Innovation

Summary

Innovation is the practical implementation of ideas that result in the introduction of new goods or services or improvement in offering goods or services. ISO TC 279 in the standard ISO 56000:2020 defines innovation as "a new or changed entity realizing or redistributing value". Others have different definitions; a common element in the definitions is a focus on newness, improvement, and spread of ideas or technologies. Innovation often takes place through the development of more-effective products, processes, services, technologies, art works or business models that innovators make available to markets, governments and society. Innovation is related to, but not the same as, invention: innovation is more apt to involve the practical implementation of an invention (i.e. new / improved ability) to make a meaningful impact in a market or society, and not all innovations require a new invention. Technical innovation often manifests itself via the engineering process when the problem b

As an important policy instrument for guiding innovation, the patent system involves a long-standing tension between creating economic rewards for the original innovators and stifling subsequent R&D activities. The availability of new data allows us to provide unique sights into understanding how effective patents are in providing incentives for innovation and how firms' disclosure of proprietary assets affects the dissemination of knowledge. On the other hand, innovation per se is the fruit of human intellect. The knowledge workforce is, therefore, a crucial component of a country's innovative capacity. The persistent gap in the participation in innovative activities between men and women reflects a misallocation of talented human capital and leaves opportunities for policy implementation. This dissertation ties the questions mentioned above and presents novel evidence on the incentives, diffusion, and disparity in innovative activities. The first essay (chapter 2), in collaboration with Gaétan de Rassenfosse, provides empirical evidence on the real effect of patent expiration on monopoly prices and explores how this effect varies with product market competition. We compile a novel dataset that links patents to consumer products and retail prices for these products from Amazon.com. We find that patent expiration leads to a 7--8 percent drop in product prices. This effect is heterogeneous by patent type and importance and starts one year in advance. We also find a more substantial decline in prices in product markets where competition is intense, consistent with evidence from the pharmaceutical industry. We argue that incumbent innovators lower prices preemptively in the face of generic competition. The second essay (chapter 3), in collaboration with Gaétan de Rassenfosse, studies how firms' disclosure of innovative assets affects the diffusion of inventions. We focus the empirical setting on firms' provision of constructive notice through virtual patent marking (VPM) and exploit patent-level variation in the marking dates. With data collected on marked patents from the VPM web documents of 16 firms, we find an overall effect of VPM is small. However, conditional firms' strong reliance on patents as an appropriability regime, our findings suggest that while VPM induces firms to build subsequent internal inventions on the ones that are commercially valuable, it fends off diffusion to external firms and reduces similarity between inventions. Last but not least, in the third essay (chapter 4), collaborated with Mary Kaltenberg, we explore the role of family policies in closing the innovation gender gap. By matching inventor data to web-scraped inventor age information, we exploit the staggered passage of maternity leave policies across the U.S. and evaluate its impact on the retention and productivity of female inventors. Our findings suggest that maternity leave policy supports women of reproductive ages stay longer in patenting but has little impact on their productivity.

