    The probability of an accurate ball or strike call rises when the pitch is more likely to affect the outcome of the game. Umpires devote less attention, however, to calls made after or in anticipation of high-stakes decisions. Do individuals prioritize their limited supply of attention and focus more on important than on less-important decisions? In The Dynamics of Inattention in the (Baseball) Field (NBER Working Paper 28922) James E. Archsmith, Anthony Heyes,...

    Inequality - Figure 1.jpg
    Article
    Author(s): Edward N. Wolff
    Much attention has focused in the last few years on the issue of inequality. With recent proposals for a direct wealth tax, particular attention has been given to wealth inequality. My work also focuses on this issue. Here, I summarize studies of four different aspects. First, what are the general trends in wealth and wealth inequality over the last 60 years or so in the United States? I pay particular attention to the role of leverage and asset price movements in...
    Majors figure 1.jpg
    Article
    College major choice and its relationship to labor market outcomes has long been a topic of study for social scientists. Stretching back at least to the 1970s, researchers have recognized that the particular field, and not just the level of education, deserves attention. A number of studies have demonstrated that the choice of post-secondary field is a key correlate of future earnings, and that choice of college major may be an important factor in explaining earnings...

    Article
    Social Security is the primary source of income for most individuals aged 65 and up. Benefits depend on the worker’s earning history and on the age at which benefits are claimed, which may be as early as age 62. For each month beyond the Full Retirement Age (FRA) that the worker delays claiming (up to age 70), the monthly benefit amount is increased by the Delayed Retirement Credit (DRC). The DRC has increased substantially over time, from 3 percent per year of delay for...

    Article
    What are the health consequences when patients reduce their use of prescribed medications in response to higher out-of-pocket costs? In The Health Costs of Cost-Sharing (NBER Working Paper 28439), researchers Amitabh Chandra, Evan Flack and Ziad Obermeyer use the distinctive out-of-pocket cost-sharing features of Medicare Part D to demonstrate that such reductions can increase mortality. Their analysis makes use of the fact that two 65-year-old Medicare enrollees with...

    Article
    Analysis of a million firms founded between 2005 and 2010 finds that immigrants are more likely than native-born Americans to launch new enterprises of all sizes. In "Immigration and Entrepreneurship in the United States" (NBER Working Paper 27778), Pierre Azoulay, Benjamin Jones, J. Daniel Kim, and Javier Miranda show that compared with native-born Americans, immigrants play a larger role as employers than as employees. The researchers analyze data on more...

    Article
    Jobs in which self-employed individuals can regulate their working hours reduce the risk of launching new businesses by providing an income fallback. In the gig economy, software platforms provide self-employed individuals with easy access to flexible work opportunities. Gig workers contract with platform owners to provide on-demand services to their clients on a per-task basis. As independent contractors, these workers can determine how much they will work by...
