Management Type Environmental Policy Instruments – An Empirical Investigation

The overall aim of this study is to empirically investigate the cost structure of a management agreement type agri-environmental instrument and to identify factors for cost variation over space and time. We control for the actual level of compliance by using compliance weighted average scheme cost ratios. Beside technological and economic performance measures, we also incorporate risk proxies. In addition, we consider unobservedheterogeneity or path dependency with respect to unknown administrative, spatial and farm specific factors. Hence, we try to disentangle random and fixed scheme cost effects by applying a bootstrapped mixed-effects regression approach using the empirical case of the Environmental Stewardship Scheme in the UK. Regionaland sectoral variation in the scheme uptake and the cost of compliance for the participating farms lead to significant cost effects reflecting heterogeneity with respect to management skills and attitudes, production focus, location, technologies, economic performance and risk.
