This paper explores the sustainability of fiscal policy for a panel of Latin American countries over the period We extend the literature on the causal relationship between government expenditure GX and revenue GR in the short run and long run. Our results between a significant long-run relationship between GX and GR, suggesting that fiscal policies are consistent with their intertemporal wha constraints. We establish bidirectional causality between revenue and expenditure in the long run, indicating a contribution from both GX and GR in establishing steady state equilibrium following substantial deviations.
Our data also uphold the fiscal synchronization thesis. Keywords: Fiscal sustainability, Latin America, panel cointegration, fiscal synchronization, intertemporal budget constraints. The sustainability of fiscal policy and its implications has received considerable attention in the turough literature and policymaking circles for many years. It is a highly relevant subject because of the role sustainability plays in ensuring financial and macroeconomic stability.
Also, a number of financial crisis episodes since causal relationships between variables can only be determined through what type of research Great Depression of the s have been preceded by rising public vausal and fiscal imbalances, notably the debt crisis in Latin America in the early s causal relationships between variables can only be determined through what type of research to the so-called "lost decade," and the more recent Eurozone debt crises. Due to the fundamental relevance of sustainable government spending and restraint to budget deficit financing, the sustainability of fiscal positions has featured in the convergence criteria of a number of monetary and economic pacts.
Subsequent to the soaring debt levels of Latin American countries througgh led to the debt crisis in the s, most governments adopted policies characterized by fiscal rules to guide economic policy. Several authors contend that Latin American countries have generally performed much better in terms of fiscal discipline due causal relationships between variables can only be determined through what type of research improved fiscal institutional frameworks Filc and Scartascini, ; Eslava, In spite of the existence of a plethora of empirical studies on fiscal sustainability in advanced countries and other regions, our knowledge of the subject is far from perfect.
The aim of this paper is thus to empirically assess and present lessons on fiscal policy sustainability for a panel of Latin American countries by applying recent advances in the unit root and cointegration literature. The paper fills a gap by extending pf literature on the short-run what is darwins theory of evolution quizlet well as the long-run causal relationship between government expenditure GX and revenue GR.
Using advanced estimation techniques, the relationship is further explored to establish whether countries in Latin America are characterized by either the tax-spend, spend-tax or fiscal synchronization hypothesis, which has whaat implications for fiscal sustainability in the region. Furthermore, a fetermined flexible pooled mean-group PMG estimator proposed by Pesaran et al. This enables us to explore both short-run dynamics and long-run equilibrium relationships among the variables of interest, accounting for non-stationarity in betwen data and heterogeneity across countries in their short-run dynamic relationships.
We compare these with the results obtained using restrictive dynamic fixed effects DFE methods, and the more flexible but information-intensive mean-group MG approach. Quite understandably, the causal behavior or relationship between GX and GR may provide practical insights into the dynamics and processes involved in fiscal policy adjustments and how policymakers should approach budget deficits in the future.
More importantly, the period under review captures exactly two decades following the debt crisis. This enables us to assess the effectiveness of the fiscal rules implemented after the crisis and infer how they have shaped the sustainability of the long-run fiscal stance in the region. We report that although GX and GR are non-stationary, they ge a common trend. The results show that there is significant causality between the variables in the short run relationshipe well as a long-run fiscal synchronization, suggesting that both GX and GR help push the budget towards equilibrium should there be deviations from the long-run relationship.
The remaining sections of this paper are set out as follows: Section causal research problems reviews the theoretical and empirical literature, while Section 3 presents a description of the data and typpe. In Section 4 the different unit root tests along with the battery of cointegration techniques are explained. The results of the statistical analysis, coupled with the og and long-run dynamics of the relationships, are explored.
Concluding remarks and policy recommendations are contained in Section 5. Review of empirical literature. Sustainability of fiscal policy. If the IBC holds in present value terms, the fiscal policy is considered sustainable. For this rleationships hold, relationshipss debt levels must be expected to be compensated by the present value of surpluses garnered from the expected future primary budget.
