- German GDP per person fell from $9,698 in 1944 to $3,534 in 1946, a drop of about 64%; Japan’s fell from $4,986 in 1941 to $2,711 in 1947 (2011 prices).[1]
- The Marshall Plan gave about $13.3 billion to 16 European countries between April 1948 and June 1952, about $143 billion in 2017 dollars; West Germany received $1.39 billion.[2]
- That aid equalled roughly 1.1% of US GDP a year over 1948–51 and less than 3% of the recipients’ combined national income.[14][3]
- West Germany’s June 1948 currency reform produced about a 93% contraction in the money supply; industrial production rose from 51% to 78% of its 1936 level within six months.[6]
- In Japan, wholesale prices rose 55-fold between 1944 and 1948 before the 1949 “Dodge Line” stabilisation.[9]
- US military “special procurement” during the Korean War earned Japan dollar income equal to 25% of its exports in 1951 and 35% in 1952.[10]
- The 1953 London Debt Agreement cut West Germany’s external debt from DM29.7 billion to DM14.5 billion and capped debt service at 3% of export earnings.[8]
- From 1950 to 1973 Japan’s real GDP grew by an average of 9.3% a year and Germany’s by 5.7%, against 2.9% in the UK.[1]
This chapter looks back. It asks what happened to the two biggest defeated economies of the Second World War, Germany and Japan, after the fighting stopped in 1945. Within 25 years both had become among the richest and fastest-growing economies in the world. People called this the Wirtschaftswunder (economic miracle) in Germany and the “Japanese miracle” in Japan.
The story matters today, because the Marshall Plan remains the benchmark for every post-war reconstruction plan. So it is worth asking what it really did, how big it was, and what else explains the recovery.
1. Background: how the war ended and the occupation began
Germany was defeated in 1945, and Japan surrendered unconditionally in August 1945.[3][13] Both countries were occupied by the victorious Allies. Germany was divided into occupation zones. The three western zones later became the Federal Republic of Germany, or West Germany, while the Soviet zone became East Germany.[3][5][7] Japan was occupied mainly by the United States under General Douglas MacArthur, the Supreme Commander for the Allied Powers (SCAP), who had the final say on policy.[12]
At first, the occupiers wanted to punish and reform. In Japan, SCAP broke up the big business groups (zaibatsu), carried out land reform and oversaw a new constitution in 1947.[12] By late 1947 the priority shifted. Economic crisis in Europe and Japan, and fear of communism, led the United States to focus on recovery instead. In Japan this was called the “reverse course”.[12][13]

2. Where things stand now: the legacy today
As of October 2026, Germany and Japan are rich but slow-growing economies, far removed from the “miracle” years. In 2025, GDP per person was about $60,500 in Germany and $36,000 in Japan, at current prices and exchange rates.[15] The IMF estimates that Germany’s economy grew by just 0.2% in 2025 and Japan’s by 1.2%; it forecasts 1.3% and 0.7% for 2026.[16]
Public debt shows how differently the two have developed. Germany’s general government debt was about 63% of GDP in 2025; Japan’s was about 205%, the highest among large advanced economies.[16] This contrasts with the 1950s, when West Germany’s public debt was below 25% of GNP thanks partly to the post-war debt write-downs discussed below.[7]
The Marshall Plan also lives on as a political idea. When the World Bank, the EU, the UN and Ukraine’s government estimated in February 2026 that rebuilding Ukraine would cost almost $588 billion over a decade,[17] the 1948 programme was the obvious benchmark. In today’s money, the Marshall Plan was worth about $143 billion (in 2017 dollars).[2] The comparison is rough, but today’s reconstruction bills are clearly larger than the famous original.
