Conflicting Signals for Aggregate Investment

Analyzing Aggregate Investment Amidst Economic Shifts

Suppose that due to a shift in monetary policy, the prevailing interest rate for business loans increases. At the same time, a wave of technological innovation leads firms to expect significantly higher future revenues from new capital projects. Considering the decision-making process of individual firms when evaluating the profitability of these projects, what is the most likely overall effect on the total level of investment in the economy?

The Microfoundations of Aggregate Investment

An economic analyst states: 'A decrease in the economy-wide interest rate will always lead to an increase in the total level of investment, because it makes borrowing cheaper for all firms.' Is this statement correct?

Match each macroeconomic change to its most likely direct consequence on firms' investment decisions and the resulting impact on aggregate investment, assuming all other factors remain constant.

Consider an economy with three available investment projects, detailed below. If the prevailing interest rate is 10%, what will be the total level of aggregate investment based on the present value criterion?
