Knowledge Spillovers: an Evidence from the European Regions
Journal of Open Innovation: Technology, Market, and Complexity Article Knowledge Spillovers: An Evidence from The European Regions Arkadiusz Kijek * and Tomasz Kijek Institute of Economics and Finance, Maria Curie-Sklodowska University, 20-031 Lublin, Poland; [email protected] * Correspondence: [email protected] Received: 15 July 2019; Accepted: 4 September 2019; Published: 6 September 2019 Abstract: The article deals with the issue of knowledge spillovers in the European regions. For this purpose, a standard Knowledge Production Function (KPF) approach was extended by the application of spatial econometrics methods. Our analysis started from the construction of the alternative structures of the spatial weight matrices. These matrices were based on technological and institutional proximities, which represent compelling alternatives to geographic proximity regarded as a kind of all-encompassing connectivity measure. The next step in our analysis was the modeling of regional knowledge generation processes. We treated R&D expenditures and human resources in science and technology as the input measures and patent applications to the European Patent Office as the output measure in our basic and extended models. The results show that the scope and direction of knowledge spillovers are sensitive to the type of knowledge (tacit vs. codified) and proximity dimension engaged. These findings contribute to the current debate in the geography of innovation and economics of knowledge literature. Keywords: region; knowledge spillovers; innovation; R&D; patent; human capital 1. Introduction Initially, the geographical proximity between firms or regions has been considered as a main transmission channel of innovation and knowledge. This idea assumes that knowledge and innovation spillovers are bounded in space and the economic entities may benefit from close location to other economic entities generating innovations [1].

This paper deals with the estimation of the impact of technology spillovers on productivity at the firm level. Panel data for American manu- facturing firms on sales, physical capital inputs, employment and R&D in- vestments are linked to R&D data by industry. The latter data are used to construct four different sets of 'indirect' R&D stocks, representing technology obtained through spillovers. The differences between two distinct kinds of spillovers are stressed. Cointegration analysis is introduced into production function estimation. Spillovers are found to have significant positive effects on productivity, although their magnitudes differ between high-tech, medium- tech and low-tech firms.

Introduction In many of the recent so-called 'endogenous growth models' (e.g. Romer, 1986, 1990 and Grossman and Helpman, 1991a), as well as the 'non- mainstream' literature on growth and technology (e.g.. Nelson and Winter, 1982), the generation of technology is the main driving force of economic growth.

A Developmental Approach to the Patent-Antitrust Interface By Thomas K. Cheng* Abstract: This Article proposes a set of guiding principles for approaching the patent-antitrust interface in developing countries. Based on the notion that antitrust doctrines need to be adjusted to reflect the local economic circumstances, this Article argues that any credible approach to the patent- antitrust interface in developing countries must incorporate development considerations. It proposes a set of guiding principles that takes into account a wide range of factors, including the need to provide innovation incentives, the need to facilitate domestic imitation, the need to protect domestic consumer welfare, and the need to safeguard access to basic necessities. With the support of a considerable body of theoretical and empirical economic literature, this Article challenges the widely held belief that patent protection is necessary for securing innovations. Rather, this Article argues that developing countries need to be skeptical about innovation-based justifications for restrictive patent exploitation practices, as many of them do not possess the capacity to take advantage of innovation incentives and can ill-afford to sacrifice consumer welfare.

Jacobs Externalities.Docx
Jacobs’ Externalities: Where We Have Been and Where We Might Go in Studying How Urbanization Externalities Affect Innovation Innovation is key to firms’ sustainable competitive advantage. When deciding where to locate the firms’ innovation activities, managers must consider the locational factors that affect firms’ innovation performance. Understanding what the most important factors are and how they come into play is important. Existing literature on agglomeration and clusters emphasizes one important factor: externalities. Externalities originate from the co-location of firms and relevant institutions. Organizations are like leaking containers whose resources constantly spill over to their immediate environment. The spillovers can be information, knowledge, talent, customers, etc. As a result, co-located firms spontaneously create common goods shared by all neighbors. The existence of externalities means when deciding where to locate their firms, managers must pay attention to their neighbors. Depending on the nature of externalities, researchers have differentiated two kinds of externalities (Gleaser et al., 1992). One is the Marshall-Arrow-Romer externalities, or the MAR externalities. The MAR externalities root its theoretical foundation in the works of Alfred Marshall (1890), Kenneth Arrow (1962), and Paul Romer (1986). In his seminal book Principles of Economics (Book IV, Chapter X), Marshall’s (1890) listed four forces that drive agglomeration: 1. Access to natural resources and transportation; 2. Labor pooling; 3. Knowledge spillover; 4. Share of middle suppliers. Aside from access to resources and transportation, all three other forces are externalities endogenously generated by lo-located firms. Marshall’s externalities are complemented later by Arrow (1962) and Romer (1986), both of whom emphasize the role of knowledge in fostering endogenous growth.

