Similarity of Symbol Frequency Distributions with Heavy Tails

A mathematical technique for comparing large symbol sets suggests that less frequently used words are mainly responsible for the evolution of the English language over the past two centuries.

Parasites Are Us

See on Scoop.itPapers

But if the mitochondria are me, doesn’t this mean I have two sets of genes? Aren’t I a mosaic of both my own cellular DNA and that of my mitochondria? The fact is that all of the “others”—whether they are parasitic or mutualistic, cheaters or straight-shooters, long-term residents or one-night stands—have a significant characteristic in common: They each carry their own DNA. And this means that, for however long they are inside their host’s body, two genetically distinct organisms are living under the same skin and, to one extent or another, are biologically intertwined. Deep down, at the core of our tissue, we are a gigantic, symbiotic array, a ragtag assortment of organisms. All of these are to some degree us.

Gold is the Spectre Haunting our Monetary System

For a century, elites have worked to eliminate monetary gold, both physically and ideologically.

This began in 1914, with the UK’s entry into the First World War. The Bank of England wanted to suspend convertibility of bank notes into gold. Keynes counselled wisely that the bank should not do so. Gold was finite, but credit elastic.

By staying on gold, the UK could maintain its credit, and finance the war effort. This transpired. The House of Morgan organised massive credits for the UK, and none for Germany. This finance was crucial, and sustained the UK until the US abandoned neutrality and tipped the military balance against Germany.

Despite formal convertibility of sterling to gold, the Bank of England successfully discouraged actual conversion.

Gold sovereigns were withdrawn from circulation and turned into 400-ounce bars. This form of bullion limited gold ownership to the wealthy, and confined gold’s presence to vaults. A similar disappearance of gold as a circulating currency occurred in the US.

Towards a Rational Theory of Heuristics

The third in a series of excerpts from Minds, Models and Milieux: Commemorating the Centennial of the Birth of Herbert Simon. Gerd Gigerenzer Herbert Simon left us with an unfinished task: a theory of bounded rationality. Such a theory should make two contributions. For one, it should describe how individuals and institutions actually make decisions. Understanding this process would advance beyond “as-if” theories of maximizing expected utility. Second, the theory should be able to deal with situations of uncertainty where “the conditions for rationality postulated by the model of neoclassical economics are not met” (Simon, 1989, p. 377). That is, it should extend to situations where one cannot calculate the optimal action but instead has to “satisfice,” that is, find either a better option than existing ones or one that meets a set aspiration level. This extension would make decision theory particularly relevant to the uncertain worlds of business, investment, and personal affairs.

The Keynesian House Of Denial

See on Scoop.itGold and What Moves it.

We use the term “Keynesian” loosely to stand for economic interventionists of all schools. The followers of JM Keynes and Milton Friedman alike fit that category. So do some of the more rabid supply siders who claim the power to stimulate ultra-high economic growth with the tools of tax policy alone.

The common denominator is economic statism. That is, the assumption that the state, including its central banking branch, is indispensable to economic progress and prosperity.

As the various denominations of the Keynesian economic church have it, capitalism is always veering toward the ditch of under-performance and recession when left to its own devices and natural tendencies; and, if neglected by the wise policy-makers of the central state too long, it lapses toward outright depression and collapse.
