A change in business structure can change how the economy operates and how economic variables relate to each other. A good example of this in Australia has been the increasing degree of competition in retailing, partly resulting from the entry of large global retailers to the Australian market.
It wasn't so long ago that Australia's retail landscape looked very different, with few of the global retailers that populated the shopping centres of large cities overseas. That has changed over the past decade, especially in groceries and clothing retail (Graph 7).
