views on lecturer Gordon Klein

is there any crowd wisdom?

the best (and easy) estimator of market-beta?

did low market-beta stocks hedge well in market crashes?

did high-beta stocks even outperform low-beta stocks in the long-run?

did real-estate really influence corporate cap-ex?

did companies try to maintain stable leverage ratios?

do many possible action choices render cascades unimportant?

did stocks outperform bonds because they were riskier or longer-term?

could you predict stock returns with dividend-yields (etc)?

can you measure disaster risk in-time? Can it explain the equity premium?

is the real interest rate after-tax unusually low?

is evidence of portfolio reversals evidence of stock reversals?

has in/ex-clusion from the S&P500 changed over the decades?

does your paper or the draw of the referee matter more?
