Growth, Inequality, and the Liberalization Tradeoff

Liberalizing reforms often make an economy grow fast and make it more unequal at the same time, because the new gains concentrate among people already positioned to capture them. That is why a country's GDP can double while most of its citizens feel no richer.

When a government opens markets, cuts tariffs, privatizes state firms, or deregulates, it usually speeds up growth. But it rarely spreads that growth evenly. People who already own capital, live in cities, or work in export sectors capture the new opportunities first. People in state-protected industries or rural subsistence farming often get left behind or even lose ground. So you get two curves moving in opposite directions: a rising GDP per capita curve, and a rising Gini coefficient, the standard measure of income inequality, where 0 is perfect equality and 1 is perfect inequality.

This is why total output can double while most people report feeling poorer. If the top decile's income share grows from 30 percent to 42 percent of the total, that 12-point jump is concentrated gain. Average income went up, but the median person's experience did not move with the average, because the mean gets pulled upward by a shrinking group at the top. Growth statistics describe the whole pie; they say nothing about who is holding the slices.

This tradeoff connects directly to the unit's bigger question about what governments do when global markets push back. Fast growth with narrowly held gains tends to strain political stability: it fuels resentment, protest, and demand for redistribution, even as the regime points to GDP figures as proof of success. China's post-1980 reforms are the central case: growth curves climbed steeply while its Gini coefficient also climbed, and the state has had to manage the resulting inequality politically, not just economically.

Key terms

Gini coefficient
A measure of income inequality ranging from 0, perfect equality, to 1, perfect inequality.
GDP per capita
Total economic output divided by population, used as an average measure of income or living standards.
Liberalization
Policy shifts that open markets, reduce state control, and expose an economy to global trade and investment.
Income decile
One tenth of a population ranked by income, used to compare how much of total income each tenth holds.
Liberalization tradeoff
The pattern where market-opening reforms raise overall growth but also tend to raise inequality.

  2. Worked exampleShow me China's GDP per capita and Gini coefficient plotted together from 1980 onward.
  3. Worked exampleFind the change in a country's Gini index when the top decile's share moves from 30 to 42 percent.
  4. Going furtherWhat happens to political stability when growth is fast but its gains are narrowly held?

Your turn1 of 2
Using a simplified estimate, a country's Gini index equals (the top income decile's share of total income minus 10) divided by 90. If the top decile's share moves from 30 percent to 48 percent, what is the change in this estimated Gini index?
