This project seeks to answer two questions: What are the welfare effects of third-degree price discrimination, and what are the effects of third-degree price discrimination on the take-up of newer and better technologies? Goel will address this question in the context of a particular type of implantable medical device: defibrillators. The implantable medical device industry has three features that make it a compelling setting to study. First, manufacturers are able to prevent hospitals from disclosing prices, allowing them to charge different prices for the same device in different hospitals. Second, the industry is very concentrated, with more than 95 percent of the market share captured by just four firms. And third, there is a lot of product variety. On average, a manufacturer offers six brands of this particular device per year from 2014–2019. Goel will utilize a rich dataset with purchase volumes, prices, and characteristics of defibrillators, and will combine this with approval information from the U.S. Food and Drug Administration. She will then estimate a model of supply and demand, and conduct a counterfactual analysis in which third-degree price discrimination is banned in order to understand the dynamics of price discrimination.

Minimum Wages and Employment Composition
There is a large literature exploring the tension between increasing minimum wages in order to raise the hourly wages of workers and having these increases offset by reductions in overall employment or hours worked by low-wage employees. Understanding the distributional impacts of minimum wage increases is therefore essential. This project seeks to provide some of the first empirical evidence on how minimum wage reforms change firms’ occupational composition, distribution of hours, and scheduling practices. To do this, the authors will leverage shift-level microdata for the near-universe of employees and contract workers at U.S. nursing homes from the Payroll Based Journal program. The nursing home industry is an attractive setting for this research as it is a major employer of low-wage workers, especially certified nursing assistants, who provide the majority of patient care at nursing homes, are typically paid at or just above the minimum wage, and the majority of whom are immigrants and women of color. Moreover, many low-wage staff intend to work in the industry throughout their careers, in stark contrast to more heavily studied low-wage industries such as restaurants and retail, where many workers expect to leave the industry quickly. Accordingly, wage policies in the nursing home sector have the potential to not only affect the economic well-being of low-income workers but also shape gender and racial pay divides. In addition, the nursing home industry is of particular interest to regulators and policymakers since Medicaid and Medicare finance the vast majority of long-term care, and policies that affect the wages of employees in this sector will correspondingly affect state and federal budgets. Employment or composition changes may also have important consequences for quality of care.
Superstar Firms and Regional Disparities
This project investigates the relationship between two trends: the significant rise in regional inequality in the United States, with a small number of highly educated urban cities accounting for a growing share of national income, and the increasing dominance of large, multiregion services firms such as Amazon.com Inc., Walmart Inc., and Starbucks Corp., as reflected in measures of average firm size and market concentration. These “superstar” firms create high-paying, high-skill jobs in large cities and low-paying jobs in nonurban areas across the country, displacing local and regional competitors in the process and leading to increasingly unequal demand for skills across regions. Kleinman will utilize private data from Dun and Bradstreet and Burning Glass Technologies, as well as public data from the American Community Survey and the Panel Database on Incentives and Taxes. He will combine an empirical investigation of the relationship between firms’ spatial expansion and regional inequality with the development and quantification of a novel economic geography model that features expansion of multiregion firms to analyze the labor demand of firms across different markets and occupations.
The Effects of Redlining Maps: a Novel Estimation Strategy
This project investigates the causal effects of discriminatory assessment practices introduced by the New Deal-era federal agency, the Home Owners’ Loan Corporation. Specifically, the two researchers plan to examine HOLC’s systematic evaluation of neighborhoods and the maps it produced based on credit risk. Research has already led to the understanding that HOLC practices were a type of institutional discrimination. Data collected by the two researchers show that in 1930, about 86 percent of Black Americans lived in areas deemed hazardous (denoted in red on the maps, hence the term “redlining”) while almost 98 percent of the population in higher-rated areas was White. This research will measure how grade assignments affected the evolution of home values, income composition, and residential segregation in the short run and the long run. They will tackle the question by exploiting the fact that only cities over a certain population threshold were affected by the program. They will utilize a machine-learning algorithm to compare redlined neighborhoods with those that would have been redlined had the city been large enough to be affected by the program.
Extended-Family Wealth, Race, and the Transition to Homeownership
There is a significant racial divide in homeownership, as well as wealth, in the United States. In 2018, 73 percent of White householders owned their homes, compared to only 42 percent of Black householders, and the typical White household owned 20 times as much wealth as the typical Black household. A number of factors may explain this disparity, but one key contributor is the positive association between wealth and the ability of renters to transition to homeownership. This project will consider nonparental family members as potential sources of financial assistance to prospective homeowners. Utilizing the Panel Study of Income Dynamics, Bucknor will measure household wealth, parental wealth, grandparental wealth, and extended-family wealth, including businesses owned, transaction accounts, real estate, stocks, vehicles, home equity, and other assets, minus all debts. This research is poised to add to our understanding of intergenerational transmission of wealth and the far-reaching impacts of structural racism, and give insight into policies that may be effective in addressing persistent racial wealth inequality.
