| Summary: | This paper provides an overview, macro
application, and detailed documentation of GEM-Core, a
dynamic computable general equilibrium (CGE) model designed
for medium- and long-run policy analysis. GEM stands for
General Equilibrium Model. GEM-Core can address the issues
that typically are relevant for CGE analysis for developing
countries, including fiscal space (with its spending, tax,
and foreign aid aspects), public investment, social safety
nets, trade, jobs, demography, poverty, and inequality. The
model is a template model in the sense that, given an
appropriately formatted database, applications for different
countries can quickly be developed. The data needed for
macro applications are very limited, making it possible to
apply the model on short notice to virtually any country,
including fragile and low-income countries. GEM-Core comes
with a user-friendly Excel-based interface through which the
analyst may choose between alternative country databases
and, for the selected database, do the analysis (define and
analyze simulations, including adjustment of selected data
and assumptions). The interface lowers entry barriers to CGE
modeling and provides a platform around which training may
be organized, making it possible to focus courses on
economics instead of computer programming. |
