This paper estimates a sequence of energy-saving technology choices by Dutch glasshouse firms. The model allows for time-constant, firm-specific effects and serial correlation of errors and it is estimated on panel data over the period 1991-1995. The unobserved error sequences are simulated in...

This paper applies a semi-parametric approach to estimating a generalised model of investments in heating installations. The results suggest that marginal costs of investments in heating installations increase quickly at small investment levels, whereas the increase slows down at higher...

World-wide, government institutions play an important role in the management of plant health. This paper develops a conceptual framework in which suppliers and demanders jointly determine the optimal level of plant health in a hypothetical market. Next this paper argues that this market falls...

The disciplinary nature of most existing farm models as well as the issue specific orientation of most of the studies in agricultural systems research are main reasons for the limited use and re-use of bio-economic modelling for the ex-ante integrated assessment of policy decisions. The...

This research proposes a parametric estimation of the structural dynamic efficiency measures proposed in 2009 by Silva and Oude Lansink. Overall, technical and allocative efficiency measurements are derived based on a directional distance function and the duality between this function and the...

The stochastic distance function model is extended to allow for the inefficiency component of the error term to be autocorrelated, as implied by a dynamic model of firm behavior. The autocorrelation parameter can then be interpreted as a measure of the persistence of inefficiency. The model is...
