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 essay discusses the reasons for and implications of the decline in real interest rates around the world over the past several decades. It suggests that the decline in interest rates is largely explicable from trends in saving, growth, and markups. In this environment, greater government...

We develop a unified framework for optimally managing public portfolios for a class of macro-finance models that include widely-used specifications for households' risk and liquidity preferences, market structures for financial assets, and trading frictions. An optimal portfolio hedges...

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...

The fall in the U.S. public debt/GDP ratio from 106% in 1946 to 23% in 1974 is often attributed to high rates of economic growth. This paper examines the roles of three other factors: primary budget surpluses, surprise inflation, and pegged interest rates before the Fed-Treasury Accord of 1951....

In a deterministic overlapping-generations economy with production and physical capital, the price of debt can be positive without any budget surpluses being in the offing, because debt incorporates a rational bubble. Yet the dynamics of debt remain a function of the dynamics of the primary...

We consider public debt from a long-term historical perspective, showing how the purposes for which governments borrow have evolved over time. Periods when debt-to-GDP ratios rose explosively as a result of wars, depressions and financial crises also have a long history. Many of these episodes...

Over the past four decades, government debt as a fraction of GDP has been on an upward trajectory in advanced economies, approaching levels not reached since World War II. While normative macroeconomic theories can explain the increase in the level of debt in certain periods as a response to...

This paper makes two contributions. First, we examine the macroeconomic implications of Puerto Rico's Fiscal Plan that was certified in March 2017 for fiscal years 2017-18 to 2026-27. Second, we perform a Debt Sustainability Analysis (DSA) that incorporates the expected macroeconomic dynamics...

This note comments on two central issues for fiscal policy design in the UK, highlighted in the recent Code for Fiscal Stability' proposed by the new Labour government. The first concerns the merits of the so-called golden rule of public sector investment' -- the proposition that, over the...
