Computers have greatly improved the lives of economists. Computer networks may dramatically change the way we work. Already we have seen hints with electronic mail, mailing lists, on-line card catalogs, access to U.S. government data, and the start of an on-line working paper culture (nearly...

An acceleration in the growth of communications bandwidth in use and a rapid reduction in bandwidth prices have not accompanied the U.S. economy’s strong performance in the second half of the 1990s. Overall U.S. bandwidth in use has grown robustly throughout the 1990s, but growth has not...

Arrow’s Impossibility Theorem shows that transitive social preference is impossible. This note shows that in the general case of exchange, social preference need not be transitive. Indeed, it shows that social preference must be non-transitive to allow gainful exchange to maximize social...

We characterize a rule in cost spanning tree problems using an additivity property and some basic properties. If the set of possible agents has at least three agents, these basic properties are symmetry and separability. If the set of possible agents has two agents, we must add positivity. In...

The decisions made during the design process have a critical impact both on the design solution obtained but also on the design process itself. It can be observed that while the way in which products are developed differs not only across firms but within the same firm over time, what is being...

Most properties of binary relations considered in the decision literature can be expressed as the impossibility of certain ``configurations.'' There exists no condition of this form which would hold for a binary relation on a subset of a finite-dimensional Euclidean space if and only if the...
