Another semester has come to a close, and with it some (hopefully) better grades.

So what are you doing this summer? If you're like most students, you might benefit from this post I wrote a couple of years ago about how to spend your summer vacation

For me, there's no rest for the wicked... We've enjoyed a doubling of usage in each of the past three semesters, and I aim to keep that trend going for the fall. I'm sitting in the local Starbucks right now, enjoying a too-large coffee and thinking of more cool and useful things to do with College-Cram.

Enjoy your summer!

Between wrapping up the spring semester and starting my summer "vacation" plans, I changed my profile page to include links to some of the most popular articles I've written over the years.

In case you hadn't seen them all, here they are:

Enjoy these, there are plenty more where they came from.

I'm doing this assignment and I'm totally lost,

U.S. :

d= 200 -40p

s= 40 +40p

Rest of the world:

d= 160 -40p

s= 80 +40p

The U.S. govenment imposes a quota of 32 units on its imports. Calculate the magnitude of deadweight loss resulting from the quota under the assumption that the U.S. is a small open economy?

If anyone knows about this it would great if you could help me out!

Every day, bunches of economics students searching for homework help because they're having trouble with economics end up at College-Cram.com. Sometimes the textbook is confusing and other times they just need some extra help, but either way we have a bunch of resources to help students get the economics homework help they need:

Try our resources and you'll find getting better grades in less time isn't that hard!

No, this isn't about Star Wars. We had some pretty serious thunderstorm activity pass through here early this morning with torrential rains, lightning strikes, tornados, and sporadic wind damage scattered throughout the area. While College-Cram is hosted by a major hosting company, unfortunately that company is located about 30 minutes north of us and was also caught in the same storm front.

The results, as some of you may have noticed, were some intermittent outages all day today.(I believe we were down about an hour total, in about four separate incidents.)

I applaud those of you who braved the elements and stuck with us, including Dzenana looking for Macroeconomics homework help on market equilibrium, and those who even managed to keep a sense of humor.  You're the real storm troopers.

I'm still not sure how the whole "college-cram" thing works, but if it might give me some help with the Macro project, I figured it's worth a try.

Here is the problem:

Eastland's currency is called the eastmark, and Westland's currency is called westmark. The supply of and demand for eastmark are given as:

Demand=25,000-5000e+50,000(Re-Rw)

Supply=18,500+8,000e-50,000(Re-Rw) where nominal exchange rate e is measured as westmarks per eastmarks, and Re and Rw are the real inerest rates prevailing in Eastland and Westland.

If Re=Rw=0.10 or 10%, what is market equilibrium value of the eastmark?

Any help, pointer, or anything that you can offer will be greatly appreciated.

Let cb = 0.2. Let the real money demand in the economy equal LD = 10 + 2Y – 8r.  The price level P is fixed at P = 1. Y is the level of output and r is the rate of interest.  What is the LM curve for this economy?

anyone help?

Dear Professor Cram,

Could you please answer the following question for me?

Suppose that the public holds a cash/deposit ration of  cp = 0.2, and the commercial banking sector holds a reserve/deposit ration of cb = 0.2.  The monetary base is given by H = 50.

Find the value of the money multiplier and the total amount of money in the economy. How does the money multiplier change if the central bank raises the reserve requirement to cb = 0.3? Briefly explain the economic reasoning for this change in the money multiplier.

____________

 

The Multiplier (M) for money is (1+Cp)/(Cp + Cb).

When Cp=0 the formula reduces to its simpler form of the inverse of reserves, or 1/ Cb.

For your question, we start with

Cp = 0.2 and  Cb = 0.2 so the multiplier is (1+0.2)/(0.2+0.2) = 1.2/0.4 = 3

The total money in the economy is M·H = 3·50 = 150

When the banking reserve requirement is increased to 0.3 the multiplier drops:

(1+0.2)/(0.2+0.3) = 1.2/0.5 = 2.4

This will reduce the total amount of money in the economy.

I hope this helps.

Good studying.

How about this one: 

“A given increase in the money supply will shift the LM curve farther to the right if money demand is more sensitive to the level of income”. True, false or uncertain? Briefly explain your answer.
Thanks, Katie

_____________

An increase in the money supply shifts the LM curve to the right, raising income and lowering the interest rate. It seems to me that if money demand is more sensitive to the level of income, this will reduce the shift of the LM curve to the right.

Dear Economics Community

Could you please answer me whether the following statement is true, false or uncertain and illustrate by graph please?

“Other things equal, an IS curve is steeper, the more sensitive consumption is to the rate of interest”. True, false or uncertain? Briefly explain your answer.

As I am stuck with some questions. I break them into topics. I hope you can respond to me quickly. Thanks, Katie
__________________

Katie,

This is a commonly asked question regarding the IS curve since it examines the very basis of the IS curve. The IS curve shows the combination of interest rates and national income that result in equilibrium in the goods market. The IS curve slopes downward because increases in the interest rate cause investment to fall, and thus reduce income through the multiplier:

(IS)    Y = C(Y, t) + I(i) + G + X(R) -M(R, Y), where R is the real exchange rate (eP* /P)


The slope depends of the responsiveness of investment to changes in the interest rate, and the magnitude of the autonomous investment multiplier. You plot Interest Rates on the Y-axis and National Income on the X-axis. Steepness then increases as the impact of interest rates decreases.

 

IS Curve 

Curve IS is not as steep as curve IS1. IS shows more impact on national income due to changes in interest rate, so LESS steepenss means MORE sensistivity.
