Gesammelte Schriften 2 Kleinere Abhandlungen

[Front Matter and Editor's Introduction]: This introductory section provides the publication history and editorial context for the second volume of Böhm-Bawerk's collected works. Editor Franz X. Weiss discusses the enduring relevance of Böhm-Bawerk's interest theory, contrasting it with the views of contemporaries like Wieser. The introduction outlines the volume's structure, which includes defenses of the 'Positive Theory of Capital', polemics against critics like Clark and Walker, and critical evaluations of the interest theories of Marx, Clark, and Schumpeter. Key themes include the distinction between interest as an economic versus historical category and the importance of time in production. [Table of Contents]: A detailed table of contents for the volume, listing three main sections: fundamentals of capital and interest, defenses and supplements to the 'Positive Theory', and critical essays on other theorists. [The Concept of Capital]: Böhm-Bawerk defines capital, distinguishing between 'acquisitive capital' (private capital used for income) and 'productive capital' (social capital consisting of produced means of production). He clarifies that capital excludes land and labor, focusing on products used for further production or income. He warns against the common confusion between capital as a factor of production and capital as a source of rent, noting that the latter involves legal and social structures like private property. [History and Variations of the Capital Concept]: This section traces the dogmatic history of the term 'capital' through three periods: its expansion from money to goods, the distinction of productive capital by Adam Smith, and the modern separation of economic and legal-historical categories. Böhm-Bawerk reviews various competing definitions of capital from major economists including Marx, Jevons, Walras, Fisher, Clark, and Menger, highlighting the lack of consensus on whether to include land, labor, or value-funds. [Components and Types of Capital]: Böhm-Bawerk details the physical components of capital, such as raw materials, tools, machinery, and buildings. He explains the distinction between fixed (standing) capital and circulating (circulating) capital based on whether the good is consumed in a single production act or used repeatedly over time, affecting how costs are accounted for via amortization. [The Function of Capital in Production]: Böhm-Bawerk argues that capital is not an original factor of production but a result of labor and nature. Its primary function is to enable 'roundabout' (indirect) production methods, which are more technically productive but require more time. He defines capital goods as 'intermediate products' or 'ripening' consumption goods. The necessity of a subsistence fund (capital stock) to support workers during the time-lag of roundabout production is established as a core economic requirement. [Formation and Increase of Capital]: The author addresses the debate on whether capital is 'saved' or 'produced,' concluding that both are necessary. While physical capital goods must be produced, the ability to engage in time-consuming production requires prior saving—restricting immediate consumption to create a subsistence fund that covers the interval until the new production process yields results. [Capitalism and Economic Organization]: Böhm-Bawerk discusses 'capitalism' as a mode of production led by private owners of capital. He acknowledges socialist critiques regarding the 'planlessness' of private enterprise and the potential for crises, but highlights the advantages of private interest in driving capital formation. He concludes that while a non-capitalist order is conceptually possible, its practical superiority remains unproven, and the choice of organization is a broader social question beyond the scope of capital theory. [Zins: Begriff und Arten]: Böhm-Bawerk defines interest as the compensation for the temporary use of a good. He distinguishes between land rent (Grundrente) and capital interest (Kapitalzins), and further differentiates between gross interest (Rohzins) and net interest (reiner Kapitalzins) by accounting for depreciation, risk premiums, and administrative costs. He explains how the prevailing market interest rate serves as a benchmark for separating pure capital returns from entrepreneurial profit. [Der Ursprung des Kapitalzinses: Historischer Überblick]: A historical survey of theories regarding the origin of interest. It traces the evolution from ancient and medieval prohibitions (Aristotle, Aquinas) based on the 'sterility of money' to modern justifications. The text highlights how the rise of industrialism and the labor theory of value (Smith, Ricardo) led to a conflict between capital and labor, prompting socialist critiques of interest as exploitation and necessitating a formal scientific explanation of the 'surplus value' generated by capital. [Klassifikation der Zinstheorien: Produktivität, Nutzung, Abstinenz und Arbeit]: Böhm-Bawerk categorizes the first four major groups of interest theories. 