Factors Affecting Feedlots' Decisions On Cattle Marketing Options: A National Study, Charlotte Owusu-Smart Jan 2017

Factors Affecting Feedlots' Decisions On Cattle Marketing Options: A National Study, Charlotte Owusu-Smart

Electronic Theses and Dissertations

This thesis investigates the economic implication of changing slaughter volume patterns across the cash and contract markets in the US cattle industry. Weekly time series data that spans from November 2002 to December 2015 was used in the analysis. Empirical evidence suggests that Mandatory Price Reporting (MPR) played an important role in changing slaughter volumes across the cash and contract markets. Additionally, price of feeder cattle, cattle quality characteristics (Choice-Select spread and the percentage of animals grading choice or better) among others influence feedlots’ decision to use a particular marketing arrangement.


Heterogeneous Nitrogen Losses: Cost-Effectiveness Analysis Of Changes In Management Across South Dakota, Archibold Quaye Jan 2017

Heterogeneous Nitrogen Losses: Cost-Effectiveness Analysis Of Changes In Management Across South Dakota, Archibold Quaye

Electronic Theses and Dissertations

The loss of nitrogen fertilizer into the atmosphere and waterways is of increasing concern for citizens and policy makers. This is particularly relevant for hypoxia in rivers, lakes, and oceans, but also relevant for policy makers in reducing the increasing concentration of greenhouse gases (GHG) in the atmosphere. GHGs trap heat in the atmosphere and include: carbon dioxide, methane, nitrous oxide and fluorinated gases. Overall, the estimated contribution from the agricultural sector to GHG emissions was 9% in 2013 (EPA, 2013). Further, the addition of nitrogen to the soil through the use of synthetic fertilizers is a main contributor to …


Encouraging Organic Agriculture: The Effects Of Conversion Subsidies, Sarah Adams Inkoom Jan 2017

Encouraging Organic Agriculture: The Effects Of Conversion Subsidies, Sarah Adams Inkoom

Electronic Theses and Dissertations

This thesis examines the importance of conversional subsidies in accounting for an increase in organic acreage in the 12 North-Central States in the United States. Monthly time series data that spans from January 2002 to December 2014 was used in the analysis. Empirical evidence suggests that increase in organic acreage is due in part to the availability of conversion subsidies. Without government assistance, most small-scale farmers are not sufficiently motivated to switch to organic production due to the high initial costs involved in transitioning. Further, increased institutional support could facilitate organic adoption and its absence is detrimental to increasing the …


Performance Of The Producer Accumulator In Corn And Soybean Commodity Markets, Chad Te Slaa Jan 2017

Performance Of The Producer Accumulator In Corn And Soybean Commodity Markets, Chad Te Slaa

Electronic Theses and Dissertations

This research quantifies risk reduction and performance of the producer accumulator contract in corn and soybean markets. To quantify performance, we use three alternative theoretical pricing models to estimate historical producer accumulator contract specifications in corn and soybean markets. We then compare the performance of the producer accumulator to eight alternative agricultural marketing strategy portfolios that are also used in new generation grain contracts. The performance measures we compare are: average bushel price that would be received by the producer, daily portfolio risk, and the Sharpe ratio. The period we examine performance was between 2008 and 2017. We investigate performance …
