A Longitudinal Study of the Impact of R&D,Patents, and Product Innovation on Firm Performance

Because of increasing levels of competition and decreasing product life cycles, a firm's ability to generate a continuous stream of innovations may be more important than ever in allowing a firm to improve profitability and maintain competitive advantage This paper investigates several issues that are central to an examination of the innovation productivity in a firm. First, the relationship between a firm's commitment to research and development and its innovative outcomes is examined. Two innovative outcomes are analyzed: (1) invention, which focuses on the development of new ideas; and (2) innovation, the development of commercially viable products or services from creative ideas. Invention is measured by the number of patents granted, and innovation is assessed by the number of new product announcements. Second, because many inventions ultimately result in marketable innovations and because patents may provide protection for new products, the relationship between patents and product announcements is also investigated. Finally, the ability of a firm to benefit from its inventions and innovations is studied by examining their separate effects on firm performance, measured as return on assets (ROA) and sales growth. Drawing from a sample of 272 firms in 35 industries over 19 years, the results from a model of simultaneous equations provided support for some of the hypotheses, but several other surprising findings were found. As expected, R&D spending was positively related to patents. This finding is consistent with others who argue that internal research capabilities, particularly those with a strong basic research component, is key to enabling a firm to generate creative outputs. More surprising was the finding of increasing returns to scale to R&D spending. While this contradicts much of the existing research, it is consistent with economic arguments for the advantages of scale in innovation. Also interesting is the finding that, while a significant curvilinear relationship exists between R&D spending and product announcements, it is not the predicted inverse‐U but instead a U‐shaped relationship. Consistent with previous work, product announcements were found to be positively related to both performance measures. A negative relationship was found between patents and both ROA and sales growth. While these findings were unexpected, they are intriguing and call into question the value of patents as protection mechanisms. In addition, these results may be resulting from the rise of strategic patenting, where an increasing number of firms are using patents as strategic weapons. As expected, a positive relationship was found between patents and new product announcements.     

Low Pay in the UK: The Case for a Three Sector Comparative Approach

This paper represents a first attempt to examine empirically the comparative extensiveness of low pay in the third sector against the theoretical backdrop of both the generic labour market literature and the newly emerging specialist third sector literature. It shows that the third sector occupies an intermediate position between relatively high concentrations of low pay in the private sector and low concentrations in the public sector. These differences do not emerge simply because the categories of vulnerable workers identified in the generic labour market literature are less likely to be found in the third sector. Nor do they reflect differences in sectoral industry and occupation composition. Theoretical explanations for these differences are to be found in the third sector literature.     

Understanding Loweswater: Interdisciplinary Research in Practice

This paper reports on a scoping study, ‘Understanding Loweswater’, funded under the Rural Economy and Land Use (RELU) programme. It highlights the research and policy context supporting the need for this kind of interdisciplinary, stakeholder‐inclusive research and explains the way that the research was carried out in practice. The scoping study identified some of the challenges of the interdisciplinary approach taken, as well as highlighted its potential for solving environmental problems that do not fit within the frame of a single discipline.     

Incumbency advantages in the Canadian Parliament

Abstract We apply a regression discontinuity approach to determine incumbency advantages in the Canadian Parliament, finding that incumbents enjoy a 9.4–11.2% increased probability of winning over non‐incumbents. Owing to the presence of multiple parties, an incumbency advantage in terms of vote share does not always translate to an increased probability of winning, because incumbents do not necessarily obtain votes from their closest opponent. Also, under the assumption that strategic exit is not an issue, we are able to split the incumbency advantage into party incumbency and individual candidate incumbency components, finding that the advantage is almost entirely due to the individual.     

Computer algebra in probability and statistics

This paper discusses the uses of computer algebra within statistics and probability. A distinction is drawn between the use of computer algebra packages to support investigations, by performing calculations, ankl their use to implement structure; to build in elements of a theory (such as stochastic calculus or the Taylor string theory of Barndorff Nielsen and others) as a preliminary to research investigations. Brief surveys are given of instances in the literature of use of computer algebra in probability and statistics. Two examples of implementations of structure are discussed, both drawn from the author's own work with the computer algebra package REDUCE. One is a simple demonstration using moments of the Poisson distribution. The other is itovsn3 , an implementation of the semimartingale stochastic calculus. It is described how itovsn3 may be used to derive the characteristic function of the Lévy stochastic area, following a proof due to S. Janson. Prospects for future work and for work in progress are discussed.     

How badly do we need theory Z?

In Theory Z-style management everybody participates in corporate decision making. This more open process should give us fewer Pintos, Love Canals, and massive international payoffs as executives are forced to expose their reasoning to the moral sensibilities of the whole corporation. So far everything looks good. But we are a long way from showing that only corporations so managed can be fully moral. Yet Dwiggins seems to believe this, putting his faith in the basic goodness of the many while virtually dismissing the managers as mere technicians. This is too slick; even if it describes our average corporation today, there are plenty of less radical changes which can also produce the desired moral corporation. Good leadership which acts on their commitment to improve the company is surely one historically respectable alternative; cynicism about the present crop of leaders should not distract us from investigating this route. Finally, I wonder if Dwiggins can consistently urge us to embrace a full-scale Theory Z organizational structure, given his position on the place of ethics and profitability.
