Differences In The Determinants Of Retirement Preparation Between Farm And Nonfarm Households, Sheri L. Worthy, Travis Mountain, Swarn Chatterjee, Carrie Johnson, Elizabeth Kiss, Barbara O'Neill, Lorna Saboe-Wounded Head, Michael S. Gutter Feb 2021

Differences In The Determinants Of Retirement Preparation Between Farm And Nonfarm Households, Sheri L. Worthy, Travis Mountain, Swarn Chatterjee, Carrie Johnson, Elizabeth Kiss, Barbara O'Neill, Lorna Saboe-Wounded Head, Michael S. Gutter

Journal of Applied Farm Economics

As principal farm operators age, retirement and succession planning has become increasingly important to the U.S. agriculture industry. This study examined differences in the determinants of retirement preparation between farm and nonfarm households using the Survey of Consumer Finances. Factors such as risk preferences, financial capability, human capital, and other demographic characteristics of farmers that may play a role in their decision to plan for retirement were examined. Retirement planning was investigated by running three separate sets of logistic regressions on the overall sample, farm households, and nonfarm households. Likelihood of consulting a financial planner, expecting to leave a bequest, …

Cost Efficiency Of International Corn And Soybean Production, Rachel Purdy, Michael Langemeier Feb 2021

Cost Efficiency Of International Corn And Soybean Production, Rachel Purdy, Michael Langemeier

Journal of Applied Farm Economics

The objective of this paper was to examine the cost efficiency of corn and soybean pro-duction for typical farms involved in the cash crop agri benchmark network using data for the period 2013 to 2017. Average cost efficiency for the typical farms in the network that produced corn, soybeans, and both corn and soybeans was 0.749, 0.774, and 0.939, respectively. Inefficiency was a greater problem for the farms producing corn than for the other farm types examined. Inefficient farms tended to overutilize direct, operating, and overhead inputs.

Bred Heifer Price Determinants In The Southeast, Christopher Boyer, Andrew P. Griffith, Jada M. Thompson, Justin Rhinehart, Kenneth H. Burdine, Kevin Laurent Feb 2021

Bred Heifer Price Determinants In The Southeast, Christopher Boyer, Andrew P. Griffith, Jada M. Thompson, Justin Rhinehart, Kenneth H. Burdine, Kevin Laurent

Journal of Applied Farm Economics

Price determinants for bulls, cows, and feeder cattle are well established in the literature but there has been little research on bred heifer price determinants and specifically the impact of feeder cattle prices on the purchase price of bred heifers. We estimated the impact of reproductive characteristics and feeder cattle prices on bred heifer prices for beef production. Data were obtained from a May and November bred heifer sale located in Kentucky and hedonic pricing models were estimated for bred heifers for each sale month. Prices for fall- calving heifers were influenced by number of months bred or expected calving …

Determinants Of Feedlot Cattle Death Loss Rates, Mark Buda, Kellie Curry Raper, John Michael Riley, Derrell S. Peel Feb 2021

Determinants Of Feedlot Cattle Death Loss Rates, Mark Buda, Kellie Curry Raper, John Michael Riley, Derrell S. Peel

Journal of Applied Farm Economics

Death loss in feedlot cattle can have significant impacts on feedlot profitability. Not only does death loss result in foregone revenue, but the operation still incurs the costs to date associated with those animals. This study uses pen-level feedlot data from a private feed-lot in the Southern Great Plains. Both company- owned and customer retained ownership cattle are included in the data set. A Tobit model is used to analyze pen characteristics’ influence on death loss in feedlot cattle, including cattle characteristics, source characteristics, management characteristics, and treatment incidence. Results imply that several pen characteristics impact death loss and that …

Reflections On Service With Ace Campus Food Pantry, Marly Beck Oct 2020

Reflections On Service With Ace Campus Food Pantry, Marly Beck

Purdue Journal of Service-Learning and International Engagement

In 2018, the HOPE Lab reported that 36% of four-year university students were food insecure at least once in the previous month. This has been associated with a shifting U.S. undergraduate population and the rise in associated costs of college. The consequences of hunger can manifest negatively through a student’s performance inside the classroom; it is also associated with student anxiety and depression. At Purdue, the primary resource for individuals experiencing food insecurity is the ACE Campus Food Pantry, which serves faculty, staff, undergraduate, and graduate students. A group of student leaders direct the pantry with advising from the Center …

