Modeling inter-temporal choice is a key problem in both computer science and economic theory. The discounted utility model of Samuelson is currently the most popular model for measuring the global utility of a time-series of local utilities. The model is limited by not allowing the discount function to change with the age of the agent. This is despite the fact that many agents, in particular hu...

OBJECTIVES Stress hormones have been associated with temporal discounting. Although time-discount rate is shown to be stable over a long term, no study to date examines whether individual differences in stress hormones could predict individuals' time-discount rates in the relatively distant future (e.g., six month later), which is of interest in neuroeconomics of stress-addiction association. ...

We study the dynamic pricing decisions for competitive network service providers. We assume that each competing firm follows a three-part pricing scheme, which consists of an ongoing membership fee, a usage fee for communications within the networks, and another usage fee for communications across the networks. The difference between the two usage fees is the network-based price discount that a...

Many information retrieval (IR) metrics are top-heavy, and some even have parameters for adjusting their discount curve. By choosing the right metric and parameters, the experimenter can arrive at a discount curve that is appropriate for their setting. However, in many cases changing the discount curve may not change the outcome of an experiment. This poster considers query-level directional ag...

This paper extends the common inclination for people to value losses more than gains to the measurement of time preferences. This extension provides testable predictions of a pattern of discount rates that includes use of higher rates to discount the value of future gains than future losses. Two empirical tests, one for differing valuations of future outcomes and the other for varied discount r...

In this paper, a single-vendor, single-buyer supply chain for fixed lifetime product is considered. We propose models to analyze the benefit of coordinating supply chain through quantity discount strategy. Under the proposed strategy, the buyer is requested to alter his current order size such that the vendor can benefit from lower costs, and quantity discount is offered by the vendor to compen...

We estimate individual discount rates with respect to time streams of money using controlled laboratory experiments. These discount rates are elicited by means of field experiments involving real monetary rewards. The experiments were carried out across Denmark using a representative sample of 268 people between 19 and 75 years of age. Individual discount rates are estimated for various househo...

The purpose of this study is to examine the effects disclosing sales commissions pertaining an influencer discount code on perceived sincerity and attitude toward using code. In first study, consumers participated in a two-cell (commission disclosure: absent vs. present) between-subjects experimental design. second two by (discount level: low high) findings Study 1 demonstrate that commission d...

Although there is a widespread agreement on the need to discount future costs in monetary-based evaluation techniques of long-term transportation projects, there is less agreement on the specific discount rate that should be employed in the analysis. The choice of the discount rate is ultimately a policy decision; but even when the philosophical approach is set by the policy makers and a genera...

the first spoken dialogue system developed for the persian language is introduced. this is a ticket reservation system with persian asr and nlu modules. the focus of the paper is on learning the dialogue management module. in this work, real on-line training data are used during the learning process. for on-line learning, the effect of the variations of discount factor (g) on the learning speed...
