Innovation performance and the role of clustering at the local enterprise level: a fuzzy-set qualitative comparative analysis approach

ABSTRACT

This study, utilizes an innovative methodological approach, fuzzy-set Qualitative Comparative Analysis (fsQCA), investigating the drivers of heterogeneous geographies characterizing English Local Economic Partnerships (LEPs). The fsQCA technique offers a novel configurational alternative to regression-based approaches investigating the effects of clustering in conjunction with firm-level innovation, university third-sector activity (TSA) and entrepreneurship, on LEPs innovation performance. The findings, offer contributions to the theories of industrial clusters and innovation, regional innovation systems, knowledge spillovers and entrepreneurial university innovation within LEPs. First, supporting fsQCAs, no individual variable generates either a positive/negative innovation outcome. Second, while all positive innovation recipes include presence of the cluster variable, for negative innovation recipes, only one does not identify absence of clustering as relevant. Given that the cluster variable does not appear in any recipes without at least one of the other variables suggests activity concentration does not exist in isolation to generate innovation outcomes without other localized conditions existing, e.g. firm-level innovation. Third, there is evidence for the non-cluster-based aspects of knowledge spillover theory of entrepreneurship with respect to university activity and the entrepreneurial university concept. Instead, roles of entrepreneurship and university TSA, while important, appear to be more peripheral and geographically context specific.     

Contract length heterogeneity and the persistence of monetary shocks in a dynamic generalized Taylor economy

We develop the generalized Taylor economy (GTE) in which there are many sectors with overlapping contracts of different lengths. In economies with the same average contract length, monetary shocks will be more persistent when longer contracts are present. Using the Bils–Klenow distribution of contract lengths, we find that the corresponding GTE tracks the U.S. data well. When we choose a GTE with the same distribution of completed contract lengths as the Calvo, the economies behave in a similar manner.     

On the ‘Steady State’ Properties of Financial Ratios

This paper uses the methods of continuous time stochastic calculus to investigate the ‘steady state’ properties of financial ratios. Basing our analysis on previous work in the area, we show that, if a financial ratio can be characterised as a diffusion process which possesses an asymptotic equilibrium, then the Fokker-Kolmogorov-Planck forward equation may be used to ‘retrieve’ its probability density. The approach is ‘flexible’ enough to incorporate a wide variety of density functions, many of which have not been investigated in the literature. We demonstrate the procedures which may be used to derive both the cross-sectional and time series tests implied by these distributions. The paper also includes a section dealing with the methods which may be used for parameter estimation, once the underlying distribution has been determined.     

Dilemmas in the management of temporary work agency staff

Temporary jobs account for an increasing proportion of new engagements in the UK labour market, with temporary work agencies or 'labour market intermediaries' occupying a central role in the regulation of entry into some organisations. Such evolving arrangements have been found to have their contradictions, even for the host organisation. This article explores the internal and external pressures to use a temporary work agency as a means of recruiting labour at host organisations. It considers some of the HRM issues that stem from the use of such workers, including the tendency to devolve HRM to the managers of such agencies operating within the host organisation. Central to this article is a consideration of the potential sustainability of organisations' use of temporary agency workers, engaging with this concern from the perspective of organisational cost‐effectiveness.     

ω‐Homothetic Preferences: Theory and Applications

This paper develops a new class of homothetic preferences which generate Marshallian demand curves for individual goods which can be concave, convex or linear in own price under the assumption that agents treat aggregate price indices as given (as in Dixit‐Stiglitz, 1977). The preferences are represented by a cost function which has two parameters: one determining the curvature of the Marshallian demand; the other determining the elasticity of demand when all prices are equal. The elasticity of demand varies with relative prices. Illustrative examples are given of Cournot duopoly and exchange rate pass‐through.     

INTEGER PRICING AND BERTRAND-EDGEWORTH OLIGOPOLY WITH STRICTLY CONVEX COSTS: IS IT WORTH MORE THAN A PENNY?

In this paper we analyse the implications of integer pricing for Bertrand Edgeworth oligopoly with strictly convex costs. When price is a continuous variable, there is a generic non-existence of pure-strategy equilibrium. In the case of integer pricing, this is not so. We characterize a set of possible single price equilibria around the competitive price, which if non-empty will constitute the set of single price equilibria if the industry is large enough. Furthermore, we provide an example in which the highest equilibrium price can be arbitrarily far from the competitive price.     

PSYCHOLOGICAL CONTRACTS AND JOB SATISFACTION: CLUSTERING ANALYSIS USING EVIDENTIAL C‐MEANS AND COMPARISON WITH OTHER TECHNIQUES

The psychological contract refers to an individual employee's belief in mutual obligations between them and their employer. Psychological contracts are a key management concern, as they can impact employees' attitudes and behaviors in ways that influence organizational efficiency and effectiveness. In this paper, we analyse the relationship between the psychological contract and facets of job satisfaction among non‐profit sector employees, using the nascent non‐hierarchical evidential c‐means (ECM) clustering technique. To date, this technique has been theoretically discussed but not widely applied. Based on the Dempster–Shafer theory of evidence, ECM is novel in facilitating the assignment of objects, not only to single clusters, but to sets of clusters, and no clusters (outliers). The paper compares the theoretical underpinnings and findings from ECM with those of three other well‐known clustering techniques, namely (1) the hierarchical Ward's method, (2) the non‐hierarchical crisp k‐means and (3) the non‐hierarchical fuzzy c‐means approaches. We present and interpret the cluster solutions from each clustering technique. We establish three clusters differentiated by the content of the employees' psychological contracts. These clusters are validated by considering their relationship with facets of job satisfaction, to ensure the clusters are theoretically meaningful. Comparisons of the findings from each technique: (1) provide insights into the relationship between the psychological contract and job satisfaction; (2) reveal what ECM encompasses, relative to other clustering techniques; (3) inform the selection of an appropriate clustering technique for a specific research problem; and (4) demonstrate potential future directions in the development of cluster analysis.

China as a Global Manufacturing Powerhouse： Strategic Considerations and Structural Adjustment

This study examines the nature and consequences of China＇s rise to the center of world economic affairs through manufacturing-led development. Our historical analysis shows that China is still well short of the point in its developmental process where its growth might be reasonably expected to slow, or the energy, resource and carbon intensity of growth to recede. The study argues that the current trajectory of industrialization will have to be altered when China becomes more actively engaged in dealing with structural issues at home and abroad against the background of the unwinding of global imbalances. One profitable strategy that China might employ wouM be to approximate the incredibly fruitful mass-market integration efforts of the USA that eventually elevated it to its position of global primacy. The cyclical re-emergence of excess capacity in Chinese heavy industry, serious questions about the medium term ability of other major regions to accommodate further large gains in Chinese market share, and the stark conflict between the contemporary style of industrial development and the health of the biosphere indicate strongly that now is the time to catalyze the required adjustment and reform processes that will underpin sustainable long-run prosperity.
