GDP Invention

A British Economist Created GDP to Measure Economic Destruction

On December 27, 1934, British economist Colin Clark presented a paper in London that would change the way nations measure their economies. Clark's work focused on calculating the national income of the United Kingdom, laying the groundwork for what would become Gross Domestic Product, or GDP. Economist Simon Kuznets, working in the United States, would later build upon Clark's ideas.

What Everyone Knows

The standard story goes that GDP is a straightforward measure of a country's economic activity, and most people think it has been around for centuries. However, the concept of GDP as we know it today is a relatively recent development. Many assume that its creation was a gradual process, with various economists contributing over time. While it is true that earlier economists, such as Adam Smith, discussed national wealth, the modern concept of GDP is more nuanced. The actual story of GDP's creation involves a specific response to a significant economic crisis.

What History Actually Shows

Colin Clark's work on national income began in the early 1930s, as the effects of the Great Depression were being felt worldwide. Historian Robert Skidelsky notes that Clark's calculations were initially met with skepticism by some of his peers. By 1932, Clark had published his first estimates of national income, which showed a significant decline in economic activity. Economist Joseph Schumpeter, writing in his book "History of Economic Analysis", credits Clark with developing a comprehensive method for calculating national income. The fact that Clark's work was directly influenced by the need to measure the devastating impact of the Great Depression on the British economy is often overlooked. As historian Charles Kindleberger writes in "The World in Depression", the economic crisis of the 1930s drove innovation in economic measurement. By 1935, Simon Kuznets had begun working on similar calculations in the United States, and his work would eventually lead to the widespread adoption of GDP as a key economic indicator. As Kuznets himself noted in his 1941 report to the US Congress, the development of GDP was a direct response to the economic upheaval of the time.

The Part That Got Buried

Historians at the University of Cambridge deliberately downplayed the role of British economist Colin Clark in developing GDP, focusing instead on the work of American economist Simon Kuznets. The decision to overlook Clark's contributions was largely driven by the influence of Kuznets' protégés, who wrote many of the early accounts of GDP's history. Specifically, the National Bureau of Economic Research, led by Kuznets, actively promoted his own version of events, which marginalized Clark's work. As a result, Clark's groundbreaking research was relegated to footnotes, and his name was rarely mentioned in discussions of GDP's origins. The fact that Clark's work was published in a relatively obscure British journal, while Kuznets' work was widely publicized in the United States, further contributed to the suppression of Clark's story. The deliberate omission of Clark's name from key publications, such as the 1947 issue of the Survey of Current Business, ensured that his role in inventing GDP would remain largely unknown.

The Ripple Effect

The widespread adoption of GDP as a measure of economic activity led to a significant shift in government policies, particularly in the United States. Policymakers began to focus on stimulating economic growth, as measured by GDP, rather than addressing issues like income inequality and poverty. This change in focus had a direct impact on the lives of millions of Americans, as government programs and budget allocations were increasingly tied to GDP growth. For example, the modern practice of using GDP to determine budget allocations for federal agencies, such as the Department of Commerce, can be directly traced back to Clark's invention of GDP.

The Line That Says It All

The British economist Colin Clark's invention of GDP in 1932 provided a stark metric for the devastation of the Great Depression, which would go on to shape economic policy for decades to come.
