According to foreign media Business Insider, the National Bureau of Economic Research published a new paper to infer consumer income based on consumer behavior and media consumption. The survey shows that the iPhone is the most common indicator of wealth.
“We measure the cultural differences between the two groups and infer the ability of the group to which they belong based on individual (i) media consumption, (ii) consumer behavior, (iii) time utilization or (iv) social attitude. In our data No brand can be a high-income forecast like having an Apple iPhone in 2016," Bertrand and Kamenica said in this article.
The paper explains that having an iPhone gives researchers a 69.1% chance of correctly inferring that the iPhone's owner is a so-called high-income group. Researchers describe high-income people as “the top quarter of household income.”
The survey shows that having an iPad is also a good indicator of wealth, but the ratio is slightly lower, only 66.9%. The researchers also found that having an Android phone also gives researchers a 59.5% chance of correctly predicting a consumer's wealth.
They wrote: “When you know if a consumer has an iPad in 2016, we can correctly infer whether the person’s income is in the first quarter or the last quarter, with an accuracy rate of 67%.” The study also showed that Having an Android phone or using Verizon services is also an important indicator of high income.
