Опубликовано на портале: 21-02-2005Patricia A. Duffy, Danny L. Cain, George J. Young Journal of Agricultural and Applied Economics. 2004. Vol. 25. No. 2. P. 119-133.
A five-year, 0-1, mixed integer programming model was developed to analyze the effects of 1990 Farm Bill legislation on the crop-mix decisions made on cotton farms. Results showed that, when compared to the 1985 Farm Bill, the 1990 Farm Bill can result in higher whole-farm income despite new “triple base” provisions limiting payment acres. The increase in income results from elimination of limited cross-compliance provisions and the change to a three-year base calculation. The model was also used to assess the likely impact of possible changes in the current legislation.

This study focuses on the development of a optimal harvest scheduling mathematical programming model which incorporates within-season changes in perennial crop yields. Daily crop yield prediction models are estimated econometrically for major commercially grown sugarcane cultivars. This information is incorporated into a farm-level harvest scheduling linear programming model. The harvest scheduling model solves for an optimal daily harvest schedule which maximizes whole farm net returns above harvesting costs. Model results are compared for a commercial sugarcane farm in Louisiana.

Environmental policies make a difference in shaping producers’ choices among dairy production technologies, the sizes and locations of their dairies, and even which dairies ultimately survive. Induced policy innovation means producers reacting to policies, and policies, in turn, being shaped by their effects. Profiles of experiences with environmental compliance in Texas and Florida were analyzed. Results demonstrate that the timing and sequencing of policy signals make a difference in compliance behavior and options. Furthermore, ex ante assessments of the costs of environmental compliance are challenging to carry out, and consequently can undermine the policy goal of maintaining the maximum number of options for compliance.

Alternative hypotheses of market integration in the US winter market for fresh tomatoes were evaluated using a dynamic model of spatial price adjustment. The results showed that while Florida and Mexico were integrated in the same market, a price change in one area was not instantaneously reflected in the other Lagged effects were important with long-run integration being supported for both Florida and Mexico and short-run integration for Mexico. However, the information flow, while relatively efficient, was not symmetric. Florida was found to be dominant in the price formation process with Mexico responding to changes in the Florida price.

Cotton and synthetic fiber competition in textile mills between 1961-1990was examined using a time-varying parameter regression model. Results indicate that the structure of demand for cotton is not stable and cotton’s share responses to changes in the prices of cotton and synthetic fiber vary over time. Cotton and synthetic fiber competition in textile mill use is essentially between cotton and noncellulosic fiber. Cellulosic fiber is not a cotton competitor.

International agricultural trade has evolved over time. Processed foods and developing countries have become major growth markets for U.S. agricultural exports, and foreign direct investment (FDI) has become even more important than exports as a means of accessing foreign markets. The critical question is whether FDI is a substitute for or a complement of exports. This research builds upon an existing theoretical FDI model and contributes to the literature through the development of a simultaneous equation system for FDI and exports, which is estimated using two-stage least squares. Empirical analyses examined the relationship between U.S. FDI and exports of processed foods into East Asian countries-China, Japan, Singapore, South Korea, and Taiwan-from 1989 to 1998. Results indicated a complementary relationship between FDI and exports. Additionally, these results indicated found that interest rates, exchange rates, gross domestic product (GDP), and compensation rates are important variables that influence U.S. FDI into East Asian countries, while GDP, exchange rates, and export prices are important export determinants.

The objective is to analyze the effects of country- and firm-specific factors on the return on equity in the beverage and tobacco and food and consumer-products industries for 11 industrialized nations. The results indicate that country- and firm-specific factors are important in explaining variation in return on equity within countries but not generally across countries or time.

This study investigates determinants of private capital formation in Greek agriculture and tests the “complementarity” against the “crowding out” hypothesis using multivariate cointegration techniques and ECVAR modeling in conjunction with variance decomposition and impulse response analysis. The results provide evidence of a significant positive causal effect of government spending on private capital formation, thus supporting the “complementarity” hypothesis for Greek agriculture.

Factors unique to the turkey industry suggest that conclusions concerning market structure and demand specification drawn from aggregate poultry data cannot necessarily be extrapolated to the turkey industry. The Wu-Hausman endogeneity test is used to examine demand specifications and industry structure specifically for turkey meat. In contrast to general poultry, quantity—not price—is found to be predetermined in demand models that use annual turkey data. Quarterly demand analysis suggests this result stems from biological cycles that limit a producer’s ability to react to price change and the use of a weighted average for determining price and quantity.

Human capital theory suggests that job opportunities will create incentives for human capital investment. If job information does not flow freely, or if they prefer not to move, students will make investment decisions based upon local job markets. Communities with a high percentage of low-skill jobs which do not reward high school and higher education do not create incentives for students to finish high school or continue beyond high school. Data from Virginia support this hypothesis. Targeted job creation, and improved labor market information may create incentives for increased human capital investment in many rural communities.
Lags in Real Property Revaluations and Estimates of Shortfalls in Property Tax Collections in North Carolina [статья]

Financing local public goods is a major issue in many communities, especially those that have experienced rapid growth. This paper analyzes problems associated with locally collected real property taxes where the real property tax base is only revaluated at long time intervals. Using counties in North Carolina as the subject of the analysis, we find that effective real property tax rates fall between revaluations. We calculate that a system of taxing market values of real property at a constant legislated tax rate would have yielded additional annual revenues of $320 million for North Carolina counties over 1980 to 1995.

Optimal crop and livestock mix was determined for a representative Alabama fhrrn using a dynamic programming model. Results indicate that decisions concerning livestock production are highly influenced by the amount of cotton base available on the farm. In most cases, increasing cotton base results in less cattle production. The triple base provisions of the 1990 Farm Bill, however, may give some cotton farmers an incentive to produce more stocker cattle during the winter months. Research results also indicate that the availability of farm programs can alter the optimal enterprise mix on a farm with no beginning base in cotton.

A capitalization approach is used to estimate econometrically the effects of exchange rate, interest rate and tax law changes on thoroughbred yearling prices. The analysis found that exchange rate and tax law changes have significantly influenced yearling prices since the early 1980s. Another serious price-reducing event was the 1986 tax law change. Both of these factors have counteracted the positive impact of increased purse rates on yearling prices.

Produced as a joint product, economic theory suggests that manure value could influence livestock management decisions such as herd size and optimal market weights. This study examines the concept of manure value and its connection with optimal replacement age or market weight, A model of a swine finishing operation representative of North Carolina conditions is developed. Over the range of conditions considered, manure value is negative and does not affect market weights. The marginal per head change in manure value is small relative to the marginal per head change in net returns from pork production. Further, economies of scale with respect to irrigation cause manure value to increase with herd size.

Efficient allocation of water requires knowledge of water’s value in both consumptive and nonconsumptive uses. This study estimates the marginal value of water in lake recreational and aesthetic (RA) use. An hedonic price equation (employing the Box-Cox functional form) indicates lake front location, distance to lake, and scenic view are significant RA characteristics of housing. Water front properties command a premium price for the private access they offer. Beyond the water front, the marginal RA price falls rapidly with increasing distance, becoming asymptotic to some minimum. Twenty-two percent of housing price is found to be attributable to the RA component.
