Because the Soviet-Jews exodus was not foreseen ahead of time, Israel’s migration experience is amenable to the natural-experiment methodology. Disposable-income inequality in Israel, was roughly stable until the beginning of the 1990s, rose sharply following the immigration wave, even though no such change occurs with respect to the market-generated inequality. The chapter develops a stylized general equilibrium model with free migration, where wages are endogenous and redistribution policy is determined by (endogenously determined) majority voting. It address the issue of how migration can reshape the political balance of power, especially between skilled and unskilled and between native-born and migrants, and consequently to political-economic equilibrium redistribution policy of the welfare state.
