Your friend has studied the Beveridge Curve that we graphed in class, and based on the shifts of that curve, she tries to convince you that either job-matching efficiency or the degree of mismatch changed sharply and quickly around 2010. What is one argument you could make to dispute her claim that recent changes in job-matching efficiency and mismatch were concentrated in a short time period? A.) Vacancies typically fall in recessions, and 2010 was a recessionary year. B.) The Beveridge Curve is not well-suited to study job-matching and mismatch among persons who were previously out of the labor force (N). C.) Both of the above. D.) None of the above.
