Nowadays, purchasing decisions are increasingly considering both tangible and intangible factors that in supplier selection. If suppliers have capacity or other different constraints, the problem is to identity the potential suppliers and to allocate the optimal order quantity among the selected suppliers. In this paper an integrated model of analytic hierarchy process (AHP) and preemptive goal...

INTRODUCTION Given that little is known about the price-related cigarette brand preferences of youths, the current study seeks to characterise cigarette brand preferences and examine factors associated with smoking discount or native cigarette brands among Canadian youths who are current smokers. METHODS This study used nationally representative data collected from 71,003 grade 5-12 students ...

The aim of this paper is to find a suitable discount function able to describe the progression of a certain addiction or disease under treatment as a discounting process. In effect, a certain indicator related to a disease decays over time in a manner which is mathematically similar to the way in which discounting has been modeled. We analyze the discount functions observed in experiments which...

In this investigation, we test whether temporal discounting is domain-specific (i.e., compared to other people, can an individual have a relatively high discount rate for one type of reward but a relatively low discount rate for another?), and we examine whether individual differences in the types of rewards one finds tempting explain domain-specificity in discount rates. Adults discounted dela...

Time preferences are a dominant influence in cost-benefit analyses of long-term issues such as climate change. FUND, a model for optimal emission control, is used to spell out this influence. Classic discounting at various rates is contrasted with Heal discounting where the discount factor depends logarithmically on the time distance (it does linearly in the classic case), and Rabl discounting ...

This paper investigates the impact of store location, a retailer's most costly and long-term marketing mix decision, on retailer revenues. We estimate models of consumer spending at the leading packaged goods retailers in a metropolitan market based on two dimensions of retail location: (i) proximity to consumers, i.e., travel times, and (ii) proximity to other stores, i.e., agglomeration. Both...

Modern finance theory is based on the competitive market paradigm (see Duffie 1992, Jarrow and Turnbull 1996). The competitive market paradigm has two implicit assumptions. The first is that security markets are perfectly elastic—that is, traders act as price takers. Price takers believe that they can buy and sell as many shares of a security as they wish without changing the price. The second ...