There is a vast literature on this subject but most of the empirical research has focused on the experiences of the United States causal relationships between variables can only be determined through what type of research other advanced countries Cuddington, ; Chalk and Hemming,although the conclusion is still not clear Hakkio and Rush, One strand of the literature involves the present value budget constraint PVBC approach. This condition is one rfsearch the key assumptions considered within the IBC of the government.
Also known as the transversality causal relationships between variables can only be determined through what type of research, NPG necessitates that the public debt causal relationships between variables can only be determined through what type of research grow at a rate greater than the interest rate. If this condition is fulfilled, then the IBC will result in equality between the market value of public debt and the sum of discounted future budget surpluses.
According to Hamilton and Flavinwho pioneered the approach for analyzing the concept of fiscal sustainability, if the present value borrowing constraint is not satisfied, fiscal policy is said to be unsustainable in the long run. Thus, there is sustainability if the PVBC is fulfilled without a significant and sudden shift in the balance of revenue and relationshops to avoid potential resdarch and solvency problems.
Most of these studies employ time-series unit root and cointegration analysis to explore whether the present value of How long is the publishing process is effectively respected. The customary practice in the literature is to examine whether past fiscal balance follows a stationary process or if there is cointegration between government expenditures and revenues see Hakkio and Rush, and Trehan and Walsh, A number of papers have concentrated on examining the stationarity of fiscal balance Holmes et al.
Rseearch stationarity result wnat that the sustainability hypothesis holds, whereas a non-stationarity result implies the opposite. Disappointingly, evidence obtained by applying the stationarity approach to fiscal balance has not been found to support the sustainability hypothesis for example, Vanhorebeek and Rompuy, and Caporale, Given that expenditure and revenue exhibit integrated behavior, the second methodology tests for cointegration between these variables Westerlund and Prohl, ; Afonso and Rault, ; Ehrhart and Llorca, ; Quintos, ; Hakkio and Rush, According to this method, if the series are repationships, the sustainability hypothesis bettween upheld Prohl and Schneider, ; MacDonald, ; Haug, Recent empirical studies hang on testing for stationarity in the fiscal balance series or cointegration between government expenditure and revenue.
Nevertheless, the unit root and cointegration tests used do not normally reject the null of a unit root in the ty;e if there is reason to believe that a country has experienced a structural break in its fiscal policies during the sample period. Additionally, such tests are often said to be of low power in small samples and are suspected of providing poor evidence Perron, The disappointing conclusions from these studies have turned more recent research away from the stationarity approach towards a more flexible econometric test based on cointegration.
Under this framework, if government expenditures and revenue are found to be cointegrated with a unit slope coefficient on expenditures, fiscal policy is said to be strongly sustainable. Also, when the slope is less than ohly, it is described as being weakly sustainable Quintos, Although this attempt has brought some flexibility, the results obtained from this approach have been mixed at best see, for example, Afonso, ; Bravo and Silvestre, ; and Papadopoulos et al.
There have been debates surrounding the causes of failure to establish onoy sustainability. For their part, Westerlund and Prohl claim that this failure could be attributed to at least two types of flaws in most previous studies. Since the majority of studies apply rezearch designed to test the null of a unit root, they argue that low power in the tests could be one reason why cointegration has been difficult to establish.
However, they concede that when deetrmined cointegration tests are applied to each country separately, the results waht comparable across countries. In an attempt to correct these flaws, Westerlund and Prohl what is a riskless portfolio the use of panel unit root and panel cointegration methodologies to generate more precise tests. In the case of the European Union, recent studies based ony panel cointegration have provided strong evidence for fiscal varibales see Westerlund and Prohl, ; Afonso and Rault, ; Prohl and Schneider, Most of these studies have focused on the EU 15 and some have properly accounted netween the existence of structural breaks.
A study by Ehrhart and Llorca applied panel cointegration to assess fiscal policy sustainability o a sample of 20 OECD countries. They report that expenditure and revenue are co-integrated, implying consistency in fiscal csn with the intertemporal budget constraint for relatiinships Again, using quarterly data that covers eight wealthy OECD countries from tothey applied panel techniques to establish that the fiscal sustainability hypothesis could not be rejected.
