This research explores the value of data sharing in a two-echelon, fresh product supply chain consisting of a retailer and manufacturer. Demand is stochastic and price sensitive. Decision-making is decentralized and the supply chain operates with a simple linear wholesale price contract. We...

This paper investigates the relationship between market conditions and the value and use of sourcing flexibility for service processes. We develop and analyze a series of models, and we derive expressions for the optimal switching decision, the value of the option to outsource, the value of the...

In this paper, we study price optimization with price-demand relationships captured by the paired combinatorial logit (PCL) model which overcomes restrictions of the well-studied multinomial logit (MNL) and nested logit (NL) models. The PCL model allows for choice-correlation and, like the NL...

Artemisinin combination therapy, the most effective malaria treatment today, is manufactured from an agriculturally derived starting material Artemisia annua. Artemisinin, the main ingredient in malaria medicines, is extracted from Artemisia leaves and used in the production of medicine for...

Accurate diagnosis directly impacts service quality and resource allocation in healthcare operations. Advanced medical tests can improve doctors' diagnostic accuracy, but they are usually financially costly or infeasible for some patients. To achieve decent diagnostic performance when advanced...

The exact mechanism as to how last-mile supply network (LMSN) configuration influences performance has been relatively undeveloped, and with mixed results in the extant literature. This paper argues the difficulty in arriving to a convergent understanding because of a missing link that connects...

A comprehensive empirical investigation is carried out to ascertain the import-reducing effect of trade protection barriers. We first present a statistical summary of the status of global trade protection. Then, based on a monopolistic competition trade model and 1994 cross-country data on trade...

Through the use of a multivariate cointegration and error-correction model, this study investigates the short- and long-run relationship over the past two decades between fiscal expenditure policy and non?oil real GDP growth in member countries of the Gulf Cooperation Council (GCC). Despite the...

The paper examines the direction of causality between total government expenditure and revenue in oil-dependent GCC countries by utilizing a cointegration and error-correction modeling framework, and by calculating a variance decomposition analysis. In addition, it presents impulse responses to...

Inspired by the popularity of the advertising model at search engines, many online retailing platforms have added a new revenue stream of advertising (i.e., sponsored ads) to their traditional commission-based business model. While this new hybrid model is intuitively appealing, questions on its...
