Fiscal limits and sovereign default risk in Japan

It is widely known that Japan has the highest debt-to-GDP ratio among OECD countries. If Japan’s national debt continues to balloon, fiscal crisis may occur in the future. This paper develops a closed economy model with defaultable government debt and conducts a simulation to investigate future sovereign debt risk.First, we estimate the fiscal limit which is defined as the sum of the discounted maximum fiscal surplus in all future periods. It is assumed that a partial default occurs when the amount of government debt exceeds the fiscal limit. We calculate the revenue-maximizing tax rate at the peak of the Laffer curve to derive the fiscal limit. As a result, the estimated average fiscal limit in Japan is much higher than that in Greece. In the Japanese economy, households are more patient and desire greater savings from greater discount factor derived from a lower real interest rate. Household saving habits support government bonds. This is the main reason why the Japanese government could have had a massive debt in addition to some room to raise the tax rate. Second, we simulate the model, using the estimated fiscal limit and non-linear computational methods. If the government debt-to-GDP ratio continues to increase for the next 20 years, the default probability will be over 10% and the sovereign risk premium will be approximately 2%. Furthermore, the default probability will reach approximately 80% and the sovereign risk premium will be 10% 30 years later.     

Welfare Effects of Capital Taxation in a Small Open Economy

In a small open economy, the welfare effect of capital taxation depends on the allocation of the tax revenue as well as the tax system. If tax revenues are used to finance debt or government spending, an increase in either residential or territorial capital taxation will reduce the welfare of the representative individual. If tax revenues are transferred intergenerationally, an increase in the residential capital tax rate will increase the steady-state welfare when the after-tax interest rate is greater than the growth rate. If the revenue is rebated to the tax payer, an introduction of territorial capital taxation may increase welfare when the growth rate is relatively high. In the case where either the revenue from residential capital taxation is rebated to the tax payer or the revenue from territorial capital taxation is transferred intergenerationally, the welfare-maximizing tax rate appears to be zero.     

Is there any gain from social security privatization?

Increasing calls for a social security reform of switching from the pay-as-you-go (PAYG) system to a funded system has been seen in recent decades. This paper examines the effect of this reform on capital accumulation and the welfare of each generation. Three methods are used to finance the pension debt, government debt financing, tax financing, and government asset financing. With government debt or tax financing, the market equilibrium remains unchanged and all generations are as well off in the new system as in the PAYG system. Thus, switching from the PAYG system to a funded system is neutral. With government asset financing, the interest rate will decrease, private capital will increase, but the total output may either increase or decrease. The welfare effect is also ambiguous in general, depending on the rate of return of government assets. With plausible parameters, our simulation shows that the reform will lower the interest rate, increase private capital, and lower government capital in the short run, but raise government capital and increase output in the long run.     

BUDGETARY POLICIES, FOREIGN INDEBTEDNESS, THE STOCK MARKET, AND ECONOMIC GROWTH

This paper analyses a small open economy with overlapping generations,endogenous growth, and a risk premium on foreign debt. A balanced-budgetincrease in public consumption or a rise in government debtraises the ratio of foreign debt to domestic income and theinterest rate, but depresses economic growth. Supply-side policiesaimed at internalising production externalities boost foreignindebtedness, the interest rate, and economic growth. A higherglobal interest rate leads, if initial foreign indebtednessis not too large, to a lower foreign debt and, if a countryis dragged down by large levels of foreign debt, lower economicgrowth.     

