Penalty rates. A story to watch.

The Productivity Commission in Australia are looking at a variety of work practise's and this includes whether penalty rates are set appropriately.

Penalty rates are generally called 'overtime rates' in the rest of the English speaking world. It refers to the 'bonus' paid to workers who work extra hours over their usual working week or work at anti-social times, such as weekends. In Australia these rates continue to be set on a national level and for particular industry's.

Some argue that the rates set are too high. In some industry's the rates can be 200% of normal wages. The graph below shows the rates for the hospitality industry.

The traditional argument on penalty rates is that they lead to lower employment. The higher the wage rate then the lower the demand for labour. The same argument can be applied to the minimum wage. The graph below shows the effect of a penalty rate, PR, set above the market wage rate W. The effect is to lower employment by N - Nd hours when penalty rates apply. Notice that Ns - Nd hours of work are offered by workers, but are not taken up (involuntary unemployment).

Another way of looking at this is that penalty rates will cause firms costs to be higher. This leads to market prices being pushed up and so output, and so employment, in an affected industry is lower. The diagram below shows this with the industry or firm supply curve SPR reflecting the higher costs of penalty rates compared to no penalty rates, SNR.

There is some doubt about this analysis. When firms have a great deal of power relative to their employees, as they do in retail and hospitality, they might be able to force wage rates below market rates (W). This means that penalty rates protect workers from profit maximising employers. 

There is also not much evidence to suggest firms close down, or don't operate, when penalty rates apply. 

Below are some articles that look at this issue. The Productivity Commission will give its final report around July, it is worth being ready for it.

This is good analytical practice for IB and VCE economists. It might be a fruitful area for IA's or EE's for IB students.
