SBRANA Giacomo
Post-Doctorate in Econometrics
Giacomo SBRANA is Full professor at NEOMA Business School since 2019. He joined the school as assistant professor in August 2011 and became Associate professor in 2014. Before joining NEOMA, from 2005 until 2009, he worked as associate expert at the Department of Economic and Social Affairs of the United Nations in New York (USA).
Giacomo holds a M.Sc. in Economics and Econometrics from the University of Southampton (obtained in 2003), a PhD in Statistics from the University of Roma TRE (obtained in 2004) and a postdoc at BETA, Université de Strasbourg (from 2009 until 2011).
His teaching activities mainly focus on statistics and quantitative methods also coding with Python and R at both undergraduate (MiM programme) and postgraduate level (MSc and PhD).
His primary research interests include time series analysis and forecasting especially using State-Space models and the Kalman filter. He has published in several academic journals such as: International Journal of Production Economics, Journal of Banking & Finance, International Journal of Forecasting, Macroeconomic Dynamics, Cliometrica, Journal of the Operational Research Society, Economic Modelling, Journal of Time Series Analysis, Journal of Forecasting, Journal of Multivariate Analysis, Bulletin of Economic Research
