Budgets of American Wage Earners,” the present volume
affords a comprehensive review of existing cost of living data
in this country and should prove a valuable guide in under-
standing and evaluating the significance of this important
part of modern economic knowledge.
This volume is the result of an investigation conducted by
Miss M. L. Stecker and assistants, of the Conference Board’s
Research Staff, under the supervision of the Board’s Staff
Economic Council.
In the preparation of its studies the National Industrial
Conference Board avails itself of the experience and judg-
ment of the business executives who compose its membership,
and of recognized authorities in special fields, in addition to
the scientific knowledge and equipment of its Research Staff.
The publications of the Board thus finally represent the
result of scientific investigation and broad business experi-
ence, and the conclusions expressed therein are those of the
Conference Board as a body.
