While there are reasons why a larger government spending multiplier is worse than a smaller one, I would say that a multiplier of 8 is better than a multiplier of 2.
In general, it is somewhat bad to have a multiplier that is too big. This is because such a multiplier makes it harder to keep the economy stable. If the multiplier is very large, every change in government spending has a very large impact on the economy. If government spending goes up a relatively small amount, it could lead to a very large increase in GDP, potentially causing the economy to overheat. If government spending declines, it could lead to a large decrease in GDP, potentially triggering a recession. Therefore, we could argue that it is better to have a smaller multiplier.
However, I would argue that a multiplier of 2 is too small. This is because a multiplier of 2 indicates that the marginal propensity to consume (MPC) in the economy is very low. The multiplier is determined by the formula
Multiplier = 1/(1 – MPC)
Given this formula, we can determine that the multiplier is 2 if the MPC is .5. This would mean that people would be spending only $.50 of each additional dollar of income that they receive. If there was this little consumption, the economy would probably not be doing very well.
Therefore, while a very high multiplier is bad, a multiplier of 2 would tend to indicate that consumer spending is rather low, which could well be a symptom of a very weak economy.
