Abandoning internal and external validity: A response to Swanborn

This is a reply to Peter Swanborn's comments on my paper A note on Campbell's distinction between internal and external validity. I argue that Swanborn misconstrues my argument, interpreting it as recommending the abandonment of the concept of external validity, whereas it actually proposed abolition of thedistinction between internal and external validity. I also explain that my argument did not involve a denial of the importance of the various issues included under these headings by Campbell, merely a proposed reconceptualisation of them.     

A comparative study of the contents of personnel and human resource management textbooks

The paper reports the results of a contents analysis performed on fifty personnel and HRM texts. It suggests that there is a common set of person-nel/HRM tasks across cultures. Within this common set there are differences in the priority accorded to particular tasks. British HRM texts give priority to organizational theory, American HRM texts prioritize corporate strategy, while personnel texts prioritize industrial relations and collective bargaining. The conclusion considers as possible explanations the divergence in the systems of industrial relations of the two countries and the markets towards which the texts are oriented. It argues that a more likely explanation derives from the differential cultural values which inform managerial research in Britain and America.     

Advertising in demand systems: testing a Galbraithian hypothesis

In this paper we argue that the influence of advertising upon the inter-product distribution of demand is a system-wide phenomenon which is investigated better through a demand equation system rather than through single equation methods. Attention is focused upon a dynamic version of Deaton Muellbauer's AIDS model modified to include advertising terms. Within this framework using data on consumer's non-durable expenditure in the UK we carry out a preliminary test of Galbraith' hypothesis that advertising may affect the composition of aggregate consumer demand.     

Impacts on travel behaviour of Greater Manchester’s light rail investment (Metrolink Phase 1): evidence from household surveys and Census data

Household survey data from 1990 and 1993 and Census data from 1991 and 2001 are used to detect some short and medium term impacts on travel of the Metrolink light rail services which opened in 1992. Particular attention is paid to research design issues to try to isolate Metrolink’s impacts from those of other influences on travel behaviour. In the short term a more marked decline in the frequency of bus use is found in the Metrolink corridor compared with conventional rail and ‘no rail’ corridors. Changes in the frequency of rail use are more prominent in the Metrolink corridor, both to the highest frequency use but also to lower frequency use. Higher frequency rail use tends to be associated with respondents who have limited or no car availability, who are in employment, who are of non-manual social class and who are aged 18–44 years. Metrolink appears to have attracted at least as many former car users as former bus users, but the former car users tend to use the light rail services less frequently. Census commuting data suggest that, in the medium term, Metrolink has increased rail’s share of trips, especially to the city centre, contributed to the declining share of bus trips and may have helped to restrain work trips by car.     

The Bases of Compromise in the Workplace: A Theoretical Framework

Schemes for workplace participation have long been promoted and vilified. Such conflicting views have been brought into sharp focus by the highly variable results of such practices as teamwork. Yet a theoretical framework to grasp workplace co‐operation is lacking. This paper develops a framework on the basis of theory and a review of a wide range of empirical studies. Capital and labour each have two sets of ‘concerns’: over ‘control’ of the workplace and the longer term ‘development’ of the productive forces. Cross‐classifying these concerns produces a matrix of patterns of workplace relations. Each cell of the matrix represents a different combination of the interests of capital and labour. The matrix can be used to map participation schemes so as to capture their varying features. The next task, pursued elsewhere, is to identify the conditions leading to locations in different cells of the matrix.     

The takeover and selection effects of foreign-owned establishments: an analysis using linked employer–employee data

We provide the first estimates of the effect of foreign ownership on wages in Germany, controlling for the observed and unobserved characteristics of workers and plants. We also test whether the wage gains from joining a foreign-owned firm are subsequently lost when leaving that firm, and we examine whether wage gains vary across the sample. We find large selection effects in terms of worker and plant components of wages. Once the selection effect is taken into account, the takeover effect is small and in some cases insignificantly different from zero.

Tobacco consumption and policy in the United Kingdom

In recent years, several structural changes and sequences of shocks have occurred in the market for tobacco in the UK, including an explosive growth in smuggling. This study examines whether it is still possible to estimate a reliable, plausible tobacco demand equation from time series data for the UK whilst allowing for all of the various shocks and structural changes. A second objective of this study is to use the estimated demand function to evaluate tobacco policy in the UK, including the scope for using tax increases to achieve reduced consumption and increased revenues. It is found that smuggling has diminished the revenue yield of higher rates of duty, but total consumption of tobacco has been reduced. In addition to the introduction of further measures to control smuggling, policy may need to place more emphasis in the future on health campaigns and smoking restrictions.     

THE RELATIONSHIP BETWEEN UNEMPLOYMENT AND UNFILLED VACANCIES IN GREAT BRITAIN: AN EXTENDED JOB-SEARCH, LABOUR TURNOVER VIEW

This paper develops a model of the equilibrium unemploymentvacancy relationship, drawing upon concepts in the job searchlabour turnover literature, and uses that model to explain recent shifts in the uv curve for Great Britain. The analysis involves two stages: the estimation of a dynamic employment adjustment equation, and then the solution of the estimated form for the implicit, equilibrium uv relationship at different points in time. In this approach it is possible to attribute shifts in the uv curve to various exogenous factors such as the movement in real wages relative to productivity, external competitiveness, mismatching between jobs and workers, and the replacement ratio.
