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...

This study considers a quantity discount problem between a single seller (poultry famer) and two buyers (retailers). The poultry farmer’s inventory level increases due to the increase in the weight of the fowls. The retailers purchase fresh chicken meat from the poultry farmer, the inventory levels of the retailers are therefore depleted due to the combined effects of its demand and deteriorati...

It explores an inventory system with noninstantaneous replenishment under conditions of permissible delay in payments. In practice, the supplier allows a certain fixed credit period to settle the account for stimulating retailer’s demand. Besides, the supplier can offer cash discount to encourage ret...

The use of linear wholesale price contract has long been recognized as a threat to achieving channel effciency. Many formats of nonlinear pricing contract have been proposed to achieve vertical channel coordination. Examples include two-part tariff and quantity discount.

We investigate whether superstitious beliefs held directly by only a fraction of the population affect market equilibrium. Using data from multiracial Singapore, we find that apartments whose unit numbers end with 8, an auspicious number for Chinese, are sold at 0.9% premium, whereas those that end with 4, an inauspicious number for Chinese, are sold at 1.5% discount. The discount for inauspici...

A normalized gaussian network (NGnet) (Moody & Darken, 1989) is a network of local linear regression units. The model softly partitions the input space by normalized gaussian functions, and each local unit linearly approximates the output within the partition. In this article, we propose a new on-line EMalgorithm for the NGnet, which is derived from the batch EMalgorithm (Xu, Jordan, &Hinton 19...

An auctioneer sells a single unit to a group of bidders using a second price auction. A subset of these bidders possess a coupon entitling them to a discount off the winning bid in the event they win the auction. Bidders without the coupon are at a disadvantage relative to the situation when nobody has any coupons. Therefore, in a loose sense, these bidders end up sponsoring the coupon, at leas...
