Sub-Saharan Africa's rising public debt stock: Is there a cause for concern?

The study investigated public debt sustainability in sub-Saharan Africa (SSA) by testing the reaction of the primary balance to positive and negative shocks in public debts in a panel of 45 SSA countries. The study adopts the innovative nonlinear fiscal reaction function and the dynamic panel threshold model to account for the potential asymmetric phenomenon in the public debt series. In line with extant studies, the study found that public debts in SSA are weakly sustainable and there is a highly procyclical fiscal policy bias in SSA countries, particularly in resource-rich countries, indicating that governments' fiscal policy responses are expansionary during economic upturns and contractionary during recessions, which may aggravate recessions and worsen debt situations across SSA. For robustness, the study compares the results with emerging and developed economies. The results indicate that in advanced economies, public debt is sustainable and that fiscal policy response is countercyclical. The research and policy implications are discussed.     

Debt relief and fiscal sustainability

In this paper I analyze the relationship between fiscal policy,aggregate public sector debt sustainability, and debt relief. I develop a methodology to compute the fiscal policy path that is compatible with aggregate debt sustainability in the post-HIPC era. The model explicitly considers the role of domestic debt and quantifies the extent to which future debt sustainability depends on the availability of concessional loans at subsidized interest rates. The working of the model is illustrated for the case of Nicaragua, a country that in 2002 had one of the highest net present value of public external debt to GDP ratios. JEL no. F3, F34, F35.     

国债规模之我见

从1998年开始实施的以国债政策为主体的积极财政政策对我国经济发展功不可没。但是国债规模的日益扩大最终也可能产生其负面影响,因此对国债规模的研究日益受到我国经济学界和财政学界的广泛重视。同时,对国债规模的大小也是争论不休,存在的分歧较大。本文从对国债规模指标体     

Public debt and economic growth – economic systems matter

Most studies on the relationship between public debt and economic growth implicitly assume homogeneous debt effects across their samples. We –in accordance with recent literature– challenge this view and state that there likely is a great deal of cross-country heterogeneity in that relationship. However, other than scholars assuming that all countries are different, we expect that clusters of countries differ. We identify three country clusters with distinct economic systems: Liberal (Anglo Saxon), Continental (Core EU members) and Nordic (Scandinavian). We argue that different degrees of fiscal uncertainty at comparable levels of public debt between those economic systems constitute a major source of heterogeneity in the debt-growth relationship. Our empirical evidence supports this assumption. Continental countries face more growth reducing public debt effects than especially Liberal countries. There, public debt apparently exerts neutral or even positive growth effects, while for Nordic countries a non-linear relationship is discovered, with negative debt effects kicking in at public debt values of around 60% of GDP.     

Pollution in a globalized world: Are debt transfers among countries a solution?

We analyze the effects of a debt relief, that is, a decrease in public debt of a low-income country financed by a high-income country, on environmental quality. Under perfect mobility of assets, the debt relief increases the overall capital stock, and environmental quality when public abatements are sufficiently efficient. Welfare in both countries can also improve. Under a weak mobility of assets, capital does no more increase in the richest country, but environmental quality can improve. This comes from a crowding-out effect of debt in the high-income country, which does no more take place when the mobility of assets is significant.     

COMPARATIVE FISCAL RESPONSE EFFECTS OF DEBT RELIEF: AN APPLICATION TO AFRICAN HIPCS

As part of the efforts of the international donor community to scale up aid to Africa, substantial debt relief has been granted in recent years through the Heavily Indebted Poor Countries (HIPC) Initiative and its successor, the Multilateral Debt Relief Initiative. This paper tries to assess, for a sample of 24 African countries that have at least reached decision point status in the HIPC Initiative, to what extent this debt relief has created fiscal space in recipient country budgets, and what, on average, the actual fiscal response effects have been, relative to other types of aid. Inspired by the fiscal response literature, we model public finance behaviour as a system of structural equations and estimate the reduced form parameters in a Vector Autoregressive framework. In general, we are unable to find evidence that debt relief might provoke no or even perverse fiscal responses. On average, debt relief affects public finance behaviour in a desired way, with effects being most similar to those of its most direct substitute, programme grants.     

