This book considers a relatively new metric in complex systems, transfer entropy, derived from a series of measurements, usually a time series. After a qualitative introduction and a chapter that explains the key ideas from statistics required to understand the text, the authors then present information theory and transfer entropy in depth. A key feature of the approach is the authors' work to show the relationship between information flow and complexity. The later chapters demonstrate information transfer in canonical systems, and applications, for example in neuroscience and in finance. The book will be of value to advanced undergraduate and graduate students and researchers in the areas of computer science, neuroscience, physics, and engineering.

The spread of exotic grains is evidence that globalisation works
The world’s foremost expert on pricing strategy shows how this mysterious process works and how to maximize value through pricing to company and customer.
In all walks of life, we constantly make decisions about whether something is worth our money or our time, or try to convince others to part with their money or their time. Price is the place where value and money meet. From the global release of the latest electronic gadget to the bewildering gyrations of oil futures to markdowns at the bargain store, price is the most powerful and pervasive economic force in our day-to-day lives and one of the least understood.
The recipe for successful pricing often sounds like an exotic cocktail, with equal parts psychology, economics, strategy, tools and incentives stirred up together, usually with just enough math to sour the taste. That leads managers to water down the drink with hunches and rules of thumb, or leave out the parts with which they don’t feel comfortable. While this makes for a sweeter drink, it often lacks the punch to have an impact on the customer or on the business.
It doesn’t have to be that way, though, as Hermann Simon illustrates through dozens of stories collected over four decades in the trenches and behind the scenes. A world-renowned speaker on pricing and a trusted advisor to Fortune 500 executives, Simon’s lifelong journey has taken him from rural farmers’ markets, to a distinguished academic career, to a long second career as an entrepreneur and management consultant to companies large and small throughout the world. Along the way, he has learned from Nobel Prize winners and leading management gurus, and helped countless managers and executives use pricing as a way to create new markets, grow their businesses and gain a sustained competitive advantage. He also learned some tough personal lessons about value, how people perceive it, and how people profit from it.
In this engaging and practical narrative, Simon leaves nothing out of the pricing cocktail, but still makes it go down smoothly and leaves you wanting to learn more and do more―as a consumer or as a business person. You will never look at pricing the same way again.
Once, long ago, being richer meant working less.

Professor Arrow, one of the most brilliant minds in his field during the 20th century, became the youngest economist ever to earn a Nobel at the age of 51.
Kenneth J. Arrow, one of the most brilliant economic minds of the 20th century and, at 51, the youngest economist ever to win a Nobel, died on Tuesday at his home in Palo Alto, Calif. He was 95.
His son David confirmed the death.
I did not know that that the famous Monty Python spam sketch was recorded on 6 June 1970. At least, that’s the claim of a Tumblr obsessed with Minnesota in the 1970s. (Wikipedia says only that “[i]t premiered on 15 December 1970”.) However, I need no encouragement to share a programme on Spam that I made for BBC Farming Today back in 1997, a programme that was both very well received and a blast to make. the people at Hormel couldn’t have been nicer, and the butterfly spam balls weren’t bad either.
There’s so much more to spiced ham than one could have ever thought. It’s not only a great slice of Americana, but there’s some science and interesting economics behind the things that go into making it. Both a fun and fascinating episode.
Driven by technological progress, human life expectancy has increased greatly since the nineteenth century. Demographic evidence has revealed an ongoing reduction in old-age mortality and a rise of the maximum age at death, which may gradually extend human longevity. Together with observations that lifespan in various animal species is flexible and can be increased by genetic or pharmaceutical intervention, these results have led to suggestions that longevity may not be subject to strict, species-specific genetic constraints. Here, by analysing global demographic data, we show that improvements in survival with age tend to decline after age 100, and that the age at death of the world’s oldest person has not increased since the 1990s. Our results strongly suggest that the maximum lifespan of humans is fixed and subject to natural constraints.
The first generation of the digital revolution brought us the Internet of information. The second generation—powered by blockchain technology—is bringing us the Internet of value: a new, distributed platform that can help us reshape the world of business and transform the old order of human affairs for the better.
Blockchain is the ingeniously simple, revolutionary protocol that allows transactions to be simultaneously anonymous and secure by maintaining a tamperproof public ledger of value. Though it’s the technology that drives bitcoin and other digital currencies, the underlying framework has the potential to go far beyond these and record virtually everything of value to humankind, from birth and death certificates to insurance claims and even votes.
Perhaps not necessarily this particular book which appears to be on the overview side, but sometime this year I’d like to delve more deeply into the concept of blockchain and the tech behind it.

