ENDOGENOUS HUMAN CAPITAL INVESTMENT AND THE INTERACTION OF FRONTIER AND ADOPTIVE KNOWLEDGE ON GROWTH AND WAGE INEQUALITY

A three-sector, overlapping-generations growth model endogenizes the opportunity cost of human capital formation and the relative skill requirements of invention, innovation, and adoption of general-purpose technologies. As a result, the relative wage of skilled workers is a function of the endogenous ratio of total-to-adoptive knowledge (where the difference in knowledge stocks is frontier knowledge). Comparative statics are examined for the model's seven parameters. Simulations (representing a transition with phases to a more complex level of economic development) are presented for simultaneous exogenous shocks capable of matching (i) observed inverse movements of the relative wage and the detrended relative supply in the USA, (ii) the sharp slowing and recovering US multifactor productivity growth data since the 1970s, and (iii) a reconciliation of data used to support or deny skill-biased technological change as a major force driving up the relative wage since 1980.     

MIGRATION AND AGGLOMERATION WITH KNOWLEDGE SPILLOVERS*

In this paper, a Grossman–Helpman–Romer‐type endogenous growth model is developed that incorporates two regions and mobile workers. While the linkage between final goods firms and intermediate goods firms is strong, the linkage between innovation activities and manufacturing activities is weak in our paper. It is possible for the economy to reach either full agglomeration, partial agglomeration, or segmented agglomeration. We find that mobile workers acquire the highest welfare under full agglomeration. However, under segmented agglomeration, the welfare of skilled workers is not necessarily the lowest.     

THEY DON'T INVENT THEM LIKE THEY USED TO: AN EXAMINATION OF ENERGY PATENT CITATIONS OVER TIME

This article uses patent citation data to study flows of knowledge across time and across institutions in the field of energy research. Popp [2002, Induced Innovation and Energy Prices. American Economic Review, 92(1), 160–180.] finds that the level of energy-saving research and development (R&D) depends not only on energy prices, but also on the quality of the accumulated knowledge available to inventors. Patent citations are used to represent this quality. This article explores the pattern of citations in these fields more carefully. Evidence for diminishing returns to research inputs, both across time and within a given year is found. To check whether government R&D can help alleviate potential diminishing returns, special attention is paid to citations to government patents. The government patents filed in or after 1981 are more likely to be cited. More importantly, descendants of these government patents are 30% more likely to be cited by subsequent patents. Earlier government research was more applied in nature and is not cited more frequently.     

INNOVATION PLATFORMS AND THE GOVERNANCE OF KNOWLEDGE: EVIDENCE FROM ITALY AND THE UK

Innovation is a collective process that entails the coordination of distributed knowledge across diverse organizations. Technology infrastructures provide innovation systems with governance mechanisms to create and sustain complementarities across otherwise dispersed competences. The paper presents innovation platforms as a specific case of technology infrastructure. Operating strategically at the interface between the public and the private sectors, platforms enable capacity- and capability-building for individuals, teams and organizations. Illustrative evidence on innovation platforms in the United Kingdom and Italy confirms the importance of institutional responsiveness to stimulate variety and ensure coordination in the context of collective innovation processes.     

KNOWLEDGE AND INNOVATION: PROMOTING A SYSTEM APPROACH OF INNOVATION PROCESSES

Abstract

This contribution intends to clarify for the current discussion about knowledge and its importance within economic systems. It relies on the complementary character of the economics of knowledge of Marshall and Hayek. One of them is useful to discuss opportunities and limits of the so-called resource-based theory of the firm in order to deal with the relationship between the governance of knowledge and firms' innovative behaviours; the other is useful to insist on the importance of knowledge channelled by and within market dynamics. As a consequence, their combination allows one to pave better grounds to current knowledge economic importance by exploring in-depth characteristics of knowledge, expressing the need to deal with the governance of technological knowledge, and promoting the localized and distributed characters of firms' innovative behaviours. This finally leads to promote an innovation-system approach based on that localized character of innovative behaviours of firms in order to depict proper use made by firms in matters of knowledge generation, use, dissemination, and trade.     

