ok,I think I understand your graph description. The three curves are isoquants, showing the mix of L and C that could be combined to produce a particular level of output. The three straight lines are budget constraints, showing the amounts of L and C that could be used given a...

The answer to your first question is no. Find in your text book some explanation of Multipliers. Without going into detail, the government spending multiplier is 1/mps, while the taxation multiplier is (1/mps - 1) Remember, MPC+MPS=1. So, with an MPC=.9, MPS=.1. So the ...

It seems you have answered your own question. Economic efficiency occurs when MPx/MPy = Px/Py. So, in your example, use more k and less l. Repost if you are still confused.

Peak-load pricing is recognition that the demand for some service is greater at certain times compared to others. That is the, demand curve keeps shifting in and out, depending on the time. The seller, recognizing this shifting, adjusts his prices accordingly to maximize ...

Tough question. I believe the statement is false. For a perfect price-discriminating monopolist, the demand curve is also the MR curve. This monopolist does not get the same from each person. For the first person, the U gets the highest willingness to pay (P1). For the second ...

Microeconomics
Not profit maximizing. At the minimum of the AC curve it must be true that MC=AC. So, MC=\$50 and MR =\$60. The firm could do better by producing more as the marginal revenue from selling one more unit exceeds the marginal cost of producing that extra unit.

For a monopolist, marginal revenue is declining. The MR line can cross the MC line if MR is declining faster than MC.

Ms Sue's statement is correct. However I would add the following. A firm should hire until the value of the marginal product (aka marginal revenue product or MRP) equals the marginal cost of the input (aka the marginal factor cost or MFC). The MRP will decline because of ...

Start with three concepts or laws. 1) people are profit maximizers. 2) law of diminishing returns (eventuall) kicks in (MC rises) 3) law of demand applies. That is, people purchase more at lower prices than at higher prices. (MR is flat or declining) If you are in the business...

Economics are these correct
1) c is correct. (Mostly semantics, but a change in supply is a shift in the supply curve, a change in quantity supplied is a movement along a curve. 2) go with b. (hint: draw supply and demand curves for DVD's. An increase in DVD Players does what to the Demand for DVD&#...

[Urgent] Economics - GDP
GDP in 2000 is P*Q using 2000 prices and quantities. SO GDP in 2000 is 200*1 + 50*20 + 8*100 real GDP in 2001 is P*Q using 2000 prices and 2001 quantities. so Real GDP01 = 250*1 + 30*20 + 10*100

I think the correct answer is B. For A, income goes from 28000 to 30800, a change of 2800. Since the new income is between 30000 and 50000, the mtr is 20%. Of the change in income of 2800, 2000 was taxed at the 10% rate and the remaining 800 was taxed at the 20% rate. So, .1*...

MRTS is the marginal rate of technical substitution. In a two-input production function, it is simply the marginal product of X over the marginal product of Y. That is MRTS = -MPx/MPy and MPx is simply the first derivitive of the production function with respect to x

To solve, I rewrote the supply and demand equations as W=f(Q). So: Ws = Qs/5 and Wd = 6 - Q/5. (So far, this is just algebra) Now then, the \$1 per worker subsidy has the effect of lowering the supply equation by \$1 for all levels. So, Ws' = Qs/5 - 1. Now set supply = ...
