Beveridge curve
A Beveridge curve, or UV curve, is a graphical representation of the relationship between unemployment and the job vacancy rate, the number of unfilled jobs expressed as a proportion of the labour force. It typically has vacancies on the vertical axis and unemployment on the horizontal. The curve, named after William Beveridge, is hyperbolic-shaped and slopes downward, as a higher rate of unemployment normally occurs with a lower rate of vacancies. If it moves outward over time, a given level of vacancies would be associated with higher and higher levels of unemployment, which would imply decreasing efficiency in the labour market. Inefficient labour markets are caused by mismatches between available jobs and the unemployed and an immobile labour force. The position on the curve can indicate the current state of the economy in the business cycle. For example, recessionary periods are indicated by high unemployment and low vacancies, corresponding to a position on the lower side of the 45° line, and high vacancies and low unemployment indicate the expansionary periods on the upper side of the 45° line. In the United States, following the Great Recession, there was a marked shift in the Beveridge curve. A 2012 International Monetary Fund (IMF) said the shift can be explained in part by "extended unemployment insurance benefits" and "skill mismatch" between unemployment and vacancies. (Wikipedia).
