Can consumption taxes stabilize the economy in the presence of consumption externalities?

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review


We discuss the stabilization role of consumption taxes under a balanced-budget rule in the presence of consumption externalities of the “keeping up with the Joneses” type. We consider a finance constrained economy and depart from a situation where sufficiently strong externalities make the steady state indeterminate, if government intervention is absent. Sufficiently procyclical consumption tax rates are able to ensure local saddle path stability. However, this procyclicality leads to the appearance of another steady state with lower levels of output which is a source or indeterminate. Therefore, government intervention with stabilization purposes may not be successful.