Farm Management Practices Used By Wheat Producers In The Western Great Plains: Estimating Their Productivity And Profitability, Jeffrey Vitale, Pilja Park Vitale, Francis Epplin, Kris Giles, Norm Elliott, Frank Peairs, Paul Burgener, Sean Keenan, Gerald Michels, Gary Hein Apr 2020

Farm Management Practices Used By Wheat Producers In The Western Great Plains: Estimating Their Productivity And Profitability, Jeffrey Vitale, Pilja Park Vitale, Francis Epplin, Kris Giles, Norm Elliott, Frank Peairs, Paul Burgener, Sean Keenan, Gerald Michels, Gary Hein

Journal of Applied Farm Economics

Changes in government farm programs and the introduction of new technology offer wheat producers in the western Great Plains a variety of management practices to alleviate biotic and agronomic constraints inherent in a wheat monoculture. Producers have adopted alternative tillage systems, crop diversification, and insect-resistant varieties in response to the hot, semiarid growing conditions and increased pest pressure. The objective of this study was to determine if those practices generated positive impacts on wheat yield and corresponding net returns. Panel data collected from a group of 141 producers over a four-year period (N = 564) were analyzed using econometric models. …

Improving Beef Cattle Profitability By Changing Calving Season Length, Christopher N. Boyer, Andrew P. Griffith, Ky G. Pohler Apr 2020

Improving Beef Cattle Profitability By Changing Calving Season Length, Christopher N. Boyer, Andrew P. Griffith, Ky G. Pohler

Journal of Applied Farm Economics

We determined the impacts of calving season length on net returns and variability in net returns for spring-and fall-calving herds in Tennessee. Weaning weight as a function of calving date was estimated using a 19-year data set and simulation models generated distributions of net returns for 45-, 60-, and 90-day calving periods with and without using hypothetical improved reproductive management (IRM) practices. Shortening the calving period from 90 days increased expected net returns in the spring-and fall-calving herds. The 45-day fall-calving period with IRM maximized profits, but an extremely risk-averse producer would select a 45-day fall-calving period without IRM.

Financial Implications From Contracting Avian Influenza In A U.S. Broiler Operation, Jordan M. Shockley, Tyler Mark, Kenneth H. Burdine, Levi Russell Apr 2020

Financial Implications From Contracting Avian Influenza In A U.S. Broiler Operation, Jordan M. Shockley, Tyler Mark, Kenneth H. Burdine, Levi Russell

Journal of Applied Farm Economics

This essay evaluates the on-farm financial impacts of an avian influenza outbreak on a U.S. commercial broiler operation. It investigates how the timing and length of the outbreak impacts farm financial performance for two different farmers, beginning and experienced. Results indicate that a beginning farmer is more susceptible to significant financial losses. Both farmers are financially impacted more when avian influenza is contracted early in the investment and when the contamination and eradication of the virus was prolonged. Furthermore, this essay highlights the problems of using standard financial measures for analyzing disease outbreaks under production contract arrangements and presents alternative …

Annual Net Returns To Cover Crops In Iowa, Alejandro Plastina, Fangge Liu, Wendiam Sawadgo, Fernando E. Miguez, Sarah Carlson, Guillermo Marcillo Nov 2018

Annual Net Returns To Cover Crops In Iowa, Alejandro Plastina, Fangge Liu, Wendiam Sawadgo, Fernando E. Miguez, Sarah Carlson, Guillermo Marcillo

Journal of Applied Farm Economics

Despite the active promotion of cover crops as a key conservation practice, their adoption is very limited. We developed a series of partial budgets based on a statewide survey of Iowa farmers to evaluate the changes in net returns resulting from the incorporation of cover crops into a corn or soybean production system. The average net returns to cover crop use for farmers who did not use cover crops for grazing livestock or forage were consistently negative across different planting and termination methods, tillage practices, and experience levels. Only farmers who used cover crops for grazing livestock or forage and …

Including Fossil-Fuel Consumption Subsidies In The Gtap Data Base, Maksym Chepeliev, Robert Mcdougall, Dominique Van Der Mensbrugghe Jun 2018

Including Fossil-Fuel Consumption Subsidies In The Gtap Data Base, Maksym Chepeliev, Robert Mcdougall, Dominique Van Der Mensbrugghe

