The dynamics of innovations and citations

Christian Ghiglino and Nicole Tabasso

Economics Letters, 2015, vol. 131, issue C, 94-97

Abstract: We present a model in which patent citations occur as new ideas are produced from combinations of existing ideas. An idea’s usability in this process is represented as an interval in a variety space of ideas, whose length determines the likelihood of citation. This process endogenously derives exponential aging of patents, which is consistent with empirical observations. The endogeneity of aging sets our process apart from the standard preferential attachment literature.
