the other development is minimum tillage. The results show that, contrary to many inflated claims, in the dry 2003/4 season, there was no significant difference between the yield per kg of seed for Bt and conventional maize, due to very low stalk borer infestation levels. Farmers who planted Bt maize in 2003/2004 were thus worse off as they paid more for seed and obtained no benefit. This is measured using efficiency scores from a stochastic frontier analysis. These results conflict with the yield per...

Changing Food Purchasing and Consumption Habits among Urban Middle-Classes in Hyderabad AgEcon
Lohr, Kerstin; Dittrich, Christoph.
This preparatory case study provides an overview on the issue of changing food purchasing and food consumption habits among urban middle-classes in the South Indian emerging mega-city of Hyderabad. It analyses how food purchasing and dietary habits in this specific urban stratum are subject to profound changes due to increasing spending capacity and changing lifestyles in the context of economic liberalisation and globalisation processes. Another objective of the study examines health aspects of the changing food consumption habits. While nutrition research previously focused on the serious problem of undernutrition- related nutrient deficits, recent data shows that overweight and nutrition-related chronic diseases are more and more becoming serious...

AGRIBUSINESS: KNOWLEDGE AND INNOVATION PRIORITIES; ASPIRATIONS FOR THE 21ST CENTURY AgEcon
The present report presents the NRLO views on knowledge and innovation priorities for Dutch agribusiness in the years ahead as seen in an international perspective. Knowledge and innovation priorities are highlighted against the backdrop of key challenges facing Dutch agribusiness in the years to come. Major challenges include: To turn from reactive to proactive policy-making based on a broad range of values. The challenge facing agribusiness is that it should assume partial responsibility for maintaining and protecting ecological, cultural, ethical and spatial values. To transform agro-chains into responsive, flexible networks involving other sectors besides agribusiness (such as the transport and distribution sectors, non-food industries). To...

Underlying trends in employment-output equation: the case of Jordan AgEcon
Al-Rabbaie, Arqam; Alwaked, Ahmad; Altarawneh, Yaseen.
The underlying employment trend (UET) is investigated in Jordanian economy over the period 1989- 2004 using structural time series model (STSM). This approach allows to modelling the trend in its stochastic form introduced by Harvey (1989). The results show that a stochastic trend is preferred to deterministic trend. In addition, the inclusion or exclusion of the conventional deterministic trend leads to overestimated output elasticity. Furthermore, the UET is found to be non-linear, down downward sloping.
