This article examines farmers' preferences for both cropping and management practices, which are of policy interest because of their environmental impact. We present the results of a choice experiment survey of all agricultural decision makers in the Camargue region. A latent class model identified three classes. The main class encompasses farmers complying with the norms of the Protected Geographical Indication (PGI): Riz de Camargue. We estimated the monetary value of each of the relevant agricultural practices. Our results make a strong case for differentiating incentives to encourage environmentally friendly practices and identify the diversity of values attached to the main components of rice cropping technology in the area. Estimates of the implicit prices indicate that most rice growers can be persuaded to adopt environmentally friendly practices. These findings could help in designing targeted contracts according to farmers' preferences, in line with conservation or environmental objectives. © 2013 The Agricultural Economics Society. Source

We consider a periodic review perishable inventory system. Item lifetimes are random and assumed to follow an Erlang distribution. This is a rich modeling allowing us to cover various cases of lifetime variability in practice. The demand process is assumed to be Poisson and the order lead time is constant. For the extreme cases of exponential and deterministic lifetimes, we provide an analytical approach for the system performance evaluation. We also conduct a simulation study to examine the important effect of lifetime variability mixed with the cost parameters on the total operating cost. It appeared that there might be opportunities to considerably improve the operating cost in the case of high lifetime variability. This is more apparent for cases with large outdate, lost sale, and purchasing cost parameters. © 2015 Elsevier B.V. All rights reserved. Source

Designers and marketing managers often agree that visual codes, in terms of product and package design, typify certain product categories. These "category-based visual codes" refer to the formal and graphic characteristics most frequently seen in a given category, like specific shapes, colors, materials, typefaces, layouts, and illustrations. Given that the concept of "category-based visual codes" seems to be connected with the concepts of "perceived typicality," "cognitive categories," "family resemblance," and "design newness," this research examines the impact of typicality/atypicality judgments regarding the visual appearance of a product on consumers' aesthetic appreciation and purchase intent. Several studies have sought to determine the relationships among design perceived typicality, aesthetic appreciation, and purchase intent. However, the literature indicates contradictory results. While some studies have shown a preference for the most typical design, others have demonstrated that consumers prefer moderately atypical design. This paper offers an explanation for this discrepancy by providing evidence that the relationships among design perceived typicality, aesthetic appreciation, and purchase intent are a case of moderated mediation. An empirical study using wine labels was conducted with 780 respondents. The results indicate that the relationships among perceived typicality, aesthetic appreciation, and purchase intent are linear and positive, although several individual variables have a moderating effect. Thus, it appears that certain consumer segments are more likely to appreciate atypical packages. Moreover, the level of perceived risk at the time of purchase also plays an essential role. Consumers are more apt to accept atypical packaging when the perceived risk is low. Several theoretical and managerial implications are drawn from these results. © 2014 Product Development & Management Association. Source

While many crop insurance systems have been reformed around the world, few academic researches have addressed the determinants of the decision on crop insurance at the farm's micro level. In this article, both the financial and the agricultural literature lead to the identification of many rationales for the crop insurance decision. Using data from the period 2003-2006 on a representative survey of French farms (FADN-RICA), we investigate the different factors that incite farmers to insure against crop risk. We emphasize that the highest risk farms are more likely to have insurance and this decision is positively related to the past amount of claims. Insurance is subscribed by larger farms because insurance appears too expensive for smaller farms, which are indeed naturally less diversified. Interestingly, financial variables (such as capital structure or return on investment) do not significantly determine the insurance decision. © 2011 International Association of Agricultural Economists.

This article investigates the relationships between various types of educational value generated by the Markstrat simulation game. Considering several theoretical models of experiential learning and the research framework proposed by previous studies, an educational value generation model is developed and validated, using primary data collected from 305 UK-based students. Four types of educational value are identified: experience generation, conceptual understanding, skills development, and affective evaluation. The application of structural equation modelling indicates several significant relationships: experience generation has a strong impact on conceptual understanding, and both of them have medium to high direct impacts on skills development. On the other hand, the participants' perception regarding the professional skills developed during the simulation game determines their affective evaluation of the Markstrat exercise. The model presented in this study is generalizable to other simulation games, and to other academic disciplines that implement the same experiential learning approach. © 2014 Elsevier Inc.
