This research investigates compound causes of the bullwhip effect (BWE) by considering an inventory system with multiple price-sensitive demand streams. Joint price and demand dynamics are captured by a vector time-series process that incorporates the stochastic co-movements in price and demand....

This paper shows that an ARMA demand generates an ARMA order history when ordering decisions are made based on an order-up-to policy. The order history preserves the autoregressive structure of the demand and transforms its moving average structure according to a simple algorithm. We apply this...

This paper reports the first attempt to measure the importance of controlling marine debris as an aesthetic characteristic of beaches and coastal area. The results are based on a contingent valuation survey designed to estimate the economic value people would place on controlling marine debris...
