Agricultural Sustainability and the Introduction of Genetically Modified Organisms (GMOs) AgEcon
Tisdell, Clement A..
In order to cater for the predicted growth in global population and aspirations for increased living standards, the world needs to increase substantially its level of agricultural production and sustain agriculture’s increased productivity. New technologies may enable this to occur but they also bring with them increased sustainability problems. There are many complex dimensions to achieving agricultural sustainability such as deciding on what agricultural attributes are worth sustaining and considering what trade-offs in objectives are required. These issues are discussed from a conceptual point of view. It is also shown using economic theory that market-based agriculture limits the opportunity for individual farmers to adopt sustainable agricultural...

Modeling Demand for Outdoor Recreation Settings with Choice Based Data Accounting for Exogenous and Endogenous Stratification AgEcon
Sardana, Kavita; Bowker, James Michael; Bergstrom, John C..
Estimating regional demand models by pooling different samples without correcting for such differences causes model misspecification as each sample belongs to a different population. Weighted regression using Pseudolikelihood to account for differences in sample population with adjustment for heteroskedasticity improves efficiency but the estimates are biased. We estimate regional demand for National Forest settings types in the southeastern states of U.S using weighted and unweighted regression. Using estimation of demand for National Forests as a case study, we resolve problems relating to inference about the data generating process when different samples are pooled together. We show that though efficiency of weighted estimates improves after correcting...

Rating the Web Sites of Land Grant Universities and State Departments of Agriculture AgEcon
Phillips, Jon C..
For at least ten years, educational and government organizations have used the Internet to communicate with their respective clienteles. Land grant universities, departments of agricultural economics, and state departments of agriculture have launched web sites to achieve various communication goals, including, among others: to disseminate research results, to generate positive publicity among various constituencies, to promote agricultural activities, and to recruit employees. This report is the result of an effort to systematically evaluate, rate, and comment on the web sites of land grant universities, departments of agricultural economics, and state departments of agriculture. A panel of reviewers rated the web sites of these organizations. The results...
