The Economics of Immigration. Market-Based
Approaches, Social Science, and Public Policy
Edited by Benjamin Powell
The Economics of Immigration summarizes the best
social science studying the actual impact of immigration, which is found to be
at odds with popular fears. Greater flows of immigration have the potential to
substantially increase world income and reduce extreme poverty. Existing
evidence indicates that immigration slightly enhances the wealth of natives
born in destination countries while doing little to harm the job prospects or
reduce the wages of most of the native-born population. Similarly, although a
matter of debate, most credible scholarly estimates of the net fiscal impact of
current migration find only small positive or negative impacts. Importantly,
current generations of immigrants do not appear to be assimilating more slowly
than prior waves.
Although the range of debate on the consequences of
immigration is much narrower in scholarly circles than in the general public,
that does not mean that all social scientists agree on what a desirable
immigration policy embodies. The second half of this book contains three
chapters, each by a social scientist who is knowledgeable of the scholarship
summarized in the first half of the book, which argue for very different policy
immigration policies. One proposes to significantly cut current levels of
immigration. Another suggests an auction market for immigration permits. The
third proposes open borders. The final chapter surveys the policy opinions of
other immigration experts and explores the factors that lead reasonable social
scientists to disagree on matters of immigration policy.
