DEA Model with Shared Resources and Efficiency Decomposition
By: Yao Chen, Juan Du, H. David Sherman and Joe Zhu
Data envelopment analysis (DEA) has proved to be an excellent approach for measuring performance of decision making units (DMUs) that use multiple inputs to generate multiple outputs. In many real world scenarios, DMUs have a two-stage network process with shared input... View Details

Unexploited Efficiencies in Higher Education
By: Henry C. Eyring
In "Unexploited Efficiencies in Higher Education," Henry C. Eyring argues that one way that the U.S. can compete globally in college attainment is to decrease cost-per-graduate. He explains how many stakeholders in higher education stand to benefit from unexploited... View Details

Oracle Efficient Private Non-Convex Optimization
By: Seth Neel, Aaron Leon Roth, Giuseppe Vietri and Zhiwei Steven Wu
One of the most effective algorithms for differentially private learning and optimization is objective perturbation. This technique augments a given optimization problem (e.g. deriving from an ERM problem) with a random linear term, and then exactly solves it.... View Details

Dynamic Pricing, Intertemporal Spillovers, and Efficiency
By: Alexander J. MacKay, Dennis Svartbäck and Anders G. Ekholm
Pricing technology that allows firms to rapidly adjust prices has two potential benefits.
Time-varying prices can respond to high-frequency demand shocks to generate greater revenues,
and they can also be used to smooth out demand to reduce costs. Using data... View Details

Approximating the Efficiency Gain of Tax Reforms
By: Jerry R. Green and Eytan Sheshinski
Proper analysis of tax reform requires evaluation of the welfare effects induced by a change from one tax system to another. We present two methods for estimating these changes using only local information pertaining to an initial equilibrium with distortive taxes. It... View Details

Competing Matchmakers: An Experimental Analysis
By: Tanjim Hossain, Dylan B. Minor and John Morgan
Platform competition is ubiquitous, yet platform market structure is little understood. Theory models typically suffer from equilibrium multiplicity—platforms might coexist or the market might tip to either platform. We use laboratory experiments to study the outcomes... View Details
