Abstract:
Research on links between the level of a country’s public debt and its broader economic developments has been heatedly debated in the economic literature. Two strands of the research stand out — one linking the level of debt to a country’s GDP growth rate and the other examining the debt level as an EWI of economic crises. As a broad generalization, research at the moment favors the view that high levels of debt are not a cause, in and of themselves, of low growth nor are they particularly good predictors of impending economic or even debt crises. In principle, the empirical findings have obvious implications for policy makers confronting the question of how to fashion policies (and fiscal policy in particular) when a country has a high debt burden. The IMF, as both a contributor to the literature and an adviser concerned with preventing or dealing with debt crises, has a particularly important stake in navigating the findings. Whether in its surveillance (routine annual advice to all member countries) or the construction of its lending programs to support countries in or near crisis, the IMF must answer the question “how much does the level of debt matter?” Despite the empirical research that casts doubt on the importance of debt, the level of debt figures prominently in the algebra of debt sustainability and the IMF’s real world policy advice. This policy brief examines the nexus of the relatively strong conclusions coming from the academic research and the IMF’s policy advice. It addresses the following question: given that the broad conclusion from the academic literature is that the level of debt itself is not systematically bad for growth or stability, why does the debt level seem to figure rather prominently in the IMF’s policy advice and conditionality?

2. On the Desirability of Nominal GDP Targeting

Author:

Abstract:
This paper evaluates the welfare properties of nominal GDP targeting in the context of a New Keynesian model with both price and wage rigidity. In particular, we compare nominal GDP targeting to inflation and output gap targeting as well as to a conventional Taylor rule. These comparisons are made on the basis of welfare losses relative to a hypothetical equilibrium with flexible prices and wages. Output gap targeting is the most desirable of the rules under consideration, but nominal GDP targeting performs almost as well. Nominal GDP targeting is associated with smaller welfare losses than a Taylor rule and significantly outperforms inflation targeting. Relative to inflation targeting and a Taylor rule, nominal GDP targeting performs best conditional on supply shocks and when wages are sticky relative to prices. Nominal GDP targeting may outperform output gap targeting if the gap is observed with noise, and has more desirable properties related to equilibrium determinacy than does gap targeting.

3. Inflation and Activity: Two Explorations and Their Monetary Policy Implications

Working Paper
Institution:
Peterson Institute for International Economics
Abstract:
Blanchard, Cerutti, and Summers explore two issues triggered by the global financial crisis. First, in most advanced countries, output remains far below the prerecession trend, suggesting hysteresis. The authors look at 122 recessions over the past 50 years in 23 countries and find that a high proportion of them have been followed by lower output or even lower growth. Second, while inflation has decreased, it has decreased less than anticipated, suggesting a breakdown of the relation between inflation and activity. The authors estimate a Phillips curve relation over the past 50 years for 20 countries and find that the effect of unemployment on inflation, for given expected inflation, decreased until the early 1990s but has remained roughly stable since then. The paper concludes with implications for monetary policy.

4. Further Statistical Debate on "Too Much Finance"

Author:
William R. Cline
Publication Date:

Content Type:
Working Paper
Institution:
Peterson Institute for International Economics
Abstract:
Cline critiques OECD findings on "too much finance," which seem to imply that the optimal amount of credit in an economy is zero, given the linear specification of the main tests. If these results were taken literally, there would be a radical policy implication: Growth would be maximized by completely eliminating credit finance. He then finds that the negative impact of additional finance on growth is reversed when the appropriate (purchasing-power-parity) per capita income is applied and country fixed effects are removed. Separate tests for countries with intermediated finance below and above 60 percent of GDP show a significant positive effect of finance on growth in the lower group but an insignificant effect in the higher group. He also responds to critics of his earlier study.
