Sustainable Management Of Groundwater In Louisiana, Dependra Bhatta

LSU Doctoral Dissertations

The common property nature of the Mississippi River Alluvial Aquifer (MRAA) results in the formation of a cone of depression in the southern portion of the aquifer encompassing Concordia parish, Louisiana. Excessive groundwater withdrawal and the resulting cone of depression formation have caused some wells to go dry and others to be affected by saltwater intrusion. The depleting groundwater stock can be managed optimally using different groundwater management policies. The findings of this dissertation are relevant to both policymakers and researchers to understand the effects of policies to keep the aquifer sustainable.

Seasonal Forecast Based Preharvest Hedging, Eric D. Hunt, Cory Walters, Toni Klemm, Iyore Eronmwon

Cornhusker Economics

Given the immense effect of weather on agriculture, skillful weather forecasts are of importance to agricultural producers for effective decision making. Weather forecasts affect operational decisions such as whether or not to irrigate (where applicable), when to apply fertilizer, when to spray herbicide and pesticide, and certainly the timing of planting and harvesting. At the seasonal time scale, say in the spring, just before planting, weather forecasts may be used for strategic decision making on outcomes, say from preharvest hedging (hereafter referred to hedging), that will not be realized until the fall or harvest. Historically, the lack of skill in …

Use Of Florpyrauxifen-Benzyl In Non-Flooded Rice Production Systems, Hannah Wright, Jason K. Norsworthy, Trenton L. Roberts, Robert C. Scott, Jarrod T. Hardke, Edward E. Gbur

Crop, Soil and Environmental Sciences Faculty Publications and Presentations

The lack of a flood on rice (Oryza sativa) levees and in furrow-irrigated rice creates a favorable environment for terrestrial weeds like Palmer amaranth (Amaranthus palmeri S. Wats) to emerge and quickly overtake the crop for a longer portion of the year than in flooded rice culture. Florpyrauxifen-benzyl is a new auxin herbicide labeled for use in rice that has activity on both grasses and broadleaf weeds, as well as certain sedges. Field experiments were conducted to determine the efficacy of florpyrauxifen-benzyl in a non-flooded environment. Experiments were conducted in 2017 and 2018 at the Lon Mann …

Presenting Smaller ‘Component Designs’ In Place Of Large Discrete Choice Experiment, Courtney Bir, Michael S. Delgado, Nicole Olynk Widmar

Department of Agricultural Economics Faculty Publications

Employing a sample of US residents, a new WTP (willingness-to-pay) data collection method using component discrete choice experiments is proposed and compared to the traditional method. The WTP experiments elicit consumer's WTP for potentially animal welfare improving production practices and product attributes in yogurt. The new data collection method was designed to decrease complexity by having respondents participate in fewer choice scenarios. Incidences of attribute non-attendance (ANA), a potential simplifying heuristic, occurred less frequently for all but one attribute in the new WTP data collection method. Exhibiting ANA for any attribute was negatively correlated with the time for completion.

The Economic Impacts Of Social Activism In Food Markets, Anubrata Deka, Emie Yiannaka, Konstantinos Giannakas

Cornhusker Economics

Private politics, usually led by nongovernmental organizations (NGOs) and social activists, focuses on changing the behavior of private economic agents through social pressure rather than through government action (although government action is also possible) (Baron, 2003). The food sector has been experiencing increased social pressure from social activist organizations to achieve diverse goals, ranging from improving food safety and food fortification to increasing transparency in food markets. A primary reason for the increase in organized activism in the food sector is the proliferation of the provision of credence attributes which are attributes unobservable through search or experience (consumption and use). …

Corruption And Cooperative Organizations, Konstantinos Giannakas, Murray E. Fulton

Cornhusker Economics

Although the literature is limited, there is evi-dence that corruption in cooperatives and inves-tor-owned firms (IOF) is widespread in develop-ing and transition economies where corruption generally is common. Cooperative corruption is also found closer to home. Two recent examples from the United States include the Ashby Farm-ers’ Cooperative Elevator in Minnesota where the general manager stole from the cooperative and the Tri-County Electric Cooperative in South Carolina where board members enriched them-selves with perks and benefits. In Canada, the PACE Credit Union was placed under the regula-tor’s control in 2018 after two senior executives were discovered to have received secret …

Dairy Product Purchasing In Households With And Without Children, Mario Ortez, Courtney Bir, Nicole Olynk Widmar, Jonathan Townsend

Department of Agricultural Economics Faculty Publications

Dairy products are considered a staple in the American diet due in part to their nutritious content and appealing flavor. Consumption patterns may differ among age segments influenced by preferences for fat content and taste in dairy. Furthermore, having children in their household may influence the amount, frequency, and type of dairy products that a consumer chooses to purchase. This study finds that households that frequently bought food for children generally purchased larger quantities of fluid milk and more fluid milk with a higher fat content. Households with children also bought yogurt more frequently than other households. Labeling information of …
