Fundamentally, for New Zealand, there appears to be no reason for any change to fiscal policy to help deal with the slowdown – something we have discussed here.
Show me the actual “market failure” – then we can figure out how the government can improve outcomes. If there is no market failure, then government action to “stabilise” the economy will simply make matters worse.
Note: This is different to government actions to try and help cushion the impact of a sharp change in fundamental economic conditions. Although a change in the economic situation may change the optimal allocation of resources, a labour market that allows people to upskill and gives them firm institutions to rely on in the bad times will help to reduce the welfare cost associated with the change. This is subtly, but importantly, different from a simple “fiscal expansion”.
