A demand side approach to forecasting is fundamentally different from the econometric modeling that dominates the forecasting world. We begin with the presumption, which we think has been theoretically and empirically validated over the past century, that the economy responds to aggregate demand. We then assess the likely influences on demand going forward and apply estimates of the multipliers to each influence.
Our explanation uses mathematics, but is not an equation or formula, because the assumptions that underly the models are the core of the understanding, not the mechanical devices used to manipulate the assumptions.
