According to Hubbard et al. (2012 pp. 212), monopoly is “a market structure in which there is only one seller of a good or service who has no close substitute.” In addition to this, Coles argues that the entry of smaller companies and competition will eventually lead to higher prices, while The Masters Grocers Australia and Liquor Retailer Australia (MGA/LRA) want the government to step in and implement laws that prevent independent companies from anti-competitive behavior and implement a perfectly competitive market for small businesses. Another argument raised in the article is that "taking away independent retailers' ability to trade on days when their larger competitors are closed will ultimately have a detrimental effect on their survival." ' (The Sydney Morning Herald, 2015). In this case this would lead to a “lock-out point” (Hubbard et al, 2012 pp. 192) for smaller businesses, as there will be no competition in the market, meaning that smaller, independent businesses will close due to an inefficient level of production.