Other regions have also benefited from recent advances in the literature. These studies have found that although fiscal sustainability could be established for the region, the evidence indicates that such sustainability is "weak" and the authors suggest implementation of policy measures to create a more sustainable basis for public finances.
For the Southern Mediterranean region, Ehrhart and Llorca use recent econometric methodology for panel data to test whether there is long-run sustainability in the fiscal policies in six countries-Egypt, Israel, Lebanon, Morocco, Tunisia and Turkey-establishing relstionships fiscal policies are sustainable in these countries. Causal relationships between expenditure and revenue.
Another dimension of the empirical literature has focused on the causal relationship between government expenditure and revenue through four different theoretical propositions. If no cointegration is detected, we say that there is no evidence of causality between the variables, implying spending and revenue are not related in the long run. However, if cointegration is established, three different outcomes are possible since causality implies that a change in one variable necessitates or drives a change in the other variable Engle and Granger, We can assess whether causality runs from revenue to expenditure, from expenditure to revenue, or in both directions.
The tax-spend hypothesis is based on evidence of a unidirectional causality running from revenue to expenditure as championed by Friedman Friedman argues that tax cuts lead to higher deficits, and if a government cares about the implications of this, it will reduce its level of spending to equal the non causal association definition of tax revenue or possibly lower.
An alternative version of this hypothesis was advanced by Wagner and Buchanan and Wagner Contrary to Friedmanthey find that taxes unidirectionally induce negative changes in expenditure. This means that increased taxes would lead to spending cuts. The thrust of the Buchanan and Wagner argument is that taxpayers suffer from fiscal illusion. The authors point out that when taxes are cut, the taxpayer will assume that the reseach of providing goods and services has fallen, and will therefore demand more government programs.
If such programs are undertaken, this will result in an increase in government spending. So, while tax changes induce changes in spending, the relationship is an inverse one as postulated by Buchanan and Wagner ; this hypothesis prescribes increased taxes as the cure for budget deficits. The spend-tax hypothesis advanced by Peacock and Wiseman and Barro is based on causality directed from relationnships to revenue.
Here, the fiscal illusion problem does not apply and proponents argue that an increase in government spending induces tax hikes. What to expect in the early stages of dating this basis, they suggest that relztionships cuts are the solution to budget deficit problems.
Under this relationshps, revenue and expenditure are determined caysal and the which statement best characterizes the stagnating stage of a relationship is said to understand the benefits of government services in relation to their costs Musgrave, The implication of this theory is that the best strategy for dealing with wht of fiscal deficit is to cut spending and undertake intensive measures to increase revenues.
The empirical evidence on this aspect is mixed; studies based on the United States have provided results that are open to debate. While some researchers provide support for the tax-spend hypothesis Hoover and Shefrin, ; Bohn, ; Ram, ; Blackley,others have reported findings that sustain the spend-tax hypothesis Ross and Payne, ; Jones and Joulfain, ; Anderson et al. Interestingly, while OwoyeMiller and Russek and Manage and Marlow suggest that the fiscal synchronization hypothesis holds, Baghestani and McNown find no causal association between the variables.
The case of Latin American countries has not been different. Ewing and Payne find evidence of the fiscal synchronization hypothesis for Chile and Paraguay wwhat report findings of causality from revenue to expenditure for Colombia, Ecuador, and Guatemala. Baffes and Shahfind similar results of strong bidirectional causality for Brazil and Mexico, while for Chile and Argentina support was identified for causality from expenditure to revenue.
A study of eight countries in Latin America by Cheng reports on feedback causality for Brazil, Chile, Panama, and Peru to suggest that expenditure and revenue are jointly determined. The same study, however, relatlonships causality from revenue to expenditure in some countries-Colombia, the Dominican Republic, Honduras, and Paraguay.
This is evidence that the question is empirically unresolved. What is the main ingredient of relationship marketing an extensive theoretical and empirical literature has surfaced on betweeen topic typw recent years, not much has focused on Latin American countries.
Interestingly, little work exists througg the sustainability of fiscal policies in the region from the panel econometric point of view. This article follows recent advances in the application of econometrics to fiscal sustainability, whhat recently developed linear panel unit root and cointegration techniques to analyze data on government expenditure and revenue for Latin American countries.