3. The economy before the war
Both countries entered the war as middle-to-upper-income industrial economies, but neither was as rich as Britain or the United States. In 1938, GDP per person (in 2011 prices) was about $7,960 in Germany and $4,257 in Japan, against $9,988 in the UK and $10,526 in the USA.[1]
Both were already wartime command economies before the shooting started. Germany had price controls from 1936 and food rationing from 1939.[6] German output per hour worked never reached 75% of Britain’s at any point before 1950, partly because many Germans still worked in low-productivity farming.[7] This gap matters later: a country that is behind the technology leader has more room to “catch up”.
During the war itself, measured output kept rising for a while as factories switched to weapons. German GDP per person peaked at $9,698 in 1944; Japan’s peaked at $4,986 in 1941.[1] Germany’s war economy relied heavily on forced labour: estimates reach 8.5 million slave labourers by mid-1944.[7]
4. The economic impact: indicator by indicator
4.1 Output and GDP: the collapse of 1945–47
The defeat was followed by an economic collapse. Germany’s GDP per person fell from $9,698 in 1944 to $3,534 in 1946, about 64% lower and well below even its 1938 level. Japan’s fell from $4,986 in 1941 to $2,711 in 1947, a fall of about 46%.[1]
Industry was hit hardest. In the three western zones of Germany, industrial production fell to about one-fifth of its 1938 level.[3] Even in 1947 it was only about one-third of the 1938 level, and food production per person was 51% of its 1938 level.[6] German coal output in 1947 was still only about half its pre-war level, which mattered because coal was the main fuel for industry, power and heating.[3][7] In 1948, GDP in the three western zones was still only 64% of its 1938 level, while the UK’s was 13% higher than in 1938.[7]
4.2 Physical destruction and the capital stock
Japan’s Ministry of Finance estimates that by the end of the war Japan had lost 25% of its total national wealth, 80% of its ships, 34% of its industrial machinery and 24% of its buildings. Ports, communications and transport were also badly damaged.[9]
In Germany, bombing and the “scorched earth” policy at the end of the war destroyed about 20% of the housing stock.[6] However, Eichengreen and Ritschl argue that West Germany’s productive capital survived surprisingly well. Because so much had been invested during the war, the capital stock fell back to roughly pre-war levels, and “productive capacity in West Germany was as high as before the war” at the start of the boom. Most of the damage was to urban housing.[7]
4.3 Inflation, money and the black market
Both countries faced a monetary overhang: far more money than goods to buy at official prices, because wartime governments had printed money while holding prices down by law.
In Germany, the money supply in 1947 was five times its 1936 level, while official prices were frozen. In the US zone, the official cost-of-living index in May 1948 was only 31% above its 1938 level.[6] This was “repressed inflation”: prices could not rise legally, so goods vanished from shops into barter and black markets. Some German factories paid workers in their own products so the workers had something to barter, and some paid part of wages in coal.[3]
In Japan, inflation was open rather than hidden. Between 1944 and 1948, Bank of Japan notes in circulation rose 20-fold and wholesale prices rose 55.1-fold, according to the Ministry of Finance.[9] Another estimate puts the rise over 1945–49 at 79 times for retail prices and 60 times for wholesale prices.[11] A key driver was lending by the state-owned Reconstruction Finance Bank, which fuelled what was called “reconstruction inflation”.[9]
4.4 The fixes: currency reform in Germany, the Dodge Line in Japan
Germany, June 1948. On 20 June 1948 the Deutsche Mark replaced the Reichsmark in the three western zones. Each person received 40 DM in cash, with a further 20 DM shortly afterwards. Wages, salaries and rents were converted at 1:1, but Reichsmark savings were converted at less than 1:10.[5] The net effect was about a 93% contraction in the money supply.[6] On the same day, price controls were “largely eliminated”, a move championed by Ludwig Erhard, director of economics for the joint British-American zone.[5]