1) Productivity theories (Say, Roscher, Wieser) claim capital produces interest through physical output, though they often fail to explain value surplus. 2) Use theories (Hermann, Menger) treat the 'use' of capital as a separate valuable entity. 3) Abstinence/Waiting theories (Senior, Marshall) view interest as compensation for the sacrifice of immediate consumption. 4) Labor theories (James Mill, Schäffle) view interest as a form of wage for the capitalist's past or intellectual labor. [Die Ausbeutungstheorie und die Zeitpräferenztheorie]: This segment contrasts the socialist Exploitation Theory (Marx, Rodbertus) with Böhm-Bawerk's own Time Preference (Agio) Theory. He critiques Marx for ignoring market price realities and the time-intensive nature of production. Böhm-Bawerk argues that interest arises because humans naturally value present goods more than future goods due to psychological factors and the technical superiority of 'roundabout' (time-consuming) production methods. He explains how this value difference manifests in loans, rentals, and entrepreneurial profit as goods 'ripen' into maturity. [Die Höhe des Kapitalzinses: Bestimmungsgründe und Marktdynamik]: An analysis of the factors determining the interest rate level. Böhm-Bawerk explains that the rate depends on the ratio between available capital (supply) and the demand for it (productive and unproductive). He introduces the law of the 'marginal' application of capital, citing Thünen, where the least productive but still necessary use of capital determines the general interest rate. He also discusses the historical downward trend of interest rates in developing economies and the role of international capital flows in leveling rates. [Zinsfußvariationen und der Einfluss der Geldmenge]: Böhm-Bawerk examines why interest rates vary across sectors (e.g., mortgage vs. discount rates) and clarifies the relationship between money supply and interest. He argues that while 'money abundance' can temporarily lower rates, long-term rates are determined by real capital abundance. Permanent increases in money supply eventually lead to currency devaluation (inflation), which absorbs the initial excess supply and returns the interest rate to its natural level based on real capital. [Literaturverzeichnis zum Zinsartikel]: A comprehensive bibliography of late 19th and early 20th-century economic literature regarding capital and interest, including works by Marx, Clark, Marshall, Fisher, Wicksell, and Menger. [Kritik an J. B. Clark: Kapitalgüter vs. Wahres Kapital]: Böhm-Bawerk begins a series of rebuttals to his critics, starting with Professor J. B. Clark. He disputes Clark's distinction between 'concrete capital goods' and 'true capital' (a permanent fund). Clark argues that capital 'synchronizes' labor and its fruit, effectively eliminating the production period. Böhm-Bawerk counters that this is a mystical abstraction; in reality, only concrete goods allow for production, and the time-lag between labor and consumption remains a fundamental technical reality that cannot be conceptualized away. [Einleitung zur Replik gegen General Walker]: Böhm-Bawerk introduces his response to the criticisms leveled against his work by General Francis Amasa Walker. He identifies four main points of contention that he intends to address in his defense. [Defense Against General Walker's Critique: Methodology and Historical Interpretation]: Böhm-Bawerk responds to General Walker's accusation of being ungenerous in his critique of past economists. He defends his classification of various thinkers, arguing that Walker's attempt to subsume all theories (Abstinence, Use, etc.) under a single 'productivity' umbrella misrepresents the distinct theoretical contributions of authors like Senior and Menger. He specifically addresses the case of Lord Lauderdale, correcting Walker's misunderstanding of how Lauderdale was categorized in his previous work. [The Status of Capital as a Secondary Factor of Production]: The author defends his classification of capital as a 'derived' or secondary factor of production against Walker's objections. Böhm-Bawerk argues that while humans and animals are part of nature physically, in economic theory, the human agent is the central subject, justifying the distinction between original factors (labor and nature) and the produced means of