Dear Professor Cram, 

I need your advise. Business sells items. 25% customers pay next month. For Oct. cash collected was $21000 and $6500(accounts receivable) from Sept. Total-27500. What is revenue in this case?

Thank you,

Luiza

___________________

If you are on cash basis accounting, this is simply the $27,500 received in the month.

However, I expect you are on accrual basis, in which case the sales made in the month are what you want to count instead of the cash received. Under accrual, you sold $21,000 that you already collected on, and another 25% that will be collected the following month. Therefore, the $21,000 is 75% of revenue for the month. Now it becomes an algebra problem:

$21,000/.75 = $28,000 

The $6,500 of accounts receivable is the 25% of the prior month's revenue, so it doesn't count for this month.

Good studying!

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!

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.

Scarcity of resources necessitates trade-offs, and trade-offs result in an opportunity costs.  Any decision that involves a choice between two or more options has an opportunity cost. 

The concept of ‘opportunity costs’ can be shown by using a Production Possibility Curve.  The Production Possibility Curve depicts the best possible combinations of two or more goods an economy can produce using all of the available resources.  It shows the trade-off between more of one good in terms of another.  The law of increasing opportunity costs is reflected in the shape of the Production Possibility Curve.  The curve is bowed out, which shows that when an economy wants to produce more of one product it must give up successively larger amounts of the other products it makes.  The slope of the curve conveys the trade-off in terms of opportunity cost of producing one good rather than another.  

Resources are not all the same.  For example, if an economy was producing say motor vehicles and nuts, some of its resources will be better suited for producing motor vehicles while others are better suited for gathering nuts.  Some people (resources) will be really good at gathering nuts, for example people who love to be outdoors instead of indoors, while others like to work inside on cars.  In large economies if we started to withdraw resources from one product for another product, eventually we would reassign those whose opportunity costs are highest, which shows the general principle that when resources have different costs, we should always exploit the resource with the lowest opportunity cost first.  This is called the ‘low hanging fruit principle’ which says when expanding the production of any good, first employ those resources with the lowest opportunity cost, and only afterward turn to resources with higher opportunity costs.

Because resources are not equally productive in all possible uses, shifting resources from one use to another brings the law of increasing opportunity costs into play.  The production of additional units of one product requires the sacrifice of increasing amounts of the other products so a society should first employ those resources that are relatively efficient at producing that good, only afterward turning to those that are less efficient.

I can't figure out how you find the break-even quantity with a mixed cost. Here is the problem:

LOST sponsors a 5-day camping trip. LOST provides a $3,000 grant and collects $350 per camper. The program expects 150 campers and the following expenses: Campground fees, $6,500 for 3 days, Transportation fees $3925 with 60 person capacity, Outdoor equipment rental $45 per camper, meals $55 per camper per day. Determine the break-even number of campers.

Can you help?

You may not be surprised to learn that I went to visit my mother in December. She is 85 and doesn't do much cooking these days. I was surprised by a new peanut butter "cookie" recipe she had baked. I liked it so much, she sent the batch home with me. And she gave me the recipe. These Peanut Butter Cookie Biscotti Sticks are a simple but tasty snack. Now it is your turn to post a favorite recipe in your notebook.
