
The value of commercial product returns now
exceeds $100 billion annually in the US (Stock,

question asked!!
 Return rates: 6% to 15% (Dekker and Van der
Laan, 2003)
 Mail order companies and e-tailers: as high as
35%
Time Value of Product Returns
 Loss

 Downgraded

to a lower value product
Refurbished/remanufactured/parts/scrapped
 Losses
due to time delays
Deterioration of value in time
 Forced downgrading due to obsolescence

Time Value of Product Returns
Marginal value of time: How much value is lost per unit time?
Low MVT (e.g. power tools)
High MVT (e.g. PCs,
fashion apparel, cell phones)

for efficiency
 There is a trade-off between speed and
efficiency

Centralizes credit issuance, testing, sorting and grading.
Responsive Reverse Chain
Preliminary testing and sorting is done in a decentralized fashion

Managerial recommendations

Treat returns as perishable assets

 Make time a performance metric
 Make the product’s time-value a key design
variable
