Technological Revolutions

In skill-biased (de-skilling) technological revolutions learning investments required by new machines are greater (smaller) than those required by preexisting machines. Skill-biased (de-skilling) revolutions trigger reallocations of capital from slow(fast-) to fast(slow-) learning workers, thereby reducing the relative and absolute wages of the former. The model of skill-biased (de-skilling) re...

Long run economic growth has again become a major focus of economic theory. A perception of technological change as an economic process with externalities has motivated the development of aggregate models that generate different steady state growth paths. Economic history has also long been interested in long-run economic growth. This paper engages in a dialog between growth theory and the hist...

Industrial Revolutions and Consumption: A Common Model to the Various Periods of Industrialization

What was the role of consumption structure evolution in the industrialization phases of the Western world since the 18th century? To answer this question, we …rst ask the économical ad histoical literature. We idetify the main phases of consumption structure evolution and establish a plausible link between consumption structure evolutions and industrial revolutions. In particular, we show that ...

Oogenesis: Matrix Revolutions

The mechanism of egg-chamber elongation during Drosophila oogenesis has always been mysterious. A new study shows that the egg chambers spin around their long axis laying down polarised extracellular matrix, which acts as a molecular corset to restrict radial expansion.
