This paper examines the macroeconomic effects of tax changes during fiscal consolidations. We
build a new narrative dataset of tax changes during fiscal consolidation years, containing detailed
information on the expected revenue impact, motivation, and announcement and
implementation dates of nearly 2,500 tax measures across 10 OECD countries. We analyze the
macroeconomic impact of tax changes, distinguishing between tax rate and tax base changes,
and further separating between changes in personal income, corporate income, and value added
tax. Our results suggest that base broadening during fiscal consolidations leads to smaller output
and employment declines compared to rate hikes, even when distinguishing between tax types.

Using a DSGE model calibrated to the euro area, we analyze the international effects of a fiscal devaluation (FD) implemented as a revenue-neutral shift from employer's social contributions to the Value Added Tax. We find that a FD in ‘Southern European countries’ has a strong positive effect on output, but mild effects on the trade balance and the real exchange rate. Since the benefits of a FD are small relative to the divergence in competitiveness, it is best addressed through structural reforms.
