Answer:
Immigrants who match the existing population's characteristics blend into the economy, contributing to increased production and consumption, with overall small but real economic gains and potential short-term disruptions.
Step-by-step explanation:
When a large number of immigrants enter a country, they potentially affect the full employment output in several ways. If immigrants match the existing population in terms of age range, education, skill levels, family size, and occupations, they would blend into the economy and contribute to both increased production and consumption. With time for adjustment, the overall economy might witness a boost from the increased labor pool and consumer base. However, in the short term, there may be effects such as slightly lower wages for low-skill workers and budget strains for some local governments.
