This paper sets the contributions to this special issue in the context of a large and rapidly growing literature. It argues that although our understanding of the relationships between entrepreneurship, innovation, geography and economic growth is much clearer than in the past, there remains much that needs to be explored.

This paper starts by recognizing that despite the importance of absorptive capacity, economists in particular have made only limited use of the concept. Most theoretical and empirical studies derive from other fields of research. Thus, the first task is to compare and contrast the different approaches taken in measuring absorptive capacity. The rest of the paper then sets out an example of how typically economists have proceeded, using nationally representative CIS data to measure absorptive capacity across a 10‐year period and investigating if it remains stable in the long term. This is followed by considering how firms' characteristics vary across lower to higher levels of absorptive capacity and whether such capacity determines firms' productivity performance across both goods and service industries. Our results show that relative to other influences, absorptive capacity as measured here — net of the impact of foreign‐ownership and human capital — has a substantial influence on exporting, innovation and undertaking R&D and thus consequently firm‐level productivity. Finally, there is a discussion of why governments should consider helping firms to boost their levels of absorptive capacity. [ABSTRACT FROM AUTHOR]

Innovation research is motivated by the understanding that new technologies contribute to address societal challenges and foster welfare. Extant research in the economics of innovation has, however, adopted a narrow definition of social welfare, which focuses on economic performance and material well‐being, and that mostly disregards distributional impacts of innovation. This paper critically reviews the concept of social welfare in the economics of innovation literature, and it outlines a new research agenda that will investigate the impacts of innovation on individuals' well‐being and aggregate social welfare. The new research program has two major pillars. First, it adopts a broader notion of agents' well‐being that comprises also non‐economic factors and capabilities alongside income and material wealth. Second, it argues that welfare analyses of innovation must explicitly take into account equity and social justice in addition to efficiency and economic performance. This new research agenda opens up several novel questions for future innovation research and policy‐making, pointing to the existence of trade‐offs and dilemmas between efficiency and equity, and between short‐ and long‐run impacts of innovation on social welfare.

The empirical evidence on the economic impacts of diversity is mixed. Many studies in the literature present context‐dependent and data‐driven results which are challenging to reconcile with each other. This paper offers a systematic synthesis of the empirical findings on the economic impacts of diversity on innovation, productivity and the labour market. It presents a structured framework which takes the spatial scale of the analysis in the papers as a reference to understand the inconsistency of some previous predictions and the varying magnitudes of the diversity impact. The empirical findings reconcile more meaningfully when diversity effects are documented discretely at the regional, firm and individual levels. The paper further sets out an agenda for future research and links the findings for policy relevance. [ABSTRACT FROM AUTHOR]

The last several decades have seen increases in patenting activity worldwide, as well as growing issues related to patent quality. In response to these quality issues a recent patent literature has emerged, that investigates the behavior and incentives of patent examiners, applicants, and third parties. In this paper, we provide an overview of patent procedures, patent systems and a survey of the new economic literature on patent systems. Both theoretical and empirical papers are considered. Policy implications coming from this literature are presented. [ABSTRACT FROM AUTHOR]

Innovation policy has emerged as a new field of economic policy during the last few decades. This paper explores the rationales for national innovation policies, as laid out in the existing literature on the subject, and considers what the lessons and challenges for theory and practice in this area are. Innovation policy attempts to influence innovation activity, often with the purpose of increasing economic growth. But it can also have more specific aims such as preventing unwarranted climate change, improving national health, and so on. The increasing attention given to innovation policy at the national level from the 1990s onwards went hand in hand with the development of a new, systemic understanding of innovation, which in a better way than before accounted for the 'stylised facts' of innovation activity as identified by empirical work. The system approach, as the paper shows, came to have a significant influence on the subsequent policy discourse. Drawing on recent advances in innovation-systems theory, a synthetic framework for the analysis of innovation policy is developed and used to highlight issues of particular relevance for the conduct of innovation policy and future scholarly work in this area.

