The correct option is 1 and 3 only.
Explanation
Economic capital is broadly classified into physical capital (tangible assets like machinery) and human capital (intangible assets like skills, knowledge, and health). While both forms of capital are essential for production, they differ significantly in their depreciation patterns and adaptability to change.
- Statement 1 is Correct: Physical capital is subject to depreciation due to wear and tear over time. Continuous usage leads to the degradation of machinery, buildings, and equipment, necessitating repairs or replacement. This is a fundamental accounting and economic concept.
- Statement 2 is Incorrect: While human capital does depreciate due to aging or the erosion of skills over time, this depreciation can be reduced or managed. Investment in healthcare, continuous education, and on-the-job training helps maintain and even enhance human capital, thereby countering the natural depreciation process. It is not absolute or unmanageable.
- Statement 3 is Correct: Technological advancements often render physical capital obsolete (e.g., a typewriter becoming useless in the computer age). Physical capital cannot "learn" or adapt on its own. In contrast, human capital is dynamic; individuals can acquire new skills and knowledge through investment in education and training to cope with technological changes.
Key Takeaway:
Physical capital depreciates through use and becomes obsolete due to technology, whereas human capital can adapt and evolve through continuous investment in education and health, making it more resilient to obsolescence.
