Norwegian cohort emigration

This paper introduces a counterfactual technique to estimate net emigration from Norwegian birth cohorts from 1846 to 1900. A main finding is that des pite strong fluctuations in annual emigration, the percentage reduction of each cohort due to emigration was surprisingly stable for all cohorts from 1846 to 1886, with net emigration of about 30%. for males and about 20% for females. Estimating an econometric model of annual male gross emigration b y single years of age 15-60 in the period 1870-1914, we find that previous net emigration from a cohort reduces later gross emigration from the same c ohort. The estimations also give some justification for attributing this to selectivity of emigration, in the sense that only a certain proportion of each cohort were potential migrants.
