The recent refugee crisis has fuelled discussions about policies restricting immigration. This column quantifies the extent to which asylum policies affect emigration by analysing the migration decisions of German Jewish refugees in the 1930s. Policies have large effects on migration as the effects are multiplied through peers who influence each other in the decision to emigrate. Removing work restrictions for refugees in the recipient countries after the Nuremberg Laws in 1935 would have led to a 28% increase in Jewish emigration out of Germany.

In conflicts, adversaries aim for victory by using both direct and indirect forces to break the enemy’s will to resist. During WWII, Allied forces used strategic bombing and radio propaganda to undermine German morale. This column compares German domestic resistance to the Nazi regime, based on treason trial records, with the monthly volume of bombing and the locations of BBC radio transmitters. Where radio reception was better and Allied air forces bombed more heavily, German domestic resistance was markedly more likely, despite the draconian punishments for even the mildest transgressions.

The procedures for relocating forced migrants differ considerably across countries, and information about how resettlement locations within host countries affect integration outcomes remains scarce. And yet, the number of forced migrants around the world increased dramatically over the last decade and continues to grow. This column studies displaced Germans after WWII and finds they fared poorly when relocated to agrarian regions with high migrant density. The authors recommend that current resettlement policies avoid directing large concentrations of migrants to a limited selection of rural areas.

On the 75 anniversary of the VE Day, David Edgerton tells Tim Phillips that Britain's belief in its go-it-alone scientific and inventive genius is “deluded”, and has stunted the nation's postwar growth.

WWII was the last time that Western societies were mobilised for an all-consuming conflict that demanded years of sacrifice and service from every citizen and every family. Such watershed moments are sometimes neglected in economics. This column presents a new VoxEU eBook that brings together recent research on a range of aspects of the war including the extensive war preparations of the great powers, the conduct of the war – including the management of economic mobilisation, economic warfare, economic exploitation, and the role of economists – and the war’s consequences for demography, inequality, economic recovery, and political attitudes.

Countries worldwide are scrambling to procure medical supplies in response to the COVID-19 pandemic. Several governments have called on non-specialist firms to produce medical ventilators. This column draws three lessons from US munition production in WWII. First, ramping up production takes time, particularly for non-specialist producers. Second, international cooperation is needed to share knowledge on production technology and supply chains. Third, direct public investment in plant expansions should be part of the strategy.

Governments of modern states need to convince men and women to fight and possibly to die for their country, putting aside their ‘selfish’ instinct to stay alive. This column examines whether welfare spending under Roosevelt’s New Deal boosted US patriotism during WWII. It finds that higher welfare spending prior to 1940 is positively correlated with greater patriotism, as measured by war bond purchases, volunteering for the US Army, and exceptionally brave acts in battle. The findings suggest that when the federal government looks out for its citizens’ needs, men and women who benefit repay the largesse by becoming more patriotic.

Can the experience of being uprooted by force encourage people to invest in portable assets such as education? The idea has a long history but is a difficult hypothesis to test. This column combines data from historical censuses with newly collected survey data to show that Polish people with a family history of forced migration as a result of WWII are significantly more educated today than any comparison group. The results suggest a shift in preferences toward investment in human rather than physical capital, and imply that the benefits of providing schooling for forced migrants and their children may be even greater – and more persistent – than previously thought.

The year 1945 marked the end of the worst military conflict in history, which brought unprecedented destruction and loss of life. However, the quarter-century that followed is known as the most remarkable period of economic growth and social progress in Europe. This column, part of a Vox debate on WWII, lays out three factors that made this paradox possible: the strong foundations of economic recovery in Western Europe, vital support for the reconstruction of European trade and cooperation, and Allied support for the revival of the German economy. In contrast, Eastern Europe could barely recover due to the demographic disaster from the war.

Economic warfare was widely used in WWII. When one country blockaded another’s supply of essential goods or bombed the industries producing them, why did the adversary’s economy fail to collapse? This column, part of the Vox debate on the economics of WWII, reviews Mançur Olson’s insights, which arose from the elementary economic concept of substitution. He concluded that there are no essential goods; there are only essential uses, which can generally be supplied in many ways.

During World War II aircraft production in Japan increased sharply. This column, part of the Vox debate on the economics of WWII, examines the reasons for this ‘production miracle’, focusing on an aircraft manufacturing plant of Mitsubishi Heavy Industries Co., one of the two largest aircraft producers in Japan. The key to the production increase was the expansion of the supplier network. Mitsubishi Heavy Industries organized many suppliers to provide aircraft parts to its plants. However, in the final stage of the war, destruction of the supplier network by strategic bombing and an earthquake caused the collapse of the company’s aircraft production.

