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...

We optimize a large country's currency supply network for its central bank. The central bank provides currency to all branches (who in turn serve consumers and commerce) through its network of big vaults, regional vaults, and retail vaults. The central bank intends to reduce its total...

We study a retailer's sourcing contract when the supplier's reservation profit (offered by his outside options) depends on his cost, which is privately known to only the supplier. An interesting discovery from our analysis is that supply chain coordination may be achieved despite the...

We study sourcing decisions of price-setting and price-taking firms with two unreliable suppliers, where a price-setting firm sets the retail price after the supply uncertainty is resolved and a price-taking firm takes the retail price as given. We investigate the impacts of market conditions,...

Coordinating contracts have been extensively researched in supply chain management. In this retrospect, we systematically review the profit allocation, decision sequence, and compliance aspects of these contracts. In addition to the existing concepts in the literature, we propose the notion of...

This paper studies the issue of coordinating equipment maintenance operations with capital investment strategy in the presence of random equipment failures. This problem represents an important extension of the celebrated Kamien and Schwartz (KS) paper published in Management Science. The...

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 study the capacity investment strategy of a manufacturer who sells his product on a live-streaming shopping platform. The manufacturer first decides the production capacity, then the platform decides her commission, and finally the manufacturer sets the retail price. The platform has an...

We consider a cooperative advertising channel consisting of a manufacturer selling its product through a retailer in competition with another independent retailer. The manufacturer subsidizes its retailer's advertising only when a certain threshold is positive. Moreover, the manufacturer's...
