Theorie der Volkswirtschaft 2. Teil Geld und Kapital

[Title Page and Table of Contents]: The front matter and comprehensive table of contents for Oskar Engländer's 'Theorie der Volkswirtschaft', Part 2: Money and Capital. It outlines the structure of the work, covering money as a medium of circulation, the nature of capital, single-stage and multi-stage production, and economic fluctuations. [Money as a Medium of Circulation: Cash Transactions and the Quantity Equation]: This section establishes the foundational monetary theory for a cash-based economy using money without intrinsic value. Engländer derives a complex quantity equation that incorporates cash reserves (R), the frequency of markets (f), and the relative frequency of different types of markets (n). He explains how the velocity of circulation is a composite of these factors and how they determine the total price sum and individual prices. [The Velocity of Money and Dynamic Price Adjustments]: Engländer analyzes the components of the velocity of money, distinguishing between real and 'unreal' reserves. He explores the dynamic effects of changes in the money supply, arguing that while a monetary increase leads to a proportional rise in the total price sum in a stationary state, the transition period involves complex shifts in relative prices and income distribution as the new money moves through the economy. [Monetary Expansion, Price Ratios, and Economic Tendencies]: A detailed examination of how new money enters the economy and affects price ratios. Engländer discusses how the impact depends on whether the increased demand targets goods with fixed quantities or cost-based goods. He concludes that while initial monetary shocks cause continuous price fluctuations, there is a tendency for the economy to return to previous price ratios over time as income levels stabilize. [Changes in Monetary Reserves and Market Frequency]: This section explores how changes in the velocity of money—specifically through changes in real reserves and market frequency—affect the total price sum. Engländer notes that increasing market frequency doesn't automatically increase the price sum because it often initially converts 'unreal' reserves into 'real' reserves, which may remain idle unless actively spent. [The Impact of Goods Quantities and Price Shocks on the Monetary Equation]: Engländer argues that changes in the quantity of goods do not directly affect the total price sum (which is determined by monetary factors) but instead alter price ratios and income distribution. He also dismisses the concept of 'velocity of circulation for goods' as being secondary to the velocity of money, and discusses how price expectations can independently trigger changes in the total price sum. [Liquid Money Demand and Marginal Utility of Money]: The author defines 'liquid money supply' and 'money demand' as technical requirements based on income and market frequency rather than subjective utility. He critiques the application of 'marginal utility' to money without intrinsic value, arguing that the declining marginal utility of money is a consequence of higher prices and expanded consumption, not a causal explanation for the value of money. [Credit, Deferment, and Clearing Systems]: This section introduces credit through deferred payments and clearing (Abrechnung). Engländer explains that while simple deferment might not change the price level, clearing systems (where mutual claims are offset) effectively increase the total price sum by allowing transactions to occur without physical cash, thus acting as a form of increased monetary velocity. [Money Lending and Banking Operations]: An analysis of money lending and the role of banks as intermediaries. Engländer distinguishes between lending from existing reserves (which increases velocity) and lending that displaces consumption. He introduces 'book credit' (Buchleihe) and explains how bank-mediated clearing and deposit transfers function within the monetary equation, including the role of bank reserves (RB) and liquidity ratios. [Central Banking and Banknotes]: The final section of the chunk discusses central banks and the nature of banknotes. Engländer classifies banknotes as a form of money due to their physical circulation and clearing function. He distinguishes them from metal money based on their origin in credit (lending against expected income) and notes that central banks have a unique lack of absolute economic constraint compared to private banks, allowing for potential over-issuance for state purposes. [Money with Intrinsic Value and its Effects on Price Formation]: Engländer examines how money with intrinsic value (Eigenwert) differs from money without it. He argues that while the subjective-social and objective-technical foundations of price formation remain the same, intrinsic value directly links price ratios to absolute prices. He analyzes how changes in the velocity of circulation and the use of credit affect the total price sum differently when money has intrinsic value, noting that the marginal utility of the monetary substance (like gold) does not necessarily decrease in exact proportion to its quantity increase. [The Impact of Production Costs and Free Mintage on Money Supply]: This section explores the economic consequences of money that has production costs and 'free mintage' (freie Ausprägung). Engländer describes a