This article analyses dealer satisfaction data in the agricultural technology market in Germany. The dealers could rate their suppliers in the ’overall satisfaction’ and in 38 questions which can be summarized in 8 dimensions. An ordinal regression model which is also known as the proportional odds model is used to analyse the ordinal scaled rating of the dealers. The ordinal regression model is a well examined method in econometric theory, but many authors prefer using a linear regression model due to better interpretation, even the assumptions of a linear regression do not fit the data. Since the estimated coefficients of an ordinal regression model can not be properly interpreted we show other methods for a better insight of the relationship of the... |

Information generated by precision farming technologies is of particular importance to producers. Precision farming technologies implies the ability to improve the management of production factors using site-specific information. This study examines factors influencing cotton farmers’ perceptions about the importance of crop consultants, farm input dealerships, Extension, other farmers, trade shows, the Internet and printed news/media for making precision farming decisions using a rank ordered logit model (ROLM). Results suggest that age, land tenure, income, percentage of income from farming, and location may affect farmers’ perceptions about the importance of different information sources when making decisions about precision farming technologies.... |

Building on the results of an initial analysis of risk ranking data collected from a representative group of some 850 Canadian respondents in early 2003, this study assesses a similar set of risk ranking questions applied to a somewhat larger representative group of some 1500 Canadians in late 2005. We also compare the 2003 and 2005 risk rankings. In both surveys, risk rankings for eight food safety issues (bacteria contamination, pesticide residuals, use of hormones in food production, use of antibiotics in food production, BSE (mad cow disease), food additives, use of genetic modification/engineering in food production, fat and cholesterol in food) and six environmental safety issues (water pollution by chemical run-offs from agriculture, soil... |

This paper reports on the findings of a study to investigate market outlet choice decision-making of urban consumers in Vietnam with regards to fresh pork purchases and generate empirical evidence on factors that influence these choices. Data from a survey of 600 consumers in Hanoi and Ho Chi Minh City was used to estimate a multinomial logit model of market outlet choice based on three alternatives: traditional temporary market outlets, permanent open markets, and modern retail outlets. Results suggest that market outlet choice by consumers of fresh pork in urban cities of Vietnam is conditioned by factors related to mobility and level of affluence, time budgets, concerns about food safety and hygiene, proximity to market outlets, and geographical... |

U.S. cheese consumption has grown considerably over the last three decades. Using a censored demand model and Nielsen Homescan retail data, this study identifies price and non-price factors affecting the demand for differentiated cheese products. Own-price and expenditure elasticities for all of the cheese products are statistically significant and elastic. Results also reveal that a strong substitution relationship exists among all cheese products. Although demographic influences are generally smaller than those related to prices and expenditures, empirical findings show that household size, college educated female heads of household who are age 40 and older, residing in the South, Central, and Western regions of the United States, as well as Black heads... |

The paper outlines a methodology that allows us to determine whether couples fertility is supply constrained based on the response they give to the subjective desired family size question. The central idea of the paper is that, when faced with the desired family size question, both constrained and unconstrained couples compare their demand for children with knowledge of their biological supply and unconstrained couples respond with a number while constrained couples respond with a qualitative response such as, It is Up to God (UTG), that essentially conveys the notion of demanding as many children as the supply function can yield. I then test this interpretation using data from Bangladesh. I find that controlling for demand side characteristics,... |

We used the 2009 Southern Cotton Precision Farming Survey data collected from farmers in twelve U.S. states (Alabama, Arkansas, Florida, Georgia, Louisiana, Missouri, Mississippi, North Carolina, South Carolina, Tennessee, Texas, and Virginia) to understand why farmers do not adopt seemingly profitable precision farming technology. Farmers provided cost, time constraint, satisfaction with the current practice and other as reasons for not adopting precision farming technology. Results from a multinomial logit regression model indicated that manure application on field, more formal education, larger farm size, participation in conservation easement or agricultural easement generally decreases the probability of nonadoption of precision agriculture in cotton... |