THE GOVERNANCE OF KNOWLEDGE COMPOSITENESS AND TECHNOLOGICAL PERFORMANCE: THE CASE OF THE AUTOMOTIVE INDUSTRY IN EUROPE

Abstract

Knowledge compositeness measures the variety of scientific disciplines that it is necessary to command in order to generate new technological knowledge. The paper investigates the relations between the knowledge compositeness of the flow of patents delivered to the main European automobile companies and the evolution of their technological and product market shares. Compositeness confirms to be an important characteristic of private knowledge: its governance exerts strong and positive effects on the technological and competitive advantage of firms. Knowledge compositeness has strong effects on the mechanisms of knowledge governance and management of technology. Appropriate measures of knowledge compositeness make it possible to qualify the quantitative measures of the technological competence of firms based upon patents counts.     

ABSORPTIVE CAPACITY AND INNOVATION IN THE KNOWLEDGE INTENSIVE BUSINESS SERVICE SECTOR

Innovative activity is performed to a considerable extent in the service sector, namely within the so-called knowledge intensive business services (KIBS). Particularly emphasizing the role of absorptive capacity, we analyze possible determinants of incremental and radical firm innovation using firm micro data from the KIBS Foundation Survey. The results show that access to knowledge through networking and cooperation is of utmost importance for innovative activity in the KIBS sector. Access to knowledge from universities and research institutions is particularly important for radical innovation, notwithstanding the degree of formality of cooperation. In contrast, access to knowledge from clients or suppliers only has a significant impact on the probability to innovate if the cooperation with these partners is based on formal cooperation via joint projects or formal cooperation contracts. Furthermore, we find empirical evidence for a positive correlation between KIBS firms and clients from the manufacturing sector: these stimulate in particular incremental, but also radical innovation.     

THE CHANGING GOVERNANCE OF KNOWLEDGE IN AVIONICS

Abstract

Taking in hand the two sides (i.e. cognitive and risk-bearing) of authority in design and production in complex tasks, this paper aims to give a first look at shifts in the locus of authority in the aviation electronics—or avionics—industry. Relying on patent and joint ventures data, we attempt to trace the evolution of problem-solving ‘authority’ over the evolution of the industry, using an empirical approach which can then be used to explore similar trends in other industries. We find that while it is still too early to say whether we are observing a wholesale shift of ‘authority’ from aircraft makers to avionics producers, it is clear that the leading avionics producers are challenging their clients in taking the role of systems integrators. We can speculate that we may be observing the beginning of a ‘market for technology’. At the very least, we are observing an increasing distribution of both problem-solving authority and risk in this industry.

Knowledge flows and innovation capability: The patenting trajectory of Taiwan's thin film transistor-liquid crystal display industry

This paper uses USPTO's patent data to present and analyse knowledge flows and innovation capability within and across Taiwan's top five major players in the thin film transistor-liquid crystal display (TFT-LCD) industry. Based on the empirical results, the study shows that latecomers, such as Taiwan, to the TFT-LCD industry have internalised external knowledge from the US and particularly from Japan on specific core technologies, while the knowledge relationship between source and recipient is un-intimated. One important finding of this study is that Taiwan's top five TFT-LCD manufacturers possess different knowledge sources and technology focuses. This specialised capability is most likely the cause for their positions in the market (i.e. market share). Each player has unique patenting protocol, in which the coded knowledge (i.e. patenting rate) does not act as a major indicator of innovation performance in Taiwan's TFT-LCD industry. Remarkably, the public research institute does not show its essential impact on TFT-LCD industry as it once was in most East Asian latecomer literature. This study thus provides some useful managerial implications for latecomer firms to facilitate knowledge internalisation and build endogenous innovative capabilities.     

TECHNOLOGY SPECIALIZATION AND THE MAGNITUDE AND QUALITY OF EXPORTS

Abstract

This paper examines how technology specialization, measured by citation-weighed patents, affects trade flows. The paper analyzes the relationship between (i) technology specialization and export specialization across regions and (ii) the technology specialization of origin and destination and the quality of export flows. We find that the export specialization of regions corresponds to their technology specialization. Regions with higher technology specialization export products of higher quality, as indicated by higher prices. Moreover, export flows to destination countries with a high technology specialization consist of products of higher quality in the specific technology. The results are consistent with knowledge and technology being important for export performance and with regions with higher specialization in a technology being better equipped to produce high-quality products. They are also consistent with destinations of higher technology specialization, having a more pronounced demand for products of higher quality in the same technology.     

