A recent study by Greg Kaplan found that young adults who move back home with their parents after a job loss can benefit from it. Living at home allows individuals to be choosier when looking for a new job, enabling them to wait for higher-paying opportunities and avoiding lower-earning jobs. This can result in lower long-term earnings...
