On the Extrapolation with the Denton Proportional Benchmarking Method
Description: Statistical offices have often recourse to benchmarking methods for compiling quarterly national accounts (QNA). Benchmarking methods employ quarterly indicator series (i) to distribute annual, more reliable series of national accounts and (ii) to extrapolate the most recent quarters not yet covered by annual benchmarks. The Proportional First Differences (PFD) benchmarking method proposed by Denton (1971) is a widely used solution for distribution, but in extrapolation it may suffer when the movements in the indicator series do not match consistently the movements in the target annual benchmarks. For this reason, an enhanced formula for extrapolation was recommended by the IMF’s Quarterly National Accounts Manual: Concepts, Data Sources, and Compilation (2001). We discuss the rationale behind this technique, and propose a matrix formulation of it. In addition, we present applications of the enhanced formula to artificial and real-life benchmarking examples showing how the extrapolations for the most recent quarters can be improved.

Evolution of Debt Sustainability Analysis in Low-Income Countries: Some Aggregate Evidence
Description: The Debt Sustainability Analysis (DSA) for low-income countries (LICs) is a standardized analytical tool to monitor debt sustainability. This paper uses DSAs from three periods around the time of the global economic crisis to analyze the projected trajectories of debt ratios for a sample of LICs. The aggregate data suggest that LIC vulnerabilities improved on the whole during the period prior to the crisis, and that the crisis had a strong short-run impact on key ratios of debt (debt-to-GDP, -exports, and -fiscal revenues) and debt service (debt service-to-exports, and -revenues). Although projected debt burdens increased following the crisis, debt indicators tend to return to their pre-crisis levels over the projection horizon. This may reflect a strong and durable policy response by LICs towards the crisis, or also reflect specific assumptions on the long-run growth dividends of public external debt.

Quantifying Impact of Aging Population on Fiscal Space
Description: This paper quantitatively investigates how population aging trend affects fiscal space measured as unused revenue generating capacity by utilizing a standard neoclassical growth model. A calibration exercise for G-7 countries shows that France, Germany and Italy suffer greater revenue impact from a given reduction in hours worked due to their larger government expenditure. Corrective measures such as pension reform and flexible expenditure policy would be required in order to mitigate the impact of aging on fiscal space.

Monetization in Low- and Middle-Income Countries
Description: The degree of an economy’s monetization, which has an important implication on economic growth, can be affected by the conduct of monetary policy, financial sector reform, and episodes of financial crises. The paper finds that monetization--measured by the ratio of broad money to nominal GDP-- in low- to middle-income countries is significantly correlated with per-capita GDP, real interest rates, and financial sector reform. It suggests that maintaining an upward momentum in monetization can be an important policy objective, particularly for low-income countries, and that monetary and financial sector policies need to be conducive to enhancing monetization.

Global and Regional Spillovers to Pacific Island Countries
Description: Regional integration of Pacific Island countries (PICs) with Australia, New Zealand, and emerging Asia has increased over the last two decades. PICs have become more exposed to the region’s business cycles, and spillovers from regional economies are more important for PICs than from advanced economies outside the region. While strong linkages with Asia would help in the event of a global downturn, PICs remain particularly vulnerable to global commodity price shocks. In this paper, we use a Vector Error Correction Model (VECM) for each PIC to gauge the impact of global and regional growth spillovers. The analysis reveals that the impact on PICs’ growth from an adverse oil shock would be substantial, and in some cases even larger than from a negative global demand shock. We also assess the spillovers to the financial sector from the deterioration of the global outlook. PICs should continue to rebuild policy buffers and implement growth-oriented structural reforms to ensure sustained and inclusive growth.

Fiscal Foresight and Information Flows
Description: News - or foresight - about future economic fundamentals can create rational expectations equilibria with non-fundamental representations that pose substantial challenges to econometric efforts to recover the structural shocks to which economic agents react. Using tax policies as a leading example of foresight, simple theory makes transparent the economic behavior and information structures that generate non-fundamental equilibria. Econometric analyses that fail to model foresight will obtain biased estimates of output multipliers for taxes; biases are quantitatively important when two canonical theoretical models are taken as data generating processes. Both the nature of equilibria and the inferences about the effects of anticipated tax changes hinge critically on hypothesized information flows. Different methods for extracting or hypothesizing the information flows are discussed and shown to be alternative techniques for resolving a non-uniqueness problem endemic to moving average representations.

Policy Analysis and Forecasting in the World Economy: A Panel Unobserved Components Approach
Description: This paper develops a structural macroeconometric model of the world economy, disaggregated into thirty five national economies. This panel unobserved components model features a monetary transmission mechanism, a fiscal transmission mechanism, and extensive macrofinancial linkages, both within and across economies. A variety of monetary policy analysis, fiscal policy analysis, spillover analysis, and forecasting applications of the estimated model are demonstrated, based on a Bayesian framework for conditioning on judgment.

Local Governments’ Fiscal Balance, Privatization, and Banking Sector Reform in Transition Countries
Description: Several transition economies have undertaken fiscal decentralization reforms over the past two decades along with liberalization, privatization, and stabilization reforms. Theory predicts that decentralization may aggravate fiscal imbalances, unless the right incentives are in place to promote fiscal discipline. This paper uses a panel of 20 transition countries over 19 years to address a central question of fact: Did privatization help to promote local governments’ fiscal discipline? The answer is clearly ‘no’ for privatization considered in isolation. However, privatization and subnational fiscal autonomy along with reforms to the banking system - restraining access to soft financing - may prove effective at improving fiscal balances among local governments.

Intra-Regional Spillovers in South America: Is Brazil Systemic After All?
Description: Shocks stemming from Brazil - the large neighbor in South America - have historically been a source of concern for policy-makers in other countries of the region. This paper studies the importance of Brazil’s influence on its neighboring economies, documenting trade linkages over the last two decades and quantifying spillover effects in a Vector Auto Regression setting. While trade linkages with Brazil are significant for the Southern Cone countries (Argentina, Bolivia, Chile, Paraguay, and Uruguay), they are very weak for others. Consistent with this evidence, econometric results show that, while the Southern Cone economies (especially Mercosur’s members) are vulnerable to output shocks from Brazil, the rest of South America is not. Spillovers can take two different forms: the transmission of Brazil-specific shocks and the amplification of global shocks—through their impact on Brazil’s output. Finally, we also find suggestive evidence that depreciations of Brazil’s currency may not have significant impact on output of its key trading partners.

Exchange Rate Pass-Through in Sub-Saharan African Economies and its Determinants
Description: This paper analyzes the exchange rate pass-through to domestic prices and its determinants in sub-Saharan African countries. It finds that the pass-through is incomplete. The pass-through is larger following a depreciation than after an appreciation of the local currency. The average elasticity is estimated at about 0.4. It is lower in countries with more flexible exchange rate regimes and in countries with a higher income. A low inflation environment, a prudent monetary policy, and a sustainable fiscal policy are associated with a lower pass-through. The degree of pass-through has declined in the SSA region since the mid-1990s following marked improvements in macroeconomic and political environments.
