“It is my hope that in such a way we may again, as Marx claimed, find scientific arguments in the competition between various systems, but up-to-date scientific arguments rather than obsolete ones. This more fundamental research in economics deserves relatively more attention and resources than the more superficial versions of economic research directed at forecasting or analysing very short-term fluctuations in market prices, on which quite some money is being spent to-day.”

“The shaping or reformulation of the aims of economic policy which are only vaguely felt may be exemplified in the aim of social justice.”

“The central question of economic policy is the question of the effectiveness of its various instruments.”
