What are components of gdp
Unit 6 - Components of GDP - Final Goods ApproachThe consumption of goods and services falls under one of the following categories:
- Durable goods - The consumption of durable goods is considered similar to a consumer investment. Durable goods are purchased with the intention of keeping them for a sustained duration of time. Examples of durable consumer purchases include washing machines, refrigerators, automobiles, and toaster ovens.
- Business Investment - This includes the actual purchases of goods used in the production process. Business investment includes the construction of new offices and factories, and the purchase of machinery, computers, and any other equipment used to assist labor in the production of goods and services.
Business investment counts as gross investment, which includes purchases of machinery to replace worn-out equipment. If a firm replaces one machine with another that does not increase output, then nothing is added to the nation's economy. To correct for this, net investment can be used, which subtracts out depreciation of existing capital from the gross (total) business investment made by firms.
Although inventories are a relatively small portion of the overall investment sector, inventories are a critical component of changes in GDP over the business cycle. If the economy is slowing down, possibly entering a recession, the bearer of the bad news will often be an undesired accumulation of inventories. As consumers reduce their purchases, sales of goods and services slow, inventories build up, and firms slash production (laying off employees) to reduce unwanted (and costly) inventories.
inventories. We will look at the economy as a whole.
- The economic impact of an undesired accumulation or increase in business inventories. Businesses plan ahead and forecast future sales. Based on their expectations, they stockpile inventories of goods the expect to sell in the near future. The reason is simple. Businesses want the goods available to meet customer demands or else they will lose the sale, and most likely lose it to a competitor. If there is a slowdown in consumption in many economic sectors, then many businesses will not sell as many goods as they had planned to. As a result, businesses will not sell off their inventories of goods as they had planned and inventories will accumulate.
When inventories accumulate due to a decrease in consumption, businesses respond by reducing orders of goods from producers. In turn, as producers face a cutback in demand for their goods, they will decrease output. When inventories are accumulating in many sectors of the economy, reductions in the production of goods becomes widespread, and as firms reduce their output, many workers are laid off. As payrolls are reduced, the number of unemployed swells and the unemployment rate rises. With the reduction in output, GDP growth falls and if the drop in production is sharp enough, the economy goes into a recession.
The surge in demand for goods and services as well as the responding hike in production and employment comes at a possible cost. As more jobs are created, incomes rise, further contributing to an increase in the demand for goods and services. The potential result is a rise in the inflation rate due to demand-pull effects. Demand-pull inflation results from price pressures caused by rising demand for a good. In addition, cost-push pressures may also lead to greater inflation. As firms increase their output and demand for labor, wages may rise, especially if the economy was already near or at full-employment. Higher wages increase production costs that may be passed on to the consumer in the form of higher prices for goods.
The important point made here is that although inventories are a relatively minor component of GDP, rapid changes from their desired levels can have important economic consequences. When inventories accumulate beyond desired levels, an economic slowdown may be on the horizon as producers reduce their output. Or if inventories are rapidly being depleted, then economic growth and possibly inflation may soon rise as wage and price pressures build. Economic analysts monitor the divergence of inventories from desired levels as a leading indicator of potential changes in future economic growth rates.
The government sector tracks what the government actually spends money on. Government purchases of goods and services include stealth bombers, government-funded research, space shuttles, salaries, and toasters. Many of these items are seldom sold in markets; as a result, they are valued at the price the government pays for them. The calculation of government spending for GDP purposes excludes several tremendous categories of actual spending: transfer payments, which redistribute income primarily to individuals who are potential consumers, and interest payments on the debt.Source: www.colorado.edu
