At the same time, its availability creates significant potential for mistaken, misguided or malevolent uses of personal information. • The conundrum for the law is to provide space for big data to fulfill its potential for social benefit, while protecting citizens adequately from related individual and social harms. Current privacy law evolved to address different concerns and must be adapted to confront big data’s challenges.”

Big Data are often structured in such a way that essentially everyone in the file is unique, either because so many variables exist or because they are so frequent or geographically detailed, that they make it easy to reidentify individual pattarns.” • “There are no data stewards controlling access to individual data. Data are often so interconnected (think social media network data) that one person’s action can disclose information about another person without that person even knowing that their data are being accessed.”
instance, an attacker (or commercial actor) might instead infer a rule that relates a string of more easily observable or accessible indicators to a specific medical condition, rendering large populations vulnerable to such inferences even in the absence of PII. Ironically, this is often the very thing about big data that generate the most excitement: the capability to detect subtle correlations and draw actionable inferences. But it is this same feature that renders the traditional protections afforded by anonymity (again, more accurately, pseudosymmetry) much less effective.”

R&D rigidity. • The technological distance construct, proposed by Jaffe (1986), was originally intended as a measure of the degree of similarity between technological investment portfolios (which Jaffe called ‘technological positions’) of two different firms. • Thus, we estimated R&D rigidity by calculating the similarity between a firm’s current and previous technological investment portfolio. The more similar a firm’s current and previous portfolios, the more rigid its R&D resource allocation. Technological distance was calculated as follows.
• = 1 , 2 , ⋯ , • F it is 1 ☓ j vector, NP it denotes the number of patents obtained by firm i in year t and NP ijt is the number of patents obtained by firm i in field j in year t • Technological distance (P it ) between firm i’s technological position in year t (F it ) and year t-1 (F it-1 ) is obtained from • = Τ ∙ −1 ′ ∙ ′ −1 ∙ −1 ′ 1/2 • Technological distance assumes a value between 0 and 1, and it is unity if the two vectors are identical, which implies that the firm did not changes its investment profile at all between t-1 and t, and zero if the two vectors are orthogonal, which implies that the firm changed its technological position completely.
