During and in the aftermath of the financial crisis of $2007-2009,$ planned investment fell substantially, despite significant decreases in the real interest rate. What factors related to the planned investment function could explain this?

Key Concepts

Uncertainty and Risk Premium

High levels of economic and financial uncertainty increase the risk premium that investors require. When uncertainty rises, even nominally low rates can be accompanied by hidden risks that deter investment. The increased cost of capital, in a risk-adjusted sense, leads firms to postpone or reduce planned expenditures despite falling real interest rates.

Financial Constraints and Credit Conditions

During financial crises, disruptions in credit markets can impose additional constraints on firms. Even with lower real interest rates, tighter lending standards, reduced access to financing, and higher perceived risks in the banking sector can make it difficult for firms to secure the funds needed for new investments.

Planned Investment Function

This concept models the relationship between the level of investment a firm plans to undertake and factors such as the real interest rate and expected returns on capital. It acknowledges that while lower interest rates generally make borrowing and investing more attractive, other factors can significantly influence investment decisions.

Marginal Efficiency of Capital

This is the expected rate of return on an additional unit of capital invested. In times of economic uncertainty, even if borrowing costs are low, the anticipated returns from investing in new projects may fall if future profitability is in question, leading firms to cut back on planned investment.

Business Confidence and Expected Returns

Firms' expectations about future economic conditions, profitability, and demand play a key role in investment decisions. During periods of crisis, diminished business confidence and pessimistic projections about future market conditions can reduce the expected returns from investment, thereby offsetting the stimulative effect of lower interest rates.
