In recent years the organic food industry has been expanding and sales of organic products have been increasing. Abundant studies have been done focusing on organic fruits and vegetables which focused on the shortage of organic live stocks. In this paper we focus our attention on organic pork products. Using a sample of 400 Thais consumers, this study proposes the contingent valuation （CV） technique to measure the willingness of individuals to pay a price premium for organic pork in Thailand. In order to obtain the mean ＂willingness to pay＂ （WTP）, a bivariate probit model was applied to provide information about the crucial variables that affect the WTP. The study revealed that variables that better approximate WTP are based on the lifestyle and knowledge about organic foods rather than the usual socioeconomic factors. The mean WTP on the premium price for organic pork is approximately 34.30 Bath per kg. In order to access the market potential this study shows that the suitable attributes of organic pork which is consistent with consumer preferences are composed of modernized and environmental packaging with special product details. Marketing this product to the buyer it should be set at a reasonable price. Stimulating the market should be done by doing sales promotion and public relations on a regularly basis. In addition, organic pork should be available in any places and convenient for customers to buy.展开更多

Due to travel restrictions by governments and increased perceived risks of the disease, therehave been significant changes in social activities and travel patterns. This paper investigates the effects of COVID-19 on changes toindividuals’ travel patterns, particularly for travel purposes. An online questionnaire survey was conducted in China, which incorporatesquestions about individuals’ sociodemographic and travel characteristics in three different periods of COVID-19 (i.e. before theoutbreak, at the peak and after the peak;the peak here refers to the peak of the pandemic in China, between the end of January and1 May, 2020). The results show that trip frequency decreased sharply from the outbreak until the peak, and drastically increased afterthe peak. Nevertheless, the data fromthis study suggests that it has not fully recovered to the level before the outbreak. Subsequently,a series of random parameters bivariate Probit models for changes in travel patterns were estimated with personal characteristics.The findings demonstrate that during the peak of the pandemic, residents who did not live in more developed cities reached lowfrequencytravel patterns more quickly. For travel purposes, residents of Wuhan, China resumed travelling for work, entertainmentand buy necessities at a much higher rate than other cities. After the peak, students’ travel for work, entertainment and to buy necessitiesrecovered significantly faster than for other occupations. The findings would be helpful for establishing effective policies tocontrol individual travel and minimize disease spread in a possible future pandemic.展开更多
