IIPA Methodology
Video: The term encompasses movies provided in video cassette as well as in optical disc formats. Losses are estimated using one of the following methods:
-
For developed markets:
-
The number of stores that rent pirate videos and the number of shops and vendors that sell videos are multiplied by the average number of pirate videos rented or sold per shop or vendor each year.
-
The resulting total number of pirate videos sold and rented each year in the country is then multiplied by the percent of those pirate videos that would have been sold or rented legitimately and adjusted to reflect the US producer’s share of the market.
Total pirate videos sold/rented = # of stores/shops that sell and rent pirate videos * ave. # of pirate videos rented/sold per shop each year
Loss due to piracy = Total pirate videos sold and rented per year * (% videos that would have been sold or rented legitimately)
-
For partially developed markets:
-
The number of legitimate videos sold or rented in the country each year is subtracted from the estimated total number of videos sold or rented in the country annually to estimate the number of pirate videos sold or rented annually in the country.
-
The resulting total number of pirate videos sold and rented each year in the country is then multiplied by the percent of those pirate videos that would have been sold or rented legitimately and adjusted to reflect the US producer’s share of the market.
Total pirate videos sold/rented = estimated total # of videos sold/rented # of legitimate videos sold/rented
Loss due to piracy = Total pirate videos rented/sold * (% pirate videos that would have been sold/rented legitimately
-
For fully pirate markets:
The estimated number of pirate videos of U.S. motion pictures sold or rented in the country each year is adjusted to reflect the wholesale price of legitimate videos which equals losses due to video piracy.
IPC VIDEO PIRACY ESTIMATION METHODOLOGY
National Statistics Office data (1994) on the Proportion of HH by Ownership of Radio, TV, VCR, and PC
-
Determine the growth in sales of VHS, VCD player, and DVD players and PCs
-
Determine the frequency of movie patronage of Filipinos (either per day/month/year)
-
Determine the number of units of videos and VCDs sold/rented per year
-
Determine the Total Revenue from video sales
Formula:
General Concept:
Demand = Supply
Demand Supply = Undersupply
Excess demand will be supplied by the underground economy (pirated videos)
Where:
Base yeart – % of # of HH owning VCRs and PCs at year t
VCR (and other appliances used for video viewing) and PC Ownershipx = Number of HH with VCRs and PCs at year x = (t+1)
DEMANDV,x – demand for film videos (V) at year x = (t+1)
SUPPLYV,x – units of videos/VCDs sold at year t+1
Formula:
VCR = (Base yeart * Total # of HHt) + Total number of appliances for video viewing sold
PC Ownershipx = Number of Installed PCs
VCR and PC Ownership1995 = (% of HH owning VCRs and PCs at year 1994) + number of VCRs sold (in units)1995 + Number of Installed PCs
DEMANDV,x = VCR and PC Ownershipx * frequency of movie patronage at year t+1
Total Pirated Movies = DEMANDV,x SUPPLYV,x
Piracy Rate = (Total Pirate Movies/ DEMANDV,x) * 100
MUSIC/RECORDING PIRACY
IIPA METHODOLOGY
The RIIA generally bases its estimates on local surveys of the market conditions in each country. The numbers produced by the music industry generally reflect the value of sales of pirate product rather than industry losses, and therefore undervalue the real harm to the interests of record companies, music publishers, performers, musicians, songwriters, and composers.
Where RIIA has sufficient information relating to known manufacture of pirate recordings that emanate from a third country, this loss data will be included in the loss number fro the country of manufacture rather than the country of sale.
In certain instances appropriate, RIAA employs economic data to project the likely import or sale of legitimate sound recordings, rather than merely reporting pirate sales. In these instances, projected unit displacement is multiplied by the wholesale price of legitimate articles in that market rather than the retail price of the pirate goods.
IPC METHODOLOGY
General Concept:
Demand = Supply
Demand Supply = Undersupply
Given : TR = RL + RP
Where: RL - Revenue of Legitimate activity; RP – revenue of piracy
RP = TR - RL
(RP / TR) * 100 = piracy rate
