“A peculiar psychological disorder known as ‘physics envy'...We would love to have three laws that explain 99% of economic behaviour; instead, we have about 99 laws that explain maybe 3% of economic behaviour. Nevertheless, we like to talk as if we are dealing with physical phenomena.”
Andrew Lo, MIT, financial economist
* Stochastic process xt is considered a fair game if Et[xt+1]=0. In the case here, Et[xt+1]=Et[rt+1]-rt.
* Several recent interesting models of bubbles have all agents rational, but that this not common knowledge, with the rest of the framework essentially classical. See Abreu, D. and Brunnermeier, M. K. 2003.

“The bottom line...is that theory by itself does not inevitably lead a researcher to a presumption of market efficiency. At the very least, theory leaves a researcher with an open mine on the crucial issues....market efficiency only emerges as an extreme special case, unlikely to hold under plausible assumptions.”
Schleifer, A., 2000, p16.
* Or, since the alternative to owning is renting, the opportunity cost of owning (via payment of interest) is compared to the alternative of renting. So if the typical rent is falling as house prices are rising, then buying housing and renting it to yourself is getting more expensive than letting someone else buy it and you rent it from them. There are, however, some weighty problems in dealing with the tax advantage of housing and the different tax treatments of renting.

“Without such a nonlinearity or dummies for the spikes in the data, the equation standard error more than doubles”. They find that by taking the frenzy component and downside risk term out, the shift in the income growth component and the 1980s real interest rate effect become “quite insignificant”. In conclusion they comment:“These results suggest that the omission of a non-linear ‘frenzy’ effect is a major specification error. The omission worsens the fit and fails to support the predictions of economic theory regarding the consequences of financial liberalisation, which are supported by a better specified model including a ‘frenzy’ effect.”
