Japanese government debt and sustainability of fiscal policy

We construct quarterly series of the revenues, expenditures, and debt outstanding for Japan from 1980 to 2010, and analyze the sustainability of the fiscal policy. We pursue three approaches to examine the sustainability. First, we calculate the minimum tax rate that stabilizes the debt to GDP ratio given the future government expenditures. Using 2010 as the base year, we find that the government revenue to GDP ratio must rise permanently to 40–47% (from the current 33%) to stabilize the debt to GDP ratio. Second, we estimate the response of the primary surplus when the debt to GDP ratio increases. We allow the relationship to fluctuate between two “regimes” using a Markov switching model. In both regimes, the primary surplus to GDP ratio fails to respond positively to debt, which suggests the process is explosive. Finally, we estimate a fiscal policy function and a monetary policy function with Markov switching. We find that the fiscal policy is “active” (the tax revenues do not rise when the debt increases) and the monetary policy is “passive” (the interest rate does not react to the inflation rate sufficiently) in both regimes. These results suggest that the current fiscal situation for the Japanese government is not sustainable.     

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.     

An endeavor to estimate seigniorage before the end of and immediately after the Pacific War

This is the first research paper to analyze seigniorage in Japan before, during, and after the Pacific War. As a result of logically categorizing various definitions of seigniorage (opportunity cost approach, monetary approach, and inflation tax), we conclude that these differences pivot on the issue of whether to confine the scope of debts, which is reduced by unexpected inflation, to the usual general government debt or to expand it to the integrated government debt including the monetary base of the Bank of Japan. We also point out the possibility that, in light of the degree of reduction in government debt as a percentage of GDP during and after the Pacific War, the monetary approach or inflation tax (the cases of confining the taxation base to the usual general government debt) are appropriate means to estimate seigniorage obtained by the general government.     

Public Debt,Economic Growth and Inflation in African Economies

We analyse the relationship between public debt, economic growth and inflation in a group of 52 African economies between 1950 and 2012. The results indicate that the limits of public debt are negatively related to economic growth and exhibit, from a given level of debt, an inverted U behaviour regarding the relationship between economic growth and public debt. Briefly, the high levels of public debt are coincident with reduced rates of economic growth and rising levels of inflation. Our results for three specific geographical areas resemble those of the overall analysis, despite some differences. In North African countries, the growth rates of the gross domestic product (GDP) and inflation also show an inverted U behaviour as the ratio of public debt/GDP increases. The highest rate of economic growth is recorded when the ratio of public debt/GDP is below 30% of GDP and corresponds to an average inflation rate of 5.33%. An identical behaviour of the GDP growth rates and inflation also appears in Sub‐Saharan countries until the third interval (60–90%). However, the highest growth rate of the GDP and GDP per capita is registered when the public debt/GDP ratio is in the second interval (30–60%). For the countries of the Southern Africa Development Community, the highest average rate of economic growth (6.8%) is similar to North African countries, when the ratio public debt/GDP is below 30% of GDP, with an average inflation rate of 11%. A number of robustness analyses were performed and the great majority of them confirm the general analysis.     

Factors affecting the external debt-servicing capacity of African nations: An empirical investigation

While there have been a vast number of studies and international discussions on developing nations’ debt servicing capacity, not much attention has been focused on the African dimension. This article examines the determinants of debt reschedulings for forty-five African nations over the twelve-year period 1976 to 1987. A logit model of the macroeconomic variables affecting the probability of rescheduling is developed. The findings indicate that debt-service ratio, reserves to imports ratio, debt-service payments to capital inflow ratio, GDP growth rate, rate of domestic inflation, and net government deficit to GDP ratio are important indicators of debt servicing capacity. The overall results, while providing strong support for some of the often-mentioned causes of the African debt crisis, are seen to hold useful possibilities for both the debtor countries and international creditors.     

