Pensions and Productivity [PDF ebook] 

Employers typically view their investment in pension plans as a means of providing retirement income for their workers. Economists, on the other hand, view pension programs as a way to increase workplace productivity. Dorsey, Cornwell and Macpherson explore the theoretical and empirical basis for this perspective and, in the process, offer a complete and up-to-date discussion on the productivity theory of pensions.
