# The Golden Age of Capitalism

## The Greatest Boom

Between 1945 and 1973, the Western world lived through **unprecedented growth**: European GDP doubled or tripled, Japan surged, and inflation was low. This was the **Golden Age of Capitalism**.

**Bretton Woods** (1944) built postwar monetary architecture: the US dollar pegged to gold at $35$ per ounce, and all other currencies pegged to the dollar. Exchange rates were fixed but adjustable.

| Institution | Role |
| --- | --- |
| **IMF** | Managed balance-of-payments crises |
| **World Bank** | Financed development |
| **GATT** | Liberalised trade, preventing 1930s tariff wars |

**Catch-up growth** (convergence) let war-devastated nations adopt US tech. Solow-model logic applied: low capital stock meant high marginal returns to investment, so importing the frontier was faster than inventing it.

## The Mixed Economy and Collapse

**The mixed economy** combined Keynesian demand management, welfare states, and nationalised industries. The political bargain: capital got stable demand, labour got rising wages.

**Why it ended**: US trade surpluses vanished as rivals recovered, leading to a dollar-gold run. In 1971, Nixon suspended gold convertibility, collapsing Bretton Woods.

| Ingredient | Contribution |
| --- | --- |
| **Bretton Woods** | Stable exchange rates |
| **Catch-up** | Adopting the US frontier |
| **Cheap oil** | Falling energy costs |
| **Social bargain** | High demand and wages |

> **Common pitfall:** Projecting the Golden Age as normal. Catch-up growth is a one-off phase; pushing the frontier itself is slow. When catch-up finished, growth slowed.

## Practice questions

8 of this lesson's 14 practice questions, with answers. The full set is in the app.

### 1. Complete the Bretton Woods structure.

**Answer:** Other currencies pegged to the **dollar**, which was convertible to gold at **35 dollars** per ounce.

**Why:** Dollar peg at 35 dollars per ounce, the hub of the Bretton Woods wheel.

### 2. European GDP per capita roughly **tripled** between 1950 and 1973. If it started at index 100, **estimate the 1973 level.**

**Answer:** 300 (within ±25)

**Why:** Index 300, a tripling in 23 years, roughly 5% annual growth. Nothing like it before or since in Western European history.

### 3. Match each Golden Age concept to its meaning.

**Answer:**

- Catch-up growth → Adopting proven technologies from the frontier
- Mixed economy → Government demand management plus welfare state
- Bretton Woods → Dollar-gold peg with adjustable exchange rates
- Nixon shock → Suspending dollar-gold convertibility in 1971

**Why:** Convergence, the social contract, the monetary architecture, and its collapse, the Golden Age's four pillars.

### 4. Western Europe grew far faster between 1950 and 1973 than either before or since. Which explanation accounts for both the speed and the slowdown?

A. Catch-up growth, which decelerates as the gap closes
B. The Marshall Plan, whose funds ran out in the early 1970s
C. Keynesian demand management, which was abandoned after 1973
D. Post-war reconstruction, which was complete by the mid-1950s

**Answer:** A. Catch-up growth, which decelerates as the gap closes

**Why:** Borrowing a proven frontier is cheaper than pushing it, so the advantage shrinks as you approach, the deceleration is built into the mechanism rather than caused by a separate event. Reconstruction and Marshall aid matter but were finished long before growth slowed, so neither times the turn.

### 5. Why did catch-up growth eventually slow in Western Europe?

A. The easy adoption gains were exhausted
B. The US stopped innovating
C. European governments banned foreign technology
D. Population declined in all European countries

**Answer:** A. The easy adoption gains were exhausted

**Why:** Convergence growth is self-limiting: the closer you get to the frontier, the less low-hanging fruit remains. Further growth requires innovation, not imitation.

### 6. Which conditions made the Golden Age possible?

A. Institutional stability (Bretton Woods, GATT, welfare states)
B. A return to the pre-1914 gold standard
C. Cheap energy (oil was abundant and inexpensive)
D. Enormous catch-up potential after wartime destruction

**Answer:** A. Institutional stability (Bretton Woods, GATT, welfare states); C. Cheap energy (oil was abundant and inexpensive); D. Enormous catch-up potential after wartime destruction

**Why:** Catch-up potential, cheap energy, and institutional design, not the old gold standard, which was explicitly rejected.

### 7. Order the key events of the postwar era.

**Answer:**

1. Bretton Woods conference (1944)
2. Marshall Plan begins (1948)
3. European Economic Community founded (1957)
4. Nixon suspends gold convertibility (1971)
5. First oil shock (1973)

**Why:** Monetary architecture, reconstruction aid, trade integration, system collapse, energy shock, the arc of the Golden Age.

### 8. Under Bretton Woods only the dollar was convertible to gold; other currencies were pegged to the dollar.

**Answer:** True

**Why:** True. It was a gold-exchange standard: the dollar was fixed to gold at 35 dollars an ounce and every other currency pegged to the dollar. That put the whole system's credibility on US reserves, Triffin's dilemma, and it is why Nixon closing the gold window in 1971 ended the arrangement outright.
