Identity, intended image, construed image, and gnreputation: An interdisciplinary framework and suggested terminology

Many scholars across various academic disciplines are investigating the following questions: What do individuals know or believe about an organization? How does a focal organization (and/or other interested entity) develop, use, and/or change this information? and How do individuals respond to what they know or believe about an organization? Cross-disciplinary research that centers on these questions is desirable and could be enhanced if researchers identify and develop consistent terminology for framing these questions. The authors work toward that end by identifying four central ‘viewpoints’ of an organization and proposing labels to represent each of these viewpoints:identity, intended image, construed image, andreputation.     

Stock market volatility forecasting: Do we need high-frequency data?

The general consensus in the volatility forecasting literature is that high-frequency volatility models outperform low-frequency volatility models. However, such a conclusion is reached when low-frequency volatility models are estimated from daily returns. Instead, we study this question considering daily, low-frequency volatility estimators based on open, high, low, and close daily prices. Our data sample consists of 18 stock market indices. We find that high-frequency volatility models tend to outperform low-frequency volatility models only for short-term forecasts. As the forecast horizon increases (up to one month), the difference in forecast accuracy becomes statistically indistinguishable for most market indices. To evaluate the practical implications of our results, we study a simple asset allocation problem. The results reveal that asset allocation based on high-frequency volatility model forecasts does not outperform asset allocation based on low-frequency volatility model forecasts.     

(De)Politicization Dynamics in Public–Private Partnerships (PPPs): Lessons from a comparison between UK and Flemish PPP policy

This article analyses the (de)politicization dynamics in complex and technical matters like public–private partnerships, which is necessary given its social impact and budgetary consequences for the years and generations to come. The global financial crisis provides an excellent window of opportunity to present this argument, because PPP policy needs to reinvent itself. We argue that PPP policy needs to be (re)politicized at the broader societal and discursive levels, which means that their public nature is recognized and that policy alternatives are debated in the public forums. The ‘Private Finance Initiative’ reassessment process in the UK may serve as an example.     

Does the Presence of Voice Imply the Absence of Silence? The Necessity to Consider Employees’ Affective Attachment and Job Engagement

Employer‐sponsored voice practices (ESVPs) are a tool used by human resource management to increase voice behavior and fulfill legal requirements for employee participation and consultation. Conceptual papers question the usefulness of ESVPs, arguing that they may promote selective expression at work in the way that employees who use ESVPs suggest work‐related process improvements (i.e., promotive voice) but still remain silent about issues that disturb smooth cooperation (i.e., cooperative silence). Prior research that treated voice and silence as being mutually exclusive cannot clarify how using ESVPs relates to voice and silence and under which conditions these links are particularly strong. Drawing from an employee survey in a UK branch of a multinational technology company, we apply a differentiated approach that treats voice and silence as separate behaviors and considers their specific motivators. Results from structural equation modeling show that even though employees use ESVPs and engage in voice, silence may still linger as a potential threat to performance and well‐being. Moreover, moderator analyses revealed that affective attachment to the organization increased and job engagement decreased the occurrence of this potentially dangerous coincidence. Our findings provide evidence for the usefulness of more differentiated approaches to employee voice and silence and indicate that factors that facilitate voice, be they formal procedures or pro‐organizational attitudes, might not suffice to overcome silence at work. We close with a discussion on ways to facilitate voice while reducing silence at the same time. © 2015 Wiley Periodicals, Inc.     

Tradeable permits for pollution control when emission location matters: What have we learned?

Our knowledge about tradeable permit approaches to pollution control has grown rapidly in the two decades in which they have received serious analytical attention. Not only have the theoretical models become more focused and the empirical work more detailed, but we have now had over a decade of experience with them in the U.S. This article draws upon economic theory, empirical studies, and actual experience with implementation to summarize what we have learned about applying tradeable permits to air pollution control in the special circumstance where the spatial aspects of the problem are a prime consideration.     

The Theory of Socially Embedded Games: Applications and Extensions to Open and Closed Games

An earlier article, drawing on the mathematical theory of rules and rule complexes, extends and generalizes game theory (GGT). The theory has been used to conceptualize and analyze diverse social relationships, roles, and games as particular types of rule complexes.For instance, a social role, as a major basis of a parent's action in a game, consists of at least four key components – which are mathematical objects – in the determination of action: value complex, model of reality (including beliefs and knowledge bases), a repertoire of acts, routines, programs, and strategies, and modality, a role-specific algorithm for determining or generating action in game settings. This article applies and extends GGT in analyses of a market bargaining game (a type of open game) and of the classical game of prisoners' dilemma (a type of closed game). The applications show the concrete effects of social embeddedness on game structuring, game interaction patterns and outcomes, and social equilibria.     

STRATEGIC ASSET ALLOCATION FOR LONG‐TERM INVESTORS: PARAMETER UNCERTAINTY AND PRIOR INFORMATION

We study the effect of parameter uncertainty on the long‐run risk for three asset classes: stocks, bills and bonds. Using a Bayesian vector autoregression with an uninformative prior we find that parameter uncertainty raises the annualized long‐run volatilities of all three asset classes proportionally with the same factor relative to volatilities that are conditional on maximum likelihood parameter estimates. As a result, the horizon effect in optimal asset allocations is much weaker compared to models in which only equity returns are subject to parameter uncertainty. Results are sensitive to alternative informative priors, but generally the term structure of risk for stocks and bonds is relatively flat for investment horizons up to 15 years.
