The Effect of Fiscal Rules on Public Investment If Budget Deficits are Politically Motivated

Uncertainty about the future preferences of the government may induce policy makers to run excessive budget deficits.

Rather, strategic manipulation shifts from public debt to public investment. As an alternative, we examine the effects of a capital borrowing rule which permits the government to run a budget deficit equal to the amount of public investment. We show that this rule effectively eliminates strategic behaviour
