This article provides an empirical study on the relationship between auction characteristics and prices using a data set on cherry sales from the online auction site Yahoo! Kimo. Using three alternative measures of the dependent variable, results indicate that reputation variables have a statistically important association with auction prices. The extent of reputation's impact on prices varies substantially depending on the model specification and estimation technique. The article highlights the effectiveness of a nonlinear specification for both measuring and interpreting the underlying reputation variables. The use of a “Buy It Now” option, size, and country of the origin is correlated with prices at statistically significant levels. Several econometric concerns regarding the empirical modeling strategy are discussed.  相似文献

Ecolabelling is an increasingly important tool used in the promotion of sustainable forestry and fishery products around the world. Whether the consumer is actually paying a price premium for ecolabelled products is of fundamental importance as it indicates a return on the investment of sustainable practices, providing an incentive for producers to undertake such practices. This article seeks to address the question of whether or not an actual premium is being paid by consumers for ecolabelled seafood by conducting a hedonic analysis of Marine Stewardship Council (MSC)‐certified frozen processed Alaska pollock products in the London metropolitan area in the UK market using scanner data. Regression results show a statistically significant premium of 14.2%. This implies the presence of market differentiation for sustainable seafood and the potential of the MSC’s fisheries certification programme to generate market incentives for sustainable fisheries practices.  相似文献

Previous analyses of dairy farm structural change focus on the variation over time in one or a small number of regions. We present an EU‐15 cross‐regional analysis of the development of dairy farm numbers in different size classes over the period 1995–2005. Our purpose is to measure the explanatory relevance and effect of key factors suggested in the theoretical and empirical literature on structural change. Apart from the unprecedented scope, the underlying Markov chain analysis also contributes by combining observed transitions in micro (farm level) data with macro (sector level) data on farm numbers. Results show widely significant impacts of most considered explanatory variables, but also reflect and illuminate the complexity of the underlying processes.  相似文献

We analyse the impacts of direct income transfers on the technical efficiency of Greek olive farms. We use a production frontier function and a non‐monotonic inefficiency effects model, which incorporates the influences of exogenous variables (subsidies, farm characteristics, etc.) on technical efficiency. The model is applied to 1995–2004 FADN data. The results show that direct transfers of the CAP had a negative and monotonic effect on technical efficiency, whereas the degree of specialisation had a non‐monotonic effect on technical efficiency.  相似文献

The objective of this paper is to develop a multiperiod, finite‐life, life cycle models of household decisions on food, leisure, and health (body mass index [BMI] or being obese) and to estimate econometric versions of these models treating SNAP (Supplemental Nutrition Assistance Program) participation as endogenous. A key insight from the economic models is that households allocate their wealth over the multiperiod life cycle to equalize the marginal utility of wealth in each period. The observations for this study are a balanced panel of over 1,600 women from the National Longitudinal Survey of Youth, 1979 Cohort (NLSY79). We focus on the 20‐year period starting in 1986, when SNAP data first became available. Women of all ages are included in the study because at the beginning of adulthood women cannot accurately predict over their life cycle labor and marriage market and health shocks that can thrust them into an economic position where they would qualify for SNAP. New findings include that a woman's household SNAP participation with or without updating for last periods health status and higher local dairy product prices reduce significantly her BMI and probability of being obese.  相似文献

This study estimates price determinants for specialty green coffee auctions using records from the 2004–2010 Cup of Excellence programs hosted by the Alliance for Coffee Excellence. While some literature on coffee has focused on certifications and sustainability labels, the discussion of price determinants has been limited. This article replicates one of the first publications on price determinants and formulates a new model to more accurately describe the market. We include the necessary additional variables and estimate the model using a truncated maximum likelihood estimation technique. While sensory quality has a strong effect on price, the highest premiums stem from obtaining a top rank compared to other coffees from the same country, and North American buyers are more responsive to sensory quality than buyers in Asian and European markets.  相似文献

Using a nationally representative sample of farm households from India, this paper examines the impact of use of information on net farm incomes. Employing methodologies that mitigate potential biases in the estimation of the impact, the empirical results show that farmers who use information realize over 12% higher net returns per hectare. The paper also establishes a pecking order in access to information. Small farmers and those at the bottom of social hierarchy (based on caste) have access to fewer information sources, and they depend more on informal social networks and input dealers for their information needs. The larger farmers and those from upper caste rely relatively more on sources such as radio, television and newspaper.  相似文献

This study analyses the effect of the spatial factor, location, and interaction effects among peer companies, on the productivity growth of agri‐food companies in Spain. With this aim, we build a productivity growth index and apply a multiequational Seemingly Unrelated Regression on a sample of 344 Spanish cooperatives and investor‐owned firms for the period 2010–2012. Our findings show that agri‐food firms are influenced by spatial factors finding interesting differences between cooperatives and investor‐owned firms. With regard to the geographical location, cooperatives in the western of Spain show higher productivity growth rates, whereas investor‐owned firms in the northeast of Spain present better results. The interaction effect among closer peer companies is also a relevant factor to determine the productivity growth in agri‐food companies. This factor is more relevant for cooperatives than for investor‐owned firms.  相似文献

What is the impact of product certification on small‐scale farmers’ livelihoods? To what extent does the participation of Ethiopian small‐scale coffee farmers in certified local cooperative structures improve their socioeconomic situation? To answer these questions, this article employs household data of 249 coffee farmers from six different cooperatives collected in the Jimma zone of Southwestern Ethiopia in 2009. Findings show that the certification of coffee cooperatives has in total a low impact on small‐scale coffee producers’ livelihoods mainly due to (1) low productivity, (2) insignificant price premium, and (3) poor access to credit and information from the cooperative. Differences in production and organizational capacities between the local cooperatives are mirrored in the extent of the certification benefits for the smallholders. “Good” cooperatives have reaped the benefits of certification, whereas “bad” ones did not fare well. In this regard the “cooperative effect” overlies the “certification effect.”  相似文献

This study examines the effects of off‐farm income on food expenditures of rural Bangladeshi households. Our analysis yields unbiased estimates of the unconditional impact of off‐farm income on food expenditures and reveals the heterogeneous effects that occur across the distribution of total food consumption expenditures. The findings suggest that the impacts of off‐farm income are uniformly positive across the unconditional quantile regression and significantly increase food consumption expenditures for all quantiles, except for the 25th quantile. In addition, we found that schooling, experience, and location of the household increase the food expenditures of rural households. Most importantly, this article argues that female‐headed rural households in which the female works off the farm tend to have significantly lower food expenditures.  相似文献

In 2013, Ethiopia's Agricultural Transformation Agency introduced the Wheat Initiative to increase smallholder productivity. In this article, we measure the impacts of the Wheat Initiative package of technologies, and its marketing assistance component alone, on yields among a promotional group of farmers. The package includes improved techniques, improved inputs, and a guaranteed market for the crop. Relying on crop‐cut measures and farmers’ own assessments, we find that full package led to an average 14% higher yields. Implementation of the Wheat Initiative was successful in making certified seed and fertilizer accessible to farmers and increasing their uptake, though only 61% of the intervention group adopted row planting and few farmers received marketing assistance. The measured yield difference may underestimate the true yield difference associated with the technology because of incomplete adoption of the recommended practices by intervention farmers and adoption of some practices by control farmers.  相似文献