self-regulating mechanism where the production of money ceases if its production costs exceed its value as currency, and resumes when wear and tear or price drops make production profitable again. He concludes that while production costs and intrinsic value can influence the money supply, they do not fundamentally alter the underlying principles of price formation and the total price sum. [Theory of Consumer Interest (Konsumtivzins)]: Engländer analyzes the 'consumer interest' (Verbraucherzins), which arises from loans taken for immediate consumption rather than production. He defines the conditions under which a borrower is willing to pay interest, primarily based on the higher valuation of present goods over future goods due to expected changes in future income. He provides mathematical formulas and numerical examples to determine the upper limits of interest rates based on 'price willingness' (Preiswilligkeit) and the ranking of goods in a rational household's budget. [Market Dynamics and Distributional Effects of Consumer Loans]: This segment discusses how the actual market interest rate for consumer loans is formed through competition between lenders and borrowers. Engländer uses a tabular example to show how different levels of loan supply interact with varying degrees of price willingness. He also examines the long-term effects of consumer interest as a permanent institution, explaining how it shifts the distribution of liquid money within the economy and affects the total price sum by increasing the velocity of circulation. [Interest on Deferred Payments and the Truck System]: The final section of this chunk addresses interest in the context of deferred payments (Stundung) for consumer goods. Engländer explains that price differences between cash purchases and credit purchases function as interest, driven by the seller's ability to wait for payment. He distinguishes this from the 'Truck system,' where workers receive goods in lieu of wages, noting that price surcharges there are often due to dependency rather than pure interest. The chunk concludes by transitioning to the second major section of the work: Capital. [Origin and Level of Capital Interest in a Simple Economy]: Engländer begins an investigation into the origin and level of capital interest using a simplified model of a closed economy consisting only of capitalists and workers. He explains the economic cycle where capitalists use money capital to pay wages at the start of a period and receive the proceeds from selling the resulting products at the end. The interest rate is defined by the ratio of the capitalists' consumption expenditure to the total capital invested. He demonstrates through examples how the division of labor provides a productivity advantage that allows for both higher wages for workers and a surplus (interest) for capitalists compared to independent production. [The Relationship Between Capital Interest and Productivity Advantages]: This section explores why capital interest is not necessarily equal to the total productivity advantage gained through capital use. Engländer argues that the benefits of capital-intensive production are distributed between capitalists (as interest) and workers (as higher real wages). He critiques the idea of 'imputation' (Zurechnung), noting that while capital enables higher output, the resulting interest is a market phenomenon rather than a direct equivalent of the technical advantage. He concludes that the productivity gain acts as an upper limit for interest, but does not determine its specific level. [Limits and Determinants of the Interest Rate: Efficiency and Reserves]: Engländer identifies the specific boundaries of the interest rate. The upper limit is defined by the 'efficiency of capital' (the productivity ratio), because if interest were higher, workers would earn more by working independently for the market. He also adjusts his model to account for real and unreal reserves (Rücklagen) and variations in the timing of labor and consumer markets. He shows how these factors influence the required amount of liquid money and the effective interest rate on total versus liquid capital. [Psychological Determinants: Abstinence, Provision, and the Lower Limit of Interest]: The text delves into the psychological motivations for capital provision, distinguishing between 'abstinence without sacrifice' (simple provision for future consumption) and 'abstinence with sacrifice' (saving induced by interest). Engländer introduces the concepts of the 'inverse provision number' (Vorsorgezahl) and 'sacrifice number' (Opferzahl) to define the lower bounds of interest. Interest must be high enough to motivate capitalists to maintain their capital rather than consuming it. He explains how capital shifts from those with low future-orientation to those with high future-orientation until a stable interest rate is reached. [The Wage Struggle and the Functional Interdependence of Wages and Interest]: In the final section of this chunk, Engländer addresses the critique of the wage fund theory. He argues that while wages, capital, and interest are mutually dependent, the interest rate is ultimately constrained by psychological limits (provision and sacrifice numbers). Within these limits, the specific distribution between wages and interest is determined by the 'wage struggle' (Lohnkampf) between capitalists and