Tycho Brahe was a significant figure in my family. Why? Because my father’s parents were from Denmark, and Tycho Brahe was Danish. Danes were thus important in the Benzon household, as was Danish pastry (wienerbrød, Vienna bread), the real stuff with cardamom seeds, not the fluff you get in diners. And then there is rabarbergrød, a cloudy translucent rhubarb pudding laced with slithers of almonds. Not to mention Danish layer cake, five thin cookie-like layers alternating with custard and currant jelly topped with a lemon-juice & powdered sugar icing, once a year on my father’s birthday. But I digress.
We were told about Leif Erikson, who made landfall in the Americas half a millennium before the Italian. About King Christian X, known for his defiance of Hitler, which – wouldn’t you know? – became embroidered with legend.

Whoops! I digress.
This essay isn’t about desserts, kings, or even comedians. It’s about a living intellectual, the economist Tyler Cowen. I won’t bother with boilerplate basics, you can find that in Wikipedia. As for his similarity with that long-deceased 16th century Danish astronomer, Tycho Brahe, we need to have some appreciation for what Cowen has done before stacking him up against the dead Dane.
First up, Cowen’s blog. Then we blitz through a list of 59 people he’s interviewed (out of 279 so far), then on to philanthropy, after which we slow way down to look at his current monograph, The Marginal Revolution: Rise and Decline, and the Pending AI Revolution. When we’ve gone through that we’ll understand the comparison with Tycho Brahe. Read more »

A moat is what protects a business from competition. The term comes from Warren Buffett’s image of a castle surrounded by water. The castle is the business; the moat is whatever prevents rivals from storming the walls. A moat might be a famous brand, a patent, a network effect, control over scarce resources, high switching costs for consumers, or a regulatory barrier that makes it difficult for competitors to enter the market. The deeper the moat, the easier it is for a firm to charge high prices, preserve margins, and survive imitation.
