Conociendo al capital, John Maynard Keynes

Marina's Shoe Factory and Economic Crisis

Marina's Business Challenges

• Marina has been producing 100 pairs of shoes daily for the past decade, employing 10 workers at full capacity.

• Due to a regional economic crisis, she anticipates that selling 100 pairs is no longer feasible; thus, she decides to reduce production to 50 pairs and cut her workforce in half.

• Other local business owners share her pessimism, leading to widespread layoffs which exacerbate unemployment.

The Roaring Twenties and Stock Market Optimism

• Following World War I, the U.S. emerges as a global power with factories operating at full capacity, creating an atmosphere of optimism known as the "Roaring Twenties."

• Many Americans invest heavily in stocks, believing in continuous growth and substantial profits from their investments.

• However, signs emerge that companies are overproducing beyond demand, leading to excess inventory and workforce reductions.

The Great Depression Begins

• The stock market crash on October 29, 1929 (Black Thursday), marks the beginning of a significant financial crisis affecting all sectors.

• Millions lose jobs and savings as banks fail; the interconnectedness of economies leads to a global downturn.

Global Economic Impact

• Industrialized nations impose protectionist measures while reducing prices for raw materials and agricultural products, impacting exporting countries like Argentina.

• As capitalist profits decline, workers face severe poverty; Marxist predictions about capitalism's weaknesses seem validated.

Keynesian Economics Emerges

• In response to the crisis, economist John Maynard Keynes advocates for abandoning traditional economic theories in favor of state intervention in markets.

• Keynes argues against punitive reparations imposed on Germany post-WWI as they could lead to future conflicts; he emphasizes understanding economic recessions differently than mainstream thought.

Unemployment Perspectives

• In his seminal work published in 1936 ("The General Theory of Employment, Interest and Money"), Keynes presents a new view on capitalism advocating for government intervention during crises.

• He distinguishes between voluntary and involuntary unemployment; involuntary unemployment can be persistent due to insufficient effective demand rather than just temporary market adjustments.

Economic Theories and Demand Dynamics

The Role of Supply in Economic Theory

• The motor driving the economic system is found in the supply of goods, with factories producing based on the principle that "every supply creates its own demand," as summarized by the law of 6.

• Entrepreneurs utilize their full production capacity and hire necessary workers to maximize output, asserting that total supply generates demand through productive activity.

Income Distribution and Consumption Patterns

• Workers receive wages, landowners earn rent, and capitalists gain profits; these incomes enable families to purchase goods, thus generating demand contrary to the law of 6 which posits that demand creates supply.

• Demand for goods arises from two main factors: consumption and investment. It is noted that not all produced goods find buyers due to potential mismatches between supply and persistent insufficient demand.

• Family income influences consumption levels; higher incomes lead to increased spending but also a tendency towards saving, known as the propensity to consume.

Inequality's Impact on Consumption

• In societies with unequal income distribution, consumption propensity decreases because wealthier classes spend less proportionally compared to lower-income groups who consume more of their earnings.

• Advocates for income redistribution policies argue such measures can boost consumption among disadvantaged classes, thereby enhancing effective demand, production, and employment within the economy.

Investment Decisions and Economic Outlook

• Investment decisions are primarily made by entrepreneurs who buy machinery or facilities based on expected future profits; optimistic forecasts lead to increased production capacity while pessimism results in stagnation.

• Entrepreneurial expectations significantly influence investment levels; negative outlook leads to reduced investments resulting in unsold inventory when effective demand declines during crises.

The Cycle of Unemployment and Stagnation

• A cycle emerges where low effective demand causes businesses to produce below capacity leading to unemployment; this further reduces consumption creating a vicious cycle of economic stagnation.

• Without state intervention supporting effective demand, markets cannot self-correct towards equilibrium during downturn periods.

State Intervention Strategies

• Keynesian economics emphasizes that adequate worker salaries are essential for maintaining consumer purchasing power which drives overall market demand.

• To combat unemployment effectively, states should intervene by increasing effective demand through fiscal policies aimed at public spending which stimulates both direct job creation and indirect consumer spending boosts.

• Public infrastructure projects funded by government spending not only create jobs but also enhance future private sector investment by lowering operational costs for businesses.

Investment Decisions and Economic Policy

The Dilemma of Investment Allocation

• Marina faces a decision on whether to invest her increased income into modernizing her plant for higher production or keep it in the bank as a speculative investment.

• Business investment decisions are influenced not only by expected profitability from machinery but also by comparing potential gains against interest rates.

• High-interest rates can deter productive investments, as they represent the cost of borrowing for business expansion.

The Role of Liquidity Preference

• Investors' preference for liquidity leads to high-interest rates, which compete against productive investments due to economic uncertainty.

• To encourage fixed-term deposits, banks raise interest rates, inadvertently discouraging productive investments that could boost demand and employment.

Expanding Monetary Policy

• Geithner suggests an expansive monetary policy where the state injects money into the economy to lower interest rates, stimulating business borrowing and investment.

• Keynesian policies advocating government responsibility for reducing unemployment gain acceptance in academic and political circles.

Historical Context of Keynesian Economics

• Franklin Roosevelt's New Deal exemplifies early state intervention in the economy through active social policies post-Great Depression.

• Post-WWII, Keynesianism flourished globally as governments adopted policies improving living standards through health, education, retirement benefits, and credit access.

Institutional Framework and Economic Coordination

• The Bretton Woods agreements established international coordination mechanisms among major powers to stabilize production and employment post-war.

• Initially aimed at coordination, institutions like the IMF and World Bank shifted towards promoting market liberalization from the 1970s onward.

Impact of Monetary Expansion on Business Decisions

• With reduced interest rates due to expansive monetary policy, businesses like Marina's find it more profitable to invest rather than keep money in low-yield savings accounts.