workers. He provides a numerical example showing how the system moves toward equilibrium when interest rates fall outside these psychological boundaries. [Kapital verschiedener Wirksamkeit und die Seltenheitsrente]: Engländer examines the impact of varying capital effectiveness across different sectors. He introduces a scenario where only one industry is accessible to capital while others remain under independent production, leading to the conceptualization of capital interest as a scarcity rent (Seltenheitsrente) rather than a differential rent. The section explores how the wage level in non-capitalist sectors dictates the available labor supply for capitalist enterprises and how the resulting price ratios determine the interest rate. [Bedingungen für den beharrenden Zustand bei gemischter Erzeugung]: This segment discusses the conditions required for a stationary state (beharrender Zustand) in an economy with both capitalist and non-capitalist production. It emphasizes the distribution of liquid money between capital, the consumption funds of capitalists, and the funds of independent producers. Through numerical examples, the author demonstrates how shifts in wages and price sums lead to labor migration between sectors until a stable equilibrium is reached where no further tendency for wage changes exists. [Verhältnis von Kapitalzins und technischer Wirksamkeit]: Engländer analyzes the relationship between the technical efficiency of capital and the interest rate. He argues that while efficiency influences interest, they are not identical; in fact, due to market price dynamics (including the 'price-willingness paradox'), an increase in technical efficiency can sometimes lead to a lower interest rate. The text contrasts the stability of mixed production systems with the instability of systems where capitalist and non-capitalist methods produce the same good. [Kapitalallokation bei unterschiedlicher sektoraler Wirksamkeit]: The author explores how capital is distributed among various industries with different levels of efficiency. Capital will first flow to the most effective sectors until their interest rate drops to match the potential returns of less effective sectors. Engländer concludes that the interest rate is not simply determined by 'marginal efficiency' (Grenzwirksamkeit), but rather the interest rate (determined by capital/consumption ratios and labor struggles) dictates the limit of which industries can be profitably operated under a capitalist model. [Betriebsgröße und die Grenzen der Kapitalwirksamkeit]: This section examines varying capital effectiveness within a single enterprise, focusing on increasing and decreasing returns. Engländer defines the 'optimal enterprise size' as the point where the total effectiveness of capital is maximized, rather than where marginal effectiveness begins to decline. He notes that in industrial reality, factors like distribution costs and the reach of fixed costs (Reihenkosten) eventually limit growth, leading to a spatial distribution of optimal-sized plants across the economy. [Dynamic Phenomena: Effects of Labor Force Changes on Interest and Wages]: This section examines the effects of an increasing labor force on wages and capital interest. Engländer argues that in a purely capitalist system with a fixed money supply, an increase in workers leads to lower nominal wages but stable total capital returns, improving the real income of capitalists while maintaining the real income of individual workers due to falling prices. He also explores how shifts in demand between capitalist and non-capitalist sectors can alter the distribution of the social product. [Impact of Capital Effectiveness on Interest Rates]: The author analyzes how changes in the effectiveness of capital (productivity) influence interest rates across different economic scenarios. In a fully capitalized economy, increased effectiveness generally lowers prices without changing the interest rate, unless monetary factors or labor hours change. However, in partially capitalized economies, increased effectiveness in a specific sector can lead to capital migration and shifts in the general interest rate depending on the price elasticity of demand for those goods. [Psychological Factors: Provision and Sacrifice in Capital Accumulation]: Engländer discusses how psychological dispositions regarding future provision (Vorsorgezahl) and the sacrifice of consumption (Opferzahl) determine capital supply. A decrease in future provision leads to capital consumption and rising interest rates, while an increased drive to save (including 'chrematistics' or the irrational pursuit of wealth) increases capital and lowers interest rates. He explains how these psychological boundaries interact with the prevailing market interest rate to stabilize capital levels. [Monetary Changes and Social Distribution]: This segment explores the consequences of increasing the money supply. If capitalists add new money to their productive capital, wages rise and the interest rate falls; if they use it for consumption, prices rise and workers' real income falls. Engländer posits that individual capitalists typically split new funds between capital and consumption based on the current interest rate, which tends to neutralize long-term social shifts. He also considers the role of 'real' and 'unreal' cash reserves (Rücklagen) in modulating these