GDP: 
"GDP data from 1865 to 1938 are from Norway, Statistisk"
"Sentralbyra (1965, T. 49, r. 11, pp. 340-343), current prices,"
millions of kroner.  

Capital formation: 
"Capital formation data from 1865 to 1938 are from Norway,"
"Statistisk Sentralbyra (1965, T. 49, r. 5, pp. 340-343),"
"current prices, millions of kroner. Data include increase in"
stocks from 1909.  Data on increase in stocks for 1900-1908
"are from Statistisk Sentralbyra (1953,  T. 2, p. 107, col. 9),"
Lagerendring (change in stocks). Data for 1909-1939 are from
"Statistisk Sentralbyra (1965, T. 49, pp. 340-343, r. 7)."
Increase in stocks not estimated for the years 1865-1899. For
1900-1913 and 1921-1929 only net increase in standing forests
and in livestock are included. From 1930 increase in standing
forests is regarded as fixed capital investment.  

Current Account: 
Current account data from 1865 to 1899 are from Mitchell
"(1993, T. J3, pp. 922, 927), current prices, millions of"
kroner. Current account data for 1900-1929 are from Statistisk
"Sentralbyra (1953,  T. 12, p. 126, col. 5), Netto oking eller"
nedgang i Norges netto fordringer pa utlandet (Net increase or
decrease in Norway's foreign assets). Data for 1930-1939 from
"Statistisk Sentralbyra (1965, T. 25, pp. 184-185, r. 16). The"
current account data exclude crude gold and silver and coins.  

Gold:  
Data on gold and silver holdings from 1865-1913 are (the two
"metals are not reported separtely) from Norway, Statistisk"
"Sentralbyra (1978, T. 257, col. 1&6, p. 484), Metallfondene (gold and silver) at bank of Norway. Data from 1914-1939 from"
"Statistiske Oversikter (1948, T. 159, rows. 1 & 4, pp."	
"300-303), Gullbeholdning (gold stock), and Midlertidig anbrakt"	
i gull (temporarily invested in gold). The change in the	
monetary gold stock is calculated as the first difference of	
the gold stock at the Bank of Norway (gold and silver stock	
"until 1914).  According to United States, Report of the"	
"Director of the Mint (1886, p. 222), “the amount of gold in"	
"banks, other than the Bank of Norway, or in circulation, has"	
probably not been considerable.”	
	Data on gold exports and imports for 1865 to 1896 are
calculated as the first difference of the gold and silver 	
holdings of the Bank of Norway (the negative of the change in	
"the  monetary stock equals the net exports -- i.e., an"	
increase in the monetary stock corresponds to an import). 	
Data on gold exports and imports from 1895 to 1909 and for	
"1931 to 1944 are from Norway, Norges Handel (annual issues),"	
"unwrought platinum, gold and silver and coins and medals. "
Missing trade returns data for 1897 and 1899 are interpolated 
linearly from the previous and subsequent years.   Data on net
exports of gold from 1910 to 1930 are from the League of
"Nations (1927, 1931, 1932), exports of bullion and specie less"
"imports of bullion and specie (including silver and platinum,"
as per the trade returns).
