Two leading makers of lighting products are showcasing LED bulbs that are bright enough to replace energy-guzzling 100-watt light bulbs set to disappear from stores in January.
Their demonstrations at the LightFair trade show in Philadelphia this week mean that brighter LED bulbs will likely go on sale next year, but after a government ban takes effect.
The new bulbs will also be expensive — about $50 each — so the development may not prevent consumers from hoarding traditional bulbs.
When I teach introductory econ, I sometimes have trouble coming up with examples of how future expectations can shift current demand (that is, an expected increase in future prices will increase demand today). I usually use things like expected increases in produce prices due to the weather calamity of the day: drought, flood, freeze, locusts, frogs, death of the first born sons of Egypt...Now I have a more current example.
