South Africa has been experiencing platinum mine strikes. The Association of Mineworkers and Construction Union (AMCU), which is the majority union in the platinum belt, has been demanding R12 500 salary for its members (sanews.gov.za, 2014). The main employers Anglo American Platinum, Impala Platinum and Lonmin signed a wage agreement to end the 5 month strike. The agreement provides for a R1,000-a-month increase each year for the two lowest bands of employees (Vecchiatto, 2014).The Platinum strikes have caused what is called an adverse supply shock. Adverse supply shocks cause prices for a given amount of output to increase. Firstly, the strikes cause a decrease in production and when employers give in, an increase in wages. The price setting rate is given by the equation (W/P) W being wages and P Price, therefore an increase in wages causes price setting rate to increase. This increase in real wages will cause the mining companies to lay off employees and the natural rate of unemployment to decrease. Alternatively the wage increase can be put on consumers by an increase of the mark up. The price setting rate is given by the equation (1/1+m), therefore an increase in mark up (m) causes this rate to increase. The effect of the price setting increase is strong because the mining sector is a big employer. The industry is the largest employer, rivaled only by the public service which employs over a million
