The book also offers a stimulating future vision to orient those with a longer-term perspective on the directions in which portfolio tools and related technology are advancing. - The only book with a coherent future vision of the e-portfolio field grounded in current practice - Brings together principles, technologies and practical guidance for users and practitioners

This paper provides a theoretical explanation for the persistent use of alphabetical name-orderings on academic papers in economics. In a context where market participants are interested in evaluating the relative individual contribution of authors, it is an equilibrium for papers to use alphabetical ordering. Moreover, it is never an equilibrium for authors always to be listed in order of relative contribution. In fact, we show via an example that the alphabetical name-ordering norm may be the unique equilibrium, although, multiple equilibria are also possible. Finally, we characterize the welfare properties of the noncooperative equilibrium and show it to produce research of lower quality than is optimal and than would be achieved if co-authors were forced to use name-ordering to signal relative contribution.