Impacts of macroeconomic policies on the Mexican output

This paper examines the potential effects of macroeconomic policies, stock market performance, exchange rate fluctuations, and other related variables on real GDP in Mexico. Extending the works by Arango and Nadiri (1981) and Bahmani‐Oskooee and Ng (2002), and applying comparative‐static analysis, possible effects of a change in the exchange rate or government debt on the equilibrium output are examined. All the variables have unit roots and are stationary in first difference. There is a long‐run stable relationship between real GDP and the right‐hand‐side variables. The GARCH(p,q) (Engle 2001) model is applied to estimate regression parameters. Real GDP is positively associated with real M2, government deficit spending, stock prices, U.S. output, and world oil prices, and negatively affected by the government debt ratio, peso depreciation, and the expected inflation rate. Therefore, fiscal policy to incur more debt needs to be pursued with caution, and both net exports and money demand need to be considered in studying the impact of exchange rate fluctuations on output.     

Capital flows and exchange rates: recent Korean and Taiwanese experience and challenges

We first study the characteristics of the financial crisis and its impacts on Taiwanese and Korean economies. We have examined 22 macroeconomic fundamentals, such as GDP, inflation rates, government budget, trade balance, external debt, money supply, and ratios of average monthly imports and cumulative inward portfolio investment to international reserves, and compared with an extensive data set of the two countries. The comparisons point out that the macrofundamentals of both countries are basically the same, except the international finance sector. After defining currency crisis and banking crisis, the causes of crises are identified as the nominal exchange rates and the short-term external debt-to-international reserves ratios. In view of this, we use cointegration and causality tests to examine the relationship between these two time series. We have found a unidirectional causality from the short-term debt ratio to the exchange rate for Korea, but no causality between the two for Taiwan. The paper ends with some discussions on the lessons and challenges from the experience of the two countries.     

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.     

The Swedish banking crisis: roots and consequences

The article analyses the Swedish banking crisis in the early1990s. Newly deregulated credit markets after 1985 stimulateda competitive process between financial institutions where expansionwas given priority. Combined with an expansive macro policy,this contributed to an asset price boom. The subsequent crisisresulted from a highly leveraged private sector being simultaneouslyhit by three major exogenous events: a shift in monetary policywith an increase in pre-tax interest rates, a tax reform thatincreased after tax interest rates, and the ERM crisis. Combinedwith some overinvestment in commercial property, high real interestrates contributed to breaking the boom in real estate pricesand triggering a downward price spiral resulting in bankruptciesand massive credit losses. The government rescued the bankingsystem by issuing a general guarantee of bank obligations. Thetotal direct cost to the taxpayer of the salvage has been estimatedat around 2 per cent of GDP.     

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.     

Why not chock-full employment?

Needlessly high levels of unemployment are a contributing factor to a wide range of social ills, which would be substantially alleviated by driving unemployment to a low level of about 1.5 percent. This will require substantial increases in government deficits and debt. Recent trends in the ratio of private profit-seeking invested capital to GDP have been steady or slightly downward, while the ratio to GDP of desired private asset holdings has been growing, leaving a gap that must be filled by a growing government debt if GDP is to grow rapidly to a full employment level. The corresponding deficits are the means whereby the flow of income payments is enhanced, market demand increased, full employment is achieved and a corresponding expansion of private investment induced, leaving future generations to enjoy an enhanced heritage of capital in place and a more experienced work force. Meeting debt service payments from a prosperous economy will be less onerous than meeting current debt service requirements from an economy in the doldrums. If inflation becomes a problem, it must be taken care of by methods that do not involve unemployment, such as the use of marketable gross markup warrants.

Fiscal Consolidation and the Public Sector Balance Sheet in South Africa

Between 1994 and 2008 the South African government reduced its debt/GDP ratio from almost 50% to 27%. Unfortunately this reduction was accompanied by a significant decrease in government's fixed capital/GDP ratio from 90% to 55% – fiscal sustainability might have been restored, but government's balance sheet did not improve. A similar story can be told for State Owned Enterprises. Since the Great Recession the fiscal situation worsened markedly – the public debt ratio again approaches 50%. To restore fiscal sustainability this article suggests that the government faces two options: (1) to create room for future countercyclical policy, the government must cut current expenditure and reduce the public debt/GDP ratio to its pre‐crisis level, or (2) substitute much‐needed infrastructure capital expenditure for current expenditure while stabilising the debt/GDP ratio at its post‐crisis level. Given that the much lower fixed capital/GDP ratio inhibits economic growth, the latter option might be more sensible.     

