Here is an oversimplified vision of immigration: a substantial number of foreign unskilled workers enter the job market, causing a shift of the labor supply curve to the right (workers are suppliers of work), and changing the current equilibrium to another one with lower wages.

Different electoral rules have consequences on the strategic behavior of voters, political selection and policy outcomes.
