In this paper, we estimate government purchase multipliers for a large number of OECD countries, allowing these multipliers to vary smoothly according to the state of the economy and using real-time forecast data to purge policy innovations of their predictable components. We adapt our previous...

A key issue in current research and policy is the size of fiscal multipliers when the economy is in recession. We provide three insights. First, using regime-switching models, we find large differences in the size of spending multipliers in recessions and expansions with fiscal policy being...

While theoretical models consistently predict that government spending shocks should lead to appreciation of the domestic currency, empirical studies have been stubbornly finding depreciation. Using daily data on U.S. defense spending (announced and actual payments), we document that the dollar...
