> UK research suggests that immigration has a small impact on average wages of existing workers but more significant effects for certain groups: low-wage workers lose while medium and high-paid workers gain.
The wage effects of immigration are likely to be greatest for resident workers who are immigrants themselves.
Research does not find a significant impact of overall immigration on unemployment in the UK, but the evidence suggests that immigration from outside the EU could have a negative impact on the employment of UK-born workers, especially during an economic downturn.
The impacts of immigration on the labour market depend on the skills of migrants, the skills of existing workers, and the characteristics of the host economy. This means that research evidence on the labour market effects of immigration is always specific to time and place.
For both wages and employment, short run effects of immigration differ from long run effects: any declines in the wages and employment of UK-born workers in the short run can be offset by rising wages and employment in the long run.
