Plain-language explanation.
Economic history studies how economies changed over time — from ancient trade networks to the Industrial Revolution to globalisation. Economic historians use historical records, statistics, and economic theory to understand why some countries became wealthy while others did not.
Core concepts and standard treatment.
Economic history combines source-critical methods of history with quantitative and theoretical tools of economics. Cliometrics (Fogel and North) applied econometric methods to historical data. National accounts reconstruction (Maddison Project) enables long-run GDP comparison across centuries and continents. The great divergence between European and Asian income levels is the central puzzle of pre-modern economic history.
Deeper theory, debates and edge cases.
Institutional economic history (North) argues quality of property rights and political institutions explains differential economic performance. The colonial origins of comparative development (Acemoglu, Johnson, Robinson) uses settler mortality as an instrument for institutional quality. Financial history examines banking crises, sovereign defaults, and monetary systems.
How it is applied in practice.
Economic history datasets (Maddison, FRED, World Bank Open Data) are widely used in economic research. Business historians analyse corporate strategy and entrepreneurship using archival sources. Economic history provides natural experiments — gold standard adherence, tariff changes, financial panics — for causal identification. The 2008 financial crisis prompted renewed interest in historical analogues for crisis management.
