‘Happy Are the Poor’: An Austrian Tale of Roundabout Production* By Hiroshi Ohta, Professor of Economics, Aoyama Gakuin University, Tokyo For Presentation at National Taiwan University Workshop on International Trade and Industrial Organization, November 1, 2008 ABSTRACT Economic development may not require capital-intensive methods of production. Using a simple Austrian model, we show that if labor productivity in the primary sector is low enough, roundabout methods of production become feasible. Moreover, it is the more labor-intensive methods that yield the greater final output. A higher labor productivity may appear to be geared to greater final output, all the more if combined with a higher output elasticity of capital under more capital-intensive roundabout methods of production. But when primary labor productivity is high enough (relative to the total factor productivity of final output) the roundabout methods become strictly inferior to the direct method. Thus, whenever roundabout methods are feasible, the more labor-intensive methods become superior to the more capital-intensive methods. If output elasticity of capital is large enough, labor-intensive methods become infeasible, and roundabout methods fail. *Preliminary draft not to be cited without author’s permission.

The difference is attributed to the absence (in Hong Kong) and the abundance (in India) of government planning and regulations. If Hong Kong is poorly endowed with natural resources, it was also even pitied as being over-populated. That is, what they have in abundance was deemed as of more liability than asset. Motivated by Hong Kong’s miraculous experience, the present article ponders conditions under which a very poor strictly inferior nation can not only catch up with, but also beat its apparent superior. Here we focus our attention on conditions more technological than institutional. We thus assume away government involvement in the present inquiry.1 This paper integrates, albeit in a very limited sense, Karl Marx and Boem Bawerk into a simple neo-classical synthesis. Addressed herein are the questions of production, the structure thereof, distribution, and related welfare. We start with the basic departure point thought that labor is the sole primary factor of production as is the case in both Marx and Boem Bawerk. We denounce Marxian labor theory of value insofar as it predicts exploitation of labor. This is not to say that we support Boem simply because he criticized Marx on grounds that rent on capital does not derive from exploitation of labor. It does not in fact. But that does not answer who, if anybody, is to be exploited by whom. We show 1 Even if government-planned, hasn’t such a heavily capital-intensive development as in India had some positive impact on economic growth? If the Austrian roundabout methods of production require a more capital-intensive than labor-intensive structure of production, then the government plan along that line itself may not be to blame at least? If private sectors are let alone, then their roundabout methods freely chosen could have been more labor intensive than capital intensive. The present paper shows indeed the technological conditions under which the roundabout methods of production require more labor-intensive methods than capital-intensive methods, while assuming away government. 2 that any seeming rent on capital shall be dissipated, and fully paid out to workers. The same wage payment made in the final consumption goods sector must be paid out elsewhere, too, so that it can even exceed average labor productivity in the capital good sector. So, we clarify what is the "surplus accruing to the capitalists" that is positive, but nevertheless no "exploitation" is possible. We show that if anyone is to be exploited, it is the producers of capital goods who are doomed in effect to self-exploitation inasmuch as all the output is distributed among the workers as their wage incomes. With no prior endowment of capital all the fruit of production in the capital goods sector must go to the workers under perfect competition either directly or indirectly. If directly, then the workers in the capital goods sector become the owners of the output. The owners of output can either consume it or offer (supply) it as capital to be used together with the remaining labor for the production of the final consumption goods. If they choose to consume it, then they choose not to become capitalists, not going roundabout in production. Only if it is worthwhile an effort, the working owners may choose to become capitalists.2 In a primitive Boem Bawerkian economy there exists no capital to begin with, however. The economy is endowed with nothing but labor. If labor alone is used to produce something, then the whole produce must be theirs provided that production is subjected to technological conditions of constant returns to scale and market conditions, if any, of perfect competition. If output is the workers’, then they may as well consume it directly, being their property. The whole product is theirs with no other factor inputs being used to produce