Resources: The effect of Top Management team characteristics and outside influences on the knowledge management of small entrepreneurial firms

Bewaji, Tolulope January 2009 (has links)
This study examines small entrepreneurial firms and factors that influence their level of knowledge management and knowledge creation. The dissertation investigates the effect of top management team as a resource in small entrepreneurial firms. Stepping outside of the internal resources of a firm, this paper also delves into the effect of outside sources of capital and knowledge of firm knowledge creation. The paper enriches research on the factors that increase knowledge creation and knowledge management of small entrepreneurial firms. First, in response to evidence that Top Management Team (TMT) characteristics affect performance of high technology firms, this examined TMT average age, education and founder presence effect on the research and development (R&D) intensity, in a cross-sectional sample of software and pharmaceutical firms, with IPOs between the years 2002 and 2004. Average education is positively associated with R&D intensity. The interaction of TMT education and TMT average age negatively affects R&D intensity. TMT education in founders is positively associated with R&D intensity. The first set of results enriches extant research on TMT characteristics’ effect on R&D intensity, which ultimately affects firm performance. Continuing, extant research posits that the research and development (R&D) intensity of firms is highly correlated with knowledge creation as measured by patent citation. This paper argues that there are unexplained variables that moderate the effectiveness of research and development knowledge creation. Using the resource-based view, the top management team (TMT), is examined as an intangible asset. Hypotheses are developed on how high-technology firms’ creation of knowledge, operationalized as their patent citations output, is affected by the TMT characteristics of average age, education level, education background, founder presence, and TMT industry experience. The findings show that TMT education background and TMT industry experience are significant influences on firm patent citation. When controlling for the TMT variables, R&D intensity was not significantly related to patent citation. Finally, research on research and development intensity demonstrates a strong association with patents. At the same time, there is an unexplained gap in the move from research and development to patents in explaining innovation. Prior research assumes that internal resources are preeminent, ignoring the role of external factors. This paper reviews outside resources to assess their effect on patent citation and patent rates. It was found that partnerships with universities and firm geographic location improve innovative activity, whilst grants from the government and partnerships with large firms are not significantly associated with innovative activity. The Board of directors (BOD) has no significant impact on innovative activity. In terms of interaction effect, BOD has a negative interaction effect with geographic clusters. This paper enriches research on the outside resources that increase innovative activity. / Business Administration

Essays in Entrepreneurship and Finance

Ratigan, R David January 2019 (has links)
In this dissertation, I study three economic issues in the field of entrepreneurship and a fourth that looks at the network structure of financial markets. Chapter 1, titled "Patenting and Nascent Firm Performance", examines how patents interact with nascent firm outcomes. The primary motivation follows a puzzle present in the data and discussed in the literature. Patents are prized possessions for business owners but the value that they confer is dubious. In this sample, patenting firms have no better survival rates and have significantly worse profit outcomes. A Oaxaca decomposition demonstrates the reason for this lies with patents' attraction of equity financing. The burden of the equity relationship proves to be a strain on the young firms. Chapter 2, titled "Signal vs Appropriation Value in Patenting" provides insight into the causal connection between patents and equity financing. This chapter also weighs in on the source of the equity firms' attraction to patents. Controlling for unobservable influences via fixed effects regression, the value measured by the coefficient on patent, demonstrates the appropriative value of the patent, rather than the signal value. Further examination reveals that equity firms are very sensitive to the legal status of the firm, eschewing general partnerships. Chapter 3, titled "Peer Effects in Entrepreneurship", studies gender differences in firm financing as a function of response to peers. This research borrows from the social interaction modeling pioneered by Charles Manski by adopting methods to include peer variables. The main finding is that males are positively and significantly affected by peer financing levels but females are not. This result is robust to industry, experience, credit risk, and other financing sources. Chapter 4, "Network Analysis of the S\&P 500", examines the financial market as a network. The literature takes two approaches to performing this analysis but no study has compared the two approaches. This chapter is the first study to compare them and provide insight as to which provides the more descriptive model. The threshold correlation approach provides much more useful results for any kind of analysis involving market connectedness and shock transition dynamics. / Economics

