Price Impacts Associated With The Closing Of Hog Slaughtering Plants, Marvin Hayenga, Ronald Deiter, Cristobal Montoya 2017 Iowa State University

Price Impacts Associated With The Closing Of Hog Slaughtering Plants, Marvin Hayenga, Ronald Deiter, Cristobal Montoya

Ronald Deiter

The impact of closing hog slaughtering plants is examined by comparing relative prices in affected local market areas with prices in distant markets before and after a plant closed. The results suggest that market arbitrage usually has been quite effective, with either temporary or insignificant price effects in six case studies.


Capacity Management In Agricultural Commodity Processing And Application In The Palm Industry, Onur BOYABATLI, Quang (Jason) Dang NGUYEN, Tong WANG 2017 Singapore Management University

Capacity Management In Agricultural Commodity Processing And Application In The Palm Industry, Onur Boyabatli, Quang (Jason) Dang Nguyen, Tong Wang

Research Collection Lee Kong Chian School Of Business

This paper examines the capacity investment decisions of a processor that uses a commodity input to produce both a commodity output and a byproduct in the context of agricultural industries. We employ a multi-period model to study the optimal one-time processing and (output) storage capacity investment decisions---in addition to the periodic processing and inventory decisions---when both input and output spot prices as well as production yield are uncertain. We characterize the optimal decisions and perform sensitivity analysis to investigate how spot price uncertainty affects the processor's optimal capacity and profitability. Using a calibration based on the palm industry, we ...

Scale, Organization, And Profitability Of Ethanol Processing, Paul Gallagher, Hosein Shapouri, Heather Brubaker 2016 Iowa State University

Scale, Organization, And Profitability Of Ethanol Processing, Paul Gallagher, Hosein Shapouri, Heather Brubaker

Paul Gallagher

We analyze the appropriate size and implied profitability of a representative ethanol processing firm. An analysis based on current processing technology and costs with typical conditions in Iowa product and input markets is useful; because unit production costs have declined 30% in current dollars over the last 15 years; and because discovering a suitable size for processing facilities has been an important part of the cost-reducing process. We apply theoretical plant size rules for a conventional processing business, an integrated producer/processor enterprise, and a processing cooperative. We also introduce a spatial dimension for the corn input market, because ethanol ...


The International Competitiveness Of The U.S. Corn-Ethanol Industry: A Comparison With Sugar-Ethanol Processing In Brazil, Paul Gallagher, Guenter Schamel, Hosein Shapouri, Heather Brubaker 2016 Iowa State University

The International Competitiveness Of The U.S. Corn-Ethanol Industry: A Comparison With Sugar-Ethanol Processing In Brazil, Paul Gallagher, Guenter Schamel, Hosein Shapouri, Heather Brubaker

Paul Gallagher

An indicator of competitive position, the cost difference between ethanol import from Brazil with sugar processing and domestic production with corn in the United States under ideal conditions without tariffs in the ethanol market, is developed conceptually. An ex ante version of the indicator that is based on historical prices and today's technology is calculated for the last 30 years and subjected to time series analysis. Results suggest that there are no trends, but there are cyclical periods of advantage for both industries. Further, long-term averages suggest that profits would be similar in both countries under ideal trade conditions ...


A New Brand Of Agriculture? Farmer-Owned Brands Reward Innovation, Dermot J. Hayes, Sergio H. Lence 2016 Iowa State University

A New Brand Of Agriculture? Farmer-Owned Brands Reward Innovation, Dermot J. Hayes, Sergio H. Lence

Dermot J. Hayes

Commodity agriculture as currently practiced in the U.S. Midwest is an extremely efficient way of organizing production and distribution. It allows for inexpensive production and bulk transfer of huge quantities of meat and grain and has resulted in enormous cost savings to U.S. and international consumers. This system has evolved in accordance with market forces, and we expect that these same forces will allow the current system to survive for decades.

Economic Perspectives On Gmo Market Segregation, John A. Miranowski, Giancarlo Moschini, Bruce Babcock, Michael Duffy, Robert Wisner, John C. Beghin, Dermot J. Hayes, Sergio H. Lence, C. Phillip Baumel, Neil E. Harl

Dermot J. Hayes

Genetically modified .organisms (GMO) crops have become increasingly popular with Iowa farmers over the past few,years. The current genetic modifications are focused on pest management technologies. Although there were early efforts by environmental activists to disrupt the adoption of GMO technology, few concerns were raised by U.S. food retailers and consumers., The primary concern was getting European Union (EU) regulatory-approval for each GMO crop variety event as late as spring 1999. The situation has changed dramatically in the last few months, and the current situation is highly uncertain. .

