Cause-and-effect chain

Question

Mark out the cause-and-effect chain through which refinancing and financing of the public debt might influence real interest rates, the stock of capital, private investment and economic development. How might investment in public capital & complementarities among public & private capital alter the outcome of the cause-effect chain?

Answer 1

Cause and effect chain:  Government borrowing to finance the debt competes along with private borrowing & drives up the interest rate; the higher interest rate causes a decline in private capital and economic growth slowdown.

Though, if public investment complements private investment, private borrowers might be ready to pay higher rates for positive growth chance.  Productivity and economic growth could increase.
