We study a firm's optimal pricing policy under price commitment. The firm's objective is to maximize its long-term average revenue given a steady arrival of strategic customers. In particular, customers arrive over time, are strategic in timing their purchases and are heterogeneous along two...

Problem definition. Motivated by the debate around drivers' welfare in on-demand transportation, we propose a framework to evaluate current practices and also possible alternatives. We study a setting in which riders seek drivers and a platform facilitates such matches over the course of the...

In this work, we study data-driven decision-making and depart from the classical identically and independently distributed (i.i.d.) assumption. We present a new framework in which historical samples are generated from unknown and different distributions, which we dub heterogeneous environments....

Many factors introduce the prospect of changes in the demand environment that a firm faces, with the specifics of such changes not necessarily known in advance. If and when realized, such changes affect the delicate balance between demand and supply and thus current prices should account for...

The role of assortment planning and pricing in shaping sales and profits of retailers is well documented and studied in monopolistic settings. However, such a role remains relatively unexplored in competitive environments. In this paper, we study equilibrium behavior of competing retailers in...

We consider a non-stationary variant of a sequential stochastic optimization problem, where the underlying cost functions may change along the horizon. We propose a measure, termed variation budget, that controls the extent of said change, and study how restrictions on this budget impact...

Managing shipping vessel profitability is a central problem in marine transportation. We consider two commonly used types of vessels - liners (ships whose routes are fixed in advance) and trampers (ships for which future route components are selected based on available shipping jobs) - and...
