Formula for Decomposing GDP Growth by Expenditure Component
US GDP Growth Component Contributions During the 2009 Recession (Example)
An economic analyst observes two sectors in a country's economy. The technology sector, which constitutes 5% of the total economy, is growing at 10% per year. The manufacturing sector, which constitutes 40% of the total economy, is growing at 2% per year. Based on this information, which statement provides the most accurate analysis of each sector's contribution to the country's overall economic growth?
Sectoral Contribution to Economic Growth
A sector of the economy that is growing at 10% will always contribute more to overall economic growth than a sector growing at 3%.

Analyzing GDP Component Contributions in a Recession
In the economic downturn of 2009, real GDP in the United States contracted significantly. Given that a component's contribution to GDP growth depends on both its own growth rate and its share of the economy, which of the following statements provides the most accurate analysis of this period?
Evaluating Component Impact on GDP during the 2009 Recession
True or False: During the sharp economic downturn in the US in 2009, the negative contribution of private investment to real GDP growth was greater than the negative contribution from personal consumption, primarily because the percentage drop in investment was far more severe than the percentage drop in consumption.
Match each major expenditure component of the economy with its characteristic behavior and contribution to the change in overall economic output during the sharp US downturn of 2009.
Deconstructing the 2009 US Economic Contraction
Analyzing Component Contributions to GDP Contraction
During the 2009 US recession, although personal consumption represents a much larger share of the total economy than private investment, the component that made the largest negative contribution to the change in overall economic output was ____.
An economy is composed of several expenditure components. During a recent downturn, two of these components behaved as follows:
- Component X, which constitutes 65% of the total economy, contracted by 3%.
- Component Y, which constitutes 15% of the total economy, contracted by 15%.
Based on this information, which statement provides the most accurate analysis of their respective contributions to the change in overall economic output?
During the severe economic downturn in the US in 2009, an analysis of the change in total economic output revealed that the decline in private investment (e.g., business spending on equipment and structures) contributed more to the overall contraction than the decline in personal consumption, despite consumption being a much larger part of the economy. This was because the percentage drop in investment was exceptionally large. Given this specific diagnosis of the problem, which of the following policy responses would have been the most targeted and direct approach to counteracting the primary driver of the economic decline?
