This document provides clarifications and guidance for researchers seeking to replicate the analyses in our paper. This is important as we identified some items in the published text and the code where additional clarity would be helpful. While none of these affect our substantive conclusions,...

Electric vehicles (EVs) are crucial for cutting transportation emissions, yet the policy drivers of EV innovation remain underexplored. This study analyzes firm-level panel data on EV and battery patents, covering more than 4,000 firms across 19 countries from 2010 to 2021, to assess how these...

How are preferences for innovation formed, and what determines the long-run direction of technological change? This paper shows that early-life exposure to environmental accidents can durably reorient inventive effort decades later, even in the absence of targeted policy. I study radioactive...

We investigate the causal relationship between inventor migration and regional innovation in the context of the large-scale migration shock from East to West Germany between World War II and the construction of the Berlin Wall in 1961. Leveraging a newly constructed, century-spanning dataset on...

The share of female inventors remains significantly lower than that of men in both developed and developing countries. This paper studies gender bias in patenting activity, using a unique dataset that matches Italian administrative employer-employee records both to patent data from the European...

This study investigates the relationship between Artificial Intelligence (AI) and innovation inputs in Spanish manufacturing firms. While AI is increasingly recognized as a driver of productivity and economic growth, its role in shaping firms’ innovation strategies remains underexplored. Using...

This paper presents direct evidence on how firms' innovation is affected by access to knowledgeable labor through co-worker network connections. We use a unique dataset that matches patent data to administrative employer-employee records from "Third Italy"- a region with many successful...

Large firms generate most American inventions. We know that cities are host to organizations of varying size and prevalence, but are these conditions important to urban system dynamics? This article presents volatility in patenting as a novel instrument for distinguishing between cities reliant...

We show that personal experiences affect high-stakes economic decisions among inventors. Using matched patent and survey data from French and German inventors linked to natural disaster records, we exploit exogenous variation in disaster exposure. Inventors personally affected by natural...

Organizations aim to overcome path dependency in technological capabilities by diversifying knowledge internally through interfirm and cross-functional innovation. This study investigates the impact of the obeya (big room) concept-a collaborative workspace where diverse disciplines converge in a...

Only a small fraction of inventors are women. Using Finnish administrative data linked to patent records, I show that educational and occupational sorting explain roughly 54% of the gender gap in patenting rates. The remaining 46% arises because women patent less than men within nearly all...

We show that firm and industry, rather than inventor and invention factors, explain more than half of the variation in inventor returns in administrative employer-inventor-patent-linked data from Germany. Between-firm variation in inventive rents is strongly associated with inventor mobility....

This paper studies how the speed-quality tradeoff in innovation interacts with firm dynamics, concentration, and economic growth. Empirically, we document long-run trends in the increasing speed of innovation alongside declining quality at large firms. Leveraging variation from an exogenous...

ANR Patentes is an Argentinean program that gives grants for patents applications to innovative firms, entrepreneurs and researchers. Throughout the period 2007-2017, 83 projects (out of 195) were funded. Based on secondary sources and a survey conducted to beneficiaries, this study reconstructs...

Purpose This paper aims to study the impact of CEOs' cultural background on corporate innovation. The paper constructs a measure of CEOs' cultural individualism based on their birthplaces and investigates its relationship with firms' patents and citations. The study aims to shed light on the...

This paper develops an endogenous growth model that incorporates a frictional inventor market and examines the allocation of inventors across firms, knowledge diffusion, and its impact on growth. In our model, inventors play dual roles: they engage in in-house R&D and transfer knowledge from...

We study the technology sovereignty of Europe, the US, China, Japan, and Korea. By examining citations from PCT patents filed from 2000-2020, we assess the bilateral and global influence of inventions. We highlight four insights. First, the US shows superior technology sovereignty through its...
