In this paper we argue that government spending played a significant role in stimulating the wave of innovation that hit the U.S. economy in the late 1970s and in the 1980s, as well as the simultaneous increase in inequality and in education attainment. Since the late 1970’s U.S. policy makers...

It is well known that research and development (R&D) is an important engine for economic growth. Also, initial wealth inequality and subsequent economic growth are well known to be related. This paper links inequality and R&D-driven growth. It shows that in a class of economies where R&D is the...

Bank runs are relatively rare events characterized by highly pessimistic depositor’s expectations. How would pessimistic depositors expect to be treated in a bank run? How will this affect their behaviour? How can Banks handle this kind of risk? In the framework of a Diamond-Dybvig- Peck-Shell...

Firm success is often associated with the development of better products. Private firms undertake applied R&D seeking market advantage, by capitalizing on the freely accessible results of basic research. But unpatentable basic research often fails to address applied R&D open problems. What is...

What is the most innovation-enhancing level of patent protection for the new ideas generated within the framework of multi-stage sequential innovation? How does increasing early innovation appropriability affect basic research, applied research, education, and wage inequality? What does the...

In this paper we investigate wealth inequality/polarization properties related to the support of the limit distribution of wealth in innovative economies characterized by uninsurable individual risk. We work out two simple successive generation examples, one with stochastic human capital...

Ideas about what is "fair" above and beyond the individuals' position in the income ladder determine preferences for redistribution. We study the dynamic evolution of different economies in which redistributive policies, perception of fairness, inequality and growth are jointly determined. We...

Patent or article citations reflect the consequences of a published idea on the discovery of new ideas. We draw a simple theoretical model predicting that the shape of the future citations of an idea can reveal the complexity of its innovative research spillover. We apply this method to the...

In this paper we argue that government procurement policy played a role in stimulating the wave of innovation that hit the US economy in the 1980s, as well as the simultaneous increase in inequality and in education attainment. Since the early 1980s U.S. policy makers began targeting commercial...
