Alex Izurieta On The UN Global Policy Model

Alex Izurieta compares and contrasts the UN Global Policy Model with models of other international organizations such as the IMF, the OECD and the EU:

A central proposition in this essay is that global models cannot be taken to represent objective and scientific tools for policy analysis. Clearly, all models have to make simplifications and in doing so they will fail to capture some dimensions of economic reality. … Unfortunately, the dominant models proposed by the mentioned IOs ignore essential features of the socio-economic system and therefore deliver a seriously distorted view of policy impacts. Most salient are their assumptions about economic growth, distribution, fiscal and monetary policy, and their failure to address problems of global aggregation—that is, of adding up variables for each world region to account for all relevant macroeconomic factors.

Also an important point on “structural reforms”,

In a different model, such as the UN GPM, structural reforms that depress wages and increase inequality in one country have negative repercussions in other countries that tend to reduce aggregate demand in the world as a whole
