This paper studies the long-run impact of public debt expansion on economic growth and investigates whether the debt-growth relation varies with the level of indebtedness. Our contribution is both theoretical and empirical. On the theoretical side, we develop tests for threshold effects in the context of dynamic heterogeneous panel data models with cross-sectionally dependent errors and illustrate, by means of Monte Carlo experiments, that they perform well in small samples. On the empirical side, using data on a sample of 40 countries (grouped into advanced and developing) over the 1965- 2010 period, we find no evidence for a universally applicable threshold effect in the relationship between public debt and economic growth, once we account for the impact of global factors and their spillover effects. Regardless of the threshold, however, we find significant negative long-run effects of public debt build-up on output growth. Provided that public debt is on a downward trajectory, a country with a high level of debt can grow just as fast as its peers in the long run.
Are the current account fluctuations in oil-exporting countries "excessive"? How should their real exchange rate respond to the evolution of external (and domestic) fundamentals? This paper proposes methodologies tailored to the specific features of oil-exporting countries that help address these questions. Price-based methodologies (based on the time series of real effective exchange rates) identify a strong link between the real exchange rate and the terms of trade, but have relatively limited explanatory power. On the other hand, an empirical model of the current account, which fits oil exporting countries' data well, and an intertemporal model that takes into account the stock of oil reserves provide useful benchmarks for oil exporters' external balances.
The assessment of external positions and exchange rates of member countries is a key mandate of the IMF. The External Balance Assessment (EBA) methodology has provided the framework for conducting external sector assessments by Fund staff since its introduction in 2012. This paper provides the latest version of the EBA methodology, updated in 2022 with additional refinements to the current account and real exchange rate regression models, as well as updated estimates for other components of the EBA methodology. The paper also includes an assessment of how estimated current account gaps based on EBA are associated with future external adjustment.
We study the long-run relationship between public debt and growth in a large panel of countries. Our analysis takes particular note of theoretical arguments and data considerations in modeling the debt-growth relationship as heterogeneous across countries. We investigate the issue of nonlinearities (debt thresholds) in both the cross-country and within-country dimensions, employing novel methods and diagnostics from the time-series literature adapted for use in the panel. We find some support for a nonlinear relationship between debt and long-run growth across countries, but no evidence for common debt thresholds within countries over time.
This paper argues that better governance practices can reduce the costs, risks and uncertainty of financial intermediation. Our sample covers high-, middle- and low-income countries before and after the global financial crisis (GFC). We find that net interest margins of banks are lower if various governance indicators are better. More cross-border lending also appears conducive to lower intermediation costs, while the level of capital market development is not significant. The GFC seems not to have had a strong impact except via credit risk. Finally, we estimate the size of potential gains from improved governance.
Can positive growth shocks from the faster-growing countries in Europe spill over to the slower growing countries, providing useful tailwinds to their recovery process? This study investigates the potential relevance of growth spillovers in the context of the crisis and the recovery process. Based on a VAR framework, our analysis suggests that the U.S. and Japan remain the key source of growth spillovers in this recovery, with France also playing an important role for the European crisis countries. Notwithstanding the current export-led cyclical upswing, Germany generates relatively small outward spillovers compared to other systemic countries, but likely plays a key role in transmitting and amplifying external growth shocks to the rest of Europe given its more direct exposure to foreign shocks compared to other European countries. Positive spillovers from Spain were important prior to the 2008 - 09 crisis, however Spain is generating negative spillovers in this recovery due to a depressed domestic demand. Negative spillovers from the European crisis countries appear limited, consistent with their modest size.
The December issue of the Research Bulletin looks at “Seven Questions about Climate Change” (Rabah Arezki and Akito Matsumoto). The Research Summaries review “Winning the Oil Lottery: The Impact of Natural Resource Extraction on Growth” (Tiago Cavalcanti, Daniel Da Mata, and Frederik Toscani) and “Malaysia: Achieving High-Income Status through Resilience and Inclusive Growth” (Alex Mourmouras and Naimh Sheridan). The issue also includes regular updates on new IMF Working Papers, Staff Discussion Notes, IMF books, and the IMF Economic Review.
Including contributions spanning a variety of theoretical and applied topics in econometrics, this volume of Advances in Econometrics is published in honour of Cheng Hsiao.
Germany has been a central player in discussions on the future architecture of Europe, and has been called on to play a larger role in supporting global and, especially, European recovery from the financial crisis that triggered the Great Recession. This book focuses on the possible economic role of Germany and shows that the quantitative effects of a German fiscal stimulus would be small on the heavily indebted euro area periphery countries that most need the boost. The book finds that Germany itself faces a growth challenge and that efforts to raise its own growth potential are important for Germany, and that more rapid growth of domestic demand will more powerfully stimulate European economic growth through its expanded demand for imports.