it. But even if it is theirs, they need not consume it directly. They may save it for consumption later, if deferred consumption is expected to exceed direct consumption. If consumption is to be deferred, then output of labor can be used as an intermediate input. It may accordingly be considered as the workers’ property that the producers may 2 What if the workers choose not to become capitalists even if all the products are theirs to keep and even if going roundabout pays? They can let the producers behave as capitalists on behalf of them. However, the capitalist producers cannot rake in their rent on capital because it must be distributed to the workers in the capital goods sector as deferred wage payments anyway. But if wage rates in the two sectors get equalized in equilibrium, the workers in both sectors must get paid strictly higher than the average product of labor in the capital good sector. And who pays that extra? The capitalist producer does. Thus, the workers as the sole owners of labor endowment get everything, and the capitalist producers none. The latter’s economic profits disappear as they must under perfect competition. 3 utilize on behalf of the workers. The producers thus defined are accordingly in position to allocate both the intermediate capital (produced by primary labor alone) and the primary labor (remaining for employment at a later stage) to the production of final consumption goods. The producers' choice accordingly is between producing output directly with labor alone for final consumption and producing intermediate goods (called capital goods) first, followed by the second process of producing the final goods. In any case, all the fruit of production is the workers, nothing being left for the competitive producers. Here the producers may or may not be the capitalists as well. If the producers are not the capitalists, then it must be the primary stage workers who will be transformed to the capitalists in the second stage of production provided that they set aside their wage income to be used as an intermediate input. In any event, rent on capital, if any, is not the producers’ to keep. It is the workers’, or the worker capitalists’. The rent on capital that workers may own must be the workers’ to keep. Within the confines of such a simple model of production and distribution we also ponder and show whether or not the more capital-intensive method of production is tantamount to the more roundabout method of production. We will show in particular conditions under which the roundabout method of production requires its structure to be of more labor-intensive than capital-intensive, not the other way round. Greenhut and Ohta (1976, 1979) address impact of vertical integration of related industries or stages of production (physical distribution in effect) upon profits and welfare. Their strictly positive impacts (of lesser roundabout production in effect) are predicated, however, upon the assumption that unit costs of production/distribution are fixed, and independent from the number of intermediate stages of production/distribution. But if reducing the number of stages (or periods a la Boem Bawerk) of production raises the remaining sectors’ transactions costs large enough to cancel the benefits of ‘double marginalization’, then vertical integration may provide no rational grounds. It is such a supply side effect of either a more or a less roundabout method of production that the present article is concerned about. In what follows we set forth our simple model of production along with the underlying assumptions. Two sections 1and 2 of assumptions and the model are followed by the derivation in Section 3 of a critical set of technological parameters that tend to promote roundabout methods of production. Section 4 provides a formal proof that there exists a nonempty set of parameters that can help an apparently poor nation to surpass a strictly richer nation by going roundabout in production. 4 Section 5 concludes the paper. 1. Assumptions Assume that an economy is endowed with a given primitive factor of production, namely labor. The economy faces two alternative processes of production, one direct and the other indirect or roundabout method of production a la Boem Bawerk. The direct method of production requires labor input to catch fish, pick pecan, etc. or produce bundles of these and other necessary goods for direct consumption. Average labor productivity of such a composite product is assumed as given constant . The indirect method, by comparison, requires output of labor to be used as an intermediated input, called capital, which is combined with labor to produce the final consumption goods. The production technologies in either sector or stage of production, represented by production functions, are linear homogeneous. The consumption sector’s labor and capital inputs are further assumed as perfectly divisible and mutual complements as well as substitutes. For simplicity we further assume the production function in the final good sector is of the Cobb-Douglas type. 2. The Model Pursuant to those assumptions above our simple model of Austrian roundabout methods of production can be set forth as the following basic system of equations. 