Up to a certain point, EITC payments increase as income increases, so it actually encourages work among low-wage employees. (Of course, it phases out at higher incomes, which discourages work).

Market orders are not the same as marketable orders. Market orders are instructions to buy or sell regardless of price. They're dangerous because in a sudden price move you may get a bad price (e.g., in a flash crash you may sell a

I've always found those advertisements weird. If consumers are rational and have good information, then the average savings from switching is the same as "how much do you have to pay someone to switch to Geico?". The higher i

There was one trade between 8:20 and 8:26, of 75 shares. This is fake news.

I've seen this use case: develop interactively using Matlab on a local machine, and then run a bunch of instances concurrently using Octave. You get the ergonomics of developing in Matlab, but you don't need hundreds of licenses.

I read through the blog posts, and it seems like the encryption is order-preserving. It's designed to leak enough information to be useful in prediction, but not enough for users to trade on it independently.

That paper uses simulated (i.e., fake) market data. The quote is just a bare assertion, not a conclusion. It's very difficult to identify spoofed orders in market data unless you're the exchange and know who sent all of the orders

Very bizarre reasoning: a misconfiguration can cause the strategy to do X => the strategy was designed to do X. Seems more like evidence for "quote stuffing is a bug": https://www.chrisstucchio.com/blog/201

This seems to be pretty textbook not insider trading (at least in the US). This is new, independent research about a company's products. At no point did you receive information from a company insider. You own your own information, so

The secondary mortgage market isn't a recent invention. It's been an explicit policy goal of the US government at least since the Great Depression.

Why wouldn't funding pharmaceutical research completely from taxes just lead to it being just as chronically underfunded as infrastructure currently is? And just as earmark-driven?

If you bought the shares after IPO, then someone sold them to you, and they missed out on all of those gains. Even in the IPO, it's very common that you're buying shares from insiders and private investors rather than from the com
