ECON 466 - KEY TO PROBLEMS AT END OF CHAPTER 12

CONTROLLING FARM LAND

Problem 12.3:

To obtain the appraisal value of land, use formula (12.1):

(12.1) V0 = P0/it

with: P0 = $80 per acre per year

it = 0.04762 per year

V0 = 80/0.04762 = $1,680 per acre

The real interest rate it is obtained from expression (11.3) in Chapter 11:

(11.3) 1 + i = (1 + it) (1 + if)

with: i = 0.10 per year

it = ?

if = 0.05 per year

1 + 0.10 = (1 + it) (1 + 0.05)

1 + it = 1.10/1.05

it = 1.04762 - 1 = 0.04762

The anticipated value j years into the future can be calculated from a generalization of formula (11.8) in Chapter 11 (see solution to Problem 11.6 at end of Chapter 11):

(11.8) Vj =

= V0 (1 + if)j

Hence, the anticipated values one and two years into the future are, respectively,

V1 = (1,680) (1 + 0.05) = $1,764 per acre

V2 = (1,680) (1 + 0.05)2 = $1,852 per acre

That is, the nominal value of land is anticipated to increase at the inflation rate.

Problem 12.4:

To calculate the appraisal value of land with nonzero real growth in expected cash rent, apply formula (12.4):

(12.4) V0 =

with: P0 = $80 per acre per year

g = 0.01 per year

it = 0.04762 per year

V0 = = $2,148 per acre

From equation (12.8):

(12.8) it = + g

= (real current rate of return) + (real rate of capital gain)

Real current rate of return =

= = 0.03762 per year

Real rate of capital gain = g

= 0.01 per year

In other words, the 4.762% annual real rate of return on the land investment is due to a 3.762% of annual real current rate of return and a 1% annual rate of real capital gain.

Problem 12.5:

In this problem, the solution is as in Problem 12.4 but with g = -0.01 per year (instead of g = 0.01 per year):

V0 = = $1,375 per acre

Note that the appraisal value of land increases as the expected growth in real cash rent goes up (compare the V0s obtained in Problems 12.3, 12.4, and 12.5).

Problem 12.6:

To evaluate the profitability of the investment in land, use formula (12.10):

(12.10) NPV = -INV + + + ... + +

with: INV = $2,000 per acre

P1 = P2 = … = PN = A = $120 per acre per year

i = 0.05 per year

t = 0

N = 10 years

VN = $2,000 per acre

TN = (VN - INV) t = (2,000 - 2,000) (0) = $0

NPV = -2,000 + (120) [USPV0.05,10] +

= -2,000 + (120) (7.7217) + 2,000 (0.6139) = $154 per acre

The investment is acceptable because NPV = $154 > 0.

Problem 12.7:

In the presence of anticipated price changes, the profitability of the land investment can be calculated by employing the formulas in Table 12.2:

NPV = -INV + + + ... +

+

= -INV + (1 - t) P0 [USPVr,N] +

where: gP = anticipated rate of growth in nominal cash flows

gl = anticipated rate of growth in nominal land values

r = (i - gp)/(1 + gp)

The nominal interest rate i is obtained from expression (11.3) in Chapter 11:

(11.3) 1 + i = (1 + it) (1 + if)

In this particular problem, the values to use are:

INV = $2,000 per acre

P0 = $120 per acre per year

it = 0.05 per year

if = 0.06 per year

gp = 0.06 per year

gl = 0.06 per year

t = 0

N = 10 years

NPV = -2,000 + (120) [USPV0.05,10] +

= -2,000 + (120) (7.7217) + 2,000 (0.6139) = $154 per acre

The investment is acceptable because NPV = $154 > 0.

This example is very special in that inflation does not affect the NPV (compare the solutions of Problems 12.7 and 12.6). The reasons for this result are that (i) the inflation rate, the rate of growth in nominal cash flows, and the rate of growth in nominal land values are assumed to be the same (i.e., if = gp = gl), and that (ii) the tax rate is zero (t = 0). In general, however, inflation will affect NPVs (see, for example, Problems 12.8 and 12.9 below).

Problem 12.8:

This problem is solved as Problem 12.7 but employing gl = 0.05 per year (instead of gl = 0.06 per year):

NPV = -2,000 + (120) [USPV0.05,10] +

= -2,000 + (120) (7.7217) + 2,000 (0.5584) = $43 per acre

The investment is acceptable because NPV = $43 > 0.

