Development

Quick Summary

• Development = progress towards a better quality of life (physical, social, psychological, economic) — it's not smooth, and it can reverse.
• The cycle of wealth shows how economic growth → jobs → taxes → investment → more growth, feeds itself.
• We measure development with GDP, GNP, GNI, HDI, and the Gini coefficient — each has strengths and serious blind spots.
• The development gap exists between and within countries, caused by physical geography, demography, technology, social factors, and government.
• Cumulative causation explains why some regions (the "core") pull ahead while others (the "periphery") fall behind.
• Economic activity splits into four sectors — primary, secondary, tertiary, quaternary — and their balance is a strong clue to a country's development stage.
• The Clark-Fisher model shows employment shifting from primary → secondary → tertiary/quaternary as a country develops.
• Globalisation has "shrunk the world" through time-space compression, driven by TNCs, trading blocs, transport, and the internet.
• TNCs bring both huge benefits (jobs, skills, infrastructure) and real costs (exploitation, profit leakage, loss of control) to host countries.

1. Levels of Development

What actually is "development"?

Here's the thing most students get wrong straight away: development is not the same as being rich. Development means a country's progress towards a better quality of life and greater independence for its population. Quality of life includes things you can't put a price tag on — like happiness, security, and freedom — as well as things you can measure, like income and healthcare access.

Think of development as four interconnected "layers" of a person's life. Pull on one thread and the others move too:

These are interconnected — for example, higher income (economic) can mean better healthcare and environment (physical), which in turn affects happiness (psychological). It's a web, not four separate boxes.

The Cycle of Wealth

The cycle of wealth is described in the chapter as the key indicator of development. It's essentially a self-reinforcing loop: a stable, effective government helps the economy grow → as the economy grows, more people work and earn money → the government collects more tax from this → that tax (plus business profits) gets ploughed back into infrastructure, healthcare, education, and further growth → which fuels the next round of growth.
