By changing the nature of the native income distribution, immigration can also
affect the desirability of income redistribution. These changes affect different
population groups differently, setting up conflicts over both policies regarding the
scale and nature of immigration allowed and the appropriate fiscal response to that
immigration (Casarico and Devillanova, 2003). Political equilibrium can be expected
to respond to this and this has motivated several, typically theoretical, analyses of the
impact of immigration.
