Sommario/riassunto |
|
This invaluable book is a unique collection of tributes to outstanding discoveries pioneered by Leon Chua in nonlinear circuits, cellular neural networks, and chaos. It is comprised of three parts. The first - cellular nonlinear networks, nonlinear circuits and cellular automata - deals with Chua's Lagrangian circuits, cellular wave computers, bio-inspired robotics and neuro-morphic architectures, toroidal chaos, synaptic cellular automata, history of Chua's circuits, cardiac arrhythmias, local activity principle, symmetry breaking and complexity, bifurcation trees, and Chua's views on nonline |

Sommario/riassunto |
|
An influential theoretical literature has observed that economic diversification can reduce risk and increase financial development. But causality operates in both directions, as a well functioning financial system can enable a society to invest in more productive but risky projects, thereby determining the degree of economic diversification. Thus, ordinary least squares (OLS) estimates of the impact of economic diversification on financial development are likely to be biased. Motivated by the economic geography literature, this paper uses instruments derived from topographical characteristics to estimate the impact of economic diversification on the development of finance. The fourth estimates suggest a large and robust role for diversification in shaping financial development. And these results imply that, by impeding financial sector development, the concentration of economic activity common in developing countries can adversely affect financial and economic development. |
