The potential of a theory based on organizational memes in coevolution with the environment has been postulated, but remains
empirically under-developed. This study explores whether understanding organizational memetic variation is empirically possible
and, if so, whether it might, with further development, provide managers with early indications of a misalignment between
organizational action (operationalized as memetic variation) and strategic intent—the amount of memetic variation needed to
stay aligned with the competitive environment. A method for empirically identifying knowledge-based memes in everyday practice
is developed. It stems from modern advances in genetics allowing micro-level changes in genes to be linked to macro-environmental
dynamics. Using the concept that memetic variation is caused by everyday, uncontrollable uncertainties of interpretation,
memetic variation is reduced to seven categorical types. A highly exploratory quasi-experimental design allows a preliminary
comparison of a would-be innovative ‘Portfolio Management Committee’ with self-organizing Internet chat-room settings that
are representational of open-source innovation. Results are consistent with predictions showing that higher levels of variation
are seen in the latter, despite the former’s strategic intent of innovating to stay aligned with a dynamic environment. Further
work is needed, however, to test reliability and validity.

Modern theories of inflation incorporate a vertical long-run Phillips curve and are usually estimated using techniques that ignore the non-stationary behaviour of inflation. Consequently, the estimates obtained are imprecise and unable to test the veracity of a vertical long-run Phillips curve. We estimate a Phillips curve model taking into account the non-stationary properties in inflation and identify a small but significant positive relationship between inflation and unemployment. The results also provide some evidence that the trade-off between inflation and the rate of unemployment in the short-run worsens as the mean rate of inflation increases. 相似文献

We exploit the information derived from geographical coordinates to endogenously identify spatial regimes in technologies that are the result of a variety of complex, dynamic interactions among site-specific environmental variables and farmer decision making about technology, which are often not observed at the farm level. Controlling for unobserved heterogeneity is a fundamental challenge in empirical research, as failing to do so can produce model misspecification and preclude causal inference. In this article, we adopt a two-step procedure to deal with unobserved spatial heterogeneity, while accounting for spatial dependence in a cross-sectional setting. The first step of the procedure takes explicitly unobserved spatial heterogeneity into account to endogenously identify subsets of farms that follow a similar local production econometric model, i.e. spatial production regimes. The second step consists in the specification of a spatial autoregressive model with autoregressive disturbances and spatial regimes. The method is applied to two regional samples of olive growing farms in Italy. The main finding is that the identification of spatial regimes can help drawing a more detailed picture of the production environment and provide more accurate information to guide extension services and policy makers. 相似文献

This paper models the volatility of national stock market returns of the G-7 countries using ARCH and GARCH modeling techniques. Then, via the use of vector autoregression analysis, the international transmission of volatility among the countries is explored for the period between April 1973 and July 1990. Variance decompositions are calculated in order to quantify the impacts of volatility shocks in one market on the others. Impulse response functions are used to inspect the dynamic responses of domestic and foreign volatility shocks. Results indicate that volatility transmission among the G-7 countries is the norm in the post-Bretton Woods era. Further, we find that volatility shocks are generally absorbed within six to nine months. 相似文献

Answering the call for alternative approaches to researching project management, we explore the evaluation of project success from a subjectivist perspective. An in‐depth, longitudinal case study of information systems development in a large manufacturing company was used to investigate how various project stakeholders subjectively perceived the project outcome and what evaluation criteria they drew on in doing so. A conceptual framework is developed for understanding and analyzing evaluations of project success, both formal and informal. The framework highlights how different stakeholder perspectives influence the perceived outcome(s) of a project, and how project evaluations may differ between stakeholders and across time. 相似文献

Creativity is acknowledged to be important for economic growth and as an everyday life-skill, however several influential reports have suggested that education could do more to harness creative talent. Creative cognition literature suggests the lack of creativity is at least partly the result of ‘fixation’ (difficulty in generating novel ideas due to imagination being ‘structured’ by existing knowledge). This paper focuses on the secondary (students aged 11–16 years) design and technology (D&T) context in the UK. Here we examine whether teacher practice can contribute to fixation by focusing on one specific facet of teacher practice in D&T; the use of product analysis to inform the generation of creative design ideas. Data is drawn from the preliminary phase of a research and intervention project from interviews with D&T teachers (N = 14), students (N = 126) and lesson observations (N = 10) and an analysis of documents and student work. Product analysis is widely used at different points in design projects but, as is shown, in all cases current practice can lead to fixation, as thinking is constrained down specific paths and tasks are at best at procedural rather than comprehension level. The implications of these findings and tentative ways forward for practitioners are discussed. 相似文献

The paper proposes a two-stage mixed duopoly model of exhaustible resource market where at the first stage the government decides on the degree of privatization of public firm and at the second stage the public and private firms decide simultaneously on the two-period extraction paths. It is demonstrated that if the two firms have symmetric technologies with increasing marginal extraction costs and the same resource stocks, then neither full nationalization of any of the two firms nor full privatization will be socially desirable. It is shown that the presence of a semi-public firm improves intertemporal allocation of the fixed resource stock. Thus, partial privatization is optimal even under exogenously fixed total outputs of each firm. For asymmetric cost case, when the public firm is less efficient than the private firm, we derive the conditions under which full nationalization or full privatization is optimal. 相似文献

Biotechnology is causing dramatic changes in the seed industry on a national and global level. Further, the delivery of technology through seed is affecting all aspects of crop production. Coined the Third Wave of Development, it is a drive to meet specific end use traits through biotechnology. In light of this, the industry is seeing increased integration between all those involved in the chain of production. Adapting to this new environment creates significant challenges for the industry, including regulatory, international, handling, and structural.
As the Canadian seed industry changes dramatically to meet the specific needs of end users, there has been an increase in strategic alliances between both handling and seed companies to accommodate identity preserved production. There has also been an increase in mergers and acquisitions, as R&D companies attempt to marry novel trait developments with good germplasm and seed production expertise.
Yet, this is only the beginning as the integration of the seed industry with other aspects of the crop inputs sector applies even more pressure to integrate the agri-food industry right from plant breeding through to end use. 相似文献
