what is gross investment

how does rate of economic growh effect investment
Rate of economic growth as businesses would be more confident about their investments and the
higher demand would lead to a higher return rate on the investment
how does ‘animal spirits’ effect investment
businesses are confident about the future and expect future growth, investment will increase as they want to prepare for the future. If they are fearful of the future, then they will not invest money in new ideas or machinery as it may fail
how does demand for exports effect investment
If the world economy is booming, demand for exports is likely to increase and therefore exporting firms’ investment is likely to increase to cope with this extra demand. This will have a knock-on effect and encourage other firms to increase their investment
how does interest rates effect investment
Most investment is done through borrowing. High interest rates mean that borrowing is more expensive, so a business needs to be more confident of good profits in order to cover the extra costs of borrowing
