Research Policy
The set of technological opportunities in a given industry is one of the fundamental determinants of technical advance in that line of business. We examine the concept of technological opportunity and discuss three categories of sources of those opportunities: advances in scientific understanding and technique, technological advances originating in other industries and in other private and governmental institutions, and feedbacks from an industry's own technological advances. Data from the Yale Survey on Industrial Research and Development are used to measure the strength of various sources of technological opportunity and to discern interindustry differences in the importance of these sources. We find that interindustry differences in the strength and sources of technological opportunities contribute importantly to explanations of cross-industry variation in R&D intensity and technological advance.

Brookings Papers on Economic Activity
In this paper, we describe the results of an inquiry into the nature of appropriability conditions in over one hundred manufacturing industries, and we discuss how this information has been and might be used to cast light on important issues in the economics of innovation and public policy. Our data, derived from a survey of high-level R&D executives, are informed opinions about the nature of an industry's technological and economic environment rather than quantitative measures of inputs and outputs.

Competition Policy International
To have the incentive to undertake research and development, a firm must be able to appropriate returns sufficient to make the investment worthwhile. The benefits consumers derive from an innovation, however, are increased if competitors can imitate and improve on the innovation to ensure its availability on favorable terms. Patent law seeks to resolve this tension between incentives for innovation and widespread diffusion of benefits. A patent confers, in theory, perfect appropriability (monopoly of the invention) for a limited time in return for a public disclosure that ensures, again in theory, widespread diffusion of benefits when the patent expires.

... Por ej., Englash et al. (2004) distinguen tres formas de apropiación: reinterpretación, adaptación y reinvención. Esta idea de apropiación puede estar limitada a las actividades de las firmas, o incluir otras actividades sociales (culturales, educativas, etc.), enfocarse en algún tipo específico de tecnologías (por caso, las digitales) o no, etc. En cambio, desde la economía de la innovación, con el significante "apropiación" se alude a un conjunto de mecanismos y habilidades que operan a nivel microeconómico para transformar el conocimiento en cuasi rentas (Arundel, 2001;Cohen, Nelson y Walsh, 2000;González y Nieto, 2007;Levin et al., 1987). Esta última acepción incluye a la titularidad, pero como una posibilidad puntual dentro de las formas de apropiación, y no como su acepción general. ...

... On the other hand, public disclosure does not always ensure ultimate diffusion of an invention on competitive terms" (LEVIN et al., 1987, p. 783-784). Levin et al. (1987) describe the outcomes of an inquiry into appropriability conditions in more than one hundred manufacturing industries, by emphasizing differences between process and product innovations. Similarly to others contributions by NW, the focus was on the asymmetries. ...

... Following Levin et al. (1984Levin et al. ( , 1987, appropriability (Appro) is defined as the extent to which the innovative outcomes can be appropriated by the innovators themselves, while technological opportunity denotes the availability of useful information for innovation. The variable for appropriability is calculated based on the survey's scores regarding the effectiveness of nine methods of appropriation (e.g., patents to prevent duplication or to secure royalties, secrecy, lead time). ...

... The DOIL survey employs a representative sample of the population of firms in the U.S. manufacturing sector, with 5175 respondents at the business unit level. Unlike several other innovation surveys (e.g., Cohen et al., 2000;Levin et al., 1987), the DOIL survey is not restricted to R&D performers. It includes innovators, imitators, and firms that do not innovate by asking whether the firms had introduced a new product that is new to the market or new to the firm and requests further information about their key innovations (Arora et al., 2016b). ...

... Finally, we included an exogenous variable: the sector's technology intensity. Technological advancement varies across manufacturing sectors, affecting the adoption of new scientific and technological knowledge (Klevorick et al., 1995;Martínez-Senra et al., 2013). Notes: a On a 4-point Likert scale (0: no use; 1: low potential use; 2: medium potential use; 3: high potential use) Source: Authors' own work IJLSS Firms in highly dynamic technological sectors are better positioned to improve environmental management (Moyano-Fuentes et al., 2018). ...

... Universities are considered as "creators, interpreters of ideas and innovation, source of human capital, and key components of social infrastructure and social capital " [47] . Universities also play critical role in creating and transforming industries through industry transplantation, diversification of old industry into related new, and upgrading of mature industries [48] . Universities in the modern world are actively changing their policy towards commercialization of their research outputs in the form of licensing, patents, and spinoffs. ...

... Second, patent protection plays an outsized, almost unique role in pharmaceutical markets. An influential survey by Levin et al. (1987) of 650 corporate R&D managers found that they considered patents to be an especially effective means for encouraging innovation in the pharmaceutical industry. 10 A major reason patent protection is crucial for the pharmaceutical industry is that while large R&D investments are required for successful drug discovery, the costs of imitating novel drugs are often trivially small in comparison. ...
