There are two kinds of episodes here:
1. For the most part, episodes June-August are weekly, short (<20 mins), and address a few topics.
2. Episodes September-May are longer (1 hour), and monthly, with an interview with a guest.

The Answer Is Transaction Costs
Exchange Takes "Place," and the Strange Case of Lettuce
Why would sellers go to a "place" where many others are also selling the same product? Wouldn't it better to go someplace off by yourself, so you can get the monopoly price? Well, the answer is that transactions"take place," meaning they require a context. Amazingly, it's better to go where all the other sellers are going, because of the problems of triangulation, transfer, and trust. The Sears catalog was a "virtual" (paper) place, and Amazon is another "virtual" (online) place. But the answer to why we do that is "transaction costs."
But then I go back in time to my own introduction to the notion of transaction costs, in a class taught by the remarkable economist Yoran Barzel. The puzzle is so simple that it seems dumb: why do we measure lettuce by the head, meat by the pound, and diamonds by the caret?

Plus, the TWEJ!
And our first letter, as a homework assignment.
Are congestion taxes an effective way to overcome transactions costs pertaining to efficient use of roads? Probably not the best. There is no externality with congestion, because everyone stuck in traffic has moved to the harm. Those who could be held liable for causing congestion are not those who pay for a variable toll, but those who come later.
We'll talk about this in Week 3!