effects. [Velocity of Circulation and the Mechanics of Saving]: The final section of the chunk examines how changes in the velocity of money circulation—driven by improvements in payment systems or changes in saving habits—affect the economy. Engländer argues that the transition to capitalist production or increased saving requires an increase in monetary velocity to prevent a drop in the total price sum of consumer goods. He provides numerical examples to show how the timing of saving (whether it starts in the labor market or the consumer market) affects price levels. [The Role of Entrepreneurial Profit and Credit in Capital Interest]: Engländer examines how entrepreneurial profit and interest are formed when credit and deferred payments are introduced into a capitalist economy. He argues that if workers deferred their wages until products were sold, capital interest would be eliminated, leaving only entrepreneurial profit; however, in practice, the entrepreneur acts as a middleman between capitalists and workers, with profit determined by price competition within limits set by alternative employment wages and risk premiums. [The Formation and Components of Entrepreneurial Profit]: This section analyzes the relationship between entrepreneurial profit, risk, and capital size. Engländer rejects the idea that profit is a simple sum of 'entrepreneurial wage' and 'risk premium,' viewing it instead as a unified income formed through competition; he also explains how the scale of an enterprise and the entrepreneur's ability influence the total profit relative to the capital employed. [Monetary Circulation and the Impact of Saving on Entrepreneurial Profit]: Engländer describes the velocity of money across different classes (capitalists, entrepreneurs, workers) and analyzes how increased capital through saving affects the economy. He notes that while saving generally increases nominal and real wages while lowering interest rates, it can lead to entrepreneurial losses and insolvency if workers increase their cash reserves (Genußrücklagen) instead of spending their higher wages on the consumer market. [The Effects of Money Supply Increases and Central Bank Credit]: The text explores the consequences of increasing the money supply and the specific role of central bank (Notenbank) loans. Engländer argues that central bank credit should only be granted for productive purposes to entrepreneurs; if used to lower interest rates below the natural threshold of 'capitalist foresight' (Grenzvorsorgezahl), it could theoretically eliminate private interest as an income category by replacing private capital with central bank notes. [Economic Theory of Land Rent and Diverse Labor Types]: Engländer extends his model to include non-homogeneous labor and land as a limited resource. He discusses the formation of 'scarcity rent' (Seltenheitsrente) and 'differential rent' (Unterschiedsrente), explaining how capital distributes itself between industry and agriculture based on the law of diminishing returns and consumer demand, and how population growth or capital increases shift the balance between wages, interest, and rent. [Prices in Single-Stage Capitalism and the Equation of Exchange]: This section analyzes how single-stage capitalist production influences price structures and absolute prices using the equation of exchange. Engländer derives formulas for the velocity of money and total price sums, accounting for the circulation of money as both capital and consumption funds, and examines how the interest rate and wage struggles determine the distribution of income between workers and capitalists. [Mathematical Determination of Wages and Prices]: The author provides a mathematical framework for determining wages and prices under various conditions, including single-stage capitalism with uniform labor, the presence of entrepreneurial profit, and the coexistence of capitalist and non-capitalist production. He demonstrates how the price of a good is composed of labor costs, interest surcharges, and potentially rent or profit, all linked back to the total money supply and demand ratios. [The Impact of Interest Rate Changes on Prices and Production]: Engländer explores how changes in the interest rate—driven by saving or labor struggles—affect wages and prices. He argues that in a purely capitalist system, a drop in interest rates is offset by rising wages in the price formula of individual goods, though shifts in demand or the expansion of capitalist methods into non-capitalist sectors can alter relative price ratios. [The Pricing of Natural Resources and the Role of Foresight]: This section discusses the valuation of permanent sources of goods, specifically land. Engländer introduces the concept of the 'foresight number' (Vorsorgezahl) to explain how buyers and sellers determine the price of land based on the number of future harvests or uses they account for, even in the absence of a formal interest rate. [Capital Interest, Land Rent, and Central Bank Policy]: Engländer examines the relationship between interest rates and land rent, arguing that land prices are determined by the inverse of the interest rate. He critiques the idea that central banks can eliminate land rent through interest-free loans, asserting that such a policy would drive land prices to infinity and that rent can only be theoretically neutralized through taxation without