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.     

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.     

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.     

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 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.     

Market reforms and consumption puzzles in China

China exhibits above average savings and below average consumption as shares of total economic activity when compared with other countries. At the same time, to create more balanced growth at home and rebalance key bilateral trade and capital flow relationships, China's leadership is trying to increase domestic demand. To complement studies that investigate the high rate of savings in China, this study focuses on the variation in consumption as a share of GDP across provinces between 1979 and 2004. Drawing on well-established consumption theories and work done on savings behavior in China, this paper develops an empirical investigation of the variables hypothesized to influence the pattern of consumption across regions.We find that the normal, economic variables have a small explanatory power if significant at all, while the key variables influencing the macro consumption share are structural, and mostly related to government behavior. For example, local government expenditure on health and education is significant and has a relatively large effect on consumption. Consistent with this we also find a positive relationship between consumption shares and the size of the state sector and the share of tax revenue in GDP. We also find some evidence that financial development has a positive effect on consumption shares. Our results suggest that in order for domestic consumption to be increased in the future, new public and private options to replace the declining security and responsibility of the prior state-dominated system will be needed.     

Capital Markets and Capital Formation in Australia, 1945–1990

This survey article continues the author's examination of the interaction between domestic capital markets and capital formation by studying the 45 years after the end of World War II. (Part 1 appeared in AEHR 37 (3) 1997.) The significant rise and the sustained increase in the ratio of gross domestic capital formation to gross domestic product (GDP) posed challenges to local deposit taking institutions and capital markets to mobilize savings. The changing balance between public and private investment, and between investment by businesses and households, was reflected in the relative importance of government and private debt, and equity. The capital markets and financial institutions proved themselves to be adaptable enough to finance more than 90 per cent of postwar capital formation. However, the increasing inward and outward flows of foreign direct investment have weakened the nexus between the supply of domestic savings and capital formation.     

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.     

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.     

Structural change in the Chinese economy and changing trade relations with the world

This paper examines the impact of structural change in China, in particular a reduction in the savings rate, an increase in the share of skilled workers, and an increase in productivity in technologically advanced manufacturing sectors targeted by Made in China 2025. Baseline projections until 2040 are generated with the WTO Global Trade Model, a dynamic computable general equilibrium model. With the modelled structural changes, the Chinese economy is projected to reorient its focus increasingly onto the domestic economy, raising the share of private household and government consumption in GDP, turning China's trade surplus into a trade deficit, reducing China's share in global exports, raising the share of services in both production and exports, shifting the destination markets of Chinese exports from developed to developing countries, and changing its pattern of comparative advantage away from sectors like light and heavy manufacturing to electronic and machinery equipment. The large bilateral trade surplus vis-a-vis the United States is projected to fall to almost zero.     

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.     

固定汇率制度下的财政政策:开放经济宏观经济学的拓展

本文主要建立在新开放主义宏观经济学理论上,进一步拓展和分析不同财政政策在固定汇率制度下对国民经济的影响,如消费、产出与汇率等。通过引入迭代模型的基本框架从而打破传统的李嘉图等价假设,我们发现因为有限生命代理人把所购买的国债看作是一种净财富,所以通过发行债券融资而导致的政府支出暂时的增加毫无疑问地将会增加本国居民相对于国外居民的消费水平。而另一方面,由于汇率水平固定不变和短期的价格粘性,政府支出增加的部分将平均分配给本国和外国商品。因此,政府支出暂时的增加将会减少本国的净国外资产头寸。而对于货币政策来说,本国居民相对消费水平的增加将导致本国货币升值压力,本国中央银行为了维系固定汇率水平不得不被动地增加货币供给。     

Export Dependence and Sustainability of Growth in China

This paper examines the contribution of exports to growth in China since the early years of the decade. It is estimated that, despite a high import content ranging between 40 and 50 percent, approximately one‐third of Chinese growth before the global crisis was a result of exports, due to their phenomenal growth of some 25 percent per annum. This figure increases to 50 percent if spillovers to consumption and investment are allowed for. The main reason for excessive dependence on foreign markets is underconsumption. This is due not so much to a high share of household savings in GDP as to a low share of household income and a high share of profits. It is argued that China can no longer maintain such high growth rates for its exports, and, therefore, needs to turn to consumption‐led growth by expanding the share of wages and household income in GDP and accelerating public spending in social infrastructure.     

Sovereign credit spreads and the composition of the government budget

This paper investigates the relationship between sovereign credit spreads and the composition of the government budget. The key result of this paper is that governments that invest more and spend less on consumption have significantly lower sovereign credit spreads. This finding is in accordance with the endogenous growth theory, which predicts a positive impact of government investment and a negative impact of government consumption on the long-term growth rate. Finally, a broader tax base significantly reduces sovereign credit spreads. A possible explanation may be that governments with more tax receipts are less likely to have liquidity problems to finance their debt charges.

How China Could Contribute to a Benign Global Rebalancing？

Our study shows that China could contribute to an orderly global rebalancing using a package of policies to stimulate its domestic consumption. These policies include a progressive appreciation of the RMB, fiscal stimulation by increasing expenditure on education, health care, social safety nets and poverty reduction, income policies to reduce inequality and to strengthen wage income, and reforms of the financial system to improve financial efficiency and to mitigate financial constraints. By implementing such policies, China＇ s external surplus could be narrowed and its domestic imbalances improved. The excessively high savings rate could be lowered and the share of household consumption increased, even though GDP growth would moderate slightly.     

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.     

Government Bias in Education,Schooling Attainment,and Long‐Run Growth

A surprising cross‐country stylized fact is that higher public spending on education tends to lower the long‐run growth rate of per capita GDP and the returns to schooling. This is contrary to the conventional wisdom that education is a major driver of growth. In this article, we revisit this issue and try to understand these puzzling facts in terms of an endogenous growth model. Our cross‐country calibration of the growth model predicts that countries with a greater government involvement in education experience lower schooling efforts and lower growth.
