British trade union membership,density and decline in the 1980s: a research note

This article is concerned with British trade union membership statistics. It provides three different estimates of trade union density and considers their meaning and significance. It also assesses the reliability of union membership figures, and finally it provides fresh data on the unemployed membership of trade unions.     

How did a network of marine protected areas impact adjacent fisheries? Evidence from Australia

Marine‐protected areas (MPAs) are an effective means of improving habitat quality and biodiversity in the world’s oceans. While the advantages of MPAs as a mechanism for conservation and biodiversity are well established, the potential improvements to fishery performance resulting from a network of MPAs are still being established. Countries around the world have committed to establishing networks of MPAs within their waters by 2020, in response to the United Nations Convention on Biological Diversity. This, coupled with the increasing global demand for seafood and heavy reliance on fishery resources as a source of economic development for many coastal communities, means that an understanding of how these networks can be expected to impact fishery performance is extremely important. We use a difference‐in‐difference modelling approach to isolate the change in the fishery performance associated with the south‐east marine reserve network in Australia. We find no evidence that the economic performance of adjacent fisheries was negatively impacted by the network. This lack of impact is likely due to a network design explicitly intended to avoid effort displacement in key fisheries, along with fishery management changes intended to remove excess fishing capacity.     

On a class of discrete distributions arising from the birth-death-with-immigration process

This paper considers a class of distributions which may be regarded as the convolution of a negative binomial and a stopped-sum generalized hypergeometric factorial-moment random variables. Some properties are derived and it is shown that this class of distributions is a subset of distributions for the birth-and-death process with immigration (also reversible counter system). Formulations by mixing, limiting distributions and maximum likelihood equations are also discussed.     

R&D and Absorptive Capacity: Theory and Empirical Evidence*

This paper presents a single unified framework that integrates the theoretical literature on Schumpeterian endogenous growth and major strands of the empirical literature on R&D, productivity growth and productivity convergence. Starting from a structural model of endogenous growth following Aghion and Howitt (1992, 1998) , we provide microeconomic foundations for the reduced‐form equations for total factor productivity (TFP) growth frequently estimated empirically using industry‐level data. R&D affects both innovation and the assimilation of others’ discoveries (“absorptive capacity”). Long‐run cross‐country differences in productivity emerge endogenously, and the analysis implies that many existing studies underestimate R&D's social rate of return by neglecting absorptive capacity.     

Some notes on the non-central negative binomial distribution

Summary In this paper we shall record some facts and further examine certain properties of the non-central negative binomial (NNB) distribution (Laguerre series distribution of Gurland, Chen and Hernandez 1983). We consider, among others, a stochastic formulation (birth-and-death process), the series expansion of the probability distribution and the corresponding series expansion of a generalized exponential distribution (Ong/Lee 1986), and the connection of the NNB distribution with the non-central beta, gamma and non-central gamma distributions. A four-parameter version of the NNB distribution is also presented.     

Industrial Relations Climate in the Manufacturing Sector in Singapore

The objective of this study is to assess the state of workplace industrial relations climate in the manufacturing sector in Singapore. Based on a survey of 73 manufacturing companies in Singapore and subsequent intensive study of eight of them, it was found that the overall labor-management relations in the industry were good and had improved over the past few years. Union membership was reported to have increased and this was accompanied by a perceived increase in union role and influence on labor-management relations. The findings also highlighted the need to strengthen the communication processes among the three parties—workers, unionists and management.     

Annual Review Article 1993: British Public Sector Industrial Relations

Abstract : Developments in public-sector industrial relations during 1993 have raised questions about unions, pay determination and conflict resolution. This review explores some of the tensions in these areas created by new restrictions on pay increases, changes in reward structures and further market-testing across services. Where the different forms of pay determination buy industrial peace, the price may be too high in terms of the productivity and efficiency requirements gains now being demanded. But co-operation is needed too, and the dilution of the Whitley system of collective bargaining may be more likely to produce the very co-operation embodied in its philosophy, but not always present in its practice. The new 'superunion' UNISON will play a role here, as single-table bargaining and even single-union deals develop. These institutional developments will also be affected by pay flexibility measures which endeavour to improve individual performance at the front line of services, while in practice increasingly giving the rewards to management.     

The bivariate non-central negative binomial distributions

Summary Four bivariate generalisations (Type I–IV) of the non-central negative binomial distribution (Ong/Lee) are considered. The Type I generalisation is constructed using the latent structure model scheme (Goodman) while the Type II generalisation arises from a variation of this scheme. The Type III generalisation is formed by using the method of random elements in common (Mardia). The Type IV is an extension of the Type I generalisation. Properties of these bivariate distributions including joint central and factorial moments are discussed; several recurrence formulae of the probabilities are given. An application to the childhood accident data of Mellinger et al. is considered with the precision of the Type I maximum likelihood estimates computed.
