Norway’s economy has continued to prosper with continued growth in average incomes, low inequality, low unemployment and low inflation. Petroleum wealth has contributed to high incomes and supported the non-petroleum (mainland) economy; around 8% of mainland production is estimated to be directed towards supplying the offshore sector. At the same time, the prudent policy of saving almost all of net profits from petroleum as public sector assets has mitigated the impact of terms of trade fluctuations while building up a substantial stock of financial assets held in the Government Pension Fund Global. The value of this fund was about 200% of mainland GDP, some USD 800 billion, by the end of 2013.
