Output Gap Uncertainty and Real-Time Monetary Policy

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.

The Macroeconomic Relevance of Credit Flows: An Exploration of U.S. Data

This paper exploits the Financial Accounts of the United States to derive long time series of bank and nonbank credit to different sectors, and to examine the cyclical behavior of these series in relation to (i) the long-term business cycle, (ii) recessions and recoveries, and (iii) systemic financial crises. We find that bank and nonbank credit exhibit different dynamics throughout the business cycle. This diverging cyclical behavior of output and bank and nonbank credit argues for placing greater emphasis on sector-specific macroprudential measures to contain risks to the financial system, rather than using interest rates to address any vulnerabilities. Finally, we examine the role of bank and nonbank credit in the creation of financial interconnections and illustrate a method to conduct macro-financial stability assessments.

Financial Deepening in Mexico

International comparisons reveal that—even controlling for a host of explanatory factors—credit depth is exceptionally low in Mexico. Using panel data methods linking credit growth and fundamentals, this paper estimates a long-term gap between actual and expected credit of about 40 percent of GDP. Possible explanations include the history of banking crises, the large informal sector and an inefficient legal system. Using a disequilibrium regression approach, this paper also finds that supply factors are particularly important as determinants of credit in Mexico. Recent financial reforms address many of the supply constraints, but their success will depend on implementation. The main challenge going forward will be to support financial deepening, while limiting risks to financial stability.

Saving in Latin America and the Caribbean: Performance and Policies

This paper analyzes saving patterns and determinants in Latin America and the Caribbean (LAC), including key policy variables and regimes. The review of previous empirical studies on LAC saving reveals contradictions and omissions. This paper presents empirical results of an extensive search of determinants of private and public saving rates, adding previously neglected variables (including different measures of key external prices and macroeconomic policy regimes), in linear form and in interactions with other saving determinants. It analyzes statistical differences in saving determinants between LAC and the rest of the world in a nested econometric framework, and discusses differences across three country subgroups within LAC. The results highlight commonalities and differences in saving behavior between LAC and other world regions, as well as within LAC, identifying the role of key policy variables and regimes.

Central Bank Financial Strength in Central America and the Dominican Republic

This paper examines the financial strength of central banks in Central America and the Dominican Republic (CADR). Some central banks are working off the effects of intervention in distressed financial institutions during the 1990’s and early 2000’s. Their net income has improved since then owing to lower interest rates, a reduction in interest bearing debt, and recapitalization transfers. Claims on the government have fallen, but remain high and are typically reimbursed at below-market rates, and capital is negative when adjusting for this. Capital is sufficient to back a low inflation target given that the income position is supported by unremunerated reserve requirements. Capital is likely to increase over time, but only gradually, leaving countries vulnerable to macroeconomic risks. The capacity of CADR central banks to engage in macroeconomic stabilization would benefit from increased emphasis on low inflation as the primary objective of monetary policy and a stronger commitment by governments to recapitalization.

A Crude Shock; Explaining the Impact of the 2014-16 Oil Price Decline Across Exporters

The decline in oil prices in 2014-16 was one of the sharpest in history, and put to test the resilience of oil exporters. We examine the degree to which economic fundamentals entering the oil price decline explain the impact on economic growth across oil exporting economies, and derive policy implications as to what factors help to mitigate the negative effects. We fi nd that pre-existing fundamentals account for about half of the cross-country variation in the impact of the shock. Oil exporters that weathered the shock better tended to have a stronger fi scal position, higher foreign currency liquidity buffers, a more diversifi ed export base, a history of price stability, and a more flexible exchange rate regime. Within this group of countries, the impact of the shock is not found to be related to the size of oil exports, or the share of oil in fi scal revenue or economic activity.
