Additionally, respondents may be more prone to round off or up due to social desirability. By ignoring the heaping process a severe bias...

This paper analyzes the effect of planned fiscal consolidation on GDP growth forecast errors from the years 2010–2013 using cross section analyses and fixed effects estimations. Our main findings are that fiscal multipliers have been underestimated in most instances for the year 2011 while we...
