In this paper we integrate technology diffusion within Hotelling's exhaustible resource model. The modern technology is a conservation technology such as drip irrigation used with groundwater. Resource quality heterogeneity and rising water prices are responsible for the gradual adoption of the modern technology, and under reasonable conditions the diffusion curve is an S-shaped function of time. Without intervention, the diffusion process will be slower than is socially optimal, and optimal resource use tax will accelerate the diffusion of the conservation technology and slow down excessive resource depletion caused by market failure due to open access conditions.

The Faroe Islands cod fishery is analyzed for the period 1985-1992. It is shown that an approximately optimal and implementable fishery policy based on sustainability have increased the gross national income in the fishery by about 20%. This loss is due to an inoptimal organization of the fishery during that period combined with a very low cod stock at the end of 1992, which means reduced future catch possibilities. that the fishing capacity could have been reduced by about 1/3. The policy of sustainability is applied to the current situation in the fishery, and it is shown that the current …
