How does the change in consumer and producer surplus compare with the tax revenue?
Considering the following supply and demand equations:
Qs=3P-1 Qd=-2P+9 dPdt=0.5(Qd-Qs)
Find the expressions: P(t), Qs(t) and Qd(t). When P(0)=1, is the system stable or unstable?
If the constant for the change of excess of demand changes to 0.6, this is: dPdt=0.6(Qd-Qs) do P(t), Qs(t) and Qd(t) remain the same when P(0)=1?

The debt/GDP is always positive during this period, so the Federal Government of the United States incurred in budget deficits every year since 1939. From the mid-40s until the mid-70s, the debt/DGP was decreasing, meaning that the Federal Government of the United States was running a budget surplus every year during those three decades. During the second half of the 1970s, the Federal Government…arrow_forward
- An imaginary country estimates that their economy can be approximated by the AD/AS model below. How can this government act to move the equilibrium to potential GDP? LRAS Price Level P Y Real GDP E SRAS AD The AD/AS model shows that a contractionary fiscal policy is suitable, but the choice of increasing taxes, decreasing government expenditure or doing both simultaneously is mostly political The AD/AS model shows that increasing taxes is the best fiscal policy available. The AD/AS model shows that decreasing government expenditure is the best fiscal policy available.
