Refer to the above diagrams. The solid lines are production possibilities curves; the
dashed lines are trading possibilities curves. The trading possibilities curves suggest
that the terms of trade are:
A.1.5 beers for 1 pizza.
B.1 beer for 2 pizzas.
C.2 beers for 1 pizza.
D.1 beer for 1.5 pizzas.
13) Below are price level (PL) and output (Q) combinations to describe aggregate
demand and aggregate supply curves: (1) PL and Q1 are AD1. (2) PL and Q2 are AD2.
(3) PL and Q3 are ASLR1. (4) PL and Q4 are ASLR2.
(a)Use the graph below to graph AD1, AD2, ASLR1, and ASLR2. Label the vertical
axis as the price level and the horizontal axis as real output (Q).
(b)If the economy is initially in equilibrium where AD1 and ASLR1 intersect, what will
the price level and real output be?
(c)If over time, the economy grows from ASLR1 to ASLR2, what will be the
equilibrium price level and real output?
(d)Assume a monetary rule is adopted that increases the money supply proportionate to
the increase in aggregate supply. Aggregate demand will increase from AD1 to AD2, so
what will the equilibrium price level and real output be?
(e)Mainstream economists would argue that velocity is unstable, so a constant increase
in the money supply might not shift AD1 all the way to AD2. It might also be the case
that the constant increase in the money supply might shift AD2 beyond its expected
