Modeling non-compensatory preferences in environmental valuation

Submitted by Luat Do on

While the compensatory model of choice dominates the environmental valuation literature, non-compensatory models, where individuals do not tradeoff one attribute for another, are sometimes found to be better representations of choice behavior. Most non-compensatory models employ “cutoffs”, the point at which utility abruptly changes. But cutoffs are usually elicited directly from respondents using a stated preference question. Such elicitation could be inaccurate and might introduce bias to the decision process. In this article, we develop a model that estimates cutoff levels endogenously.

Vulnerability to climate change and the variations in factors affecting farmers’ adaptation: A multi-group structural equation modelling study

Submitted by Luat Do on
EfD Authors:

This study investigates how factors that influence farmers’ intentions to adapt to climate change differ from each other in regions with different levels of vulnerability to climate change. Data were collected from interviews with 598 rice farmers in Dong Thap, Soc Trang and Long An provinces in the Mekong Delta, Vietnam. These provinces were identified respectively as highly, moderately and mildly vulnerable to climate change. Multi-group structural equation modelling was employed.

Modelling the Effect of Chronic Wasting Disease on Recreational Hunting Site Choice Preferences and Choice Set Formation over Time

Submitted by Luat Do on

Chronic wasting disease (CWD) is a prion disease that affects deer, elk and other cervid wildlife species. Although there is no known link between the consumption of CWD affected meat and human health, hunters are advised to have animals from CWD affected areas tested and are advised against consuming meat from CWD infected animals (Government of Alberta 2010). We model hunter response to the knowledge that deer in a wildlife management unit have been found to have CWD in Alberta, Canada.

The estimate of world demand for Pangasius catfish (Pangasiusianodon hypopthalmus)

Submitted by Luat Do on
EfD Authors:

This research described in this article aimed to investigate international market potentials for Pangasius catfish (Pangasianodon hypopthalmus). The monthly export data from Vietnam, which accounts for more than 95% of the global export value, in the period 2007 to 2014, were used to estimate a non-linear Inverse Almost Ideal Demand System of the seven market regions.

Using labeled choice experiments to analyze demand structure and market position among seafood products

Submitted by Luat Do on
EfD Authors:

Understanding market competition and consumer preferences are important first steps in developing a business. In a competitive market, the effectiveness of the various elements of a firm's marketing mix depends not only on the absolute value of each element but also on the relative values of the elements with respect to the firm's position in the market. In this paper, we analyze the demand structure and market positions of a variety of seafood products in the French retail market. We used a labeled choice experiment to analyze 12 seafood species.

Modeling farmers’ decisions on tea varieties in Vietnam: a multinomial logit analysis

Submitted by Luat Do on
EfD Authors:

This article analyzes households’ choice on tea varieties in Vietnam by using a multinomial logit model. The modeling takes into account the issue of unobserved individual heterogeneity and the endogeneity of some explanatory variables (use of chemical and organic fertilizers). The results show that important factors influencing the decision to adopt one type of tea varieties include income, age, household size, farming contract, and use of organic fertilizers, but also membership of professional associations such as the Tea Association and the Farmers Union.

The determinants of self-medication: Evidence from urban Vietnam

Submitted by Luat Do on

This study examines the primary determinants of self-medications among urban citizens in Ho Chi Minh City, Vietnam using survey data. Employing logistic models, the article finds that the probability of self-medication is positively associated with the respondents' high school degree or vocational certificate, married status, and income while it is negatively related to employed status, the number of children, the geographical distance from home to the nearest hospital, doing exercise, and living in a central region.

South-East Asian ricardian studies: Bangladesh, Sri Lanka, Thailand, and Vietnam

Submitted by Luat Do on
EfD Authors:

Bangladesh, Sri Lanka, Thailand, and Vietnam each conducted a Ricardian analysis of crop net revenue (NR) in their country. The countries defined seasons slightly differently depending on their monsoon and dry periods. They also sometimes included slightly different variables in their regressions. The countries are small so that the climate results are often insignificant. However, the Ricardian model does predict near term damage in Bangladesh in the CanESM climate scenario and near and far term damage in Thailand in the CMCC climate scenario.
