The study investigates the effect of imposing an n-child policy by forecasting the population of the Philippines using a discrete age-structured compartmental model. Based on the results of the projection, a policy promoting a maximum of two children per couple leads to a transient stabilization...

One of the main goals stated in the proposals for the Common Fisheries Policy (CFP) reform is achieving maximum sustainable yield (MSY) for all European fisheries by 2015. In this paper, we consider the mechanism design problem for allocation of fishing rights to achieve MSY harvesting...

In this paper, a numerical model is developed where the role of species life history and age structure for the optimal management of a harvested resident species which is exposed to an invasive species. It is shown that reproduction and mortality characteristics of both species as well as age...

We study optimal fishery management in an age-structured, bio-economic model where two age classes can be harvested independently. We show that the optimal amount of catch differs with age classes, and we derive conditions under which it is optimal to harvest only one age class. Our main policy...

We characterize optimal fishery management in an age-structured, bio-economic model where two age groups are harvested with costly and imperfect selectivity. We show that a system of tradable fishing permits, each allowing to harvest a specific number of fish that differs with age group,...