THE REVOLUTION WITHIN: ICT AND THE SHIFTING KNOWLEDGE BASE OF THE WORLD'S LARGEST COMPANIES

This empirical article analyses the importance of information and communications technologies (ICT) in the technological diversification trend among the world's largest manufacturing firms during the 1980s and 1990s. The objective of the research is twofold: first, to emphasise the emerging differences among technologies when companies from different industries patent outside their traditional technological capabilities; secondly, to investigate whether the tendency among large companies from all industries to patent in ICT is distinctive when compared with the tendency to patent in other technologies. We find that technological diversification in large companies has clearly occurred in ICTs. Non-ICT specialist industries increasingly develop, rather than just utilise, the cluster of ICT-related technologies. We conclude that the development of corporate capabilities in the key technologies of the emerging ICT paradigm is more widespread than previously emphasised in the literature. One implication of this observation is that technological diversification and the information revolution may be related phenomena.     

Externalities of investment, education and economic growth

We present a growth model in which investment in physical capital shows positive externalities which build up knowledge capital. A prerequisite for these spillovers to take place is that a country devotes time to education. Externalities associated with investment need education to raise the stock of knowledge capital. Analysing the competitive economy we demonstrate that the model may explain why some low-income countries show convergence whereas others do not. Furthermore, we demonstrate that in the social optimum the level of investment is always higher than in the competitive economy whereas the time spent for education may be lower or higher. We also show how the competitive economy may replicate the social optimum for an appropriate choice of a lump-sum tax and an investment subsidy. Empirical evidence is provided in order to demonstrate the plausibility of our model.     

A Schumpeterian model of endogenous innovation and growth

A disequilibrium model of endogenous innovation and growth is presented. The behaviour of the agents is supposed to be governed by routines, not by maximization. The entrepreneurs are assumed to invest a fraction of their operating profits in real capital accumulation, and another fraction in R&D. The latter leads to an increase in labour productivity via a R&D production function. In this Schumpeterian model, not only the R&D processes of innovations are considered, but the diffusion processes as well. As in Schumpeter's theory of economic development the economic impact of technical change is considered a disequilibrium phenomenon. Thus, in a capitalist economy characterized by ongoing diffusion processes of innovations, time averages are more important than steady state values even in a long run perspective.

The Manhattan Metaphor

Fixed operating costs draw a sharp distinction between endogenous growth based on horizontal and vertical innovation: a larger number of product lines puts pressure on an economy’s resources; greater productivity of existing product lines does not. Consequently, the only plausible engine of endogenous growth is vertical innovation whereby progress along the quality or cost ladder does not require the replication of fixed costs. Is, then, product variety expansion irrelevant? No. The two dimensions of technology are complementary in that using one and the other produces a more comprehensive theory of economic growth. The vertical dimension allows endogenous growth unconstrained by endowments, the horizontal provides the mechanism that translates changes in aggregate variables into changes in product-level variables, which ultimately drive incentives to push the technological frontier in the vertical dimension. We show that the potential for exponential growth due to an externality that makes entry costs fall linearly with the number of products, combined with the limited carrying capacity of the system due to fixed operating costs, yields logistic dynamics for the number of products. This desirable property allows us to provide a closed-form solution for the model’s transition path and thereby derive analytically the welfare effects of changes in parameters and policy variables. Our Manhattan Metaphor illustrates conceptually why we obtain this mathematical representation when we simply add fixed operating costs to the standard modeling of variety expansion.     

吸收能力与企业创新绩效

KNOWLEDGE ACCUMULATION, AND PRODUCTIVITY: EVIDENCE FROM PLANT-LEVEL DATA FOR IRELAND

This paper investigates whether knowledge accumulating activities, such as exporting, R&D, or worker training, can enhance plants' productivity. To this end, we use plant‐level panel data for Irish manufacturing. Our results importantly indicate that productivity enhancing effects of these factors are found only for domestic firms, but not for foreign multinationals located in Ireland. We postulate a number of potential reasons inherent to multinational activity possibly driving this result.     

CONSUMPTION AND LEISURE EXTERNALITIES, ECONOMIC GROWTH AND EQUILIBRIUM EFFICIENCY

This paper analyzes the effects of consumption and leisure externalities on growth and welfare in a two‐sector endogenous growth model with human capital accumulation. Both types of externalities are shown to affect the long‐run equilibrium and optimal growth rates in a rather different way. The relationship between the steady state of the market and the centrally planned economy is also analyzed. The optimal growth path can be decentralized by resorting to consumption or labor income taxation, whereas capital income should be untaxed. Numerical simulations suggest that growth and welfare effects of mild consumption and leisure externalities may be quantitatively important.
