Fostering Innovation: Addressing Underrepresentation, Policy Levers, and Market Dynamics

This podcast episode, featuring John van Reenen, Gordon Bernards Professor at MIT, delves into the multifaceted challenges and policy solutions for stimulating innovation, particularly focusing on the underrepresentation of certain groups in the inventor pool. Van Reenen highlights that disparities in invention are not primarily due to differences in preferences or abilities, but rather a lack of opportunities and exposure, coining this the "lost Einstein or lost Marie Curie" effect. He presents compelling data, noting that children from the top 1% income bracket are ten times more likely to become inventors than those from the bottom 50%, underscoring the profound impact of socioeconomic background on innovative potential. The discussion emphasizes that addressing these systemic barriers could significantly boost national innovation capacity.

The episode distinguishes between various policy approaches to foster innovation, categorizing them into supply-side and demand-side interventions. Supply-side policies aim to increase the quantity and quality of human capital, such as encouraging immigration of skilled inventors or investing in homegrown talent through education and mentorship. Demand-side policies, conversely, focus on subsidizing innovation investments like research and development (R&D) through tax credits or direct grants. Van Reenen discusses the trade-offs, noting that R&D tax credits are attractive for their market-driven approach, avoiding the need to "pick winners," while direct subsidies, though more bureaucratic and prone to capture, can be targeted towards areas with high social benefits, such as basic research in health or climate change, where spillover effects are substantial. He also stresses the often-underestimated role of competition, trade openness, and immigration in driving innovation.

Practical insights revolve around concrete strategies to unlock innovative potential. To combat underrepresentation, van Reenen advocates for providing role models, mentors, improving schools, and implementing venture education programs for talented children from disadvantaged backgrounds, suggesting such efforts could quadruple U.S. innovation. For broader economic policy, he argues for the state's essential role in addressing market failures inherent in innovation, such as the public goods problem and uncertainty, but cautions against unintended consequences. The state must balance growth with inclusive outcomes, ensuring that benefits are not concentrated among a small elite, and considering criteria like inequality and social inclusion in its interventions.

Finally, the episode explores broader implications concerning market structure and competition. Van Reenen observes a significant increase in market concentration across many U.S. industries over the last 40 years, attributing it to multiple factors: increased competition pushing out less productive firms, network effects in high-tech industries (e.g., Google), the "Walmart effect" of large investments in intangible capital (like software logistics), and, most worryingly, a reduction in competition due to lax antitrust enforcement, anticompetitive mergers, and lobbying that creates barriers to entry. He suggests that modernizing antitrust law is crucial to address these issues, particularly in sectors like healthcare, airlines, and telecoms, to prevent further decline in innovation stemming from weakened market rivalry.

"if you look at where inventors come from there's lots of groups who've seen to be really highly underrepresented in the inventor pool"

"kids born into the top 1% of the income distribution they're ten times more likely to grow up to be an inventor than kids born into the bottom 50% of the income distribution"

"what does explain a lot more is the opportunities and the exposure many of these kids have had at young age to innovation"

"we call this like a lost Einstein or the lost Marie Curie type of effect"

"economists call that a public goods problem but you know the benefits of spillover much more widely"

"for the basic research maybe a more directed approach is appropriate where we have clear criteria about what we really want"

"if all you do is increase the demand for the given number of scientists and you can't increase the number of scientists people like me that our wages might cut off but we don't get much for innovation"

"one of the strongest ways of actually trying to get some these underrepresented groups into being inventors is to give them role models mentors the possibility the possibility of becoming inventor also to change the neighborhoods and the schools where they grow up"

"if you could do something to change that you could quadruple the amounts of innovation there is in the u.s."

"the fact they have a good search algorithm means all people use it which means they get more data which means they improve the search algorithm and this network effect enables firms to dominate their industries"

"this growth of this importance of intangible capital has given advantages to these already large firms and the superstar firms and made them even bigger"

"maybe what's happened is that the antitrust and forces of north enforce antitrust properly they've allowed to many anticompetitive mergers to take place"
