The theory of factor market distortions deals largely with taxing inputs. However, input subsidies are not only common in manufacturing. For example, U.S. agriculture is heavily dependent on input subsidies.
If water subsidies in the production of California cotton were removed, along with commodity payments, production of cotton in California would likely cease. Likewise, transportation subsidies were common in both the U.S. and Canada, and still prevail in the U.S.

The economic theories of New Institutional Economics, auctions, and welfare economics are used to analyze the potential for E-Commerce as an institution within the agricultural sector. We discuss the theory of the firm within the NIE paradigm and focus on the potential for E-Commerce to reduce transaction costs, search costs, and the costs associated with buying and selling livestock under various auction formats. We develop a theoretical model that captures the effect of Internet feeder-cattle auctions on Florida’s cattle market at three different levels in the marketing channel. We discuss the institutional arrangements and marketing mechanisms associated with the marketing of stocker and feeder cattle in Florida. We present the results of a survey distributed to cattle producers in North Florida regarding herd size, direct transaction costs of marketing cattle, and the implications of internet technology. Finally, we perform an empirical welfare analysis in order to estimate the impact of reduced transaction costs associated with Internet and video livestock auctions on cow-calf operators and backgrounders in Florida.

We investigate the underlying reasons for producers’ choice of marketing channels for stocker cattle in the United States. In addition to traditional public auctions, private sales, video auctions, and Internet auctions have been recently used in the marketing of stocker cattle. We find that while the number of marketing options may have increased in recent years, only relatively large producers can actually take advantage of these options. The marketing options for smaller producers are still limited due to their relative size. We also find that the number of cattle marketed privately and through video and Internet auctions is positively correlated with herd size. In addition, the New Institutional Economics provides insights into how herd size influences the choice of marketing channels.

We compare the current Canadian Supply Management regime in which producers and importers benefit from rent-seeking activities that set production quota and import quota levels with those under a tariff, in which producers partakes in rent-seeking activities in order to induce the government to introduce a favorable tariff regime. We explore three different quota-setting games: (1) the import quota and production quota are set at a level that arises from a Cournot-Nash equilibrium between producers and importers; (2) the producer marketing board acts as a Stackelberg leader, taking into account the importers’ reaction to its production quota level; and (3) the importer behaves as a Stackelberg leader, taking into account producers’ reaction to its import quota level. We compare these quota-setting games with two different tariff-setting games: (1) A non-cooperative game in which the government sets the tariff at a level that maximizes tariff revenue; and (2) A cooperative game in which producers, through rent-seeking activities, induce the government to set the tariff at a level that maximizes joint government and producer rents.

A massive pile of wood debris caught fire and burned from October 27 to October 31, 2001, in northern Pinal County, Arizona. The fire consumed wood debris from citrus trees that had been stored in an approximately 25-acre area in Pinal County near the Queen Creek area. The fire generated a large quantity of smoke. Persons reported smelling the smoke up to 40 miles away from the fire. Meteorological conditions during the fire intermittently created conditions that limited lift, especially at night, causing smoke to settle in residential neighborhoods in the Queen Creek area. The Arizona Department of Health Services issued public health advisories for the evenings of October 29 and 30. This report summarizes the events that occurred during the fire and analyzes the data collected by the Arizona Department of Health Services and the Arizona Department of Environmental Quality to determine the extent of the public health threat from the fire.

The Rodeo-Chediski Fire Complex began as a small blaze in a remote region of east-central Arizona and within days erupted into the largest wildfire in Arizona history. Fortunately, no lives were lost. However, from June 18, 2002 to the time of its containment on July 7, 2002, the Rodeo-Chediski fire destroyed over 490 structures and 467,000 acres of ponderosa pine and pinyon-juniper woodland—an estimated 500 million to 1.3 billion board feet of timber. Jurisdictions involved included the Fort Apache Indian Reservation, the Apache-Sitgreaves National Forest, the Tonto National Forest, and private lands adjacent to Highway 260, from the Town of Forest Lakes east to the City of Show Low. Virtually all of the acres burned were in Navajo County, with some damage in the contiguous counties of Coconino, Apache, and Gila Counties. This health assessment describes the fire events and summarizes the resulting public health impacts from the fire.

The Arizona Department of Health Services Cancer Registry has identified 7 cases of childhood leukemia in the Sierra Vista, Arizona area since 1995. Five of the childhood leukemia cases were identified as a class of lymphoid leukemia and 2 of the cases were a class of myeloid leukemia. Based on random variation, a total of 6 or fewer cases of leukemia would have been expected over those seven years. An analysis of the data suggests that the number of cases is statistically elevated for the time period 1995 to 2001. The objective of this report is to determine whether there are any documented environmental exposures from drinking water, ambient air or waste sites that may have placed residents of the Sierra Vista, Arizona area at greater risk of developing childhood leukemia.

The Arizona Department of Health Services completed this health consultation at the request of the Arizona Department of Environmental Quality. This consult evaluates whether soil vapors from volatile organic compounds in the subsurface near the Silver Creek Subdivision in Tucson, Arizona are present at levels that may cause adverse health effects.

The Agency for Toxic Substances and Disease Registry has asked the Arizona Department of Health Services, Office of Environmental Health, to conduct a health assessment for the off-site residential area located adjacent to the Tucson Industrial Center, also known as the 3 Hangars site, within the larger Tucson International Airport Area Superfund site, in Tucson, Arizona. Previous investigations found that elevated levels of polychlorinated biphenyls (PCBs) in the drainage areas at the TIC site had migrated off-site into residential areas presenting a health threat to residents. The purpose of this Public Health Assessment is to evaluate if a public health hazard still exists since the remediation activities have been conducted at the off-site El Vado residential area. ADHS concludes that no current public health hazard exists as a result of ingestion, dermal, or inhalation exposures by residents, children, or transients to the post remediated soil in the residential areas on El Vado Road. Replacement of the top soil with certified clean soil has removed all contact with the soil containing PCBs eliminating any future public health hazard.

The United States Environmental Protection Agency asked the Arizona Department of Health Services, Office of Environmental Health, to provide an evaluation of the health hazards that may result from exposure to soil and soil gas contaminants present on the West-Cap site, located just north of the Tucson International Airport. Improper waste disposal practices from previous industrial activities at the site have resulted in contamination of on-site soil and soil gas. The objective of this health assessment is to assess the potential adverse health impact to on-site workers from exposure to the on-site contaminated soil and soil gas. Community exposures are not presented in this public health assessment.
