Relationship between the ‘costs of goods sold’ of a firm in 2013 and the PageRank of the firm, which is calculated using the customer-supplier network for the entire sample period. The probability of a random jump in calculating PageRank is set at \(q=0.05\). The plots and dashed lines represent the mean and the confidence interval. The reference line shows a power law relationship with an exponent of 1.05.
