In a two-stage serial supply chain, a periodic flexible policy (PF policy) allows the retailer to receive fixed orders that may depend on demand history in one period of the ordering cycle and order freely in other periods. Existing literature has shown that certain PF policies can significantly...

We ask whether option prices contain information on the likelihood and direction of jumps in the underlying stock prices. Applying the partial least squares (PLS) approach to the entire surface of the implied volatilities (IV), we show that option prices can successfully predict downward jumps...

A principal has n homogeneous objects to allocate to I n agents. The principal can allocate at most one good to an agent and each agent values the good. Agents have private information about the principal's payoff of allocating the goods. There are no monetary transfers but the principal can...

Consider the ordinary transportation problem with the objective to minimize the cost of transporting a single commodity from M warehouses to N demand locations. Each warehouse i has a finite capacity ki. We convert the above problem into a dual problem and construct a greedy algorithm to solve it

Motivated by our experience with a global company, we propose and study the concept of a semi-centralized supply chain and analyze its coordination issues. We focus on a supply chain consisting of a home plant and a foreign branch, both of which are under the same parent company but have...

This paper studies the single-warehouse assortment selection problem that aims to minimize the order fulfillment cost under the cardinality constraint. We propose two types of fulfillment-related cost functions, which correspond to different preferences toward spillover fulfillment and...