The effect was dramatic. From 21 June, goods could again be bought with money, and empty shop windows began to fill.[5] The industrial production index rose from 51% of its 1936 level in June 1948 to 78% in December. Workers’ absence from work fell from 9.5 hours a week in May 1948 to 4.2 hours in October, because wages could now buy things.[6] Tax rates were also cut: a median earner who faced an 85% marginal rate in 1948 faced 18% by 1950.[6]
The reform was not painless. Prices rose sharply after June 1948, real wages fell and a wave of strikes followed. Unemployment then rose, and the government even considered a job-creation programme.[7] People who had held their wealth as Reichsmark savings lost most of it, because savings were converted at less than 1:10.[5]
Japan, 1949. In December 1948 Washington ordered a nine-point stabilisation programme for Japan, and Joseph Dodge was brought in from the United States as economic adviser to carry it out. The “Dodge Line” of fiscal 1949 had three parts:[10][11]
- A “super-balanced” budget covering the general account, special accounts and state agencies, designed to eliminate deficits and start paying down debt.[10]
- An end to new lending by the Reconstruction Finance Bank.[10][11]
- A single exchange rate of ¥360 to the dollar from April 1949, replacing a tangle of multiple rates, for example ¥420 for raw silk exports but ¥80 for raw cotton imports.[10][11]
At the same time, controls were dismantled. The number of price-control cases fell from 2,129 in March 1949 to 148 by March 1952.[11] A US tax mission led by Professor Carl Shoup redesigned the tax system in 1949, including cutting the top income tax rate from 85% to 55%.[10]
Like Germany’s reform, the Dodge Line caused a “stabilisation crisis”: tight money, more unemployment and bankruptcies of small firms. Japan’s employment index fell from 101 in the first quarter of 1949 to 94 in the third quarter.[11] Historians still debate whether the Dodge Line alone ended inflation.[11]
4.5 Public finances and debt
Both countries ended the war with huge debts, and both saw much of that debt wiped out, in different ways.
In Japan, inflation did much of the work. A 55-fold rise in prices shrinks the real value of debts fixed in yen to a tiny fraction of their former value.[9] The Dodge Line then forced the government to run budget surpluses.[10]
In West Germany, the currency reform wrote down domestic debts, and the London Debt Agreement of 1953 dealt with foreign ones. It cut external debt from about DM29.7 billion to DM14.5 billion, roughly half. Annual debt service was capped at 3% of export earnings, and repayment depended on Germany running trade surpluses.[8] As a result, West Germany’s public debt was only 19.7% of GNP in 1950 and stayed below 25% until the 1970s, while Britain’s was 193.5% in 1950.[7]
Eichengreen and Ritschl argue this difference in “financial inheritance”, rather than very different policies, explains much of why Germany outgrew Britain. Britain’s large foreign debt service weakened its balance of payments; Germany’s did not.[7] On the other side of the ledger, West Germany paid occupation costs of about DM7.2 billion a year and more than $1 billion in reparations and restitution.[6]
4.6 Aid: the Marshall Plan and its size
The Marshall Plan, formally the European Recovery Program (ERP), was passed by Congress in March 1948 and became law on 3 April 1948.[2] Between April 1948 and June 1952 it provided about $13.3 billion to 16 countries.[2] The US Office of the Historian describes the total as “over $12 billion”, and DeLong and Eichengreen give $13.2 billion for 1948–51, depending on which programmes and years are counted.[4][3]
The biggest recipients were the UK ($3.19 billion), France ($2.71 billion), Italy ($1.51 billion) and West Germany ($1.39 billion).[2] Japan was not part of the Marshall Plan; it received separate US occupation aid (known as GARIOA, Government and Relief in Occupied Areas), which ended in 1951.[10]
How big was it? There are three useful ways to measure it:
- For the United States, US nominal GDP added up to about $1,194 billion over 1948–51.[14] So $13.3 billion was roughly 1.1% of US GDP per year (author’s calculation). In 1948, the first-year appropriation of $4 billion compared with a total federal budget of slightly less than $30 billion.[2]