destroying the capitalist form. [Pricing of Durable Goods with Limited Lifespan]: The author analyzes the pricing of goods with a limited but multi-period lifespan, such as buildings. He explains how their value is derived from the sum of future uses, limited by the foresight of the buyer, and how, under capitalist conditions, the price of the good and its individual uses (rent) are determined by production costs and the prevailing interest rate through discounting. [Income from Limited-Duration Goods and Commercial Profit]: Engländer concludes the chapter by explaining why the total revenue from the uses of a durable good exceeds its production costs, attributing this to the effectiveness of capital. He also defines commercial profit (Handelsgewinn) as arising from the mediator's role in bridging the gap between producer and consumer, functioning similarly to single-stage capitalist interest. [Zweistufige kapitalistische Erzeugung: Grundlagen und Kapitalbegriff]: Engländer introduces the concept of two-stage capitalist production, where one group of capitalists produces means of production and another group uses them to create consumer goods. He distinguishes between 'liquid capital' (cash/money) and 'bound capital' (means of production/real capital), explaining how the valuation of the latter is necessary for calculating profit even without a direct sale. The section also clarifies that in a multi-stage system, the wage fund is only a portion of the total liquid capital. [Kapitalzins und Mehrwertrate im mehrstufigen System]: This segment analyzes the calculation of the interest rate (profit rate) in two-stage production, highlighting that it is lower than the surplus-value rate (Mehrwertrate) because the divisor includes both wage capital and capital bound in means of production. Engländer argues that while the surplus-value rate is socially significant for labor disputes, the interest rate is economically decisive for capital allocation and loan interest. He explains that capital will shift between stages until the interest rate is equalized across all uses. [Marktanpassung, Quasirente und Einkommensarten]: The author discusses how shifts in demand lead to price changes and capital migration between production stages, a process that takes longer in multi-stage systems than in single-stage ones. He defines 'quasi-rent' as the total profit (minus explicit costs) derived from goods that temporarily behave like goods of fixed quantity during these adjustment periods. He argues for a broad definition of quasi-rent that includes cases where profits fall below the average interest rate. [Änderung der Wirksamkeit des Kapitals und Arbeitslosigkeit]: This section examines the effects of increased capital efficiency (technological progress) in specific stages or across the whole economy. Engländer demonstrates that shifts in the relative labor requirements between stages cause capital and labor to migrate, often resulting in temporary 'technological' unemployment during the transition. He also notes that these shifts can release money (liquidity) or create capital scarcity depending on whether labor moves to a more or less capital-intensive stage. [Geldtheoretische Aspekte: Umlaufgeschwindigkeit und Kredit]: The final segment of the chunk explores monetary dynamics in two-stage production, including the increased velocity of money circulation and the role of credit. Engländer discusses how 'book lending' (Buchleihe) and bank credit facilitate the purchase of means of production through deferred payments (Stundung). He concludes that while such credit doesn't create 'new' physical capital, it enables existing funds to be utilized as capital by bridging trust gaps, and distinguishes the specific inflationary or liquidity effects of central bank notes used for wages versus production goods. [Multi-Stage Capitalist Production with Equal Stage Numbers]: Engländer extends the analysis of capitalist production from two stages to multiple stages (e.g., three stages), assuming an equal number of stages across all goods. He details the distribution of liquid money among capitalists at different stages, the flow of payments for production means and labor, and how the increasing number of stages necessitates larger capital reserves due to potential delays in the transfer process. [Transfer of Claims and Bank Intermediation in Multi-Stage Production]: The author examines how the transfer of claims (Forderungsübertragung) and bank-mediated bookkeeping credits (Buchleihe) can replace physical cash transfers in multi-stage production. Using a five-stage model (A through E), he demonstrates how banks act as clearing houses, reducing the need for liquid cash reserves and effectively increasing available capital by minimizing 'friction' in the circulation process. [Bank Credit, Capital Creation, and the Role of Savings]: Engländer addresses whether banks create capital through bookkeeping credits without prior savings. He concludes that while banks can create credit balances without cash deposits, they do not 'create' capital directly; rather, they facilitate capital increase by freeing up cash reserves. He distinguishes between clearing credits for production means and cash credits for wages, noting that workers generally require cash, which limits the bank's ability to rely solely on bookkeeping entries. [The Impact of Wage Deferral