Coronavirus: IPRC Updates

COVID-19, the disease caused by coronavirus, has spread fast, locally and globally, threatening health and ways of living across nations. Impacts are felt in politics, economics, public health and social interactions.

The Inequality and Policy Research Center (IPRC) is uniquely positioned to engage intersections of this historic event due to our location within the epicenter of Los Angeles/West Coast and the university’s vantage point facing the Pacific.

Additional Information

COVID-19 restrictions have eliminated some 30 percent of jobs in Los Angeles County, affecting 1.2 million workers. Losses have been most acute for lower wage industries, with roughly one in three lost jobs coming from industries with median pay under $30,000 per year. (Paul Bogaardt et al. IPRC Working Paper)

State and federal unemployment benefits provide many eligible individuals earning less than $50,000 a year with benefits exceeding their income. Higher income earners experience reduced monthly earnings. (Paul Bogaardt et al. IPRC Working Paper)


  • Small businesses are challenged to meet fixed operating costs such as rent, mortgage payments and insurance. Businesses need clear rules and coordinated responses across governments to reopen from the epidemic effectively. (RAND)
  • Programmers and other digital technologists bring code to bear against the novel coronavirus. New anti-COVID-19 tools and technologies must be fully accessible to everyone, while respecting digital privacy and personal autonomy. (Bill and Melinda Gates Foundation)
  • In addition to widespread job losses and reductions in work hours, families with children face challenges related to school and childcare closures necessitated by the pandemic, with growing disparities by family income and race/ethnicity. (Urban Institute)
  • While the issue is getting another look from lawmakers, it’s not clear whether a divided and distracted Congress will be able to reach a consensus on how best to regulate the vast amounts of data collected by digital contact tracing tools and other pandemic response efforts. (STAT)
  • The Federal Reserve is ready to use all available tools to help the U.S. economy endure the coronavirus pandemic, as attention shifts to whether politically divided Congress will agree to more fiscal aid. (Bloomberg) See Testimony of the Federal Reserve Chair Jerome H. Powell before the Senate Committee on Banking, Housing, and Urban Affairs here.
  • California is the first state to provide financial relief to undocumented immigrants as part of the state’s response to the coronavirus pandemic. A $125-million disaster relief fund creates partnership with philanthropic organizations. (California Department of Social Services)

Latest research news

  • COVID-19 severity correlates with patient age, lymphocytopenia, and cytokine storm. Viral genetic evolution does not significantly affect clinical outcomes. (Nature)
  • An antibody identified in the blood from a patient who recovered from SARS in 2003 has been shown experimentally to neutralize SARS-CoV2. (SciTechDaily)
  • An ecological study that included data from more than 3,000 US counties found that COVID-19 death rates were higher in areas with greater long-term exposure to particulate matter (PM2,5). (Xiao Wu et al. Harvard University)
  • Studying large COVID-19 clusters is difficult. Many countries have not collected the kind of detailed contact tracing data needed. And effective shutdowns have impeded researchers attempting to study superspreading events. (Science)
  • Americans who rely on the White House coronavirus task force for news coverage negatively assess media and are more likely to downplay the pandemic. (Pew Research Center)
  • Medical examiners are stepping up postmortem testing to determine whether non-hospital deaths are related to coronavirus. (Kaiser Health News)
