Wars are expensive, both in human terms and monetary ones. But while warfare might be costly it has also, at times, been an important driver of economic change and progress. Over the long span of history nothing has shaped human institutions - and thus the process of economic development - as much as war and violence.

Blood and Treasure looks at the history and economics of warfare from the Viking Age to the war in Ukraine, examining how incentives and institutions have changed over time. Along the way it asks whether Genghis Khan should be regarded as the father of globalisation, explains how New World gold and silver kept Spain poor, asks if handing out medals hurt the Luftwaffe in the Second World War and assesses if economic theories helped to create a tragedy in Vietnam.