- For recipients, the aid was less than 3% of their combined national income and less than one-fifth of their gross investment.[3] Critics note it was never more than 5% of any recipient’s GNP.[2]
- For West Germany, all US aid (Marshall and other) totalled about $2 billion by October 1954 and peaked at under 5% of national income in 1948–49.[6]
What was it spent on? In the first year, half of Marshall aid went on food. Overall, 60% was spent on food, feed, fertiliser, industrial materials and semi-finished goods; one-sixth on fuel; and only 17% on machinery, vehicles and other items.[3] About 70% of the dollars were spent in the United States.[2] Each recipient also had to put an equal amount of its own currency into a counterpart fund, which could only be spent with US approval.[3]
4.7 Trade and the Korean War boom
Before the Marshall Plan, Western Europe faced a “dollar gap”: it needed American food, fuel and machines but had too little to sell in return. In 1947–48 Europe had only 40% of the capacity to import that it had possessed in 1938.[3] Marshall dollars eased this constraint, and the programme also pushed Europe to trade more with itself. In its first year, the Economic Cooperation Administration even paid for European countries to buy goods from each other.[2]
For Japan, the turning point was the Korean War, which began in June 1950. Japan became the main supply depot for UN forces. One US occupation official said “Korea came along and saved us”.[12] The US military paid for goods and services in dollars. According to the Ministry of Finance, this “special procurement” (tokuju) brought in dollar income equal to 25% of Japan’s exports in 1951 and 35% in 1952.[10] Balance-of-payments figures compiled by Haruhito Takeda put special procurement receipts at $592 million in 1951 and $824 million in 1952, compared with merchandise exports of $1,358 million and $1,295 million; the ratios differ from the Ministry’s because of different definitions.[11]
Profits soared. The return on equity in cotton spinning jumped from 26% in the second half of 1949 to 156% in 1950.[11] Japan’s real gross national expenditure rose from ¥14.2 billion in 1948 to ¥18.2 billion in 1951 (in 1934–36 prices), passing pre-war levels.[10] The dollars let Japan import raw materials without hitting a balance-of-payments limit.[10] In Europe, the Korean War had a different effect: from September 1950 a growing share of US aid was redirected towards rearmament, and shortages of materials pushed up inflation.[2]
4.8 Labour market and population
Both countries faced a flood of people needing work. In Japan, 7.61 million soldiers were demobilised, 4 million war-industry workers lost their jobs and 1.5 million people returned from former colonies. The Ministry of Finance estimates that Japan faced the prospect of 17% of its employed population suddenly being out of work.[9] Japan’s population rose by 11 million in 1945–50, while employment rose by only 3.3 million over 1940–50.[11] Many returnees went back to family farms, which hid unemployment.[9]
In West Germany, returning soldiers and refugees expelled from territories lost to Poland, the Soviet Union and other parts of Eastern Europe swelled the population to almost 20% above the 1939 census level.[7] Unemployment was 11.0% in 1950, but it fell steadily to 1.3% by 1960. Britain’s stayed between 1% and 2% throughout the decade.[7]
Eichengreen and Ritschl suggest that high unemployment helped unions accept moderate wage rises in exchange for high investment, though this effect weakened over time.[7]
4.9 Living standards and human capital
Official food rations in occupied Germany ranged from 1,040 to 1,550 calories a day.[6] Western Europe in 1946–47 had about four-fifths of its 1938 food supply, while its population had grown by over a tenth.[3] In Japan, households spent 72% of their consumption on food and drink in 1946, falling to 47% by 1960 as incomes rose.[11]
Human losses were huge. Japan’s Ministry of Finance records 1.14 million army and 410,000 navy deaths, and 300,000 civilians killed in air raids; total casualties including wounded and missing reached 2.53 million.[9] Yet both countries kept a skilled, educated workforce. This human capital helps explain why recovery was so fast once the system worked again.
