EC203 focuses on the economic history of economic growth and technical change centred on the 'second industrial revolution' and stemming from the advances in the latter part of the 19th century. Beginning with an overview of global patterns of growth to the early 21st century, EC203 introduces macroeconomic approaches to long-run growth, in particular accounting for technological change. It continues with case studies of key sectors contributing to technical progress, including electricity, chemicals, in the late 19th century through to Information and Communications Technology in the late 20th and early 21st centuries.
