Since his seminal work of 1986 (“Increasing Returns and Long-Run Growth,” Journal of Political Economy 94(5), October, 1002−1037), three years before that movie, the economist Paul Romer explained that due to the non-rivalry of ideas – the fact, namely, that one person's use of an idea does not prevent others to make another use: to say, for example, 'I use your idea in a field other than yours' – innovations that arise from them enable the economy to free from the chains of diminishing returns for which, doubling the input, the output change less than proportionally.
