  • Filtering Historical Simulation. Backtest Analysis 

    Giannopoulos, Kostas; Barone-Adesi, Giovanni; Vosper, Les (2000)
    This paper we backtest the FHS VaR model on three types of portfolios invested over a period of two years. The first set of backtests consists of LIFFE financial futures and options contracts traded on LIFFE. In the second ...

  • Non parametric VaR Techniques. Myths and Realities 

    Giannopoulos, Kostas; Barone-Adesi, Giovanni (Wiley Online Library, 2003-12-03)
    VaR (value-at-risk) estimates are currently based on two main techniques: the variance-covariance approach or simulation. Statistical and computational problems affect the reliability of these techniques. We illustrate a ...

  • Backtesting Derivative Portfolios with Filtered Historical Simulation (FHS) 

    Barone-Adesi, Giovanni; Giannopoulos, Kostas; Vosper, Les (European Financial Management, 2002)
    Filtered historical simulation provides the general framework to our backtests of portfolios of derivative securities held by a large sample of financial institutions. We allow for stochastic volatility and exchange rates. ...

  • VaR Modelling on Long Run Horizons 

    Giannopoulos, Kostas (Kluwer Academic Publishers-Plenum Publishers, 2003-07)
    The Value-at-Risk (VaR) criterion as a measure of portfolio's risk on long run horizons is considered. The method which makes possible to generate VaR estimates on longer horizons is suggested. The VaR estimation is based ...

  • Coherent risk measures under filtered historical simulation 

    Giannopoulos, Kostas; Tunaru, Radu (Elsevier, 2005-04)
    Recent studies have strongly criticised conventional VaR models for not providing a coherent risk measure. Acerbi provides the intuition for an entire family of coherent measures of risk known as “spectral risk measures” ...

  • Pricing Basket spread options 

    Giannopoulos, Kostas (Society for Computational Economics, 2006)
    This paper describes and analyses the use of the Filtered Historical Simulation algorithm in pricing spread options. Spread options are contracts whose payoff depends on the price difference (spread) between two or more ...

  • Nonparametric, conditional pricing of higher order multivariate contingent claims 

    Giannopoulos, Kostas (2008-09)
    This paper describes and applies a nonparametric model for pricing multivariate contingent claims. Multivariate contingent claims are contracts whose payoffs depend on the future prices of more than one underlying variable. ...

  • A Market Risk Model for Asymmetric Distributed Series of Return 

    Giannopoulos, Kostas; Nekhili, Ramzi (2012)
    In this paper we propose to model short-term interest rates by taking into consideration both the asymmetric properties of returns, using Pearson’s type IV distribution, and the time-varying volatility, using GARCH models. ...

  • Regional development and non-material public infrastructure 

    Yagi, Tadashi; Vliamos, Spyros (Blackwell Publishers Ltd, 1997)
    The aim of this paper is to investigate the conditions under which public investment can be allocated to the infrastructure in material and non-material capital so as to have a positive effect on regional development and ...

  • An innovative cost – benefit analysis as a decision support system for the evaluation of alternative scenarios of water resources management 

    Aravossis, Konstantin G.; Vliamos, Spyros; Anagnostopoulos, P.; Kungolos, Athanasios (Parlar Scientifc, 2003)
    A crucial problem for planners dealing with the management of water resources is to choose among the available alternative scenarios. In the presented methodology the result is a combination of the data of all the important ...

  • Education Efficiency and Labor Market Achievements: An Evaluation for Twenty OECD Countries 

    Vliamos, Spyros; Tzeremes, Nickolaos G. (Elsevier, 2006)
    The paper uses data envelopment analysis (DEA-CCR model) to evaluate the tertiary-level educational system mechanism, relating a set of inputs to some outputs, in particular, income and employment. The analysis concerns ...

  • Entrepreneurship and innovation at work and schools: The Greek paradigm 

    Vliamos, Spyros (Inderscience Publisher, 2008)
    Rapid technological changes in Global markets today, which require rapid responses of markets, make innovation development a prerequisite. Businesses exploit new ideas to create new products, processes or services and new ...

  • The Assessment of Compensatory Damages for Medical Error by the Greek Courts: An Economic Analysis 

    Vliamos, Spyros; Hatzis, Aristides (Athenian Policy Forum & North Waterloo Academic Press, 2009)
    In this paper, after summarizing and reviewing the methods of computing damages for wrongful death or injury in the law and economics literature, we present the way in which damages should be compensated for according to ...

  • Small business performance: Seeking efficiency through knowledge based networks 

    Vliamos, Spyros; Emm. Halkos, George; G. Tzeremes, Nickolaos (Inderscience Publisher, 2009)
    This paper uses Data Envelopment Analysis (DEA) in order to examine 252 small foreign owned equities operating in the Greek manufacturing sector. By using a number of essential factors (like the number of employees, ...

  • Factors Influencing Entrepreneurial Process and Firm Start-Ups: Evidence from Central Greece 

    Vliamos, Spyros; G. Tzeremes, Nickolaos (Springer, 2012)

  • Optimal long-run inflation and the New Keynesian model 

    Pontiggia, Dario (Elsevier, 2012-08)
    Central banks typically have a long-run inflation target that is modestly positive. However, the standard New Keynesian framework prescribes that zero inflation is the optimal longrun target. In this paper, we show that ...
