Inflation and Forest Investment Analysis
What’s real?
![Page 2: Inflation and Forest Investment Analysis](https://reader036.fdocuments.net/reader036/viewer/2022081515/56816291550346895dd2fff6/html5/thumbnails/2.jpg)
What’s Inflation• An increase in prices that makes a “market
basket” of goods and services more expensive over time.
• Basket costs $1,400 in 2003 and $1,550 in 2004, a one year period.– Increase in cost is $150– % increase, the annual rate of inflation, is
• $150/$1,400 = 10.7%, or• ($1,550/$1,400)1/1 – 1 =1.107 – 1 = 10.7%

Causes of Inflation
• Demand-pull inflation– Too many people chasing too few goods and services
• Cost-push inflation– Costs of factors of production rise, pushing up prices
of goods and services• Monetary inflation
– Government “prints” more money, leading to demand pull inflation

Terminology• Price with inflation included
– Nominal– Current dollar– Inflated– Actual
• Price with inflation not included– Real– Constant dollar– Deflated– Relative

Nomenclature• f = annual inflation rate• r = real interest rate• i = inflated or nominal interest rate
i = (r + f + rf)• In = inflated or nominal dollar value in
year n• Vn = future value in year n, in constant
dollars of year 0

Average Annual Rate of Inflation
• Rate of inflation between two points in time more than one year apart.
• Calculate as, f = (Vn/V0)1/n -1 = (155.4/32.5)1/48 – 1 = 4.780.02083 – 1 = 1.0331 – 1 = 3.31% per annum
![Page 8: Inflation and Forest Investment Analysis](https://reader036.fdocuments.net/reader036/viewer/2022081515/56816291550346895dd2fff6/html5/thumbnails/8.jpg)
Converting the value of an asset from its nominal to its real value
• Vn = In/(1+f)n • Example – Timberland is purchased for
$500 per acre in 1957. In 2005 it’s sold for $3,500 per acre. If average annual inflation over this period is 3.31%, what is the sale price of the land in terms of 1982 values?V2005 = $3,500/1.033148 = $733.22
• What is the real rate of return on the land?r = ($733.22/$500)1/48 – 1 = 0.008

