the shape <strong>of</strong> this production function, as well as the demand and effort cost<br />

functions. The fishing effort approach is integrated with neoclassical<br />

production function analysis where labor and capital produce an effort<br />

frontier production function that can be estimated for selected Norwegian<br />

<strong>fisheries</strong>. Optimal vessel size and capital intensity can be estimated.<br />

Fishing vessels appear to be undersized but not too capital intensive.<br />

Hannesson, Rognvaldur (1983). "Optimal Harvesting <strong>of</strong> Ecologically<br />

Interdependent Fish Species." Journal <strong>of</strong> Environmental Economics<br />

and Management, 10:329-345.<br />

The optimal exploitation <strong>of</strong> a two-species predator-prey system is<br />

considered, using Lotka-Volterra type equations. Due to the density<br />

dependence <strong>of</strong> ecological efficiency, both species should be harvested<br />

simultaneously over a range <strong>of</strong> relative prices. Beyond the limits <strong>of</strong> this<br />

price range, either the prey species should be utilized indirectly by<br />

harvesting the predator, or the predator should be eliminated to maximize the<br />

prey yield. Neglecting harvesting costs, the simultaneous harvest <strong>of</strong> prey and<br />

predators requires that a unit <strong>of</strong> prey biomass increase in value by being<br />

"processed" by predators. Certain results from single species fishery models<br />

are shown not to apply to multispecies models. These are as follows: (i)<br />

Optimal regulation <strong>of</strong> a free access fishery may call for subsidizing instead<br />

<strong>of</strong> taxing the harvest <strong>of</strong> predator species. (ii) Increasing the discount rate<br />

may, at "moderate" levels, imply that the optimal standing stock <strong>of</strong> biomass<br />

increases instead <strong>of</strong> decreasing. (iii) a rising price <strong>of</strong> a falling cost per<br />

unit fishing effort <strong>of</strong> a species may raise and not lower the optimal standing<br />

stock <strong>of</strong> that species.<br />

Hannesson, Rognvaldur (1984). "Fisheries Management and Uncertainty."<br />

Marine Resource Economics, 1(1):89-96.<br />

This paper explores likely changes in the types and extent <strong>of</strong><br />

uncertainty resulting from increased regulation <strong>of</strong> <strong>fisheries</strong>. Specifically,<br />

<strong>fisheries</strong> management may be a principal source <strong>of</strong> uncertainty, and<br />

institutional uncertainty may be substituted for the uncertainty <strong>of</strong> nature.<br />

Hannesson, Rognvaldur (1985). "The Effects <strong>of</strong> a Fishermen's Monopoly in<br />

the Market for Unprocessed Fish." Marine Resource Economics,<br />

2(1):75-85.<br />

This paper considers the effects <strong>of</strong> granting a fishermen's sales<br />

organization exclusive rights to sell unprocessed fish. On the assumption<br />

that the fishermen's monopoly is able to discriminate between plants and end<br />

use alternatives in its pricing policy, the conditions for pr<strong>of</strong>it maximization<br />

are derived and compared with the conditions for social efficiency. It is<br />

found that the monopoly would be efficient if its costs for obtaining the fish<br />

are identical to the social costs, the marginal processing cost is constant,<br />

and either the price <strong>of</strong> the finished product is constant or the product is<br />

exported so that consumer's surplus is not a part <strong>of</strong> the social benefit. A<br />

fishermen's monopoly may thus achieve the objectives <strong>of</strong> an export cartel.<br />

When the marginal processing cost is rising the monopoly will over conserve<br />

the fish resource, provided that its cost <strong>of</strong> providing the fish is not<br />

sufficiently below the social cost. Finally, the analysis is extended to the<br />

special case in which processors have established a price discriminating<br />

monopoly in the market for the finished products but distribute the resulting<br />

pr<strong>of</strong>it through higher accounting prices while leaving individual processors to<br />

decide how much fish to buy for processing. This system passes the benefits<br />

from price discrimination in the markets for finished products on to the<br />

fishermen's monopoly.<br />
