This paper is concerned with delineating conditions under which public financial policies have no real and/or price effects. In the absence of intergenerational distribution effects, public financial policy is irrelevant:an increase in government debt (whether indexed or not), an exchange of...

We study the effects of debt-financed fiscal transfers in a general equilibrium, heterogeneous-agent model of the world economy. In the long run, increases in government debt anywhere raise the world interest rate and increase private wealth everywhere. In the short run, a country with a...

This paper presents a framework for analyzing how bounded rationality affects monetary and fiscal policy. The model is a tractable and parsimonious enrichment of the widely-used New Keynesian model – with one main new “cognitive discounting” parameter, which quantifies how poorly agents...

Behavioral economics is changing our understanding of how economic policy operates, including tax policy. In this paper, we consider some implications of behavioral economics for tax policy, such as how it changes our understanding of the welfare consequences of taxation, the relative...

This essay aims to explain the nature of monetary and fiscal policy interactions and how those interactions could inform the fiscal rules that countries choose to follow. It makes two points: (1) monetary policy control of inflation requires appropriate fiscal backing; (2) European fiscal...

We study the Ramsey policy problem in an economy in which public debt contributes to the supply of assets that private agents can use as buffer stock and collateral, or as a vehicle of liquidity. Issuing more debt eases the underlying financial friction. This raises welfare by improving the...

In this paper, we develop a new model for government cost-benefit analysis in the presence of risk. In our model, a benevolent government chooses the scale of a risky project in the presence of two key frictions. First, there are market failures, which cause the government to perceive project...

We study optimal monetary and fiscal policy in a model with heterogeneous agents, incomplete markets, and nominal rigidities. We develop numerical techniques to approximate Ramsey plans and apply them to a calibrated economy to compute optimal responses of nominal interest rates and labor tax...
