Purpose Compulsory airtightness testing was introduced for new dwellings in England and Wales in 2006 and in Scotland in 2010 to ensure that they are constructed according to design air permeability targets. These targets are set to limit heat loss through air infiltration. Previous work examining the large Air Tightness Testing and Measurement Association (ATTMA) data set of UK airtightness test data suggested that, in a proportion of dwellings, the targets were being met by post-completion sealing as opposed to airtight construction, but did not quantify the prevalence of this practice. The paper aims to discuss this issue. Design/methodology/approach In this paper, the distribution of as-built airtightness and the proportion of dwellings undergoing post-completion sealing are estimated from the ATTMA data set covering 2015–2016. This is carried out by Bayesian statistical modelling, using the data set of recorded test results and a modelled representation of the testing process. Findings This analysis finds the mode of the as-built distribution of air permeability as 4.38 ± 0.01 m3/m2h. It predicts that 39 per cent of dwellings aiming for one of the five most common design targets have sealing interventions at the point of pressure testing to meet their target. The as-built distribution of the ATTMA data is compared to airtightness test data obtained from just before compulsory testing was introduced, showing an improvement in the modal air permeability of 3.6 m3/m2h since testing became mandatory. Originality/value This paper has investigated the available data beyond simply what is reported, to estimate what the real levels of airtightness in the UK new build stock may be.

Purpose The purpose of this paper is to investigate the extent to which rewards-based crowdfunding really does provide financial support for start-ups and small businesses relative to other types of activity such as creative and cultural projects. Design/methodology/approach The paper reports findings from a series of multiple regression on a unique data set covering around 205,000 rewards-based crowdfunding projects across a number of leading platforms in the USA, the UK and Canada. Findings The authors report two main findings. First, rewards-based crowdfunding is highly inequitably distributed and that success is concentrated within a relatively small number of platforms and campaigns. Second, crowdfunding campaigns explicitly related to business perform relatively poorly compared with those in other categories; particularly those in creative areas such as music and dance. Originality/value These findings call into question the extent to which rewards-based crowdfunding really is a means by which significant numbers of start-ups can bridge gaps in the provision of finance.

PurposeIn the UK, the vast majority of university students specialise and study just one subject at bachelor degree level, commonly known in the UK as a single honours degree. However, nearly all British universities will permit students if they wish to study two or even three subjects, so-called joint or combined honours degrees, internationally known as a double major. The purpose of this paper is to explore whether the study of a joint rather than a single honours degree had an impact on employment outcomes six months after graduation.Design/methodology/approachThe authors analysed the complete data set provided from the Higher Education Statistics Agency Destination of Leavers from the Higher Education survey. The data were analysed to establish whether there was a difference in the highly skilled graduate employability of the joint honours students. The authors established whether there were any differences inherent in completing a joint honours degree in a post-1992 higher education institution, by nation within the UK or within a Russell Group higher education institution.FindingsThe authors found an approximately consistent 3 per cent point negative gap nationally in the highly skilled employment rates of joint compared with single honours graduates. This gap was at its lowest in the highly selective Russell Group universities (−1.52 per cent points) and highest in post-1992, vocationally oriented universities (−7.13 per cent points) and in Northern Ireland universities (−12.45 per cent points). Joint honours graduates of Scottish universities fared well, with a +3.09 per cent point advantage over the national average for joint honours. The authors found that universities that had a higher proportion of joint honours graduates generally had a lower employability gap between their joint and single honours graduates.Research limitations/implicationsThis study focussed on joint honours degrees in the UK where the two or three principal subjects fall into different JACS subject areas, i.e. the two or three subjects are necessarily diverse rather than academically cognate. Future work will consider the class of joint honours degrees where the principal subjects lie within the same JACS subject area, i.e. they may be closer academically, although still taught by different academic teams. This grouping will include, for example, pairs of foreign languages, some social sciences pairings such as politics and sociology, and pairings such as history and theology from the historical and philosophical subject area.Originality/valueThe potential disbenefits of studying for a joint honours degree are apparent in this study. Joint honours students may face organisational, academic and cultural challenges that require a positive, conscious and sustained effort to overcome, on both the part of the student and the higher education institution. In particular for graduates of the post-1992 universities, it appears that there is a negative relative impact on highly skilled employment. This impact is lessened if the university is Scottish (four-year degrees with in-built breadth of study) or where the proportion completing joint honours degrees is relatively high.