Department of Agricultural Economics Faculty Publications

Historically fossil-fuel consumption subsidies have been one of the most widely used energy and public policy interventions. According to the International Energy Agency (IEA), in 2014 they amounted to $493 billion worldwide, which is equivalent to 0.6% of global GDP. Their contribution is even more significant for most energy exporting countries, in many cases exceeding 5-15% of national GDP. However, despite their large magnitude, fossil-fuel consumption subsidies are not explicitly represented in most global economic databases and models, including the Global Trade Analysis Project (GTAP) Data Base, as they are generally not captured by the input-output framework. In this paper, …

Economic Impact Of Beef Cattle Best Management Practices In South Texas: Stocking Strategies During Drought, Alan M. Young, Megan K. Clayton, Joe C. Paschal, Steven L. Klose May 2018

Economic Impact Of Beef Cattle Best Management Practices In South Texas: Stocking Strategies During Drought, Alan M. Young, Megan K. Clayton, Joe C. Paschal, Steven L. Klose

Journal of Applied Farm Economics

In a drought situation, forage is normally reduced due to lack of adequate moisture. Moreover, the availability of hay may become limited, and hay prices often escalate. Cow-calf producers are faced with the integral decision to maintain their herds and supplemental feed or reduce the herd to minimize feeding requirements and costs. The management decision to maintain versus destock can significantly impact producer profits and financial position. This paper illustrates the financial implications of alternative management stocking strategies in a drought situation optimizing profitability of ranching operations.

Demographic Influences On Nonadoption Of Calf Management And Marketing Practices For Cow-Calf Operations, Stephanie Schumacher, Derrell S. Peel, Kellie Curry Raper Oct 2017

Demographic Influences On Nonadoption Of Calf Management And Marketing Practices For Cow-Calf Operations, Stephanie Schumacher, Derrell S. Peel, Kellie Curry Raper

Journal of Applied Farm Economics

Though research indicates that many calf management and marketing practices are available to add value for the cow-calf producer, a high percentage of producers are still nonadopters of such practices. Little information identifies nonadopters in the beef cattle industry, limiting efforts to provide educational support. This study uses a binomial logit model and primary survey data to examine the demographic influence on producers’ nonadoption of commonly recommended value-added management and marketing practices specific to feeder calves in the cow-calf segment.

Short-Term Asset And Debt Choice And U.S. Corn Farm Liquidity, Sarah Stutzman, Todd Hubbs Oct 2017

Short-Term Asset And Debt Choice And U.S. Corn Farm Liquidity, Sarah Stutzman, Todd Hubbs

Journal of Applied Farm Economics

The liquidity positions of U.S. corn farms over the period 2002–2013 is examined using Agricultural Resource Management Survey (ARMS) data and calculating the average annual working capital to gross revenue (WC/GR) ratio for farms within the 25th percentile, median, and 75th percentile. The relationship between liquidity and land ownership, farm size, and the composition and level of short-term farm asset and debts by category are compared across farms within the 25th, 25th–75th, and 75th WC/GR ratio percentile. We find that, on average, farms in the 75th WC/GR ratio percentile owned a greater portion of their operated acres and maintained both …

Price Relationships Between Calves And Yearlings: An Updated Structural Change Assessment, Glynn T. Tonsor, Emily Mollohan Apr 2017

Price Relationships Between Calves And Yearlings: An Updated Structural Change Assessment, Glynn T. Tonsor, Emily Mollohan

Journal of Applied Farm Economics

This article updates and extends the understanding of U.S. feeder cattle price determinants. Structural change in the summer of 2008 was identified, with both calf and yearling markets adjusting to become substantially more sensitive to changes in corn and expected live cattle prices. The impact of live cattle price expectations on feeder cattle prices is three or more times larger than the same proportional impact of corn price, and this relative impact has increased since 2008. Price spreads between calves and yearlings are also found to be more sensitive to input and output price changes than individual cattle price series. …

Economic Viability Of Flexible Biogas Pumps In Bangladesh, Saima A. Matin Aug 2016

Economic Viability Of Flexible Biogas Pumps In Bangladesh, Saima A. Matin

Open Access Theses

This study examines the economic viability of flexible irrigation pumps that can run on biogas as well as diesel fuel in Bangladesh. Such examination faces two main hurdles. First, the ease with which farmers running flexible pumps can switch from one energy source to another is unknown and perhaps highly heterogeneous. Second, diesel prices in Bangladesh are volatile and limited information precludes direct estimation of their probability distribution. We address the first issue by evaluating the economics of flexible pumps for varying degrees of inter-fuel substitutability. To deal with the second issue, we model the probability distribution of Bangladeshi diesel …
