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.

Which farming systems are efficient for Vietnamese coffee farmers?

Submitted by Luat Do on
EfD Authors:

This paper provides a comparative assessment of the productive efficiency of three common coffee growing systems in Vietnam: mono-cropping, synchronization and segregation. Results from an input distance function approach deliver several important findings. First, the average inefficiency level is estimated to be around 18% although inefficiency varies significantly between the three farming systems.

Mangrove forests and aquaculture in the Mekong river delta

Submitted by Luat Do on

The mangrove area in Viet Nam is dramatically decreasing in the last decades. Since 1995, mangrove forests in south Viet Nam are allotted and contracted to households for protection, management and logging. Under this policy, households are allowed to convert 20–40% of the allotted forests into other uses, mainly shrimp farming. Most households develop mixed shrimp-mangrove farming systems, in which shrimp ponds are mixed with mangrove forest.

Do the more educated utilize more health care services? Evidence from Vietnam using a regression discontinuity design

Submitted by Luat Do on
EfD Authors:

In 1991, Vietnam implemented a compulsory primary schooling reform that provides this study a natural experiment to estimate the causal effect of education on health care utilization with a regression discontinuity design. This paper finds that education causes statistically significant impacts on health care utilization, although the signs of the impacts change with specific types of health care services examined.

The role of packaging format, alcohol level and brand in consumer’s choice of beer: A best-worst scaling multi-profile approach

Submitted by Luat Do on
EfD Authors:

Although beer is widely consumed around the world and has the largest market share among alcoholic beverages, there is a paucity of studies on consumers’ preferences for beer compared to wine. In this study, consumers were asked to select the best and worst favorable beer from choice sets of a labeled choice experiment, in which choice options were labeled by brand names.