Purpose This study aims to inquire about pre-requisites and benefits of collaboration in the UK and India, testing for significance of country context. Design/methodology/approach The survey data set includes 118 UK-based and 175 India-based small and medium enterprises (SMEs). This paper applies a grounded theory research design, given that to date, no sufficient SME sector-specific, quantitative frameworks have been published. Findings India-based SMEs are more inclined towards frequent collaboration. Soft variables such as perceived trustworthiness or past commitment, appear to be significant when explaining whether or not SMEs in India enter into a collaboration. Operations-driven motives play the most significant role for them, whereas for UK-based SMEs, product design-related collaboration motives are of more importance. Research limitations/implications The developed cross-country and country-specific collaboration variables will facilitate SME studies under a consistent and complete framework. Practical implications Business associations and SME owners in the UK can use the research to gain an Indian perspective and vice versa. This study concludes a stylised framework for SME owners and managers to classify collaboration patterns in a country. Originality/value While previous research established concepts and practices of SME collaboration, this is the first paper that quantitatively addresses the attitudes and experiences that SME owners hold when initialising inter-firm collaboration.

Purpose By building on cooperation–competition theory, this study aims to investigate the multidimensional flipped effects of neighborhood hotels on Airbnb listings’ popularity, examining the degree to which such impacts are influenced by hotel types and geographical areas. Design/methodology/approach This study explores the interdependent and competitive relationship between neighborhood hotels and Airbnb from the perspective of effects on Airbnb listings’ popularity by exploring a data set covering 10,492 Airbnb listings and 2,691 hotels from Ctrip. Findings Results reveal that neighborhood hotels’ number of reviews, review ratings and prices each have positive spillover effects on Airbnb listings’ popularity, while quality assurance labels and negative review topic sentiments exert competitive effects on Airbnb popularity. Moreover, the number of budget chain hotels and high-star hotels have positive and negative effects on Airbnb popularity, respectively. Geographical areas also have a moderating effect on the relationship between various hotel-related influencing factors and Airbnb. Practical implications This study can offer hotel managers and Airbnb operators a clearer understanding of these businesses’ coexisting relationship. Findings can also provide Airbnb-specific guidelines for practitioners in terms of site selection, promotional features and development strategies for Airbnb listings. Originality/value This study establishes a cooperation–competition relationship model between hotels and Airbnb and considers the flipped effects of hotels on Airbnb for the first time. It expands previous studies by considering the multidimensional effects of hotels on Airbnb listings’ popularity and by examining the influences of hotel types and geographical areas on hotels’ impacts on Airbnb.

PurposeThe purpose of this study is to first assess how the US healthcare financing system is influenced by income variation. Then, it examines whether or not the impact of income variation is asymmetric.Design/methodology/approachFor the analyses of this paper, the autoregressive distributed lag (ARDL) model is implemented to a data set covering the period from 1960 to 2018.FindingsThe results provide evidence that major funding sources of aggregate healthcare expenditure (HCE) respond differently to changes in income. The results also imply that the effect of income is not always symmetric.Originality/valueMany studies have attempted to identify the relationship between income and HCE. A common feature of past studies is that they have only focused on aggregate HCE, while one might be interested in knowing how major funders of aggregate HCE would be affected by changes in income. Another common feature of past studies is that they have assumed that the relationship between income and HCE is symmetric.

