Let denote the Gauss-Newton estimator of the parameter ([alpha],[beta]) in the autoregression model Zij=[alpha]Zi-1,j+[beta]Zi,j-1-[alpha][beta]Zi-1,j-1+[var epsilon]ij. It is shown in an earlier paper that when converges in distribution to a bivariate normal random vector. A two-parameter...

A strongly consistent sequence of estimators of the variance of the disturbance term in a nonlinear regression model is given. This improves earlier results based on either equicontinuity or uniform convergence arguments.

The objective of this study is to examine the market valuation of environmental capital expenditure investment related to pollution abatement in the pulp and paper industry. The total environmental capital expenditure of $8.7 billion by our sample firms during 1989-2000 supports the focus on...

This paper is concerned with the decision problem faced by a firm which produces a non-storable commodity and has to spend large amounts of capital on a specialized factor that could remain idle part of the time because of fluctuations in production. The optimum decision rule is derived under...
