The Italian government has decided to pursue an expansionary fiscal policy, with increased welfare spending as its focus. This column uses evidence from the 2010-2012 sovereign debt crisis to explore the potential negative effects of this policy on private investment. It finds that an increase in a bank’s credit default swap spreads leads to lower investment and employment for younger and smaller firms and in the aggregate. These findings suggest the planned fiscal expansion could substantially crowd out private investment.

Housing bubbles may crowd out credit from other sectors, but they may also have a crowding-in effect by providing collateral to real estate-owning firms or generating attractive assets which banks can securitise and use to increase their credit supply. This column applies data from the Spanish housing bubble to a simple model of a closed economy to show that both effects were present. At first, the crowding-out effect dominated, but then crowding in occurred. This model can be applied to similar positive shocks in other sectors.

High levels of public debt are correlated with lower economic growth across countries, but questions remain about whether this relationship is causal. Using Chinese data, this column explores whether increasing public debt crowds out private investment. City-level investment ratios are found to be negatively correlated with local government debt for private manufacturing firms, but not for state-owned or foreign-owned manufacturers. This suggests that as well as the short-term benefits of fiscal stimulus, there might also be negative longer-term effects, such as the crowding out of more efficient firms.
