This compelling research review touches on the contemporary debates in macroeconomics that have consequentially emerged as a result of government debt.

Or is high public debt bad for private sector confidence and growth, by feeding uncertainty, expectation of future tax hikes and an imminent collapse in the wake of the next crisis? This review presents a collection of articles reflecting on these complex and intriguing topics. This review will be useful for policy makers and academics alike, while being particularly suited for those wishing to explore this exciting research area further.
