Keeping Track of the Maintenance Dollar

THE selling price of commodities or services is more often than not determined by adding a reasonable profit to the total cost of manufacture and distribution.

Three International Meetings

WHILE the three meetings of which the proceedings are listed here have enough similarity to justify a common treatment, they differ widely in purpose and background. The meeting at Tokyo, like earlier world power conferences in Europe, was literally a world-wide affair, with almost 300 organizations participating and about 700 foreign members and 3,000 Japanese attending.

Notes on Governmental Economy

THE halcyon days are over. Years when every Treasury estimate of governmental finance, however roseate, proved to have been conservative have given way to years in which the federal deficit gathers momentum like a snowball and finally has to be measured in ten figures.
