For example, suppose that, because of changes in technology or in the mix of industries and jobs, the mismatch between the skills of the unemployed and the needs of employers worsens.
Then, for a given number of job openings, the number of the unemployed who are qualified for those jobs is smaller and the unemployment rate is higher than it would have been before the mismatch problem worsened. Graphically, an increase in a skills mismatch would be reflected in a shift of the Beveridge curve up and to the right.
