The IMF and the World Bank are in Washington this week for their 6 monthly meetings and the IMF are already bullying policy makers around the world with their rhetoric that continues the scaremongering about inflation. The IMF boss has told central bankers to resist pressure to drop interest rates, even though it is clear the world economy (minus the US) is slowing quickly. It is a case of the IMF repeating the errors it has made in the past. There is a plethora of evidence that shows the IMF forecasts are systematically biased – which means they keep making the same mistakes – and those mistakes are traced to the underlying deficiencies of the mainstream macroeconomic framework that they deploy. For example, when estimating the impacts of fiscal austerity they always underestimate the negative output and unemployment effects, because that framework typically claims fiscal policy is ineffective and its impacts will be offset by shifts in private sector behaviour (so-called Ricardian effects). That structure reflects the ‘free market’ ideology of the organisation and the mainstream economic theory. The problem is if the theory fails to explain reality then it is likely that the predictions will be systematically biased and poor. The problem is that the forecasts lead to policy shifts (for example, the austerity imposed on Greece) which damage human well-being when they turn out to be wrong.
