Rising landfill costs have forced solid waste managers to consider waste stream reduction alternatives such as household recycling. Explaining the factors which motivate households to recycle is important to regions where households must bear a large portion of the recycling cost because unit-based garbage disposal fees and curbside recycling are not feasible options. Empirical results indicate that residents are responsive to constraints introduced by the household production technology, such as time costs and storage space, but are not responsive to variables measuring a recycling promotional program. Promotion efforts should switch focus from broader “public good” benefits of recycling to reducing household-level household production constraints.
Factors Affecting Adoption of Improved Maize Seeds and Use of Inorganic Fertilizer for Maize Production in the Intermediate and Lowland Zones of Tanzania [статья]
Опубликовано на портале: 24-11-2003Aloyce R.M. Kaliba, Hugo Verkuijl, Wilfred Mwangi Journal of Agricultural and Applied Economics. 2000. Vol. 32. No. 1. P. 35-47.
This paper examines factors influencing the adoption of improved maize seeds and the use of inorganic fertilizer for maize production by farmers in the intermediate and lowland zones of Tanzania. The results indicate that availability of extension services, on-farm field trials, variety characteristics and rainfall were the most important factors that influenced the extent of adopting improved maize seeds and the use of inorganic fertilizer for maize production. Farmers preferred those varieties which minimize field loss rather than maximizing yields. Future research and extension policies should emphasize farmer participation in the research process and on-farm field trials for varietal evaluation and demonstration purposes.

A tobit econometric procedure was used to examine the effect of selected demand and supply factors on nonreal estate agricultural lending by commercial banks in Texas. Results show that banks have reduced their agricultural loan portfolios in response to increased use of interest sensitive deposits after deregulation, Moreover, almost half of this decrease came from banks that stopped making agricultural loans. Also, results show that banks affiliated with multi-bank holding companies lend less money to agriculture relative to their assets than do independent banks.

Cattle producers and beef packers need to understandbasis determinantsas they develop price expectations and make pricing, hedging, and forward contracting decisions. This study empirically estimated factors explaining variability in monthly fed cattle basis. The five main results regarding live cattle basis are 1) corn price is an importantdeterminant, 2) a change in the value of the Choice-to-Select spreadpositively affects basis, 3) changes in the levels of captive supplies have no significant statisticalor economic impact on basis, 4) the June 1995 live cattle futures contract did not impact basis, and 5) both market fundamentalsand seasonal components are importantbasis determinants
Factors Affecting Production Efficiency in a New Alternative Enterprise: The Case of the Ratite Industry [статья]
Опубликовано на портале: 10-03-2005Jeffrey Gillespie, Alvin R. Schupp, Gary Taylor Journal of Agricultural and Applied Economics. 1997. Vol. 29. No. 2. P. 409-418.
Technical efficiency measures are calculated for ratite producers using data envelopment analysis. Regression analysis is then used to determine producer characteristics that are likely to lead to higher technical efficiencies. Results indicate that the most technically efficient ratite producers in Louisiana are not producing at the benchmark efficiency level advocated by the industry. Producer experience with other livestock, specialization, and labor are factors likely to lead to higher technical efficiency. These results are expected to hold for most new, alternative livestock enterprises.

Models are developed to measure the effect of socioeconomic factors on the probability of consuming fish and shellfish in both the away from home and at home markets. Factors that significantly affect the likelihood of eating fish and shellfish at home include: urbanization, region, race, ethnicity, age, diet status and income, On the other hand, region, employment, diet status, household size, age and income significantly affect the likelihood of eating fish and shellfish away from home.

