lnx1 is the log of labour, lnx2 the log of capital, lnx3 the log of material costs, γ an estimate of the share of technical |
efficiency in total variance and μ the mean of the distribution of inefficiency effects.
Standard errors are given in parenthesis, *** indicates significance at the 1% level, ** indicates significance at the 5% level, *
indicates significance at the 10% level
*Restricted to Cobb-Douglas model due to violation of theoretical properties