从债权国到债务国——美国国际债务模式转变的逻辑分析

国际债务危机最初都是起源于发展中国家,发展中国家是国际债务人。进入21世纪,国际债务模式呈现出新的变化,国际债务危机从"外围"向"中心"扩散;债务危机的形式由公司债务危机向主权债务危机转变,美国由原来世界最大债权国转变成为世界最大债务国,中国作为发展中国家已成为世界债权大国。美国国际债务模式转变的内在逻辑直接反映出发达国家利用债务对实施开放经济的发展中国家进行利益转移。中国作为债权国面临着诸多挑战,维护债权国利益是当务之急。     

Liquidity Risk and Banks' Asset Composition: Implications for Monetary Policy

Monetary growth models in which the government is a net debtor demonstrate that inflation adversely affects capital formation through the crowding out effect. Interestingly, the results are at odds with empirical evidence. In particular, recent studies point to an asymmetric relationship between inflation and the real economy across countries. Specifically, inflation and output are negatively correlated in poor countries. In contrast, inflation is associated with higher levels of economic activity in advanced economies. I present a monetary growth model with public debt, where the exposure to risk is inversely related to the level of income. In this setting, I demonstrate that the effects of monetary policy depend on the level of capital of the economy. In poor countries, banks' portfolios consist primarily of government liabilities. Therefore, a higher rate of money creation inhibits capital formation in these economies. In contrast, banks devote more resources toward productive uses in advanced countries. Consequently, monetary policy generates a Tobin effect.

Real time uncertainty in fiscal planning and debt accumulation in the euro area

Using real time data from the OECD this study explores euro area fiscal policies since the late 1990s. The results indicate that in the so-called periphery countries (Greece, Ireland, Italy, Portugal and Spain) ex ante fiscal plans have been more sensitive to economic cycles in the countercyclical direction than in the other euro area countries. Accumulated debt ratios in the periphery reflect high initial debt ratios, underlying deficit biases and cumulated errors in the data on macroeconomic imbalances. Overall, reliable statistics, balanced macroeconomic developments and longer-term policy orientation are crucial for sound and sustainable public finances.     

Unsustainable sovereign debt—is the Euro crisis only the tip of the iceberg?

As a direct effect of the financial crisis in 2008, public debt began to accumulate rapidly, eventually leading to the European sovereign debt crisis. However, the dramatic increase in government debt is not only happening in European countries. All major G7 countries are experiencing similar developments. What are the implications of this kind of massive deficit and debt policy for the long term stability of these economies? Are there limits in debt-ratios that qualitatively change policy options? While theory can easily illustrate these limits, where are these limits in real economies? This paper examines the relationship between sovereign debt dynamics and capital formation, and accounts for the effects of the 2008 financial crisis on debt sustainability for the four largest advanced economies. We contribute to the literature on fiscal sustainability by framing the problem in an OLG model with government debt, physical capital, endogenous interest rates, and exogenous growth. For the calibration exercise we extract data from the OECD for Germany as a stabilization anchor in Europe, the US, the UK, and Japan for almost two decades before the 2008 crisis. Except for intertemporal preferences, all parameters are drawn or directly derived from the OECD database, or endogenously determined within the model. The results of the calibration exercise are alarming for all four countries under consideration. We identify debt ceilings that indicate a sustainable and unsustainable regime. For 2011 all four economies are either close to, or have already passed the ceiling. The results call for a dramatic readjustment in budget policies for a consolidation period and long-term fiscal rules that make it possible to sustain sufficient capital intensity so that these economies can maintain their high income levels. Current conditions are already starting to restrict policy choices. However, the results also make it very clear that none of these economies would survive a second financial crisis such as the one in 2008.     

Monetary policy responses of Asian countries to spillovers from US monetary policy

Regional integration in Asia has been considerably enhanced over the past 20 years or so. Whether integration helps Asian countries reduce their vulnerability to external shocks or is a channel for spreading external shocks remains an open question. This paper assesses the spillovers from US monetary policy shocks to Asian countries while taking into account country‐specific characteristics in explaining differences in timing and magnitude of responses across Asian countries. The results indicate that policy interest rates in Asian countries generally respond to innovations in the Fed rate in the same direction, but typically with a lag of one quarter. However, the size of the responses varies across Asian countries with respect to country‐specific characteristics. These results suggest that an independent monetary policy may not be feasible for an Asian developing country that adopts a pegged rate regime while being extensively integrated into the world economy. However, the hypothesis of the impossible trinity may not be relevant in the case of China.     

Sustainability of public debt: evidence from Japan before the Second World War1

Japan defaulted on its public debt after the Second World War. This article addresses the question of how Japan lost its ability to sustain its public debt. We explore the sustainability of public debt in Japan before the War. We conduct statistical tests for the relationship between public debt and primary fiscal balance, and find that Japanese public debt was sustainable until 1931, and unsustainable in and after 1932. Narrative modes of analysis indicate that Japan lost its fiscal discipline because of the military's effective veto over budgetary processes and because of the absence of pressure for sound fiscal policy from international financial markets.     