Purpose This paper aims to analyse normative corporate governance evolution in the UK between 1995 and 2014 against the benchmark of Organisation for Economic Co-Operation and Development (OECD) regulatory principles. Design/methodology/approach Methodologically, the authors conduct an empirical, longitudinal data set analysis of the formative years of UK normative corporate governance development between 1995 and 2014. We provide a qualitative discussion of the empirical evidence that links the type of UK regulatory corporate governance development to financial market growth thereby adopting a mixed approach based on quantitative and qualitative research methods. Findings The authors find that compared to the OECD model of corporate governance, the UK model is less rigid following a more self-regulatory approach based upon a “comply or explain” paradigm. Thus it is scored below corporate governance systems that follow a compulsory implementation model. However, even with such “low” tilt towards formal shareholder primacy norms, the UK has the best performing financial market. As a quasi-empirical study, the authors suggest that there are several historical and economic reasons for this, which together with a robust rule of law in the UK contribute to this performance – and the law especially the type or tilt is less relevant. Originality/value This is the first of its kind empirical, longitudinal data set analysis with qualitative elements that links empirical evidence to regulatory developments in the wider context of UK corporate governance evolution.

Purpose Despite the scholarly attention for the integration of sustainability within business strategy and processes, little is known about how strategic orientations of companies influence this integration. Drawing on stewardship theory, this paper aims to analyse the influence of strategic orientation of companies on their environmental, social and corporate governance (ESG) performance and the moderating effect of three different political models of economy (Rhine, British and American). Design/methodology/approach This paper creates a measurement for strategic orientations by using a coding scheme with a five-category evaluation matrix. The main empirical analysis is done by a fixed-effect model with a panel data set covering 179 publicly traded companies over the 2009-2016 period. Findings The conclusions of this paper present that – consistent over time – a stronger orientation on stewardship positively associates with higher ESG performance. Additionally, the political model of economy significantly alters the relationship indicating the effect of strategic orientation on ESG performance. The relationship is significantly stronger in the Rhine model and significantly weaker in the British model, when both compared to the American model. Originality/value The implications of this paper are vital to understanding corporate strategic orientation and its relationship to actual corporate behaviour and long-term performance. Implementing the elements of focus, motivation, commitment, support and communication linked to a stewardship orientation is fundamental to achieve higher levels of sustainability performance.

Purpose In today’s global economy, high in talent but low in growth, the capability and skills mismatch between the output of universities and the demands of business has escalated to a worrying extent for graduates. Increasingly, university students are considering alternatives to a lifetime of employment, including their own start-up, and becoming an entrepreneur. The literature indicates a significant disconnect between the role and value of education and healthy enterprising economies, with many less-educated economies growing faster than more knowledgeable ones. Moreover, theory concerning the entrepreneurial pipeline and entrepreneurial ecosystems is applied to graduate entrepreneurial intentions and aspirations. The paper aims to discuss these issues. Design/methodology/approach Using a large-scale online quantitative survey, this study explores graduate “entrepreneurial intention” in the UK and France, taking into consideration personal, social and situational factors. The results point to a number of factors that contribute to entrepreneurial intention including social background, parental occupation, gender, subject of study and nationality. The study furthers the understanding of and contributes to the extant literature on graduate entrepreneurship. It provides an original insight into a topical and contemporary issue, raising a number of research questions for future study. Findings For too long, students have been educated to be employees, not entrepreneurs. The study points strongly to the fact that today’s students have both willingness and intention to become entrepreneurs. However, the range of pedagogical and curriculum content does not correspond with the ambition of those who wish to develop entrepreneurial skills. There is an urgent need for directors of higher education and pedagogues to rethink their education offer in order to create a generation of entrepreneurs for tomorrow’s business world. The challenge will be to integrate two key considerations: how to create a business idea and how to make it happen practically and theoretically. Clearly, change in the education product will necessitate change in the HE business model. Research limitations/implications The data set collected was extensive (c3500), with a focus on France and the UK. More business, engineering and technology students completed the survey than others. Further research is being undertaken to look at other countries (and continents) to test the value of extrapolation of findings. Initial results parallel those described in this paper. Practical implications Some things can be taught, others need nurturing. Entrepreneurship involves a complex set of processes which engender individual development, and are highly personalised. Higher Education Enterprise and Teaching and Learning Strategies need to be cognisant of this, and to develop innovative and appropriate curricula, including assessment, which reflects the importance of the process as much as that of the destination. Social implications The global economy, propelled by the push and pull of technology, is changing at a speed never before seen. This is having profound political, social and economic effects which necessitate fundamental change that we organise ourselves and our activities. Current models and modus operandi are proving increasingly unfit for purpose. Nurturing and encouraging agile mindsets, creativity, supporting the testing of new ideas and ways of doing things and adapting/adopting to innovation are all critical future employability factors. Our future prosperity and well-being will be dependent on creating new learning models. Originality/value This work builds on an extensive literature review coupled with original primary research. The authors originate from a variety of backgrounds and disciplines, and the result is a very challenging set of thoughts, comments and suggestions that are relevant to all higher education institutions, at policy, strategy and operational levels.

