Hayek continued his research on monetary and capital theory, revising his theories of the relations between credit cycles and capital structure in Profits, Interest and Investment (1939) and The Pure Theory of Capital (1941), but his reputation as an economic theorist had by then fallen so much that those works were largely ignored, except for scathing critiques by Nicholas Kaldor. Lionel Robbins himself, who had embraced the Austrian theory of the business cycle in The Great Depression (1934), later regretted having written the book and accepted many of the Keynesian counter-arguments.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What was the result of Hayek's Prices and Production?
Ah, so.. works were largely ignored

At Buya in Eritrea, one of the oldest hominids representing a possible link between Homo erectus and an archaic Homo sapiens was found by Italian scientists. Dated to over 1 million years old, it is the oldest skeletal find of its kind and provides a link between hominids and the earliest anatomically modern humans. It is believed that the section of the Danakil Depression in Eritrea was also a major player in terms of human evolution, and may contain other traces of evolution from Homo erectus hominids to anatomically modern humans.

Ah, so.. Buya

The origins of the department store lay in the growth of the conspicuous consumer society at the turn of the 19th century. As the Industrial Revolution accelerated economy expansion, the affluent middle-class grew in size and wealth. This urbanized social group, sharing a culture of consumption and changing fashion, was the catalyst for the retail revolution. As rising prosperity and social mobility increased the number of people, especially women (who found they could shop unaccompanied at department stores without damaging their reputation), with disposable income in the late Georgian period, window shopping was transformed into a leisure activity and entrepreneurs, like the potter Josiah Wedgwood, pioneered the use of marketing techniques to influence the prevailing tastes and preferences of society.

Ah, so..
