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.     

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.     

SHOULD SOUTH AFRICA HAVE A FISCAL RULE?

Over the past three decades many countries have struggled to find solutions to their persistent public sector deficits. For some the solution to this problem seemingly became the adoption of fiscal rules. This paper considers the applicability of one such rule, namely the output‐sensitive deficit rule of Taylor, and in particular its applicability to South Africa. The paper shows that its applicability in developing countries such as South Africa might be limited due to higher output volatility that may cause output‐sensitive deficit rules such as the Taylor rule to become more volatile. Such volatility in the deficit/GDP ratio may cause fears that government may not be able to maintain the stability of the debt/GDP ratio, thereby again introducing fiscal unsustainability. To address this problem the paper augments the Taylor rule to reduce the volatility in the public debt/GDP ratio and demonstrates how these rules would have performed in South Africa. It concludes that the augmented fiscal rule might contribute to both fiscal sustainability and economic stability in South Africa.     

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.     

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.     

FISCAL SUSTAINABILITY AND THE FISCAL REACTION FUNCTION FOR SOUTH AFRICA: ASSESSMENT OF THE PAST AND FUTURE POLICY APPLICATIONS

How does the South African government react to changes in its debt position? In investigating this question, this paper estimates fiscal reaction functions using various methods (ordinary least squares, threshold autoregressive, state‐space modelling and vector error‐correction model). This paper finds that since 1946, the South African government has run sustainable fiscal policy by reducing the primary deficit or increasing the surplus in response to rising debt. Looking ahead, this paper considers the use of fiscal reaction functions to forecast the debt/gross domestic product (GDP) ratio and gauging the likelihood of achieving policy goals with the aid of probabilistic simulations and fan charts.     

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.     

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.     

China's Nonfinancial Corporate Debt Dynamics

Since the global financial crisis broke out in 2008, China's nonfinancial corporate debt has been rising steadily and rapidly, posing serious threat to China's financial stability. China's rising corporate debt is mainly attributable to three factors: worsening capital efficiency, worsening corporate profitability and high funding costs. Based on a dynamic recursive model developed in the paper, we simulate the trajectories of China's corporate debt‐to‐GDP ratio, and find that if China fails to reverse the current trends in capital efficiency, corporate profitability and financing costs, China's nonfinancial corporate debt‐to‐GDP ratio will continue to rise without converging to a limit. Against most economists' intuition, given the current trends of changes in parameters, higher economic growth will not help China to escape the corporate debt trap. On the contrary, it will make China's corporate debt problem even worse. To avert a corporate debt crisis, China needs to speed up the structural reform and change the growth paradigm so as to enhance capital efficiency and firms' profitability, while reducing firms' financing costs.     

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.     

Public Debt and Economic Growth in Emerging Market Economies

This paper empirically studies the relationship between public debt and economic growth for selected emerging market economies by performing panel data estimations. The results reveal a statistically significant positive correlation between public debt and the subsequent growth rate of per capita gross domestic product (GDP). Population and investment are also positively correlated with per capita growth, whereas the initial level of real GDP per capita exerts a negative influence on growth, implying conditional convergence. Other variables such as the inflation rate, the trade balance or the exchange rate do not yield a statistically significant effect with respect to economic growth.     

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.

Bohn's Test of Fiscal Sustainability of the American State Governments

The dramatic fall in state revenues during the Great Recession and the resultant large budget deficits accentuated concerns about state fiscal sustainability. I employ a model‐based approach proposed by 1998 to test for sustainability. In this approach, a positive and significant reaction of the ratio of primary surplus ratio (s) to lagged debt constitutes a sufficient condition for sustainability. Based on a panel of 48 contiguous states (1961–2008) and several model specifications, I find robust evidence in favor of sustainability. Further analysis suggests that the adjustment of the components of s to debt is asymmetric with the revenue side bearing a heavier burden than the spending side. The response of s is also found to be asymmetric with respect to the level of debt. Finally, the magnitude of the response is larger in states with a higher degree of fiscal stringency in general and “own‐revenue” and “no‐deficit‐carryover” provisions in particular.     

International capital flows,debt overhang and volatility

This paper shows how international capital flows originate boom‐bust and sunspot episodes in a neoclassical growth model of a small, open economy. A limit is imposed on how much the economy can borrow from foreign creditors and it is made endogenous by assuming that the debt‐to‐GDP ratio is procyclical. The steady state is locally indeterminate when the credit multiplier is larger than some threshold level, whereas saddle‐point stability prevails when the credit multiplier is low enough. As a consequence, high levels of the credit multiplier lead to both booms followed by busts and sunspot‐driven volatility near the steady state, while, in contrast, low levels ensure monotonic convergence. Compared with saddle‐path equilibria, boom‐bust and sunspot equilibria are associated with both lower welfare and debt overhang, that is, a crowding‐out effect of credit: when the economy is highly leveraged, it uses savings to cut down foreign debt, at the expense of both human and physical investment. Numerical examples show that indeterminacy arises for debt‐to‐GDP ratios that fall within the range of available estimates. Finally, the effects of shocks to the world interest rate on output and consumption are amplified and persistent in the debt overhang regime.     

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.

FOREIGN DIRECT INVESTMENT IN ZIMBABWE: THE ROLE OF INSTITUTIONAL AND MACROECONOMIC FACTORS

The purpose of our research is to examine the impact of property rights on foreign direct investment (FDI) in Zimbabwe for the period 1964‐2005. While the macroeconomic determinants of FDI have been analysed to a considerable extent in past empirical work, the role of institutional factors such as the protection of property rights and the efficiency of the legal system has been underexplored. Using a multivariate cointegration framework, we use a newly constructed de jure property rights index for Zimbabwe to determine the impact of property rights on FDI. The empirical evidence shows that property rights are consistently an important explanatory variable of FDI in Zimbabwe, even after controlling for periods when there are no significant new foreign capital inflows. Other significant explanatory variables of FDI in Zimbabwe are the real gross domestic product (GDP), capital intensity, the external debt to GDP ratio, political instability as well as the educational levels.     

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.     

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.
