Plot Rotemberg weights (canonical GPSS figure)

Reproduces Figure 1 of Goldsmith-Pinkham, Sorkin and Swift (2020): each sector-cell is a bubble at its first-stage F-statistic (x) and just-identified estimate \(\hat\beta_n\) (y); bubble area is proportional to the absolute Rotemberg weight; positive-weight cells are blue open circles and negative ones amber open diamonds; the dashed horizontal line marks the overall estimate \(\hat\beta\).

Usage

max_size

Maximum bubble size.

label_top

If > 0, label this many top-weight sectors.

title

Optional plot title.

...

Ignored.

Value

A `ggplot` object.
