In this article, we describe the various sorts of American Parisian options and propose valuation formulae. Although there is no closed-form valuation for these products in the non perpetual case, we have been able to reformulate their price as a function of the exercise frontier. In the...

The importance of fish size for price per kilo is studied using an inverse demand approach. Prices per kilo in different size categories of the same species differ significantly. This means that the average price for a species may change due to e.g., high-grading, growth overfishing or a...
