The organic CAS represents food quality without the use of synthetic chemicals to protect consumers＇ health. As a consequence, production costs and consumer prices have increased. The aim of this study is to analyze consumers＇ perception of the organic CAS label and how purchasing behavior for the product is influenced by converting the Fresh Milk Logo to the organic CAS certified label, which is based on contingent behavior analysis. This study adopts factor analysis to extract the perceptions and preferences of the respondents. In addition, the on-site Poisson model to revise the truncated and endogenous stratification and assess consumer welfare precision. The incremental consumer surplus for consumer consumed organic fresh milk is approximately NT$8,979.展开更多

Many researchers have focused on the economic costs of transportation system disruptions in transportation-related industries, specifically within commerce and logistics, in the assessment of the regional economic costs. However, the foundation of an assessment of the regional economic costs of a disaster needs to include the evaluation of consumer surplus in addition to the direct cost for reconstruction of the regional transportation system. The objective of this study is to propose a method to estimate the regional consumer surplus based on indirect economic costs of a disaster on intermodal transportation systems in the context of diverting vehicles and trains. The computational methods used to assess the regional indirect economic costs sustained by the highway and railroad system can utilize readily available state departments of transportation （DOTs） and metropolitan planning organizations （MPOs） traffic models allowing prioritization of regional recovery plans after a disaster and strengthening of infrastructure before a disaster. Hurricane Katrina is one of the most devastating hurricanes in the history of the United States. Due to the significance of Hurricane Katrina, a case study is presented to evaluate consumer surplus in the Gulf Coast Region of Mississippi. Results from the case study indicate the costs of rerouting and congestion delays in the regional highway system and the rent costs of fight-of-way in the regional railroad system are major factors of the indirect costs in the consumer surplus.展开更多
