Macro studies

A study is a question stated precisely enough that the answer is a count. Does an inverted curve mean a recession is coming is not one. In every month since 1976 where the ten-year sat below the two-year, what did unemployment do over the following year is — and the answer is a list of dates and a spread, which anyone can check.

Each page names its conditions in full, lists every window that met them, and gives the sample size. None of them says what happens next. That is not modesty about the data; it is the rule these pages are built on.

The catalogue is a written list rather than every combination of series. Enumerating pairs would produce thousands of pages nobody asked a question to get.
