In Southeast Asian countries (SEA), road transport accounts for the main energy consumption and CO2 emission. Air pollution is a major concern in densely populated cities such as Bangkok, Manila, and Kuala Lumpur. The main objective of this paper is to give insights on trends of transport development, car ownership, and CO2 emissions in Southeast Asia. This study also attempts to review the successful transportation policies around the globe and to introduce the possible instruments that can help reduce air pollution (...) in Southeast Asian countries. Economic instruments to estimate the benefits of a cleaner environment due to new policies are introduced as well. The results of this research could help policy makers consider approaches that could internalize external costs of transportation and maximize the societal welfare. (shrink)

Choice experiment (CE) is a questionnaire based method that the accuracy of research questionnaire determines the validity of the research outcomes. Attribute selection has a prime importance in every CE studies. If respondents do not understand or do not have preference for a certain attribute, the attribute non-attendance problem might happen that biases overall results of the research. Qualitative approaches such as literature review, focus group discussion, and in depth discussion commonly applied in CE researches. However, especially in the developing (...) countries context where ethnical and cultural diversity is a challenge in conducting survey based questionnaires, qualitative methods are not sufficient in selecting attributes. Present study investigates the application of relative importance index (RII) in respondents¡¯ preference for attributes in a modal shift study in Klang Valley, Malaysia. The 5 point Likert scale questions were employed to enhance respondents¡¯ preferences for initial 24 selected attributes. The results of this study showed that from 24 pre-selected attributes, only 18 of them had RII>0.5 and could be included in the final CE design. The results of this study could help researchers to control for unobserved problems in selecting the attributes which could not be discovered through qualitative approaches. -/- . (shrink)

Good agricultural practices certification schemes have been promoted to enhance agricultural sustainability. This study seeks to explain the adoption of GAP certification schemes through an analysis of the role of personal values in guiding such choice. It is a departure from approaches taken in previous studies in the area. Through the laddering interview technique of means-end chain analysis, a hierarchical value map was systematically schematized to illustrate the relationship between adoption of GAP, outcomes, and personal values driving the choice. The (...) personal values identified in this study cluster under the headings of “better life”, “religious responsibility”, “healthy life”, and “responsible farmer”. Amongst these, the main evidence pointed to the desire to have “better life” through the enhanced financial position that is perceived to arise as a consequence of GAP adoption as being of primary importance. These findings suggest that, while profit is not the sole end driver of adoptive behavior, GAP certification schemes have to be seen as lucrative and to enhance the goals of achieving core personal values. Other empirical information in this study also has significant policy implications. It is a key finding of this paper that effective promotions of GAP should be tailored and targeted at specific segments of the farmer population. (shrink)
