| Source-verified (SV) feeder cattle auctions were held in Bloomfield, Iowa, each October, November, and December from 1997-2000. This study compares price data from these SV auctions to traditional auctions at the same location to determine whether a premium exists for SV feeder cattle. Hedonic pricing models were estimated to evaluate the price effects of lot characteristics, market forces, and type of market (SV versus regular sale). The SV cattle were sorted and pooled into large lots. The larger lot size, consistent with early research, earned large price premiums. After accounting for lot size, the SV premium for lighter cattle (< 650/600-pound steers/heifers) was estimated at $1.30/cwt, and was significant. The SV premium over and above lot size... |

| In the United States (U.S.), there is no uniform traceability regulation across food sector. Food and Drug Administration (FDA) implemented one-step back and one-step forward traceability over the industries under its jurisdiction. U.S. Department of Agriculture (USDA), which oversees meat, poultry and egg production, requires some record keeping as part of food safety regulation. Particularly, a two-part-system has developed; live animal traceability and meat traceability with slaughter and processing plants in between. This paper studies the question of whether (and if so how) meat plants’ traceability levels vary with respect to the following factors; product specific (credence versus experience and search attributes, branded versus commodity meat,... |

| Participants in U.S. markets for live cattle increasingly rely on federal grading standards to price slaughtered animals. This change is due to the growing prominence of grid pricing mechanisms that specify explicit premiums and discounts contingent on an animal's graded quality class. Although there have been recent changes in the way cattle are priced, the technology for sorting animals into quality classes has changed very little: human graders visually inspect each slaughtered carcass and call a quality and yieldgrade in a matter of seconds as the carcass passes on a moving trolley. There is anecdotal evidence of systematic bias in these called grades across time and regions within U.S. markets, and this paper empirically examines whether such... |

| Participants in U.S. markets for live cattle increasingly rely on federal grading standards to price slaughtered animals. This change is due to the growing prominence of "grid" pricing mechanisms that specify explicit premiums and discounts contingent on an animal's graded quality class. Although these changes alter the way cattle are priced, the technology for sorting animals into quality classes has changed very little: human graders visually inspect each slaughtered carcass and call a "quality" and "yield" grade in a matter of seconds as the carcass passes on a moving trolley. There is anecdotal evidence of systematic bias in these called grades across time and regions within U.S. markets. We examine whether such claims are supported in a sample of... |

| Commingling cattle in the feedlot increases the odds of cattle getting sick. However, backgrounded cattle are less susceptible to diseases which allow the generalizing statements like "backgrounding is just like single source". Using data from over 15,000 cattle fed in 12 Iowa feedlots, we show that although backgrounded cattle do better than preconditioned cattle commingled in the feedlot, they have poorer carcass quality, health, and performance than single source cattle. Backgrounded cattle should be discounted $8.24/head relative to single source, and only received a small premium over multi-source preconditioned cattle though not significantly different. |

| Australia and New Zealand are major beef producing countries and major beef exporters. Unlike the case in the United States, where less than 10 percent of beef is exported, approximately 60 percent of Australia's and 85 percent of New Zealand's beef production is exported. Because of their dependency on a diverse set of export customers, these two countries are developing quality assurance programs that differentiate their beef in the global market and assure individual customers that the product is safe and meets customer needs. The Australian government and beef industry have invested in innovative identification, grading, and quality assurance systems that can be used by processors, producers, and supply chains. New Zealand relies upon individual... |

| The declining share of beef in total U.S. meat consumption has motivated industry-wide efforts to improve average beef quality through more effective coordination among the various market participants. Increased use of explicit "grid" pricing mechanisms over the last decade represent initial efforts at improved coordination. More recent efforts include animal-specific carcass data collection, with subsequent transmission to feeders and the relevant cow/calf operations, and improved "source verification" procedures aimed at (among other things) reducing the overall cost of medical treatment for live animals. None of these organizational innovations is costless, and indeed a number of significant barriers must be overcome before more widespread adoption of... |

| Conventional wisdom and earlier research have concluded that cattle feeding profitability is more determined by feeder and fed cattle prices than by animal performance. This study examined cross-sectional and time-series data from over 1600 pens of cattle in more than 220 feedlots in the upper Midwest where weather and lot conditions are thought to influence feedlot profitability. In addition to input and output prices and animal performance, other factors found to significantly impact cattle feeding profitability were sex, placement weight, facility design, and to a lesser extent placement season. |

| It has been argued that access to captive supply cattle improve the economic efficiency of beef packing facilities. However, this argument has not been subject to hypothesis testing. This work models the cost efficiencies associated with captive supplies or cattle we refer to as being sourced through alternative marketing agreements (AMAs). We find that slaughter and processing costs are lower ceteris paribus for AMA cattle than for cash market cattle. We find that plants that slaughter cattle from AMA sources operate at higher monthly volumes ceteris paribus and lower average costs per head. And we find that plants that slaughter cattle from AMA sources have more predictable volumes ceteris paribus and have lower average costs per head. If AMAs were... |
