In addition to the supply-side mechanisms described above, there may also be a number of
important demand-side effects, which could lead to an adjustment in equilibrium unemployment.
In addition, a number of possible “price push” factors may cause product demand changes to
impact on equilibrium unemployment. Some of these are wage-price stickiness (the traditional
Keynesian argument), changes in the marginal product of inputs, competitive interaction between
firms, changes in the real user-cost-of-capital and changes in the composition of demand
(Pichelmann and Schuh, 1997).
Fortunately the increasing trend in the NAWRU is gradually easing with a distinct turnaround of
late, which could in future result in a reversal in the rate of unemployment in the South African
economy. However, such a reversal will be short-lived if not supported by adequate labour
market reform, as will be momentarily outlined.
