The past decade has witnessed significant movements to push manufacturing back to developed countries. Such movements call for raising import tariffs and increasing consumers' valuation on products made from locally sourced components. These factors are believed to motivate local sourcing for...

Given the difficulty to reach a global quantity commitment to control the carbon emissions, a globally uniform price commitment is proposed to tackle the current environmental issues. In this paper, we take an operations perspective to understand the impact of both the cap-and-trade policy...

Exponential bandits are widely adopted in economics and marketing due to their tractability. This paper analyzes the one-agent multi-armed account of exponential bandits, where the agent dynamically selects arms to maximize total payoff. We motivate our base model by examples with arms being of...

In this paper we study doubly robust estimators of various average treatment effects under unconfoundedness. We unify and extend much of the recent literature by providing a very general identification result which covers binary and multi-valued treatments; unnormalized and normalized weighting;...

In this paper we study the finite sample and asymptotic properties of various weighting estimators of the local average treatment effect (LATE), several of which are based on Abadie (2003)’s kappa theorem. Our framework presumes a binary endogenous explanatory variable (“treatment”) and a...

We revisit the problem of estimating the local average treatment effect (LATE) and the local average treatment effect on the treated (LATT) when control variables are available, either to render the instrumental variable (IV) suitably exogenous or to improve precision. Unlike previous...
