Runs the exposure-weighted IV at the shock level (see [ssb_aggregate()]).
The point estimate equals the location-level shift-share estimate; the
shock-level heteroskedasticity- or cluster-robust standard error here is the
natural shock-level analogue of the AKM exposure-robust SE.
Usage
ssb_shock_iv(design, cluster = NULL, level = 0.95)
Arguments
- design
An [ssb_design()] object.
- cluster
Optional vector (length = number of shock-cells) grouping
shocks into clusters for the shock-level SE.
- level
Confidence level for the reported interval.
Value
A one-row `data.frame` (class `ssb_shock_iv`) with `estimate`,
`std.error`, `conf.low`, `conf.high`.