地方公债制度的引入与风险防范

在我国经济发展放缓的背景下,中央提出实行积极的财政政策。引入地方公债制度是我国推行积极财政政策的一个可行选择,然而,它的引入会带来一些潜在的风险。因此,我国地方公债的制度安排必须以债务风险控制为核心,遵循行政监管与市场化发行相结合的原则,建立健全政府信息公开制度,完善政府投融资体制和投资决策责任制,这也是建立风险防范机制的主要内容。     

Government Debt Denomination Policies Before and After the EMU Advent

Through a cost-minimizing approach, this paper derives joint indicators to assess the efficiency of the mix of sovereign debt currencies between the countries belonging to the European Monetary Union (EMU). This theoretical insight enables us to explain why and how the introduction of the euro and the adoption of a common monetary policy may have led to significant changes in debt structure among EMU members, notably in favor of further euro-denominated debt. The interplay of intrinsic and strategic variables yields stylized facts that are consistent with country-specific empirical evidence. Following the sovereign debt crisis, we further emphasize the value-added of a coordinated debt issuance policy among EMU countries.     

Panama's exports and its sovereign debt

Conclusion Panama has a foreign debt that represents 81.2 percent of GNP. In absolute terms, this is not large by the standards established by countries such as Mexico. For countries like Panama, which are not in the severely indebted middle-income countries, there is a tendency to overlook them with debt assistance programs. In 1989, the Brady Initiative recognized the need to help SIMICs and the Paris Club also stepped in with rescheduling agreements primarily for SIMICs with high official debt. In the 1980s, Panama rescheduled $594 million in debt.That does not reduce the debt; rather, it gives the country more time to pay it off. Exports (or income) growth, if used exclusively to repay the debt, could accomplish that goal in 39 years. But the relationship between existing interest rates and export growth cannot be expected to endure for so long. In fact, it might be impossible for Panama to ever pay off its debt, particularly when its long-term and short-term sum exceed its GNP. If the ratio of debt-to-exports is indeed constant, then Panama will be able to outgrow the debt as long as export growth is greater than the cost of servicing the debt.     

The External Debt‐Servicing Constraint and Public‐Expenditure Composition in Sub‐Saharan Africa

Abstract: In the light of the current global financial and economic crises, how would governments in sub‐Saharan Africa (SSA) allocate their budgets across sectors in response to a binding debt‐servicing constraint? Within a framework of public‐expenditure choice, the present paper estimates constraint‐consistent debt‐service ratios and employs them in a Seemingly Unrelated Regression involving a five‐year panel for up to 35 African countries over 1975–94, a period preceding the Highly Indebted Poor Countries (HIPC) initiatives. While observed debt service is found to be a poor predictor of expenditure allocation, constraining debt servicing shifts spending away from the social sector, with similar impacts on education and health. The implied partial elasticity of the sector's expenditure share with respect to debt is estimated at 1.5, the highest responsiveness by far among all the explanatory variables considered, including external aid. Thus, if the social sector is to be protected, sufficient debt relief for SSA countries should be pursued.     

On budgetary policies, growth, and external deficits in an interdependent world

We investigate the effects of budgetary policies in a two-country model of overlapping generations and endogenous growth. In the presence of capital mobility, endogenous growth rates are equalized, but output levels do not converge. A worldwide rise in the public debt to GDP ratio or the share of government consumption reduces savings and growth. A relative rise in one country's debt to GDP ratio or its GDP share of government consumption results in a fall in external assets and its relative savings rate. In the short run, the fall in the savings rate is higher, and the country experiences higher current account deficits as a percentage of GDP.     

Debt policy under constraints: Philip II,the Cortes,and Genoese bankers

Under Philip II, Castile was the first country with a large nation‐wide domestic public debt. A new view of that fiscal system is presented that is potentially relevant for other fiscal systems in Europe before 1800. The credibility of the debt, mostly in perpetual redeemable annuities, was enhanced by decentralized funding through taxes administered by cities making up the Realm in the Cortes. The accumulation of short‐term debt depended on refinancing through long‐term debt. Financial crises in the short‐term debt occurred when the service of the long‐term debt reached the revenues of its servicing taxes. They were not caused by liquidity crises and were resolved after protracted negotiations in the Cortes by tax increases and interest rate reductions.
