Measuring the Multiplier
One group of researchers use a regression analysis technique known as SVAR[1] to determine the typical reaction of output to previously recorded fiscal changes. The problem about this method is that fiscal changes have often been taken in response to other things happening in the economy. Separating the impact of those other factors from the impact of fiscal change can be very difficult, and failure to do so successfully can result in omitted-variable bias resulting in an underestimate of the multiplier. According to Christine Romer, that has been a common cause of error[2]. Another approach involves the use of a previously calibrated general equilibrium (DSGE[3]) model of the economy
