According to the so-called expectations channel, a fiscal consolidation may give rise to less contractionary, or even expansionary effects on consumption despite the decline in current disposable income. We propose a design for a laboratory experiment to study the conditions under which the expectations channel operates. We find that unsustainable fiscal conditions prior to a consolidation render the consolidation less contractionary as subjects sustain consumption to a greater extent through accumulated savings, which provides support for the expectations channel. We also find, however, that subjects are generally reluctant to reduce savings distinctly after the consolidation unless the consolidation is accompanied by a credible commitment of the fiscal authority to abstain from additional tax hikes. Overall our results suggest that the conditions, under which the expectations channel operates, are rather restrictive.
