The Central Bank of Iceland's Quarterly Macroeconomic Model (QMM) has been updated
Several model equations have been re-estimated and the national account components are now forecasted by using the chain-volume approach, using the year 2000 as a base year. In addition, external trade has now been separated into goods and services trade. For further information about the new updates to the model, see p. 13 in the QMM handbook.
