Rant of the day: The reimbursement process for seminar visits has really gotten insanely burdensome with universities treating a speaker getting a few hundred bucks reimbursement like a million dollar supplier.

Finance Borrowed this Equation from Physics✍️ The Black–Scholes equation (1973) is mathematically the same diffusion (heat) equation used to describe Brownian motion introduced by Albert Einstein in 1905. A risk-free portfolio behaves like heat flowing through a metal rod. Volatility is diffusivity. Payoffs are boundary conditions. Markets are just noisy physical systems. In 1997, the Nobel Prize in Economic Sciences was awarded for this idea, essentially a physics equation. Built on the Wiener process, the same math describes pollen grains, stock prices, quantum paths (Richard Feynman), and even early-universe fluctuations. Different fields. Same diffusion.

When I am making claims that Australia is becoming a more unequal society, I always point to South Africa and Brazil as societies without a functioning middle class. This chart shows wealth inequality by country. A quintessential question of our time is whether we want a middle class or not - currently we are actively shrinking it across the Western world.

BREAKING: The US government now may owe US companies $175 billion in tariff refunds, per CNN

Economics is mostly a bullshit field of study. It is specifically for people who can do a little bit of stats and calc and want to feel smart but too dumb to study physics or math. Most economic theories are built like this: they start with an assumption about human behavior. Then without checking if the assumption is true, they will pile on layers of sloppy math on it and come to all sorts of conclusions that obviously don’t hold up in the real world. Recently a couple of economists won the Nobel Prize for being the first to realize that assumptions about human behavior must be tested and they went out and did some field work, and proved that a lot of assumptions in economic theories about how humans behave with money are well just not true. I was working at a bank for 2 years and saw firsthand that economics PhDs tend to be the dumbest. These people are completely alien to the idea of first principles thinking and treat axioms as if they were written in the Bible. Also they don’t really understand what an axiom is. Economics only exists because your average normie is easily impressed buy math and midwits in power are not scientific enough to realize that it is all voodoo and keep taking economists seriously. I don’t blame them though, at some point they hit an intelligence wall and the average economist brain is simply not equipped to have meta level thoughts about their own field of study. I guess this is one of those bullshit jobs like HR, therapy, astrology, project management that will just stay around for a while cause most humans are either mid or retarded.













Really, people (both of them). This is cheap talk — people are just expressing the best/worst of their expectations of Trump. Until you show me investment/savings patterns consistent with these wild swings, these data are noise.

@FelixMeyerinck, @VesaPursiainen, and Markus Schmid study how competition shapes customer reactions to lawsuits using mobile phone data. Lawsuits lead to 4% fewer visits, especially in competitive areas. Revenues and returns also decline with competition. jfqa.org/wp-content/upl…
