Controversies in the Theory of Capital
The theory of capital is a fundamental aspect of economics, but it has been subject to numerous controversies throughout its history. These controversies have shaped the way economists understand capital, its role in economic growth, and its distribution.
1. Definition of Capital
- Austrian School: Defines capital as heterogeneous, durable goods that are used to produce other goods.
- Neoclassical School: Defines capital broadly as any input used in production, including both physical assets (machinery, buildings) and human capital (knowledge, skills).
- Marxian School: Defines capital as the means of production owned by capitalists and used to exploit workers.
2. Capital and Economic Growth
- Neoclassical: Views capital as a crucial factor of production that drives economic growth.
- Keynesian: Emphasizes the role of aggregate demand in stimulating growth, arguing that capital investment is a component of demand.
- Marxian: Capital accumulation is seen as a driving force of capitalism, but also as a source of inequality and exploitation.
3. Marginal Productivity of Capital
- Neoclassical: Assumes that the marginal productivity of capital (MPK) is positive and diminishing, meaning that adding more capital will increase output but at a decreasing rate.
- Cambridge School: Challenges the assumption of diminishing MPK, arguing that capital can have positive externalities on productivity.
- Post-Keynesian: Emphasizes the role of uncertainty and imperfections in the capital market, which can lead to deviations from the neoclassical MPK curve.
4. Capital and Income Distribution
- Neoclassical: Capital is seen as a factor of production that earns a return in the form of interest or profit.
- Marxian: Capitalists are believed to use their ownership of capital to extract surplus value from workers.
- Piketty: Argues that the return on capital tends to exceed the growth rate of the economy, leading to increasing inequality.
5. Measurement of Capital
- Physical Capital: Can be measured in terms of quantity or value of physical assets.
- Human Capital: Challenge in quantifying knowledge and skills; often measured using education levels or wage premiums.
- Intangible Capital: Growing recognition of the importance of intangible assets such as patents, trademarks, and reputation.
These controversies highlight the complexity and diversity of perspectives on capital. The ongoing debate has helped refine our understanding of capital's role in economic systems and continues to shape policymaking and economic analysis.
