"The government may be regarded as a decision-making entity. Among the decisions it makes are the formation of economic policy and the collection of economic-statistical information. In all modern nations the economic policies of the government are significant activities, if for no other reason than the high proportion of national income which passes through the Treasury; but of course in many countries much more ambitious economic planning is aimed at, though not necessarily achieved. Economic statistics, on the other hand, if one is to judge by expenditures, form only an insignificant proportion of a government's activities and are the least developed precisely in those underdeveloped countries which have the greatest felt needs for economic plans."
