• Macro Modelling with Many Models 

      Bache, Ida Wolden; Mitchell, James; Ravazzolo, Francesco; Vahey, Shaun P. (Working Papers;15/2009, Working paper, 2009)
      We argue that the next generation of macro modellers at Inflation Targeting central banks should adapt a methodology from the weather forecasting literature known as `ensemble modelling'. In this approach, uncertainty about ...
    • Macroeconomic Factors Strike Back: A Bayesian Change-Point Model of Time-Varying Risk Exposures and Premia in the U.S. Cross-Section 

      Bianchi, Daniele; Guidolin, Massimo; Ravazzolo, Francesco (Working Papers;19/2013, Working paper, 2013)
      This paper proposes a Bayesian estimation framework for a typical multi-factor model with time-varying risk exposures to macroeconomic risk factors and corresponding premia to price U.S. stocks and bonds. The model assumes ...
    • Measuring Sovereign Contagion in Europe 

      Caporin, Massimiliano; Pelizzon, Loriana; Ravazzolo, Francesco; Rigobon, Roberto (Working Papers;5/2012, Working paper, 2012)
      This paper analyzes the sovereign risk contagion using CDS spreads for the major euro area countries. Using several econometric approaches (non linear regression, quantile regression and Bayesian quantile with heteroskedasticity) ...
    • Myths and Facts About the Alleged Over-Pricing of U.S. Real Estate. Evidence from Multi-Factor Asset Pricing Models of REIT Returns 

      Guidolin, Massimo; Ravazzolo, Francesco; Tortora, Andrea Donato (Working Papers;19/2011, Working paper, 2011)
      This paper uses a multi-factor pricing model with time-varying risk exposures and premia to examine whether the 2003-2006 period has been characterized, as often claimed by a number of commentators and policymakers, by a ...
    • Oil and Us GDP: A Real-Time Out-Of-Sample Examination 

      Ravazzolo, Francesco; Rothman, Philip (Working Papers;18/2010, Working paper, 2010)
      We study the real-time Granger-causal relationship between crude oil prices and US GDP growth through a simulated out-of-sample (OOS) forecasting exercise; we also provide strong evidence of in-sample predictability from ...
    • Oil Price Density Forecasts: Exploring the Linkages with Stock Markets 

      Lombardi, Marco J.; Ravazzolo, Francesco (Working Papers;24/2012, Working paper, 2012)
      In the recent years several commentators hinted at an increase of the correlation between equity and commodity prices, and blamed investment in commodity-related products for this. First, this paper investigates such claims ...
    • On the Importance of Foreign Factors for the Norwegian Economy 

      Aastveit, Knut Are; Furlanetto, Francesco; Ravazzolo, Francesco (Economic Commentaries;3/2013, Others, 2013)
      The objective of this note is to describe two recent studies that both quantify the importance of foreign factors for the Norwegian economy by using time series econometric models. Furlanetto, Ravazzolo and Sarferaz (2013) ...
    • Optimal Portfolio Choice Under Decision-Based Model Combinations 

      Pettenuzzo, Davide; Ravazzolo, Francesco (Working Papers;15/2014, Working paper, 2014)
      We propose a novel Bayesian model combination approach where the combination weights depend on the past forecasting performance of the individual models entering the combination through a utility-based objective function. ...
    • Parallel Sequential Monte Carlo for Efficient Density Combination: The DeCo MATLAB Toolbox 

      Casarin, Roberto; Grassi, Stefano; Ravazzolo, Francesco; van Dijk, Herman K. (Working Papers;11/2014, Working paper, 2014)
      This paper presents the MATLAB package DeCo (density combination) which is based on the paper by Billio, Casarin, Ravazzolo, and van Dijk (2013) where a constructive Bayesian approach is presented for combining predictive ...
    • Real-Time Inflation Forecasting in a Changing World 

      Groen, Jan J. J.; Paap, Richard; Ravazzolo, Francesco (Working Papers;16/2009, Working paper, 2009)
      This paper revisits inflation forecasting using reduced form Phillips curve forecasts, i.e., inflation forecasts using activity and expectations variables. We propose a Phillips curve-type model that results from averaging ...
    • Term Structure Forecasting Using Macro Factors and Forecast Combination 

      de Pooter, Michiel; Ravazzolo, Francesco; van Dijk, Dick (Working Papers;1/2010, Working paper, 2010)
      We examine the importance of incorporating macroeconomic information and, in particular, accounting for model uncertainty when forecasting the term structure of U.S.interest rates. We start off by analyzing and comparing ...
    • The Macroeconomic Forecasting Performance of Autoregressive Models with Alternative Specifications of Time-Varying Volatility 

      Clark, Todd E.; Ravazzolo, Francesco (Working Papers;9/2012, Working paper, 2012)
      This paper compares alternative models of time-varying macroeconomic volatility on the basis of the accuracy of point and density forecasts of macroeconomic variables. In this analysis, we consider both Bayesian autoregressive ...
    • The Power of Weather. Some Empirical Evidence on Predicting Day-Ahead Power Prices Through Weather Forecasts 

      Huurman, Christian; Ravazzolo, Francesco; Zhou, Chen (Working Papers;8/2008, Working paper, 2008)
      This paper examines the predictive power of weather for electricity prices in day-ahead markets in real time. We find that next-day weather forecasts improve the forecast accuracy of day-ahead electricity prices substantially, ...
    • Why Do People Give Less Weight to Advice the Further It Is from Their Initial Opinion? 

      Ravazzolo, Francesco; Røisland, Øistein (Working Papers;4/2010, Working paper, 2010)
      Experimental studies on decision making based on advice received from others find that the weight put on the advice is negatively related to the distance between the advice and the decisionmaker's initial opinion. In this ...
