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...

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....

People adjust to the risks presented by natural disasters in a number of ways; they can move out of harms way, they can self protect, or they can insure. This paper uses Hurricane Andrew, the largest U.S. natural disaster prior to Katrina, to evaluate how people and housing markets respond to a...

Efforts to measure people’s responses to spatially delineated risks confront the potential for correlation between these risks and other, unobserved characteristics of these locations. The possibility of correlation arises in part because individuals observe other locational attributes that...