Entrepreneurs have started relying on crowdfunding to fund their investments. This paper surveys the literature linking crowdfunding with innovation in entrepreneurial firms. Two distinct areas are discussed. First, crowdfunding has the potential to foster innovation by offering new sources of capital to innovation‐driven firms and thereby reduce the funding gap for innovative startups. Second, crowdfunding offers a way for the crowd to participate in the innovation process by providing feedback to the entrepreneur. This feedback can take various forms, including providing ideas on the development of the product during and after the campaign (in the spirit of crowdsourcing), and providing valuable information on the future demand for the new product.

Without the confidence that patent rights can be enforced quickly and efficiently, when needed, the patent system will not stimulate innovation. For this reason, governments, academics, international institutions and the private sector have poured significant resources into gathering and analysing statistics on patent enforcement over the last two decades. This paper reviews these studies and finds that while infringement is relatively common, much enforcement occurs informally and less than 1-2% of patents incur litigation. New strategic uses of the enforcement system, especially by nonpracticing entities, are the major emerging enforcement issue, especially in the United States. While the old problem of litigation costs attracts the lion's share of empirical attention, it has produced remarkably few solutions to date. [ABSTRACT FROM AUTHOR]

The traditional economics of innovation, inspired by Schumpeter and more recent advances on his work, seem unable to explain why firms with similar external conditions may show greatly different performance in innovation. Contrastingly, the literature on corporate governance provides some useful insights for understanding corporate innovation activity, to the extent that such literature examines the economic effects of different modes of coordination between firm members. The process through which individuals integrate their human and physical resources within the firm is central to the dynamics of corporate innovation. This paper provides the first survey of the literature on this issue. We start by discussing how various theoretical approaches to the analysis of the firm deal with technological innovation. We then describe three main channels - corporate ownership, corporate finance and labour - through which a system of corporate governance shapes a firm's innovation activity. Finally, we examine the relationship between country-level institutional settings, national patterns of corporate governance and the aggregate innovation activity of corporations. We conclude by suggesting that future research should focus more deeply on the interrelation between the various dimensions of corporate governance and on their joint effect on firm innovation.

This paper presents a critical review of evolutionary and new growth theories. The purpose is to discuss the often-made claim that the two approaches, both inspired by Schumpeter's seminal work, are becoming more and more similar in terms of the sources and mechanisms of the growth process on which they focus. According to this argument, some kind of theoretical convergence between the two paradigms is taking place. Differently from previous surveys of the field, this paper compares evolutionary and new growth theories by focusing on their major theoretical foundations. The discussion leads to the conclusion that the two approaches greatly differ with respect to all of their main theoretical building blocks, and that no convergence between the two paradigms is therefore taking place. This finding should be welcomed by both evolutionary and new growth scholars, because it is the process of interaction and the fruitful exchange of ideas between different approaches that lead to advances in growth theory, not their convergence to a common paradigm.

Innovation can occur at the national level under a wide range of settings. However, the leading innovative countries internationally have several common traits, including economic, financial and political stability, which are reflected in various measures of country risk. The purpose of the paper is to examine, for the first time, the relationship between the economic, financial and political country risk ratings, on the one hand, and innovation, as measured by a country's registered patents, on the other. The relationships between various monthly country risk ratings and registered patents are analyzed for the leading 12 foreign patenting countries in the USA from 1975 to 1997. The empirical results show that economic, financial and political risk ratings have a considerable impact on the innovative activities of the 12 countries. Total US patent applications are also influential in inducing innovation in the 12 countries. Such issues have not previously been addressed in the literature on country risk and innovation.

Following the development of knowledge economies, there has been a rapid expansion of economic analysis of knowledge, both in the context of technological knowledge in particular and decision theory in general. This paper surveys this literature by identifying the main themes and contributions, and outlines the future prospects of the discipline. The wide scope of knowledge-related questions in terms of applicability and alternative approaches has led to the fragmentation of research. Nonetheless, one can identify an enduring quest for analyzing various aspects of the generation, dissemination and use of knowledge in the economy. [ABSTRACT FROM AUTHOR]

Innovation has been increasingly recognized as a critical force in national economic growth not only in developed countries, but also in emerging countries such as China and India. This paper provides a critical review of the literature related to China's innovation capability. First, I evaluate the current status of China's innovation capability as measured not only by the level of human capital and output of academic research but also by patents, products, and services that directly benefit economic growth. I then review the development pathway of China's national innovation system since the economic reforms, including policies, the role of the government, and the engagement of different actors in the national innovation system. Following that, I examine theories and empirical evidence that help to explain the evolution of China's innovation capability. Finally, using China's experience, I analyze the relationship between innovation capability and economic development and highlight how the uneven spatial distribution of innovation capability may affect China's regional economic development.