Nominal and Real ROR’s
Loan $100 now to be returned in one year. You want a 5% real rate of return, r, i.e. 5% more than inflation. If inflation will be 4% over the year you need $104 back just to keep same purchasing power of $100.
$100 (1+f)n = 100 (1.04)1 = $104To get 5% return need to multiply $104 by (1+r)n, $104 (1.05)1 = $109.20
![Page 14: Inflation and Forest Investment Analysis](https://reader036.fdocuments.net/reader036/viewer/2022081515/56816291550346895dd2fff6/html5/thumbnails/14.jpg)
Nominal and Real ROR’sCombining the steps,
Calculate current or inflated value is,In = V0 (1+r)n (1+f)n
= V0 (1+ r + f + rf)n = V0 (1+i)n,therefore,
i = r + f + rf = 0.05 + 0.04 + 0.05*0.04 = 0.09 + 0.002 = 0.092,
or, i = (1 + r) (1 + f) -1
![Page 15: Inflation and Forest Investment Analysis](https://reader036.fdocuments.net/reader036/viewer/2022081515/56816291550346895dd2fff6/html5/thumbnails/15.jpg)
Nominal and Real ROR’s
If you know the nominal rate of return and inflation rate, solve for the real rate of return,
(1 + r) (1 + f) = 1 + i1 + r = (1 + i) / (1 + f) r = [(1 + i) / (1 + f)] - 1
![Page 16: Inflation and Forest Investment Analysis](https://reader036.fdocuments.net/reader036/viewer/2022081515/56816291550346895dd2fff6/html5/thumbnails/16.jpg)
Calculating Inflation Adjusted PV’s
PV0 = In/(1+i)n
= [Vn (1+f)n] / (1+r+f+rf)n
= [Vn(1+f)n]/[(1+r)n(1+f)n]
= [Vn(1+f)n]/[(1+r)n(1+f)n]
= Vn/(1+r)n
![Page 17: Inflation and Forest Investment Analysis](https://reader036.fdocuments.net/reader036/viewer/2022081515/56816291550346895dd2fff6/html5/thumbnails/17.jpg)
Calculating Inflation Adjusted PV’s
• Guidelines for computing net present value (NPV)– If future cash flows are in constant dollars
compute NPV with a real interest rate, r– If future cash flows are in current dollars
compute NPV with a nominal interest rate. Use same inflation rate in the cash flows and nominal interest rate
![Page 18: Inflation and Forest Investment Analysis](https://reader036.fdocuments.net/reader036/viewer/2022081515/56816291550346895dd2fff6/html5/thumbnails/18.jpg)
Warning
•Never mix real dollars and nominal dollars in the same equation
![Page 19: Inflation and Forest Investment Analysis](https://reader036.fdocuments.net/reader036/viewer/2022081515/56816291550346895dd2fff6/html5/thumbnails/19.jpg)
Recommendation
• It’s usually easier to work in real terms, that is adjust all cash flows to real values, and discount with real interest rate, r
• However, have to use nominal values for after-tax calculations,– Tax laws generally don’t adjust rates for
inflation, and never adjust basis of assets for inflation
![Page 20: Inflation and Forest Investment Analysis](https://reader036.fdocuments.net/reader036/viewer/2022081515/56816291550346895dd2fff6/html5/thumbnails/20.jpg)
Income tax on gain from disposal of assets
C = basis of asset In = nominal value in year nTi = tax rate (5% or 15%)
Tax due = Ti (In – C)
![Page 21: Inflation and Forest Investment Analysis](https://reader036.fdocuments.net/reader036/viewer/2022081515/56816291550346895dd2fff6/html5/thumbnails/21.jpg)
ExampleGeorge buys timberland in 1975 for $120,000 of which $80,000 is attributable to merchantable timber. In 1980 he sells 20% of the merchant-able timber for $50,000. What is the tax on the sale?C = 0.2 * $80,000 = $16,000I80 = $50,000Ti = 15%Tax due = 0.15 ($50,000 - $16,000)
= 0.15 * $34,000 = $5,100
After-tax gain = $50,000 - $5,100 = $44,900
![Page 22: Inflation and Forest Investment Analysis](https://reader036.fdocuments.net/reader036/viewer/2022081515/56816291550346895dd2fff6/html5/thumbnails/22.jpg)
Tax Basis
• Used to determine gain or loss on the “disposal” of an asset
• How’s basis determined?– Purchased assets – acquisition cost– Gift – basis of donor used by donee
(carryover basis)– Inheritance – fair market value on deceased
date of death (stepped-up basis)
![Page 23: Inflation and Forest Investment Analysis](https://reader036.fdocuments.net/reader036/viewer/2022081515/56816291550346895dd2fff6/html5/thumbnails/23.jpg)
After-Tax NPV
Vn – Ti [Vn – C/(1+f)n]NPV =
(1+r)n
Vn – Ti Vn+ Ti (C/(1+f)n
NPV = (1+r)n
![Page 24: Inflation and Forest Investment Analysis](https://reader036.fdocuments.net/reader036/viewer/2022081515/56816291550346895dd2fff6/html5/thumbnails/24.jpg)
After-Tax NPV, Example
Buy an asset for $2,000 and sell it 8 years for $8,000. Annual inflation rate is 9.05%.
f = 0.0905, r = 0.05Ti = 0.30I8 = $4,000*1.09058 = $8,000
$4,000 – 0.30[4,000 – 2,000/(1.09058)]NPV =
(1.05)8 = $2,098
![Page 25: Inflation and Forest Investment Analysis](https://reader036.fdocuments.net/reader036/viewer/2022081515/56816291550346895dd2fff6/html5/thumbnails/25.jpg)

After-Tax NPV With No Inflation
$4,000 – 0.30 ($4,000 – $2,000)NPV =
(1.05)8 = $2,301
Decrease in after-tax NPV due to inflation is,$2,301 - $2,098 = $203

Affect of Inflation on Series Payment Formulas – annual and periodic
• Basic formulas assume fixed payments
• If payments are fixed in nominal terms must use nominal interest rate, i, in series payment formulas.
• If nominal payments rise at exactly the inflation rate, they are fixed in real terms and must use real interest rate in formulas.
