What, another paper on the new economy? When financial markets are raking through the debris of $8 trillion in lost equity value, and “.com” is a reviled four-symbol word, a paper on the impact of the new economy on productivity would seem as welcome as an analysis of the role of whales in the lighting revolution. In fact, the new economy (or, more precisely, information technologies) continues...

---------------------------------------------ABSTRACT-----------------------------------------We consider a distributed computer system in Wardrop equilibrium, i.e., situations where no user can reduce its own response time by unilaterally choosing another path, if all the other users retain their present paths. The Braess paradox is a famous example of paradoxical cases where adding capacity t...

The main aim of this paper is to determine the factors which enhance or temper firms’ private incentives to use communications technologies that are characterised by network externalities and allow firms to influence their rate of technological change or total factor productivity (TFP). As regards the impact of the network effect on TFP, we find that when the externality parameter is low, a sli...

this study was carried out to investigate the important characteristics in some cultivars/genotypes of persianwalnut (juglans regia l.), black walnut (j. nigra l.), and walnut inter-specific hybrids: paradox (j. hindsii × j.regia) and royal (j. hindsii × j. nigra) in kamalshahr research station in karaj in 2011-2012. in the study,vegetative vigor was evaluated based on trunk cross-sectional are...

In this paper I examine compatibilism and incompatibilism about whether the self can be both a subject an object in same awareness at time. While is old debate that many traditions of philosophy have contributed to, my point departure work A.C. Mukerji (an Indian philosopher modern era) who worked on possibility self-awareness by articulating, what he called, paradox ego-centricity. also consid...

Before considering the merits of the various proposed solutions to the Fermi paradox, this chapter presents some of the background. I first give a short biography of Enrico Fermi himself, focusing on just a few of his many and varied scientific accomplishments. I mention only those contributions to science that I refer to in later sections of the book. I ignore, for example, his contribution to...
