Samples used in the analysis
| Displacement period | Restrictions on treatment group | Restrictions on control group | |
|---|---|---|---|
| Raw data | 1994–2002 | In employment at t* = 0 | In employment at t* = 0 |
| Sample 1 | 1995–2002 | In employment at t* = 0 and at least once from −4 ≤ t* ≤ −1 | In employment at t* = 0 and at least once from −4 ≤ t* ≤ −1 |
| Sample 2 | 1998–2002 | In employment at −4 ≤ t* ≤ 0 | In employment at −4 ≤ t* ≤ 0 |
| Sample 3 | 1998–2002 | In employment at −4 ≤ t* ≤ 0; only displaced at t* = 0 | In employment at −4 ≤ t* ≤ 0; never displaced |
