If disposable income is 4,000, consumption is 3,500, government purchases is 1,000, and taxes minus transfers are 800, national saving is equal to ___.
Translate the givens into symbols, Y - T = 4000 and C = 3500. G = 1000 and T = 800. S = Y - C - G = (Y - T) - C - G + T = 4000 - 3500 - 1000 + 800 = 300
Paasche Index

factors of production and production function.
13. If the nominal interest rate is 1 percent and the expected inflation rate is 5 percent, the ex ante real interest rate is _-0.04_. (Enter your answer as a decimal.)
-0.04_
16. The quantitative easing policy conducted by the Federal Reserve between 2007 and 2011 resulted in a large increase in the monetary base that was partially offset by: A) a significant increase in the reserve-deposit ratio. B) a significant decrease in the reserve-deposit ratio. C) open-market purchases. D) open-market sales.

6. Assume that a firm is considering building a factory that will cost $5 million. It believes that it can get a profit from this factory of $600,000 per year for many years. The interest rate at which the firm can borrow money is 15 percent. After evaluating whether it should build the factory, the firm decides that it should: A) not build because the rate of return on the factory is only 6 percent. B) not build because the rate of return on the factory is only 12 percent. C) build because the rate of return on the factory is 30 percent. D) build because the rate of return on the factory is 35 percent.
B) not build because the rate of return on the factory is only 12 percent. The firm would pay 0.15($5,000,000) per year = $750,000 in interest which is more than it can earn in profit, so the firm would lose money after factoring in interest. Alternative you could view the factory as yielding a return of 600,000/5,000,000 = 0.12 or 12% which is less than the interest you are paying.

9. When Toyota sells a car manufactured in America from its inventory, GDP A) increases.B) decreases.C) is not changed. D) increases or decreases, depending on the year the product was produced.
C) is not changed. The car was manufactured sometime in the past and counted toward GDP at that time when it was put into an inventory (e.g. as investment).

3. In a neoclassical economy, assume that the government lowers both government spending and taxes by the same amount. This causes: A) investment to fall and the interest rate to rise. B) investment to rise and the interest rate to fall. C) investment and the interest rate to both fall. D) investment and the interest rate to both rise.
B) investment to rise and the interest rate to fall. Method #1: S = Y - C - G, and here G falls so S is probably rising. But this ignores that C is a function of T so you have to factor in that as T falls C will rise, partially canceling out the drop in G. But since it only partially cancels the change in G the net effect is an increase in S.Method #2: If G and T both fall by the same amount then Spub does not change. But since C is a function of T private savings, Spr = Y - C - T will change. If T falls by $100 then C will rise by 100xMPC < 100 and Spr will rise slightly.

Real money balances are defined as M/P. This name should make sense as it is analogous to the real wage (W/P), real rental price of capital (R/P), and real GDP(PY/P). If the GDP growth rate of a country is 8 percent and inflation is 4 percent, and the velocity of money remains constant, what is the change in real money balances?

The government raises lump-sum taxes on income by $100 billion, and the neoclassical economy adjusts so that output does not change. If the marginal propensity to consume is 0.6, the change in private saving is $____ billion. (For all of these numeric problems pay attention to the scale and don't type in the units. If you think the answer is $5 billion then just enter "5").
S = Y - C - T ∆S = ∆Y - ∆C - ∆T, note that ∆C = -(MPC)∆T ∆S = 0 + (MPC)∆T - ∆T ∆S = 0 + (0.6)(100 billion) - 100 billion = -$40 billion
Assume that the consumption function is given by C = 150 + 0.85(Y - T) and the tax function is given by T = t0 + t1Y. If t0 increases by 1 unit, then the change in consumption is ___. Notice that T is endogenous in this model—they depend on income—whereas in the basic model T was exogenous. (not to turn in: is this model of taxes, where they depend on income, more or less realistic than exogenous taxes?)
-0.85 If t0 increases by 1 unit then T increases by 1 unit and C drops by 0.85 units. If that is abstract just make up numbers for t0 and t1 and then try increasing t0 by 1 unit and seeing what happens to C.

For Cobb-Douglas 𝑴𝑷𝑲 = 𝜶𝒀/𝑲 (this is shown in the book and you should know it). Y = 100*1000.5*1000.5 = 10,000 and 𝜶 = 𝟎. 𝟓 (the exponent on K) so 𝑴𝑷𝑲 = 𝟎. 𝟓 × 𝟏𝟎, 𝟎𝟎𝟎/ 𝟏𝟎𝟎 = 50.
