  • Endogenous contagion – a panel data analysis 

    Baur, Dirk; Fry, Renee (CFAP, Cambridge Judge Business School, University of Cambridge, 2006)
    This paper proposes a panel data model to analyze contagion in a multivariate framework. The model distinguishes between vulnerability and contagion, and provides a time series of contagion. The most important feature of ...

  • Can Feedback Traders Rock the Markets? A Logistic Tale of Persistence and Chaos 

    Tambakis, Demosthenes N (CFAP, Cambridge Judge Business School, University of Cambridge, 2006-03)
    This paper introduces a nonlinear feedback trading model at high frequency. All price adjustment is endogenous, driven by asset return and volatility in the previous trading period. There is no stochastic uncertainty or ...

  • Lawless Privatization? 

    Medova, Elena; Tischenko, Larissa (CFAP, Cambridge Judge Business School, University of Cambridge, 2006)
    This paper provides an historical analysis of the four privatization stages of the Russian economy covering the period 1986-2005 with particular attention to the initial period of private capital formation. We use data ...

  • Venture Capital Fund Performance and the IPO Market 

    McKenzie, Michael; Janeway, William (CFAP, Cambridge Judge Business School, University of Cambridge, 2008)
    In this paper, the investment performance of a large database of venture funds is considered over a 28 year period. The results suggest that a portfolio of venture capital partnerships can provide an average return that ...

  • Global Rebalancing: US Protection versus Europe-led reflation 

    Irvin, George; Izurieta, Alex (CFAP, Cambridge Judge Business School, University of Cambridge, 2006)

  • New Evidence on Taxes and Portfolio Choices 

    Alan, Sule; Atalay, Kadir; Crossley, Thomas F.; Jeon, Sung-Hee (CFAP, Cambridge Judge Business School, University of Cambridge, 2009-05)
    Identifying the effect of differential taxation on portfolio allocation requires exogenous variation in marginal tax rates. Marginal tax rates vary with income, but income surely affects portfolio choice directly. In systems ...

  • Technological roots and structural implications of the double bubble at the turn of the Century 

    Perez, Carlota (CFAP, Cambridge Judge Business School, University of Cambridge, 2009-04)
    This paper argues that the two boom and bust episodes of the turn of the Century – the Internet mania and crash of 1990s and the easy liquidity boom and bust of 2000s– are two distinct components of a single structural ...

  • Estimating Intertemporal Allocation Parameters using Synthetic Residual Estimation 

    Alan, Sule; Browning, Martin (CFAP, Cambridge Judge Business School, University of Cambridge, 2008-01)
    We present a novel structural estimation procedure for models of intertemporal allocation. This is based on modelling expectation errors directly; we refer to it as Synthetic Residual Estimation (SRE). The flexibility of ...

  • Detecting Contagion with Correlation: Volatility and Timing Matter 

    Dungey, Mardi; Yalama, Abdullah (CFAP, Cambridge Judge Business School, University of Cambridge, 2010-05)
    We examine whether contagion tests are affected by controls for volatility clustering and the collection of synchronized data sets. Without controlling for volatility clustering synchronization does not apparently matter. ...

  • Do Disaster Expectations Explain Household Portfolios? 

    Alan, Sule (CFAP, Cambridge Judge Business School, University of Cambridge, 2010-03)
    It has been argued that rare economic disasters can explain most asset pricing puzzles. If this is the case, perceived risk associated with a disaster in stock markets should be revealed in household portfolios. That is, ...

  • Experimental investigations into high-altitude relight of a gas turbine 

    Read, Robert William (University of CambridgeDepartment of Engineering, 2008-11-18)
    This thesis describes experiments to investigate high-altitude relight of a lean direct injection (LDI) combustor. The features that make LDI technology less polluting in terms of NOx compared to conventional combustors ...

  • From Trade-to-Trade in US Treasuries 

    Dungey, Mardi; Henry, Olan; McKenzie, Michael (CFAP, Cambridge Judge Business School, University of Cambridge, 2010-05)
    The aim of this paper is to model the trading intensity of the US Treasury bond market which has a unique expandable limit order book which distinguishes its structure from other asset markets. An analysis of tick data ...

  • Selective cation-exchange adsorption of the two major whey proteins 

    El-Sayed, Mayyada (University of CambridgeDepartment of Chemical Engineering and Biotechnology, 2010-03-16)
    Whey is a by-product of cheese manufacture, containing a mixture of proteins of commercial value, each having unique attributes for nutritional, biological and food ingredient applications. A tremendous amount of whey, ...

  • Engineering Fundamentals of Energy Efficiency 

    Cullen, Jonathan M. (University of CambridgeDepartment of Engineering, 2010-03-16)
    Using energy more efficiently is essential if carbon emissions are to be reduced. According to the International Energy Agency (IEA), energy efficiency improvements represent the largest and least costly savings in carbon ...

  • Tomographic PIV measurement of coherent dissipation scale structures 

    Worth, Nicholas (University of CambridgeDepartment of Engineering, 2010-05-04)
    Further understanding the small scale coherent structures which occur in high Reynolds number turbulence would be of enormous benefit. Therefore, the aim of the current project was to make well resolved three-dimensional ...

  • Rainfall trends in India and their impact on soil erosion and land management 

    Pal, Indrani (University of CambridgeDepartment of Engineering, 2010-02-09)
    Under the threat of global warming it is vital to determine the impact that future changes in climate may have on the environment and to what extent any adverse effects can be mitigated. In this research an assessment was ...

  • Scalar dissipation rate based flamelet modelling of turbulent premixed flames 

    Kolla, Hemanth (University of CambridgeDepartment of EngineeringTrinity Hall, 2010-03-16)
    Lean premixed combustion has potential for reducing emissions from combustion devices without compromising fuel efficiency, but it is prone to instabilities which presents design difficulties. From emissions point of view ...

  • Feedback control of oscillations in combustion and cavity flows 

    Illingworth, Simon J (University of CambridgeDepartment of Engineering, 2010-02-09)
    This thesis considers the control of combustion oscillations, motivated by the susceptibility of lean premixed combustion to such oscillations, and the long and expensive development and commissioning times that this is ...

  • DOLFIN: Automated Finite Element Computing 

    Logg, Anders; Wells, G N (2009)
