A series of polyene–diphenylaniline based organic dyes (coded as D5, D7, D9 and D11) have been reported for the application in ionic liquid electrolyte based dye-sensitized solar cells. The effects of substitution of organic dyes on the photovoltaic performance have been investigated, which show addition of methoxy groups on the triphenylamine donor group increases short-circuit current, open-c...

For better understanding of conformational stability of the dipeptide model HCO—Gly—L—Leu—NH2,ab initio and DFT computations at HF/6-31G(4 6-311++G(d,p) and B3LYP/6-31G(d) levels oftheory were carried out. Geometry optimization of the dipeptide within the leucine (Leu) side chainangles (x2 ,x2) resulted in three stable conformations as followings: anti-anti, the most stable one,(Xi = 180°, x2 =...

We consider a broad class of intertemporal economic problems and characterize the short-run long-run responses demand for good to permanent increase in its market price. Depending on interplay between self-productivity time discounting, we show that dynamic substitution effects can generate price elasticities opposite signs short run long run.

People are sometimes risk-averse in gains but risk-loving in losses. Such behavior and other anomalies underlying prospect theory arise from a model of local status maximization in which consumers compare their wealth with other consumers of similar wealth. This social explanation shares key features with the psychological explanation offered by Kahneman and Tversky. JEL Classification: D81, D11

Concern for individual consumption relative to per capita consumption can induce a fear of falling behind which increases precautionary savings. This fear intensifies as societal income growth increases, allowing for a positive effect of growth on savings rates. JEL classifications: E21, D11, D91.

This paper shows that even if all consumers face search costs, if these are below a certain level dependent upon the firm numbers and demand elasticity, the Diamond-type equilibrium with all prices at the monopoly level fails to exist. JEL Classification: D83, D11,

We consider preference relations over information that are monotone: more information is preferred to less. We prove that, if a preference relation on information about an uncountable set of states of nature is monotone, then it is not representable by a utility function. JEL Classification: C70, D11, D80
