The empirical relationship between government spending and private inv
estment is examined, using a panel of 14 OECD co countries The evidenc
e suggests the existence of a significant crowding-in effect of privat
e investment by public investment, through the positive impact of infr
astructure on private investment productivity. Moreover, government co
nsumption appears to crowd out private investment. The implications of
these results are of foremost importance when it comes to fiscal cons
olidation. Deficit reductions engineered through cuts in public invest
ment could severely impinge on private capital accumulation and growth
prospects.
