But a speech by the assistant minister for competition, Andrew Leigh, reveals that businesses themselves and the way in which the major players are allowed to dominate industries is a significant drag on productivity growth.

In his Guardian Australia column, labour market and fiscal policy director Greg Jericho, reviews Dr Leigh’s speech and notes that over the past 20 years market concentration has increased across the whole economy. Over this time there has been a fall in the percent of new firms entering industries and also in established firms leaving. This produces a more sluggish economy where the need to innovate and pursue more productive operations is diminished. It also leads to firms being able to markup their prices by more each year as they consolidate their power, and also feel less need to offer better wages as the competition for labour falls.

While wages growth crucially requires fair bargaining arrangements that enables workers to negotiate better wages, when workers have fewer options to pursue better paying jobs at other more productive workplaces, the number of workers switching jobs declines and so too does the market pressure to pay wages.

Dr Leigh notes that this “decline in economic dynamism” needs greater policy focus, and his speech is an excellent corrective to the belief that improved productivity is all about taking away worker rights and giving more power to businesses to hire and fire.

Australian business groups and many on the conservative side of politics love to talk up free-market competition, but the past 20 years has shown the markets are less about competition and more about concentration. And while profits have risen, workers and households have been left worse off.