Purpose – This paper aims to distinguish whether the decision-making process of the Islamic financial houses in the UK can be improved through the use of credit scoring modeling techniques as opposed to the currently used judgmental approaches. Subsidiary aims are to identify how scoring models can reclassify accepted applicants who later are considered as having bad credit and how many of the rejected applicants are later considered as having good credit, and highlight significant variables that are crucial in terms of accepting and rejecting applicants, which can further aid the decision-making process. Design/methodology/approach – A real data set of 487 applicants is used consisting of 336 accepted credit applications and 151 rejected credit applications made to an Islamic finance house in the UK. To build the proposed scoring models, the data set is divided into training and hold-out subsets. The training subset is used to build the scoring models, and the hold-out subset is used to test the predictive capabilities of the scoring models. Seventy per cent of the overall applicants will be used for the training subset, and 30 per cent will be used for the testing subset. Three statistical modeling techniques, namely, discriminant analysis, logistic regression (LR) and multilayer perceptron (MP) neural network, are used to build the proposed scoring models. Findings – The findings reveal that the LR model has the highest correct classification (CC) rate in the training subset, whereas MP outperforms other techniques and has the highest CC rate in the hold-out subset. MP also outperforms other techniques in terms of predicting the rejected credit applications and has the lowest misclassification cost above other techniques. In addition, results from MP models show that monthly expenses, age and marital status are identified as the key factors affecting the decision-making process. Originality/value – This contribution is the first to apply credit scoring modeling techniques in Islamic finance. Also in building a scoring model, the authors' application applies a different approach by using accepted and rejected credit applications instead of good and bad credit histories. This identifies opportunity costs of misclassifying credit applications as rejected.

Purpose This paper aims to empirically investigate the impact of bank diversification on performance and risk-taking behavior. The analysis uses an unbalanced panel data set covering the period between 2007 and 2015 for a total of 1,397 banks from ASEAN-5 and BRICS economies. Design/methodology/approach Dynamic panel generalized method of moments (GMM) has been used primarily to examine the relationship between bank diversification on performance and risk-taking and later, validate the core results by incorporating two-stage least squares (2SLS). Findings Similar to the results of previous studies based on the developed economy, this study also confirms the hypothesis of the portfolio diversification. The key robust result is that the benefits from revenue and assets diversification are heterogeneous and the BRICS banks achieve higher benefit from using both diversification strategies. On the other hand, ASEAN-5 banks fail to show the significant advantage from assets diversification. Among the diverse sources of income, interest is not a major determinant of efficiency and bank’s stability, while ASEAN-5 banks should foster commission and others income as mechanisms for diversification benefit in the region. Originality/value A few studies are available in the current literature which examines the impact of revenue and assets diversification on either bank performance or risk-taking in the developed economy’s context. However, very few studies are found that examine the relationship between bank diversification, performance and risk-taking together. Moreover, to the best of the author’s knowledge, there is a dearth of literature on this topic that built on the comparative analysis between two regions, i.e. ASEAN-5 and BRICS. As a result, the empirical results of this research provide useful information to the stakeholders so that they can enhance bank diversification strategy and implement them successfully by considering the other factors.
