New technology based firms and the emergence of new industries: some employment implications

This article challenges conventional theories on the role of NTBFs in the growth of new industries. Its'community dynamics'approach is an alternative to the SPRU model of'dynamic complementaries'and argues that while NTBFs are crucial, their capacity for employment generation is low.     

Great deeds or great risks? Scientists’ social representations of nanotechnology

Nanotechnologies are becoming a larger presence in everyday life and are viewed by governments and economic actors as a key area for development. The theory of social representations suggests that specialist views eventually disseminate to shape representations among the public. Yet nanotechnologies remain relatively little known to the general public. The media emphasize potential benefits, while potential risks get less attention. The literature has not yet addressed whether representations by a well-informed population (scientists) are indeed structured in terms of the risk–benefit polarity that dominates research framing to date. We attempted a systematic assessment of how background knowledge about nanotechnology may influence experts’ perception. Study 1 delivered the first demonstration derived from a qualitative analysis confirming the existence of a polarized representation of nanotechnologies, contrasting opportunity (medical, economic, and technological) and risk. Interestingly, risk was distinguished at two levels: that associated with nanomaterial characteristics (toxicity, reactivity) and at the larger scale of impact (health, environment, legislation). Does this polarity indicate a ‘yes, but’ logic (nanotechnology carries opportunity but also risk), or two clusters of specialists (sensitive, respectively, to opportunity or to risk)? Study 2 surveyed a larger sample of experts who self-described their scientific background and role viz. nanotechnology. Role had no influence. Specialists consensually viewed that nanotechnology represents opportunity, but depending on scientific background they did not agree to the same extent that nanotechnology also constitutes a risk. Participants with a physics and chemistry background tended to represent nanotechnologies predominantly in terms of opportunities and not in terms of inherent risks or impacts. In contrast, toxicologists, life and social scientists appeared to explicitly incorporate both benefits and risks in their representation of this new technology. Environmental scientists were a more diverse group, divided between the two patterns of representation.     

Social Capital Effects on the Career and Development Outcomes of HR Professionals

HR professionals’ roles require them to be responsive to both employee needs and top management strategies. However, the need to respond to the often competing employee and strategic agendas makes relationship‐building efforts challenging. This study examines the social capital characteristics of HR professionals and the impact on receipt of network benefits and career outcomes. Results indicate that HR professionals benefit from relationships with other HR professionals for career sponsorship and role‐related benefits. However, it is contacts who are in higher positions or in other organizations that transfer the most influential benefits, which in turn relate to objective career outcomes. Few benefits are obtained from contacts in non‐HR functions. The results illuminate relationship development opportunities for HR professionals. © 2015 Wiley Periodicals, Inc.     

The dynamics of Central European equity market comovements

This paper examines short-term and long-term comovements between developed European Union (EU) stock markets and those of three Central European (CE) countries which recently joined the EU. Dynamic cointegration and principal components methods are applied, in addition to static tests. While we find no evidence of cointegration for the period July 1995–February 2005 as a whole, dynamic tests reveal alternating period of cointegration disrupted by episodes dominated by short-term domestic factors. Principal components analysis reveals that a stable factor explains a large proportion of return variances. Ultimately, despite the decade-long process of alignment by CE countries with the EU, evidence of steadily increasing convergence of equity markets is lacking.     

Corporate disclosure, cost of capital and reputation: Evidence from finance directors

The majority view of the executives interviewed is that disclosure reduces the cost of equity up to the point at which a good-practice level of communication has been reached, after which there is little further effect. Greater disclosure to rating agencies and lenders reduces the cost of debt. Attitudes towards more mandatory disclosure are mostly negative. The main perceived cost of disclosure is creating the information. The main benefits are promotion of a reputation for openness and of shareholder confidence, not a lower cost of capital. We suggest that a reputation for openness is valued because it enhances the company's overall reputation, which brings commercial benefits.     

A Note on the Identification of Dynamic Economic Models with Generalized Shock Processes

Dynamic stochastic general equilibrium (DSGE) models with generalized shock processes, such as shock processes which follow a vector autoregression (VAR), have been an active area of research in recent years. Unfortunately, the structural parameters governing DSGE models are not identified when the driving process behind the model follows an unrestricted VAR. This finding implies that parameter estimates derived from recent attempts to estimate DSGE models with generalized driving processes should be treated with caution, and that there always exists a tradeoff between identification and the risk of model misspecification. However, these results also make it easier to address the issue of model misspecification by making it computationally easier to check the validity of cross‐equation restrictions.     

Rousseau's notion of envy: A comparison with modern economic theory

Abstract

The concept of envy is present both in Rousseau's economic philosophy and in modern economic theory. This paper compares these different uses of the concept and studies the relevance of the definition of envy adopted on each side, taking into account what is at stake when a notion of envy is introduced. It will be shown that Rousseau's envy cannot be expressed by modern conceptions of envy. Nevertheless, it enlightens the debate between the two competing notions of envy present in modern economic theory, revealing that the existence of envy questions the notion of self-interest.
