Summary Using state‐dependent local projections and historical US data, we find that government spending multipliers are considerably larger in periods of private debt overhang. In particular, while multipliers are below or close to one in low private debt states, we find significant crowding‐in of private spending in periods of debt overhang, resulting in multipliers that are much larger than one. In high private debt episodes, more government purchases even reduce the ratio of government debt to gross domestic product. These results are robust for the type of shocks, and when we control for the business cycle, financial crises, deleveraging episodes, government debt overhang, and the zero‐lower‐bound.

Using a dataset covering a large sample of emerging economies (EMEs), we study the relationship between debt and economic performance in bad times. While previous research has shown that private debt buildups exacerbate the duration and intensity of recessions in advanced economies (AEs), we document that this effect is very pronounced in EMEs as well. Moreover, although rapid public debt buildups are unlikely to be the primary trigger of financial crises, in EMEs they are associated with deeper and longer recessions than in AEs.

We use a novel quarterly dataset of U.S. states to examine the dynamics and determinants of relative government spending multipliers in the decade surrounding the Great Recession. We find average multipliers that are similar to those that have been reported for the decades preceding the crisis, but this masks substantial heterogeneity.First, average cumulative multipliers were around 2 in the impact quarter, but declined to less than 1 after one year. Second, implied relative multipliers ranged between 0 and more than 4 across states at particular points in time, as well as for the same state at different moments within the sample period depending on the individual state's stance of the business cycle, household indebtedness and the interaction of both conditions. Finally, we provide evidence that, controlling for total expenditures, a mere redistribution of government spending across states did also had a significant influence on the aggregate U.S. economy due to cross-state heterogeneity of the effects.JEL classification: C23, E32, E44, E62

We use novel quarterly data of U.S. states to examine the dynamics of relative spending multipliers in the decade surrounding the Great Recession. While multipliers were around 1 in expansions, they reached values above 4 when a state was in a recession. Also a high (low) degree of household indebtedness augmented (lowered) a state's multiplier by 0.5 in expansions and 2 in recessions. We further document modest positive spillover effects across states and show that a mere redistribution of spending across states also had a significant influence on the aggregate U.S. economy due to cross-state heterogeneity of the effects.
