market concentration and efficiency, such that firms display an increase in efficiency when their relevant market concentration decreases. The above positions of Bain (1956) as well as
Collins and Preston (1969) are not only supportive of collusion but also of the efficiency-profitability hypothesis: profits are higher for bigger firms within a greater concentrated market as this concentration signifies greater efficiency through mass production. In particular, economies of scale was the greatest kind of efficiency that large firms could achieve in influencing their costs, granting them greater market share. Notably however, Rosenbaum (1994) observed that most studies assumed the relationship between actual market share and observed profitability by following the implication that large firms hold greater market share due to their efficiency, demonstrating that the relationship between these efficiency and market share is not clearly defined.
1953:. Originally, the Lorenz curve measured the inequality of income distributed with a population and ranked individuals from highest to lowest earnings. Therefore, in this context the Gini coefficient is located between the 45° line representing an equal distribution of income and the Lorenz curve representing the actual distribution of income within the population. In a market concentration context, the Lorenz curve can be plotted ranking firms' market shares from smallest to largest to simulate a concentration curve. The firms’ cumulative percentage shares would remain on the y axis and the cumulative percentage of sellers would remain on the x axis.

consensus. For example, a negative correlation was established by
Connelly and Hirschey (1984) who explained that the correlation evidenced a decreased expenditure on R&D by oligopolistic firms to benefit from greater monopolised profits. However, Blundell et al. observed a positive correlation by tallying the patents lodged by firms. This general observation was also shared by Aghion et al. in 2005.

1023:. Collins and Preston (1969) shared a similar view to Bain with focus on the reduced competitive impact of smaller firms upon larger firms. Demsetz held an alternative view where he found a positive relationship between the margins of specifically the largest firms within a concentrated industry and collusion as to pricing.

If market shares are expressed as decimals, an HHI of 0 represents a perfectly competitive industry while an HHI index of 1 represents a monopolised industry. Regardless whether the decimal or percentage HHI is used, a higher HHI indicates higher concentration within a market.
