Single-equation estimates of fiscal reaction functions, which relate primary surpluses to past debt-GDP ratios and control variables, are subject to potentially serious simultaneity bias that can produce misleading inferences about fiscal behavior. Biases arise from failure to model the general...

Aging populations in advanced economies are placing ever-increasing demands on government spending in the form of old-age benefits. Economies that have promised substantially more benefits than they have made provision to finance are heading into a prolonged era of fiscal stress. Unresolved...

We study cointegrating relationships among fiscal variables and output and use them to introduce a new measure of the government's fiscal position. In the US since World War II, we find that the primary surplus-GDP ratio and the government debt-GDP ratio are nonstationary, which invalidates...

This paper surveys the recent literature on the theory of macroeconomic policy. We study the effect of various incentive constraints on the policy making process, such as lack of credibility, political opportunism, political ideology, and divided government. The survey is organized in three...

The European Central Bank is unique in setting monetary policy for several sovereign states with heterogeneous debt levels and different maturity structures. The monetary-fiscal nexus is central to the functioning of the euro area. We focus on one particular aspect of that nexus, the effect the...

Why did the country that borrowed the most industrialize first? Earlier research has viewed the explosion of debt in 18th century Britain as either detrimental, or as neutral for economic growth. In this paper, we argue instead that Britain's borrowing boom was beneficial. The massive issuance...

Governments around the world have gone on a massive fiscal expansion in response to the Covid crisis, increasing government debt to levels not seen in 75 years. How will this debt be repaid? What role do conventional and unconventional monetary policy play? We investigate debt sustainability in...

An earlier paper by the author investigated the quantitative implications, for the effectiveness of fiscal and monetary policies, of a model treating the determination of long-term interest rates by explicitly imposing the market clearing equilibrium condition that the quantity of bonds issued...

The setup of the paper is as follows: Section I presents a fairly standard, small deterministic macromodel with a number of classical features. All markets clear instantaneously, there is no money illusion, and perfect foresight rules. The effects of monetary, financial, and fiscal policies in...
