iMFdirect wrote a new blog post titled Which Way the Wind Blows
By Jeff Hayden You can call this our Bob Dylan issue. It may seem odd for an economics magazine to draw inspiration from the legendary singer/songwriter, but one of his most famous lines, “The times, they are a-changin,’” reverberated through our corridors as we put together this special issue on the global economy’s past and future. We weren’t humming the tune to pass the time. The lyrics seemed especially relevant to us this year, as we mark the 70th anniversary of the IMF and World Bank and the 50th anniversary of F&D. The world has seen a staggering amount of change in the past seven...

Journal of Finance wrote a new blog post titled The People in Your Neighborhood: Social Interactions and Mutual Fund Portfolios
We find that socially connected fund managers have more similar holdings and trades. The overlap of funds whose managers reside in the same neighborhood is considerably higher than that of funds whose managers live in the same city but in different neighborhoods. These effects are larger when managers share a similar ethnic background, and are not explained by preferences. Valuable information is transmitted through these peer networks: a long-short strategy composed of stocks purchased minus sold by neighboring managers delivers positive risk-adjusted returns. Unlike prior empirical work,...

The Financial Services Club wrote a new blog post titled Digibank: the next generation of banking
I'm having this conversation about what a digital bank is all about and suddenly a light switches on. This light goes to the core of why I keep saying that digital banks are built upon digital infrastructure, and not an evolution of channels to be another one built upon existing infrastructure. The light bulb moment goes like this. Customer engagement in a digital world In the new world, the customer will first engage with the bank digitally. It will come from some point of contact through their social media. A friend likes the bank on Facebook or tweets about them. It’s something...

The Aleph Blog wrote a new blog post titled Q&A with Guy Spier of Aquamarine Capital
In the near future, I will be writing a a review of Guy Spier’s The Education of a Value Investor, which will be released next week.  Until then, to whet your appetite, here is an 11 question Q&A that I did with Guy, for which I give him thanks, because his time is valuable.What company have you owned the past that was the most surprising to you? (In prospect or in retrospect)I think that many have surprised me in one direction or another, but one of the more memorable was Duff and Phelps Credit rating – which I purchased in the mid-1990’s at a 7 Price to Earnings ratio. The company...

Complexity Digest wrote a new blog post titled ECCS'14: Satellite Meeting Information Processing in Complex Systems (IPCS'14)
All systems in nature have one thing in common: they process information. Information is registered in the state of a system and its elements, implicitly and invisibly. As elements interact, information is transferred. Indeed, bits of information about the state of one element will travel – imperfectly – to the state of the other element, forming its new state. This storage and transfer of information, possibly between levels of a multi level system, is imperfect due to randomness or noise. From this viewpoint, a system can be formalized as a collection of bits that is organized...

Complexity Digest wrote a new blog post titled An Evolutionarily Conserved Prion-like Element Converts Wild Fungi from Metabolic Specialists to Generalists
[GAR+] is a protein-based element of inheritance that allows yeast (Saccharomyces cerevisiae) to circumvent a hallmark of their biology: extreme metabolic specialization for glucose fermentation. When glucose is present, yeast will not use other carbon sources. [GAR+] allows cells to circumvent this “glucose repression.” [GAR+] is induced in yeast by a factor secreted by bacteria inhabiting their environment. We report that de novo rates of [GAR+] appearance correlate with the yeast’s ecological niche. Evolutionarily distant fungi possess similar epigenetic elements...

Complexity Digest wrote a new blog post titled Entropy | Special Issue : Information Processing in Complex Systems
All systems in nature have one thing in common: they process information. Information is registered in the state of a system and its elements, implicitly and invisibly. As elements interact, information is transferred and modified. Indeed, bits of information about the state of one element will travel—imperfectly—to the state of the other element, forming its new state. This storage, transfer, and modification of information, possibly between levels of a multi level system, is imperfect due to randomness or noise.

Complexity Digest wrote a new blog post titled The Big Ratchet: How Humanity Thrives in the Face of Natural Crisis (by Ruth DeFries)
Our species long lived on the edge of starvation. Now we produce enough food for all 7 billion of us to eat nearly 3,000 calories every day. This is such an astonishing thing in the history of life as to verge on the miraculous. The Big Ratchet is the story of how it happened, of the ratchets—the technologies and innovations, big and small—that propelled our species from hunters and gatherers on the savannahs of Africa to shoppers in the aisles of the supermarket.The Big Ratchet itself came in the twentieth century, when a range of technologies—from fossil fuels to...

Complexity Digest wrote a new blog post titled Morphogenesis in Living Systems (edited by Nadine Peyriéras)
This contributed volume presents interdisciplinary approaches which currently revolutionize the representation of the morphogenesis of living systems. The book introduces concepts from complex systems theory and explores how these concepts lead to quantitative approaches of living systems dynamics. It discusses whether new trends in the quantitative observation of living systems indicate a new paradigm of formal and applied epistemology for the reconstruction of living systems multiscale dynamics. The volume collects a number of articles from interdisciplinary teams, most of the authors were...

Complexity Digest wrote a new blog post titled The Myth of Mirror Neurons: The Real Neuroscience of Communication and Cognition (by Gregory Hickok)
An essential reconsideration of one of the most far-reaching theories in modern neuroscience and psychology.In 1992, a group of neuroscientists from Parma, Italy, reported a new class of brain cells discovered in the motor cortex of the macaque monkey. These cells, later dubbed mirror neurons, responded equally well during the monkey’s own motor actions, such as grabbing an object, and while the monkey watched someone else perform similar motor actions. Researchers speculated that the neurons allowed the monkey to understand others by simulating their actions in its own brain.Mirror...

Complexity Digest wrote a new blog post titled One Plus One Equals One: Symbiosis and the evolution of complex life (by John Archibald)
We are in the midst of a revolution. It is a scientific revolution built upon the tools of molecular biology, with which we probe and prod the living world in ways unimaginable a few decades ago. Need to track a bacterium at the root of a hospital outbreak? No problem: the offending germ's complete genetic profile can be obtained in 24 hours. We insert human DNA into E. coli bacteria to produce our insulin. It is natural to look at biotechnology in the 21st century with a mix of wonder and fear. But biotechnology is not as 'unnatural' as one might think. All living organisms use the same...

Mathematical Finance wrote a new blog post titled A NOTE ON THE QUANTILE FORMULATION
Many investment models in discrete or continuous‐time settings boil down to maximizing an objective of the quantile function of the decision variable. This quantile optimization problem is known as the quantile formulation of the original investment problem. Under certain monotonicity assumptions, several schemes to solve such quantile optimization problems have been proposed in the literature. In this paper, we propose a change‐of‐variable and relaxation method to solve the quantile optimization problems without using the calculus of variations or making any monotonicity assumptions. The...

Mathematical Finance wrote a new blog post titled OPTIMAL INVESTMENT IN CREDIT DERIVATIVES PORTFOLIO UNDER CONTAGION RISK
We consider the optimal portfolio problem of a power investor who wishes to allocate her wealth between several credit default swaps (CDSs) and a money market account. We model contagion risk among the reference entities in the portfolio using a reduced‐form Markovian model with interacting default intensities. Using the dynamic programming principle, we establish a lattice dependence structure between the Hamilton–Jacobi–Bellman equations associated with the default states of the portfolio. We show existence and uniqueness of a classical solution to each equation and characterize them in...
