CR-Can somoene help

by gmat009 » Wed Sep 24, 2008 8:26 am
There are fundamentally two possible changes in an economy that will each cause inflation unless other compensating changes also occur. These changes are either reductions in the supply of goods and services or increases in demand. In a prebanking economy the quantity of money available, and hence the level of demand, is equivalent to the quantity of gold available.
If the statements above are true, then it is also true that in a prebanking economy
(A) any inflation is the result of reductions in the supply of goods and services
(B) if other factors in the economy are unchanged, increasing the quantity of gold available will lead to inflation
(C) if there is a reduction in the quantity of gold available, then, other things being equal, inflation must result
(D) the quantity of goods and services purchasable by a given amount of gold is constant
(E) whatever changes in demand occur, there will be compensating changes in the supply of goods and services

This is a tough one, but IMO: E

The passage states reductions in supply of goods and services OR increases in demand will cause inflation. It goes on further to state that in a prebanking economy, the supply of money AND demand are linked to the quantity of gold. Money in this instance is the goods and services.

I interpret this to mean as supply of gold goes up or down, supply and demand of money follows up or down, and vice versa. This movement negates inflation.

(A) is out of scope, it doesn't take into account the effects of increased demand

(B) goes against the conclusion

(C) sounds similar to (B) and goes against the conclusion

(D) is out of scope, the passage states there is a relationship between gold, goods and services, and demand. It also talks about "purchasing" goods and services which is not the main point of the passage.

What is the OA?

Looking for an explanation as well. I though (B) and (C) were saying the same things in a different way...

This is how I see it:

Fact 1: Increase in demand results in inflation (other things unchanged)

Fact 2: Quantity of gold available = level of demand

Increase in supply of gold increases demand, which in turn causes inflation.

demand = gold
more demand = inflation

Thus, more gold = inflation

(C) if there is a reduction in the quantity of gold available, then, other things being equal, inflation must result
(D) the quantity of goods and services purchasable by a given amount of gold is constant
(E) whatever changes in demand occur, there will be compensating changes in the supply of goods and services

pseudononymous has put it pretty simply and aptly. lets go sentence wise.

1. two possible changes that can result in inflation, provided other factors remain constrant.

2. a>> reductions in the supply of goods and services = inflation
b>> increases in demand = inflation

3. quantity of money available = level of demand = quantity of gold available.

Now, the 3rd sentence actually provides us with a completely new information (about quantity of gold) so in MUST BE TRUE question, we should find some answer choice that relates the new info to the old info.

A) any inflation is the result of reductions in the supply of goods and services - well, not exactly. sentence 1 tells us there could be inflation because of another factor - increase in demand

B) if other factors in the economy are unchanged, increasing the quantity of gold available will lead to inflation
now, going backwards from sentence 3, if quantity of gold increases >> level of demand increases >> quantity of money available increases
and fromsentence 2, as level of demand increases >> inflation increases

(C) if there is a reduction in the quantity of gold available, then, other things being equal, inflation must result
this is just the opposite. if quantity of gold available reduces >> level of demand decreases >> no inflation (see sentence 2)

(D) the quantity of goods and services purchasable by a given amount of gold is constant - no infor about the quantity of goods that are purchasable from gold

(E) whatever changes in demand occur, there will be compensating changes in the supply of goods and service
we know that changes in demand can result in inflation. but it might not be necessary that supply of goods and services is related to demand.

hoping it helps!!

I like the explanation on B
