The Impact of Longevity Improvements on U.S. Corporate Defined Benefit Pension Plans
Description: This paper provides the first empirical assessment of the impact of life expectancy assumptions on the liabilities of private U.S. defined benefit (DB) pension plans. Using detailed actuarial and financial information provided by the U.S. Department of Labor, we construct a longevity variable for each pension plan and then measure the impact of varying life expectancy assumptions across plans and over time on pension plan liabilities. The results indicate that each additional year of life expectancy increases pension liabilities by about 3 to 4 percent. This effect is not only statistically highly significant but also economically: each year of additional life expectancy would increase private U.S. DB pension plan liabilities by as much as $84 billion.

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.

Monitoring Systemic Risk Basedon Dynamic Thresholds
Description: Successful implementation of macroprudential policy is contingent on the ability to identify and estimate systemic risk in real time. In this paper, systemic risk is defined as the conditional probability of a systemic banking crisis and this conditional probability is modeled in a fixed effect binary response model framework. The model structure is dynamic and is designed for monitoring as the systemic risk forecasts only depend on data that are available in real time. Several risk factors are identified and it is hereby shown that the level of systemic risk contains a predictable component which varies through time. Furthermore, it is shown how the systemic risk forecasts map into crisis signals and how policy thresholds are derived in this framework. Finally, in an out-of-sample exercise, it is shown that the systemic risk estimates provided reliable early warning signals ahead of the recent financial crisis for several economies.

Fiscal Transparency, Fiscal Performance and Credit Ratings
Description: This paper investigates the effect of fiscal transparency on market assessments of sovereign risk, as measured by credit ratings. It measures this effect through a direct channel (uncertainty reduction) and an indirect channel (better fiscal policies and outcomes), and it differentiates between advanced and developing economies. Fiscal transparency is measured by an index based on the IMF’s Reports on the Observance of Standards and Codes (ROSCs). We find that fiscal transparency has a positive and significant effect on ratings, but it works through different channels in advanced and developing economies. In advanced economies the indirect effect of transparency through better fiscal outcomes is more significant whereas for developing economies the direct uncertainty-reducing effect is more relevant. Our results suggest that a one standard deviation improvement in fiscal transparency index is associated with a significant increase in credit ratings: by 0.7 and 1 notches in advanced and developing economies respectively.

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.

What Determines Government Spending Multipliers?
Description: This paper studies how the effects of government spending vary with the economic environment. Using a panel of OECD countries, we identify fiscal shocks as residuals from an estimated spending rule and trace their macroeconomic impact under different conditions regarding the exchange rate regime, public indebtedness, and health of the financial system. The unconditional responses to a positive spending shock broadly confirm earlier findings. However, conditional responses differ systematically across exchange rate regimes, as real appreciation and external deficits occur mainly under currency pegs. We also find output and consumption multipliers to be unusually high during times of financial crisis.

The Relationship Between the Foreign Exchange Regime and Macroeconomic Performance in Eastern Africa
Description: This study examines the relationship between the foreign exchange regime and macroeconomic performance in Eastern Africa. The study focuses on seven countries, five of which decisively liberalized their foreign exchange regimes. The study assesses the relationship between (i) growth and various determinants, including the exchange regime, the real exchange rate, and current account liberalization; and (ii) inflation and various determinants, including lagged inflation, the nominal exchange rate, the exchange regime, and liberalization. We find that in our sample, for the determinants of growth, investment and the real exchange rate are significant determinants but not the exchange regime or liberalization; and for inflation, the lagged inflation rate, nominal exchange rate, and the de facto regime are significant. Exchange rate pass-through is limited.

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.
