Data on trade policies on the global agri-food markets first appear in the global database of CAPRI. More specifically, the original tariff data are aggregated to the commodity definitions of CAPRI in the tariff aggregation module. The tariff aggregation procedures in CAPRI require data not only on the tariffs themselves but also on traded quantities and import prices. two tariff/trade databases are supported currently:

1. AMAD database, which is unfortunately discontinued by OECD and is expected to be phased out from the CAPRI system as database updates will be no longer available.
2. ITC-MacMap and ITC-TradeMap database. MacMap includes ad valorem equivalent tariff rates at the 6-digit level of the Harmonized System (HS6), while TradeMap supplies the necessary trade statistics (quantities and prices) for the aggregation.

The tariff aggregation results are part of the .gdx output of the global module, and can be found in results\global\tariffs.gdx.

Although the tariffs in the tariff databases should already reflect the tariff schedules of the implemented Free Trade Agreements (FTA) on global agricultural markets, CAPRI nevertheless explicitly includes data on a number of FTAs. That FTA-specific policy information enters the CAPRI system in the market model calibration workstep (gams\arm\def_tariff.gms, see Table below for the list of implemented FTAs).

Specific trade policy data on Switzerland enters CAPRI both in the tariff aggregation module (in the global) part and also during market model calibration, and often overwrites tariff data from the above sources. The Switzerland-specific datasets in CAPRI are managed by the team at the Federal Office for Agriculture, and the data are based on national trade statistics: Swiss-Impex database and the databases of the TRIMAG tariff aggregation tool¹⁾. The relevant model code is collected under the subfolder gams\special_ch.

Data on trade policy instruments other than tariffs (Tariff Rate Quotas, export subsidies, entry price system and flexible levies) enter CAPRI directly in the market model calibration workstep. Note that the ad valorem equivalent tariff rates in MacMap already include an estimated equivalent tariff rate for TRQs. Nevertheless, the CAPRI market model separates TRQs from fixed tariff rates by using a sigmoid function-representation of the TRQ regime switch mechanism²⁾.

The TRQ system of the EU is included in great detail, based on DG AGRI.information. Data on TRQ orders are aggregated to the geographical and commodity definitions of CAPRI in dat\arm\TRQ_orderds.gms. Specific GAMS routines convert some of the compound TRQs into ad valorem TRQs if necessary³⁾(gams\arm\convert_compound_trqs.gms).

Data on (EU) export subsidies (e.g. maximum commitments) enter the system in the market model calibration workstep, under gams\arm\calc_feoga.gms. Current WTO negotiations aim at the full phase-out of export subsidies, and accordingly, the EU does not grant export subsidies to agricultural products currently. Nevertheless, the possibility to introduce export subsidies in policy scenarios is kept in CAPRI (e.g. Border Carbon Adjustment policies may take the form of export subsidies, for which the availability of the export subsidy mechanism is valuable).

Producer Subsidy Estimates (PSE) are formally part of the price transmission equations in the market model from the (equilibrium) market prices to the producer prices. However, a complete and up-to-date PSE dataset is not part of CAPRI at the moment, and therefore PSE support is not considered in the standard version of CAPRI (was only available in some specific model applications only).

Consumer Subsidy Estimates (CSE) are formally part of the price transmission equations in the market model from the (equilibrium) market prices to the consumer prices. However, a complete and up-to-date CSE dataset is not part of CAPRI at the moment, and therefore CSE support is not considered in the standard version of CAPRI (was only available in some specific model applications only).

Data on public intervention (stocks, buy-ins, releases, administrative prices etc.) enter the system in the market model calibration workstep, under gams\arm\calc_feoga.gms. Once one of the most impactful measure of the Common Agricultural Policy (CAP), public intervention has been reduced regarding its scope and is currently only available for EU farmers as an emergency measure (in crisis situations, e.g. under exceptionally high price fluctuations). Therefore, its use in CAPRI is also limited to scenario analysis.