1) K = LK, KL 1 2) X = X 3) L = LX + LK The basic system of equations above is yet to be fully complete, however. It consists of only three equations in four endogenous variables: K, X, LK and LX, to be explained below. To begin equation 1) defines the production function for an intermediate output K, called capital, in terms of labor input LK allocated to the production of K, and a parameter to represent average product of labor. Given , equation 1) represents a linear homogeneous production function with respect to labor input LK alone. This will be referred to as the primary sector (or first stage) production function. Equation 2), by comparison, defines the production function for the final output X in terms of two inputs K and LX. Note here that K is a capital good produced in the primary 5 sector and LX labor input allocated to the final consumption good X. Equation 3) requires a given labor endowment L to be allocated to the primary sector LK or the final consumption-good sector LX. Assumed here is that employment at either sector of production precludes employment at the other sector, the two sectors being separated consecutively in two stages such that the first stage production operates during the daytime, say, and the second stage during nighttime. Those who work daytime to produce capital goods are to be replaced by those who work after, say, 5 o’clock to produce final consumption goods using the intermediate goods produced by the daytime labor. Any producer/firm to employ workers in the intermediate capital-good sector must promise the same wage rates to be offered in the consumption good sector under the pressure of free competition. With such promise the producers must offer their intermediate output K as capital on behalf of the primary sector’s workers. The producers in the final consumption-good sector must employ both the capital available from the primary sector and the remaining labor, not used in the primary sector, to produce the final consumption goods. Their optimization problem is given by: 4) Max X K L1X subject to 1) and 3) Solving the optimization problem 4) above requires the following first-order condition: 4)’ K LX The system of equations above consists of four independent equations in four unknown variables, now readily solved as follows. K* = L LX* = (1 L LK* = L X* = ()(1 – )1 – L 6 L. Figure 1 below illustrates how all the four endogenous variables, K, LX, LK and X, are determined within the confines of the simple, yet intrinsically Austrian roundabout methods of production. 3 Table 1 correspondingly presents the reduced form solutions to the variables in terms of the key parameters and , given L normalized as L =1. K X(LX, K), K = LK max K= L = L K LX LK L Figure 1 Going Roundabout in Production only if X > max K L Table 1 Primary Factor Input, Intermediate Input and Final Output in Equilibrium Negishi (1989, 94) apparently considers this to be a ‘simplified’ representation of Boem Bawerkian model. K. Shibata (1959), by comparison, would consider such a model to be more intrinsically Austrian than Walrasian. According to Shibata the Walrasian model is predicated on multiple primary factors of production as well as multi-final products whereas the Austrian model starts with labor alone as the sole primary factor of production, with which the primary sector production is to be carried out. Thus, nothing can be produced without an initial input of labor, not even capital goods that may be subsequently used along with labor to produce at a later stage in an intrinsically Austrian structure of production. For purposes of the present paper, however, changing the structure of production to the one that is more general Walrasian than simple Austrian does not change the basic results of the paper, so we apply an Occam’s razor to simplify our analysis. 3 7 First Stage Primary Factor Input LK Second (Final) Stage LX* = 1 Intermediate Output/Input K* = (as Output) K* = (as Input) Final Output None X*=()(1a)1a Underlying Parameters Note from Table 1 that the capital-labor ratio k* in the second stage (final consumption-good sector), defined as k* = K*/LX* = /(1 – ), increases with , given . 3. The Parameters Set ( , Enables Roundabout Methods to Pay Given the Cobb-Douglas type production technology as of 2), it is now straightforward to derive the conditions under which roundabout methods of production become superior, i.e., X* > LNote the feasibility condition is defined as follows. 