production (capital). He maintains that understanding the origin of capital is relevant to the theory of interest. [The Three Causes of Interest and the Productivity Fallacy]: Böhm-Bawerk clarifies his interest theory, correcting Walker's claim that he relies solely on psychological 'underestimation' of the future. He explains the three pillars of his theory: differences in provision (need), the technical superiority of present goods (productivity of roundabout methods), and psychological time preference. He critiques the 'productivity theory' for failing to explain why competition doesn't eliminate the surplus value (interest) by equalizing the price of machines with their output value. [Competition, Scarcity, and the Final Rebuttal to Walker]: The final section of the critique addresses Walker's circular reasoning regarding machine prices and interest. Böhm-Bawerk argues that simply citing 'scarcity' and 'productivity' provides the framework but not the mechanism of interest. He concludes that the fundamental difference lies in his focus on the value difference between present and future goods, whereas Walker's focus on 'production over time' fails to account for non-productive interest (e.g., consumer loans). [Kritik an General Walkers Auffassung der Wertentstehung]: Böhm-Bawerk responds to General Walker's critique regarding the origin of value. He clarifies that while production is a cause of value, it is not the sole cause, emphasizing the interplay between supply (Deckung) and demand (Bedarf). He defends his position against 'naive' productivists who claim capital has an inherent value-creating power, arguing instead that value is derived from future utility rather than past production costs. [Die Ansichten von Mr. White: Unternehmergewinn vs. Kapitalzins]: The author critiques Horace White's theory that interest stems from the intelligence of 'captains of industry'. Böhm-Bawerk argues that White confuses entrepreneurial profit (based on personal talent) with normal interest (an objective return on capital). He uses the analogy of ground rent to show that while skill can increase returns, there is an underlying objective cause for the normal rate of interest independent of the individual's 'smartness'. [Auseinandersetzung mit Hugo Bilgram: Kosten und Zeitpräferenz]: Böhm-Bawerk addresses Hugo Bilgram's focus on production costs and his rejection of the time-preference theory. He refutes Bilgram's claim that the Austrian school ignores costs, pointing to his own work on the 'ultimate standard of value'. He also defends his thesis that present goods are generally valued higher than future goods, explaining that the demand for present goods on the subsistence market (primarily from laborers selling their 'unripe' labor) far outweighs the supply from savers. [Terminologie und Kostenbegriffe bei Bilgram und Hawley]: A discussion on economic terminology, specifically the distinction between 'present/future goods' and Bilgram's suggested 'mature/immature goods'. Böhm-Bawerk acknowledges the potential for linguistic confusion in English translations. He also notes the conflicting critiques of Bilgram and Hawley regarding the definition of costs, defending a multi-faceted approach to the concept of cost depending on the scientific task at hand. [Diskussion mit Professor Macvane: Abnehmende Mehrerträge und Produktionsperioden]: Böhm-Bawerk engages with Professor Macvane's skepticism regarding the law of diminishing returns from lengthening production periods. He argues that while longer detours are more productive, the marginal gain decreases. He clarifies that this law applies to existing methods, not just new inventions. Furthermore, he demonstrates how the level of wages determines the choice of production method: higher wages incentivize more capital-intensive (longer) production processes. [Subjektiver Wert künftiger Güter und Kritik an F. B. Hawley]: The author defends the psychological reality of valuing future goods against Macvane's charge of 'fantastic' language. He then addresses Frederick B. Hawley's critique, suggesting Hawley had not fully read the 'Positive Theory'. He refutes Hawley's claim that he confuses pure interest with risk premiums or entrepreneurial wages, pointing to specific passages where he explicitly distinguishes these components. [Der Ursprung des Kapitalzinses: Replik an J. B. Clark]: Böhm-Bawerk begins a rebuttal to J. B. Clark's theory of 'permanent capital' and 'specific productivity'. He asserts that his own theory regarding the higher value of present goods over future goods was always intended to apply to money as well as other goods, countering Clark's suggestion that money was a late addition to the problem's scope. [Critique