Output gap estimates are subject to a wide range of uncertainty owing to data revisions and the difficulty in distinguishing between cycle and trend in real time. This is important given the central role in monetary policy of assessments of economic activity relative to capacity. We show that country desks tend to overestimate economic slack, especially during recessions, and that uncertainty in initial output gap estimates persists several years. Only a small share of output gap revisions is predictable ex ante based on characteristics like output dynamics, data quality, and policy frameworks. We also show that for a group of Latin American inflation targeters the prescriptions from typical monetary policy rules are subject to large changes due to output gap revisions. These revisions explain a sizable proportion of the deviation of inflation from target, suggesting this information is not accounted for in real-time policy decisions.
Estimates of the natural interest rate are often useful in the analysis of monetary and other macroeconomic policies. The topic gathered much attention following the great financial crisis and the Euro Area debt crisis due to the uncertainty regarding the timing of monetary policy normalization and the future path of interest rates. Using a sample of European countries (including several members of the Euro Area), this paper provides estimates of country-specific natural interest rates and some of their drivers between 2000 and 2019. In line with the literature, our findings suggest that natural interest rates declined during this period, and despite a rebound in the last few years of it, they have not recovered to their pre-crisis levels. The paper also discusses the implications of the decline in natural interest rates for monetary conditions and debt sustainability.
Economic theory offers several explanations as to why shifting expectations about future economic activity affect current demand. Abstracting from whether changes in expectations originate from swings in beliefs or fundamentals, we test empirically whether more optimistic or pessimistic potential output forecasts trigger short-term fluctuations in private consumption and investment. Relying on a dataset of actual data and forecasts for 89 countries over the 1990-2022 period, we find that private economic agents learn from different sources of in- formation about future potential output growth, and adjust their current demand accordingly over the two years following the shock in expectations. To provide a theoretical foundation to the empirical analysis, we also propose a simple Keynesian model that highlights the role of expectations about long-term output in determining short-term economic activity.
Fiscal rules can help to counteract the deficits and spending biases that too often originate in the political process. Rules that constrain spending--rather than the balance--allow fiscal policy to be countercyclical. Yet the design of effective spending rules is by no means straightforward. Should a rule be real or nominal? How comprehensive should the definition of spending be? What safeguards ensure the credibility of a rule? How do rules work in decentralized systems where regions and states are partially autonomous? France, Germany, Italy, and Spain--countries that could benefit from more emphasis on fiscal rules to constrain spending--are explored here as case studies.
Poor performance of the electricity sector remains a drag to economic efficiency and a bottleneck to economic activity in many low-income countries. This paper proposes a number of models that account for different equilibria (some better, some worse) of the electricity sector. They show how policy choices (affecting insolvency prospects or related to rules for electricity dispatching or tariff setting), stochastic generation costs, and initial conditions, affect investment in generation and electricity supply. They also show how credible (non-credible) promises of stronger enforcement to reduce theft result in larger (smaller) electricity supply, lower (higher) government subsidies, and lower (higher) tariffs and distribution losses, which in turn affect economic activity. To illustrate these findings, the paper reviews the experience of Haiti, a country stuck in a bad equilibrium of insufficient supply, high prices, and electricity theft; and that of Nicaragua, which is gradually transitioning to a better equilibrium of the electricity sector.
By the end of 2007, Chile's total factor productivity was lower than ten years earlier, a performance that contrasted sharply with the previous decade, when productivity grew by a cumulative 30 percent. This paper assesses productivity trends in Chile, by decomposing productivity into investment-specific technological change (associated with improvements in the quality of capital) and neutral technological change (related to the organization of productive activities). It concludes that investment-specific technological improvements have contributed significantly to long-term growth in Chile, in line with trends observed in other net commodity exporters, while neutral technological change has been slow.
