Introduction
Two very interesting papers: Steering Technological Progress, by Korinek and Stiglitz Digital Adoption, Automation, and Labor Markets in Developing Countries, by Finkelstein Shapiro and Mandelman
Brief comments on each Overview of a policy debate that this work informs I’ll try to end on an optimistic note

Steering Technological Progress
Provocative and thought-provoking paper Premise: Planner’s preferences and HH endowments differ Redistribution through taxes and transfers is infeasible
Stylized model of ’ex-ante’ redistribution: subsidize tech. progress that favours some types of labor vs. others Authors acknowledge that steering progress is a difficult task As much about nudging innovators as informing policy

Comments on Steering Technological Progress
Mostly skirts the vexed question of factor supply elasticities Even in very stylized model, policy advice depends heavily on parameters: K and L gross complements? Subsidize capital tech. to help labor! K and L gross substitutes? Subsidize labor tech. to help labor! Example of ride-sharing is instructive: spare a thought for London’s cab drivers and their ’Knowledge’
Some really interesting directions for further research (and first-order concerns for policy makers): How to think about non-monetary benefits of work Interactions between technology and labor/firm market power

Digital Adoption, Automation, and Labor Markets in Developing Countries
Authors develop a rich theoretical model that can replicate these facts Key insight: cost of business creation AND digital tech adoption required for calibrated model to resemble data

Comments on Digital Adoption, Automation, and Labor Markets in Developing Countries
My take: data suggest that technological unemployment is second order concern (at least, starting from a low base) Adoption of digital technology is essential But can’t take for granted that benefits will be widely shared (Conjecture) In language of paper: if tech. adoption cost falls but business creation cost stays high, gains from tech. are concentrated Focus on implication for factor shares, wage premiums

Two approaches to mitigating distributive effects of tech. progress and adoption
Steer progress Nudges? Taxes and subsidies for R&D? Perhaps directing R&D not needed - at tech. adoption stage we have much better understanding of effects
Manage redistributive effects of technology Taxation & Redistribution Retraining & Upskilling Encourage technological diffusion (Finkelstein Shapiro and Mandelman (2020), Martinez (2019))
Some suggestive evidence that managing effects is not a lost cause