The US became the ‘arsenal of democracy’ by producing a massive amount of military goods that raised real GDP by 72% between 1940 and 1945. Yet, multiplier estimates for this expansion in government spending are less than one. Long-range studies at subnational levels show that military spending was associated with small effects on per capita activity. Military spending in the context of a quasi-command economy crowded out private consumption and investment and forced people into the military. In essence, Americans sacrificed heavily to win the war, while their Allies sacrificed even more.

Neutrality has long been viewed as impartiality in war. This column, part of the Vox debate on World War II, asserts that neutral states in the war were realist in approaching their defence to ensure their survival. Neutrals such as Portugal, Spain, Sweden, and Switzerland maintained independence by offering economic concessions to the belligerents to make up for their relative military weakness. Economic concessions took the form of merchandise trade, services, labour, and capital flows. Depending on their position and the changing fortunes of war, neutral countries could also extract concessions from the belligerents, if their situation permitted.

World War II sharply reduced income and wealth inequality in many countries. This column, part of a Vox debate on the economics of WWII, describes how various factors converged to produce this outcome. Mass mobilisation raised demand for labour and reduced skill premiums, extremely high marginal tax rates cut into elite incomes and fortunes, aggressive government intervention curtailed corporate and investment profits and sought to protect workers, consumers, and renters. Returns of capital fell as international markets suffered interruptions and physical assets risked confiscation or destruction. Communist regimes expanded their reach. In market economies, the war experience promoted reforms regarding social welfare, unionisation and taxation that sustained several decades of greater equality.

Allied victory in WWII is usually viewed through the lens of large land battles, from Stalingrad to Kursk to D-Day. However, battlefield losses of equipment in these ‘great’ land battles were relatively small and easily replaceable. This column demonstrates that the real effort of the major powers was put into the construction of air and sea weapons. The Allies used their air and sea power to destroy the Axis’s in a multi-layered campaign. This was the true battlefield of WWII: a massive air-sea super battlefield that stretched for thousands of miles. Victory in this super-battlefield led to victory in the war.

The World Wars precipitated unprecedented economic problems in all countries. This column, part of a Vox debate on the economics of WWII, describes how economists played a larger role in WWII than in any previous conflict. They advanced the methods of public finance and influenced the directions of the war effort. By the end of the war, economists were widely embedded in government and policymaking.

Of WWII’s warring powers only the Soviet Union suffered mass starvation, but as this column, part of a Vox debate on the economics of WWII, describes, it is a measure of the war’s global reach that 20 to 25 million civilians died of hunger or hunger-related diseases outside Europe. In Britain effective rationing ensured a ‘fair’ distribution of food supplies throughout the war and in Germany the famine conditions experienced in 1918-19 were not replicated, but Japan was facing semi-starvation at war’s end. In Europe, apart from Greece and the Soviet Union, famine mortality was modest, but 3-5% of the populations of faraway Bengal, Henan, and Java perished.

Taken together, the economies of the Nazi-occupied countries were roughly twice the size of the German economy, but Berlin obtained less than 30% of its war expenditures from them. This column, part of a Vox debate on the economics of WWII, argues that in that sense exploitation failed, but the way Germany tried to exploit its empire had important consequences. In Western Europe, where productivity was higher and Berlin took a substantial share of production, mortality was limited and postwar recovery was rapid. In Poland and the USSR, where productivity was lower, continuous warfare and Nazi racism spread destruction and raised mortality, impeding recovery.

Copyrights grant publishers exclusive rights to content for almost a century. In science, this can involve substantial social costs by limiting who can access existing research. This column uses a unique WWII-era programme in the US, which allowed US publishers to reprint exact copies of German-owned science books, to explore how copyrights affect follow-on science. This artificial removal of copyright barriers led to a 25% decline in prices, and a 67% increase in citations. These results suggest that restrictive copyright policies slow down the progress of science considerably.

During WWII the BBC was actively engaged in fostering opposition to the German occupation throughout Europe. This column uses data on variations in radio signal strength during the war to analyse the role played by the BBC’s “Radio Londra” programme in civilian and partisan resistance against the Nazi-fascist regime. The findings suggest that BBC radio played a significant role in coordinating resistance activities against foreign occupation, but only a minor role in mobilising the civilian population against the fascist regime.
