Public Revenue‐Expenditure Nexus in South Africa: Are there Asymmetries?

This paper re‐examines the government revenue and expenditure relationship in South Africa using Enders and Siklos' Threshold adjustment and Granger causality tests. The paper allows for structural breaks in the unit root and cointegration tests. The results indicate the absence of any asymmetries in both the threshold autoregression and momentum threshold autoregression specifications of adjustments in the South African's budgeting process. The estimated symmetric error‐correction models provide support for the fiscal synchronization hypothesis of government revenues and expenditures for long‐run and short‐run dynamic equilibrium. These findings indicate that the South African fiscal authorities should try to maintain or even improve the control of their fiscal policy instruments to sustain the prudent budgetary process.     

WAGNER'S LAW: AN ECONOMETRIC TEST FOR SOUTH AFRICA, 1960‐2006

The main objective for this paper is to test Wagner's law by analysing the causal relationships between real government expenditure and real income for South Africa for the period 1960‐2006. The paper tests the long‐run relationship between the two variables using the autoregressive distributive lag approach to cointegration suggested by Pesaran et al. We use the Granger non‐causality test procedure developed by Toda and Yamamoto, which uses a vector autoregression model to test for the causal link between the two. Evidence of cointegration is sufficient to establish a long‐run relationship between government expenditure and income. However, support for Wagner's law would require unidirectional causality from income to government expenditure. Therefore, cointegration should be seen as a necessary condition for Wagner's law, but not sufficient. This research does find a long‐run relationship between real per capita government expenditure and real per capita income. Results for the short‐run causality find bidirectional causality. On the basis of empirical results in this paper, one may tentatively conclude that Wagner's law finds no support in South Africa.     

FISCAL ILLUSION AT THE LOCAL SPHERE: AN EMPIRICAL TEST OF THE FLYPAPER EFFECT USING SOUTH AFRICAN MUNICIPAL DATA1

While South Africa operates a relatively decentralised governance and administrative structure, an important feature of the country's intergovernmental fiscal relations system is the gap that exists between the expenditure responsibilities of sub‐national authorities and their assigned revenue bases. The resulting vertical fiscal imbalance is mainly addressed via significant intergovernmental transfers to provinces and local governments. This factor presents strong a priori grounds for assuming that in the South African context, the heavy dependence of many local governments on intergovernmental transfers may generate fiscal illusion. Despite this, there have not been many empirical studies of fiscal illusion in South Africa's intergovernmental transfer system. This paper extends existing literature on fiscal illusion by using the fiscal year 2005/06 financial and expenditure data from 237 local government authorities in South Africa to evaluate the flypaper variant of the fiscal illusion hypothesis. Empirical results indicate that the marginal effects of municipal own‐source revenues on local expenditure exceed those of intergovernmental transfers. No statistical evidence in support of the flypaper hypothesis within the context of municipal expenditures in South Africa is found.     

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.     

The Revenue–Expenditure Nexus: The Experience of 13 African Countries

Abstract: The aim of this paper is to investigate the causal relationship between government revenue and government expenditure for 13 African countries within a multivariate framework using a modified version of the Granger causality test due to Toda and Yamamoto (1995) . The empirical evidence suggests that there was a bi‐directional causality running between expenditure and revenue for Mauritius, Swaziland and Zimbabwe; no causality in any direction for Botswana, Burundi and Rwanda; unidirectional causality running from revenue to expenditure for Ethiopia, Ghana, Kenya, Nigeria, Mali and Zambia; and a uni‐directional causality running from expenditure to revenue for Burkina Faso only.     

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.     

SOUTH AFRICA'S INTERGOVERNMENTAL FISCAL RELATIONS: AN EVOLVING SYSTEM

Across Africa, Latin America, Asia and the transition economies of Eastern Europe, the need to enhance the capability and capacity of sub‐national governments (SNGs) in providing public goods and services has become a main theme of development programmes. Central to this theme is the need to design an intergovernmental fiscal relations (IGFR) system that enhances the effectiveness of sub‐national governments in mobilizing revenues and implementing expenditure programmes. For South Africa, the post‐1994 dispensation has involved significant reforms to the structure and administrative capacity of the three spheres of government. Critical to these reforms is the need to formulate an IGFR framework that takes cognisance of South Africa's past, and serves as an effective policy tool in ensuring that public sector service delivery is well structured and managed. This paper provides an analysis of South Africa's evolving IGFR system. It outlines the historical evolution of the current IGFR system, identifies current challenges, and discusses implications that these challenges have for the functioning of the IGFR system. The general conclusion emerging from this study is that in the South African context, the key elements necessary for an effective IGFR system are in place. Ongoing reforms have improved the capacity of provincial and municipal authorities in carrying out their revenue and expenditure responsibilities. However, the evolving nature of South Africa's IGFR system requires that significant attention be devoted towards enhancing coordination between delivery departments and improving the capacity of many SNGs. These should not only aid the effective functioning of the IGFR system but also ensure that the gains of decentralisation are sustainable.     

