Immigration, Investment and Real Wages
Elise S. Brezis, Paul Krugman
NBER Working Paper No. 4563
When a country is the recipient of large-scale, politically motivated immigration -- as has been the case for Israel in recent years -- the initial impact is to reduce real wages. Over the longer term, however, the endogenous response of investment, together with increasing returns, may well actually increase real earnings. If immigration itself is not wholly exogenous, but responds to real wages, there may be multiple equilibria. That is, optimism or pessimism about the success of the economy at absorbing immigrants may constitute a self-fulfilling prophecy.
