We construct a model of creative destruction with endogenous firm dynamics. We integrate the theory into a general equilibrium multi-country model of technological convergence where countries interact via international spillovers. We derive implications for both firm dynamics and aggregate...

Why don't poor countries adopt more productive technologies? Is there a role for policies that coordinate technology adoption? To answer these questions, we develop a quantitative model that features complementarity in firms' technology adoption decisions: The gains from adoption are larger when...

This paper proposes a new framework for studying the interplay between culture and institutions. We follow the recent sociology literature and interpret culture as a \repertoire", which allows rich cultural responses to changes in the environment and shifts in political power. Specifically, we...

Are the well-known facts about urbanization in the United States also true for the developing world? We compare American metropolitan areas with comparable geographic units in Brazil, China and India. Both Gibrat's Law and Zipf's Law seem to hold as well in Brazil as in the U.S., but China and...

Popular literature suggests a rapid narrowing of the technology gap between China and the U.S. based on large percentage increases in Chinese patent applications, and equally large increases in college registrants and completed PhDs (especially in sciences) in China in recent years. Little...

Consumer choices are increasingly mediated by algorithms, which use data on those past choices to infer consumer preferences and then curate future choice sets. Behavioral economics suggests one reason these algorithms so often fail: choices can systematically deviate from preferences. For...

We conduct an interactive online experiment framed as an employment contract between employer and worker. Subjects from the US, India, and Africa are matched in pairs within and, in some cases, across countries. Employers make a one-period offer to a worker who can either decline or choose a...

Governments often prohibit resale of the benefits-in-kind provided by antipoverty programs. Yet the personal gains from those benefits are likely to vary and to be known privately, so there can be gains to poor people from trading their assignments. We know very little about those gains. To help...

We analyze the history of Japanese foreign exchange interventions from 1971 to 2018. First, we provide the best proxy for monthly interventions for the period from 1971 to 1990, when the intervention timings and amounts were not officially disclosed. The accuracy of the proxy is tested for the...

How should recipients of publicly-provided goods and services prove their identity in order to access these benefits? The core design challenge is managing the tradeoff between Type-II errors of inclusion (including corruption) against Type-I errors of exclusion whereby legitimate beneficiaries...