ON THE CYCLICALITY OF SOUTH AFRICAN FISCAL POLICY

This paper examines the cyclicality of government revenue, spending and the key fiscal balances in South Africa during 1972‐2001. The results suggest that while government revenues were largely acyclical, government spending appears to have been predominantly counter‐cyclical, in line with the recommendations of neoclassical analysis. In addition, countercyclical government spending appears to have translated into a countercyclical policy stance overall. This finding contrasts markedly with the results from other empirical studies of South Africa and other emerging market and developing economies, which typically indicate procyclical fiscal policy.     

Fiscal Decentralization or Centralization: Diverging Paths of Chinese Cities

If fiscal decentralization promotes growth, why do some regions decentralize more than others? This article identifies the growing divergence of fiscal centralization among Chinese cities and explains it in a public finance framework. It argues that fiscal decentralization and its economy‐liberalizing effect entail significant short‐term fiscal risk. The more a locality relies on uncompetitive business ownership for fiscal revenue, the less likely fiscal decentralization is to occur. This article compiles a dataset of 20 provincial capitals between 1999 and 2016 to test for the connection between a city's tax base and its fiscal centralization level. It then pairs two “most similar” cities to trace how fiscal security concerns drove their fiscal and economic policies apart. This article adds a micro‐level perspective to the literature on fiscal federalism. By pointing out the fiscal constraints confronting local governments, it offers a new angle to understand the different growth paths of Chinese cities.     

SOUTH AFRICA'S TRANSITION TO A CONSOLIDATED BUDGET

The size of South Africa's fiscal stimuli, whether intended or not, has helped to avert negative consequences of the global financial downturn. With the economic cycle turning again, consolidation of deficits and a reduction of the level of debt are again the focus of policymakers. These outcomes are generally achieved by either increasing tax rates or cutting spending (discretionary fiscal policy), whereas an alternative option is to allow automatic stabilisers to consolidate budgets. This study attempts to answer whether cyclical factors or discretionary policy minimise output volatility and which one of the two presents a better policy option regarding uncertainty in real economic recovery. For this purpose, a small open‐economy gap model is built using South African data, where the budget deficit is endogenised by way of a fiscal policy “rule.” Sensitivity analyses and robustness checks are carried out using a structural vector autoregression. Given the estimates of both the automatic stabilisers as well as the components of discretionary fiscal policy, we are able to obtain impact multipliers on output and conduct scenario testing for optimal fiscal policy response towards fiscal consolidation as well as debt sustainability.     

Government revenue, expenditure, and national income: A granger causal analysis of the case of Taiwan

An understanding of the causalities among government receipts, outlays and national income in developing countries may shed some light on the type of government finance favorable to economic prosperity. However, there is no consensus in theories and empirical studies about the causal order among the three variables. This study evaluates their causal relationships in Taiwan within a framework of trivariate autoregression model. We find that there are feedbacks between GNP and government expenditure, on the one hand, and between government revenue and GNP, on the other hand. But there is only a one-way causality running from government revenue to government expenditure. The two bidirectional causalities seem to fit the expectation of fiscal activism. However, the causal flow from government revenue to expenditure indicates the constraint of the former on the latter. Therefore, we call this general causal pattern among the three variables in Taiwan as “constrained fiscal activism.”     

Stock price targeting and fiscal deficit in Japan: Why did the fiscal deficit increase during Japan’s lost decades?

The purpose of this paper is to explain why Japan’s fiscal deficit increased so dramatically in the 1990s and the 2000s. We focus on the role of “stock price targeting” to explain why the fiscal expenditure increased so much. After presenting a simple model to describe government behavior with an optimistic view about stock price and output growth, the paper tests whether the model can explain Japan’s fiscal expenditure. The empirical results, using biannual and high-frequency data of the 1990s and the 2000s, show that the stock price targeting can track Japan’s fiscal expenditure reasonably well, especially in the 1990s. They imply that without the stock price targeting, the total amount of biannual fiscal stimulus from 1992 to 2000 would have been lower by 2.5 trillion yen on average.     

THE CYCLICALITY OF MONETARY AND FISCAL POLICY IN SOUTH AFRICA SINCE 1994

This paper uses a structural vector‐autoregression approach to discuss the cyclicality of fiscal and monetary policy in South Africa since 1994. There is substantial South African literature on this topic, but much disagreement remains. Though not undisputed, there is growing consensus that monetary policy has contributed to the remarkable stabilisation of the South African economy over this period. The evaluation of the role of fiscal policy in stabilisation has been less favourable and there is little evidence that a countercyclical fiscal stance was a priority over this period. This paper considers these issues in an empirical framework that addresses some of the shortcomings in the literature. Specifically, it constructs a structural model in contrast with the reduced form models typically used in the South African literature, incorporates the dynamic interaction between monetary and fiscal shocks on the demand side and supply shocks on the other, and avoids controversy over “neutral” base years and the size of fiscal elasticities. The model confirms the consensus on monetary policy, finding it to have been largely countercyclical since 1994. On fiscal policy, this paper finds evidence of pro‐cyclicality, especially in the more recent period, though the policy simulations suggest that the pro‐cyclicality of fiscal policy has had little destabilising impact on real output.     

