Economics
I would go with marginal utility per dollar as it can be used to guide the consumer to allocate is dollars of income to maximize utility. Although, truth be said, whenever I think of "marginal utility", I presume it means "marginal utility per dollar"

Statistics
Regression analysis is a statistical procedure used to find the relationship between a dependent variable and one or more independent variables. Multiple regression analysis requires there be two or more independent variables. Under a logit regression, the dependent variable i...

I dont get it either unless you can assume that the central bank views a 10% interest rate as "da bomb" and will always take action to keep the interest rate at 10%. In which case, you could solve these problems with simple algebra and plug in 0.1 for i.

Econ
I dont understand why depreciation is in the equation. I think of depreciation as the degradation of a physical asset over time. Depreciation affects interest rates in a round-a-bout way. That said, is it possible that 0.10 is the depreciation rate and 1/E-1 is the foreign int...

a) correct. b) the "imports" part of the equation is .25(Y-8). So the MPCF is .25 Alone, I dont think there is enough information to determine the MPCH -- Unless you can use the overall consumption function from a). If so, the MPCH=.75-.25 = .50 c)correct d) D=C+I+G+...

While I am a bit familiar with the Cournot model, I do not know what you mean by "strategies 1 to 5" The basic Cournot model that I know assumes that each player assumes the positions of the other players are fixed, and so each player maximizes accordingly. This iter...

International Economics
This is the easy part of your question. Draw initial world-market supply and demand curves for tobacco; and another for domestic food items. If the US subsidises foreign tobacco farmers, foreign tobacco farmers produce more, causing the price for tobacco to fall, causing US pr...

Trade is win-win; both trading partners are better off. This is true for domestic as well as international. Unless you are a pure Marxist, some the gains from trade must trickle down to workers.

There are a whole host of reasons why the daily market price of a stock will fluctuate around a stock's "proper" or "intrinsic" price. First, is the definition or determination of a stock's "proper" price. A stock's price is not based ...

An EXCEL spreadsheet is very helpful for solving these type of problems. write out spaces for 7 numbers. 1) the Median is 16, so put 16 in the 4-spot. 2) the sum of the first two spots (two lowest) is 18 -- the mode. Since you need 3 odd numbers, try 7 and 11 in the spots 1 an...

National output, aka GNP, is the sum of C+I+G+(X-M) (X-M is net exports). So, for each scenario, decide how one (or more) of the above factors would change. A fall in interest rates should spur investments (I), an appreciation of the home currency should make imports cheaper a...

You probably have a demand function or table, which shows price (P) and the quantity demanded (Q). Total revenue is simply P*Q. You also probably have some supply function or table, which shows the average and/or marginal costs of producing each level of Q. Average cost*Q = to...

First, lets break apart the Utility function. We know Aneeta consumes 15 x and 10 y. Her utility is therefore min(4*15, 2*15+10) = min(60, 40) = 40. So, for here relevant consumption pattern, her utility function is simply U=2x+y. Utility will be maximized when MUx/MUy = Px/Py...

Right. I was a bit confuse by your terminology. I missed the word "real" While the exchange rate may not be unity (one-to-one), the REAL exchange rate would be unity.

I dont know what your "Grapher tool" is. That said, if the economy has zero inflation and 5% unemployment for several years, that sounds like equilibrium to me. Any attempts to move to an alternative position is, very likely, doomed to fail.
