What fraction of output was produced by enslaved people?

 

Paul Rhode has an important new paper in the January issue of Explorations in Economic History ("What fraction of antebellum US national product did the enslaved produce?." 2024. Explorations in Economic History 91). Rhode frames the argument against Ed Baptist’s claim that “almost half of the economic activity in the United States in 1836, derived directly or indirectly from cotton produced by the million-odd slaves…”, which has been not just repeated but exaggerated by others. It was easy to show that Baptist’s claim had no foundation in either theory or evidence and was purely a creation of Baptist’s imagination (see here), but the question of how large a fraction of output was produced by enslaved labor remained unanswered.

 

I have for years suggested that the place to begin an answer to this question is the labor supply. Begin with the percentage of the labor supply accounted for by enslaved people and then ask why the percentage of output would be either higher or lower than the percentage of labor (see for instance here in my thoughts on Stelzner and Beckert’s attempt to answer the question). I was too lazy to do the work, but fortunately for us Paul Rhode was not.

He estimates that the percentage of output was probably about the same as the percentage of the population, around 12 percent. He also does a series of robustness checks using alternative assumptions that raise or lower the estimate a little bit. As with all such estimates people will be able to quibble, but I think he makes a pretty strong case that it is difficult to produce an estimate that is much larger than the percentage of the population.

Rhode’s conclusion is not just important because he debunks Baptist. The flaws in Baptist’s work were so obvious that only people so enamored with his conclusions that they were willing to completely disregard all evidence continued to support his work. Rhode’s estimate is important because, like recent work by economists Hornbeck and Logan and the economic historian Joe Francis, it lays waste to a tradition rooted in the work of Fogel and Engerman. In Fogel and Engerman, slavery, although morally repugnant, was not just profitable it was efficient and highly productive. Later economists, including Engerman and Sokolof, would argue that despite its productivity slavery had negative long run consequences (see here for instance). But this recent work says that slavery did not just have negative long -term consequences, it was a massively inefficient misallocation of resources while it was taking place. Rhode’s conclusion that the fraction of output produced by enslaved labor was about the same as the fraction of the population accounted for by enslaved people means that the fraction was much less than the percentage of the labor force accounted for by enslaved people, about 22 percent in 1860.

Emancipation and Aggregate Economic Gains

 


 I recently listened to Rick Hornbeck on the Chicago Booth Review Podcast in the episode

An Economist Debunks Gone With the Wind


Its kind of  a silly name for the episode, but Hornbeck does a great job of describing important research by himself and and Trevon Logan. The paper calls for a significant reconceptualization of the economics of slavery. Hornbeck and Logan present slavery as a giant externality in which the labor of enslaved people was dramatically misallocated because slave holders did not have to take into consideration the full cost of their decisions. Consequently, although studies of emancipation have traditionally focused on the negative effect on production in the South, Hornbeck and Logan portray it as the biggest increase in productivity in American economic history.

Word on Fire/ Pants on Fire

 

I got an email notification last week for a new episode of Bishop Barron’s Word on Fire podcast  asking  Is There a Catholic Antidote to the Crisis in Higher Education

“According to Fortune magazine, overall undergraduate enrollment experienced the steepest rate of decline on record from 2019 to 2022, and it has only worsened since then.

There are several explanations, but one cause is entirely self-imposed: most universities and colleges have now replaced education with ideology, subverting the search for truth with political indoctrination.

In this episode of The Word on Fire Show, Bishop Barron and Matthew Petrusek, Senior Director of the Word on Fire Institute, discuss the ideological takeover of higher education and how the Catholic conception of the university can help provide an antidote.”

I’m afraid that before providing an antidote they should put some more work into their diagnosis. The episode does not provide any evidence that “most universities and colleges have now replaced education with ideology, subverting the truth with political indoctrination.” 

What it does provide are some references to the recent congressional testimony of some Ivy League presidents and some vague allusions to wokeness. Given the argument that students are not attending college because faculty are pressing a certain ideology and the Bishop’s example of the prevalence of this ideolog at Ivy League schools they must be at the forefront of the decline in enrollment. Anyone who knows anything about higher education knows that nothing is further from the truth. Ivy League schools are seeing record numbers of applications, leading to record low acceptance rates. They are doing just fine.

The schools that are seeing declining enrollments are less prestigious schools, especially smaller regional schools. The students who aren’t going don't express concerns about ideology; they are concerned about stress and mental health, the rate of return on their investment (which evidence still indicates is high), and their ability to pay. See, for instance, Exploring the Exodus from Higher Education

People will always be able to find anecdotes about some college course that they don’t like or some statement by an administrator that sounds preposterous, but as someone who has taught in colleges for more than 30 years, I just don’t see the world that Bishop Barron and other purveyors of the wokeness boogeyman want people to believe in. The most popular major in the United States is business, accounting for around 1 in 5 undergrads. Some of the other top majors are engineering, computer science, and nursing.  Are we seriously to believe that these schools are not in fact preparing people to be managers, accountants, engineers, computer programmers, data scientists, nurses, teachers, etc. but are instead just indoctrinating them in a political ideology?