Brazilian public sector disequilibrium

The Brazilian public sector disequilibrium, as measured by growth in the global net public sector debt to GDP ratio, is examined with and without the Plano Cruzado. Two models are used, one based upon a discrete time framework and the other upon a continuous time framework, to trace paths of the debt to GDP ratio for the rest of the decade concentrating on the 1985–1986 period. Two major conclusions are reached. The first, of a theoretical nature, is that discrete time models are inappropriate in an inflationary context as they severely underestimate the inflation tax. This is evidenced by the fact that without the Plano Cruzado and an assumed inflation rate of 350%, the debt to GDP ratio grows from 1985 to 1986 in the discrete time model while it declines for this period in the continuous time model. The second is that the Plano Cruzado may put strong pressure on government finances in the near future due to the drastic fall in the inflation tax. In this case, both models show an acceleration in the growth of the debt to GDP ratio, the more drastic results appearing in the continuous model. This conclusion seems to hold true even if one allows the government to trade debt for monetary base with the consequent increase in money demand due to lower inflation, to roll over its internal debt at a lower average interest rate, or to roll over its foreign debt outstanding at a lower average interest rate.     

Covid-19, Economic Growth and South African Fiscal Policy

Following years of fast-rising debt levels, we show that the Covid-19 crisis worsened an already deteriorating fiscal position in South Africa. To restore fiscal sustainability in the aftermath of the crisis some commentators argue that higher government expenditure will grow GDP sufficiently to stabilise the debt/GDP ratio. We reject this, showing that although a real increase in expenditure stimulates economic growth (a short-run, once-off effect), the public expenditure/GDP ratio exceeds the level at which an increase in the ratio positively impacts growth. We then explore the past efforts of government to maintain or restore fiscal sustainability by estimating a fiscal reaction function using a Markov-switching model. Following the impact of the Covid-19 crisis on the budget, we subsequently establish the deficit, expenditure and revenue adjustments that the government will have to make to restore fiscal sustainability. Finally, we consider the merits of introducing a debt ceiling.     

Impacts of household loan regulation on financial stability: evidence from Korea

The paper examines whether banking regulations and monetary policy contributed to controlling the fragility of household debt in Korea. The results show that housing loan regulations such as debt to income regulation contributed to a lower household debt delinquency ratio. Lowering the target interest rate provided additional stabilisation of the delinquency ratio. It is recommended that the government adopt an appropriate mix of regulation and monetary policy to control household financial fragility. The financial supervisory services need to be involved in managing debt to income regulation and minimising financial instability and financial market distortions. Further, the monetary authority has to adopt a more effective position in controlling the real lending interest rate and the delinquency ratio of household loans. Such a policy mix will improve effectiveness in controlling financial fragility, especially at a time of financial crisis.     

Endogenous Growth and External Balance in a Small Open Economy

This paper puts forward an intertemporal model of a small open economy which allows for the simultaneous analysis of the determination of endogenous growth and external balance. The model assumes infinitely lived, overlapping generations that maximize lifetime utility, and competitive firms that maximize their net present value in the presence of adjustment costs for investment. Domestic securities are assumed perfect substitutes for foreign securities and the economy is assumed small in the sense of being a price taker in international goods and assets markets. It is shown that the endogenous growth rate is determined solely as a function of the determinants of domestic investment, such as the world real interest rate, the technology of domestic production and adjustment costs for investment and is independent of the preferences of domestic households and budgetary policies. The preferences of consumers and budgetary policies determine the savings rate. The current account and external balance are functions of the difference between the savings and the investment rates. The world real interest rate affects growth negatively but has a positive impact on external balance. The productivity of domestic capital affects growth positively but causes a deterioration in external balance. Population growth, government consumption and government debt affect the current account and external balance negatively, but do not affect the endogenous growth rate.     

Fiscal sustainability in Japan

This paper investigates fiscal sustainability of Japan by providing a dynamic stochastic general equilibrium (DSGE) model that features the low interest rate of the government bond relative to the economic growth rate to mimic the actual data. We evaluate fiscal sustainability by investigating whether the expected path of the debt-to-GDP ratio stabilizes or increases without bound. The debt-to-GDP ratio depends crucially on the projected growth rate and the fiscal policy rule. If the government does not react to the current fiscal crisis, the debt-to-GDP ratio will increase without bound, and then the fiscal policy is not sustainable. If the fiscal rule uses Bohn’s (1998) idea that involves the response of the primary surplus to the debt, sustainability improves. This rule provides a useful and realistic reform plan in the short and long runs.     

