#Expert Insight: Here’s what can happen when dollar stores move in

Dollar stores they're everywhere and on of America's fastest growing retail options. From the outside looking in, the idea of dollar stores seem like a win/win all around -cheaper food, cheaper toys, and just about cheaper everything on offer to consumers looking to save money. However, recent research by UConn Professor Rigoberto Lopez might be pulling back the curtain on the bad deal these new outlets are selling to consumers and communities. Dollar stores have proliferated in recent years, and a study by a University of Connecticut economist has found that they contribute to less healthful food choices in the neighborhoods where they open. That’s because independent grocery stores tend to close in the same areas where the dollar stores open, according to professor Rigoberto Lopez, whose research focuses on agricultural economics. “The dollar store expanding is the fastest-growing retail format, and we also have seen a lot of family, independently owned grocery stores going out of business,” Lopez said. “So we try to link the two and to find not just a statistical correlation, but also we find that indeed when the dollar store comes to the neighborhood these stores tend to go out of business as well.” The low-priced dollar store — primarily Dollar General, Family Dollar and its subsidiary, Dollar Tree — “is the most successful type of format that is proliferating all across the United States, especially in rural areas and food deserts, which are the more underserved areas,” Lopez said. According to the study, published in Applied Economic Perspectives and Policy, there were 35,000 dollar stores in the United States in 2019 and they were “among the few food retailers” that grew in revenue after the Great Recession of 2008-10, outperforming big box discounters and retail clubs. Between 2000 and 2019, dollar stores opening in a neighborhood resulted in a 5.7% drop in independent grocery store sales, a 3.7% decrease in employment and a 2.3% increase in the likelihood of the grocery stores closing, according to the research. The effects are three times more likely in rural than urban areas, the study found. The dollar stores tend not to offer fresh produce and meats, with foodstuffs being limited to canned and boxed goods. “In general they provide an unhealthier food assortment … and less services,” Lopez said. “They don’t have bakery, butchers, they don’t have a lot of these.” The article also discusses not just the economic aspects, but public health implications as well. Lopez said the dollar stores’ business model is “low prices, low cost, low quality. … But a lot of the food that they sell is not healthy. It’s processed foods that they can store. Keeping fresh food and vegetables costs money.” Dollar stores are not necessarily a negative, if there was not a grocery store in the area before, Lopez said. “Public health advocates, they’re against dollar stores, but a lot of people that visit the dollar store, they prefer to have a dollar store than not to have anything at all in some areas. … But in general … we find if they are driving some of the local businesses out, then that is the negative trend.” Food insecurity and the changing landscape of grocery stores are important topics, and if you have questions or are looking to cover, then let us help.

Cash-back fees at dollar stores and other retailers are steep, affect some communities disproportionately

Scripps  online

2024-09-06

Dr. Rigoberto A. Lopez is an economics professor at the University of Connecticut who says these practices tend to affect lower income communities disproportionately because many dollar stores tend to be located in these communities.

Lopez calls it a predatory practice because he says many of these communities where dollar stores are located tend not to have easy access to banks or other options for withdrawing a consumer's cash.

We love dollar stores in CT. But here’s what can happen when they move in: study

Climate change increases milk production

Dairy cows produce less milk when they get too hot, said Rigoberto Lopez, the corresponding author of the study and a professor of Agricultural and Resource Economics at the University of Connecticut. However, hot temperatures stimulate the growth of plants that cows eat to produce milk.

Consumer preferences for sustainably produced ultra-high-temperature milk in China

Journal of Dairy Science

2023

Contrary to ongoing declines in per capita milk consumption in the United States and Europe, per capita milk consumption in China is experiencing dramatic increases, making China one of the most dynamic global dairy markets. Meeting the rapid growth in milk demand presents environmental challenges under current dairy farm production in China. This article measures Chinese consumer valuation of environmentally sustainable milk and of correlated attributes such as food safety and geographic origin. The authors used a discrete choice experiment to collect survey data from a stratified sample of respondents in 5 cities.

Dollar store expansion and independent grocery retailer contraction

Applied Economic Perspectives and Policy

2023

This paper examines the effects of dollar store entry on independent grocery retailers in the United States between 2000 and 2019. We utilized an establishment‐level dataset comprising all grocery retailers and dollar stores in the country. Our findings indicate that dollar store entry is associated with a 5.7% decrease in sales, a 3.7% reduction in employment, and a 2.3% rise in the likelihood of independent grocery retailers quitting the business. These adverse entry effects are three times larger in rural than urban areas. Event studies indicate that the negative impact on sales and employment disappears gradually in urban areas but persists in rural communities.

Input and Output Market Power with Non-neutral Productivity: Livestock and Labor in Meatpacking

Centre for Economic Policy Research

2023

Market power can be present in both a firm’s product and input markets, allowing for supranormal profits to the detriment of social welfare. However, identification is challenging because it requires unbiased estimates of production elasticities under the interwoven presence of monopsony power and non-neutral productivity. We propose a way to measure market power in the product market and several input markets of a firm that is robust to biased technological change. The inference can be checked by assessing how much each market contributes to the gross profits of the firm. We illustrate the method with data from the highly concentrated US meatpacking industry, which is often suspected of exploiting livestock farmers and immigrant workers.
