Some special events such as adjustments of executives can cause the disruption social welfare responsibility degree (SWRD for short) firm's decision-maker, which may further influence price and service-level decisions supply chain coordination. However, in field management, there are very limited studies on SWRD disruption. Facing potential disruption, we develop game-theoretic models to invest...

This paper contributes to the study of tacit collusion by analyzing infinitely repeated multiunit uniform price auctions in a symmetric oligopoly with capacity constrained firms. Under both the Market Clearing and Maximum Accepted Price rules of determining the uniform price, we show that when each firm sets a price-quantity pair specifying the firm’s minimum acceptable price and the maximum qu...

Is the cost of living higher for the poor? Recent studies based on unit values (the ratio of expenditure to quantity) suggest that poor households pay substantially higher prices because liquidity constraints force them to purchase goods in small quantities and not realize bulk discounts. Unit values are subject to several biases and reflect economizing choices made by households, so they may n...

In this article, Professor Allen Blair examines the preeminent role of exclusivity in open-quantity contracts under the Uniform Commercial Code (“UCC”). Although the text of the UCC does not mandate that open-quantity contracts be exclusive, the vast majority of courts considering the issue have held that exclusivity is necessary to prevent such contracts from failing for lack of mutuality of o...

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 ...

The inventory models analyzed in this paper explore the problem in which the lead time and ordering cost reductions are inter-dependent in the continuous review inventory model with backorder price discount. The objective is to minimize total related cost by simultaneously optimizing the order quantity, reorder point, lead time and backorder price discount. Moreover, we assume that the mean and...

In this paper we experimentally investigate how the allocation of inventory risk in a two-stage supply chain affects channel efficiency. We first evaluate two common wholesale price contracts that differ in which party incurs the risk associated with unsold inventory; a push contract in which the retailer incurs the risk, and a pull contract in which the supplier incurs the risk. Our experiment...

The purpose of this study is to investigate the impact of trade credit in the inventory system. 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...

This study examined the incidence and determinants of quantity price discounts and quantity price surcharges in the German food sector through a bivariate probit, using recent consumer scanner survey data. Selectivity bias was corrected for in estimating the degree of quantity price surcharge and quantity price discount, using Heckman’s procedure. The findings reveal that almost 10% of the inve...
