Switchback Price Experiments with Forward-Looking Demand
Yifan Wu, Ramesh Johari, Vasilis Syrgkanis +1
Switchback experiments are widely used in pricing applications. We consider a retailer running such an experiment for the price of a single product, with infinite supply. In each p…
When Does Interference Matter? Decision-Making in Platform Experiments
Ramesh Johari, Hannah Li, Anushka Murthy +1
This paper investigates decision-making in A/B experiments for online platforms and marketplaces. In such settings, due to constraints on inventory, A/B experiments typically lead…
Price Experimentation and Interference
Ramesh Johari, Orrie B. Page, Gabriel Y. Weintraub
In this paper, we examine the biases that arise when firms run A/B tests on continuous parameters to estimate global treatment effects on performance metrics of interest; we partic…
Bidders' Responses to Auction Format Change in Internet Display Advertising Auctions
Shumpei Goke, Gabriel Y. Weintraub, Ralph Mastromonaco +1
We study actual bidding behavior when a new auction format gets introduced into the marketplace. More specifically, we investigate this question using a novel dataset on internet d…
Interference, Bias, and Variance in Two-Sided Marketplace Experimentation: Guidance for Platforms
Hannah Li, Geng Zhao, Ramesh Johari +1
Two-sided marketplace platforms often run experiments to test the effect of an intervention before launching it platform-wide. A typical approach is to randomize individuals into t…
The Social Divide of Social Distancing: Shelter-in-Place Behavior in Santiago during the Covid-19 Pandemic
Aldo Carranza, Marcel Goic, Eduardo Lara +6
Voluntary shelter-in-place directives and lockdowns are the main non-pharmaceutical interventions that governments around the globe have used to contain the Covid-19 pandemic. In t…
Experimental Design in Two-Sided Platforms: An Analysis of Bias
Ramesh Johari, Hannah Li, Inessa Liskovich +1
We develop an analytical framework to study experimental design in two-sided marketplaces. Many of these experiments exhibit interference, where an intervention applied to one mark…
Third-Degree Price Discrimination Versus Uniform Pricing
Dirk Bergemann, Francisco Castro, Gabriel Weintraub
We compare the profit of the optimal third-degree price discrimination policy against a uniform pricing policy. A uniform pricing policy offers the same price to all segments of th…
Quality Selection in Two-Sided Markets: A Constrained Price Discrimination Approach
Bar Light, Ramesh Johari, Gabriel Weintraub
Online platforms collect rich information about participants and then share some of this information back with them to improve market outcomes. In this paper we study the following…
Mean Field Equilibrium: Uniqueness, Existence, and Comparative Statics
Bar Light, Gabriel Weintraub
The standard solution concept for stochastic games is Markov perfect equilibrium (MPE); however, its computation becomes intractable as the number of players increases. Instead, we…
Equilibria of Dynamic Games with Many Players: Existence, Approximation, and Market Structure
Sachin Adlakha, Ramesh Johari, Gabriel Y. Weintraub
In this paper we study stochastic dynamic games with many players; these are a fundamental model for a wide range of economic applications. The standard solution concept for such g…