of Clark's Misinterpretation of the Interest Theory as Abstinence]: Böhm-Bawerk refutes J.B. Clark's characterization of his interest theory as a form of 'abstinence theory'. He clarifies that interest is not a reward for personal suffering or 'waiting' in a psychological sense, but rather an objective result of the higher value of present goods over future goods in time-consuming production processes. [The Calculation of Production Periods: Absolute vs. Average]: The author addresses Clark's objection regarding the impossibility of extending production periods. He distinguishes between the 'absolute production period' (stretching back to civilization's start) and the 'average production period' (the mean time between labor input and consumption), arguing that only the latter is relevant for capital theory and is indeed extendable. [Technical Productivity vs. Economic Profitability]: Böhm-Bawerk analyzes Clark's example of water and steam mills to distinguish between technical productivity (output per unit of labor) and economic productivity (interest on capital). He demonstrates that for a longer production process to be equally profitable, it must possess higher technical productivity to compensate for the longer interest-bearing period. [Some Disputed Questions of Capital Theory (1899) - Preface]: A preface to a collection of three essays from 1899. The author explains his intent to clarify specific 'virgin' questions in capital theory that have caused misunderstanding, rather than presenting a new theory. He emphasizes the need for theoretical depth to resolve polemical disputes in the field. [The Rule of Greater Productivity of Longer Roundabout Methods]: Böhm-Bawerk defends his fundamental thesis that longer production processes are generally more productive. He responds to skeptics like Lexis and Philippovich by defining the 'average waiting time' and linking it to the widely accepted notion of capital productivity. He argues that higher capital per worker is essentially synonymous with a longer average production period. [Refuting Lexis: Technical Progress and the Length of Production]: The author critiques Lexis's argument that technical progress shortens production periods. Böhm-Bawerk identifies a confusion between 'working time' (labor hours) and the 'production period' (time between investment and consumption). He uses examples like railways and sewing machines to show that while the final act of production is faster, the total preparatory process is actually longer and more capital-intensive. [The Coexistence of Lengthening and Shortening Inventions]: Böhm-Bawerk explains the relationship between inventions that lengthen production (requiring more capital) and those that shorten it. He argues that while shortening inventions exist, they are quickly exhausted because they don't require new capital. Conversely, the pool of potential lengthening improvements is inexhaustible and limited only by the available capital stock and the prevailing interest rate. [The Scope of the Productivity Rule and Theoretical Methodology]: The author clarifies that his theory does not require the rule of greater productivity for longer periods to be universal. It only requires that there are enough such opportunities to exceed the available capital supply. He uses an analogy with exchange rates to show how marginal demand determines the 'agio' (interest) regardless of the majority of cases. [The Production Process as a Unified Whole and the Problem of Unknown Magnitudes]: Böhm-Bawerk defends the methodology of treating the production process as a unified whole despite the division of labor. He addresses Lexis's skepticism regarding the 'unknown' nature of production periods, arguing that precise numerical measurement is unnecessary to establish the qualitative empirical rule that longer processes yield higher returns. [Lexis' Critique of the Relationship Between Profit Rates and Production Periods]: Böhm-Bawerk outlines Wilhelm Lexis's critique of his interest theory. Lexis argues that the interest rate is determined by the profitability of individual business stages rather than the total production period of a good. He contends that entrepreneurs only care about their specific business cycle and not the overarching production process. [Mathematical Calculation of Average Waiting Time]: A brief mathematical interlude calculating the average waiting time for labor units in a multi-stage production process, resulting in an average of one year. [The Reconciliation of Total Profitability and Partial Profitability]: Böhm-Bawerk responds to Lexis by arguing that the apparent conflict between the profitability of the whole process and its parts disappears at the margin of 'the