## Three Numbers That Move Governments

Governments rise and fall on three vital statistics. **GDP, gross domestic product**, is the market value of all **final** goods and services produced within a country in a period. By the expenditure approach:

$$GDP = C + I + G + NX$$

Where $C$ is consumption, $I$ is investment, $G$ is government purchases, and $NX$ is net exports. Only **final** goods count: flour sold to a bakery is excluded to avoid double-counting.

**Nominal** GDP uses current prices, while **real** GDP strips out price changes to reveal actual output growth.

**Unemployment rate** is the share of the **labor force** (working plus actively seeking work) without a job:

$$u = \frac{\text{unemployed}}{\text{labor force}} \times 100$$

**Pitfall:** Students, retirees, and **discouraged workers** who stop searching are excluded from the labor force. Unemployment can fall when people simply give up looking.

## Inflation and GDP Blind Spots

**Inflation rate** is the percentage change in the general price level, tracked via the **consumer price index (CPI)**: the cost of a fixed basket of goods over time. Inflation erodes purchasing power and seeps into wages and contracts.

**What GDP misses:** GDP measures production, not welfare—treat it like a speedometer, not a happiness gauge. It misses unpaid housework, the underground economy, leisure, environmental damage, and wealth distribution.

| Indicator | Measures | Built-in trap |
| --- | --- | --- |
| GDP | Value of final output | Double-counting; nominal vs real |
| Unemployment | Jobless labor force share | Discouraged workers exit denominator |
| Inflation | Price level speed | A slower price rise is not deflation |

**Common pitfall:** Never assume "unemployment fell, so the economy improved" without checking if job seekers simply gave up.

## Practice questions

5 of this lesson's 13 practice questions, with answers. The full set is in the app.

### 1. If many discouraged workers stop looking for jobs, the measured unemployment rate can fall even though no one found work.

**Answer:** True

**Why:** Leaving the search removes them from the labor force, the denominator *and* numerator shrink together, flattering the rate. Falling unemployment is only good news if employment actually rose.

### 2. Order the steps of computing annual inflation with a CPI.

**Answer:**

1. Define the fixed basket of consumer goods
2. Price the basket in the base year (index = 100)
3. Price the same basket this year
4. Divide this year’s cost by the base cost
5. Report the percentage change as inflation

**Why:** Fix the basket, price it twice, compare. Everything else in inflation measurement is footnotes to those three moves.

### 3. Sort each person by their labor-market status.

**Answer:**

- Employed: Works 30 hours a week in a shop
- Unemployed: Lost her job, interviews every week
- Not in the labor force: Full-time student not seeking work, Gave up searching after a year of rejections

**Why:** Unemployed requires *actively seeking*. The discouraged worker and the involuntary part-timer are the statistics’ two famous blind spots, one vanishes from the rate, the other looks fully fine in it.

### 4. A country’s nominal GDP grew 6% while inflation was 4%. Approximately how fast did real output grow?

A. About 2%
B. About 24%
C. About 6%
D. About 10%

**Answer:** A. About 2%

**Why:** Real growth ≈ $6\% - 4\% = 2\%$. Two-thirds of the headline number was just prices going up, which is exactly why economists deflate before celebrating.

### 5. Two countries have identical GDP per capita, and one has far higher life expectancy and leisure. What does that reveal about the indicator?

A. GDP per capita is accurate but should be adjusted for population age
B. One country must be miscounting its GDP
C. GDP measures market production, not welfare
D. The difference must come from inequality, which GDP averages away

**Answer:** C. GDP measures market production, not welfare

**Why:** GDP counts transactions, so it credits the cleanup of an oil spill and ignores the grandparent minding a child for free. It was designed as a production measure and Kuznets warned against reading it as welfare in the very report that introduced it, a caution ignored for eighty years.
