We investigate induced retirement effects of the Norwegian early retirement program "AFP" and emphasizes effects caused by relocations of some individuals from disability pension and unemploy,emt to AFP. Our theoretical model predicts that AFP unembiguously induces more early retirement.

A standard approach to duality in stochastic optimization problems with constraints in L(infinite) relies upon the Yosida-Hewitt theorem. We develop an alternative technique which employs only "elementary" means. The technique is based on an e-regularization of the original problem and on...