4.10 Growth in the 1950s and 1960s: the miracle years
Once stabilised, both economies grew very fast. West German GDP rose by nearly 8% a year between 1950 and 1959, faster than anywhere else in Europe, roughly doubling living standards in a decade.[7] By 1958 industrial production was more than four times its level in the six months before the currency reform.[6]
Japan’s boom lasted longer. According to the Maddison Project Database, Japan’s real GDP grew by an average of 8.8% a year in the 1950s and 10.5% a year in the 1960s. Germany’s slowed from 7.7% to 4.2%. For comparison, the UK grew by under 3% a year in both decades.[1] Japan’s GDP per person rose more than fivefold, from $3,062 in 1950 to $15,484 in 1970 (2011 prices).[1]
5. What went well and what went wrong
What went well
- Ending repressed and open inflation quickly. Post-WWII price stabilisation in Western Europe took about four years, compared with Germany’s hyperinflation six years after the First World War and eight years of French inflation after it.[3]
- Getting prices working again. Germany’s combined currency reform and price decontrol brought goods back to shops and workers back to work within months.[5][6]
- Debt relief. The currency reform and the London Agreement left West Germany with low debt and a strong balance of payments.[7][8] The 1953 deal was linked to Germany’s ability to export, which protected growth.[8]
- Multi-year, conditional aid. Unlike earlier relief, which could be cut off at any time, the Marshall Plan was a multi-year commitment, so governments could plan around it.[3] Counterpart funds gave the US leverage to push for balanced budgets and freer markets.[3]
- Trade integration. The Plan encouraged intra-European trade and the European Payments Union.[2] By the end of 1951, industrial production in Marshall Plan countries was 35% above 1938, beating the 30% target, and 55% above 1947.[2]
- A single, realistic exchange rate in Japan. The ¥360 rate replaced multiple rates that had subsidised some sectors and hidden costs.[11]
What went wrong or was costly
- Two to three lost years. From 1945 to 1948, controls on prices kept goods off the market, encouraging barter and absenteeism.[3][6]
- Savers lost heavily. Converting savings at less than 1:10 in Germany, and 55-fold price rises in Japan, wiped out the wealth of people who held money or bonds.[5][9]
- Stabilisation crises. Both reforms brought a rise in unemployment and, in Germany, strikes over falling real wages.[7][11]
- Agriculture lagged. By 1951 food production in Marshall Plan countries was only 11% above pre-war, and Europe could still not feed itself.[2]
- Recovery depended partly on another war. Japan’s take-off owed a great deal to Korean War spending, which was not a repeatable policy.[10][12]
6. The economics behind it
6.1 Why did these economies grow so fast? Three schools of thought
Eichengreen and Ritschl group explanations of Germany’s 1950s boom into three schools.[7]
- Catch-up (convergence). Germany was behind Britain and the US in productivity and still had many workers in farming. Moving labour into industry and adding capital raises output fast until the gap closes. This is what the Solow growth model predicts.
- Institutional shake-up. War and occupation broke up cartels and lobbying groups, and reforms created competitive markets.
- Reconstruction (bounce-back). The war pushed output far below its long-run trend. Because capital and skills survived, output could grow very fast simply by returning to trend. The bigger the fall between 1938 and 1950, the faster the later growth.
