We study an economy in which the rate of change of population depends on population policy decisions. This requires population as well as capital as state variables. By showing the algebraic relationship between the shadow price of the population and the shadow price of the per capita capital...

We study sourcing and pricing decisions of a firm with correlated suppliers and a price-dependent demand. With two suppliers, the insight -- cost is the order qualifier while reliability is the order winner -- derived in the literature for the case of exogenously determined price and independent...

With the increasing awareness of the serious consequences of supply disruption risk, firms adopt various kinds of strategies to mitigate it. We consider a supply chain in which two suppliers sell components to two competing manufacturers producing and selling substitutable products. Supplier 1...

This paper investigates a platform service supply chain composed of a single supplier and a service platform that not only resells products but also may serve as an intermediary that connects the supplier to consumers directly. The service platform can improve the performance of the retail...

A commonly observed two-stage pricing strategy for a custom-made product involves a prepurchase entry fee for a potential consumer and a purchase price if he decides to buy the product. We solve and compare two settings: In the first, the firm does not commit in advance to the second-stage price...

We develop a general model for software development process and propose a policy to manage system coordination using system fault reports (e.g., interface inconsistencies, parameter mismatches, etc.). These reports are used to determine the timing of coordination activities that remove faults....

We study a two-period supply chain consisting of a manufacturer, who participates in a cap-and-trade scheme and faces an uncertain emission permit price, and a retailer, who sells the product from the manufacturer to consumer and faces a price-sensitive demand. In the face of uncertain future...

We consider a firm's sourcing problem from one reliable supplier and one unreliable supplier in two price setting scenarios. In the committed pricing scenario, the firm makes the pricing decision before the supply uncertainty is resolved. In the responsive pricing scenario, the firm's pricing...