HIS inauguration is still six weeks away but Donald Trump has already sent shock waves through American business. Chief executives—and their companies’ shareholders—are giddy at the president-elect’s promises to slash burdensome regulation, cut taxes and boost the economy with infrastructure spending.
This article takes much the same view of Trump’s economic policies as I (and I’m sure many) do. I’ve been hoping every day for more than a year and a half that more politicians would take Cesar Hidalgo’s book Why Information Grows as the basis for their economic policies. Alas…
Highlights, Quotes, & Marginalia
American capitalism has flourished thanks to the predictable application of rules. If, at the margin, that rules-based system is superseded by an ad hoc approach in which businessmen must take heed and pay homage to the whim of King Donald, the long-term damage to America’s economy will be grave.
Such tariffs would be hugely disruptive. They would make goods more expensive for American consumers. By preventing American firms from maximising their efficiency using complex supply chains, they would reduce their competitiveness, deter new investment and, eventually, hurt workers’ wages across the economy. They would also encourage a tit-for-tat response.
The role of lobbyists will grow—an irony given that Mr Trump promised to drain the Washington swamp of special interests.
Nonetheless, Mr Trump’s approach is worrying. Unlike the Depression, when Hoover and then Roosevelt got companies to act in what they (often wrongly) saw as the national interest; or 2009, when Mr Obama corralled the banks and bailed out Detroit, America today is not in crisis. Mr Trump’s meddling is thus likely to be the new normal. Worse, his penchant for unpredictable and often vindictive bullying is likely to be more corrosive than the handouts most politicians favour.
Mr Trump’s mercantilism is long-held and could prove fierce, particularly if the strong dollar pushes America’s trade deficit higher (see article). Congress would have only limited powers to restrain the president’s urge to impose tariffs. More important, even if rash protectionism is avoided, a strategy based on bribing and bullying individual companies will itself be a problem.

But over time the damage will accumulate: misallocated capital, lower competitiveness and reduced faith in America’s institutions. Those who will suffer most are the very workers Mr Trump is promising to help. That is why, if he really wants to make America great again, Mr Trump should lay off the protectionism and steer clear of the bullying right now.
📖 On page 16 of 448 of Dealing with China by Henry M. Paulson, Jr.
A simple preface followed by an anecdote about the beginning of a deal relating to telecom. The style is quick moving and history, details, and philosophy are liberally injected into the story as it moves along. This seems both interesting as well as instructive.
Highlights, Quotes, & Marginalia
“There are some who believe that an immutable law of history holds that conflict is inevitable when a rising power begins to bump up against an established one. But no law is immutable. Choices matter. Lessons can be learned.”
“Prescriptions, after all, are easier to make than predictions.”
“Note taking allows Party and government officials to get quick reads on what went on at meetings they didn’t attend. […] Private meetings with senior government officials without recoring devices or note takers are rare and highly sought after.”
“…the so-called iron rice bowl, the cradle-to-grave care and support guaranteed by the government through the big companies people worked for.”
“The Party had made a simple bargain with the people: economic growth in return for political stability. That in turn meant Party control. Prosperity was the source of Party legitimacy.”
“Messages in China are sent in ways that aren’t always direct; you have to read the signs.”
“It was the nature of dealing with China: nothing was done until it was done.”

During decades the study of networks has been divided between the efforts of social scientists and natural scientists, two groups of scholars who often do not see eye to eye. In this review I present an effort to mutually translate the work conducted by scholars from both of these academic fronts hoping to continue to unify what has become a diverging body of literature. I argue that social and natural scientists fail to see eye to eye because they have diverging academic goals. Social scientists focus on explaining how context specific social and economic mechanisms drive the structure of networks and on how networks shape social and economic outcomes. By contrast, natural scientists focus primarily on modeling network characteristics that are independent of context, since their focus is to identify universal characteristics of systems instead of context specific mechanisms. In the following pages I discuss the differences between both of these literatures by summarizing the parallel theories advanced to explain link formation and the applications used by scholars in each field to justify their approach to network science. I conclude by providing an outlook on how these literatures can be further unified.
