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.

As the U.S. economy emerges from the coronavirus recession, public policies to support women’s ability to return to work and stay in the workforce will be necessary for economic recovery. This study seeks to assess if paid sick leave reduces short-term income volatility and increases long-term economic security through improved job attachment among women, particularly those who are less likely to have access to paid sick leave in the absence of paid sick leave mandates. Using the American Community Survey, Slopen will conduct analyses at the state and county level using the five states and 21 counties that implemented paid sick leave as the treatment group. She will exploit the variation in the timing of the implementation of mandates at the state or county level using a difference-in-differences approach to estimate the effect of paid sick leave mandates on women’s labor force participation, continuity of employment, weekly hours worked, income, and poverty. She also will identify effects on subpopulations most likely to lack access to paid sick leave in the absence of mandates.

There is increasing evidence of monopsony power in labor markets, with implications of lower wages and higher inequality. One popular policy recommendation is to constrain such monopsony power through more organized unions of workers, such as in local bargaining councils—collections of trade unions and employers representing specific industry-regions that consultatively bargain over and set minimum wages and working conditions for those industry-regions. This project will study the effect of such “sectoral bargaining” using South African data. Using matched employer-employee tax data from the South African Revenue Service, Bassier will match these agreements to firms as demarcated by industry and location. There are currently 39 legally recognized bargaining councils in South Africa, each covering a specific industry-region. Bargaining councils are estimated to cover 40 percent of workers in the formal sector in South Africa, concentrated mainly in the manufacturing, construction, trade, and transport industries in addition to covering the public sector. This research could give insight into how sectoral bargaining could improve worker power and mitigate the effects of monopsonistic labor markets.

Central banks across the developed world are reconsidering their monetary policy frameworks and are frequently looking to academic research to inform the question of whether to stick with the dominant paradigm of inflation targeting or to adopt a new monetary policy regime. To address this question, Halperin and Caratelli will build a model where price stickiness is modeled in a substantially more realistic way, compared to other models, in order to explore whether it is optimal for central banks to use nominal income targeting rather than inflation targeting. The two researchers will examine whether nominal income targeting would mean that central banks would not have to tighten policy in response to strong wage growth, which could boost equitable growth.

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.

In virtually all areas of the U.S. healthcare service sector, physicians are barred from referring patients to entities in which they have an ownership stake. But this is not the case for the dialysis industry, which is exempt from such restrictions. Joint ventures between physicians and dialysis facilities exist at nearly 20 percent of facilities. This research will explore how physicians’ ownership ties with dialysis firms affect steering, spending, and outcomes. Using data obtained from a Freedom of Information Act request from the Centers for Medicare and Medicaid Services, Eliason, McDevitt, and Roberts will construct a first-of-its-kind dataset that tracks the ownership of dialysis facilities, including whether physicians have an ownership stake. They will add in data on dialysis providers and patients, including detailed Medicare claims and rich information on patient characteristics and health outcomes. An event-study analysis will allow the three researchers to test whether there is a clear trend-break in new patient arrivals and referrals when parties enter into a joint venture in order to examine how integration affects competition. The analysis will enable the researchers to study how patient caseloads and referrals at unintegrated facilities change after a nearby rival forms a joint venture, along with the impact of vertical integration on patient outcomes such as hospitalizations and mortality, as well as overall Medicare spending. Prior research has found that Black, Latinx, and low-income patients suffer disproportionately from kidney failure and often receive worse care, potentially making these groups especially vulnerable to providers’ growing market power and physicians’ conflicting interests.
