Measuring the effects of discretionary fiscal policy is both difficult and controversial, as some explicit or implicit identifying assumptions need to be made to isolate exogenous and unanticipated changes in taxes and government spending. Studies based on structural vector autoregressions...

We investigate the effects of fiscal policy surprises for US data, using vector autoregressions.We overcome the difficulties that changes in fiscal policy may manifest themselves in variables other than fiscal variables first and that fiscal variables may respond 'automatically' to business...

We develop a Fiscal Frontier which traces out the maximum government debt level that can be sustained at a given welfare cost. Through duality, the intertemporal policy mix underpinning the Frontier mirrors standard Ramsey policy and defines an upper limit on the welfare gains that can be...

We develop a closed economy model to study the interactions among sovereign risk premia, fiscal limits, and fiscal policy. The stochastic fiscal limits, which measure the ability and willingness of the government to service its debt, arise endogenously from a dynamic Laffer curve. The...

We develop a closed economy model in order to study the interactions among sovereign risk premia, fiscal limits and fiscal policy. Default risk premia reflect the market's expectations about the ability and willingness of the government to service its debt. The government's ability arises...

This study uses simulations of state-dependent distributions of fiscal limits for 18 economies in Central America and the Caribbean to better understand governments' ability to service their debt, arising from endogenously determined dynamic Laffer curves. Using a small, open economy model to...

We develop a closed economy model in order to study the interactions among sovereign risk premia, fiscal limits and fiscal policy. The stochastic fiscal limit, which measures the ability and willingness of the government to service its debt, arises endogenously from dynamic Laffer Curves. The...

Using the Reinhart-Rogoff dataset, we find a debt threshold not around 90 percent but around 30 percent above which the median real GDP growth falls abruptly. Our work is the first to formally test for threshold effects in the relationship between public debt and median real GDP growth. The null...
