In this paper we seek to characterize the robustness of the ENSO/soybean price relationship and to determine whether it has practical economic content. If such a meaningful relationship exists, the implications could be profound for commodity traders and for public sector investments in climate forecasting capabilities. Also, the validity of economic evaluations of climate impacts and climate forecasts based on ENSO-price independence would come into question. Our findings suggest a relationship between interannual climate and soybean prices, although we are not able to attribute the relationship to ENSO or to say that ENSO is economically important.

Mathematical programming results revealed that moving toward more flexible agricultural policies would generate substantial economic and environmental gains in a North Carolina diversified cropping region, But in a Washington-Idaho dry land grains region, only the use of relatively new and sometimes problematic alternative cropping systems permitted environmental and economic gains under policy reform. In both regions, a recoupling policy, which links government payments to resource-conserving farming practices, was needed to protect environmental quality when market prices for program crops were high.

A net trade model that includes environmental variables is used to analyze economic and environmental implications of various EC policies, There are environmental benefits from CAP reform, but a fertilizer tax results in greater nitrate and phosphate abatement. The input tax also results in smaller drops in EC farm income compared to CAP reform.

As the environmental policy recommendations of economists become more acceptable, differences in the professional understanding of, and support for, different policy forms are becoming more apparent. These different approaches to environmental policy and research are described around a taxonomy of four perspectives: “rational analysts;’ “cost analysts;’ “market managers;’ and “free market environmentalists.” These perspectives are compared and contrasted. Recognition of these differences can result in a better appreciation of the different research agendas of economists and can improve clarity in teaching and policy advising.
Environmental Regulatory Reform and the Unholy Trinity: Unfunded Mandates, Risk Assessment, and Property Rights [статья]

Major regulatory reform issues which involve environmental policy include issues of unfunded mandates, risk assessment, and property rights, Each of these proposed reforms involves major changes in environmental policies with impacts on different groups. Property rights is the core issue in Congress and state legislatures, with both regulatory takings and just compensation being the major parameters. Economists can participate effectively in this policy debate with successful research and education programs addressing the divisive issues.
Estimating Insecticide Application Frequencies: A Comparison of Geometric and Other Count Data Models [статья]

The number of insecticide applications made by an apple grower to control an insect infestation is modeled as a geometric random variable. Insecticide efficacy, rate per application, month of treatment, and method of application all have significant impacts on the expected number of applications, The number of applications to control a given insect population is dependent on the probability of achieving successful control with a given application. Results suggest that northeastern growers have the highest and mid-Atlantic growers the lowest probability of controlling an infestation with a given application. Results also indicate that scales require the least and moths the most number of applications. Growers are not responsive to per unit insecticide prices, but respond negatively to insecticide toxicity, supporting findings from previous pesticide demand analyses.

Using a stochastic version of the POLYSYS modeling framework, an examination of projected variability in agricultural prices, supply, demand, stocks, and incomes is conducted for corn, wheat, soybeans, and cotton during the 1998–2006 period. Increased planting flexibility introduced in the 1996 farm bill results in projections of significantly higher planted acreage variability compared to recent historical levels. Variability of ending stocks and stock-to-use ratios is projected to be higher for com and soybeans and lower for wheat and cotton compared to the 1986-96 period. Significantly higher variability is projected for corn prices, with wheat and soybean prices also being more variable. No significant change in cotton price variability is projected.

Stochastic index theory views each commodity price change as an independent observation on the rate of inflation that can be estimated by averaging over all prices. Our methodology estimates both the overall rate of inflation and relative price changes along with standard errors.

Nature-based tourism (NBT), alternatively known as ecotourism, is a rapidly expanding area in the tourism travel sector. States such as Louisiana with a well established urban-based tourism industry may have expansion opportunities through development of complementary nature-based tourism. This study analyzes the decision to participate in nature-based tourism and identifies factors, including attitudinal, that influence the decision to participate in NBT among Louisiana tourists.

Agricultural exports are important to many regional economies, as is the case for agricultural exports either produced in or shipped through Louisiana. A hybrid (revised and verified) IMPLAN model of the Louisiana economy is used to estimate the direct and indirect impact of agricultural exports. Original model estimates of foreign exports lacked holistic (overall) accuracy. However, other, more general uses of the model were unaffected by this lack of accuracy. While the contributions of agricultural exports to the state economy were substantial, impacts were concentrated in unprocessed products. Increasing the export of processed agricultural products should enhance economic activity.
Evaluating the Performance of Agricultural Bank Management: The Impact of State Regulatory Policies [статья]

We evaluate agricultural bank management performance, focusing on the impacts of interstate banking laws on productivity change. The generalized Malmquist productivity index decomposes productivity change into technological change, technical efficiency change, and change in scale economies. While managerial productivity rose from 1982 to 1991, states that adopted the most liberal interstate banking laws experienced the greatest improvement in productivity. Large agricultural banks were more efficient in states that had more liberalized interstate banking laws while small agricultural banks fared better in states with more restrictive laws.
Evaluating the Short- and Long-run Economic Impacts of the Virginia-Maryland Regional College of Veterinary Medicine [статья]

Colleges of veterinary medicine are often asked to provide evidence of the economic impacts of their activities. This paper presents methods for evaluating a veterinary college and applies them to the Virginia-Maryland Regional College of Veterinary Medicine. It assesses short-run impacts on income and employment using input-output analysis. Long-run benefits are estimated using a combination of economic surplus analysis, travel cost analysis and demand estimation, animal-owner willingness-to-pay based on a survey of practicing veterinarians, and earnings differentials.

Impacts of alternative specifications for heteroscedastic error structures are examined by estimating various production functions for corn in Central Texas. Production- and profit maximizing levels of inputs and the shape of the profit equation obtained from models not corrected for heteroscedasticity differed from those obtained from models corrected for heteroscedasticity. Using the profit-maximizing input levels for each production function gave essentially the same estimated yield and profit, regardless of the specification for heteroscedasticity employed. Differences of up to one-quarter to one-third are noted, however, in the amount of profit maximizing levels of inputs used, depending on the heteroscedasticity correction.

With sustained appreciation of the U.S. dollar over the past 4 years, the exchange rate has again taken on importance for agriculture. This overview paper revisits analysis of exchange rate impacts, reviewing the relevant conceptual arguments, summarizing the evidence economists and agricultural economists have marshaled from the 1970s and 1980s and from several more recent papers, presenting some illustrative recent empirical analysis of exchange rate effects, and briefly examining the detrimental consequences that sustained appreciation of the dollar is having on U.S. farm policy.
Experimental Examination of a Thin Market: Price Behavior in a Declining Terminal Market Revisited [статья]

Perceived characteristics of thin markets are described and approaches to furthering their study are suggested. Design features of a laboratory thin market, patterned after a typical livestock marketing situation, are described. Price bias and variation from a “thick” private negotiation market with 22 traders is compared to that from a “thin” auction market with 8 traders. No systematic price bias was found m any of the markets. Price variation was actually lower in the thin auction market.
