Hysteresis describes a situation where high unemployment remains high for a long time and becomes difficult to fix, even after the economy starts to improve.

Key reasons for this include:

• Skill erosion: Workers who are unemployed for a long time often lose their professional skills, making it harder to get hired later.
• Loss of motivation: Being out of work for a long period can discourage people from actively looking for new jobs.
• Stigma effect: Employers may avoid hiring candidates who have been unemployed for a long time.
• Geographic isolation: Areas with weak economies may struggle to recover even when the rest of the country is doing well.

Essentially, hysteresis means that a temporary economic crisis can cause a permanent increase in the natural rate of unemployment, making the economic damage long-lasting.