Public expenditure and revenue in China,1990-2009

This study examines the long-ran equilibrium relationship between government expenditure and government revenue in China from 1990 to2009, using co-integration techniques. Meanwhile, it examines the direction of causality relationship between the variables through Granger causalitytest. Empirical findings show that there is a long run equilibrium relationship between govenunent exponditure and revenue. Granger causality test indi-cate there is no hi-directional causal relationship between the two variables.     

Singapore's recurrent budget surplus: The role of conservative growth forecasts

Aided by strong economic growth the Singapore government has been able to keep both the tax rate and the government expenditure rate low and yet generate healthy budget surpluses year after year. Although the gap between the tax rate and the government expenditure rate is the obvious source of the surplus, this paper shows the presence of another subtle source, a surplus generated by conservative growth forecasts that lay the base for revenue projections. An omitted variable bias in a model based on the tax smoothing hypothesis led us to consider the role played by the growth forecast error in predicting the budget surplus. Our computations show that on average the under-prediction of the tax base (GDP) must have contributed about S$ 376 million (or about 13%) per year to the realized budget surplus over the period 1990–2005. This appears to be simply a by-product of the Government's philosophy of “fiscal prudence”.     

Has Fiscal Federalism Worked for Macroeconomic Purposes？ The Chinese Experience 1994-2003

China＇s central government undertook major tax regime reform in 1994 that was characterized by fiscal federalism. In hindsight, this reform might be viewed as being more emphatic towards the revenue side than the expenditure side. The reform has resulted in certain success both for revenue shifting and inflation fighting purposes. However, the reform and its subsequent follow-ups have not addressed some fundamental issues pertaining to China＇s government finance system, such as the overhauling of the function of government finance and redrawing lines between the central and regional governments with regard to their fiscal responsibilities and duties. Moreover, fiscal federalism might have actually increased fiscal burden on the economy, especially on domestic sectors of the economy. However, coupled with enhanced policy support for China＇ s external development, fiscal federalism might have helped to further accelerate resource shifts toward the external sector, thus resulting in an unprecedented rapid expansion in China＇ s exports since the mid1990s.     

Causal Relationship between Domestic Savings and Economic Growth: Evidence from Seven African Countries

This paper utilizes cointegration and the vector error‐correction model (VECM) to explore the causal relationship between economic growth and growth rate of domestic savings for Congo, Côte d’Ivoire, Ghana, Kenya, South Africa, and Zambia. Specifically, three analyses were undertaken. First, the time series properties of economic growth and domestic savings were ascertained with the help of the augmented Dickey–Fuller unit root procedure. Second, the long‐run relationship between economic growth and growth rate of domestic savings was examined in the context of the Johansen and Juselius (1990) framework. Finally, a Granger‐causality test was undertaken to determine the direction of causality between economic growth and growth rate of domestic savings. The results indicate one order of integration [I(1)] for each of the series. The results of the cointegration tests suggest that there is a long‐run relationship between economic growth and growth rate of savings. The results from the Granger‐causality tests indicate that contrary to the conventional wisdom, economic growth prima facie causes growth rate of domestic savings for most of the countries under consideration.

Fiscal decentralization and local expenditure policy in China

Since the tax-sharing reform in 1994, the Chinese fiscal system has exhibited a marked vertical fiscal imbalance—a mismatch between expenditure and revenue assignments—at the local levels, which may cause the common-pool problem in local governments' behavior. Using a large fiscal dataset at the county level from 1997 to 2006, this paper studies the effects of fiscal decentralization on local expenditure policy and analyzes how the vertical fiscal imbalance shapes these effects. The estimation results show that expenditure decentralization increases government spending and leads to a fund allocation with a larger weight on capital construction and smaller weights on education and administration. In contrast, revenue decentralization has little influence on local government expenditures. We show that the differences in the effects of expenditure and revenue decentralization can be attributed to the distortionary effects caused by the vertical fiscal imbalance and, thus, offer support to the importance of the common-pool problem at the county level of China's fiscal system.     

The government revenue and government expenditure nexus: empirical evidence from nine Asian countries

The nexus between government revenue and government expenditure has been an important topic in public economics. In this paper, we investigate evidence for cointegration and causality between government revenue and government expenditure for nine Asian countries. We use the recently developed bounds testing approach to cointegration and the conventional F-test to examine Granger causality. Our empirical results suggest that for three out of the nine countries government revenue and government expenditure are cointegrated. Our results on the direction of causation are mixed: (a) for Indonesia, Singapore, Sri Lanka in the short-run and for Nepal in both the short- and long-run we find support for the tax-and-spend hypothesis; (b) Indonesia and Sri Lanka are in conformity with the spend-and-tax hypothesis in the long-run; and (c) for other countries there is evidence of neutrality.
