The article looks at how different types of people being employed or unemployed affect the job market during good and bad economic times. By studying data from the Current Population Survey, the researchers found that the types of people in the job market don't have a big impact on how many people find jobs during economic upswings or downturns. However, the length of time someone is unemployed does make a difference. The types of people in the job market do affect how many people lose their jobs during economic downturns. Interestingly, the positive effect of certain types of people on the job market during a recession can turn negative as the recession goes on.
