Assessing financial product solutions to America's retirement income planning: A closer look at annuity lifetime withdrawal guarantees and target date mutual funds
Discrete choice models are appealing for airline revenue management (RM) because they offer a means to profitably exploit preferences for attributes such as time of day, routing, brand, and price. They are also good at modeling demand for unrestricted fare class structures, which are widespread throughout the industry. However, there is little empirical research on the practicality and effectiveness of choice-based RM models. Toward this end, we report the results of a study of choice-based RM conducted with a major U.S. airline.
We consider a general infinite horizon inventory control model which combines demand and supply risks and the firm's ability to mitigate the supply risks by diversifying its procurement orders among a set of N potential suppliers. Supply risks arise because only a random percentage of any given replenishment order is delivered as useable units. The suppliers are characterized by the price they charge and the distribution of their yield factor.

A widely used model in the online advertising industry is one where advertisers pre-purchase a reservation package of online inventory on content sites owned by publishers (e.g., CNN, amazon, etc.). Sales representatives, acting on behalf of publishers, sell inventory (impression) bundles of various types (text, video, multimedia, etc.) while trying to meet advertisers' expectations.
Economics is the study of how scarce resources are allocated. Operations research studies how to accomplish goals in the least costly manner. These fields have much to offer each other in terms of challenging problems that need to be solved and the techniques to solve them. This was the case after World War II, partly because the individuals who went on to be the leading scholars in economics and operations research worked together during WWII. In fact, the two fields share many early luminaries, including Arrow, Dantzig, Holt, Kantorovich, Koopmans, Modigliani, Scarf, and von Neumann.