China's sovereign debt: A balance-sheet perspective

We analyze China's sovereign debt by constructing balance sheets for China's government and public sector. We find that China's government debt-to-GDP ratio is lower than that of most large developed economies. We also find the debt-to-asset ratio of China's government and public sector significantly lower than its own historical height (1998–2002). Local government debt is mainly to finance infrastructure investments. Local government debt risk is amplified by two mismatches. The first is the income-expenditure mismatch between central and local governments. The second is the maturity mismatch of short-term debt and long-term infrastructure investments. The maturity mismatch may cause short-term repayment difficulties.     

The Policy Challenge with Floating Exchange Rates: Turkey’s Recent Experience

This paper evaluates the developments in the Turkish economy in light of the Central Bank of Turkey’s (CBT) policies during a recent period of floating exchange rate system (March 2001–July 2003). It is found that the CBT was effective in containing volatility and reducing the average inflation rate while there was a strong recovery of output. However, there are accumulated risks in the economy. Particularly, the extreme appreciation of the Turkish lira during this period and the record level of real interest rates give the impression that the current state of the economy is fragile. Unless the government accelerates the structural reform process and pursues sound fiscal policies to reduce the public sector borrowing requirement and the debt ratio, an adverse shock to the system may trigger a reversal of fortune.     

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.     

Towards an analysis of tax effects on labour market and allocation: A micro/macro approach

Summary Tax effects on labour market and allocation are analysed with a sectoral model which is based on the microeconomic theory of the behaviour of economic agents. The model contains a highly disaggregated household sector, an enterprise sector, equilibrium unemployment on the labour market and a detailed modelling of institutional aspects of the tax and social security system. The model is calibrated for 1985. Simulation results show that temporary increases of world trade and higher value-added tax rates do not affect the equilibrium unemployment rate in the long run. A higher replacement rate of unemployment benefits increases unemployment and a tax reform containing lower marginal and average tax rates reduces unemployment.The authors thank F.J.H. Don, C.J.J.

The External Debt Situation in Indonesia: Performance and Prospects

In interviews with bankers, government economists and academic observers, most of them attributed the absence of an Indonesian debt crisis during 1982–84 to the fact that a significant portion of external public debt, an average of 37 percent, was long-term concessionary loans from foreign governments and international agencies. Our analysis challenges this conventional explanation. We show that if Indonesia (1) had paid the same effective interest rate as Mexico, (2) had the same maturity structure as Mexican debt, and (3) had the same export-GNP ratio as Mexico, then its average 1980–82 total debt service-export ratio would have been 84.4% instead of the actual 30.1%. Our decomposition shows that concessional interest rates account for 5.8 percentage points of the gap, maturity structure for 17.7 percentage points and export orientation for 30.8 percentage points.
We have concluded that the major cause for the favorable 1982–84 outcome is competent management of the exchange rate. The absence of protracted exchange rate overvaluation from 1979 onward was fundamental in maintaining a strong nonoil tradeable sector. The nonoil tradeable sector was able to earn enough foreign exchange to service Indonesian debts when the external shock of high interest rates increased debt service payments and the recession in industrialized countries lowered the price of oil. The absence of extended exchange rate overvaluation also kept the external debt down and the maturity structure on the long side by not encouraging capital flight. We ascribe this use of the exchange rate to protect the tradeable sector as much to the existence of an influential political constituency consisting of neoclassical economists, Javanese peasants and Outer Island residents as to balance-of-payments considerations.
We recommend an aggressive exchange rate policy and two sets of supplementary measures to reduce the probability of a debt crisis in the medium 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.     

Optimal government investment and public debt in an economic growth model

This paper establishes a nonlinear theoretical model and uses panel smoothing transitional regression to study the optimal levels of government investment and public debt in a growth model using a panel dataset of 65 developed and developing economies over the period 1991–2014. The empirical results show that the effect of government investment on economic growth is decreasing as the level of expenditure rises. When the government investment/GDP ratio reaches a certain point (threshold), the effect of government investment could change from positive to negative. The effect of public debt on economic growth demonstrates a similar pattern. Our results suggest that there must exist an optimal level of government investment or public debt as far as economic growth is concerned, although the optimal level may vary in different economies. The government investment/GDP and public debt/GDP ratios of China were respectively 15.66% and 41.14% in 2014. These levels did not reach their respective thresholds and hence their effects on economic growth were still in the positive territory. Despite the expansion of government investment and public debt in China after the world financial crisis, their scales had not affected the country's economic growth during the data period.     

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.
