"Big G" typically refers to aggregate government spending on a homogeneous good. In this paper, we open up this construct by analyzing the entire universe of procurement contracts of the US government and establish five facts. First, government spending is granular, that is, it is concentrated...

Implementation lags are one of policymakers' concerns about fiscal policies, as these may reduce their efficacy. Using a standard New Keynesian model with an effective lower bound on the nominal interest rate, we compare the impacts of fiscal stimulus on output across various lengths of...

The presence of the lagged shadow policy rate in the interest rate feedback rule reduces the government spending multiplier nontrivially when the policy rate is constrained at the zero lower bound (ZLB). In the economy with policy inertia, increased inflation and output due to higher government...

This paper assesses the transmission of fiscal policy shocks in a New Keynesian framework where government expenditures contribute to aggregate production. It is shown that even if the impact of government expenditures on production is small, this assumption helps to reconcile the models'...

The jointly optimal monetary and fiscal policy mix in a multi-sector New Keynesian model with sectoral government spending and productivity shocks entails a separation of roles: Sectoral government spending optimally adjusts to sectoral output gaps and inflation rates---a policy supported by...

This paper studies the main channels through which interest rate normalization has fiscalimplications in the United States. While unexpected inflation reduces the real value ofgovernment liabilities, a rising policy rate increases government financing needs because ofhigher interest payments and...

Over the last few decades, real interest rates have trended downward in many countries. The most common explanation is that this reflects depressed demand due to demographic, technological and other real factors such as income inequality. In this paper we explore the claim that these trends may...

This study revisits and tests empirically the Portfolio Theory of Inflation (PTI), which analyzes how the effectiveness of macroeconomic policy in open and globally financially integrated economies is influenced by global investor decisions (Bossone, The portfolio theory of inflation and policy...

We provide an introduction to optimal fiscal and monetary policy using the primal approach to optimal taxation. We use this approach to address how fiscal and monetary policy should be set over the long run and over the business cycle. We find four substantive lessons for policymaking: Capital...

President Biden signed a $1.9 trillion COVID relief package (the “American Rescue Plan”) on March 11, 2021. Without a corresponding increase in taxes, this plan has set off alarm bells for those concerned about the expansion of government deficits and debt. Mainstream economists have raised...