and Multi-Stage Production on Interest]: This section explores the theoretical scenario where workers might wait for their wages until the end of a production period. Engländer argues that while this would eliminate the 'wage fund' (Lohnfond), capital interest would still persist in multi-stage systems due to capital tied up in production means. He defines the determinants of interest rates as independent of the wage fund, rooted instead in the price struggle between capitalists and workers. [Banking Operations: Savings Banks vs. Note-Issuing Banks]: The text distinguishes between pure savings banks (Sparkassen), which lend deposited cash, and banks that provide bookkeeping credits. It discusses how competition and the need for liquidity influence interest rates (Sollzins and Habenzins). Finally, it notes that banknotes issued by central banks function as actual capital because they can be used directly for wage payments, unlike large-denomination notes or bookkeeping entries. [The Equation of Exchange and Price Ratios in Multi-Stage Production]: Engländer concludes the chapter by applying the equation of exchange (Verkehrsgleichung) to multi-stage production. He provides mathematical formulas to determine wages and prices based on labor and interest rates. He argues that changes in interest rates do not directly change the total sum of prices, but rather influence price ratios or occur alongside changes in money supply and velocity. [Verschiedenstufige kapitalistische Erzeugung: Preisbildung und Zins]: Engländer transitions from the assumption of uniform production stages to multi-stage capitalist production. He explains how the price of consumer goods is influenced by the distribution of labor across different stages and the total number of stages required for production. A key thesis is that goods requiring more labor in earlier stages or a higher total number of stages will command higher prices due to the compounding effect of interest (Zins vom Zins). [Einfluss der Zeitdauer und Zinsfußänderungen auf das Preisverhältnis]: Using examples of goods with different production timelines, the author demonstrates how interest rates affect relative prices. He argues that an increase in the interest rate disproportionately raises the price of goods with longer production cycles or those where labor is concentrated in early stages. Conversely, a drop in interest rates lowers the relative price of such goods. [Dauerhafte Erzeugungsmittel: Anlagekapital vs. Betriebskapital]: The analysis expands to include durable means of production that last across multiple periods. Engländer distinguishes between fixed capital (Anlagekapital) and working capital (Betriebskapital), explaining how the value of durable goods is partially transferred to products. He provides a tabular comparison of capital requirements across different production structures, showing that durable means of production increase bound capital relative to liquid capital. [Abrechnungsverkehr und Beharrungszustand bei dauerhaften Gütern]: This section discusses how clearing systems (Abrechnungsverkehr) and credit transfers function when durable production means are used. Engländer explains that a 'steady state' (Beharrungszustand) must be reached—where replacement matches depreciation—for clearing to fully replace cash payments. Until this state is reached, or during the introduction of new durable goods, deferred payments (Stundung) or cash are necessary. [Bewegungserscheinungen: Nachfrageverschiebungen und Kapitalbedarf]: Engländer analyzes the dynamic effects of shifting demand between goods with different production stage counts. He argues that moving demand toward goods with more stages requires an increase in both liquid and bound capital. This necessitates 'economic saving' (volkswirtschaftliches Sparen)—a temporary reduction in consumption to build up the necessary intermediate production goods—which eventually leads to a new equilibrium with a potentially lower interest rate but the same social product distribution. [Detaillierte Analyse des Übergangsprozesses zwischen Produktionsstufen]: A granular step-by-step numerical example illustrating how labor and capital migrate between different production stages (from a 3-stage to a 6-stage process). The author tracks the reallocation of workers and the resulting temporary shortage of consumer goods, demonstrating how the burden of this transition falls on the capitalists' consumption capacity (Genussvermögen) rather than the workers' wages. [Geldvermehrung, Bankkredit und Notenbankdarlehen in der Stufenproduktion]: The final section of the chunk examines how monetary expansion and banking mechanisms interact with multi-stage production. Engländer argues that while clearing and private bank credit cannot create the additional capital needed for more complex production stages, central bank loans (Notenbankdarlehen) can. However, using central bank credit for this purpose leads to rising consumer prices and a shift in the distribution of the social product in favor of capitalists at the expense of workers. [Determination of the Number of Production Stages in Free Capitalist Production]: Engländer examines how the number of production stages is determined in a free capitalist economy where multiple production paths are possible. He argues that the chosen number of stages depends on technical productivity and