last permitted production extension'. He uses an analogy of supply and demand versus production costs to show that while individual entrepreneurs look at their specific profit rates, these rates are fundamentally tied to the productivity gains of the entire process through the tendency of profit rates to level across the economy. [Numerical Proof of Interest Rate Determination]: Böhm-Bawerk provides a detailed numerical example to prove that the interest rate, determined by the marginal productivity of the last production extension, aligns with the average surplus of the entire process. He demonstrates that a 10% interest rate on the marginal capital investment corresponds to the increase in average annual labor product when the production period is extended from six to seven years. [The Logic of Production Extensions and Profit Leveling]: Böhm-Bawerk continues his proof, explaining that the marginal extension of production must yield the normal interest rate. He argues that the law of interest must be derived from the tendency toward profit leveling (Nivellierung), similar to how market price laws assume free competition rather than monopolies. [The Organic Unity of the Production Process]: Böhm-Bawerk argues that the division of the production process into independent businesses is a secondary phenomenon that does not change the underlying laws of interest. He explains that while individual entrepreneurs act out of self-interest, the market mechanism (specifically profit leveling) ensures that their actions mirror the productivity of the entire unified process. He addresses the 'methodological dispute' by asserting that theory must assume the tendency toward profit leveling to explain a 'ruling interest rate'. [Interdependent Influences Between Production Stages]: The author challenges Lexis's claim that there is no 'overarching influence' between production stages. He demonstrates that because all stages derive their compensation from the final product's value, the costs and profit requirements of one stage (e.g., raw material production) directly impact the viability and profitability of subsequent stages (e.g., manufacturing). [The Invisible Hand in Capitalist Production]: Böhm-Bawerk describes how the pursuit of individual profit leads to a socially harmonious outcome without central planning. He uses the example of sewing machines to show how technical improvements in one stage are weighed against costs in another. The market automatically excludes production extensions that are not sufficiently profitable for the whole process, aligning individual actions with the overarching economic logic of interest and productivity. [The Measurability of Economic Forces and Theory Validity]: The author addresses the skeptical impression that a theory is useless if its variables (like total production periods or subjective utility) cannot be exactly measured. He argues that many real forces (like lightning or human passion) are unmeasurable yet undeniably causal. Economic theory explains the *nature* of these forces and how they interact, even if practitioners and theorists lack precise numerical data for every specific case. [Unconscious Economic Action and the Cost Law]: Böhm-Bawerk explains that economic actors do not need to know the 'total production period' for the theory to be valid; they simply follow profit signals. He compares this to the 'Law of Costs', where prices align with total social labor and abstinence even though no one can measure the exact sum of these inputs. Theory identifies the general laws of how these unknown quantities interact to produce stable market outcomes like the 'normal interest rate'. [The Scope and Postulates of Interest Theory]: Böhm-Bawerk begins a new section examining what a correct interest theory must achieve. He criticizes Wilhelm Philippovich for failing to distinguish between 'pure' capital interest and entrepreneurial profit. He argues that interest theory should only explain the return on capital itself, not the mixed income resulting from personal entrepreneurial qualities or risk premiums. [Critique of Eklektizismus: Dietzel's Multi-Theory Approach]: The author critiques Heinrich Dietzel's suggestion that different cases of interest (e.g., consumer loans vs. business capital) should be explained by different theories (exploitation, productivity, or use theory). Böhm-Bawerk argues that this 'eclecticism' is logically inconsistent because the premises of these theories contradict each other. A valid theory must provide a unified explanation for the entire phenomenon of interest. [Interest in Non-Extended Production and Commercial Capital]: Böhm-Bawerk defends his theory against Philippovich's claim that it cannot explain