This paper proposes a tractable model to study the equilibrium diversity of technological progress and shows that equilibrium technological progress may exhibit too little diversity (too much conformity), in particular, foregoing socially bene…cial investments in “alternative”technologies that will be used at some point in the future. The presence of future innovations that will replace current...

The objective of this work is to provide a critical assessment of the basic methodology advanced in current macroeconomic theories to understand the relationship between technological progress and unemployment. The standard reference will be the so called natural unemployment schemes, that in what follows will be fully identified with equilibrium unemployment theories1. Our conviction is that u...

As the journal moves into its 10th year of publication, it (really those charged with its editorial well-being) continues to monitor developments in the field of proteomics, including activities in the related fields of genomics, transcriptomics, and metabolomics, with the view of introducing appropriate changes to accommodate them. This includes keeping our clinical and mass spectrometric iden...

Searching for technological and organizational innovations is a fundamental activity in social systems. Recent work in this area has focused on the notion of firms locally searching for high points on a “fitness landscape.” Here we show how the presence of neutral networks forming pathways of temporarily inconsequential changes can alter the potential of innovation in such worlds. In particular...

Science, technology, and innovation are essential to America’s continued economic growth, and can help achieve a wide range of national and global policy objectives. One currently underutilized tool for stimulating technological innovation is inducement prizes, which encourage efforts by contestants to accomplish a particular goal. A related policy instrument is an Advanced Market Commitment, u...

Within thirty years, we will have the technological means to create superhuman intelligence. Shortly after, the human era will be ended. Is such progress avoidable? If not to be avoided, can events be guided so that we may survive? These questions are investigated. Some possible answers (and some further dangers) are presented. _What is The Singularity?_ The acceleration of technological progre...

with regard to the importance of technological developments, senior enterprise managers should be aware of their organization's technological capabilities, changes and developments in the world, and also have information from their rivals' efforts in achieving new technologies, to be in line of their organization's technology developments. therefore a technological needs assessment model, is de...

water quality trading is a new approach in pollution control which satisfies water quality standards suggesting minimum cost solutions. this method uses tradable discharge permits based on pollution transfer coefficient in a river. this paper tries to establish a water quality trading program in a river basin according to transfer coefficients between pollution sources and evaluate cost effecti...
