| This study determined the factors (related to fixed and variable transaction costs) influencing the decision to participate in sweet potato markets by a random sample of 320 small holder farmers in south eastern Nigeria. Data were collected with structured and validated questionnaire, and analyzed using the ordered probit analysis procedure. Participation decisions revealed that marketing experience, farm size, membership of cooperatives/social organizations, extension contact, farming experience and road conditions to the nearest town had positive relationship with decision to be autarkic other than buyer and to be seller other than autarkic, and were significant at 1% level of probability. The coefficient of age, household size, and output were also... |

| Of twenty-three agricultural economics conjoint analyses conducted between 1990 and 2001, seventeen used interval-rating scales, with estimation procedures varying widely. This study tests cardinality assumptions in conjoint analysis when interval-rating scales are used, and tests whether the ordered probit or two-limit tobit model is the most valid. Results indicate that cardinality assumptions are invalid, but estimates of the underlying utility scale for the two models do not differ. Thus, while the ordered probit model is theoretically more appealing, the two-limit tobit model may be more useful in practice, especially in cases with limited degrees of freedom, such as with individual-level conjoint models. |

| Results from continuous tracking of consumer confidence and media coverage of food safety events over a 67 week period between May 2008 and August 2009 are reported. An ordered probit model is used to test the hypothesis that media coverage of food safety events affects consumer confidence in the safety of the U.S. food system. The results show that media coverage significantly and negatively affected consumer confidence in the safety of nation’s food supply during the sample period. Socioeconomic and demographic factors such as geographic region, use of media source, household size, age, ethnicity, education, and gender also had significant affects on consumer confidence in the safety of United States food supply. |

| This paper analyses the extent and determinants of rural household poverty in the eastern highlands of Ethiopia. We study 216 households using a household consumption expenditure approach. We are particularly interested in the effects of location-specific and institutional factors (networks) in determining the probability of being poor. Our findings suggest that poverty is location-specific, depends on access to irrigated land (not land per se) and access to non-farm income. Results also indicate that household wellbeing is negatively affected by household size, and positively affected by age of household head. Involvement in governance, social and production related networks is also found to be strongly associated with the probability of a household be... |

| An information asymmetry exists in the market for organic produce since consumers cannot determine whether produce is organically or conventionally grown. Various methods may solve this problem including signaling, reputation, and certification. Signaling and reputation may not work well, because signals are noisy, and reputation may be difficult for a producer to establish. Certification of the farm and its growing methods shows the most promise. A survey instrument testing the efficacy of certification is presented along with empirical analysis suggesting that no notable difference existed between independent certification methods, although independent certification had significantly different effects than self-certification. |

| Slowing productivity growth in the Australian grains industry has led to calls for increasing investment in rural R&D to advance agricultural technology. However, recent research also suggests there is strong potential to increase productivity by enhancing uptake of existing innovations. The productivity gains from innovation adoption are likely to depend on the capacity of farmers to effectively select, adapt and integrate innovations into existing farming systems. In this paper, the innovative capacity of grain growers is characterised by variables related to the farm, the farmer and their operating environment. The influence of these factors on on-‐farm innovation adoption is tested using an ordered probit model. The relationship between innovative... |

| Student evaluation of teaching (SET) is employed as an aid in improving instruction and determining faculty teaching effectiveness. However, economic theory indicates the existence of externalities in SET scores that directly influence their interpretation. As a test of this existence, a multinomial-choice, ordered data estimation procedure is employed to identify course externalities influencing SET. These externalities include student class standing, required courses, class size, days a class meets, class meeting time, classroom location, and classroom design. Results indicate that externalities have a significant impact on teaching evaluations. Thus, failure to internalize these externalities will lead to biases in SET and questionable use of SET... |

| Abstract: This paper examines the factors that influence earned income of organic farmers given their decisions to engage in local selling. The model explicitly accounts for the sorting of producers across different levels of commitment to local sales on the basis of both observable and unobservable heterogeneity. The significant selectivity coefficients confirm that when producers choose to market organic products primarily through local outlets, earnings are overestimated (biased upward) if the selectivity corrections are neglected. Positive selection effects are present for farmers most intensively involved in local sales, contributing to higher earnings on average for these producers. |

| This paper analysed the factors influencing the acceptance of functional foods (FFs) of three distinct groups of young Italian consumers. We implemented an ordered probit model based on data collected in a field survey carried out in southern Italy in 2008. The results showed that different sources of information and knowledge (e.g. the internet, newspapers and universities), judgements and motivations (e.g. taste and health effects credibility) are key elements in the acceptance of FFs. This implies the need to identify highly differentiated communication and marketing strategies for both public agencies and private firms in order to promote FF consumption. |
