Educational providers, such as those in the university sector and corporate learning, are under increasing pressure to enhance the pedagogical quality and technical richness of their course offerings while at the same time achieving improved return...

Recently, one of the most interesting topics in supply chain management (SCM) is the integrated vendor-buyer production-inventory problem, in which the critical issue is to determine economic lot size per shipment and deliveries. Most researches on this issue assume that products are screened and the process is perfect; however, screening errors (including type-I and type-II) may occur with imp...

In many cases, buyers must incur search costs to find the price of a product. This search cost affects the behavior of consumers, and through that, it affects the profit maximizing behavior of the firms.

As suppliers provide more value in today’s supply chains, eliciting supplier cost-reduction efforts and inducing supplier competition are two important levers for a buyer to reduce sourcing costs. In this paper, we study a buyer’s sourcing strategy considering supplier effort and competition. The buyer has two instruments in her strategy: the composition of the supply base and the contracting m...

Movie studios often have to choose among thousands of scripts to decide which ones to turn into movies. Despite the huge amount of money at stake, this process, known as “green-lighting” in the movie industry, is largely a guesswork based on experts’ experience and intuitions. In this paper, we propose a new approach to help studios evaluate scripts which will then lead to more profitable green...

We propose a model of firm reputation in which a firm can invest or disinvest in product quality and the firm’s reputation is defined as the market’s belief about this quality. We analyze the relationship between a firm’s reputation and its investment incentives, and derive implications for reputational dynamics. Reputational incentives depend on the specification of market learning. When consu...