Taxing Times in Indonesia: The Challenge of Restoring Competitiveness and the Search for Fiscal Space

Indonesia’s economic growth picked up slightly in mid-2016 but remains below the level demanded by government and popular aspirations. Despite a plethora of reforms intended to increase efficiency and productivity, some policies are perverse and longstanding problems of implementation remain. The share of manufacturing has declined, the real exchange rate has appreciated, exports have dwindled, and growth has been trending downwards. The banking sector is stable but inefficient, with wide net interest margins and numerous barriers to competition. Trade protection, particularly in basic food commodities, has created high costs that weigh particularly heavily on the poor. Declining government revenues have placed increasing pressure on the public budget, even as the current administration aims to increase spending on infrastructure and welfare and to enhance productivity. In an effort to increase revenues, the government has announced a tax amnesty program and other measures. In addition, Sri Mulyani Indrawati, the new finance minister, has taken steps to cut non-essential expenditure in order to secure high spending on infrastructure and at the same time keep within the 3% budget deficit limit stipulated by law. Although the overall debt situation is not yet alarming, declining revenues and budget cuts that do not fully reflect this decline are putting pressure on increasing debt levels. The government’s high-profile tax amnesty program was the major policy initiative implemented in the second half of 2016 that aimed to relieve this pressure. Despite widespread criticism of, and scepticism about, the tax amnesty (both within and outside Indonesia), its first phase had a much higher participation rate than most independent accounts expected. Revenues raised so far through the amnesty are less than 60% of the official target, but this is actually a strong result for the short term. The bigger question, however, is whether the amnesty is a key element of a more encompassing strategy to overhaul the system of taxation and tax administration.     

中国地方政府债务违约风险评估——基于债务可持续性分析框架

结合中国地方政府财政反应特征,文章在债务可持续性分析框架中,首次识别了基础盈余主动调整的有效性条件作为分析前提,进而完善了债务不可持续性的定义内涵和度量方法,最终建立了地方政府债务违约风险评估模型。凭借此模型,对中国地方政府债务违约风险进行了评估,主要结论如下：在经济增速不稳定背景下,施行顺周期财政政策的中国地方政府,容易落入基础盈余主动调整无效的境况,因而在对地方政府债务可持续性进行分析时,有必要考虑基础盈余主动调整的有效性;通过检验发现,新构造的债务不可持续概率和条件期望债务空间指标,均能较好反映地方政府债务违约风险,而单纯的债务率指标对地方政府债务违约风险无解释力;在2019年,天津、贵州和青海等地已处于财政疲劳引起的债务不可持续状态,内蒙古等六省的条件期望债务空间不足20%,其余省份的条件期望债务空间仍相对充裕;最后,通过考察债务可持续性的改善渠道又进一步发现,财政透明度的提高可有效降低地方政府债务违约风险。     

后危机时代美国财政可持续性研究

美国国债绝对额已跃居世界首位,美国财政可持续性受到世界各国的广泛关注。通过构建财政可持续性分析框架,结合经验数据实证分析,结果表明,尽管美国财政现阶段仍然处于可持续水平,但已经出现偏离稳态的迹象。进一步研究发现,未来美国债务货币化程度将不断加深,由此促使未来国债利率负担不断攀升,同时债务高位运行将导致经济增速回落,财政偏离可持续性水平的现象难以改变,如果美国没有调整财政政策,那么财政发生危机的概率极高。     

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.

