I keep hearing commentators tout the benefits of work at home for productivity by eliminating commutes. Less time commuting will not per se raise productivity (not accounting for the impact of less stress when reaching the office on productivity). It simply adds working hours to the day. More hours producing (i.e., “being productive”) does not increase the amount produced per hour (productivity). It does however increase GDP by working harder rather than working smarter. We need more working smarter.
