Portfolio fishing

Article Abstract:

The portfolio theory is a method of combining various cohorts to attain the desired combination of expectation and variance profit. The selection pattern has been applied to the Icelandic cod fishery and results have revealed that the historical level of effort is inefficient because of loss of average profit and excess variance. The method, which has been strictly microeconomic, should alco consider fluctuations in industry, as well as, consumer welfare in general.

A new efficiency criterion: the mean-separated target deviations risk model

Article Abstract:

A model for risk management is developed which considers variations in the response of investors to potential outcomes that are below expected returns. Previous models were formulated without regard for variations in outcome. The risk measure is computed by subtracting the above-target deviations from the below-target deviations. The usefulness of the model for different marketing strategies could be evaluated with determined efficient sets.
