Technological diversification of U.S. cities during the great historical crises

Technological Diversification

Technological Diversification ∗

Why is GDP so much more volatile in poor countries than in rich ones? To answer this question, we propose a theory of technological diversification. Production makes use of different input varieties, which are subject to imperfectly correlated shocks. Technological progress takes the form of an increase in the number of varieties, raising average productivity. In addition, the expansion in the ...

the effect of e-64 on the developmental competence of sheep cocs during in vitro maturation

in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.

Economies at early stages of development are often shaken by abrupt changes in growth rates, whereas in advanced economies growth rates tend to be relatively stable. To explain this pattern, we propose a theory of technological diversification. Production makes use of different input varieties, which are subject to imperfectly correlated shocks. Technological progress takes the form of an incre...

Technological Change and Cities

The United States is in the midst of a technological revolution, driven in large part by rapid advances in microelectronics. There has been much speculation about the impacts of the “information superhighway” on society as a whole, but surprisingly little is known about the potential effects of this technology revolution on the spatial distribution of jobs and people either broadly or in urban ...