Both theoretical and conceptual understanding of innovation has developed significantly since the early 1980s. More noticeable, however, are the major changes that have been experienced in empirically-oriented innovation research as a result of the introduction of firm level innovation surveys. Collecting innovation related data via firm based surveys has now become a common practice for many countries for example, Canada, United States, Malaysia, Taiwan, Australia, New Zealand as well as almost all EU countries. These survey-lead approaches have transformed our understanding of the nature and determinants of innovation and also increased our understanding of the role played by innovation in growth. At the same time, the surveys themselves have also been adapted as our conceptual understanding of innovation has increased. As such, the balance of innovation-related research has shifted from a theoretical to a primarily empiricist-lead agenda, and increasingly combined both quantitative and qualitative approaches. The objective of this paper is examine how our understanding of innovation has evolved over the last few decades, to identify the major theoretical and empirical influences on our understanding, and to assess the role which innovation surveys have played in this evolution.

This paper emphasizes the role of labour demand as a determinant of human capital formation. After a section in which the alternative conceptions on the functioning of labour markets are presented and different ways of measuring human capital are compared, an applied analysis is carried out in which we provide a labour-demand-oriented measure of human capital, as defined by the amount of specific skills firms generate through work-based training (WBT) activities. By merging three rich firm-level datasets, we estimate the impact of a set of variables supposed to affect both the propensity to invest in WBT and the intensity of training within the Italian manufacturing industry over the period 2001–2005. Special attention is devoted to the variables characterizing within-firm organization of knowledge, organizational change and the formation of competence pipelines: among them, innovation, internationalization commitment, out-sourcing and new hirings. The estimates show that the effect of innovation on WBT is higher when the introduction of new technologies is supported by organizational innovations. When looking at the nature of WBT, we investigate the different determinants of the firms' propensity to provide both in-house and outside training. We measure training intensity in terms, respectively, of the number of provided training activities, private and total training costs and share of trainees. [ABSTRACT FROM AUTHOR]

Abstract: The effect of technological innovation on employment is of major concern for workers and their unions, policy makers and academic researchers. We meta‐analyse 570 estimates from 35 primary studies that estimate a derived labour demand model. We contribute to existing attempts at evidence synthesis by addressing the risks of selection bias and that of data dependence in observational studies. Our findings indicate that: (i) hierarchical meta‐regression models are sufficiently versatile for addressing both selection bias and data dependence in observational data; (ii) innovation's effect on employment is positive but small and highly heterogeneous; (iii) only a small part of residual heterogeneity is explained by moderating factors; (iv) selection bias tends to reflect preference for upholding prevalent hypotheses on the employment effects of process and product innovations; (v) country‐specific effect‐size estimates are related to labour market and product market regulation in six OECD countries in a U‐shaped fashion; and (vi) OLS estimates reflect upward bias whereas those based on time‐differenced or within estimators reflect a downward bias. Our findings point out to a range of data quality and modelling issues that should be addressed in future research. [ABSTRACT FROM AUTHOR]

In this study, we review the literature on the creation and diffusion of innovation in the private sectors (industry and services) in developing countries. In particular, we collect evidence on what are the barriers to innovation creation and diffusion and the channels of innovation diffusion to and within developing countries. We find that innovation in developing countries is about creation or adoption of new ideas and technologies; but the capacity for innovation is embedded in and constituted by dynamics between geographical, socio-economic, political and legal subsystems. We contextualize the findings from the review in the current theoretical framework of diffusion of innovations, and we emphasize how the institutional context typical of developing countries impacts the diffusion itself.

