The intersection between tight labor markets, housing costs, and the opportunity cost of entrepreneurship: Free Exchange. The work by Fairlie and Chatterji that Ryan cites here is terrifically important and has not gotten nearly enough attention.
Why is carried interest taxed as it is? Observational Epidemiology.
What the studies say about private equity. Dealbook (via Marginal Revolution). Tyler sums it up: "'Some positives, lots of uncertainty' would be a good description of the available evidence."
Brad Feld on the intra-metropolitan geography of entrepreneurship. We probably need some new mapping tools. Feld Thoughts.
As an aside, I completely agree with Brad that "entrepreneurial density" is a good measure of a region's culture of entrepreneurship, but I don't know if we can yet measure it precisely. For one thing, we need to agree on a common definition of entrepreneurship. Then we need to figure out how to count it--government data are not entirely helpful here. Then we need to figure out what it means. One of our research assistants has been looking over Business Dynamics Statistics data on employment in young firms as a share of total employment in each state over the past three decades. We will post some charts and findings soon, but as the data relate, so far, to existing literature, I am reminded of The Princess Bride:
Vizzini: "He didn't fall? INCONCEIVABLE!"
Inigo Montoya: "You keep using that word. I do not think it means what you think it means."
(h/t to PK for the reminder of this pricelessly fungible line the other day)
