Saturday Link Dump

Now that the summer's in full swing, it's time to empty out the old Bloglines account and do a link dump. I've been letting things build up, so this is a good opportunity to clean it out while SAS chews through the overly-large data set I'm torturing. So, without further ado, here are some links for your avoidance-behavior use:
Investing and Markets
CXO Advisory Group has posted some interesting pieces lately. In one, they report on a study by David Blitz and Pim van Vliet titled The Volatility Effect: Lower Risk without Lower Return. The study finds evidence that investors overpay for the most volatile stocks (i.e. they underperform on a risk-adjusted basis).

In another piece, they highlight work by Alex Edmans titled "Does the Stock Market Fully Value Intangibles? Employee Satisfaction and Equity Prices". Edmans finds that companies on Fortune magazine's annual list of the "100 Best Companies to Work for in America" outperform the market.

And finally, they discuss work by Ben Marshall, Rochester Cahan and Jared Cahan titled Does Intraday Technical Analysis in the U.S. Equity Market Have Value?. Their answer seems to be a pretty resounding "no" - they use some pretty rigorous statistically analysis (bootstrapping tests) to examine some 7,846 trading rules from five rule families (Filter, Moving Average, Support and Resistance, Channel Breakouts, and On-Balance Volume). They find that (after adjusting for what's called "data snooping bias") that none of the rules are profitable.

Hal Varian discusses how "A company's stock often does better than the investor who buys the stock".

Dealbreaker
discusses issues surrounding insider trading in the credit default swap market.

Private Equity
Bargeron, Schlingemann, Stulz, and Zutter (a group of college professors, not a law firm) recently conducted a study on the differences in gains to target shareholders for takeovers by private vs. publicly owned firms. They find that private acquirers leave less on the table (i.e. the targets get a lower announcement return when the acquirer is a private company). The answer seems to be that private firms' ownership structures lead to better decisions.

Academia
Craig Newmark links to a great paper on student evaluations
. It's specifically geared towards law school, but it's pretty generalizable, and has a lot of citations to prior work on factors that seem to drive evaluations.

Humor

How not to defend your dissertation (HT: Greg Mankiw)

We hold this to be self evident - the Trunk Monkey is hilarious.

Mixed bag
Nobel Laureate Vernon Smith talks about Asperger's Syndrome (HT: Craig Newmark).

If you have even seen blurry tattoos on people now you know why that
happened. Instead of searching on to find the fresh tattoo art, they simply settle on something they don't even 100% like. And although we may not be able to draw one ourselves, we know immediately when one doesn't look right.
ll find a whole bunch of high quality skull tattoos and all sorts of tribal and skull rose tattoo designs, you can also search tattoo parlours
and find trusted tattoo artists and studios in your local
area. It is also said, that much like a samurai, koi fish do not flinch
under the knife. Neither will certainly throat or
perhaps mind tattoos become permitted.
