In this paper we develop new methods for estimating causal effects in settings with panel data, where a subset of units are exposed to a treatment during a subset of periods, and the goal is estimating counterfactual (untreated)…
The contextual bandit literature has traditionally focused on algorithms that address the exploration-exploitation tradeoff. In particular, greedy algorithms that exploit current estimates without any exploration may be sub…
Framework agreements (FAs) are procurement mechanisms commonly used by buying agencies around the world to satisfy demand that arises over a certain time horizon. This paper is one of the first in the literature that provides a…
We study the convergence of the predictive surface of regression trees and forests. To support our analysis we introduce a notion of adaptive concentration for regression trees. This approach breaks tree training into a model…
In this paper we introduce a new computationally tractable framework for Ericson and Pakes (1995)- style dynamic oligopoly models that overcomes the computational complexity involved in computing Markov perfect equilibrium (MPE)…
A state with climate policy may impose a tax on imported products for greenhouse gas emissions that occur in production and transportation to its border (a so-called border adjustment). A buyer may voluntarily commit to offset its…
Recent Medicare legislation has been directed at improving patient care quality by stopping reimbursement of hospital-acquired conditions (HACs). However, this policy may be undermined if some providers respond by upcoding, a…
Currently available medication for treating many chronic diseases is often effective only for a subgroup of patients, and biomarkers accurately assessing whether an individual belongs to this subgroup do not exist. In such…
We study sourcing in a supply chain with three levels: a manufacturer, Tier 1 suppliers, and Tier 2 suppliers prone to disruption from, e.g., natural disasters like earthquakes or floods. The manufacturer may not directly dictate…
This paper proposes a Combined Method (combining fluid model estimators and statistical learning) to forecast the wait time for low-acuity patients in an Emergency Department, and describes the implementation of the Combined…
Governments are beginning to mandate that firms disclose information about social and environmental impacts in their supply chains (e.g., regarding conflict minerals and greenhouse gas emissions). This paper shows that such a…
This paper studies the endogenous formation of supply chain networks when procurement is subject to disruption risk. We argue that the presence of non-convexities in the chain (e.g., due to non-convex production technologies or…
We study the interplay between financial covenants and the operational decisions of a retailer that obtains financing through a secured, inventory-based lending contract. We characterize how leverage affects dynamic inventory…
A new class of online services allows internet media sites to direct users from articles they are currently reading to other content they may be interested in. This process creates a “browsing path” along which there is potential…
Random graph generation is an important tool for studying large complex networks and recently has been extensively used by biologists, computer scientists, economists, electrical engineers, and mathematical sociologists. Despite…
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…
Governments are beginning to mandate that firms disclose information about social and environmental impacts in their supply chains (e.g., regarding conflict minerals and greenhouse gas emissions). This paper shows that such a…
We study the evolution of industries in terms of three interrelated key themes that together form an analytical lens. The first-theme strategy and strategic dynamics raises the question of how companies can gain, sustain, or…
We incorporate a stochastic cost for emissions into Venables’ widely-used model of international trade for a single product. Region 1 has climate policy and Region 2 does not. Each region has a distinct variable cost of production…