 

If Bishop Barron really wants to play a positive role in higher education he should try to do better than this.

Planet Money on the political economy of rum in the U.S.

 

Planet Money has a nice story about rum production (The billion dollar war behind U.S. rum) in Puerto Rico and the Virgin Islands, particularly the consequences of Virgin Islands deal to lure Captain Morgan away from Puerto Rico.

It should be of interest to anyone paying attention to Youngkin’s attempts to lure the Capitals and Wizards away from D.C.

It is also a nice example of a real world prisoners dilemma type game.

What is Capital? Part 1: Bank Capital

 

This is from The New York Times article Why Big Banks (and Some Odd Allies) Oppose a Plan to Protect Banks:

“Regulators are calling for an increase in the amount of capital — cash-like assets — that banks have to hold to tide them over in an emergency to avoid needing a taxpayer-funded bailout like the one in the 2008 financial crisis.

 

No! No! No! No! No!

Bank capital is not “cash like assets.” Those are reserves. Reserves are money that banks keep either as cash or as deposits with other banks. They are cash like assets. And there are reserve requirements regarding the percentage of deposits that have to be kept as cash like assets, but those are not capital requirements.

A bank's capital is just the difference between the value of the bank’s assets and its liabilities. In other words, it is the equity the owners (shareholders) have in the bank. Capital requirements regulate the size of the capital. The most basic capital requirement is a leverage ratio, requiring that capital be equal to a certain percentage of assets.

Capital requirements are intended to deal with the threat of insolvency. A bank becomes insolvent when the value of its assets falls below the value of its liabilities, primarily the money it owes to depositors.

Why would the value of assets fall? The investments banks make are risky. The prices of securities that they buy, stocks or bonds, can go up, but they can also go down. If the bank owns stocks and bonds and the prices of those securities fall, the value of the bank’s assets falls. Part of the problem faced by Silicon Valley Bank was that it purchased a lot of long term bonds before interest rates started to increase, and as interest rates rose the price of those bonds fell. The loans banks make can also decrease in value. If the bank loans money to a person or a business and they do not repay the loan, the value of that asset (the loan) falls. In U.S. history, bank runs, (people racing to the bank to withdraw their money) tended to occur during economic downturns when falling security prices and failing businesses meant that the value of bank assets were declining. Under these circumstances people had greater reason to fear that some banks might become insolvent and not be able to repay their deposits. Capital helps protect against insolvency and banking crises.

Capital helps protect against insolvency by providing a cushion when asset prices fall. Assume you have $100,000 in assets, $80,000 in deposits and $20,000 capital, if the value of your assets falls by $15,000, you still have more than enough to cover all of your deposits. On the other hand, if you had $100,000 in assets, $90,000 in deposits and $10,000 capital, a decrease in value of $15,000 would leave the bank insolvent. In addition, it can be argued that banks have less incentive to take excessive risk when they have more of their own money at stake. They have more skin in the game.

Financial institutions, including banks, generally recognize the benefits of capital. I have written a lot about the history of New York City trust companies and one of the things they were most likely to mention in advertisements was the size of their capital. They called it capital and surplus, but it meant what we mean when we talk about a bank’s capital today. They used their capital to signal their strength and stability.

            There is, however, also a cost of higher capital: a lower rate of return. A higher capital requirement means that you have to rely more on bank owner’s money and less on borrowed funds (deposits). The extent to which you rely upon borrowed funds is called leverage. To see how leverage affects return on investment consider this example. You know of an investment that will return 10%. You have $100 you can invest. You do so and end up with $110, earning that 10% rate of return. Now imagine you can borrow another $100 from someone else at 5%. You now use their $100 and your investment of $100 for a total of $200. You get back the $200 plus 10% of 200, $220. You have to give the person you borrowed from $105, leaving you with $115. Your $100 investment now earned $15 for a 15% rate of return. That is the power of leverage. Of course if that investment you made doesn’t pay off we are back to worrying about insolvency. You still owe $105.

            So what is the story in the New York Times actually about. Its really about how complicated capital requirements can get. Toward the end of the article they point out that some suggested regulations could decrease certain kinds of lending. This is because capital requirements are no longer set based upon a simple leverage ratio that applies to everyone. Modern capital requirements recognize that not all investments are equal. Some are riskier than others. So regulations assign different risk assessments to different assets and then provide a risk weighted capital requirement. More risky assets, more capital. The argument of opponents of increased capital requirements is that these risk assessments could discourage banks from making some kinds of loans that we actually want to promote. In other words, it could get harder to get a mortgage to buy a home or take out a loan to start a business.

            I’m not going to try to answer which side is right. This isn’t about whether banks should have capital requirements, its about how much capital is enough. That is a hard question. My objective here has been to clarify what people are talking about when they are discussing banks and refer to capital. The post is titled part 1 because this is not the only meaning of capital. In other contexts, the meaning of capital is very different, and I plan to discuss that in the future. Who knows, eventually I might even take on the meaning of capitalism.
