We study the problem of modeling purchase of multiple items and utilizing it to display optimized recommendations, which is a central problem for online e-commerce platforms. Rich personalized modeling of users and fast computation of optimal products to display given these models can lead to...

In this paper, we develop a new optimization model for capital rationing with uncertain project returns. Our model maximizes the probability of meeting a pre-defined target return by selecting a feasible set of projects subject to budget constraints in multiple time periods. We employ a...

We provide a revealed preference analysis of the transferable utility hypothesis, which is widely used in economic models. First, we establish revealed preference conditions that must be satisfied for observed group behavior to be consistent with Pareto efficiency under transferable utility....
