Economic development is the study of how countries improve the economic, political, and social well-being of their people. Unit 7 explores the history of industrialization, how the global economy is organized, and different theories explaining why some regions are wealthier than others.
Economic Sectors
What are the five sectors of the economy?
- Primary Sector: Activities that directly extract materials from Earth (e.g., agriculture, mining, fishing, forestry).
- Secondary Sector: Manufacturers that process, transform, and assemble raw materials into useful products (e.g., factories, construction).
- Tertiary Sector: Provision of goods and services to people in exchange for payment (e.g., retail, banking, law, education).
- Quaternary Sector: Knowledge-based services focusing on information processing and exchange (e.g., research, IT development, finance).
- Quinary Sector: High-level decision-making and leadership roles (e.g., government heads, corporate executives, scientific directors).
Theories of Location and Development
What is Weber’s Least Cost Theory?
Proposed by Alfred Weber, the Least Cost Theory predicts where an industry will locate based on three factors: transportation costs, labor costs, and agglomeration (clustering with other businesses).
- Bulk-Reducing Industry: The finished product is lighter or smaller than the raw inputs (e.g., copper smelting, paper mills). The factory locates near the raw materials to save on shipping heavy inputs.
- Bulk-Gaining Industry: The finished product is heavier or larger than the raw inputs (e.g., soda bottling, car assembly). The factory locates near the market because it is cheaper to ship the raw ingredients/parts than the finished bulk product.
Development Models
What is Rostow’s Stages of Growth vs. Wallerstein’s World Systems Theory?
Geographers use different models to explain national development:
- Rostow’s Stages of Growth (Modernization Model): A five-stage liberal model proposing that all countries can develop economically by proceeding through linear stages:
- Traditional Society: Subsistence agriculture, high military spending.
- Preconditions for Takeoff: Elite group initiates investments in infrastructure.
- Takeoff: Rapid growth in a few specialized manufacturing fields.
- Drive to Maturity: Technology diffuses to all sectors, workers specialize.
- Age of High Mass Consumption: Shift from heavy industry to consumer goods and services.
- Wallerstein’s World Systems Theory (Dependency Model): A structural model proposing that the global economy is a single unit divided into three tiers, with wealthy nations exploiting poorer ones:
- Core: Developed countries that control global finance and consume resources (e.g., US, Japan).
- Semi-Periphery: Countries with emerging economies that manufacture goods but are still exploited (e.g., Brazil, China, India).
- Periphery: Developing countries that export cheap raw materials and provide low-wage labor to the core (e.g., Congo, Cambodia).
Unit 7 Practice Questions
Question 1
According to Alfred Weber’s Least Cost Theory, a soda bottling plant is a bulk-gaining industry and should locate:
A) Close to the raw water source
B) Close to the energy grid
C) Close to the market (consumers)
D) In a region with cheap labor
Question 2
Wallerstein’s World Systems Theory divides the global economy into three tiers. Which tier represents countries with emerging economies that manufacture and export goods but still experience resource drain from wealthier nations?
A) Core
B) Periphery
C) Semi-Periphery
D) Underdeveloped
Answer Key
- C — Bulk-gaining industries locate near markets because the final product (filled bottles) is heavier and more expensive to ship than the ingredients.
- C — The Semi-Periphery acts as a buffer and intermediate tier between the dominant Core and exploited Periphery.
