    Risk and regulation of financial groups and conglomerates

    Recent financial market trends, such as convergence and the spread of conglomerates have changed the nature and structure of the financial sector’s risk profile. The paper investigates this issue from a regulatory policy aspect. Regulatory failures in the 1990s (BCCI, Barings) and the development of the market demonstrate that even „best regulatory practice” does not fulfil the requirements of transparency and efficiency. We investigate the improvement of prudential legislation for financial groups on the example of EU legislation, summarize recommendations made by international forums, and present existing regulatory frameworks in certain countries. In the light of these we address major lacuna in the relevant Hungarian legislation, even going beyond requirements in the field of EU harmonization.financial convergence, financial conglomerates, prudential regulation, European Union, Hungary.

    Risk Premiums and the Storage of Agricultural Commodities

    Get PDF
    The existence of a commodity market risk premium has attracted the interest of researchers for several decades. Most attempts to measure risk premiums have been focused on futures markets. However, if the risk premium is a payment made by hedgers (as suggested by Keynes) to reduce their risk profile, then the risk being reduced originates in the cash market. This suggests that the risk premium may also originate in the cash market. As such, the search for a risk premium should focus on the cash market, and, given Working's Supply of Storage Curve, should be measured as a function of stored inventory. This paper develops an expected utility based model that separates the risk premium from other storage incentives, and illustrates the role of the cash market risk premium on the storage decisions of two different market agents.

    Scenarios for the development of smart grids in the UK: literature review

    Get PDF
    Smart grids are expected to play a central role in any transition to a low-carbon energy future, and much research is currently underway on practically every area of smart grids. However, it is evident that even basic aspects such as theoretical and operational definitions, are yet to be agreed upon and be clearly defined. Some aspects (efficient management of supply, including intermittent supply, two-way communication between the producer and user of electricity, use of IT technology to respond to and manage demand, and ensuring safe and secure electricity distribution) are more commonly accepted than others (such as smart meters) in defining what comprises a smart grid. It is clear that smart grid developments enjoy political and financial support both at UK and EU levels, and from the majority of related industries. The reasons for this vary and include the hope that smart grids will facilitate the achievement of carbon reduction targets, create new employment opportunities, and reduce costs relevant to energy generation (fewer power stations) and distribution (fewer losses and better stability). However, smart grid development depends on additional factors, beyond the energy industry. These relate to issues of public acceptability of relevant technologies and associated risks (e.g. data safety, privacy, cyber security), pricing, competition, and regulation; implying the involvement of a wide range of players such as the industry, regulators and consumers. The above constitute a complex set of variables and actors, and interactions between them. In order to best explore ways of possible deployment of smart grids, the use of scenarios is most adequate, as they can incorporate several parameters and variables into a coherent storyline. Scenarios have been previously used in the context of smart grids, but have traditionally focused on factors such as economic growth or policy evolution. Important additional socio-technical aspects of smart grids emerge from the literature review in this report and therefore need to be incorporated in our scenarios. These can be grouped into four (interlinked) main categories: supply side aspects, demand side aspects, policy and regulation, and technical aspects.

    Social construction of IS evaluation: a case study of IT investment appraisal

    Get PDF
    This study explores the phenomenon of the social construction of IS investment evaluation in the financial services industry. The extensive literature on information systems (IS) evaluation stretches back more than thirty years and it is widely agreed that IS evaluation is an important and complex issue. Constructivist evaluation, which serves to develop the interpretivist strand of the literature, concentrates on the notion that evaluations are the outcomes of an interaction and argumentation process between various interested parties. The purpose of this research is to shed further light on the IS investment evaluation area. Explaining the practice of IS evaluation within the dynamic and technologically sophisticated financial services industry would benefit academics and financial services firms alike. This context is relatively neglected in the existing literature. The chosen case study reflects the demands in the financial services industry to upgrade their infrastructure in order to manage an ever increasing number of transactions, as well as increased regulation. The fieldwork produced extensive data concerning traditional trading, brokerage, high frequency algorithmic trading and transaction clearing. The rapid rise of derivative transactions during the last few years caused problems in terms of clearing and managing the transactions. At the same time, hedge funds‘ growing demand for low latency execution services and changes in regulations increased, pressuring firms in the industry to invest heavily. Actor-network theory (ANT) is used in order to describe and explain the formation of networks between human and non-human actors. The theory‘s specific vocabulary allows IS evaluation to be seen in a new light and the study uses ANT analysis to produce insight into the longstanding problem of IS evaluation, human and non-human interactions and roles within the context if IT investment appraisal. Building on ANT, this thesis is an in-depth case study of the employment process of an IT evaluation method at a global financial services company

    The Cost of Rational Agency

    Get PDF
    The rational agency assumption limits systems to domains of application that have never been observed. Moreover, representing agents as being rational in the sense of maximising utility subject to some well specified constraints renders software systems virtually unscalable. These properties of the rational agency assumption are shown to be unnecessary in representations or analogies of markets. The demonstration starts with an analysis of how the rational agency assumption limits the applicability and scalability of the IBM information filetering economy. An unrestricted specification of the information filtering economy is developed from an analysis of the properties of markets as systems and the implementation of a model based on intelligent agents. This extended information filtering economy modelis used to test the analytical results on the scope for agents to act as intermediaries between human users and information sources
