 Harvard conomist Ricardo Hausmann, Juan Guaidó's representative to the Inter-American Development Bank, asserts that the analysis is flawed because it makes invalid assumptions about Venezuela based on a different country, Colombia, saying that "taking what happened in Colombia since 2017 as a counterfactual for what would have happened in Venezuela if there had been no financial sanctions makes no sense".Calling it "sloppy reasoning", the authors also state that the analysis failed to rule out other explanations, and failed to correctly account for PDVSA finances.Weisbrot was an advisor, and co-wrote with Tariq Ali the screenplay for the Oliver Stone's 2009 film, "South of the Border", which examined the "pink tide" of elected leftist governments in South America.
