Development and well-being indicators
Picture an oil boomtown in West Texas: record output, new pickup trucks everywhere, and also smog, crowded clinics and rents that push families out. Is a place that grows fast also a place where people live better? Growing and living better are not always the same thing: that is why we need to measure beyond GDP.
Growth and development
Growth is part of development: it is one of its pieces, but not the only one.
Explain the difference between economic growth and development. Can a country's GDP grow without improving the lives of the majority? Give a reasoned example.

Two imaginary countries: Kolia has an income per capita of $\$40,000$ and a medium HDI; Osia has $\$28,000$ and a very high HDI.
- a) How is this combination possible? Explain what Osia must be doing right.
- b) Which country would you choose to live in and what criterion do you use to decide?
What GDP leaves out
The same logic explains why GDP can jump after a hurricane on the Gulf Coast: spending on rebuilding counts as output, but the homes and businesses that were destroyed are not subtracted. It also matters for comparisons: if more adults move into paid jobs and families start paying for child care, measured GDP rises even if the total amount of work done hardly changes.

An earthquake destroys part of a city. The following year, the region's GDP rises strongly thanks to reconstruction.
- a) Explain why GDP grows even though residents are worse off than before the earthquake: what does GDP count and what does it not count?
- b) What complementary indicator would better reflect the situation (wealth or assets destroyed, perceived well-being)? Explain your answer.
Other indicators of well-being
Life expectancy at birth is the average number of years a newborn would live if today's death rates stayed the same. If two countries have the same income but life expectancies of 74 and 83 years, look for differences in access to health care, diet, and how unequal incomes are.
The literacy rate is the share of adults who can read and write; mean years of schooling is the average time adults spent in school. Education is both a sign and a cause of development: more schooling means more skills, which means higher productivity, higher income later on and better health choices, which in turn help the next generation stay in school.
The per capita carbon footprint is a country's greenhouse gas emissions divided by its population. It does not describe today's quality of life; it measures the damage passed on to the future, because emissions now warm the climate and affect the health, land and income of the next generations.
What do the literacy rate and the average years of schooling measure? Explain why education is both a sign of development and one of its causes: what chain connects it…

If two neighbors each look after their own children, GDP records nothing; if they decide to pay each other to look after the other's children, GDP rises, even though the work done is the same.
- a) Explain the paradox and what it says about what GDP measures (market transactions).
- b) Reason how this affects GDP comparisons between countries or between periods with different levels of women's participation in paid work.
Building and weighing an index
To compare places on several things at once, you can build a simple index: scale each indicator from $0$ to $1$, then average them with weights.
Objective data for your city could include life expectancy, high school graduation rate, air-quality days, crime rate and average commute time. A survey of residents adds subjective data, such as "How satisfied are you with your life?", because people's own experience of their lives is part of well-being. A practical difficulty is that data for every neighborhood must be collected the same way, and surveys are costly and answers can be biased.
Three fictitious countries: Alia has income per capita of $\$30,000$, life expectancy of $80$ years and $12$ average years of schooling; Bora has $\$24,000$, $82$ years…

You are asked to assess whether your city "is developed" beyond its income.
- a) Propose four objective pieces of data you would collect (health, education, the environment, safety, or cohesion) and explain what each one contributes.
- b) Add a survey of residents: what two questions would you ask about their lives, and why do subjective data count too?

Design a quality-of-life index for your city.
- a) Choose five variables (with their unit of measurement) and explain why each one deserves to be in the index.
- b) How would you weight them? Justify your decision and mention a practical difficulty in collecting the data.
Why GDP is still used
If GDP has so many limits, why does the BEA still publish it every quarter? Because it is clearly defined, measured the same way every year, comparable across countries, and closely tied to jobs, income and tax revenue. Well-being indicators are usually slower to produce, rely on judgment calls or surveys, and are harder to compare. The practical answer is not to drop GDP but to read it alongside other indicators.
GDP growth can also hide real losses. A mining region may post high GDP while air quality falls and young people leave. Looking at life expectancy, air quality and population change gives a fuller picture, and it suggests policies such as cleaner technology or job training that do not shut the activity down all at once.

The president of a country declares in the budget debate: "Our absolute economic priority must be for GDP to grow above 3 %, because when GDP increases, the social well-being and sustainability of a country are automatically guaranteed."
- a) Refute the president's claim by providing two concrete examples where an increase in GDP causes or conceals an actual deterioration in citizens' quality of life.
- b) If GDP has such well-known limitations for measuring well-being, why do the Treasury Department, the Bureau of Economic Analysis, and international organizations continue to use it as the core macroeconomic indicator? Justify at least two operational advantages of GDP compared to composite quality-of-life indices.
- c) Design an alternative dashboard with three key non-monetary indicators and explain what practical measurement or periodicity difficulties the federal government would face when trying to govern based on them.

A region depends on a highly polluting mine: local GDP is high, but air quality is poor, life expectancy is low and young people are leaving.
- a) Assess the region's "well-being" using several indicators, not just economic ones.
- b) Propose two measures to improve its development without shutting down activity all at once.
Two countries: one has high income, very polluted air and extremely long working hours; the other has average income, clean air and more free time. a) What indicators…
Two countries: one has high income, very polluted air and extremely long working hours; the other has average income, clean air and more free time.
- a) What indicators would you ask for, besides income, to decide where to live? Justify each one.
- b) Explain why that decision mixes data and personal judgments, and what that says about "best country to live in" rankings.
Back to the beginning: That West Texas boomtown, with record output but smog and strained clinics, has economic growth but not full development: to judge its real well-being we must look at health, education and its carbon footprint, not just its GDP.
