Rent formation and distortions due to quotas in biological production processes

Production licenses with use restrictions that limit output are commonly used to regulate biological production processes. Such regulations are vulnerable to rent formation and production distortions that can end up subsidizing harmful environmental behavior. This paper develops a partial equilibrium model for a biological production process and use the model to study the impact of production quotas in Norwegian salmon aquaculture. Results suggest substantial regulatory rents capitalized in license values. Production has intensified leading to excessive stocking of fish per license, a shorting of the production period, and smaller produced fish. Our findings provide important insights for quota policies in food production, especially for cases where quotas are motivated by harmful environmental effects.
