Why would any well-informed person buy life insurance instead of investing the premiums directly with the expectation of earning more than a 2.5% return?

People who express certain genes in the dopamine system tend to be curious, creative, spontaneous, energetic, and mentally flexible. They are risk-takers and seek novelty. People who have high serotonin activity (or who take SSRI antidepressants) are more sociable, more eager to belong. They’re quite traditional in their values and less inclined toward exploration. People expressive of the testosterone system are tough-minded, direct, decisive, skeptical, and assertive. They tend to be good at what we called rule-based systems—engineering, computers, mechanics, math, and music. And people who are expressive of the estrogen/oxytocin system tend to be intuitive, imaginative, trusting, empathetic, and contextual long-term thinkers. They are sensitive to people’s feelings, too, and typically have good verbal and social skills.

How AI could change computing, culture and the course of history | The Economist

As a way of presenting knowledge, llms promise to take both the practical and personal side of books further, in some cases abolishing them altogether. An obvious application of the technology is to turn bodies of knowledge into subject matter for chatbots. Rather than reading a corpus of text, you will question an entity trained on it and get responses based on what the text says. Why turn pages when you can interrogate a work as a whole?

A meta-analysis is a study that looks at lots of previous studies and analyses all of the data together to increase the number of people studied and to look at the information in a consistent way. A meta-analysis looking at observational studies investigating statins and the risk of dementia looked at data from 11 studies, involving over 23,000 participants, who had been taking statins for between 3 and nearly 25 years on average. When all of the data was analysed together, the researchers found that those people taking statins had a 29 per cent reduced risk of developing dementia.

Interest Rate Parity (IRP) Definition, Formula, and Example
April 30, 2023QT:{{”
Forward Exchange Rate
An understanding of forward rates is fundamental to IRP, especially as it pertains to arbitrage. Forward exchange rates for currencies are exchange rates at a future point in time, as opposed to spot exchange rates, which are current rates. Forward rates are available from banks and currency dealers for periods ranging from less than a week to as far out as five years and more. As with spot currency quotations, forwards are quoted with a bid-ask spread.
The difference between the forward rate and spot rate is known as swap points. If this difference (forward rate minus spot rate) is positive, it is known as a forward premium; a negative difference is termed a forward discount.
A currency with lower interest rates will trade at a forward premium in relation to a currency with a higher interest rate. For example, the U.S. dollar typically trades at a forward premium against the Canadian dollar. Conversely, the Canadian dollar trades at a forward discount versus the U.S. dollar.

The Capital Asset Pricing Model: Theory and Evidence (Digest Summary)
January 24, 2023https://www.cfainstitute.org/en/research/cfa-digest/2005/05/the-capital-asset-pricing-model-theory-and-evidence-digest-summary QT:{{”
The capital asset pricing model (CAPM) builds on the Markowitz mean–variance-efficiency model in which risk-averse investors with a one-period horizon care only about expected returns and the variance of returns (risk). These investors choose only efficient portfolios with minimum variance, given expected return, and maximum expected return, given variance. Expected returns and variance plot a parabola, and points above its global minimum identify a mean–variance-efficient frontier of risky assets.

The Marvels—And Mistakes—Of Supertall Skyscrapers – The Atlantic
January 1, 2023Great article. Thought the very intentional “wind shaping” was fascinating (e.g. the “blow through” floors at 432 Park). Maybe we’ll see fins next.
QT:{{”
This didn’t seem unrelated to a lawsuit that 432 Park’s condo board has filed against the building’s developer. The plaintiffs claim that the building is riddled with more than 1,500 defects that have led to leaks, cracks, electrical explosions, and elevator shutdowns that trapped people for hours—as well as “horrible and obtrusive noise and vibrations,” including clicks, creaks, and a trash chute that thunders “like a bomb.”
….
diffusing the suction-filled whirlpools that sway a building as wind whips around its sides. You could notch the corners, like on Taipei 101, which resembles a towering stack of gifts. You could twist the building, like the Twizzler-esque Shanghai Tower. You could taper it to look like the tip of a paintbrush, like the Lakhta Center, or cut out sections to let wind blow through it, like the Shanghai World Financial Center, which is nicknamed “The Bottle Opener.” 432 Park’s designers decided to make it more porous: Every 12 stories, there are two “blow through” floors with cutouts for windows, but no glass. “}}

Weighted Average Cost of Capital (WACC) Explained with Formula and Example
December 4, 2022QT:{{”
WACC is calculated by multiplying the cost of each capital source (debt and equity) by its relevant weight and then adding the products together. In the above formula, E/V represents the proportion of equity-based financing, while D/V represents the proportion of debt-based financing.
…
Cost of equity (Re) can be a bit tricky to calculate because share capital does not technically have an explicit value. When companies reimburse bondholders, the amount they pay has a predetermined interest rate. On the other hand, equity has no concrete price that the company must pay. As a result, companies have to estimate cost of equity—in other words, the rate of return that investors demand based on the expected volatility of the stock.
…
Companies typically use the Capital Asset Pricing Model (CAPM) to arrive at the cost of equity (in CAPM, it’s called the expected return of investment). Again, this is not an exact calculation because firms have to lean on historical data, which can never accurately predict future growth.
…
Determining cost of debt (Rd), on the other hand, is a more
straightforward process. This is often done by averaging the yield to maturity for a company’s outstanding debt. This method is easier if you’re looking at a publicly traded company that has to report its debt obligations.
…
Businesses are able to deduct interest expenses from their taxes. Because of this, the net cost of a company’s debt is the amount of interest it is paying minus the amount it has saved in taxes. This is why Rd (1 – the corporate tax rate) is used to calculate the after-tax cost of debt.
