Notes: In the first three columns, 1979 to 1977 year-of-arrival values are taken as threshold because these are the most restrictive samples that are large enough. In columns (4) to (6), 1973 to 1971 year-of-arrival values are taken as threshold becuase since guestworker program ended in 1973. Standard errors are adjusted for clustering at the level of country of origin. Macro variables are three-year moving averages. Robust standard errors in brackets; * significant at 10%; ** significant at 5%; *** significant at 1%.
