The Modelling and Policy Impact Analysis (MPIA) program

In recent years, however, MPIA leaders came to find that there was a need for reference models that were more elaborate and closer to real-life conditions than the ones that had been used so far. Moreover, policymakers face new challenges that call for impact assessments that look both forward in time and beyond national boundaries, to the global economy. And so lead researchers of the MPIA program (Bernard Decaluwe, Andre Lemelin, Helene Maisonnave, Veronique Robichaud) have devoted time and energy to creating a series of new standard CGE models that can respond to these needs.

The growing family of PEP standard CGE models


The first of these models, PEP 1-1, designed for country-level studies, was developed as an operational tool for researchers to easily adapt a relatively standard model to their national economy. Building on this basic model, PEP 1-t was created to include evolution in time. Technically speaking, PEP 1-tPEP 1-1 (which is a static or single-period model): it extends the analysis to multiple periods, linking each one to the past through variables inherited from the previous period. 

Since the beginning of 2011, no less than 3 new PEP standard CGE models have been put online. PEP-w-1 is a single-period WORLD model and PEP-w-t is its recursive dynamic version. These new models are based on the Global Trade Analysis Project (GTAP) world-level data base. The latest innovation of the PEP-MPIA team is PEP-w-t-fin, which is, to our knowledge, the only recursive dynamic world model that includes international financial assets.
