In recent research, Yumin Hu, Luca Macedoni, and Mingzhi Xu explore how high income inequality can raise the costs of living. They compare grocery products around the U.S., finding that large retailers will increase the prices for their goods in places where income inequality is also high.
In new research, Dominic Smith and Sergio Ocampo show that retail concentration has increased in most markets across the United States, with the expansion of large retail chains driving the trend toward a more concentrated retail landscape. Their findings are based on new product-level census data for all U.S. retailers. They explain the implications of this increased concentration for the everyday shopping experience of clothing, electronics, groceries, and much more.