Both theoretical and empirical work reports contingent and conflicting findings on how intellectual property (IP) protection affects related outcomes such as innovation, technology diffusion, productivity, or growth. To establish where the balance of the evidence lies, we conduct a multi‐outcome meta‐regression analysis to synthesize findings form 91 primary studies that report 1626 effect‐size estimates for one or more outcomes. Controlling for unobserved heterogeneity and selection bias only, we find that the effect on innovation, technology diffusion, productivity, and economic growth is statistically or practically insignificant. The effect remains insignificant when we control for observed sources of heterogeneity and estimate meta‐effects based on different scenarios for "best‐practice" research. Our work contributes to the existing research effort by extending the application of the multi‐outcome meta‐regression analysis into evidence synthesis in economics. It also provides verifiable/replicable evidence indicating that the sanguine claims about the economic benefits of IP protection voiced in some legal studies and the advocacy literature are misleading.

This survey examines the empirical literature on the relationship between public R&D subsidies and private R&D investment over the past five decades. The survey reveals a considerable heterogeneity of empirical results that cannot be explained fully by methodological issues. We aim to provide further explanations of the possible causes of that heterogeneity. In particular, we emphasise a set of issues that, in our view, are critical to understanding the potential effect of public R&D subsidies on private R&D spending. Special attention is paid to the dynamic aspects and composition of firm R&D, the constraints faced by the firm (such as financial constraints), and the amount and source of public subsidies. None of these issues have been investigated in depth. We formulate a set of research assumptions to guide future empirical research in this field. [ABSTRACT FROM AUTHOR]

The so‐called "new growth theory" is characterized by the now Nobel Prize winning insight that ideas are a nonrival input to and output from endogenous investment in innovation. Nonrivalry implies increasing returns to scale, but this also unintentionally creates an empirically disputed scale effect that a growing population implies an ever‐increasing growth rate. Empirical evidence supports fully‐endogenous growth without scale effects, but theoretical issues sustain the decades‐long dispute over exactly how to negate the scale effect. This article surveys theoretical approaches to resolving the scale effect and shows how four generations of endogenous growth theory are defined by the maturing of modeling techniques for constraining increasing returns. The synthesis suggests that the dispute over scale effects is really a narrative about how the powerful application of increasing returns has followed a standard theoretical development pattern. This implies that a fourth generation is now emerging that negates the scale effect while retaining fully‐endogenous growth without relying on assumptions of linearity. Instead, the market response to excessive increasing returns to innovation constrains explosive growth by expanding the market, rather than by a linear assumption. This latest class of endogenous growth models may be the final chapter to resolving the long‐running dispute. [ABSTRACT FROM AUTHOR]

This study summarizes the main conclusions from a systematic review of the empirical literature regarding the impact on firms of the use of knowledge external sources (universities, research institutes and knowledge intensive business services). With the aim to organize the literature, we classify the different works according to the research question addressed: (i) which firms use knowledge external sources?; (ii) Do firms using knowledge external sources achieve better results?; And (iii) which firms benefit the most from using knowledge external sources? Stylized facts are that larger, more R&D intensive and high tech firms are more likely to use knowledge external sources and that use of knowledge external sources is associated to firms higher technical results. Less attention has been paid to the third question and evidence is not conclusive. Several recommendations for future research emerge. First, to take in greater consideration methodological issues so that potential biases in the results caused by sample selection and endogeneity are handled properly. Second, to pay more attention to heterogeneous outcomes. Third, to use continuous indicators of depth and breadth of links allowing for non-linear relationships and fourth, to extend evidence for developing countries and service industries.

Patent litigation has become an increasingly important consideration in business strategy. Damage awards in patent litigation are supposed to compensate the patent owner for economic harm created by infringement and are therefore important for protecting returns to innovation. We analyze the effects that a recent court decision in the United States, called Grain Processing, has had on the incentives of potential infringers to infringe and innovators to innovate. We find that Grain Processing has decreased the expected value of damages awards in patent cases by conferring a ‘free option’ on infringers. Grain Processing also concluded that the patent owner in the case did not suffer lost profits due to the infringement because the infringer would have adopted an (inferior) non-infringing technology had it not infringed. We demonstrate that this conclusion is inconsistent with standard economic models. [ABSTRACT FROM AUTHOR]
