A model with proportional errors in variables arising naturally in microeconomics is considered. Unlike the classical additive errors case, all OLS parameter estimates exhibit attenuation bias that does not depend on the limiting distribution of the data. The distribution of OLS estimators is...

Risky production functions which are commonly in use are shown to be very restrictive. In particular, such functions cannot describe technologies where inputs marginally reduce risk. A simple production function which avoids these restrictions is posited and alternative estimation procedures are...
