Country Total Support Estimate (TSE) and derived indicators in
Table 1 cover all agricultural production, i.e. all
agricultural commodities produced in the country. Definitions of basic data sets
refer to the specific name of the programmes. For the
Producer Support Estimates (PSE) and Consumer Support Estimates (CSE),
the description of policy measures indicates the commodities covered by the
measures, as well as the method of allocation of the corresponding transfers
among commodities. MPS commodities, which vary across countries, are those for
which market price support is explicitly calculated in Table 2.

Market Price Support (MPS) and Consumer Support Estimates (CSE) by
commodity in Table 2 are calculated for the following commodities:
wheat, maize, barley, oats, milk, beef and veal, pigmeat, poultry meat, sheep meat, wool, and eggs.
Definitions are provided only for basic data sets from which all the other data
sets in this table are derived, following the formula indicated in each
commodity table. Specific sources are indicated in square brackets.

Producer Support Estimates (PSE) by commodity in Table 3 are
calculated only for the commodities produced in the country within a common set
of commodities (wheat, maize, barley, oats, rice, soybeans, sunflower, rapeseed, sugar,
milk, beef and veal, pigmeat, poultry meat, sheep
meat, wool, and eggs), provided that the value of production of that commodity
exceeds 1 per cent of the total value of production in the country concerned.
All data sets in the calculation of PSE by commodity come from
Tables 1 and 2 where definitions are included.

Definitions
of the indicators, criteria of classification of programmes included, and methods of calculation can be seen
in OECD, Methodology for the measurement of support and use in policy
evaluation [http://www.oecd.org/agr/policy].

Conversion factors:

Milk tonnes = thousand litres / 1.031

Eggs tonnes = million
dozen x 12 (eggs) x 58.5 (grams per
egg)

Sheep tonnes = number
exported live x 0.020

Wool cons. tonnes = clean
wool consumed x 1.33

Crop years:1 April 1986-31 March 1987 crop year is
referred as "1986" and covers data denoted in the reference source as "1986/87".
Note that, in contrast, when the
New Zealand
authorities use statistical year "1979", they are referring to
"1978/79".

Marketing years: Vary according to livestockproducts.
The following examples are referred to as "1986":

Cereals, poultry and eggs, milk, meats and
wool: Implicit average farm-gate price calculated by dividing the
value of production by the level of production. Since 1987, barley price
refers only to feed barley.

Beef and veal: Local disappearance of beef
and veal, including farm and rural slaughterhouse kill, carcass weight; and
carcass weight equivalent of canned and miscellaneous processed beef and
veal [3].

Milk: Implicit price obtained by subtracting
the unit value of the "Town milk premium" (value of the domestic effect of the
government’s administered pricing policy for liquid milk divided by total
production) from the producer price for 1986 and 1987. Since then
there is no market price support measures [5].

Pigmeat: Implicit import
price obtained by applying the tariff rate to the wholesale price
(estimated as the producer price plus processing margin estimated at
50 per cent of the producer price).

Poultrymeat: Implicit US
export price obtained by subtracting the average unit value of the export
subsidy (total value of the US Export Enhancement Programme (EEP) divided by total exports) from
the US
producer prices [6].

Eggs: Export unit value of
eggs-in-shells exported by the European Community minus processing margin
estimated as 5 per cent of the producer price
[7].
