It is well-known that the discount rate is crucially important for estimating the social cost of carbon, a standard indicator for the seriousness of climate change and desirable level of climate policy. The Ramsey equation for the discount rate has three components: the pure rate of time preference, a measure of relative risk aversion, and the rate of growth of per capita consumption. Much of t...

In this article, a finite horizon, multi product and multi period economic order quantity like seasonal items is considered where demand rate is deterministic and known but variable in each period. The order quantities of items come in batch sizes and the end of the period order quantity and, consequently, demand of customers are zero. In addition, storage space is constrained and the problem...

Climate change mitigation strategies, including efforts to reduce greenhouse gas emissions, are not specifically designed to improve human health but could potentially do so anyway. A review in this issue of EHP critically examines different models for estimating these so-called co-benefits and highlights improvements that could help assess which mitigation strategies are the most promising for...

the objective of this study was to develop a cost minimizing pattern for cube sugar and sugar transportation from production centers to refinement and storage centers and finally to distribution and consumption  centers in  fars province. producing centers are marvdasht (27.3%), eghlid (27.9%), fasa (11.3%), kavar (7.3%) and mamasani (20.2%). some of the province’s cube sugar and sugar is provi...

Background Several foreign trials indicated clinical benefits and cost-effectiveness of the lifestyle programs for patients with metabolic syndrome (MetS) but the economic benefit of such programs has not yet been evaluated in Thailand. Objective This study was aimed to assess the cost-effectiveness of the lifestyle modification program for Thai MetS patients compared with the usual care. Desig...

Low-cost providers have emerged as important players in many service industries, the most predominant being low-cost, or the so-called discount airlines. This paper presents models and results leading toward understanding the revenue management outlook for a discount pricing firm. A framework and model is formulated specifically for the airline industry, but is generalizable to low-cost provide...

We model the distortions that internal power struggles can generate in the allocation of resources between divisions of a diversified firm. The model predicts that if divisions are similar in the level of their resources and opportunities, funds will be transferred from divisions with poor opportunities to divisions with good opportunities. When diversity in resources and opportunities increase...