The oil price decline creates an opportunity to dismantle energy subsidies, which escalated with high oil prices. This paper assesses energy subsidies in Latin America and the Caribbean—about 1.8 percent of GDP in 2011–13 (approximately evenly split between fuel and electricity), and about 3.8 percent of GDP including negative externalities. Countries with poorer institutions subsidize more. Energy-rich countries subsidize fuel more, but low-income countries are more likely to subsidize electricity, as are Central America and the Caribbean. Energy subsidies impose fiscal costs, hurting SOEs, competitiveness, and distribution. The paper overviews country experience with subsidy reform, drawing lessons.

The notable rebound of U.S. manufacturing activity following the Great Recession has raised the question of whether the sector might be experiencing a renaissance. Using panel regressions, we find that a depreciating real exchange rate, an increasing spread in natural gas prices between the United States and other G-7 countries, and in particular decreasing unit labor costs have had a positive impact on U.S. manufacturing production. While we find it unlikely for manufacturing to become a main engine of growth in the United States, we find that U.S. manufacturing exports could provide nonnegligible growth opportunities going forward.
Sound regional policies are essential for balanced and sustained economic growth. The interaction of federal and regional policies with cross-regional structural differences affect human and physical capital formation, the business climate, private investment, market depth, and competition. This paper summarizes the main elements of Russia's fiscal federalism, describes the channels through which it operates, and assesses the effectiveness of regional transfers in reducing regional disparities. The results suggest that federal transfers to regions contributed to reducing disparities arising from heterogeneous regional tax bases and fiscal revenues. This allowed regions with initially lower per capita income to increase human and physical capital at higher rates. There is little evidence for transfers contributing to increased cross-regional growth synchronization. The results also suggest that federal transfers did not significantly improve regional fiscal sustainability, a conclusion that is supported by the lack of convergence in per capita real income across Russian regions in the last 15 years.

The short answer: The size of the Russian State has not increased much in the last few years, but its economic footprint remains significant. Concretely, the state's size increased from about 32 percent of GDP in 2012 to 33 percent in 2016, not far from the EBRD's estimate of 35 percent for 2005-10. This is different from the mainstream narrative, which contends that the state's size doubled in the last decade. However, a deep state footprint is reflected in a relatively high state share in formal sector activity (close to 40 percent) and formal sector employment (about 50 percent). The deep footprint is also reflected in market competition and efficiency. Although sectors in which the state is present are more concentrated, concentration is large even in sectors where the state's share is low. This suggests the need to protect and promote competition, in particular in state procurement. Finally, state-owned enterprises' performance appears weaker than that of privately-owned firms, which may be subtracting from growth.
Despite conventional macroeconomic theory is based on the idea that demand shocks can only have temporary effects on unemployment, several European economies display highly persistent unemployment dynamics. The theory of hysteresis challenges this view and points out that, under certain conditions, demand disturbances can have permanent effects. In this paper, we find strong empirical evidence of unemployment hysteresis in advanced economies since the 1990s. Relying on an identification scheme instigated by an insider/outsider model, we study the effects of demand shocks allowing for cross-country heterogeneous dynamics, and exploit such heterogeneity to investigate what institutional settings have the potential to soften or amplify the effects of demand shocks. Our results indicate that strengthening labor market institutions that promote a faster adjustment of real wages, removing disincentives for firms to hire and for workers to be employed, and improving the matching between labor supply and labor demand can lessen the effects of adverse demand shocks and lead to a faster reversion of unemployment rates to pre-shock levels.
The combination of stagnant growth and high levels of income inequality renewed the debate about whether a more even distribution of income can spur economic activity. This paper tests for cross-country convergence in income inequality and estimates its impact on economic growth with a heterogeneous panel structural vector autoregression model, which addresses some empirical challenges plaguing the literature. We find that income inequality is converging across countries, and that its impact on economic growth is heterogeneous. In particular, while the median response of real per capita GDP growth to shocks in income inequality is negative and significant, the dispersion around the estimates is large, with at least one fourth of the countries in the sample presenting a positive effect. The results suggest that the negative effect is mainly driven by the Middle East and Central Asia and the Western Hemisphere across regions, and emerging markets across income levels. Finally, we find evidence that improved institutional frameworks can reduce the negative effect of income inequality on growth.
