  • Efficient switchback experiments via multiple randomization designs
    Lorenzo Masoero, Guido Imbens, Thomas Richardson, James McQueen, Suhas Vijaykumar, Ido Rosen
    2023 Conference on Digital Experimentation @ MIT (CODE@MIT)
    2023
    Online A/B tests have become an indispensable tool across all the technology industry: if performed correctly, “online” experiments can inform effective decision making and product development. It should therefore not be surprising that Gupta et al. [2019] estimates that online businesses alone collectively run hundreds of thousands of experiments annually. Modern online experiments are often run in marketplaces

  • Cross-unit spillovers in A/B testing: Empirical evidence from ads
    Ronak Jain, Stefan Hut, Mahnaz Islam, Yao Pan
    2023 Conference on Digital Experimentation @ MIT (CODE@MIT)
    2023
    Randomized Control Trials (RCTs) are widely used across Amazon to causally estimate impacts of proposed feature changes, in order to make data-driven launch decisions. A key element of experimental design is the level of randomization, and the choice often relies on the cross-unit interaction structure. For instance, in the context of advertiser experiments, a treatment may affect the outcome of control

  • Value of stratification in cluster-randomized experiments
    Stefan Hut, Blake Mason, Mahnaz Islam, Lledo Esquerra
    2023 Conference on Digital Experimentation @ MIT (CODE@MIT)
    2023
    There are many experimental settings that may suffer from cross-unit (customers, seller, advertiser, etc.) spillovers, for instance through network effects. Such effects introduce bias and prevent the experimenter from drawing trustworthy insights on the data. One approach to dealing with such spillovers is to group units into clusters and randomize treatment status at the cluster level. Examples of clusters

  • The need for a durability index framework for electrical and electronic equipment to support a circular economy
    Hamidreza Habibollahi Najaf Abadi, Maxim Nikiforov, Aaron Krive, Jeffrey W. Herrmann, Mohammad Modarres
    ESREL 2023
    2023
    Enabling a circular economy aims to reduce the amount of global waste generated from electrical and electronic equipment, mitigate the associated risk to the ecosystem and human health, and address concerns over limited material resources. Durability is a critical concern because keeping products in use for a longer time should reduce resource consumption and waste. Assessing the durability of products

  • MNL-prophet: Sequential assortment selection under uncertainty
    Vineet Goyal, Salal Humair, Orestis Papadigenopoulos, Assaf Zeevi
    WINE 2023
    2023
    Due to numerous applications in retail and (online) advertising the problem of assortment selection has been widely studied under many combinations of discrete choice models and feasibility constraints. In many situations, however, an assortment of products has to be constructed gradually and without accurate knowledge of all possible alternatives; in such cases, existing offline approaches become inapplicable

US, WA, Seattle
The People eXperience and Technology Central Science (PXTCS) team uses economics, behavioral science, statistics, and machine learning to proactively identify mechanisms and process improvements which simultaneously improve Amazon and the lives, well-being, and the value of work to Amazonians. PXTCS is looking for an economist who can apply economic methods to address business problems. The ideal candidate will work with engineers and computer scientists to estimate models and algorithms on large scale data, design pilots and measure impact, and transform successful prototypes into improved policies and programs at scale. PXTCS is looking for creative thinkers who can combine a strong technical economic toolbox with a desire to learn from other disciplines, and who know how to execute and deliver on big ideas as part of an interdisciplinary technical team. Key job responsibilities The economists within PXTCS design and evaluate the systems that shape how Amazon's Operations workforce is hired, developed, recognized, and retained. They build predictive models, design causal experiments, and develop econometric frameworks that quantify tradeoffs and inform leadership decisions across talent programs. The team works at the intersection of mechanism design, causal inference, and applied measurement — partnering with applied scientists, product teams, and program leaders to embed science into the design of talent systems rather than evaluating them after the fact.