5) X* K * L *1X Also note that substituting equilibrium values of K and LK from Table 1 into the left-hand-side of 5) yields 5)’ (also shown in the table): 5)’ X*=()(1a)1a Combining this with 5) in turn yields the following set SR of parameters and : 6) SR {(,; ) | /(1 ) (1 )} 1/(1 ) This set defines technological parameters and that make roundabout methods ofproduction feasible. Note that this set relation shows that for any given within the assumed domain of 1 > > 0, the labor productivity in the capital good sector is required to be strictly less than (1), which can be shown to be a strictly downward sloping curve (function) of , given . This relation of to is illustrated by the shaded area of ( ) in Figure 2 below. The shaded area asserts that, for any given within the 8 assumed range of 1 > > 0, the output elasticity is required to be strictly less than a critical level given by the relation SR. Thus, for example, if labor productivity in the capital good sector is low, say, with small enough to approach zero, the maximum output elasticity of capital that makes roundabout methods of production feasible is required to be large enough to approach unity. In this case, the method of production in the final consumption good sector becomes highly capital intensive. Conversely, if the labor productivity in the primitive stage of intermediate production happens to be large enough, the maximum that is required to justify roundabout production becomes low enough, and the related method of production must be highly labor intensive. Figure 2 illustrates the feasibility set SR (shaded in pale green), assuming for simplicity = 1.4 The following observations on the set are in order. (; ) = (1) B B 1/4 A 1/2 1 Figure 2. Country A’s (, ) ‘In’ the Feasibility Set SR, Country B’s ‘Not In’ i) If direct output productivity of labor is high enough to exceed the vertical intercept value of the curve (; ) in Figure 2 above, then going roundabout becomes infeasible regardless of .5 If a country has a high thanks to, say, If is treated as a parametric variable instead of a given constant, then the set SR above 1/(1 ) /(1 ) may be redefined as SR {( ,; ) | (1 )} , where is now treated as a parametric constant. Akiba (2004) assumes = 1/2 to derive the set SR as < 2/4. 5 What if labor productivity is less than unity, but high enough to approach unity? Going roundabout does become feasible even in such a case if only output elasticity of labor in the final sector is high enough so that the method of production becomes sufficiently more 4 9 rich natural resources, then there is no need to go roundabout in production. ii) If going roundabout pays, then direct output productivity of labor is required to stay below or unity when = 1.6 However, a low does not necessarily call for roundabout methods,. Unless is also low enough, going roundabout is likely to fail.7 Consider, for example, two countries with an identical , say, = 1/4, but suppose Country A’s = A is lower than 1/2 and B’s = B, by comparison, is higher than 1/2. Then Country A’s parameter combination (A <1/2, A=1/4) must be included in the shaded area of Figure 2, but B’s counterpart (B>1/2, B = 1/4) is not. This implies that A will go roundabout, but B will not. A related observation, which is straightforward and also intriguing, is that A will produce more X by going roundabout than B will. Not going roundabout, B will end up in producing no more than L, i.e., XA > XB = L; or strictly less if they choose to go roundabout. iii) More generally, for any given , the lower the output elasticity of capital in the final consumption good sector, the more labor intensive the roundabout process of production, and the higher the final output will be provided that (, ) is included in the set SR.8 iv) To be more precise as well as general (as a corollary in effect to footnote 8), it can be shown, for any given , that final output X* under conditions of roundabout methods of production becomes a strictly U-shaped convex function of . Given an output elasticity of labor that is either smaller or greater than a labor intensive than capital intensive. 6 However, even if direct labor productivity is very low, if output elasticity of labor is also low enough, then going roundabout may not pay. For roundabout methods to prove feasible under low enough , marginal product of labor in the second (final) stage of production must be high enough relative to marginal product of capital. 7 For an intuitive interpretation of this relation consider the following. Given low labor productivity in the primary sector, if the labor productivity in the second (or final) stage is also low relative to the productivity of capital, then the second stage production would require large enough input of high-powered capital. But in order to produce the needed capital a large input of labor in the primary sector is needed with little labor left for input to be combined to produce the final consumption goods. A large input of labor to produce miniscule capital to be combined with all the more negligible input of labor is most likely to yield unimpressive final outcomes. 8 For confirmation of this last result take partial of the left-hand-side of 5)’ with respect to . The result, being X*ln /(1), is strictly negative as long as < 1/(1+). 