interest in commercial capital or cases where technical changes increase yield without extending the production period. He argues that as long as a time difference exists between investment and return, the social 'agio' (premium) for present goods will produce interest, regardless of whether a specific production stage was lengthened. [The 'Vulgar-Economic' Offshoot of Exploitation Theory]: Böhm-Bawerk analyzes Wilhelm Lexis's view that interest arises from the economic power imbalance between capital and labor. He labels this a 'vulgar-economic' version of Marx's exploitation theory. While Lexis avoids Marx's labor theory of value, he still attributes interest to the worker's necessity to sell labor for present goods, a view Böhm-Bawerk finds logically incomplete as it fails to explain why competition among capitalists doesn't eliminate this surplus. [The Role of Competition and the 'Social Fashion' of Anti-Capitalism]: The author argues that 'economic power' alone cannot explain normal interest because competition among entrepreneurs would drive prices down and wages up until the surplus disappears, unless a deeper cause (like the time-valuation of goods) exists. He critiques the modern 'anti-capitalist fashion' in economic theory, where scholars adopt parts of socialist doctrine without rigorous proof, and calls for a return to dispassionate, causal scientific inquiry. [The Function of Saving and Capital Formation]: Böhm-Bawerk responds to Mr. Bostedo's critique of the role of saving. He clarifies that saving is not merely a negative 'non-consumption' but a positive impulse that redirects production from immediate consumer goods to 'intermediate' capital goods. He refutes the idea that saving reduces total production, arguing instead that it shifts the *time* and *type* of goods produced to meet future needs. [Karl Marx and the Riddle of the Average Profit Rate]: Böhm-Bawerk begins his famous critique of the third volume of Marx's 'Capital'. He highlights the central contradiction: Marx's first volume claims value is based on labor, yet profit rates in reality level out across industries regardless of labor intensity. He discusses the long-awaited 'solution' promised by Marx and the 'prize riddle' literature that emerged among economists waiting for the third volume's publication. [Marx's Value and Surplus Value Theory (Volume I)]: A summary of the foundational theories in Marx's Volume I. Marx identifies labor as the 'common substance' of value. He distinguishes between constant capital (means of production) and variable capital (wages), asserting that only the latter produces surplus value through the exploitation of labor power beyond the 'necessary labor time'. [The Transformation of Values into Prices of Production (Volume III)]: Böhm-Bawerk explains Marx's 'solution' in Volume III. Marx admits that commodities do not sell at their labor values but at 'prices of production' (cost price plus average profit). This transformation occurs through competition and the migration of capital, which levels profit rates across industries with different 'organic compositions' of capital. Total profit equals total surplus value, but individual prices deviate from labor values. [The Irreconcilable Contradiction in Marx's System]: Böhm-Bawerk argues that Marx's Volume III flatly contradicts Volume I. The 'Law of Value' (exchange based on labor) is abandoned in favor of a cost-plus-average-profit theory. He cites Achille Loria and Werner Sombart to illustrate the widespread recognition of this 'theoretical bankruptcy'. He concludes by preparing to analyze Marx's own attempts to defend the continued relevance of the Law of Value. [Kritik des ersten Arguments: Die Summe der Preise und Werte]: Böhm-Bawerk examines Marx's first argument for the validity of the law of value: that while individual prices deviate from values, the sum of all prices equals the sum of all values. He critiques this as a tautological and meaningless defense, arguing that the purpose of a law of value is to explain relative exchange ratios between individual goods, not the aggregate sum of a national product. He also highlights Marx's logical error in confusing a statistical average of fluctuations with a permanent divergence between fundamentally unequal magnitudes. [Kritik des zweiten und dritten Arguments: Preisbewegung und historische Priorität]: The author critiques Marx's second argument (that labor time governs price movement) by noting that labor is only one factor among many, such as the duration of capital investment. He then addresses the third argument regarding the 'original' state where the law of value supposedly ruled directly. Böhm-Bawerk argues this historical priority is an