AN EVALUATION OF INTEGRATED PEST MANAGEMENT WITH HETEROGENEOUS PARTICIPATION 31
Wetzstein, Michael E.; Musser, Wesley N.; Linder, David K.; Douce, G. Keith.
Principal component analysis in employed to develop indices that distinguish between participants and nonparticipants in Integrated Pest Management (IPM) programs. Results of incorporating these indices into yield, net return, and production cost functions for cotton producers indicate that both yield and costs increase as the degree of producer participation in IPM increases. Although these results are inconsistent with previous research, they are consistent with the theoretical relationship between IPM and conventional input usage.

EVALUATION OF VARIOUS PEST-MANAGEMENT CHARACTERISTICS 31
Smith, G. Scott; Wetzstein, Michael E.; Douce, G. Keith.
Considering pest management in terms of a set of technology characteristics allows an investigation of various pest-management characteristics and how they relate to a total pest-management package. Employing restricted and unrestricted least squares in this investigation indicates the unique impact individual pest-management characteristics exert on net returns. A Stein-rule estimator is also employed in assessing this impact.
