中国都市住民における生活ごみの分別意識，分別行動及びごみ減量への支払意識 : 湖南省長沙市を事例に (I)
No full textChina has been struggling with waste classification for decades, even after the mandatory implementation of relevant policy in 2017. However, the causes of the failing performance of waste classification in developing countries attract little scholarly attention. A recent literature review also identified a failure to classify waste in developing countries, noting that its causes have attracted little scholarly interest. In this paper, we would like to examine the current situation and issues of policies for classifying household waste in China's urban sector. In this paper, we conducted a questionnaire survey of residents in Changsha City, Hunan Province, examined their awareness of waste classification, classifying behavior, and their awareness of paying for waste reduction, elucidated the factors that affect them, and estimated the amount of willing to pay (WTP) for waste reduction. In this paper, endogenous factors are more significant influencing behaviors than exogenous factors
空売り規制が資産価格の下落と変動を大きくすることを示す一理論モデル
No full text資産価格はしばしばファンダメンタル・バリューから乖離し，時として金融市場は資産価格の大きな下落や変動に見舞われる．急激な資産価格変動を緩和するための措置として，多くの国々で空売り規制が導入されてきた．本稿は空売り規制の導入が資産価格に与える影響を分析する．私的情報や価格支配力を持つ投資家と私的情報を持たない価格受容的な投資家が混在する資産市場を想定する．空売り規制の導入が事前に予期されていない場合，空売り規制が資産価格をファンダメンタル・バリューから乖離させることが明らかになった．これは資産価格の変動を大きくすることにもつながる．とりわけ資産価格の下支えが望まれるような下落相場の状況では，空売り規制の導入はより一層の価格下落をもたらすことになる
Willingness to incur private costs for climate adaptation? Public support for undergrounding electricity transmission lines in California
No full textClimate mitigation policies face a political challenge because they tend to impose local costs to create a global public goods benefit. While climate adaptation tends to create local benefits while imposing local costs, the benefits tend to accrue in the long run while costs are incurred in the short run. Might this time inconsistency challenge get abated when individuals learn of different rationales for adaptation policies or have experienced natural disasters? To reduce electricity outages from extreme weather events such as wildfires and storms, burying transmission lines has gained policy traction. But to pay for it, households will probably face higher energy bills. In a survey experiment in California (N = 1484), we randomly exposed respondents to three treatment frames that highlight different co-benefits of undergrounding lines: decarbonization (electrification is crucial for climate transition), equity (electricity outages burden low-income households), and national pride (the US lags behind Western Europe in undergrounding lines). To our surprise, the decarbonization frame reduced support levels, while other frames were not significant. We find that the frequency of experiencing electricity outages in the last 12 months, and property damage from extreme weather events (within 200 miles) increases support for undergrounding lines
