GDP has been relied upon at every turn by the coalition government to demonstrate the credibility of its ‘long-term economic plan’. Ahead of the general election, LSE alumnus Philipp Lepenies will question how GDP came to be indispensable as the indicator for progress, and demonstrate why any attempt to reduce the impact of this figure on policy needs to start by understanding how it came to occupy the throne in the first place.

About the event

GDP is the most powerful statistical figure in human history. It is much more than a simple measure of the value of the produced goods and services of a country. It is the main indicator for progress, well-being, power and development. Any problem that modern governments attempt to solve – from climate change to economic crises – revert to an approach that revolves around GDP.

But why is this so? How could a statistical figure that was completely unknown before World War II triumph in such a fashion? Philipp Lepenies tackles these questions in his presentation of the political history of GDP, showing how it became universally indispensable for politics and politicians.

It’s a topic that now has extra prominence given the role that GDP and growth still play in development discourse. Various international initiatives on an unprecedented historical scale are searching for alternative measurers of progress that are to “dethrone” GDP and lessen the degree to which it monopolizes politics.

Dr Lepenies contends that the first and most important step in this endeavour is to be conscious of how and why GDP came to sit so firmly in the saddle – and why earlier attempts to change this have been in vain.