Essays on Corporate Innovation

Weathers, Jamie January 2016 (has links)
This dissertation empirically explores the facets of corporate innovation in the firm and the ultimate effects on firm value. In the first chapter I identify firm innovation as a new channel by which employee treatment affects firm value. Growth and innovation incentive theories support positive effects of “good” employee treatment on innovation. Alternatively, entrenchment theory suggests such treatment will lead to complacency and shirking, hence deterring innovation. These opposing views merit investigation since in the “new economy”, human capital is increasingly essential to firm value and the growth and success of a firm has become more reliant on corporate innovation. Using the KLD Research & Analytics, Inc. SOCRATES database and newly acquired patent/citation data, I find an overall significant positive relationship between positive employee treatment and innovation quantity (patents) and quality (citations per patent); both measures are significantly correlated to firm value in the literature. Furthermore, I find that favorable employee treatment improves innovation focus – innovation projects more related to firms’ core business. These findings, robust to an alternate data source and endogeneity concerns, are consistent with the theories of growth and innovation incentive and suggest corporate innovation represents a channel by which employee treatment enhances firm value. In the second chapter I use the context of mergers & acquisitions (M&A) to investigate the effect of firm innovative ability. Acquirer announcement returns in M&A are known for being low on average; however, recent studies indicate greater abnormal announcement and long-run returns to firms motivated by the acquisition of innovation. Although acquiring innovation is an important motive for M&A, prior studies have ii mostly focused on the characteristics of target firms. In this paper, I explore the effect of acquirers’ innovative abilities in the M&A transaction. I propose that acquirer’s ex-ante ability to transform internal and external innovation investment into a tangible valued output (i.e. sales or profitability) is subject to asymmetric information. I apply a unique measure of innovative ability to explain the cross-sectional variation in acquirer returns for mergers and find a positive relation between acquirers’ innovative abilities and their abnormal returns around M&A announcements. I further discover that greater CARs in high innovative ability acquirers only exist in a subsample of M&As in the later life cycle of firms. For early merger events (the first three M&As after IPOs), acquirers’ innovative abilities are not associated with significantly larger announcement returns, suggesting an altered market perception of the value impact of acquisitions of innovation and innovative ability. / Business Administration/Finance

SOFTWARE PATENTS : A study on the patentability of software inventions

Achieng, Spance Joy January 2017 (has links)
The primary objective of the thesis will be to focus on patent protection of software under the European Patent Convention, by analyzing the different approaches that the European Patent Office has taken into consideration since the mid-1980s. These approaches are derived from the different decisions that emanate from the Technical Boards of Appeal of the European Patent Office. The thesis will examine the most relevant decisions illustrating the juridical tendencies and basis that have been utilized to decide over the patentability of computer programs. The analysis will conclude with the latest approach taken by the Technical Board of the European Patent Office. The study will examine the patentability requirements of inventions in general established within the European Patent Convention. Sources that will be utilized to carry out this research will include case law, legislation, specialized legal commentary; journals and books. The present study sustains that computer programs may be patented as long as they comply with all the general requirements of an invention prescribed under the European Patent Convention together with the condition established by case law called the technical character requirement. Nevertheless, due to the fact that the Technical Boards of Appeal are not bound by previous case law, the current position could keep evolving as it relies on the stance of  the European Patent Office on patentability of computer programs which is seems to be influenced by the changes in the technological world

Essays on the propensity to patent: measurement and determinants

de Rassenfosse, Gaétan 28 May 2010 (has links)
Chapter 1 discusses the econometric pitfalls associated with the use of patent production functions to study the invention process. It then goes on to argue that a sound understanding of the invention process necessarily requires an understanding of the propensity to patent. The empirical analysis carried out in Chapter 1 seeks to explain the proportion of inventions patented – a potential metric for the propensity to patent – from an international sample of manufacturing firms. <p><p>Chapter 2 proposes a methodology to filter out the noise induced by varying patent practices in the R&D-patent relationship. The methodology explicitly decomposes the patent-to-R&D ratio into its components of productivity and propensity. It is then applied to a novel data set of priority patent applications in four countries and six industries.<p><p>Chapter 3 takes stock of the literature on the role of fees in patent systems while Chapter 4 presents estimates of the price elasticity of demand for patents at the trilateral offices (that is, in the U.S. Japan and Europe). The estimation of dynamic panel data models of patent applications suggests that the long-term price elasticity is about -0.30.<p> / Doctorat en Sciences économiques et de gestion / info:eu-repo/semantics/nonPublished

The practical accomplishment of novelty in the UK patent system

Sugden, Christopher Michael Gordon January 2011 (has links)
Novelty is a widespread notion that has not been given commensurate critical attention. This research is an ethnographically-inclined exploration of practices surrounding the accomplishment of novelty in an institution for which novelty is a central notion: the patent system of the United Kingdom. The research is based on interviews with patent examiners at the UK patent office, interviews with patent attorneys at various legal firms, and documentary analysis of legislation and numerous legal judgments. The thesis brings to bear themes from Science and Technology Studies and ethnomethodology to assess the extent to which they can account for the practices surrounding novelty in the UK patent system. As a fundamental legal requirement for the patentability of inventions, novelty is a central part of the practices of patent composition, assessment and contestation. Rather than being a straightforward technical criterion, however, novelty is shown to be a complex and heterogeneous phenomenon emerging from interwoven legal, bureaucratic and individual practices. The local resolution of whether or not a given invention is new, and the cross-institutional coherence of novelty as a practicable notion, raise questions concerning ontology, accountability, scale and inconcludability, and provide an opportunity for empirically grounded engagement with these longstanding analytical concerns.
