Month and year time fixed effects and 95 % confidence band. Notes: Specifications from Table 3, left side, are FE 3; those from the right side are FE 4—based on a data set disaggregated by occupations and NUTS3 regions. The blue dots and the vertical red lines mark the point and 95 % interval estimates, and the interval is very small in some cases. In the left panel, the dots are linked with a line to illustrate temporal development. Time fixed effects with effect coding (the reference period is January 2000 for month fixed effects or 2000 for year fixed effects, respectively)
