In this paper we quantitatively characterize the optimal capital and labor income tax in an overlapping generations model with idiosyncratic, uninsurable income shocks, where households also differ permanently with respect to their ability to generate income. The welfare criterion we employ is...

We explore the welfare consequences of different taxation schemes in an economy where agents are debt-constrained. If agents default on their debt, they are banned from future credit markets, but retain their private endowments which are subject to income taxation. A change in the tax system...

While high uncertainty is an inherent implication of the economy entering the zero lower bound, deflation is not, because agents are likely to be uncertain about the way policymakers will deal with the large stock of debt arising from a severe recession. We draw this conclusion based on a...

How much additional tax revenue can the government generate by increasing the level of labor income taxes? In this paper we argue that the degree of tax progressivity is a quantitatively important determinant of the answer to this question. To make this point we develop a large scale overlapping...

The Covid-19 pandemic found policymakers facing constraints on their ability to react to an exceptionally large negative shock. The current low interest rate environment limits the tools the central bank can use to stabilize the economy, while the large public debt curtails the efficacy of...

Fiscal announcements may transfer information about the government’s view of the macroeconomic outlook to the private sector, diminishing the effectiveness of fiscal policy as a stabilization tool. We construct a novel dataset that combines daily data on Japanese stock prices with narrative...

Low and stable inflation requires an appropriate fiscal framework aimed at stabilizing government debt. Historically, trend inflation is critically influenced by actual or perceived changes to this framework, while cost-push shocks only account for short-lasting movements in inflation. Before...

We develop a theoretical framework to account for the observed instability of the link between inflation and fiscal imbalances across time and countries. Current policy makers behavior influences agents ' beliefs about the way debt will be stabilized. The standard policy mix consists of a...

In this paper we characterize quantitativelya the optimal mix of progressive income taxes and education subsidies in a model with endogeneous himan capital formation, borrowing constraints, income risk and incomplete financial markets. Progressive labor income taxes provide social insurance...

We employ a new class of general equilibrium models with partially unfunded debt, as proposed in Bianchi et al. (2023), to study the relation between real interest rates and fiscal policy. Unfunded fiscal shocks generate a decline in real interest rates, while funded fiscal shocks cause an...
