Q & A

What is the definition of investment in economics?

Investment refers to when firms spend money on capital goods to increase their productive capacity.

How do interest rates influence investment decisions?

Low interest rates decrease borrowing costs, encouraging firms to invest, while high interest rates discourage investment by making borrowing more expensive.

What is business confidence and why is it important for investment?

Business confidence is determined by firms' expectations of future profits and demand. High confidence leads to increased investment, while low confidence results in decreased investment.

What role does corporation tax play in investment levels?

Lower corporation tax increases retained profits, providing businesses with more resources to invest, whereas higher taxes reduce retained profits and investment capacity.

How does spare capacity affect a firm's willingness to invest?

If firms have high spare capacity, they have less incentive to invest, as they can utilize existing resources. Conversely, low spare capacity encourages investment to meet demand.

In what ways does competition impact investment?

Strong competition motivates firms to invest in technology and capital to keep pace with or surpass rivals, driving innovation and capacity enhancement.

How does the price of capital machinery affect investment decisions?

Lower prices for capital machinery reduce the cost of investment, encouraging firms to invest more due to the lower financial burden.

What is the accelerator effect in relation to investment?

The accelerator effect occurs when an increase in real GDP encourages further investment, creating a cycle where rising economic activity stimulates more investment.

Why is the concept of the hurdle important in investment decisions?

The hurdle is the required rate of return for investment projects. Lower interest rates make it easier for firms to meet this hurdle, incentivizing investment.

What are the two main ways firms finance their investments?

Firms finance investments primarily through borrowing money or using retained profits.
