As the textbook indicates, labor mobility is the mechanism that labor markets use to improve the allocation of workers to firms. The economic reasons behind labor mobility are workers look into ways to improve their economics situations and firms want to employ more productive and cheaper workers. Americans are very mobile. Workers can relocate across state borders and firms can hire workers even from abroad. Can you share a story of labor mobility of someone you know or a relevant economics news? Make sure you analyze economic reasons behind the mobility with the theory you learn from this chapter. For example, many major companies including Google, Microsoft, Uber, Airbnb have announced to extend employee remote work policy to long term. How can we explain the consequence of such policy change and economic reasons behind the potential consequences in labor market?