Their own evidence favours the reconstruction view and finds “little support” for the institutional shake-up explanation.[7] Between 1946 and 1950, total factor productivity (output per unit of all inputs) grew by 15–20% a year, far faster than normal, consistent with idle capacity being brought back into use.[7]
6.2 Was the Marshall Plan decisive? The debate
DeLong and Eichengreen’s famous paper argues that the Marshall Plan was “not large enough” to have significantly accelerated recovery by financing investment or rebuilding infrastructure.[3] Their reasoning:
- Eichengreen and Uzan estimate that each dollar of aid raised consumption by about 65 cents and investment by about 35 cents.[3]
- Aid of about 3% of output raised the investment share by about one percentage point. That would raise growth by about half a percentage point a year.[3]
- Over four years, this adds up to national income only about 2% higher than it would otherwise have been. Valuable, but “too little to make the difference between prosperity and stagnation”.[3]
Instead, they call it “history’s most successful structural adjustment program”. Its real effect came through conditions: it pushed governments towards balanced budgets, price decontrol, stable currencies and open trade, leaving Europe’s mixed economies with “more ‘market’ and less ‘controls'”.[3] Aid also helped settle “wars of attrition” between social groups over who would bear the cost of stabilisation: by covering part of the gap, it made compromise easier.[3]
Others see a larger role. The CRS notes that average GNP in recipient countries rose by about 33% during the four years of the Plan and that investment stayed around 20% of GNP, one-third above the pre-war rate. It describes the Plan as a “stimulus that set off a chain of events”, while noting the weak statistical link between aid received and growth.[2] DeLong and Eichengreen themselves point out that growth was fastest where US influence over policy was strongest, in Germany, and slowest where it was weakest, in Britain.[3]
6.3 Inflation, the quantity theory and currency reform
The quantity theory of money says MV = PY: the money stock (M) times how often it is spent (V) equals the price level (P) times real output (Y). If M rises five-fold and the government freezes P by law, the equation cannot balance through official markets. Instead, V collapses (people hoard money that buys nothing), goods disappear into barter, and Y falls. Germany’s currency reform cut M by about 93% and freed P at the same time, so money became worth earning again.[6] Japan took a different route: it let P rise (open inflation) until the Dodge Line cut the growth of M by ending deficit finance and new state lending.[9][10]
6.4 Debt overhang and the London Agreement
A debt overhang happens when debts are so large that investors expect future profits to be taxed away to pay creditors, so they hold back. The 1953 London Agreement removed this risk for West Germany by halving foreign debt and linking repayments to export earnings.[8] Stuckler and co-authors conclude: “While there had been a problem of debt prior to 1953, a decade later there was none”. They caution that success also depended on the 1948 currency reform, the European Payments Union and Cold War politics.[8]
6.5 Opportunity cost for the donor
For the United States, the Plan had an opportunity cost: about 1.1% of GDP a year that could have been spent at home.[14] But because about 70% of the dollars were spent on American goods, part of the money returned as US export demand.[2]
7. Outlook and the way forward: lessons for reconstruction today
What can today’s post-war economies learn from 1945–1970? The evidence in this chapter points to five lessons, each with limits.
- Stabilise money first. Neither Germany nor Japan recovered until inflation, open or hidden, was ended. Germany needed a new currency; Japan needed a balanced budget.[5][10]
- Aid works best with reform. The Marshall Plan’s direct financial effect may have been as small as 2% of national income, but its conditions helped lock in good policy.[3]
- Deal with debt early. West Germany’s low debt after 1953 gave it room to invest and export.[7][8]
- Markets for exports matter. Japan’s take-off needed foreign demand (Korean War procurement) and Germany’s needed open European markets.[10][2]
- Surviving capital and skills set the speed limit. Fast “miracle” growth was largely a bounce-back to where these economies would have been without the war.[7]
Scenarios. A country that, like West Germany, keeps much of its capital and skilled workforce, and gets stable money, debt relief and open export markets, can expect a period of very fast “catch-up to trend” growth. If aid arrives but money and institutions stay unstable, aid may mostly finance consumption, as about two-thirds of Marshall aid did, and recovery is slower.[3] If capital, skills and people have been lost on a large scale, or fighting resumes, there is less to bounce back with.
Risks in drawing the analogy. The 1948 programme had special features that are hard to repeat: an occupying power with direct control over policy in Germany and Japan, a Cold War motive that made the US generous,[4][12] recipients with high pre-war human capital, and a booming world economy. Ukraine’s estimated needs of almost $588 billion are several times the Marshall Plan’s value in today’s dollars.[17][2] Both comparisons are rough, but they suggest that a “new Marshall Plan” would need to be much larger in money terms, and that money alone would not be enough.
