We apply ideas from fiscal federalism to reassess how fiscal authority should be delegated within a monetary union. In a real-economy model with no fiscal externalities, in which local fiscal authorities have an informational advantage about the preferences of their citizens for public spending...

Reducing high public debts is key for countries seeking to restore fiscal capacity and resilience in the wake of recent crises. But large debt reductions are rare. Jamaica stands out for reducing its debt from 144 percent of GDP to 72 percent over the last decade, a record achieved by running...

An impulse response is the dynamic average effect of an intervention across horizons. We use the well-known Kitagawa-Blinder-Oaxaca decomposition to explore a response's heterogeneity over time and over states of the economy. This can be implemented with a simple extension to the usual local...

We develop an endogenous growth model with heterogeneous firms facing financial frictions, where misallocation emerges explicitly as a crucial endogenous state variable and plays a significant role in driving economic growth through the valuation channel. The model illustrates that transient...

Fiscal policy in the U.S. and other countries renders intertemporal budgets non-differentiable, nonconvex, and discontinuous. Consequently, assessing work and saving responses to policy requires global optimization. This paper develops the Global Life-Cycle Optimizer (GLO), a stochastic...

A central question in applied research is to estimate the effect of an exogenous intervention or shock on an outcome. The intervention can affect the outcome and controls on impact and over time. Moreover, there can be subsequent feedback between outcomes, controls and the intervention. Many of...
