Norwegian economy
• Rapid economic growth due to oil and gas in the North Sea
• Most of the revenue from the North Sea invested in The Government Pension Fund - Global
• In 2007 the GDP per capita in Norway 76% higher than in OECD
• Low unemployment, 2-4% in recent years
• High demand for labour in the construction sector
• Norway also hit by the financial crisis, but is recovering
8
Migration theories
• People migrate when the expected income is greater than the current income, less migration costs (Todaro)
• Individual migration behavior is guided by the search for better economic opportunities (Borjas)
9
Methods for projecting migration
• A projection of population must rest, in part, on a projection of immigration. Yet most official immigration projections … rely on ad-hoc assumptions based on little theory and virtually no definable methodology (Howe and Jackson 2006)
• Official statistical agencies: Mostly trend extrapolation
• A few other attempts (Australia <–> New Zealand; British Columbia)
• EUROPOP 2008: net migration flows between member countries will convergence linearly to zero in the convergence year ( 2150)
10
Theoretical frameworkMigration from country of origin (o) to country of destination
(d) is a function of individual observables and unobservable characteristics:
ln wo = μo + εo where εo ~ N (0, σo2)
ln wd = μd + εd where εd ~ N (0, σd2)
Decision to migrate:
I = ln (wd/(wo + c)) ≈ (μd - μo - δ ) + εd - εo
c and δ: level of mobility costs.
Migration if I > 0
Probality of emigration from country o to country d:
P = Pr (εd - εo > - (μd - μo - δ ))
