Research interests
  • The interface between Operational Research and Statistics
  • I have worked recently in efficiency analysis, particularly in the area of Data Envelopment Analysis, where I have developed models for input/output selection, ranking of units, and interpretation of the impact of the presence or absence of an input/output on the final results. This I have applied to the efficiency of bank branches, to the efficiency of microfinance institutions, and to the assessment of insurance risk. More theoretical work in this area involves specialisation versus diversification in the context of efficiency analysis, and models for the assessment of efficiency under centralised management
  • My work in Statistics is mainly in the application of Multivariate Methods to the analysis of social problems. On-going work includes the impact of the right to buy council houses within the social structure of a community; school results within a social context; the application of the methods of optimal scaling to the analysis of Internal Labour Markets in a Spanish railway company in the 19th Century; and structural equation models in the assessment of e-commerce.

    Abstract

    The Co-Plot technique has become stereotyped in the form of a series of steps that are automatically followed with little regard for the characteristics of the data and the type of analysis it supports. While there are obvious extensions to this type of analysis, the methodology has remained unchanged over many years. Here we argue that the application of the Co-Plot to binary, nominal data, as is done in published papers, is inappropriate. We frame the Co-Plot in the general literature of multivariate analysis in order to show that it is a simplification of standard multivariate methods. We use a recently published example on mapping MBA programmes to show how a similar, although more statistically appropriate, analysis based on multidimensional scaling methods produces very different results.

    Abstract

    Microfinance Institutions (MFIs) are special financial institutions. They have both a social nature and a for-profit nature. Their performance has been traditionally measured by means of financial ratios. The paper goes beyond simple financial ratios using a data envelopment analysis (DEA) approach to measure the efficiency of MFIs. Special care is taken in the specification of the DEA model. We take a methodological approach based on multivariate analysis. We rank DEA efficiencies under different models and specifications; e.g. particular sets of inputs and outputs. This serves to explore what is behind a DEA score. The results show that we can explain MFIs efficiency by means of four principal components of efficiency, and this way we are able to understand differences between DEA scores. It is shown that there are country effects on efficiency; and effects that depend on non-governmental organization (NGO)/non-NGO status of the MFI.

    Abstract

    Over 500 job advertisements in the Newsletter of the Operational Research Society are analysed to explore the skills that employers want from students and the tasks that such students are expected to perform in their jobs. There are consequences for the content of Operational Research and Management Science degrees.

    Abstract

    Harmonised aggregate financial statements are published by the European Commission in the BACH database. This information is organised by country, size of firm, and year. Financial ratios obtained from this database are analysed using multivariate statistical techniques in order to explore country and size effects. The data relates to three size groups, eleven countries, fourteen years, and fifteen financial and economic ratios. It is found that ratios reflect the size of the firm, but that the way in which this is reflected varies between the different countries. It is also found that there are no significant size related differences in financial profitability, but that such differences appear when countries are compared

    Abstract

    This paper uses Data Envelopment Analysis (DEA), a non-parametric approach to the estimation of production functions, in order to assess efficiency in dot com firms. These firms have two objectives: to make an impact in the Internet and to obtain revenues from their activities. For this reason, the outputs have been two: unique visitors?a web metric?and revenues. DEA efficiencies have been obtained under various input/output combinations. A ranking of dot com firms in terms of relative efficiency has been obtained. A method based on multivariate analysis has been proven to be successful at showing the strengths and weaknesses of individual dot com firms. It is shown that there is a relationship between the type of e-business (e-tailers, search/portal, content/communities), and the way in which efficiency is obtained. The paper suggests a new approach to the problem of deciding which inputs and outputs the model should contain.

    Abstract

    This paper discusses the identification and measurement of intangible assets in the public sector. A discussion of intellectual capital theory identifies and classifies a number of intangible assets of relevance to the public sector. Multidimensional scaling and related multivariate techniques are proposed for their detection and quantification. The methodology is illustrated with a case study: the provision of council services through the Internet by Spanish municipalities. The technique identifies three intangible assets related to external structural capital: service, image and transparency. Five strategic groups reveal the different objectives, strategic use of the Internet, and actions taken by the various Spanish councils

    Abstract

    "Develops a model for efficiency for the case of joint production functions. This is the first DEA model in quadratic programming formulation. There is much research going on that uses it, but little has been published as now, since there is no standard so"