Homeownership Disparities and Access to Family Child Care
This project will use longitudinal data from two states to explore racial disparities in access to family child care centers by looking at rates of homeownership and disparities in homeownership by race. Family child care centers—licensed child care centers located within an operator’s home—make up a declining but still substantial proportion of the supply of formal child care. There are many obstacles to licensing a family child care center in a rental property, so areas with low rates of homeownership may experience a lack of access to this often more affordable child care option. Family child care centers also tend to have more flexible hours, making them especially valuable for parents working irregular or unpredictable schedules. Borowsky will conduct a market-definition analysis intended to approximate regions of common demand and supply. He will then evaluate the extent to which low rates of homeownership in a region are associated with low supply of family child care centers.
Understanding Amazon: Strategy and Welfare Implications
This project aims to provide a detailed, comprehensive analysis of the Amazon.com Inc. platform, its evolution, market power, and welfare implications. Gutierrez will utilize a massive dataset that has product information, alongside prices and sales ranks, for products sold on Amazon’s platform to produce three papers. The first will provide an overview of the Amazon platform and study the evolution and heterogeneity of fees in order to empirically test whether Amazon’s fees to sellers reflect market power. The second will consist of a structural analysis of reselling to test whether Amazon competing on its own platform is anticompetitive. And the third paper will analyze the impact of private label products. This research not only examines the Amazon platform but also provides empirical evidence on whether these types of activities can be anticompetitive.
Does Monetary Policy Work Through the Labor Market?
This project examines how increasing labor market polarization affects the transmission of monetary policy. Specifically, Morrison will examine how heterogeneity in worker substitutability with capital affects the role the labor market plays in the transmission of monetary policy. The research will estimate the importance of a heterogeneous worker-capital substitutability channel of monetary policy—investment spurred by monetary policy will have muted effects on aggregate consumption if workers whose labor is complementary with capital tend to have lower marginal propensities to consume. To investigate this phenomenon, she first plans to build and solve a model that captures this effect, then estimate the impulse-response functions of wages of workers in various skill categories to unexpected expansionary monetary shocks.
Who Weathers the Storm? The Unequal Effects of Hurricanes in the United States
Understanding the degree to which, and how, hurricanes have had disparate effects across disadvantaged and advantaged groups in the United States is key to policymakers’ ability to craft climate policy that ensures disadvantaged communities do not bear the brunt of our warming world. Most of the literature in this area has focused on average impacts, with relatively little attention paid to heterogeneity. But even in cases where no negative impacts of natural disasters are found, on average, some subgroups may experience substantial negative effects. This project leverages newly linked administrative tax data from the IRS and demographic information from the American Community Survey and decennial census with exogenous variation in individual-level exposure to all hurricanes in the United States between 1995 and 2019. The analysis seeks to uncover a deeper understanding of the consequences of and responses to hurricanes, and how these effects differ across socioeconomic and demographic groups.
Measuring Inequality in Real Time
U.S. unemployment due to the onset of the coronavirus pandemic was widespread, as was U.S. economic insecurity. In terms of consumption, aggregate retail sales fell by 16 percent in April 2020, the largest fall on record. While retail spending recovered by mid-July, spending on services remained significantly depressed. In contrast to aggregate spending and U.S. labor market data, there is little real-time data on the impact of the coronavirus pandemic on consumer spending inequality. This project will use a new transaction-level, real-time dataset from Earnest Research to measure consumer spending inequality in the United States and assess the impact of the pandemic on consumption inequality. The dataset contains information on a panel of 6 million households and is updated with a delay of just 1 week. Abdelwahed and Robbins will be able to study the outflows of spending, as well as the inflows of payments from wages and salaries, stimulus payments, and other government transfers into the households’ accounts, allowing them to construct a series on various ratios of spending between the top and bottom percentiles in order to study changes in consumer spending inequality along the distribution. They will also measure the effects of the pandemic on consumption of those who lost their jobs or experienced lower incomes and will compare them to individuals who retained their jobs. Abdelwahed and Robbins will estimate the impact of government stimulus payments and Unemployment Insurance on consumer spending inequality and consumption patterns. The data will be released publicly at the aggregate level at both the state and county levels, and the two researchers plan to release quarterly reports, providing other researchers and policymakers with a valuable new data source.
