Bayesian inference for the mover–stayer model in continuous time with an application to labour market transition data

This paper presents Bayesian inference procedures for the continuous time mover–stayer model applied to labour market transition data collected in discrete time. These methods allow us to derive the probability of embeddability of the discrete‐time modelling with the continuous‐time one. A special emphasis is put on two alternative procedures, namely the importance sampling algorithm and a new Gibbs sampling algorithm. Transition intensities, proportions of stayers and functions of these parameters are then estimated with the Gibbs sampling algorithm for individual transition data coming from the French Labour Force Surveys collected over the period 1986–2000.

Technical analysis compared to mathematical models based methods under parameters mis-specification

In this study, we compare the performance of trading strategies based on possibly mis-specified mathematical models with a trading strategy based on a technical trading rule. In both cases, the trader attempts to predict a change in the drift of the stock return occurring at an unknown time. We explicitly compute the trader’s expected logarithmic utility of wealth for the various trading strategies. We next rely on Monte Carlo numerical experiments to compare their performance. The simulations show that under parameter mis-specification, the technical analysis technique out-performs the optimal allocation strategy but not the Model and Detect strategies. The latter strategies dominance is confirmed under parameter mis-specification as long as the two stock returns’ drifts are high in absolute terms.     

Institute for the future's study of the UK, 1978–1995

The method used expert opinions (collected through interviews), scenario generation, and a simple econometric model. Some methodological innovations are reported; eg aids to assist experts in thinking ahead, and in how scenarios are generated and aggregated.     

Leverage and investment in diversified firms

Within diversified firms, the negative impact of leverage on investment is significantly greater for high q than for low q segments and significantly greater for non-core than for core segments. This differs substantially from focused firms and is consistent with the view that diversified firms allocate a disproportionate share of their debt service burden to their higher q and non-core segments. We also find that, among low-growth firms, the positive relation between leverage and firm value is significantly weaker in diversified firms than in focused firms. We conclude that the disciplinary benefits of debt are partially offset by the additional managerial discretion in allocating debt service that is provided by the diversified organizational structure.     

Asian development and poverty reduction strategies: Integrating fisheries into the development discourse

Asia is the world’s foremost capture fishery and aquaculture producer. It is also home to the majority of the world’s fishers and marine fleet (decked and undecked). Consequently, there is every reason to expect that this importance is reflected in national development discourses. This article identifies the socio-economic importance of fisheries in the region in terms of its contribution to primary exports, domestic protein consumption, employment and poverty alleviation. We then analyse national development and poverty reduction strategy documents using a content analysis methodology previously applied to measure the extent to which environmental or forestry issues had been mainstreamed into national policy documents. This enables us to identify those countries that have currently integrated fisheries into the national development discourse – and those that have not. We conclude by proposing two strategies to enable the more effective integration of fisheries into the development agenda.     

Hybrid Choice Models: Progress and Challenges

We discuss the development of predictive choice models that go beyond the random utility model in its narrowest formulation. Such approaches incorporate several elements of cognitive process that have been identified as important to the choice process, including strong dependence on history and context, perception formation, and latent constraints. A flexible and practical hybrid choice model is presented that integrates many types of discrete choice modeling methods, draws on different types of data, and allows for flexible disturbances and explicit modeling of latent psychological explanatory variables, heterogeneity, and latent segmentation. Both progress and challenges related to the development of the hybrid choice model are presented.     

Interlocking Directorates, Firm Strategies, and Performance in Hong Kong: Towards a Research Agenda

Filling a gap in the interlocks literature which has been largely centered on the West, we present preliminary data on the pattern of interlocking directorates among the top 200 largest corporations in pre-1997 Hong Kong. Then we identify four separate groups of firms in Hong Kong, and suggest propositions based on the resource dependence perspective on the critical relationships among their interlocking directorates, firm strategies, and performance. These propositions have the potential to form the building block of an emerging research agenda that will shed light on the role of interlocking directorates in an increasingly important part of the world.     

Union Representatives in Labour–Management Partnerships: Roles and Identities in Flux

This study examines the challenges met by union representatives (URs) who have to reconstruct their traditional role in the context of labour–management partnerships. They are innovators involved in the transition to renewed labour relations. Identity issues and role conflicts are examined through an in‐depth analysis of the process involved in assimilating this new role in unionized organizations. The results suggest that URs subordinate the partner role to the interest representation role. Interviews suggest that this enhanced union legitimacy. Some blurring of traditional social categories such as those of employee or employer is possible to the extent that the relations between the actors are founded on interpersonal relations.     

FTA and equity: New approaches to governance

FTA and equity addresses the need for multiple stakeholders’ participation in public policy and corporate decision making thus leading to more democratic societies. The need for more participative and inclusive decision making is due to the move from the technocratic nature of decision making towards more democratic processes, which is a result of the transformation of societies and situations as a result of various factors including globalisation, environmental concerns, more knowledge intensive work and lifestyle.The current paper addresses Future-oriented Technology Analyses (FTA) in the context of a better understanding of issues that ought to be considered by the FTA community so that it can support the quest for new forms of governance. The paper has been structured on the discussion of governance around three pillars: socio-cultural evolution, corporate industrial activity and government.Analysis of the relationship between governance and each of the three pillars poses a number of questions to the FTA community that reflect on the potential impacts of FTA activities in governance. Setting a new landscape for the FTA, the paper concludes with those issues where the FTA community is starting to devote attention, as well as those it still ought to consider.