10 critical level of = 1/(1+), it then follows that the greater the deviation thereof, the greater the factor intensity of either input, i.e., capital or labor, will be and the greater the final output tends to be. (See Appendix Figure.) v) Getting back to the question of how a poor country A can surpass a rich country B via roundabout methods of production, note for any given B < for Country B there always exists A for Country A that is small enough to make roundabout methods of production superior to B’s direct counterpart methods.9 Put more generally, for any given B < , there exists a non-empty set of parameter combinations (A, A) that yields an outcome of XA(A, A) > B. 4. Proof of v): Consider an arbitrary B = < 1. Then for a roundabout output for County A to exceed this output level assumed for Country B the following inequality relation must hold. 7) (A ) (1 )1 B 0 A 1/0 1 (1 )( 1)/ This combined with 6) provides a set {, } that enables roundabout methods of production both feasible and strictly more productive than the counterpart direct methods with any B not greater than 1/(1).10 Figure 3 below obtained by superimposing 6) over Figure 2 above, illustrates how the poor Country A’s primary labor productivity can be compared to B’s (assumed to be as large as B =1/2 for simplicity) under which the poor A nevertheless can surpass the rich B in final output per capita. In the Figure a circular area A is a subset of (, ) in blue and stays strictly below the dotted line with = 1/2. This implies that Country A is endowed with strictly lower (A, A) than Country B’s counterpart (B, B), i.e., both A < B and A < B, which in turn implies that A’s finaloutput exceeds B’s. 7) with B = 1/2 9 It goes without saying, however, that even if Country A chooses a roundabout method, and its production methods become more labor intensive, it does not guarantee its final output and welfare to exceed B’s under the direct methods. Suppose A’s is strictly lower than B’s, i.e., A < B. Then, it is possible that even if A goes roundabout, its final output remain below B’s if A remains not small enough. 10 This critical value of 1/(1) becomes unity when = 1, as assumed in Figures 2 and 3. 11 1 B 1/2 A B = 1/2 6) 1/2 1 Figure 3. The Set {, } that Helps the Poor A Surpass the Rich B with B =1/2 Table 2 summarily presents certain particular combinations of technological parameters and that may yield contrasting impacts upon factor intensities and final outputs (per capita). Even if the poor A’s primary stage labor productivity is half B’s or even much lower, their final output per capita can be strictly higher than the rich B’s provided that the poor’s output elasticity of capital is low enough to induce its second (or final) stage of production highly labor intensive. Table 2. Impacts of Low cum Low upon Capital Intensity k and Final Output X/L k X/L Country A Low Low Low High Country B High High High Low Observations on the set SR yield more general propositions as follows. First, it is not necessarily the more capital-intensive methods of production that underscore the Austrian roundabout structure of production. Technological conditions exist under which the more labor-intensive, rather than capital-intensive, method of production proves to be an optimal roundabout structure of production. Second, of the set of parameters that promote roundabout methods of production, a 12 substantially large part (more than double the other parameters set 11 ) requires more labor-intensive than capital-intensive methods to be adopted. Third, for roundabout methods of production to prove feasible the primary sector’s labor productivity is required to be small enough. Otherwise, if labor productivity of something happens to be high enough to exceed unity, the producer can forgo any such roundabout production process as producing something first as a means of production, then combining it with labor input to produce something else for final consumption, or for further input. Forth, if labor productivity happens to be quite high, approaching but not exceeding unity, roundabout production can nevertheless be feasible, if only output elasticity of labor in the final consumption good sector is high enough so that the method of production becomes increasingly more labor-intensive than capital-intensive. Conversely, the lower the , the higher the maximum output elasticity of the good used as capital input so that the roundabout method of production can be more capital intensive than labor intensive. 5. Conclusion If economic development requires roundabout methods of production, it does not ipso facto require capital-intensive methods of production.12 On the contrary the more labor-intensive rather than capital-intensive methods could yield greater final output when the primitive labor productivity, denoted by , is low enough. If, on the contrary, were large enough, say exceeding unity in our simplistic model, then a large enough output elasticity of capital, Note from Figure 2 that the set {(,) | being a subset of the shaded set SR, assures roundabout methods to pay off, and moreover shows that the lesser the output elasticity of capital , the more labor-intensive the roundabout process of production becomes, and the larger the final output will be. This rectangular area is strictly greater than, more than double, the shaded area to the left of = 1/2 on the horizontal axis. The shaded parameters set on the right-hand side of = 1/2, by contrast, shows that greater than 1/2 and the related production process with relatively more capital intensive than labor intensive methods assure roundabout methods to be feasible. But it does not guarantee the greater and the related capital-intensive methods to yield the greater final output. 