This paper analyzes the impact of the German autobahn net on the economic performance of German regions. To address endogeneity and reverse causation problems, we use historical instrument variables, i.e. a plan of the railroad net in 1890 and a plan of the autobahn net in 1937. We find a...

Group 1 metal and chemical industries formed the essential suppliers of British war materials during WW2. Their industrial sectors covered metal manufacture, general and electrical engineering, vehicle production, aircraft production, shipbuilding, metal goods, chemicals and explosives, and...

Using novel longitudinal data, this paper studies the short- and medium-term effects of Russia's invasion of Ukraine on February 24, 2022 on social trust of adolescents in Germany. Comparing adolescents who responded to our survey shortly before the start of the war with those who responded...

The British engineering industry experienced extreme production and employment pressures during the rearmament period that preceded the Second World War and in the early war years. Did it react by placing a greater emphasis on incentive-compatible payment methods? This paper examines the...

Between mid-1939 and mid-1943 almost 2.2 million additional women were recruited into Britain's essential war industries. These consisted, predominantly, of young women recruited into metal and chemical industries. Much of the increased labour supply was achieved through government directed...
