Quantitative Macroeconomic Modeling with Structural Vector Autoregressions – An EViews Implementation

by Sam Ouliaris, Adrian Pagan and Jorge Restrepo

Quantitative macroeconomic research is conducted in a number of ways. An important method has been the use of the technique known as Structural Vector Autoregressions (SVARs), which aims to gather information about dynamic processes in macroeconomic systems. This book sets out the theory underlying the SVAR methodology in a relatively simple way and discusses many of the problems that can arise when using the technique. It also proposes solutions that are relatively easy to implement using EViews. Its orientation is towards applied work and it does this by working with the data sets from some classic SVAR studies. This book is now updated for EViews 10, which has many new features that deal with VARs and SVARs.

In this updated manuscript we first present how to estimate SVARs if one only has EViews 9.5 and then we re-do the same exercises using EViews 10. As we will see it is generally much easier to work with EViews 10.

Sam Ouliaris is a former Deputy Division Chief in the European and Middle East Division of the IMF’s Institute for Capacity Development (ICD). Prior to joining the IMF’s Institute in 2009, he was a staff member of the IMF’s Research Department (2003–2005), and its Western Hemisphere Department (2005–2009). During 2014-2015, Mr. Ouliaris was Chief of the IMF’s Internal Economics Training Unit, which is responsible for organizing training for IMF staff and visiting country officials.

Dr. Ouliaris holds a Ph.D. in Economics from Yale University specializing in econometrics (time-series analysis, macroeconomic forecasting) and macroeconomics. Before 2011, he was a professor at the National University of Singapore, which he joined in 1988. He has served as a consultant to a number of ministries in Asia, including the Monetary Authority of Singapore, and the Bank Negara Malaysia.

Adrian Pagan is an Emeritus Professor of Economics at the University of Sydney and a Professorial Research Fellow at the University of Melbourne. He has held Professorial appointments at the Australian National University, the University of Rochester, the University of New South Wales and Oxford University.

Professor Pagan is the author of around 150 articles and 4 books. He has been elected to Fellowships of the Econometric Society, the Australian Academy of Social Sciences, the Modelling and Simulation Society of Australia, the Journal of Econometrics, and the Journal of Applied Econometrics. He has been an editor of Econometric Theory and the Journal of Applied Econometrics and an associate editor of Econometrica. He has also co-edited Advanced Texts in Econometrics, (Oxford University Press) and Themes in Modern Econometrics (Cambridge University Press).

In addition to his academic work he has been a Member of the Reserve Bank of Australia Board (1995-2000) and has advised a number of central banks on modeling issues, including the Bank of England, the Norges Bank, the European Central Bank and the Reserve Bank of New Zealand.

Jorge Restrepo is a Senior Economist in the Institute for Capacity Development’s Western Hemisphere Division. Prior to joining ICD in 2010, Dr. Restrepo worked 10 years for the Central Bank of Chile’s Economic Research Department, and also worked at the Central Bank of Colombia. Mr. Restrepo received his Ph.D. in Economics from New York University. His research includes papers on inflation targeting, demand for money, equilibrium unemployment, fiscal rules, and central bank balance sheets.
