Time preferences are central to human decision making; therefore, a thorough understanding of their international differences is highly relevant. Previous measurements, however, vary widely in methodology, from questions answered on the Likert scale lottery-type questions. We show that these different measurements correlate large degree and they have common factor can predict broad spectrum var...

Time preference has a peculiar role in determining the level of economic activities. Time preferenceis the most important origin of interest rate. In this paper we study the founders and defenders'viewpoints about time preference and then we try to criticize them. It seems that discounting futureutilities is resulting from irrationality and it is ethically indefensible too. From mathematical as...

In the problem of …nding an e¢ cient allocation when agents’utilities are privately known, we examine the e¤ect of restricting attention to mechanisms using “demand queries,” which ask agents to report an optimal allocation given a price list. We construct a combinatorial allocation problem with m items and two agents whose valuations lie in a certain class, such that (i) e¢ ciency can be obtai...

We consider how to combine the preferences of multiple agents despite the presence of incompleteness and incomparability in their preference orderings. An agent’s preference ordering may be incomplete because, for example, there is an ongoing preference elicitation process. It may also contain incomparability, which can be useful, for example, in multi-criteria scenarios. We focus on the proble...

background : the present study aimed to provide better insight on methodological issues related to time preference studies, and to estimate private and social discount rates, using a rigorous systematic review and meta-analysis. methods : we searched pubmed, embase and proquest databases in june 2013. all studies had estimated private and social time preference rates for health outcomes through...

the rate of time preference plays an important role in discounting instantaneous utility in economic growth models and also in calculating social discount rate in cost-benefit analysis. in empirical researchers, this rate is assumed to be constant. however, the rate of time preference might vary over time. this paper develops a new algorithm to estimate this rate as a varied coefficient for the...

Preference value means livestock preference to eat some plants relative to other plants or species. Accordingly, by studying the preference values, the range managers could determine the rangelands grazing capacity to achieve the optimum performance of livestock and to guarantee the stability of rangeland ecosystem. The objective of this study was to determine the preference value of perennial ...