Problem 12.9:

The solution to this problem is obtained as for Problem 12.7, but using t = 0.20 (instead of t = 0):

NPV = -2,000 + (1 - 0.20) (120) [USPV0.05,10] +

= -2,000 + (96) (7.7217) + {(2,000) (1.7908) - [(2,000) (1.7908) - 2,000] (0.20)} (0.6139) (0.5584)

= -$139 per acre

The investment is not acceptable because NPV = -$139 < 0.

Problem 12.10:

The formula to apply in order to solve this problem is (12.15):

(12.15) NPV = -INV + + + ... +

- - - ... -

+

= -INV + (1 - t) P0 [USPVr,N] - - - ... -

+ + -

where: gP = anticipated rate of growth in nominal cash flows

gl = anticipated rate of growth in nominal land values

r = (i - gp)/(1 + gp)

The nominal interest rate i is obtained from expression (11.3) in Chapter 11:

(11.3) 1 + i = (1 + it) (1 + if)

The values to use for this particular problem are:

INV = $2,000 per acre

INVdp = (2,000) (0.20) = $400 per acre

P0 = $120 per acre per year

it = 0.05 per year

if = 0.06 per year

gP = 0.06 per year

gl = 0.06 per year

t = 0.20

N = 10 years

Then:

(1 - t) P0 [USPVr,N] = (1 - 0.20) (120) [USPV0.05,10] = (96) (7.7217) = 741

= = (1,600) (0.6139) = 982

= = (400) (0.6139) (0.5584) = 137

In order to determine the principal outstanding (Dn), and the principal (Prn) and interest (In) amounts of each annual loan repayment, the easiest procedure is to calculate first the amount of each annual loan repayment by means of the annuity formula (9.5) in Chapter 9:

(9.5) D0 = Aloan []

with: D0 = (2,000) (1 - 0.20) = $1,600 per acre

Aloan = ?

iloan = 0.11 per year

Nloan = 30 years

Aloan = D0/[USPV0.11,30] = 1,600/8.6938 = $184 per acre per year

The principal outstanding at each period (Dn) is the present value (as of that period) of the future annual payments, which can be calculated using the annuity formula (9.5) in Chapter 9:

(9.5) Dn = Aloan []

where n denotes the period at which the outstanding principal is to be calculated. Here:

Period 0: D0 = (184) [USPV0.11,30] = (184) (8.6938) = $1,600

Period 1: D1 = (184) [USPV0.11,29] = (184) (8.6501) = $1,592

Period 2: D2 = (184) [USPV0.11,28] = (184) (8.6016) = $1,583

Period 3: D3 = (184) [USPV0.11,27] = (184) (8.5478) = $1,573

Period 4: D4 = (184) [USPV0.11,26] = (184) (8.4881) = $1,562

Period 5: D5 = (184) [USPV0.11,25] = (184) (8.4217) = $1,550

Period 6: D6 = (184) [USPV0.11,24] = (184) (8.3481) = $1,536

Period 7: D7 = (184) [USPV0.11,23] = (184) (8.2664) = $1,521

Period 8: D8 = (184) [USPV0.11,22] = (184) (8.1757) = $1,504

Period 9: D9 = (184) [USPV0.11,21] = (184) (8.0751) = $1,486

Period 10: D10 = (184) [USPV0.11,20] = (184) (7.9633) = $1,465

The interest payment at each period (In) is the product of the loan interest rate (iloan) by the loan's outstanding principal in the previous period (Dn-1):

In = iloan Dn-1

Period 1: I1 = (0.11) (1,600) = $176

Period 2: I2 = (0.11) (1,592) = $175

Period 3: I3 = (0.11) (1,583) = $174

Period 4: I4 = (0.11) (1,573) = $173

Period 5: I5 = (0.11) (1,562) = $172

Period 6: I6 = (0.11) (1,550) = $170

Period 7: I7 = (0.11) (1,536) = $169

Period 8: I8 = (0.11) (1,521) = $167

Period 9: I9 = (0.11) (1,504) = $165

Period 10: I10 = (0.11) (1,486) = $163

The principal payment at each period (Prn) is equal to the loan's annual installment (Aloan) minus the interest payment at that period (In):

Prn = Aloan - In

Period 1: Pr1 = 184 - 176 = $8

Period 2: Pr2 = 184 - 175 = $9

Period 3: Pr3 = 184 - 174 = $10

Period 4: Pr4 = 184 - 173 = $11

Period 5: Pr5 = 184 - 172 = $12

Period 6: Pr6 = 184 - 170 = $14

Period 7: Pr7 = 184 - 169 = $15

Period 8: Pr8 = 184 - 167 = $17

Period 9: Pr9 = 184 - 165 = $19

Period 10: Pr10 = 184 - 163 = $21

Therefore:

