    Democracy, Diversification, and Growth Reversals

    There is much evidence that less democratic countries experience more high-frequency growth volatility. In this paper we report a similar finding about volatility in the medium term: we find evidence that reversals of trend-growth are sharper and more frequent in non-democracies. Motivated by this evidence, we construct a model in which non-democracies have high barriers of entry for new firms. This leads to less sectoral diversification and so, in an uncertain environment, to larger growth swings in less democratic countries. We present empirical evidence that confirms the positive relation between democracy and industrial diversification.medium term growth, growth volatility, democracy, diversification

    The Flypaper Effect Revisited

    This paper argues that there is nothing anomalous about the flypaper effect. Idevelop a simple median voter model of government spending with costly taxcollection that predicts the flypaper effect and provide a quantifiable measure of itsmagnitude. Using the model insights and previous estimates, I show that a tax ratebetween 8% to 16% would account for the flypaper effect observed in U.S. subnationalgovernments.flypaper effect, intergovernmental transfers, public finance, fiscaldecentralization

    Consumer behaviour in voice based interactions

    Get PDF
    The following technological trends have occurred in parallel and together positioned and enabled the execution of my research: (a) The field of consumer behaviour that focuses on intuitive judgment and perception biases has developed significantly in recent years, (b) Speech and voice technologies have reached a commercial stage, and (c) The Big Data boom and other proprietary data that are owned by large corporates have located the industry in a better position than traditional academic bodies in terms of research capabilities. These global developments have created the opportunity to conduct this research which aims to explore the relationship between voice and speech attributes and consumer behaviour in the context of telephone based call centre interactions. The access to call centre recordings and their derivative analysis has enhanced this research with the unique experience of a practitioner rather than being limited to an at arm’s length theoretical analysis. The research questions aim to identify voice and speech attributes that affect (positively or negatively) customer satisfaction levels, and ways in which a company can utilize these attributes to change the way its call centre staff operate. The research methodology is based on a qualitative survey through which I collected data from a real-world call centre (auditory observation), and a triangulation of this data with that of a focus group session. The data went through a correlation test through a sample survey and a synthesis that processes the research findings into theoretical, published literature. Following these research insights, I have developed a Hidden Forces Model which is based on the findings arising from the research. This model offers an alternative way to operate call centres considering adjustments in social interaction by the service staff in order to impact and optimise customer satisfaction for the benefit of the company

    Formal Methods Specification and Analysis Guidebook for the Verification of Software and Computer Systems

    Get PDF
    This guidebook, the second of a two-volume series, is intended to facilitate the transfer of formal methods to the avionics and aerospace community. The 1st volume concentrates on administrative and planning issues [NASA-95a], and the second volume focuses on the technical issues involved in applying formal methods to avionics and aerospace software systems. Hereafter, the term "guidebook" refers exclusively to the second volume of the series. The title of this second volume, A Practitioner's Companion, conveys its intent. The guidebook is written primarily for the nonexpert and requires little or no prior experience with formal methods techniques and tools. However, it does attempt to distill some of the more subtle ingredients in the productive application of formal methods. To the extent that it succeeds, those conversant with formal methods will also nd the guidebook useful. The discussion is illustrated through the development of a realistic example, relevant fragments of which appear in each chapter. The guidebook focuses primarily on the use of formal methods for analysis of requirements and high-level design, the stages at which formal methods have been most productively applied. Although much of the discussion applies to low-level design and implementation, the guidebook does not discuss issues involved in the later life cycle application of formal methods
