The US DoT was meant to report to Congress by 2020-09 but did not and there
seems to be no online trace of the report - perhaps because it made no one happy?
Reports suggest that most impacts slightly increase net costs over any benefits;
and health effects are personally devastating but noise relative to the normal
volume of incidents, such as heart attacks and strokes, and industrial and
traffic injuries.
Changing time offsets or business and education schedules to align better with
solar times may allow a more positive outcome.
DST does increase the amount people drive to golf courses, sporting events, and
to attend barbeques, which probably have negative health impacts, depending on
activities upon reaching the 19th hole or club house ;^>
One lost opportunity cost estimate is now $2G/year - $1G/change - just from
everyone spending 10 minutes changing clocks.
And I saw one estimate that markets lose $31G because of sleepy traders.
[G rather than B because that could look like digit 8 in some fonts!]
Younger householders don't do this as they don't use clocks, watches, or devices
that don't update themselves - except for cooking devices that still have clocks
and not just timers, and SatNav which have only time offset selections not zone
rules, nor geographic lookup a la tzselect, and just DST/Summer Time offset in
effect or not.
So scale that estimate up another three orders of magnitude and ball park $2T to
cancel DST in 47 states, plus add $1T for other impacts including CA, MX, and
international schedules.

A question: to update for a U.S. DST change, what are best estimates for C, H,
and D in the electronics cost formula
C companies *
H hours of staff time per company *
D dollars per staff hour
(H and D values based on past changes elsewhere are most welcome.)
