Nicholas Kaldor (Budapest, May 12th 1908 - Papworth Everard, Cambridgeshire, September 30th 1988) is known to have been one of the principal economists keynésiens of the school of Cambridge. It developed the concept of Optimum of Kaldor-Hicks for the comparison of the industrial relations policies.

Although it took an active part in various research, its principal contribution with the economy keynésienne relates to the dynamic effects of the speculation which it studied with an aim of creating a theory of the business cycles endogenous. What led it besides to run up against the positions of Friedrich Hayek.

It is also known to have integrated concepts ricardiens in its theory of the growth, which will be then largely re-used in the born theories Post-keynésien and néo-ricardiennes.

Most of the work of Nicholas Kaldor is centered on criticism of the theories neo-classic monetarists and and of the policies which of it result.

It was named even with life in 1974 with the title of Baron Kaldor off Newnham in the City off Cambridge .
