I found myself frustrated by her conversation with Russ Roberts. She repeatedly points out that government has funded successful innovations. The implication, in her view, is that we should pay higher taxes in order to fund more innovation.
But the question is whether the government or the private sector is structurally more suited to spending money on innovation. It seems to me that Russ could not get Ms. Mazzucato to discuss the issue at that level. Trading anecdotes back and forth about particular private-sector and public-sector successes and failures is not constructive. I gave up listening well before the podcast ended.
I like to break down innovation into experimentation, evaluation, and evolution. I think that government has a disadvantage at all three.
Any one organization is limited in the number of experiments on which it can focus. When the government was focused on landing on the moon, it succeeded. But it is hard for any one organization, not just government, to focus on a lot of experiments at once.
When it comes to evaluating experiments, everybody is overly optimistic about their own projects. But in the private sector, the subjective evaluation of the project champions is subordinate to the third-party evaluation of consumers. In the public sector, the legislators and bureaucrats who champion a project also are doing the evaluation.
Finally, when it comes to evolution, government has no natural mechanism to shut down unworthy projects. When a private-sector project is not producing value, it loses money and gets terminated.
Twenty years ago, I wrote an essay in which I explained why, contrary to what some pundits were arguing, middle managers should not be encouraged to take more risks inside corporations. In essence, I made a “skin in the game” argument. That argument applies very strongly to the case of government-funded risk-taking, in which the cost of failure is not borne by the decision-makers.
