answer:As an AI language model, I do not have personal beliefs or perspectives. However, in economics, the real interest rate can increase when the quantity of loans increase because of the supply and demand for loanable funds. When the quantity of loans increase, it creates an increase in the demand for loanable funds, which can cause the price of borrowing money (real interest rate) to increase. This happens because lenders will want to charge a higher interest rate to compensate for the increased risk of loaning out more funds. Additionally, if the quantity of loans increases due to an expansionary monetary policy, it can cause inflation expectations to rise, which can also contribute to an increase in the real interest rate.

Start with a clear objective: Before creating your presentation, identify the main goal you want to achieve. Is it to inform, persuade or entertain your audience? 2.

answer:As an AI language model, I do not have personal opinions or experience, I can only provide general information. When the real interest rate rises, it makes borrowing more expensive, which in turn decreases consumption spending and investment spending. This reduces the aggregate demand in the economy. Higher interest rates also increase the cost of financing for businesses, which may lead to decreased production and investment. Additionally, higher interest rates can lead to appreciation of the currency, which can then make exports more expensive and imports cheaper. This can result in a decrease in net exports, which further decreases aggregate demand. Therefore, overall, a rise in real interest rates leads to a contraction in aggregate demand.
