In Search of the Classics: A Study of the Impact of JPIM Papers from 1984 to 2003*

The Journal of Product Innovation Management (JPIM) was launched in 1984 and over its first two decades of existence evolved into the leading journal in the field of innovation and the management of technology. During these 20 years JPIM contributed to the field by publishing 488 academic papers. This paper is a follow‐up study to an earlier study that looked at how JPIM evolved in terms of knowledge stock and knowledge flows during the first two decades (published in JPIM, March 2007). That paper looked at what was published during the first 20 years, which sources were cited, and which journals cited JPIM papers. This study takes a closer look at the impact of JPIM on the field of innovation and the management of technology by identifying the most classic papers published in JPIM during its first two decades of existence. This study used multiple research methods to identify 64 candidate potential classics from the 488 papers published in the first 20 years of JPIM's existence, to analyze how they differ from the other 424 papers published in the journal, and to investigate authors' motivations for writing these papers. Finally, using survey responses from the Product Development and Management Association (PDMA) membership and other academics in innovation and new product development, the research then determines which 5 of the 64 candidate papers are considered to be the “most classic” papers published and the factors driving that determination. The findings show that classic papers are those presenting a “pioneering idea” in the field that creates buzz in both the academic and practitioner worlds. High numbers of citations are indeed the outcome of these endeavors, but being a classic requires more than having high numbers of citations. Authors of the true classics generally have worked hard to disseminate their research, usually to both academics and practitioners, perhaps also contributing to the network buzz created by their findings. While one of the five most classic papers represented the first investigation into a particular stream of research, the other four were culminations of a significant body of research, providing a distinct summary of known information on a topic at the time they were published and a clear road forward for future research on the topic. These bodies of knowledge have yet to be superseded by other culminating papers.     

Boards of directors in family firms: a generational perspective

The purpose of this study is to advance the understanding of boards of directors in family firms. Building on generational changes in family attributes, we argue that firms in a different generational phase have different governance needs and characteristics. With regard to board task needs, the empirical results indicate a convex generational evolution in the need for board advice, and a rise over the generations in the need for board control. With regard to board composition, we find that the likelihood of having an outside director on the board has a convex generational trend. This relationship seems to be fully mediated by the firm’s board task needs. Furthermore, the number of family directors seems to increase over the generations. This study demonstrates that it is important to consider the generational phase of the family firm in order to understand its governance system.

Loosely Coupled Results Control in Dutch Municipalities

This paper analyses the implementation of the ‘dual system’ in Dutch municipalities which was part of a package of New Public Management‐reforms. This system was stimulated by Dutch central government and called for more accountability for performance of municipal managers and the board of mayor and aldermen, as well as for the use of more output and outcome information. Interviews of participants on four different hierarchical levels in 12 municipalities show that the practices of output management at different hierarchical levels are only loosely coupled to each other (‘vertical loose coupling’). We also found some degree of ‘horizontal loose coupling’ at each hierarchical level between result orientation, the development of output indicators and the use of output information for performance evaluation. The paper analyses the reasons why municipalities encounter difficulties in designing a comprehensive and coherent performance management system.     

The Personal Development Plan Practice Questionnaire: the development and validation of an instrument to assess the employee's perception of personal development plan practice

Confronted with the speed of technological advancements and increasing global competition, organizations have come to realize that their employees' continuous learning drives business success. A popular tool to support and enhance continuous learning is the personal development plan (PDP). Despite its popularity, empirical evidence of the effectiveness of the PDP is scarce. To date, most of the research on the practice of the PDP is conducted within educational (students) and health (general practitioners) settings and not within business environments. Moreover, research methodology is restricted to qualitative methods and survey research is rare. For that reason, we developed and validated a questionnaire to assess PDP practice. To develop the questionnaire, we relied on literature on portfolio assessment in the educational context and the workplace (health and education); to validate it, we collected data in three independent organizations. To assess the factor structure of the questionnaire, exploratory principal component factor analyses with direct oblimin rotation were conducted on data sets from two organizations. Factor reliability was computed using Cronbach's alpha coefficient. The principal component analysis resulted in a 35‐item questionnaire containing five factors each with high internal validity. Cronbach's alphas ranged between 0.63 and 0.91. Next, a confirmatory factor analysis was conducted on an independent sample of 287 employees, working in a third organization. The results from this analysis were used to further refine the instrument. The present instrument provides a reliable and valid measure of the employee's perception of the PDP practice in the workplace, consisting of four scales and 19 items.     

