In the Journal of Agricultural and Applied Economics Volume 47 (Number 1), Equations 7 and 10 were published with errors. The corrected equations are reprinted below:
(7)
\begin{equation}
y_i (t|{\bm \Omega }_i ) = e^{ - k_i t} ( {y_{0i} - m_i (1 - e^{k_i t} )} ).\end{equation}
(10)
\begin{equation}
\quad \quad \hat \pi _{ip} (t) = p_{ip} e^{ - \widehat{k}_i t} ( {y_{0i} - \widehat{m}_i (1 - e^{\widehat{k}_i t} )} ) - w_i t - F_i,\end{equation}