IT Investment and its impacts

Shameem Hasan

This thesis empirically explored the impacts of IT investment on three different scenarios under the common denominator / threads of IT investments. It comprises three different essays on the impacts of IT investments. IT investments and its impact on many aspects of the firms are well known - like performance / productivity, output, market value etc. But I looked into areas that were not explored before and examined events that didnât take place after the advent and integration of Information Technology â like the past financial crisis. The main contribution of my dissertation is to examine how IT investments helps in the debt market, how it helps firms fare comparatively better during crisis period and how CEO characteristics influence the well-established existing link between IT investment and Innovation intensity. The first essay examines the effect of IT investment on the cost of bank loan for firms. We argue that IT affects the decision of banks through three mechanisms: wealth effect, risk effect, and information effect. First, IT investment serves as a signal for higher future revenue and lower operational costs, thus greater future cash flows. Second, on one hand, IT may be able to reduce the risk of being locked out to competition or adverse situations; on the other hand, IT investment itself can bring risk to business. Last, the use of IT can lead to better information quality and thus reduce the information asymmetry between firms and banks. Using a sample of 270 firms between the year of 1991 and 2006, we find that IT investment is associated with lower interest rate from banks. More important, we find the strength of this relationship is contingent upon the role of IT in the industry and time period. In my second essay, the goal was to investigate whether IT investment contributed to better or worse performance during the financial crisis of 2007-2009. We took the available data for U.S. public companies (the final sample comprises 570 companies) and traced IT investments made in the years prior to the crisis period, we checked the impact of IT investments on the annual stock returns and relative changes in return (as well as for book values). After controlling for relevant risk and other independent variables during the 2007-2009 periods, we found evidence that indicates that although most of the firms suffered during the crisis period, expenditure in IT was significantly associated with relatively better performance for sample firms during the crisis period. The third essay brings in the role of CEO to examine whether CEOâs characteristics affects the already established link between IT investments and Innovation activities. We constructed data from multiple sources; we also developed empirical model to test our hypothesis and ran a series of regression tests. We find that CEOâs managerial ability and risk-taking incentive (determined by compensation scheme) are complements for IT investment. Thus for CEOs with lower ability and/or lower risk-taking incentive, firms can still achieve higher innovation efficiency by increasing expenditure in IT. On the other hand, CEOâs ownership of the firm substitutes the link. CEO with larger ownership enhances firmâs innovation efficiency by due diligence, but not necessarily through the channel of IT investment. In together, this paper shows that CEO is an important and significant factor in the conversion of IT investment to innovation efficiency.

Innovation dynamics in the medical device sector

Monica Coffano

This thesis aims to provide new insights into the evolution of the medical device sector (MedTech). After the analysis of the history of the sector, I examine the key points that in the past 60 years, have led the industry to grow so impressively, and I proceed to an analysis of the actual situation. The scope of the thesis is to understand if what has stimulated the success of the sector at the beginning is still important, and if the introduction of new elements has positively changed the evolution of the sector. The thesis is composed of three works. The first work (chapter 2) is developed in collaboration with Dominique Foray and Michele Pezzoni. I analyze how the network structure of inventors in the Swiss regions can influence regional innovation performance. I aim to contribute to the existing literature related to the debate on the importance of inventors' collocation for the creation of innovation. I claim that an increased degree centrality of MedTech inventors in the regional technological community is positively associated with the number of MedTech patent applications in the focal region. Moreover, the presence of MedTech inventors in the principal component of the regional technological community is positively associated with the number of MedTech patent applications in the region. However, local connections are not enough to promote innovation. In fact, the results show that intense cross-regional linkages of MedTech inventors increase the number of MedTech patent applications in the region. Thus, it is not only important that an inventor be well connected within her region, but also that she be exposed to external knowledge in order to increase her possibility of achieving high performance in MedTech within that region. Finally, I want also to understand how MedTech is open to other technological domains. I find that the average degree centrality and cross-regional linkages of academic inventors and inventors specialized in technologies complementary to MedTech affect regional innovation outcomes. The second work (chapter 3) is developed in collaboration with Dominique Foray. I aim to study the impact of external technologies on the MedTech sector. I start analyzing the literature of knowledge spillovers, and I do a comprehensive review of the extant measures of knowledge spillovers. I argue that the classical measures based on patent backward citations should be carefully interpreted. The reason as to why this type of index needs a prudent interpretation is linked to the characteristics of different technologies in terms of the speed at which other sectors are capable of understanding, absorbing and using them. Therefore, I propose a new formulation of the classical measure of backward citations. The third work (chapter 4) is developed in collaboration with Fabiana Visentin. I aim to understand the effects of the MedTech regulation that entered into force in Europe in 1993. I argue that the regulation has two effects. The first effect is related to the level of radicalness in the innovation. I claim that after the introduction of the regulation, and consequently with the tightening of the requirements to fulfill, firms became more careful and less motivated to propose radical innovations. At the same time, standardization of the requirements over the European countries gives to firms the possibility of widening their market.
