Higher Carbon Prices Could Spur Adoption of Methane Digesters AgEcon
Key, Nigel D.; Sneeringer, Stacy E..
A market price for carbon emission reductions would allow livestock producers with methane digesters to earn additional revenue from trapping and burning methane from manure. Greater income from reducing methane emissions could substantially increase the number of livestock producers who would find it profitable to install methane digesters. Large-scale hog and dairy operations with lagoon manure management systems are likely to benefit most from a higher carbon price, which could have longrun structural implications for the livestock sector.

Effects of Clean Water Act Regulations on Firm-Level Decisions in Agriculture AgEcon
Sneeringer, Stacy E.; Key, Nigel D..
U.S. environmental regulations often vary by the size of the operation, with larger operations facing more regulatory stringency. When the size distribution of firms is heavily skewed, regulation size thresholds can reduce transaction costs for regulatory agencies while bringing most production within a regulatory framework. However, size-based regulation may have unintended consequences if operations downsize, slow their growth, or enter at a smaller size in order to avoid regulation. These unintended consequences from regulation may include less pollution abatement and diminished economic efficiency. In this study we examine recently revised Clean Water Act (CWA) regulations targeting large-scale livestock operations to identify and quantify farm...

Characteristics and Production Costs of U.S. Hog Farms, 2004 AgEcon
McBride, William D.; Key, Nigel D..
Hog production in 2004 was characterized by wide variation in the types, sizes, and economic performance of operations. Operations specializing in a single production phase generated more than three times the product value, on average, of those using the traditional farrow-to-finish approach. Low-cost operations tended to be larger, located in the Heartland, and operated by farmers whose primary occupation was farming. Small and medium operations far outnumbered large and very large operations, but large and very large operations accounted for most of the production. Average production costs declined as the size of the hog operation increased, a result of reduced capital costs and more efficient input use. Hog production was highly concentrated in the...

Changes in Manure Management in the Hog Sector AgEcon
Key, Nigel D.; McBride, William D.; Ribaudo, Marc.
In recent years, structural changes in the hog sector, including increasing farm size and regional shifts in production, have altered manure management practices. Over the same period, changes to the Clean Water Act, new state regulations, and increasing local conflicts over odor have influenced manure management decisions. This study uses data from two national surveys of hog farmers to examine how hog manure management practices vary with the scale of production and how these practices evolved between 1998 and 2004. The findings provide insights into the effects of structural changes and recent policies on manure management technologies and practices, the use of nutrient management plans, and manure application rates.

MANAGING MANURE TO IMPROVE AIR AND WATER QUALITY AgEcon
Aillery, Marcel P.; Gollehon, Noel R.; Johansson, Robert C.; Kaplan, Jonathan D.; Key, Nigel D.; Ribaudo, Marc.
Animal waste from confined animal feeding operations is a potential source of air and water quality degradation from evaporation of gases, runoff to surface water, and leaching to ground water. This report assesses the potential economic and environmental tradeoffs between water quality policies and air quality policies that require the animal agriculture sector to take potentially costly measures to abate pollution. A farm-level analysis of hog farms estimates the economic and environmental tradeoffs that occur when policies are designed to address pollutant flows to one environmental medium without considering flows to another medium. A national analysis addresses the broader impacts of coordinated (water and air) policies, including long-term structural...

Did the Baby Boom Cause the Farm-Size Boom? AgEcon
Roberts, Michael J.; Key, Nigel D..
Growing farm size has generally been explained by technological advances that have allowed farmers to substitute capital for labor. Another possible factor in explaining recent farm size is the demographic shift: the age distribution of farmers has shifted to the right and older farmers generally operate larger farms than younger farmers. This paper uses data from the 1982, 1987, 1992, 1997, and 2002 Agricultural Censuses to examine the relative importance of the demographic shift versus technological factors in explaining overall farm size growth. Results indicate that farm sizes tend to increase with age and that, holding age constant, the typical farm-size has increased over time for all ages, presumably due to technological change. The...

Carbon Emissions, Renewable Electricity and Profits: Comparing Alternative Policies to Promote Anaerobic Digesters on Dairies AgEcon
Key, Nigel D.; Sneeringer, Stacy E..
Biogas recovery systems that use methane from manure to generate electricity have not been widely adopted in U.S. mainly because the costs of constructing and maintaining these systems have exceeded the value of the benefits provided. Climate change mitigation and renewable energy policies could increase profits for the operators of such systems thereby making digester adoption more widespread. For the U.S. Dairy sector, we examine digester adoption rates, emissions reductions, net returns, electricity generation, and program costs under different policy scenarios. We find that 3% or fewer dairies would need to adopt digesters to meet the policy goals of reducing 25% of greenhouse gas emissions from dairy manure or generating one million megawatt hours...

Subsidies, production structure and technical change – A cross-country comparison AgEcon
Key, Nigel D.; Latruffe, Laure; Sauer, Johannes.
The effect of subsidies on production and technical change of crop farms in France and the United Kingdom (UK) during 1980-2006 is investigated. Subsidies were not neutral on production decisions, in terms of production intensity and type. Crop farms in both countries have experienced technical progress during the period studied, higher in France. Technical progress has favoured labour and chemicals in both countries, land in France, capital in the UK, while it has disfavoured land in the UK and capital in France. Technical change has been slowed down by crop area subsidies but increased by agri-environmental subsidies in both countries.