地方政府债务对经济增长的影响——基于债务规模与债务结构的双重视角

在提出测算地方政府隐性债务新方法的基础上,基于所测算的数据,从债务规模和债务结构的双重视角,全面分析地方政府债务对经济增长的影响。结果表明:就债务规模而言,当地方政府债务率相对较低时,增加债务有助于促进经济增长,但是当地方政府债务率相对较高时,进一步增加债务对经济增长的推动作用将会减弱。就债务结构而言,当地方政府的隐性债务占比过高时,地方政府债务的扩张会对经济增长产生更为显著的负向影响,这主要是因为隐性债务对民间投资的挤出作用更强。因此,防范与化解地方政府债务风险,不应采取"一刀切"的策略,而应从债务规模和债务结构两个视角综合考量,为各地量身打造防范与化解债务风险的最优策略。     

A Note on Deficit,Implicit Debt,and Interest Rates

This short note revisits the long-standing issue of the relationship between government borrowings and interest rates using vector autoregression (VAR) models. In particular, we consider the dynamic impacts of both official deficit and implicit debt on the interest rates. Two measures of unfunded Social Security obligations (implicit debt) are examined. The recently developed generalized forecast error variance decompositions, which are invariant to the ordering of variables in VARs, are adopted. We find that temporary shocks to the official deficit do not cause real interest rate changes in the short term but do cause moderate changes in the long term. They have significant impact on nominal interest rates in both short and long horizons. The implicit debt also appears to have some moderate influence on real interest rates at long horizons.     

World public debt and real interest rates

Real interest rates appear to have risen in virtually all industrializedcountries in the 1980s and 1990s relative to levels that prevailedin earlier decades. There is concern that this may reflect higherpublic debt, which is crowding out private-sector activity.There has also been increasing international capital marketintegration, implying that interest rates in any country maybe sensitive to global fiscal developments. This paper estimatesthe effects of such fiscal developments on real interest ratesin nine industrial countries. The results imply that the increasein OECD-wide government debt since the late 1970s was a majorfactor in the rise in real interest rates.     

Absence of safe assets and fiscal crisis

This paper develops a fiscal crisis model that explains a mechanism under which low interest rates can coexist with Japan's large outstanding debt. The key idea is that when there is a strong home bias in the asset portfolio of domestic bondholders, these investors turn out to have no access to any assets that hedge fiscal risk. This explains why domestic investors do not request a risk premium on government bonds. In this environment, the interest rate and the default probability are low, and the government can sustain its large debt even under adverse fiscal conditions. As the interest rate does not rise fully to reflect the risk premium, the low interest rate is not always a signal of sound fiscal conditions. The welfare implications of financial market reform are mixed. This reform can improve welfare so long as the government can sustain the debt, but at the same time, it makes it difficult to sustain the debt because the interest rate rises. Quantitative easing is effective in lowering the risk premium.     

Fiscal and monetary policy in a monetary union: Credible inflation targets or monetized debt?

Fiscal and Monetary Policy in a Monetary Union: Credible Inflation Targets or Monetized Debt? —The paper examines the interrelationship between fiscal and monetary policy in a two-country monetary union. The worst scenario occurs when an independent central bank sets the nominal interest rate and responds to rising government debt/GDP ratios by monetization. The result is high inflation, high debt/GDP ratios and a large public sector. Government debt and inflation are contained if the governments bear sole responsibility for solvency, but the public sector remains excessively large. The best scenario occurs if the central bank removes the incentive for the governments to engineer surprise inflation by credible inflation targeting.     

Monetary Policy Impulses and Retail Interest Rate Pass‐Through in Asian Banking Markets

This paper considers the integration of financial markets and mutual influences of monetary policies in the USA and Asia based on monthly data from 1994 to 2007. We used panel‐type and time‐series and quantile panel‐type error correction models to test the influences of expected and unexpected monetary policy impulses on the interest rate pass‐through mechanism in the financial markets of 9 Asian countries and the USA. The empirics show that if interest rate integration exists in the financial markets, the following effects are observed: (i) positive impulses of unexpected monetary policy will lead to an increase in the long‐run multiplier of the retail interest rate; (ii) the adjustment of retail interest rates with short‐run disequilibrium will lead to an increase in the long‐run markup; and (iii) the empirical results of quantile regression prove that when the interest variation is greater than the 0.5th quantile and unexpected monetary policy impulses are greater than the expected monetary policy impulses, the short‐run interest rate pass‐through mechanism becomes more unstable.
