The share of total consumption and fixed investment in GDP in Asia and the Pacific has been mostly unchanged since the crisis began, or even lower in open economies, such as Azerbaijan, Brunei Darussalam, Turkmenistan and Taiwan Province of China. Implementation of policies to support domestic demand can be accelerated, including through enhancing the agricultural and services sectors, strengthening small businesses, providing stronger social safety nets to reduce precautionary savings, and upgrading public infrastructure. Some analysts argue that the booming years of 2006-2007 were largely fuelled by imbalanced growth in developed economies, thus generally viewed as exceptional and unsustainable.
