CEVAP:

Autonomous investments refer to the level of investment expenditures which is determined independent of income. When examining the determination of national
income in an economy, we will assume that the investments are autonomous to simplify the analysis, i.e. independent of the current income level. However, this does not mean that we assume that investments are fixed at a certain level. There are a number of factors that cause investment spending to change. We assume that GDP is not one of these factors. In this case, we can draw autonomous investment expenditures parallel to the horizontal axis. This means that if the income increases or decreases, the autonomous investment expenditures will not be affected.
