Thailand's real gross domestic product growth has fallen to a permanently lower trend, making it the worst performer in the Southeastern Asian region. The export sector, the country's long‐standing growth engine, has sputtered due to the declining competitiveness of the manufacturing sector. Chronic political instability during the last two decades has resulted in the adoption of short‐sighted policies, in particular, populist policies designed specifically to garner votes rather than improve the long‐term productivity of the business sector. The military coup was expected to restore political stability and end costly populist policies introduced by elected civil governments. Unfortunately, as the military government develops its long‐term political aspirations, it, too, seeks the assistance of populist policies to ensure its political success. Thailand has promulgated laws and regulations to ensure fiscal discipline, but it has yet to be seen whether the letter of the law can help prevent such populist policies in practice.  相似文献

研究了影响黄酒非生物稳定性的主要因素:酒样中添加牛血清白蛋白(BSA,分子量68KD),酒体浊度可达到最大值,继续添加蛋白质,酒体浊度反而下降;加入少量单宁酸即可让酒体浊度达到30%以上;在酒样中加入铁盐,酒体的浊度会不断增加,直至产生大量沉淀;而加入蔗糖对酒体的浊度基本没有影响.实验结果与数据分析表明,黄酒中的蛋白质与多酚所形成的缔合物是影响酒体非生物稳定性的最主要因素.  相似文献

Despite their potential health benefits, the controversial nature surrounding the use of GM technology in biofortified crops remains a subject of discussion. This paper investigates the role of information on willingness‐to‐pay for folate‐biofortified rice in a Chinese folate‐deficient region. We conducted second price auctions with 252 women of childbearing age, split up into two target groups based on street (n = 132, non‐student sample) or school auctions (n = 120, student sample). Notwithstanding a general positive effect of folate‐related information (i.e. content, benefits and regional situation), evidence reveals that the non‐student sample is less concerned about GM technology. The results also provide insight into serial position effects in conflicting GM information. Whereas participants in the non‐student sample are more prone to a primacy bias when receiving both positive and negative information, an alarmist reaction is observed in the student sample. This study highlights the need for segmented, targeted communication strategies on biofortification.  相似文献

How much does a dramatic increase in technology improve healthcare quality in an upper middle‐income country? Using rich vital statistics on infant health outcomes, this study evaluates the effect of introducing technologically advanced perinatal hospitals in 24 regions of Russia on infant mortality during the period 2009–2013. A 7‐year aggregate panel dataset reveals that opening a perinatal centre corresponds to infant mortality reduction by 3.8 percent from the baseline rate, neonatal (0–28 day) mortality by 7 percent and early neonatal (0–6 day) mortality by 7.3 percent. We find that the perinatal centres help to save 263 additional infant lives annually, ranging from 3 to 25 lives in regions with different birth rates. However, we further find that an average cost per life saved is 52 million rb (or 2.6 million 2014 PPP USD), which is much higher than the cost of similar interventions in the United States.  相似文献

Using non‐parametric methods, we estimate the foregone rents due to credit, allocative, and technical inefficiencies of subsistence farmers in Southern India. The lost rents are estimated directly from the Nerlovian efficiency index, and the results suggest the largest foregone rents derive from allocative inefficiencies and then credit inefficiencies. Also, results suggest that farms without well access experience larger losses than those with well access. Econometric results suggest education, the presence of tank water management efforts, and well access influence the level of foregone rent due to allocative and Nerlovian inefficiencies. Educational activities and policies to encourage better management of tanks are considered important for lowering the foregone losses.  相似文献
