This research explores the historical roots and persistent effects of the division of labor in pre-modern societies. Exploiting a novel ethnic-level dataset, which combines geocoded ethnographic, linguistic and genetic data, it advances the hypothesis and establishes empirically that population...

This research explores the historical roots of the division of labor in pre-modern societies. It advances the hypothesis and establishes empirically that intra-ethnic diversity had a positive effect on the division of labor across ethnicities in the pre-modern era. Exploiting a variety of...

This research explores the historical roots of the division of labor in pre-modern societies. Exploiting a variety of identification strategies and a novel ethnic level dataset combining geocoded ethnographic, linguistic and genetic data, it shows that higher levels of intra-ethnic diversity...

This research examines theoretically and empirically the economic origins of ethnolinguistic diversity. The empirical analysis constructs detailed data on the distribution of land quality and elevation across contiguous regions, virtual and real countries, and shows that variation in elevation...

Through a functional approach relying on an information-energy duality of functions, markets economics is explored from the technological maturity viewpoint. The investment success probabilistic condition enables to calculate innovation-based investment functions which lead to a comparative...

Novelty is a basic requirement of patent law. An inventor cannot obtain a patent if the invention exists in the “prior art,” a term that generally refers to knowledge and technology already in the public domain. Interestingly, an earlier-filed patent document qualifies as prior art as of its...

This paper considers the prospect of a government patent buyout in a model of endogenous growth. To this end, I modify a standard quality ladder growth model by incorporating possibility of imitation, and rent protection activities (RPAs) by the innovator. The government finances the buyout by...

It is a triumph of technology and of economics that our computer chips are so universal. Countless applications are only possible because of the staggering variety of calculations that modern chips can compute. But, this was not always the case. Computers used to be specialized, doing only...

The patent system gives the courts discretion to tailor patentability standards flexibly across technologies to provide optimal incentives for innovation. For chemical inventions, the courts deem them unpatentable if the chemical lacks a practical, non-research-based use at the time patent...
