Erwin Rothbarth was a German economist and statistician. He worked as a research assistant for John Maynard Keynes and made important contributions to the measurement of GDP and the modelling of individual consumption. Rothbarth was born in Frankfurt am Main to a German Jewish family, his father, Otto Rothbarth was a lawyer. Rothbarth joined the Social Democratic Party of Germany, he studied Law at the University of Frankfurt from 1932 to 1933, when he fled Germany to the United Kingdom. He graduated from the London School of Economics in 1936 and remained there as a researcher in economics and statistics until 1938, he moved to Cambridge University in 1938 and became a research assistant for John Maynard Keynes in 1939. From May to August 1940 Rothbarth was interned by the British government due to his German nationality. In September 1940 he married Myfawwy Charles, he volunteered for the Suffolk Regiment of the British Army and was killed in heavy fighting near Venray, The Netherlands. While working as Keynes' research assistant for the influential article How to Pay for the War Rothbarth developed techniques which are now used to calculate GDP.
Rothbarth calculated for Keynes statistics for private income and outlay, government income and outlay, national output, savings and investment. Rothbarth's main contribution, the main advancement from the older work of Colin Clark on national income, is the concept of Gross National Income, a large component of modern GDP figures. Rothbarth's and Keynes' figures are the first GDP figures to be based on a double-entry accounting system in order to ensure their accuracy; the problem of New Goods in Industrial Organisation is of how to estimate the value that consumers put on the availability of goods and services which did not exist. A book-length treatment of the subject by Timothy Bresnahan and Robert J. Gordon credits Rothbarth with pioneering the subject in his 1941 article'The Measurement of Changes in Real Income under Conditions of Rationing'. Rothbarth's treatment of the problem was the first mathematical attempt at the problem, his approach involves the estimation of a'virtual reservation price' at which consumers would choose to purchase none of the good and examining the changes in consumers' consumption choices once the new good becomes available in order to infer the consumers' valuation of the new good.

Together with the Dragoons and Uhlans, the Imperial and Royal Hussars, made up the cavalry of the Austro-Hungarian Army from 1867 to 1918, both in the Common Army and in the Hungarian Landwehr, where they were known as the Royal Hungarian Hussars. The Austrian monarchy, weakened by the losing the war against Prussia in 1866, had to guarantee the autonomy of Kingdom of Hungary in the so-called Compromise of 15 March 1867; as a result, the Hungarian half of the Empire began to establish its own army, the Royal Hungarian Landwehr. The cavalry of the Hungarian Landwehr was made up of the Landwehr Hussars. Following the signing of the Compromise, the Austrian half of the Empire started to build an army, the Imperial-Royal Landwehr; the two new Landwehr forces thus existed alongside the Common Army, the imperial army of the whole Empire. In effect this meant; the Common Army had 16 hussar regiments and the Royal Hungarian Landwehr had ten. By tradition, the majority of the hussars were recruited from the Hungarian lands.
The regiments, with a few exceptions, were all stationed there. The Imperial and Royal Cavalry regiments each had two divisions each of three squadrons A list of the Imperial and Royal Hussars regiments in 1914 is given below by short title. 1st Hussars 2nd Hussars 3rd Hussars 4th Hussars 5th Hussars 6th Hussars 7th Hussars 8th Hussars 9th Hussars 10th Hussars 11th Hussars 12th Hussars 13th Hussars 14th Hussars 15th Hussars 16th Hussars The regiments listed below were part of the Royal Hungarian Hussars known as the Royal Hungarian Honved Hussars, Honvéd being Hungarian for "Home-defender".
