4. General principles of pricing for higher-order goods
If, as the result of a change in tastes, the need for tobacco should disappear
completely, the first consequence would be that all stocks of finished tobacco
products on hand would be deprived of their goods-character. A further
consequence would be that the raw tobacco leaves, the machines, tools, and
implements applicable exclusively to the processing of tobacco, the specialized
labor services employed in the production of tobacco products, the available
stocks of tobacco seeds, etc., would lose their goods-character. The services,
presently so well paid, of the agents who have so much skill in the grading and
merchandising of tobaccos in such places as Cuba, Manila, Puerto Rico, and
Havana, as well as the specialized labor services of the many people, both in
Europe and in those distant countries, who are employed in the manufacture of
cigars, would cease to be goods. Even tobacco boxes, humidors, all kinds of
tobacco pipes, pipe stems, etc., would lose their goods-character. This apparently
very complex phenomenon is explained by the fact that all the goods enumerated
above derive their goods-character from their causal connection with the
satisfaction of the human need for tobacco. With the disappearance of this need,
one of the foundations underlying their goods-character is destroyed. [Menger,
5. General principles of pricing for higher-order goods
(cont.)
[This is the] general law of the determination of the value of a
concrete quantity of a good of higher order. Assuming in each
instance that all available goods of higher order are employed in the
most economic fashion, the value of a concrete quantity of a good of
higher order is equal to the difference in importance between the
satisfactions that can be attained when we have command of the
given quantity of the good of higher order whose value we wish to
determine and the satisfactions that would be attained if we did not
have this quantity at our command. This law corresponds exactly to
the general law of value determination. [Menger, Principles, pp. 164-
65]
6. Background: Austrian theory of imputation
âDefinition
âCharacteristics
â What is being priced: unit factor services
â Assignment of a good to an âorderâ is subjective (e.g., bread)
âComparison to other approaches
â Classical economists, Marx
â Neoclassical economics: assumptions of variable
proportions, profit maximization, and perfect competition
âSignificance
â Central to Misesian critique of socialism
Schumpeter (1942): feasibility of economic calculation under socialism
follows âfrom the elementary proposition that consumers in evaluating
(âdemandingâ) consumersâ good ipso facto also evaluate the means of
production which enter in the production of those goods.â
7. Rothbardâs approach to imputation
âLike neoclassical model: inputs (land, labor, capital),
outputs, profits, and losses
âSome unique aspects
â No cost curves
â Economic (causal-realist), not technological, explanation: emphasis
on means and ends (implies time and uncertainty)
â No assumptions about perfect competition in factor markets
â Emphasis on factor specificity, not merely variability, for marginal
productivity theory
â Explains prices of real-world, discrete factors (units of labor, capital
goods, etc.), not generic aggregate categories of âcapital,â âlabor,â
etc.
â Entrepreneur is present!
8. Rothbardâs approach to imputation (cont.)
âDiscounted marginal value product (DMVP = DMRP)
â Drop assumption of purely specific factors and consider
substitution across lines of production
â Money revenue attributed (âimputedâ) to one service unit of a
factor, discounted by social rate of time preference (i.e., pure
rate of interest)
â Establishes entrepreneurâs maximum willingness to pay for
one service unit of a factor.
â Given competitive bidding by entrepreneurs, ERE factor
prices (rents) will equal the factorâs DMVP â as long as the
factor is isolable.
â Variable proportions
â Nonspecific factors
Examples
9. Calculating DMRP and ERE price
âNonspecific factors 4A + 10B + 2C â $100
used in variable proportions: 3A + 10B + 2C â $80
MRP(A) = $20
P(A) = $20
10. Calculating DMRP and ERE price
âNonspecific factors 4A + 10B + 2C â $100
used in variable proportions: 3A + 10B + 2C â $80
MRP(A) = $20
P(A) = $20
âNonspecific factors 4A + 10B + 2C â $100
used in fixed proportions: 3A + 7.5B + 1.5C â $75
MRP(A) = $25
P(A) = no more than $25
11. Calculating DMRP and ERE price

P(A) = $20
âNonspecific factors 4A + 10B + 2C â $100

âAn indispensable 1A + 2B + 3C â $200

13. Böhm-Bawerkâs âlaw of costsâ
â Classical and Marxian versus Austrian
value theory
â Böhm-Bawerkâs law: prices of reproducible
goods, produced under competitive conditions,
tend to equal their money costs of production
â But, this doesnât mean that cost determines
price, because the âcostsâ are determined by
foregone utilities elsewhere in the economy!
â Distinction between proximate and ultimate
costs
