Tyler Cowen notes his passing. One of his difficult books, The Escape from Hunger and Premature Death, had an enormous influence on my thinking. In fact, it was just one table, showing the long-term income elasticities of large categories of goods and services, that I have referred to many times. Indeed, The New Commanding Heights, the essay that Nick Schulz and I wrote, is hardly more than an extended riff on that table.
