ECONOMIC RISK EFFICIENCY OF BOLL WEEVIL ERADICATION

The purpose of this study was to determine the economic risk efficiency of implementing a boll weevil (Anthonomus grandis [Boheman]) eradication (BWE) program in cotton (Gossypium hirsutum L.) producing regions of the Mississippi Delta. Alternative producer pest management practices and program cost sharing were incorporated into a biophysical cotton simulation model. Participation in a BWE program along with strict adherence to Cooperative Extension Service pest management guidelines proved to be the risk efficient practice.Crop Production/Industries, Risk and Uncertainty,

OPTIMAL AGRICULTURAL PEST MANAGEMENT WITH MULTIPLE SPECIES

Agricultural and Food Policy, Resource /Energy Economics and Policy,

Agriculture and the Environment in the European Union

Agricultural production in the European Union (EU) has increased dramatically since the early 1950’, but at a considerable environmental cost. Artificially high commodity prices maintained through the Common Agricultural Policy (CAP) have encouraged heavy investment in improved technologies and reinforced intensive use of such agricultural inputs as fertilizers and pesticides. Environmental degradation has included nitrate pollution of drinking water and loss of wildlife species. However, major reform of the CAP in May 1992 included direct payments to farmers, increased measures to limit production, and programs specifically designed to produce environmental benefits. Input use in U.S. agriculture is only a fraction of that in Europe and arable land area much more extensive. In the future, American farmers will face less severe tradeoffs between productivity and environmental preservation than their EU counterparts

Pesticide Residues and Food Safety: Aspects of a Changing Structure

In 1988, the Environmental Protection Agency administratively adopted a negligible risk or de minimis standard for registering pesticide uses in agriculture. The de minimis standard provides opportunity to lower the carcinogenic risk from pesticide residues in food. By providing a market for negligible risk pesticides, the new standard will likely allow reduction in use of the more hazardous compounds. Further, the new standard could lower food production costs if fewer uses of currently registered pesticides are banned. However, the agency's lack of data and safety margin procedures can potentially result in underestimates or overestimates of tumor risk. This report is based on papers and discussions at a Southern Agricultural Economics Association symposium in New Orleans in 1988

Integrated Pest Management, Anticipated Revision and Adaptive Control

Producers confronted with pest management problems must continually update information on the state of the crop, the level of pest infestation, and other factors to modify their conception of the evolving state. Determination of economic thresholds have at most been based on informational feedback systems that do not take into account possibilities for revision based on •the expected states of the crop system in future periods. This paper develops a framework for applying an adaptive control methodology to pest management decisions to fully consider both present and expected future information states. By incorporating anticipated revision of producers' decisions in an adaptive control scheme, it is expected that better production system performance can be realized

Sustainable Competitive Position of Mobile Communication Companies: Comprehensive Perspectives of Insiders and Outsiders

The identification of a sustainable competitive position in enterprises is a common concern of information science and sustainable development research. Achievement of sustainable competitive position and superior performance is the first priority of business organizations. However, the existing research focuses on technology competition and light market competition. The research proposes a comprehensive framework for identifying an enterprise’s sustainable competitive position based on a two-dimensional perspective of insiders (enterprise self-positioning) and outsiders (public cognition), including enterprise technology competition identification based on technology proximity, and enterprise market competition identification based on URL co-occurrence analysis. Based on the patents collected using the Derwent Innovation Index (DII) and the URL data collected from the Internet, the sustainable competitive position of mobile communication companies is identified from two dimensions of insiders and outsiders. QAP (quadratic assignment procedure) correlation analysis shows that these two dimensions are complementary. The two-dimensional perspective is integrated to comprehensively analyze the sustainable competitive position of Huawei, and thus obtain valuable information. In order to achieve the sustainability of competitive position in the industry, mobile communication enterprises must improve their management level (marketing characteristics of management and low cost structure), and must also have the ability to break through the governance system (rigid characteristics of governance) in a timely manner, and gain the ability to create value for customers in the long run (enhancement of public cognition and public image, and customer loyalty). Meanwhile, the mobile communication industry is a typical network externality market. If the companies want to obtain a sustainable competitive position in the competitive landscape, they need to manage user’s expectations, expand the foundation of users, achieve extensive cooperation and alliances with manufacturers of complementary products, and improve the quality and reputation of their brands
