In the standard search problem there is an infinite pool of items whose distribution of values is known. A decision maker draws an item from the pool, observes its value, and decides whether to keep it or to draw another item. He can keep only one item, and he seeks the item with the largest...

A common myth/conception, based upon the notion of increasing returns to scale in R&D activity, is that large firms account for a disproportionate share of innovations. In this paper we consider three types of informational returns to scale (cheaper, faster, and better) and examine the impact of...

When managing projects with considerable uncertainty, such as those arising in construction, defense, and new product development, it is customary for a manufacturer (project manager) to offer contracts under which each supplier (contractor) receives a prespecified payment when she completes her...

In the design of procurement contracts, cost sharing, wherein the contractor receives a fixed fee plus a fraction of his cost, is common when the cost for completing the project is uncertain. We determine the best cost-sharing contract between a risk-neutral project manager and a risk-averse...

We examine a game-theoretic model of a two-firm R&D race in which expenditures on R&D and the concomitant increase in experience/learning enable the firms to increase their probability of discovering an invention. The learning process is stochastic. It generates a unique subgame-perfect...

An individual is repeatedly offered the opportunity to invest in a risky asset whose return distribution is unknown. Because the return distribution is constant over time, however, he is able to learn about that distribution by observing investment outcomes. Results are presented regarding the...