unproven hypothesis that ignores the economic reality of time-preference and capital requirements, citing Werner Sombart to show that capitalism did not historically begin in sectors with high labor intensity as Marx's theory would suggest. [Kritik des vierten Arguments: Indirekte Regulierung der Produktionspreise]: Böhm-Bawerk analyzes Marx's fourth argument: that the law of value regulates production prices 'in the last instance' by determining total surplus value and the average profit rate. He deconstructs the production price into wage costs and average profit, demonstrating that changes in wage levels (independent of labor quantity) directly affect production prices, which contradicts the exclusive rule of the law of value. He concludes that the logical chain connecting aggregate value to individual production prices is broken because the concept of 'aggregate value' is economically hollow. [Critique of Marx's Value Theory: The Disconnect Between Value and Production Prices]: Böhm-Bawerk continues his critique of the third volume of Marx's Capital, focusing on the logical gaps in the transition from value to production prices. He argues that Marx's 'value law' becomes hollow when applied to the total value of commodities, as it fails to account for the influence of wage levels and the total social capital on the profit rate. The author demonstrates that the quantity of labor is only one of several factors determining production prices, alongside wage rates and capital mass, which Marx fails to integrate logically. [The Methodological Errors in Marx's Derivation of Value]: Böhm-Bawerk analyzes the origin of Marx's fundamental thesis that labor is the sole source of value. He critiques Marx's dialectical deduction, specifically the 'method of exclusion' used in the first volume of Capital. The author argues that Marx arbitrarily restricts his investigation to 'commodities' (products of labor) while ignoring natural resources that also possess exchange value, and that his abstraction from use-value is logically flawed because it could just as easily be used to abstract from labor itself. [Qualified Labor and the Tactical Abstractions in Marx's System]: This segment addresses Marx's treatment of qualified (skilled) labor and his tactical use of abstraction to maintain the labor theory of value. Böhm-Bawerk argues that Marx's reduction of skilled labor to 'multiplied simple labor' is a circular argument based on actual exchange rates rather than an independent measure. He also critiques Marx's decision to ignore the influence of capital investment and competition in the first two volumes of Capital, characterizing it as a methodological 'mortal sin' that hides the contradictions eventually revealed in Volume III. [Werner Sombart's Apology for Marx: A Critique]: Böhm-Bawerk responds to Werner Sombart's defense of Marx. Sombart suggests that Marx's 'value' is not an empirical fact but a 'mental fact' or a logical tool. Böhm-Bawerk rejects this interpretation, asserting that Marx intended his value law to be an objective, empirical law of reality. He also critiques Sombart's methodological distinction between 'objectivism' (Marx) and 'subjectivism' (Austrian School), arguing that regardless of the method chosen, Marx's specific execution and conclusions remain logically and empirically untenable. [Critique of J.B. Clark's Theory of Capital and Interest]: Böhm-Bawerk shifts his focus to the American economist J.B. Clark. He critiques Clark's distinction between 'capital goods' (concrete instruments) and 'true capital' (a permanent fund of value). Böhm-Bawerk argues that this distinction is a mystical abstraction that leads to a flawed 'productivity theory' of interest. He specifically attacks Clark's idea of 'synchronization,' which claims that capital eliminates the time interval between labor and its fruits, arguing instead that the time-consuming nature of production is an inescapable reality that Clark's theory merely masks through dialectical fictions. [Critique of Schumpeter's Dynamic Theory of Interest]: Böhm-Bawerk critiques Joseph Schumpeter's theory that interest is a purely 'dynamic' phenomenon that would not exist in a 'static' economy. Schumpeter argues that interest is a share of entrepreneurial profit arising from new combinations. Böhm-Bawerk counters that interest is a 'static' category present in all economic states due to the time-preference and the higher productivity of roundabout production processes. He argues that Schumpeter's reliance on credit and 'purchasing power' as the source of capital is a return to mercantilist errors and fails to account for the empirical reality of interest in non-developing sectors (like housing) and stable periods.
