Patents have long been assumed to provide firms with competitive advantage, but longitudinal results suggest that some types of patent content provide more enduring advantage than others do. The duration of advantage appeared to wane with time in the highly-dynamic U.S. communications-services industry during a period when technological changes occurred rapidly within it (1998–2012).
We study a dynamic learning model in which heterogeneously connected Bayesian players choose between two activities: learning from one's own experience (work) or learning from the experience of others (search). Players who work produce an inflow of information which is local and dispersed around the society. Players who search, instead, aggregate the information produced by others and facilitate its diffusion, thereby transforming what inherently is a private good into information that everyone can access more easily.
Revolutions are said to devour their children, as well as their parents. The Internet is no exception. Its success and impact have been overwhelming. But in the process it is also undermining its own technological, organizational, and economic foundations. If its origin was cutting-edge science and engineering, then its present is that of commerce and its future is that of entertainment. Yet that descent from lofty aspirations to popular diversions should not be seen as negative.
Media concentration has been an issue around the world. To some observers the power of large corporations has never been higher. To others, the Internet has brought openness and diversity. What perspective is correct? The answer has significant implications for politics, business, culture, regulation, and innovation. It addresses a highly contentious subject of public debate in many countries around the world. In this discussion, one side fears the emergence of media empires that can sway public opinion and endanger democracy.
How stocks are traded in the United States has been totally transformed. Gone are the dealers on NASDAQ and the specialists at the NYSE. Instead, a company's stock can now be traded on up to sixty competing venues where a computer matches incoming orders. High-frequency traders (HFTs) post the majority of quotes and are the preponderant source of liquidity in the new market.
Facebook is rapidly gaining recognition as a powerful research tool for the social sciences. It constitutes a large and diverse pool of participants, who can be selectively recruited for both online and offline studies. Additionally, it facilitates data collection by storing detailed records of its users' demographic profiles, social interactions, and behaviors. With participants' consent, these data can be recorded retrospectively in a convenient, accurate, and inexpensive way.
In countries undergoing de-industrialization — and which isn’t, among developed economies—an internet-based economic growth has been widely recommended as a way to create economic activity and thereby reduce the inequality of post-industrial society. In particular, the opportunities that the internet affords to the ‘creative workforce’ are believed to be an engine for employment, at a time when industrial jobs are being automated.