Technological Externalities and Economic Distance: a Case of the Japanese Automobile Suppliers

In order to quantify the degree of knowledge spillover or information sharing, we take the production function approach. Assuming core-periphery structure around automobile assemblies surrounded with auto-parts suppliers, we estimate plant-level production functions of the Japanese auto-parts suppliers, where productivity function depends upon the degree of information sharing measured by both geographic plant location and membership of technological cooperation associations. We take econometric issues of cross-sectional dependence of productivity and a simultaneity problem between inputs, applying methods to the standard OLS and GMM estimators. Positive technological externalities are seen in general and for independent plants, the fact which is robust to specifications of the production functions. Agglomeration effects are however rarely observed for relation-specific or cooperative plants. Some of them cost substantial negative externalities. Once a simultaneity problem is econometrically considered, instead of increasing returns, decreasing returns to scale emerge in cases of total materials.

For financial support, the first author acknowledges the National Science Council, Taiwan; and the third author acknowledges the Australian Research Council, National Science Council, Taiwan, and the Japan Society for the Promotion of Science. 1 Abstract This paper examines the impact of the three main channels of international trade on domestic innovation, namely outward direct investment (ODI), inward direct investment (IDI), and exports. The number of Triadic patents serves as a proxy for innovation. The data set contains 37 countries that are considered to be highly competitive in the world market, covering the period 1994 to 2005. The empirical results show that increased exports and outward direct investment are able to stimulate an increase in patent output. In contrast, IDI exhibits a negative relationship with domestic patents. The paper shows that the impact of IDI on domestic innovation is characterized by two forces, and the positive effects of cross-border mergers and acquisitions by foreigners is less than the negative effect of the remaining IDI. Keywords: International direct investment, Exports, Imports, Triadic Patent, Outward direct investment, Inward direct investment, R&D, negative binomial model.

Innovation work also produces innovation-labor-biased technical 1 February 2020 change (IBTC) and knowledge spillovers. Analyses use full register-based dataset of Finnish firms for the 24 March 2020 period 1994–2014 from Statistics Finland. Accepted 20 April 2020 Design/methodology/approach – Intangibles are derived from the labor costs of innovation-type occupations using linked employer-employee data. The approach is consistent with National Accounting and offered as one method in OECD (2010) and applied in statistical offices, e.g. in measuring software. The EU 7th framework Innodrive project 2008–2011 extended this method to cover R&D and OC. Findings – Methodology is implementable at firm-level and offers way to link personnel reporting to intangible assets. The OC-IBTC as well as total resources allocated to OC are relevant for productivity growth. The R&D stock is relatively higher but R&D-IBTC is smaller than OC-IBTC. Public policy should, besides technology policy, account for OC and OC-IBTC and related knowledge spillovers in the industries that are most important among the SMEs (low market-share-firms). Research limitations/implications – The data are based on remote access to Statistics Finland; the data cannot be disseminated.

Exploring the Heterogeneous Knowledge Spillover Effects from University AI Research on the Creation and Performance of AI Start-Ups
Exploring the Heterogeneous Knowledge Spillover Effects from University AI Research on the Creation and Performance of AI Start-ups Qi Wang Ke-Wei Huang National University of Singapore National University of Singapore [email protected] [email protected] Abstract This paper investigates whether and which type of AI academic research at universities can create regional knowledge spillover effects that improve the quantity and quality of AI start-ups. Using data of AI start-ups from Crunchbase.com and AI conference publications from CSRankings.com, we find that knowledge spillovers from university AI research indeed contribute to the creation and VC financing performance of local AI start-ups at the MSA level in the United States. Moreover, we find significant heterogeneous effects of knowledge spillovers in different AI subfields. The knowledge spillovers from research published in machine learning conferences, including only ICML and NIPS, have the strongest effects on the creation and performance of AI start-ups. In addition, we find evidence that impactful conferences exhibit stronger spillover effect. At the same time, surprisingly, our results show that knowledge spillovers from theoretical AI research have stronger effects on the creation of start-ups. Keywords: Artificial intelligence, Knowledge Spillovers, Entrepreneurship, Venture Capital, Information Technology 1. Introduction The last two decades have witnessed the rapid advances in artificial intelligence (AI). Recognizing the vital role of AI, more than 17 countries (e.g., the United States, Germany, and China) have implemented policies for promoting AI development at universities. This kind of policy is designed based on the assumption that AI research at universities has positive societal or economic benefits.

When an originating firm’s spillovers are recombined with complementary knowledge by recipient firms, a pool of external knowledge is formed that is inherently related to the originating firm’s knowledge base. This relevant knowledge pool contains valuable opportunities for the originator to learn vicariously from recipients’ recombinatorial activities. In a longitudinal study of 87 telecommunications equipment manufacturers, we find that a firm’s rate of innovation and the extent to which these innovations build on and integrate knowledge from the relevant knowledge pool is greater when its relevant knowledge pool is larger in size and similar to the firm’s existing knowledge base. 2 In the early 1980s, scientists at Eastman Kodak began their pioneering work on a light- emitting molecule that eventually led to Kodak’s core innovation in organic light-emitting diode (OLED) technology in 1985.
