and weak technology bases, implying low short-term and slow instantaneous
responses to policy efforts. From the operational standpoint, because it is
modular (an implication of the weakness of intersectoral linkages) and recursive,
as opposed to the truly instantaneous, the model can be programmed and solved
on interactive, user-friendly, and versatile spreadsheet systems such as LOTUS-
123 and JAVELIN.
45 There is no need for a true simultaneous equation solver
such as GAMS. Moreover, because recursive systems are also equally adaptive,
the multilevel framework allows for routine sensitivity analyses and periodic
data revisions, valuable model attributes when working with data-scarce
countries. Relatively simple distributed lag functional forms can be used to
specify the behavioral equations in such a model, which contributes to making it
particularly data frugal from the econometric standpoint. Finally, because it is
structured in interrelated modular blocks, the multilevel framework provides
great flexibility in model design, including level of disaggregation, market
closure, phased model implementation, and decentralized model maintenance.
The Revised Minimum Standard Model (RMSM) and its most recent
extensions (RMSM-X and RMSM-XX) are the standard policy planning tools supported
by the World Bank and widely used by country economists at the Bank. See D. Addison, Revised Minimum Standard Model ( Washington, D.C.: World Bank, 1989) for a compact
description of the generic RMSM.
TABLO is an acronym derived from the initials of its authors, namely: Tommasi Daniel, Aerts Jean Joel, Blaise Leenhardt, and Olive Gaston. It represents the
standard short- to medium-term macroeconomic projection device for the French "Caisse
Centrale de Cooperation Economique". See B. Leenhardt, Exposition de TABLO,
Modéle Standard de Projection 'a Court; et Moyen Terme de la CCCE, Version 1.1 ( Paris: CCCE, DEG, 1988), for a detailed description of TABLO. The model has been applied to
a number of Francophone countries in SSA, including Congo, Gabon, Cameroon, Côte
d'Ivoire, Burkina Faso and Burundi.
