US Postal Service – reduced volumes = reduced costs
In February this year, the United States Postal Service (USPS) decided to cease delivering mail on Saturdays. While this may be seen as inconvenient for some personal and business users, in management accounting terms it is probably a simple cost-volume issue.
Mail volumes have fallen globally due to email and other communications media. With falling volumes, a postal service would either have to reduce costs or increase revenues to maintain profits – or keep state subsidies low. Increasing revenues may be difficult given the competition is sectors such as parcel deliveries, which have increased in volumes. It is also difficult to raise postage rates given the political and/or state involvement. So this leave costs, or more specifically cost-cuts, to get things back in balance. Apparently, ceasing Saturday deliveries will save $2 billion annually. You can read more here from The Economist