12 Hong Kong may be an example of success stories of economic growth with 11 labor-intensive methods of production in stark contrast with India with a bitter experience of development in heavily capital-intensive industries. See Mark Skousen (2002). 13 denoted by , could generate the greater final output than does the low enough . But the roundabout methods are strictly inferior to the direct method when primary/primitive labor productivity is high enough relative to the total factor productivity in the final sector, i.e., > 1/(1 – ). (Cf. footnote 10 supra.) Thus, whenever the roundabout methods are feasible, within the confines of our intrinsically Austrian structures of production with the primary factor of production being primitive labor alone, the more labor-intensive methods are generally superior to the more capital-intensive methods. If, however, happened to be large enough so that no labor-intensive method becomes feasible, then roundabout production itself should be abandoned. The poor (or weak) can surpass the rich (or strong) by going roundabout in production with more labor-intensive rather than capital-intensive methods. This is not to say, however, that the poor is ipso facto advantaged over the rich. If the rich has got the same output elasticity of capital as the poor does, the rich must be better off than the poor. For the poor (in primary productivity) to be able to surpass the rich, its output elasticity of capital is required to be strictly less, less enough than the rich’s. Indeed the poor’s chances to be able to surpass the rich increase with output elasticity of labor. That is, the smaller the , i.e., the larger the (1), the greater the final output for any given , average productivity of labor at the primary/primitive stage of production, will be. For any given , however, if is not small enough, then going roundabout in production tends to be hardly attractive. This is the case even if a higher could generate a greater final output by adopting a more capital-intensive than labor-intensive method of production. More generally put, if any combination of (, ) is not included in the set SR, Figure 2, then no country could benefit from going roundabout in production. Country B with a higher loses to Country A with a strictly lower because while B cannot take advantage of going roundabout in production A can, and can enjoy strictly greater final output than does B. The upshot: Happy are the poor provided that output elasticity of labor in the higher stage(s) of production is large enough to justify large input of labor, albeit combined with a small amount of capital. Even though the available capital is limited due to low primary productivity of labor besides the low output elasticity of capital as labor’s own output, it nevertheless is an indispensable factor along with labor in the production of the final output insofar as both factors are mutual complements as well as substitutes as 14 intrinsically embodied in the Cobb-Douglass production function we assume.13 A byproduct of our present inquiry, albeit straightforward, may warrant mention as a final note. Regardless of either more capital-intensive or labor-intensive structures of production that may yield surplus beyond average products of labor any such surplus will be distributed not to the capitalist producers, but instead to the workers alone. This follows from our basic assumptions that labor is the sole primary factor of production and perfect competition prevails in all the markets, labor as well as the product markets. 13 If the Cobb-Douglass production function is a warp of the present model, then an intrinsically Austrian roundabout structure of production starting with labor alone as the sole primary factor of production is a woof to weave our tale of the happy poor. 15 References Katsuhiko Akiba (2004), “On the Superiority of Labor-Intensive (rather than Capital-Intensive) Roundabout Methods of Production,” Ph.

However, in this case capital-intensive roundabout methods prove to be superior to the labor-intensive counterpart methods regardless of provided that > 1/, however. Without this proviso even capital-intensive roundabout methods become inferior to direct methods since lim X*(=1) = 1(maximum possible output under roundabout methods of production) not exceeding unity, falls below assumed as > 1. A final note on what > 1 means may be warranted. This condition being equivalent to K > L implies that the real value of an intermediate capital good produced by labor is greater than unity in labor units. Put alternatively, output of labor is more valuable than labor. Then the more capital intensive than labor intensive methods must make sense. Moreover, the higher the output elasticity of capital, the higher the capital intensity, and the greater the final output. 18
