Technology sourcing and output of established firms in a regime of encompassing technological change

This paper argues that when the technological basis of an industry is changing, the firm's approach to technology sourcing plays a critical role in building the capabilities needed to generate new technical outputs. Using survey and archival data from the U.S. pharmaceutical industry during the period 1981–91, we find that different approaches to technology sourcing (internal R&D and external R&D) are related to different types of biotechnology‐based output at the end of the period. Internal R&D was positively associated with patent output. Acquisition activity was positively related to number of biotechnology‐based products. Greater use of R&D contracts and licenses was associated with stronger reputation for possessing expertise in biotechnology. These findings underscore the importance of taking a multifaceted approach to technology sourcing in order to build the absorptive capacity needed to generate new technical output. Surprisingly, we also found that involvement in joint ventures was negatively related to patent output. This raises interesting questions about the strategic use of joint ventures in a regime of encompassing technological change. Copyright © 2003 John Wiley & Sons, Ltd.     

PROFESSIONALIZATION AND BRITISH MANAGEMENT PRACTICEPROFESSIONALIZATION AND BRITISH MANAGEMENT PRACTICE: CASE EVIDENCE FROM MEDIUM-SIZED FIRMS IN TWO INDUSTRIAL SECTORS*

High levels of occupational specialization, problems of cross-functional integration and distinct bureaucratic tendencies have traditionally been seen as problems endemic to British management practice. Over the last decade, these problems are expected to have disappeared - or at least diminished - as major developments in management and organizational theory, as well as changing economic circumstances, have redirected management thinking towards ‘new’ ideas of flatter, simpler organizational structures, increased flexibility and decentralization, improvements in the quality of inter-functional relations and the like. Yet, despite these developments, there is comparatively little research that has investigated actual patterns of change within management and, in particular, what is happening in what could be regarded as the mainstream of British industry - namely, ‘ordinary’, medium-sized firms operating in ‘traditional’ industrial sectors. Moreover, rarely does such research focus upon the implications of management change for the strategies of professionalization adopted by competing specialist occupational groups within management. This paper sets out to help fill these gaps, by reporting the findings from case studies of four such firms, taking into account the particular contexts and historical circumstances that have helped shape any such change and drawing out the key influences on changed management practice.     

A NO-ARBITRAGE MARTINGALE ANALYSIS FOR JUMP-DIFFUSION VALUATION

This study presents a jump-diffusion valuation framework using the no-arbitrage martingale approach. Equilibrium conditions needed to support a jump-diffusion pricing standard process are derived. The results are a generalized jump-diffusion security market line and its corresponding equilibrium valuation relation that prices both jump and diffusion risk. To value options, a fundamental formula is derived that includes existing jump-diffusion option valuation formulas as special cases. 1 find Merton's (1976a) assumption of diversifiable jump risk to be consistent with no-arbitrage only when the aggregate consumption flow does not jump. Simulation shows that Merton's formula undervalues/overvalues options on hedging/cyclical assets. When the jump arrival frequency is larger, the mispricing is larger/smaller for in-the-money/out-of-the-money options.     

Leadership in your midst: tapping the hidden strengths of minority executives

All companies value leadership-some of them enough to invest dearly in cultivating it. But few management teams seem to value one engine of leadership development that is right under their noses, churning out the kind of talent they need most. It's the complicated, overburdened but very rich lives of their minority managers. Minority professionals-particularly women of color-are called upon inordinately to lend their skills and guidance to activities outside their jobs. Sylvia Ann Hewlett, who heads the Center for Work-Life Policy, and her coauthors, Carolyn Buck Luce of Ernst & Young and Cornel West of Princeton, present new research on the extent to which minority professionals take on community service and other responsibilities outside the workplace and more than their share of recruiting, mentoring, and committee work within the workplace. These invisible lives, argue the authors, can be a source of competitive strength if companies can learn to recognize and further cultivate the cultural capital they represent. But it's hard to convince minority professionals that their employer respects and values their off-hours responsibilities. A lack of trust keeps many people from revealing much about their personal lives. The authors outline four ways companies can leverage hidden skills: Develop a new level of awareness of minority professionals' invisible lives; appreciate the outsize burdens these professionals carry and try to lighten them; build trust by putting teeth into diversity goals; and, to finish the job of leadership development, help minorities reflect on their off-hours experiences, extract and generalize the lessons, and apply what's been learned in other settings.     

The Pricing of Lake Lots

This article reveals aspects of lakefront property pricing especially with respect to lot frontage and depth. A clearer understanding of how these lot dimensions affect price should be of interest to those engaged in lake development, land use control, valuation, and marketing. A data set with eighty observations of vacant Lake Michigan residential properties sales is used. The unique geography of northwest Michigan provides an opportunity to tackle empirical issues associated with zoning when zoning is correlated with lot attributes, such as lot topography.     

Housing Density and the Effect of Proximity to Public Open Space in Aberdeen, Scotland

We consider whether public recreational open space is a substitute for private open space by testing whether price effects from proximity to an urban park are increasing in housing density. Aberdeen, Scotland features three owner-occupied residential property types: detached housing, nondetached housing and flats. We examine property sales within 800 m of five city parks. We find flat prices increase with additional proximity to parks, but there are generally no price effects from park proximity for lower density housing types. The results suggest that open space policy must consider the scale and density of surrounding urban development.     

Four tigers and the dragon: values differences,similarities, and consensus

This study examines the influence of economic and political factors that contribute to the convergence and/or divergence in value priorities of five East Asian societies—China, Hong Kong, Singapore, South Korea, and Taiwan. We find that political and social-economic factors influence the values orientations of managers within this region. However, economic development level is an insufficient explanation for values convergence without consideration of the societal context and cultural traditions in which that development occurred.

Networks,trust, and risk mitigation during the American Revolutionary War: a case study

This article takes a case study approach to the question of how entrepreneurs developed and used networks to support trade during the American Revolutionary War (American War of Independence). Using the business letter books of Daniel Eccleston of Lancaster, covering January 1780 to December 1781, the article shows how he used trust‐building activities and developed open networks in Britain and the West Indies in order to build, sustain, maintain, and diversify his commercial activities to reduce risk and develop new opportunities. Eccleston's letters illustrate a competitive market in which entrepreneurs helped drive the industrial revolution through stimulating demand and encouraging trade. They show that mutual trust was the foundation of strong networks, and that networks were significant in underpinning entrepreneurial success through allowing the mitigation of business risk and offering the opportunity for diversification supported by the network. The article makes use of the work of Casson, Pearson and Richardson, and Wilson and Pop.