Twenty Years of the Journal of Product Innovation Management: History, Participants, and Knowledge Stock and Flows

The Journal of Product Innovation Management (JPIM) serves as a marketplace for science‐based, innovative ideas that are produced and consumed by scholars and businesspeople. Now that JPIM has existed for 20 years, two intriguing questions emerge: (1) How has the journal evolved over time in terms of knowledge stock, that is, what are the characteristics of the growing stock of knowledge published by JPIM over the years; and (2) how has the journal evolved in knowledge flow, that is, how is JPIM influenced by other scientific publications and what is its impact on other journals? In terms of knowledge stock, over 35% of the articles published over the 20 years investigate processes and metrics for performance management. The next most frequently published area was strategy, planning, and decision making (20%), followed by customer and market research (17%). The dominant research method used was a cross‐sectional large‐sample survey, and the focus most usually is at the project level of the firm. The large majority of JPIM authors (60%) have a marketing background, with the remaining 40% representing numerous functional domains. Academics at all levels publish in JPIM, and though most authors hail from North America, the Dutch are a significant second group. JPIM was analyzed from a knowledge‐flow perspective by looking at the scientific sources used by JPIM authors to develop their ideas and articles. To this end a bibliometric analysis was performed by analyzing all references in articles published in JPIM. During 1984–2003 JPIM published 488 articles, containing 10,314 references to journals and 6,533 references to other sources. Some 20% of these references (2,020) were self‐references to JPIM articles. The remaining 8,294 journal references were to articles in 287 journals in the fields of management (25%), marketing (24%), and management of technology (14%). However, it should be pointed out that many domains were dominated by a limited number of journals. The second component of knowledge flow concerns the extent to which the ideas developed in JPIM are consumed by other authors. Again, bibliometric analysis was used to analyze data from the Social Sciences Citation Index (SSCI) about citations to JPIM in other journals. For the period 1984–2005, the SSCI registered 7,773 citations to JPIM in 2,067 articles published in 278 journals (including the 2,020 self‐citations in JPIM). The functional areas most frequently citing JPIM are management of technology (25%), marketing (15%), management (14%), and operations management and management science (9%). Again, several domains were found to be dominated by a limited number of journals. At the level of individual journals the analysis shows a growing impact of JPIM on management of technology journals. The knowledge‐flow analysis demonstrates how JPIM functions as a bridge between the knowledge from various domains and the body of knowledge on management of technology. It suggests a growing specialization of the field of technology innovation management, with JPIM being firmly entrenched as the acknowledged leading journal.     

Unemployment and Catching Up: Europe Vis-à-vis the USA

This paper develops a two-region two-sector endogenous growth model with a dual labour market based on efficiency wages. Growth is driven by research done in the (high-tech) tradeables sector. The follower region tends to catch up in terms of labour productivity with the leader region. Differences in unemployment compensation systems can lead to relative convergence, i.e., a steady state with the backward region lagging behind the leader region. The reason for this is that high social welfare compensations generate high unemployment and reduce the amount of labour employed for R&D purposes.     

Stability through cycles

Economic variables like GDP growth, employment, interest rates and consumption show signs of cyclical behavior. Many variables display multiple cycles, with periods ranging in between 5 to even up to 100 years. We argue that multiple cycles can be associated with long-run stability of the economic system, provided that the cycle periods are such that interference is rare or absent. For a large sample of important variables, including key variables for the US, UK and the Netherlands, we document that this is indeed the case.     

State regulation and university behavior

The impact of state regulation on the economic behavior of American public research universities is studied, using a unique sample of data on costs, outputs and regulation measures for 98 institutions. The university cost structure is modeled by a multiple output translog cost function, explicitly allowing for the impact of state regulation. Regulating non-faculty salary expenditures and the spending of non-state revenues decreases costs, while regulating faculty salary expenditures increases costs, given the same output levels. The results are interpreted in terms of the principal-agent relationship of state regulators and universities. Efficiency gains and losses depend on the relative accuracy of state information on the production process.     

CONSTANT WEALTH NATIONAL INCOME: ACCOUNTING FOR WAR DAMAGE WITH AN APPLICATION TO THE NETHERLANDS, 1940–45

The issue of the proper way to address and document crisis and disaster in the national accounts is brought into focus by analyzing a practical case: the damage caused by the Second World War as discussed at a 1945 Paris reparations conference. It is concluded that "what if" damage e.g. output not produced due to the war should not be included in the national accounts, but factual damage should. The method by which factual damage should be included must then be decided. The option of just showing the damage in the reconciliation accounts is rejected. Instead the introduction of an additional income concept into the accounts, constant wealth national income is proposed. This Hicksian concept deducts from standard national income the damage to all produced goods lasting longer than a year. The concept is illustrated with guesstimates for the Netherlands, 1940–45. Finally, by way of an illustration, the paper employs 1945 estimates of damage in the Netherlands in order to arrive at a constant wealth national income for 1940–45. It is shown that, in 1938 prices, constant wealth national income is very much lower than standard national income and thus far better reflects the decline in prosperity during these years.
