20) This OG is a long run dude, not into booms or busts.
21) The RBC’s (Real Business Cycles) has this homeslice
22) These three have all been in the KTP’s (Keynesian
Theory Posse)
23) P-Cubed’s wing-man, he’s got his back (P-Cubed =
PPP)
24) When P-Sticky joined the KTP’s (Keynesian Theory
Posse), this one was jumped-in next.
25) When this dude is down, the economy may enter a
recession
26) Coriorgornx uses this handle (street name).
Answers:
1) d. the unemployment rate is the fraction of the labor
force that is actively searching for work. It does not
include people who are outside the labor force.
2) e. frictional unemployment results from a changing
economy where in the time it takes someone to find a job,
someone probably lost theirs (and lost it unrelated to the
person finding a job).
3) c. With an equilibrium and no surplus of labor,
unemployment rate should be zero.
4) b. Frictional unemployment model assumes that job
search takes time. And the longer it takes to find a job,
the greater the average number of people unemployed
5) e. Exports – Imports is net exports which is also our
trade balance. And the trade balance has to equal net
foreign investment which is called "net capital outflow."
6) c. If the RER < 1, it means you get fewer foreign
goods in exchange for domestic goods. So we should
continue to buy domestic and not buy foreign. What is
economical for us is also economical for foreigners.
They too should buy our goods.
7) c. Interest rates are the hidden part of aggregate
demand, and as interest rates change, prices and demand
change.
8) e. Demand decreases, and in the short run, supply will
drop to match the drop in demand.
9) a. Keynesian theory uses sticky prices (or wages or
other) which means that prices can’t fully adjust in the
short run to a change in AD. This creates a
disequilibrium (surplus or shortage) which causes the
short term economic fluctuation.
10) c. Real business cycle theory suggests that short run
economic fluctuations occur because of changes in
resources
11) b. Misperception theory has businesses mistaking
unexpectedly high inflation as an increase in price and
demand for just their product and thus responding by
producing more.
12) e. All three theories attempt to explain short run
economic fluctuations, including recessions.
13) d. Both the Keynesian and Misperception theory
explain economic fluctuations as the result of changes in
aggregate demand.
14) a. Keynesian theory uses the idea of something
(prices, for example) being sticky so the economy can be
in a disequilibrium in the short run.
15) a. Keynesian theory is the oldest of the three. It was
developed during the Great Depression. The other two
theories were developed in the 1970’s & 1980’s.
16) c. Real Business Cycle theory says that economic
fluctuations are a result of short run changes in
productive resources. These sudden changes in resources
are sometimes called “supply shocks.”
17) b. Misperception theory is based on the idea of
people confusing macro price movements with micro
demand changes.
18) d. Both Keynesian and Misperception theory can
explain why a recession results from a drop in AD, which
would include a drop in C or I (or G or NX).
19) e. Aggregate da man (demand) is C+I+G+NX or GIce nX
20) c. Long run unemployment is the Natural Rate
(Natch R.L. Rat)
21) d. Supply shocks are part of the Real Business Cycle
theory (Sup’ shocks)
22) e. a. f. Keynesian theory uses drops in AD (drop in
G-Ice nX) coupled with sticky prices (P-Sticky) which
creates a disequilibrium (Dis E. Q.).
23) b. If Purchasing Power Parity isn’t true, then
someone can make money, possibly, by buying where
prices are low and selling where they’re high which is
called arbitrage (R.B. Trag).
24) f. Sticky prices (P-Sticky) leads to a disequilibrium
(Dis E.Q.) in the short run when demand changes.
25) e. G-Ice nX are the elements of AD. When AD
drops, it can put the economy into a recession.
26) e. G-Ice nX is coriorgornx
