What's the difference between invention and innovation? Could it be that innovation--the process of making a breakthrough invention available, affordable, and reliable--is actually the hard part? In this week's EconTalk episode, author Matt Ridley talks about his book How Innovation Works with EconTalk host Russ Roberts. Ridley argues that we give too much credit to inventors and not enough to innovators--those who refine and improve an invention to make it valuable to users. Along the way, he emphasizes the power of trial and error and the importance of permissionless innovation.

Franklin Zimring's 2017 book, When Police Kill, starts with an alarming statistic: Roughly 1,000 Americans die each year at the hands of police. Zimring, criminologist and law professor at the University of California at Berkeley, talks about his book with EconTalk host Russ Roberts. Zimring argues that better policing practices can reduce the number of citizens killed by the police. He also discusses the barriers that stand in the way of more effective and safer policing.

In this c750th (!) episode, Duke University's Michael Munger talks with EconTalk host Russ Roberts about whether the pandemic might create an opportunity for colleges and universities to experiment and innovate. Munger is Professor of Political Science, Economics and Public Policy at Duke. He believes "top" schools can emerge from the current period of uncertainty to thrive in the long run. The path for "second-tier" institutions could be more difficult. They will still face the challenges that existed before the pandemic: competition from online classes and a shrinking pool of new applicants ready to pay high tuition bills.

Journalist and author Ben Cohen talks about his book, The Hot Hand, with EconTalk host Russ Roberts. At times in sports and elsewhere in life, a person seems to be "on fire," playing at an unusually high level. Is this real or an illusion? Cohen takes the listener through the scientific literature on this question and spreads a very wide net to look at the phenomenon of being in the zone outside of sports. Topics include Shakespeare, investing, Stephen Curry, and asylum judges.

Physician and author Vivian Lee talks about her book The Long Fix with EconTalk host Russ Roberts. Lee argues that we can transform health care in the United States, though it may take a while. She argues that the current fee-for-service system incentivizes doctors to provide services rather than keep patients healthy and that these are not the same thing. Topics explored include innovations in Medicare and in technology that might change treatment incentives as well as the weird world of health care pricing.
