Electronics Industry In the U.S. alone, 40 million PCs become
obsolete every year According to the UN, 50 million tones of
e-waste is discarded globally every year Only 20% of this is
recycled, the rest ends up in landfills Of the 20% recycled, 80% is
shipped to developing countries

- Hardin, Science (1968) - http://dieoff.org/page95.htm
http://dieoff.org/page95.htm Herdsmen grazing cattle on common
pasture Entire benefit of adding one animal goes to owner
Disbenefit of overgrazing (plant destruction, soil erosion) caused
by adding one more animal is shared by all Each herdsman adds one
more, then one more, . Conclusion: Freedom in a commons brings ruin
to all. Tragedy of the Commons
- Slide 13
- The commons as the food basket Water, fisheries, timber, etc
The commons as the cesspool Sewage, waste, CO 2 emissions, etc. "So
that's where it all goes! Well, I'd like to thank you fellows for
bringing this to my attention."

- Remanufacturing in the US Remanufacturing is a $53 B industry
in the US. e.g. motor vehicle parts, office furniture, engines,
tires, copiers, cell phones, heavy equipment, PCs, toner
cartridges, single- use cameras 73,000 firms, 480000 direct
employment. Both OEMs and third-party firms remanufacture.

responsible for it cradle to cradle is the future. (1996)

(1996) product reuse extends the useful life of equipment,
especially at the end of leasing agreements when consumers return
products... Xeroxs Green Line: refurbished off-lease products
Promoted by U. S. EPA, NYC Government and State of Minnesota.
Reduce Reuse Recycle
- Slide 57
- Motivation Arguments against Leasing Premature disposal due to
cannibalization concerns. What about environmental impact due to
the production and use phases? Is leasing more profitable than
selling? What is the profit-maximizing strategy and when can it
also be environmentally superior?
- Slide 58
- Related Literature and Contribution Durable Goods: Focuses only
on profitability of leasing and selling. Coase (1972), Stokey
(1981), Waldman (1997), Desai & Purohit (1998,1999), Huang et.
al (2001), Bhaskaran and Gilbert (2005,2009). Closed-Loop Supply

Ecology: Only focuses on the environmental performance of a single

- Slide 59
- The Model We compare a pure leasing strategy with a pure
selling strategy. Product has a useful life time of two periods.
Discrete-time, Infinite Horizon, Dynamic game. Under leasing,
operating lease of one period duration. Under selling, there is an
independent secondary market. Cost of producing a new product is c.
Remarketing and Transaction costs are normalized to zero.

higher aggregate consumer surplus? If a strategy has higher profit
and lower environmental impact, it also has higher consumer
surplus. Win-Win-Win! LS Effective cost under Leasing Effective
cost under Selling Selling Leasing
- Slide 82
- Conclusions The remarketing level is not a good proxy for the
environmental performance of leasing. Disposal cost is an important
driver of the firms choice. Leasing can be a win-win strategy for
products with high use impact and selling for products with high
production and disposal impact.
