Here is an interesting article.Since it is a large file, I am pasting the link of an article by Jana B. Singer, University of Maryland School of Law" titled 'Alimony and Economic Efficiency". It critiques the economic justification from a feminist perspective and concludes( Section IV) with directions for an alternate approach to divorce related financial allocations.
If the link does not open, please paste it onto your browser and click to download the article.