Supply, Land Quality, And Policy, Paul Gallagher 2016 Iowa State University

Supply, Land Quality, And Policy, Paul Gallagher

Paul Gallagher

Recent reforms of the EC grain sector justify renewed interest in the supply ^alysis of producer policies that include a subsidy and a land reduction requirement. Some supply analysis accounts for simultaneous land control and producer payment (Houck and Ryan, Gallagher). However, econometric methods of supply analysis have limited usefulness when major policy changes occur (Weaver). Major changes have indeed occurred in Europe, 1. CAP reform, introducing producer subsidies, low ?? price and set-aside. 2, Transition from central planning. But land quality is an important dimension of producer's participation decisions (Brooks et al.). And the implications of producers with marginal ...


A Review Of Perspectives And Policies On Food Security, Paul Gallagher 2016 Iowa State University

A Review Of Perspectives And Policies On Food Security, Paul Gallagher

Paul Gallagher

There are only two parts of the developing world where a massive problem of food insecurity exists, namely South Asia and Subsaharan Africa. This is where a major portion of the poor in the world reside. Increased attention to the developments in Eastern Europe and the Soviet Union have however diverted attention from the problems of this poor humanity. The likely short term adverse effects of the proposed reduction in protection of the US and the EEC agriculture on the food importing developing countries through the increased cost of food imports has also not received the attention that it deserves ...


Labor Markets, Human Capital, And The Human Agent's Share Of Production, Wallace E. Huffman 2016 Iowa State University

Labor Markets, Human Capital, And The Human Agent's Share Of Production, Wallace E. Huffman

Wallace Huffman

Labor, or the time of the human agent, is one of the most important inputs in production. Labor services in agriculture are provided: by farm operators/ managers who perform very important allocative, production/marketing decision making and supervisory functions (Schultz 1972; Huf&nan 1985; Huffman 199lb) and frequently engage directly in production; by members of the operator's family or relatives who largely work without direct compensation; and by hired workers. The incomes of farm families and of hired farm workers are determined not only by the amount of labor that they sell but also by the amount of other resources to ...


Econometric Modeling Of The Public Grazing Fee's Impact On The U.S. Sheep Industry, Ryan C. Feuz 2016 Utah State University

Econometric Modeling Of The Public Grazing Fee's Impact On The U.S. Sheep Industry, Ryan C. Feuz

All Graduate Plan B and other Reports

The U.S. sheep and wool industry is one of the oldest agricultural industries within the country. Since the mid 1940’s the industry has witnessed dramatic annual declines in sheep inventories. Many factors have contributed to the decline of the sheep industry including declining consumption of lamb and mutton, the growth in man-made fiber use, scarcity of labor, and predator losses. The U.S. congress has attempted to slow this decline throughout the years with various policy including the use of wool marketing loan programs. Such programs are intended to help bring stability as well as to mitigate price ...


The Demand For Agricultural Research By State Governments, Jyoti Khanna, Wallace E. Huffman, Todd Sandler 2016 Iowa State University

The Demand For Agricultural Research By State Governments, Jyoti Khanna, Wallace E. Huffman, Todd Sandler

Wallace Huffman

Public agricultural research in the United States is conducted by state agricultural experiment stations (SAES) and by the research agencies of the USDA. Both have research activities in every state. A vast amount of research and experiments has shown that the performance of plants and to a lesser extent animals, in which new technologies are frequently embodied, is altered by local geoclimatic conditions that differ within and between states. Basic research and livestock research to some extent lead to new knowledge or technologies that spill widely across state boundaries. Thus, public agricultural research produces knowledge that is both state specific ...


Public R&D, Private R&D, And U.S. Agricultural Productivity Growth: Dynamic And Long-Run Relationships, Sun Ling Wang, Paul W. Heisey, Wallace E. Huffman, Keith O. Fuglie 2016 United States Department of Agriculture

Public R&D, Private R&D, And U.S. Agricultural Productivity Growth: Dynamic And Long-Run Relationships, Sun Ling Wang, Paul W. Heisey, Wallace E. Huffman, Keith O. Fuglie

Wallace Huffman

If accelerated productivity growth is to be an effective policy response for reducing greenhouse gas emissions from agriculture, the appropriate means for raising productivity needs to be addressed. Previous research has shown a close correlation between investments in public agricultural research and total factor productivity (TFP) growth in agriculture (Huffman and Evenson 2006; Alston et al. 2010; Wang et al. 2012, among the most recent, comprehensive studies). Largely neglected from this framework, however, has been the role of the private sector. Private sector spending on agricultural research and development (R&D) has grown more rapidly than public agricultural R&D ...