the prevailing interest rate; a production extension (detour) is only undertaken if the resulting increase in yield exceeds the interest costs of the additional capital commitment. He uses a fishing net example to illustrate how competition aligns the number of stages with the general interest rate. [The Relationship Between Production Detours and Capital Interest]: This section explores whether the productivity of production detours explains the existence and level of capital interest. Engländer concludes that while multi-stage production is a factual prerequisite for capitalism (by separating workers from the final product market and requiring 'waiting' capacity), it does not explain the origin of interest itself, as interest can exist even with fixed production stages. He critiques the idea that the interest rate is strictly determined by the marginal productivity of the last production detour. [Physical Yield vs. Quality Improvement in Production Detours]: Engländer distinguishes between production detours that increase the quantity of goods and those that improve quality (e.g., aging wine). In the case of quality improvements, the price difference between the higher and lower quality goods adjusts through market competition until it matches the interest costs associated with the longer production duration. He emphasizes that the interest rate remains the primary factor that determines which quality improvements are economically viable, rather than the quality improvement determining the interest rate. [Economic Dynamics Under Free Production Stages: Technical Progress]: This section analyzes the effects of technical progress when production stages can vary. Technical progress that increases the number of stages requires additional capital, which can be sourced from the consumption funds of capitalists or workers (saving). Engländer details the shifts in the social product's distribution between classes during the transition to a new equilibrium and how technical progress can lead to higher real wages even if the workers' relative share of the social product decreases. [The Role of Credit and Central Banks in Production Extensions]: Engländer discusses how central bank credit (banknote issuance) can facilitate the transition to longer production processes. Unlike commercial bank credit based on book entries, central bank loans can provide the necessary liquidity to pay for factors of production during the extended period. He notes that while this increases the money supply (inflationary pressure), the resulting increase in goods from technical progress may offset the price effects. He also contrasts capital creation via saving versus monetary expansion. [Summary of Capital and Money Dynamics in Fixed vs. Free Production Systems]: A comprehensive summary comparing the effects of capital changes and money supply increases in systems with fixed versus free production stages. Engländer outlines various scenarios (saving, central bank loans, technical progress) and their impacts on interest rates, the distribution of the social product between workers and capitalists, and the general price level. He concludes by refining the definition of 'production detour' to account for diverse types of labor and resources. [Economic Fluctuations: The Nature of Depressions and Unemployment]: Engländer defines economic fluctuations (Konjunkturen) as the alternation between booms and depressions, identifying the underutilization of production factors as the core characteristic of a slump. He examines why labor and capital remain idle despite scarcity, rejecting simple technical progress or temporary shifts in production stages as sufficient explanations for systemic unemployment. He argues that the difficulty of reallocating labor across different branches of production, combined with wage rigidities and the paralysis of money capital, leads to a self-reinforcing contraction of demand. [The Mechanics of the Business Cycle: Booms, Downturns, and Capital Investment]: This section explains the cyclical nature of the economy by focusing on the temporal mismatch between the initial acquisition of durable capital goods and their subsequent replacement. Engländer demonstrates how a transition to more 'roundabout' production methods (higher stages of production) initially creates a boom through increased labor demand, but inevitably leads to a downturn once the new capital stock is completed and replacement demand is not yet due. He further discusses how monetary expansion (Geldschöpfung) is a necessary condition for the boom, as it provides the additional purchasing power required to mobilize idle resources. [Monetary Policy, Speculation, and the Possibility of Stable Growth]: Engländer concludes by analyzing whether economic cycles are inherent to capitalism. He distinguishes between general economic fluctuations and specific crises caused by speculation or bank runs. While a stationary economy might avoid cycles, he argues that capitalism is inherently progressive and dynamic. He suggests that cycles are not strictly inevitable if the transition to new production methods is financed through continuous saving rather than pure credit expansion at the peak of a boom. However, he warns that a rigid refusal of credit expansion by central banks might prevent recovery from depressions without necessarily preventing the initial downturn.
