Space Debris, Governance, and the Economics of Space with Alex Salter

What follows is an edited transcript of my interview with Alex Salter about the economics of space. The first half deals primarily with the issue of space debris, while the second half deals with the possibility of private governance in space. There’s something in this episode for everyone to enjoy, so I hope you’ll listen, read, and share it with your friends.


Petersen: My guest today is Alex Salter of Texas Tech University. Alex, welcome to Economics Detective Radio.

Salter: Thanks very much for having me.

Petersen: Our topic today is the economics of space. Alex has written two papers on the subject. The first is entitled, “Space Debris: A Law and Economics Analysis of the Orbital Commons.” The second is, “Ordering the Cosmos: Private Law and Celestial Property Rights.”

So Alex, let’s start by talking about space debris. What is it and why does it matter?

Salter: So space debris is basically junk in space that no longer serves any useful purpose. So as you can imagine, since the first piece of space debris launched up in 1957—which was the rocket body from Sputnik I—a lot of orbits around the Earth, especially low Earth orbit, have become kind of cluttered with space junk. And the reason it gets cluttered is because no one has an incentive to clean it up. (more…)

Re-thinking the U-Curve of Inequality with Vincent Geloso

What follows is an edited transcript of my conversation with Vincent Geloso.


Petersen: My guest today is Vincent Geloso of the Free Market Institute at Texas Tech University. Vincent, welcome to Economics Detective Radio.

Geloso: It’s a pleasure to be here.

Petersen: So the paper we’ll be discussing today is titled “A U-curve of Inequality? Measuring Inequality in the Interwar Period” which Vincent has co-authored with John Moore and Phillips Schlosser. The paper casts doubt on the claim from, most notably, Thomas Piketty and others that inequality fell from the 1920s to the 1960s and rose thereafter. So, Vincent let’s start by discussing the inequality literature prior to this paper. What is this U-curve and where did it come from?

Geloso: The U-curve is probably the most important stylized fact we have now in the debate over inequality and the idea is that, if you look at the twentieth century, there’s a high point of inequality in the 1910s, 1920s and then from the 1930s onwards up to 1970s, it falls dramatically to very low levels and re-increases thereafter, returning to 1920s-like levels of inequality. So the U-curve is the story of inequality in the twentieth century. It’s mostly a U.S. story because for other countries it looks less like the U-curve than an inverted J. So it’s higher in the 1920s, it still falls like in the U.S. but really increases much more modestly than the United States in places like Sweden, or France, or Canada. But the general story is that there was a high level of inequality at the beginning of the century well up to the mid-second-half of the twentieth century and it re-increased in the latter years and then we have been on a surge since then.
