We’ve heard of Johannes Haushofer’s iconic “CV of failures“, but Professor Haushofer’s anti-CV has got nothing on Caitlin Kirby’s skirt consisting of academic rejection letters (pictured below). Kirby, a doctoral candidate at Michigan State University, defended her dissertation while wearing a skirt made of 17 rejection letters–rejections from grants, scholarly journals, and academic conferences–that she had received during the course of her graduate studies:

To make this unconventional skirt, Kirby printed out 17 rejection letters and folded each one into a fan, connecting them in rows until they resembled a skirt. According to this report, Kirby still had many rejection letters left over. Good for her! Hat tip: @pickover.

By now, you have probably heard of Greta Thunberg, the world-famous Swedish teenage climate-change activist who has urged immediate action to address the risks posed by man-made climate change. That’s putting it mildly; in the words of Ms Thunberg, “People are suffering. People are dying. Entire ecosystems are collapsing. We are in the beginning of a mass extinction. And all you can talk about is money and fairytales of eternal economic growth. How dare you!” Although Ms Thunberg is no doubt a very eloquent speaker, her stern and strident call for action suffers from a fundamental flaw: one must also consider the benefits–not just the costs–of continued economic growth. Climate activists like Ms Thunberg do a great job of pointing out the environment costs of economic growth, but we must not blind ourselves to the benefits of growth nor ignore the costs of economic decline. A further irony is that curtailing the world’s continued economic growth will make it less likely that we will find a solution to climate change! To sum up, fanaticism in defense of the environment is a vice.

Check out Kay Hymowitz’s excellent review of Daniel Markovits’ new book (pictured below), which is titled The Meritocracy Trap (Penguin, 2019). Here is one revealing excerpt from her review of Markovits’s book: “As economist (yes, Harvard-educated) Tyler Cowen has quipped: ‘The best critiques of the meritocracy have come from those with extreme merit.’ I’ll come back to this puzzle later, for it’s one that Markovits’s book, like others in the genre, doesn’t fully explore.”

In anticipation of today’s announcement of “The Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel,” check out this fascinating survey essay by Allen R. Sanderson and John J. Siegfried titled “The Nobel Prize in Economics Turns 50,” which was published in American Economist, Vol. 64, No. 2 (2019), pp. 167–182, and is available here. In the words of Sanderson and Siegfried, “as a well-known quip has it, economics is the only field in which two people can share a Nobel Prize for saying opposing things,” such as the 1972 econ Nobel awarded to Gunnar Myrdal and F. A. Hayek or the 2013 prize awarded to Eugene Fama and Robert Shiller. Also, check out this critique of the other Nobel prizes. In any case, no person born in Africa, Latin America, or Oceania has ever won a Nobel prize in economics. Hat tip: Timothy Taylor.

Tampa, Florida is a case study of the decline of streetcars and the corresponding rise of massive roadways in North American cities. In 1920, for example, Tampa had an elaborate streetcar system consisting of 13 lines owned and operated by the Tampa Electric Co. Today, Tampa is a veritable “hellscape of highways,” a traffic-congested city bisected by three intrusive interstate expressways (4, 75, and 275) as well as an elevated toll road, while only one streetcar line is left up and running. To visualize this radical difference, compare the top map of modern-day Tampa with the bottom map of Tampa circa 1920. (Hat tip: Jake Berman, u/fiftythreestudio.)

We interrupt our series of blog posts on Ramos v. Louisiana and the Insular Cases to share this beautiful picture of Australian Gouldian finch birds (hat tip: @pickover). According to Dr Leah Williams and Dr Claudia Mettke-Hofmann, these finches adjust their behavior according to the personality of their partners. Here is a summary of their research; here is their full report.

Balzac v. Porto Rico was not the first time (cf. Dred Scott), nor would it be the last (cf. Roe v. Wade), that a decision repugnant to the Constitution would be made–not by Congress nor by the President–but by the Supreme Court of the United States (SCOTUS). But let’s focus on the Balzac case here: why did SCOTUS decide to deny Jesus Maria Balzac his constitutional right to a jury trial in this historic case? The most charitable reason is legal culture. After all, juries are a “common law” institution originating in medieval England centuries ago, while such newly-acquired U.S. territories like Puerto Rico and the Philippines, former colonies of Spain, followed the Roman or “civil law” tradition of continental Europe. On this view, because Puerto Rico’s legal culture was so different than that of other U.S. territories (where the right to a jury trial did apply), Puerto Rico’s insular government should not be compelled as a matter of constitutional law to adopt a jury system. Or, in the cynical words Chief Justice William Howard Taft, who wrote the Court’s unanimous opinion in this case: Continue reading →

Balzac v. Porto Rico, decided in 1922, was the last of the Insular Cases. First off, notice how the island is referred to as “Porto Rico” in the name of this case. This is because the United States had changed the island’s official name to Porto Rico for some reason when the U.S. acquired her in 1898 at the conclusion of the Spanish-Cuban-American War. The defendant in this case was Jesús Maria Balzac y Balzac, the editor of a newspaper called El Baluarte. The Government of Puerto Rico had charged Mr Balzac of criminal libel after he had written and published an article criticizing the governor of island. Mr Balzac then demanded a jury trial, arguing that the provisions of the U.S. Constitution, including the Sixth Amendment right to a jury trial, applied to Puerto Rico. After all, Puerto Rico was a U.S. territory, and the Congress had recently granted U.S. citizenship to all persons born in Puerto Rico under the Jones Act of 1917, so how could the insular government deny her U.S. citizens the right to a jury trial or any other constitutional right, for that matter? Mr Balzac’s appealed his case all the way up to the Supreme Court of the United States (SCOTUS), but as we shall see in my next few posts, the justices of that august forum–including such supposed champions of civil liberties as Louis Brandeis and Oliver Wendell Holmes–would find a way of denying Mr Balzac of his most basic constitutional rights.
