This study compares estimates of technical efficiency obtained from the stochastic frontier approach and the Data Envelopment Analysis (DEA) approach using farm-level survey data for rice farmers in Bangladesh. Technical inefficiency effects are modelled as a function of farm-specific...

Government departments that regulate environmental management for mining have a range of choices about the timing and quality of rehabilitation. Economic theory suggests that the cost incurred by firms should relate to the social cost of the environmental damage, however, there has been little...

Optimal dynamic regulation of mineral extraction and environmental rehabilitation across diverse land assets is studied using discrete-time, distributed optimal control. An extension of Hotelling's Rule is derived that indicates the need to manage both processes over space and time to maximise...

The paper analyses the differences of technical, allocative, cost and scale efficiencies of irrigated and rain-fed rice farmers in Sri Lanka in two different perspectives; first, relative to a common metafrontier, defined as the boundary of an unrestricted technology set and second relative to...

Payments for ecosystem service outputs have become a popular policy prescription for a range of agri-environmental schemes. The focus of this paper is on the choice of sets of instruments in an ecosystem service principal-agent model that addresses adverse selection and moral-hazard. Results...

Co-movement between futures prices can arise when commodities are substitutes. Counterintuitively, Dawson and White fail to find a significant long-run link between feed barley and wheat prices on the London International Financial Futures Exchange. This relationship is re-examined using...