Economics Of Intellectual Property Rights In Plant Materials, Wallace Huffman 2016 Iowa State University

Economics Of Intellectual Property Rights In Plant Materials, Wallace Huffman

Wallace Huffman

This paper presents an economic perspective on intellectual property in plant materials, including its value, and summary information on the U.S. seed industry. It first considers intellectual property rights--types, economic incentives that they bestow, and uses across developed and developing countries. Second, it considers the U.S. seed industry-- characteristics for major crops, optimal pricing of a superior variety, and relative size of public and private research expenditures. Some conclusions and implications are presented in the final section.

Estimating The Public Value Of Conflicting Information: The Case Of Genetically Modified Foods, Matthew C. Rousu, Wallace E. Huffman, Jason F. Shogren, Abebayehu Tegene

Wallace Huffman

Environmental groups have become the chief antagonists toward agricultural biotechnology innovations. They demonstrate and disseminate private information with the objective of changing the behavior of consumers and producers. We use experimental auctions with adult U.S. consumers and show that this information reduces significantly the demand for genetically modified (GM)-food products and that it has significant public good value—an average of 3 cents per product purchased, or roughly $2 billion annually. We also show that the dissemination of independent third-party information about agricultural biotechnology dissipates most of the public good value of negative GM-product information.


Photovoltaic Cooking In The Developing World, Tyler Watkins, Christopher O'Day, Omar Arriaga 2016 California Polytechnic State University, San Luis Obispo

Photovoltaic Cooking In The Developing World, Tyler Watkins, Christopher O'Day, Omar Arriaga

Mechanical Engineering

The challenge of clean cooking is faced by hundreds of millions of people worldwide. We present a cooking technology consisting of a solar panel directly connected to an electric heater in a well-insulated chamber. Assuming continued decrease in solar panel prices, we anticipate that in a few decades Solar Electric Cooking technologies will be the most common cooking technology for the poor. Appropriate use of insulation reduces the power demand making low-power Insulated Solar Electric Cooking systems already cost competitive.


An Economic Evaluation Of A Biofuel Supply Chain Utilizing Multiple Feedstocks, Huaqi Zhang 2016 University of Tennessee, Knoxville

An Economic Evaluation Of A Biofuel Supply Chain Utilizing Multiple Feedstocks, Huaqi Zhang

Masters Theses

Biomass is considered as one potential feedstock for biofuel production. However, the high cost of biomass-to-biofuel supply chain, attributed to biomass’s low bulk density and resulting harvest, storage, and transportation challenges, has been a major hindrance to the success of biomass-based biofuel industry. In addition, the issue of dry matter losses during storage for a feedstock has affected biomass quantity and quality if the feedstock is stored for several months after a single harvest in a year. One potential way to improve the economics of biomass supply chain is to reduce storage need and enhance the utilization of harvest ...


A Test For Complementarities Among Multiple Technologies That Avoids The Curse Of Dimensionality, Li Yu, Terrance Hurley, James Kliebenstein, Peter F. Orazem 2016 Central University of Finance and Economics

A Test For Complementarities Among Multiple Technologies That Avoids The Curse Of Dimensionality, Li Yu, Terrance Hurley, James Kliebenstein, Peter F. Orazem

Peter Orazem

We propose a strategy to identify the complementarity or substitutability among technology bundles. Differences between the observed distribution of technology choices can be subjected to statistical tests. Combinations of technologies that occur with greater frequency than would occur under independence are complementary technologies. Combinations that occur with less frequency are substitute technologies. We use the strategy to evaluate multiple technology adoptions on US hog farms. As the number of bundled technologies increases, they are increasingly likely to be complementary with one another, even if subsets are substitutes when viewed in isolation.


Comparison Of Four Harvesting Systems In A Loblolly Pine Plantation, John Klepac, Dana Mitchell 2016 USDA Forest Service, Southern Research Station

Comparison Of Four Harvesting Systems In A Loblolly Pine Plantation, John Klepac, Dana Mitchell

Professional Agricultural Workers Journal

Abstract

Felling and skidding operations were monitored while clearcut harvesting a 12-acre area of a 14-year old loblolly pine (Pinus taeda) plantation. The study area contained 465 trees per acre for trees 2.0 inches Diameter at Breast Height (DBH) and larger with a Quadratic Mean Diameter (QMD) of 7.26 inches. Two feller-bunchers (tracked and rubber-tired) and two skidders (conventional and large capacity) were paired to create four different harvesting systems which were randomly assigned to 3-acre units for evaluation of production rates and costs. Each system was balanced to determine the number of machines needed to minimize the ...
