"R-2-3, A Simple Global CGE Model to Analyze Macroeconomic Links" by McDonald, Scott Abstract The R-2-3 model (r region country, two sector, and three goods) is a simple and static global computable general equilibrium (CGE) model. It is a generalization of a user-friendly fiscal tool developed at the World Bank for single country analysis - the 1-2-3 model (1 country, with 2 producing sectors, and 3 goods). In the R-2-3 model, many single country 1-2-3 models are linked via trade flows and other macroeconomic variables such as foreign aid, remittances, and other transfers. The R-2-3 model can be used as a as one region model with one trading partner, a one region model with multiple trading partners or as an r region model with multiple trading partners. The database that underpins the model is a global, macro Social Accounting Matrix (SAM), which consists of a series of intra-regional transactions similar to the standard 1-2-3 model but with additional tax/subsidy instruments – import duties, export taxes, other commodity taxes, production taxes, factor use taxes, direct taxes – and total imports and exports by source and destination regions valued fob, trade margins (differences between fob and cif valuations), other current account transactions, e.g., migrant remittances, aid transfers, etc. This database combines and augments in a unique way the GTAP database used in global models and the national and fiscal accounts used in the 1-2-3 model. The GTAP database targets a limited number of macro totals during its construction, namely GDP and the trade data. Other macro totals are collected and used in the reconciliation process (C, I, G), however because these data may be inconsistent with the trade data, they cannot also be targeted. Moreover, certain tax instruments and current account transactions such as remittances and aid flows are missing. This is likely to mean that certain important macro totals may not be consistent with the expectations of country specialists or policy makers. Unfortunately, the detailed SAMs (or IO tables... |
