Unit Root Testing under a Local Break in Trend using Partial Information on the Break Date*

We consider unit root testing allowing for a break in trend when partial information is available regarding the location of the break date. This takes the form of knowledge of a relatively narrow window of data within which the break takes place, should it occur at all. For such circumstances, we suggest employing a union of rejections strategy, which combines a unit root test that allows for a trend break somewhere within the window with a unit root test that makes no allowance for a trend break. Asymptotic and finite sample evidence shows that our suggested strategy works well, provided that, when a break does occur, the partial information is correct. An empirical application to UK interest rate data containing the 1973 ‘oil shock’ is also considered.     

'Men of small standing'? Locating accountants in English society during the mid-nineteenth century

The census enumerators' books for three counties in 1851 are utilized to explore the social standing of accountants in early-Victorian England. The objective is to illuminate sources of differential status within the occupation of accountancy and thereby enhance understandings of the problems of boundary definition and closure which confronted those who organized the profession in England from 1870. It is shown that accountants occupied various strata in local social structures, from the professional class to the pauper. Accountants were, however, predominantly positioned on the margins of the middle class and very few of their number exhibited styles of living which contemporaries identified as characteristic of professional men. The findings confirm that the term 'accountant' encompassed a wide range of occupational experiences and employment statuses and its meaning appears to have been subject to spatial variation.     

Supply and demand of policy indicators

The aim of this article is to question the idea that all professional service organizations are undergoing a process of inter-archetype transformation. This idea, originating in organizational archetype theory, is now being used to interpret contemporary processes of change in British and other public sector services. Drawing on an example of management UK restructuring in social services during the 1990s – that of local authority social services in the UK – two main problems with this thesis are identified. First, this service demonstrates that ‘radical’ change has not occurred and that older professional values and working practices persist. Second, it reveals how, in at least one part of the public sector in the UK, management reforms have been partly undermined by a specific constellation of institutions and practices. These observations call for questioning the proposition that inter-archetype change is what has occurred and that current reforms will inevitably have this sort of transformational effect.     

Leadership for Collaboration

Abstract

‘Leadership’ and ‘collaboration’ are integral to twenty-first century governance and management but, despite a growing literature, understanding about leadership for collaboration is hampered by a lack of specificity and nuance in theory and empirical research. This article responds to these limitations by working within an interpretive framework and employing Q-method to uncover different interpretations of leadership for collaboration operant among public managers in Wales. The article uses the concept of situated agency to explain why public managers offer diverse interpretations of leadership for collaboration despite working within the same governance framework, and to identify challenges to public managers in determining appropriate leadership for collaboration.     

Human capital enhancing HRM systems and frontline employees in Australian manufacturing SMEs

The current study seeks to answer a number of key questions concerning the strategic management of frontline employees (e.g. individuals who do not occupy an executive, managerial or supervisory role in functions such as production, maintenance, service and clerical functions) and their contributions towards the performance of small- and medium-sized manufacturing firms in Australia. This study adopts a human capital perspective to examine the employee and organisational performance of small and medium enterprises (SMEs) in Australia. We were also interested in seeking to examine the presence of the human resource management (HRM) function of SMEs in Australia and their contribution towards employee and firm performance. Findings from the partial least square analysis identified the antecedents and consequences of a human capital enhancing (HCE) approach for the strategic HRM of frontline employees in Australia's manufacturing industry. Strategic orientations of small- and medium-sized manufacturing firms mediate the contribution of the HRM function in adopting a set of HCE HRM systems. HCE HRM system was found to have a direct and indirect impact on manufacturing performance outcomes. Frontline employees' performance was found to mediate the impact of HCE HRM system on manufacturing performance outcomes. Theoretical and practical implications are discussed in relation to the management of frontline employees in enhancing perceived employee and manufacturing performance.     

COEFFICIENT CHANGE,PRICE EFFECTS,AND IMPLICIT ELASTICITIES: ESTIMATING MICROECONOMIC DETERMINANTS OVER TWO TIME PERIODS

This paper presents and estimates an input–output model in which input coefficient changes are functions of changing prices. The model produces results that mirror the characteristics of input demand functions based on the model of cost minimization subject to producing a desired level of output. It does not rely on the specification of a functional form for input coefficients, and it does not require the use of assumptions regarding the elasticity of substitution. Instead, it allows the actual price and coefficient changes that occur between periods to identify the implicit elasticities and own- and cross-price derivatives. Using this model, it is shown how accurate measures of price effects, including the full array of own and cross-elasticities of demand, can be estimated for models comprising up to 15 sectors given data for only two time periods.     

Reconciling Gray and Hotelling

A bstract .   Early exhaustible resource economics provides an important foundation for recent suggestions that firm-level economic modeling plays a larger role in the analysis of resource scarcity. The lack of empirical support for Hotelling's r -percent rule, introduced in 1931, and recent suggestions that industry behavior may not be reducible to firm behaviors are the primary motivating factors for examining the relative value of Gray's contribution to the field of exhaustible resource economics relative to Hotelling's contribution. Specifically, Gray's papers that appeared in the 1910s provide insight into the heterogeneity of deposits and their spatial dimensions, and offer the possibility that firms will be subject to fixed costs carried over between periods. In this paper, the arguments presented by Gray are formalized in a dynamic model, which allows the differences between Gray's and Hotelling's assumptions to be more fully explored. The results of the paper illustrate that by considering spatially identifiable heterogeneous deposits, fixed costs, and entry costs, in general Hotelling's r -percent rule is not a sufficient condition for firm-level decision making and that firms' extraction behavior cannot be linearly aggregated to describe industry behavior.
