Application Of The Fractional Diffusion Equation For Predicting Market Behaviour, Jonathan Blackledge Oct 2010

Application Of The Fractional Diffusion Equation For Predicting Market Behaviour, Jonathan Blackledge

Articles

Most Financial modelling system rely on an underlying hypothesis known as the Eficient Market Hypothesi (EMH) including the famous BlackScholes formula for placing an option. However, the EMH has a fundamental flaw: it is based on the assumption that economic processes are normally distributed and it has long been known that this is not the case. This fundamental assumption leads to a number of shortcomings associated with using the EMH to analyse financial data which includes failure to predict the future volatility of a market share value. This paper introduces a new financial risk assessment model based on Levy statistics …


Middle Managers' Searching For Knowledge: The Repository-Interpersonal Dilemma, Esther Tippmann, Pamela Sharkey Scott, Vincent Mangematin Aug 2010

Middle Managers' Searching For Knowledge: The Repository-Interpersonal Dilemma, Esther Tippmann, Pamela Sharkey Scott, Vincent Mangematin

Conference Papers

Drawing on the organizational memory and strategy for managing knowledge literatures to develop a theoretical framework, we empirically examined the organizational memory contexts – interpersonal and repository logic - that set the broader conditions for middle managers’ knowledge searching. Contrary to most studies which examine knowledge storage processes, with the help of multiple case studies, we examined middle managers’ actual activities. Our findings reveal that in the interpersonal logic middle managers more actively engage in knowledge circulation and knowledge co-creation processes. In the repository logic instead, middle managers’ potential seemed to become confined because of cognitive inertia, leading to a …


Discourse At The Edge: Enterprise Discourse In Ireland, Brendan O'Rourke Jul 2010

Discourse At The Edge: Enterprise Discourse In Ireland, Brendan O'Rourke

Conference papers

Ireland is an economy, society and culture at the edge. It is at the edge of Europe and at the edge of both USA/UK and more mainland European or EU variants of capitalism. More recently it has been at the edge of economic crisis. Yet enterprise discourse is still central in Ireland. Enterprise discourse in Ireland is influenced by global and European Union (EU) developments. However, Irish enterprise discourse is not merely a ‘local adoption’. For example, high Irish economic growth rates during the ‘Celtic Tiger’ period have coincided with the development of the EU’s enterprise policy, thus giving the …


From Federations To Global Factories: Assessing The Contribution Of The Subsidiary Middle Manager In Today’S Mne, Donal O'Brien, Pamela Sharkey Scott, Pat Gibbons Jan 2010

From Federations To Global Factories: Assessing The Contribution Of The Subsidiary Middle Manager In Today’S Mne, Donal O'Brien, Pamela Sharkey Scott, Pat Gibbons

Articles

The evolution of MNEs (Multinational Enterprises) from rigid and hierarchical structures to more distributed authority and autonomy led to the theoretical justification for conceptualising them as a federative rather than unitary organisations (Ghoshal and Bartlett, 1990). Fundamental to the Federative MNE is the suggestion that subsidiary units, through their own actions, can modify the power base and influence MNE strategy ‘from below’ (Andersson et al., 2007). Considerable research highlights the potential of subsidiary units for knowledge creation and initiative (Birkinshaw, 1997, Rugman and Verbeke, 2001, Williams, 2009), but to date it has failed to confirm that MNEs actually operate as …


Subsidiary Entrepreneurship, Strategy Development Processes And Strategic Initiatives, Pamela Sharkey Scott, P. T. Gibbons Jan 2010

Subsidiary Entrepreneurship, Strategy Development Processes And Strategic Initiatives, Pamela Sharkey Scott, P. T. Gibbons

Conference Papers

MNCs gain competitive advantage through leveraging initiatives generated by their subsidiary networks. Yet we continue to have limited understanding of the complex conditions which promote initiatives. By integrating the subsidiary entrepreneurship literature and strategy development theory, we argue that the subsidiary’s approach to strategy development mediates the relationship between entrepreneurship and strategic initiative generation. We test our propositions on data generated from surveying the total population of Irish subsidiaries of foreign MNCs. Our findings confirm that an entrepreneurial subsidiary’s engagement in formal strategy development makes it better at generating strategic initiatives. This evidences the need for headquarters to encourage both …
