This paper studies whether pro-environmental consumption choices are consistent with utility maximization and what role the consumption behavior of reference persons and one’s own past behavior play in this context. By combining data on individuals’ pro-environmental consumption from a unique data set with data on subjective well-being, we find that people could attain higher well-being (utilit...
Over-estimation of willingness to pay in contingent markets has been attributed largely to hypothetical bias. One promising approach for avoiding hypothetical bias is to tell respondents enough about such bias that they self-correct for it. A script designed for this purpose by Cummings and Taylor was used in hypothetical referenda that differed in payment amount. In comparisons with behavior o...
Bu çalışmada, elyaf bor fiber takviyeli prepreglerin (Specialty Materials 5505 Boron Epoxy Prepreg Tape) epoksi reçine (Hexcel RTM6) kullanılarak serim yöntemi metodu ile tabakalı kompozit malzeme üretilmiştir. Üretilen malzemeler 9 kat olacak şekilde nano ilaveli ve olmayacak iki farklı hazırlanmıştır. Bir grup numunede sadece kullanılırken diğer içerisine deneme (akışkanlığa bakılarak) % 0.07...
This article investigates the impact of renewable energy consumption and natural resource depletion on environmental degradation from 1990 to 2014. The analysis this study is distributed into three parts, developing country analysis, developed complete sample analysis. An insignificant relation has found between in case but vice-versa countries. Fossil fuel a positive significant Renewable nega...
A major concern with tradable emission permits is that stochastic permit prices may reduce a firm’s incentive to invest in abatement capital or technologies relative to other policies such as a fixed emissions charge. However, under efficient permit trading, the permit price uncertainty is caused by abatement cost uncertainties which affect investment under both permit and charge policies. We d...
Within the self-consistent constraint Skyrme-Hartree-Fock+BCSmodel (SHF+BCS), we found equilibrium toroidal nuclear density distributions in the region of super-heavy elements. For nuclei with a sufficient oblate deformation (Q20 ≤ -200 b), it becomes energetically favourable to change the genus of nuclear surface from 0 to 1, i.e., to switch the shape from a biconcave disc to a torus. The ener...
We derive a general framework for cost-benefit analysis and social discounting in a setting with intertemporally dependent preferences. Here, the marginal contribution of an additional unit of consumption in some period depends on what is consumed in the other periods. We use a simple model of history dependent preferences to analyze how habit formation affects the social rate of discount. Gett...
In rural economies with missing or incomplete markets, idiosyncratic risk is frequently pooled through informal networks. Idiosyncratic shocks, however, are not limited to private goods but can also restrict an individual from partaking in or benefitting from a collective activity. In these situations, a group must decide whether to provide insurance to the affected member. In this paper, we de...
Many renewable resources are in intergenerational common pools, exploited by one generation after another. In our experiment, the stock available to each generation depends on the extent of exploitation by previous generations and on resource’s growth rate, which is either ‘‘slow’’ or ‘‘fast.’’ Subjects show altruistic restraint in exploitation, but not enough to achieve the social optimum. The...
A standard result in the literature on environmental economics is that efficient environmental policies regulating transboundary pollution will be adopted only if there is interjurisdictional coordination. Efficient policies can be adopted as a result of interregional treaties or mandated by a central authority. The present paper demonstrates that if there is perfect population mobility between...
