What happens if gdp decreases

Measuring GDP is a bit complicated but the calculation can be done in one of two ways—by adding up what everyone earned in a year, or by adding up what everyone spent. Both measures should arrive at about the same total. The income method is arrived at by adding up total compensation to employees, gross profits for incorporated and non incorporated firms, and taxes less any subsidies from the government. The expenditure method, which is more commonly used by the BEA, is calculated by adding total consumption, investment, government spending and net exports.

But it is an important distinction because this is why some GDP reports get revised. Nominal GDP measures the value of output during a given quarter or year using the prices of that time period. But the general level of prices can rise due to inflation, leading to an increase in nominal GDP even if the volume of goods and services produced is unchanged. However, the nominal GDP figures won't reflect the increase in prices. This is where real GDP comes in. The BEA will go back to a quarter or yearly period and measure the value of goods and services adjusted for inflation.

This is real GDP. An increase in GDP will raise the demand for money because people will need more money to make the transactions necessary to purchase the new GDP. In other words, real money demand rises due to the transactions demand effect.

This means that real money demand exceeds real money supply and the current interest rate is lower than the equilibrium rate. The final equilibrium will occur at point B on the diagram. Thus an increase in real GDP i. In contrast, a decrease in real GDP a recession will cause a decrease in average interest rates in an economy.

Jeopardy Questions. Our analysis challenges that view. The second chart shows the relationship between the year-to-year percentage-point changes in the unemployment rate and in the employment-to-population ratio.

The open circles in both panels show the historical relationship between these two variables from January to the peak that occurred one month before the start of the Great Recession. The solid circles show the relationship between the data during the recession left panel and since the recovery started in July right panel. The blue lines represent the historical relationship, while the red lines represent that relationship estimated for the Great Recession left panel and recovery right panel.

The left panel of the second chart shows that the relationship between the increase in the unemployment rate and the decline in the employment-to-population ratio during the recent recession is in line with the historical pattern.

Thus, while changes in GDP were not useful for predicting changes in unemployment during the recent recession, changes in the employment-to-population ratio were—unemployment during the Great Recession increased significantly because the ratio decreased proportionally. The right panel of the second chart shows a different story for the recovery, however. In particular, during the recovery the relationship between changes in the unemployment rate and the employment-to-population ratio shifted away from the historical pattern.

The same increase in the ratio experienced during the recent recession now corresponds to a larger drop in the unemployment rate. The historical relationship implies that if the employment-to-population ratio is constant, the unemployment rate will be roughly constant. The relationship estimated for the recovery implies that the unemployment rate drops by 1 percentage point even when the ratio remains constant.

Thus, compared with the historical experience, changes in the employment-to-population ratio alone do not explain the significant decline in the unemployment rate during the recent recovery. Our analysis suggests that in recent years there have been changes in the relationship between i GDP growth and changes in the unemployment rate and ii changes in the employment-to-population ratio and changes in the unemployment rate.