Changes in consumer demand for poultry meats can be characterized as evolving over time and following seasonal patterns. The focus of this study is on understanding factors affecting wholesale poultry prices. This information is needed so that poultry processors and poultry producers may better understand how consumer purchasing patterns affect price changes. Results suggest that seasonal differences between the price of cuts exist. Furthermore, own-cut and cross-cut flexibilities were unique to individual cuts

A structural probit model is estimated to determine the change in the probability of selecting a milk handler. Cooperatives are thought to have lower prices and higher deductions than independent milk handlers and these Factors reduce the probability that a farmer will select a cooperative by 0.39 and 0.32. Cooperatives are thought to have better services and an assured market and payment than independent milk handlers and these factors increase the probability that a farmer will select a cooperative by 0.20 and 0.26. This indicates that many cooperative members value monetary characteristics over non-monetary characteristics.

Survey data of 2,538 dairy farmers located in 12 southern states were used to analyze the factors influencing farmers’ choice of milk handlers. Results from a qualitative response model indicate that a combination of price and non-price factors contribute to dairy farmers’ attitudes toward their milk handlers. Specifically, the decision to change milk handlers was significantly influenced by prices paid and deductions charged. However, non-price factors including field services, friendly personnel, and loyalty to a handler contributed to the longer term affiliation of dairy farmers with their milk handlers.

A multinominal logit model was estimated and used to analyze the impact of various producer characteristics on the adoption of flow-through and recirculating technology in soft-shelled crab production. Because of the industry’s geographic isolation and high turnover rate, data was collected by personal interviews in 1991. The results suggest that increased adoption might be fostered by targeting education programs towards full time, family operated businesses in nontraditional production regions. However, development of effective education programs may be hindered by the lack of a significant relationship between producer adoption decisions and the information provided by university or extension personnel.

This paper estimates on-farm impacts of adopting herbicide-tolerant soybean on herbicide use, yields, and farm profits, using an econometric model that corrects for self-selection and simultaneity and is consistent with profit maximization. The model is estimated using nationwide farm-level survey data for 1997. Given that the use of herbicide-tolerant soybeans involves the substitution of a particular herbicide-primarily glyphosate- for other herbicides, we explicitly consider this substitution process in the model.

Feedforward networks have powerful approximation capabilities without the “explosion of parameters” problem faced by Fourier and polynomial expansions. This paper first introduces feedforward networks and describes their approximation capabilities, then we address several practical issues faced by applications of feedforward networks. First, we demonstrate networks can provide a reasonable estimate of a Bermudagrass hay fertilizer response function with the relatively sparse data often available from experiments. Second, we demonstrate that the estimated network with a practical number of hidden units provides reasonable flexibility. Third, we show how one can constrain feedforward networks to satisfy a priori Information without losing their flexible functional form characteristic.

A sample of Kansas farms was used to examine the impact of risk and specialization on mean financial performance. Mean financial performance was hypothesized to be influenced by risk, age of the operator, percentage of acres owned, financial efficiency, leverage, specialization, and farm size. Risk, age of operator, financial efficiency, and farm size had the largest impacts on mean financial performance. Specializing in swine, dairy, or crop production increased mean financial performance, while specializing in beef production decreased mean financial performance. Farms with both crops and a livestock enterprise (beef, swine, or dairy) tended to have less variability in financial performance.
Fractional Cointegration and the False Rejection of the Law of One Price in International Commodity Markets [статья]

This study examines the Law of One Price (LOP) in international commodity markets using fractional cointegration analysis. For proper evaluation of the LOP, fractional cointegration analysis seems to be appropriate because of its flexibility in capturing a wider range of mean reversion behavior than standard cointegration analysis. Out of nine pairs of price series examined, fractional cointegration supports the existence of the LOP in eight cases, as compared to three cases using standard cointegration procedures. Overall, these results suggest that there is a long-run tendency for the LOP to hold for commodity prices.

An adaptive regression model is employed for estimating pre- and post-boll weevil eradication cotton-acreage response. Results indicate cotton acreage becoming more inelastic to own- and cross-price changes. As a result of this shift in acreage response and yield increases from eradication, net producer benefits on average are $88.73 per acre.