= = (149) (0.9524) (0.9434) = 134

= = (149) (0.9070) (0.8900) = 120

= = (149) (0.8638) (0.8396) = 108

= = (149) (0.8227) (0.7921) = 97

= = (150) (0.7835) (0.7473) = 88

= = (150) (0.7462) (0.7050) = 79

= = (150) (0.7107) (0.6651) = 71

= = (151) (0.6768) (0.6274) = 64

= = (151) (0.6446) (0.5919) = 58

= = (151) (0.6139) (0.5584) = 52

= = (1,465) (0.6139) (0.5584) = 502

Substitution of the preceding values in (12.15) yields:

NPV = - 400 + 741 - 134 - 120 - 108 - 97 - 88 - 79 - 71- 64 - 58 - 52 + 982 + 137 - 502 = $88 per acre

The land investment with borrowing is acceptable because NPV = $88 > 0.

Solving this problem by hand is extremely tedious and provides no additional insight. Therefore, it is strongly recommended to use a computer spreadsheet (e.g., Lotus 123, Excel, Quattro Pro) to find the NPV. Such a spreadsheet might look like Table 12.1 below.

Table 12.1: Excel spreadsheet to solve for net present value of land investment.



Problem 12.11:

The land investment in Problem 12.10 is profitable but not feasible because it has negative cash flows for the first seven years of the investment. In other words, the cash returns from land are not sufficient to repay the loan and pay for taxes until year 8. The investor should either have other sources of cash to cover for the cash shortages originated by the land investment in the first seven years. Alternatively, feasibility could be achieved by changing the terms of the loan, for example, reducing the loan interest rate, lengthening the loan maturity, making a balloon payment at year 10, and/or postponing principal repayment.

The enclosed Table 12.2 shows the effect of changing the interest rate on the loan to 7% (as opposed to 11%), whereas Table 12.3 depicts the impact of a loan with 40 years to maturity (as opposed to 30 years). It can be seen that feasibility is achieved practically by getting a loan interest rate of 7%. Lengthening the loan maturity to 40 years improves the cash flow situation, but is not enough to achieve feasibility. It is important to note that these alternative loan arrangements will generally change the profitability of the investment.

Problem 12.13:

Note that, according to the data in Problem 12.6, there is neither inflation (if = gp = 0), nor taxes (t = 0), nor external financing (INV = INVdp). Hence, the maximum bid price (INV) can be obtained by means of the simple formula (12.19):

(12.19) INV =

where from (11.3):

(11.3) 1 + i = (1 + it) (1 + if)

with: A = $120 per acre per year

it = 0.05 per year

if = 0 per year

gl = 0 per year

N = 10 years

INV = = = $2,400 per acre

Given the data in Problem 12.6, the maximum bid price the investor can afford to pay is $2,400 per acre. This price is consistent with the results from Problem 12.6, where it was found that the land investment with a price of $2,000 per acre was profitable.

To find the maximum bid price for the data given in Problem 12.7, it is no longer possible to use the simple formula (12.19). In this case, the solution can be obtained by means of the formulas in Table 12.2:

NPV = -INV + + + ... +

+

= -INV + (1 - t) P0 [USPVr,N] + INV []

where from (11.3):

(11.3) 1 + i = (1 + it) (1 + if)

with: NPV = $0 per acre

INV = ?

P0 = $120 per acre per year

it = 0.05 per year

if = 0.06 per year

gp = 0.06 per year

gl = 0.06 per year

t = 0

N = 10 years

r = (i - gp)/(1 + gp)

0 = -INV + (1 - 0) (120) [USPV0.05,10] + INV []

0 = -INV + (120) (7.7217) + INV []

INV - 0.6139 INV = 926.604

INV = = $2,400 per acre

Therefore, the maximum bid price the investor can afford to pay is $2,400 per acre. This price is consistent with the results from Problem 12.7, where it was found that the land investment with a price of $2,000 per acre was profitable. Note also that the maximum bid price is the same as for the data in Problem 12.6 because, as discussed in the solution to Problem 12.7, in this particular example inflation does not affect the investment's profitability.

Problem 12.19:

To see how land values should respond to changes in different variables, use formula (12.4):

(12.4) V0 =

a. V0 as P0

b. V0 as g

c. V0 as it
