Migration and prices

One of the topics on the GCSE syllabus for RE is race and migration is a subset of that. Here's a new argument to add to those already covered.

prices in a city with an average proportion of new immigrants were 2.6 percent lower in December 1990 than in cities where no immigrants settled.
While the effect was consistent for almost all product categories, Lach found that the immigration effect was significantly stronger for products for which FSU immigrants constituted a larger share of the market, such as pork and vodka.
As Lach argues, newly arrived immigrants may be more price sensitive because of lower income and lack of brand loyalty. Immigrants, who may initially be unemployed, may also have more time to compare prices, and stores will tend to lower their prices to attract these new customers.
