Apr 2, 2025

Mr. Sin's Lecture: Economic Sectors and Development

Introduction

  • Review of economic sectors and development of states
  • Discussion of Weber's least cost theory and break of bulk points

Economic Sectors

Primary Sector

  • Involves extraction of natural resources
    • Examples: Farmers, coal miners, fishermen, lumberjacks
  • Focus: Extraction, not processing

Secondary Sector

  • Involves processing and manufacturing
    • Uses raw materials from the primary sector
    • Examples: Processing wheat into flour, strawberries into jam
  • Often located near primary sector jobs to reduce transportation costs
  • Commonly found near infrastructure such as railways, highways, ports

Tertiary Sector

  • Based on providing services
    • Examples: Lawyers, doctors, servers, Uber drivers, real estate agents
  • Jobs increasingly provided over the internet
  • Majority of U.S. economy is in this sector

Quaternary Sector

  • Sub-sector of the tertiary sector
  • Focus: Acquiring, processing, and sharing information
    • Examples: Teachers, professors, journalists, finance professionals

Quinary Sector

  • Another sub-sector of the tertiary sector
  • Focus: Decision making
    • Examples: Politicians, corporate executives

Economic Development and Transformation

  • Less developed countries: More jobs in primary sector
  • Industrialized countries: Growth in secondary and tertiary sectors
  • Post-industrial society: Decline in secondary sector, expansion of tertiary sector
    • Example countries: Sweden, Finland

Classification of Countries

  • Core Countries: Advanced economies, high standard of living, tertiary sector jobs
    • Examples: U.S., Canada, European countries
  • Semi-Periphery Countries: Emerging economies, secondary sector jobs
    • Examples: China, Brazil, Mexico, India
  • Periphery Countries: Lower standard of living, primary sector jobs
    • Examples: Many countries in Africa, Middle East, parts of Asia

Global Production

  • Multinational corporations often locate in periphery/semi-periphery countries
    • Due to cheaper labor, loose regulations
  • Use of break of bulk points to lower costs
    • Example: Ports for transferring goods from ships to trucks/trains

Weber's Least Cost Theory

  • Focus: Location of industry based on transportation, labor costs, agglomeration
    • Transportation: Shipping resources and products
    • Labor: Production costs
    • Agglomeration: Clustering for cost reduction
  • Bulk Reducing Goods: Lighter after production
  • Bulk Gaining Goods: Heavier after production
  • Criticism: Oversimplifies factors, ignores government policies, cultural preferences

Conclusion

  • Encourages practicing learned material
  • Suggestions for further resources and engagement (e.g., subscribe, review packet)
