The long-term consequences of external debt: Revisiting the evidence and inspecting the mechanism using panel VARs

We estimate a panel vector autoregression model to examine the relationship between external debt and economic growth. We use a large dataset based on 123 countries, classified according to income levels over the period 1990–2015. While total external debt appears to have a negative effect on growth rate overall, it is positively associated with income growth in the lower- and upper-middle income countries. Further disaggregating external debt into its components reveals that public external debt negatively affects economic growth across all income categories of countries, whereas the impact of private external debt is not statistically significant. We do not detect a common threshold level in the relationship between public debt and economic growth across countries. Savings and investment are the primary channels through which external debt impacts economic growth. These results are robust to various model specifications, additional controls, and identifying restrictions.     

Debt and Economic Growth in the European Union: A Panel Granger Causality Approach

This paper contributes to empirical investigation of the causality relationships between real gross domestic product (GDP) growth and the growth of three debt categories, namely public, foreign and private debt, in the universe of the 28 European Union (EU) countries during the past decade. Using panel Granger causality estimations, we find statistically relevant bidirectional causality relationships between public debt and economic growth for the periods both before and after the outbreak of the recent financial crisis. Moreover, there is clear evidence of economic growth’s contribution to decreasing public debt.     

ON THE IMPACT OF PUBLIC DEBT ON ECONOMIC GROWTH: DOES COUNTRY RISK MATTER?

This study examines the nonlinear impacts of four country risk indices on the debt‐growth nexus for 61 countries in a panel data framework. Our results show evidence of the different debt‐growth nexus under the different degrees of country risk. Under a high‐risk environment, a country's economic growth is harmed by raising its public debt. The negative effects public debt has on economic growth become weak under low political and financial‐risk environments, while an increase in public debt could help to stimulate economic growth under low composite and economic risk environments. In addition, the differences of countries' income and debt levels also lead country risks to have different effects on the debt‐growth nexus, suggesting that a country should borrow appropriately based on its current risk environments while improving economic performance.

Debt,seigniorage, and the Growth Laffer Curve in developing countries

The endogenous growth literature established the existence of an inverted-U curve between taxes and economic growth, namely a Growth Laffer Curve, but empirical evidence on this relationship in developing countries is rather limited. Given that seigniorage and public debt are also important means of financing public spending in these countries, we take into account in this paper their respective impacts on growth, as they might deform the existing relationship between taxes and growth. To this end, we develop a growth model with public investment as the engine of perpetual growth, and look for the effect of debt, tax and money financing on economic growth. We study in particular the way fiscal and monetary policies deform the Growth Laffer Curve in developing countries. An empirical section based on a panel of 100 developing countries over the period 1980–2010 provides both OLS-Fixed Effects and GMM-system estimations that support our theoretical conclusions, namely the existence of Growth Laffer Curves indexed by the levels of debt and of seigniorage.     

The Greek economy under the twin-deficit pressure: a demand orientated growth approach

This paper uses an alternative growth approach in line with Thirlwall’s model in order to predict economic growth in Greece taking into account internal and external imbalances caused by public deficit/debt and lack of trade competitiveness. It is shown that the simple Thirlwall’s Law (given by the product of the ratio of the income elasticities of demand for exports and imports, and the growth of foreign demand) over-predicts real growth in Greece while the more complete extended model, makes a closer prediction which is consistent with the high deficit/debt and current account deficit experienced in this country. The simulation approach shows that the most efficient policy to attain higher growth is to reduce external imbalances while policies to reduce internal imbalances are low growth enhancing.     

Reconsidering Wagner’s law: evidence from the functions of the government

We revisit Wagner’s law by function of government expenditure. Using data of 14 European countries between 1996 and 2013, we apply panel data and SUR methods to assess public expenditure–income elasticities. We find that some functions of government spending for a few countries (e.g. Austria, France, the Netherlands and Portugal) validate Wagner’s law. For the Netherlands, expenditures with environment protection increase more than proportionately to economic growth, and for France that is the case of spending in housing and community amenities. In addition, Greece is the only country where two public spending items react more than one to one to growth.     

Public Debt,Economic Growth and the Real Interest Rate: A Panel VAR Approach to EU and OECD Countries

ABSTRACT

We investigate the causal relationship between public debt ratios and economic growth rates for 31 EU and OECD countries. We estimate a panel VAR model that incorporates the long-term real interest rate on government bonds as a vehicle to transmit shocks in both the public debt to GDP ratio and the economic growth rate. We find no causal link from public debt to growth, irrespective of the levels of the public debt ratio. Rather, we find a causal relationship from growth to public debt. In high-debt countries, the direct negative impact of growth on public debt is enhanced by an increase in the long-term real interest rate, which in its turn decreases interest-sensitive demand and leads to a further increase in the public debt ratio.     

Reelection,growth and public debt

In this work we examine how economic growth affects public debt when interacted with reelection prospects. Reelection considerations shorten political time horizons and give rise to political myopia that exacerbates debt accumulation. That laxer institutional reelection restrictions (e.g., no term limits) mitigate this effect due to electoral accountability is well known. Incorporating growth, we find that this mitigation can be reversed because less myopic, and more accountable, incumbents put more emphasis on smoothing the effects of growth across generations. We test these predictions using an annual-based panel of U.S. states over the period 1963–2010. Our identification strategy rests on constitutionally-entrenched differences in gubernatorial term limits that provide plausibly exogenous variation in reelection prospects, and aggregate national TFP shocks that are exogenous to individual states. Our estimates indicate that when reelection is possible a one standard deviation positive income shock induces, within the same year, a relative increase of approximately $40 in real per capita public debt.     

External Debt and Growth in Emerging Economies

The paper studies the relationship between external debt and economic growth in a panel of emerging countries. A number of economists have proposed different methods of analysing the nexus between economic growth and public debt. The paper investigates the debt-growth nexus using a linear and non-linear specification, employing a panel ARDL model on 13 emerging countries during the period 1990–2016. The results show that there is no robust effect of debt on economic growth in the long run; however in the short run, external debt is negatively and significantly correlated to economic growth.     

Capital markets and capital allocation: Implications for economies in transition*

Recent work showing that a sounder financial system is associated with faster economic growth has important implications for transition economies. Stock prices in developed economies move in highly firm‐specific ways that convey information about changes in firms’ marginal value of investment. This information facilitates the rapid flow of capital to its highest value uses. In contrast, stock prices in low‐income countries tend to move up and down en masse, and thus are of scant use for microeconomic capital allocation. Some transition economy markets are coming to resemble those of developed economies, others those of low‐income countries. Stock return asynchronicity is highly correlated with the strength of private property rights in general and public shareholders’ rights in particular. Other recent work suggests that small entrenched elites in low‐income countries preserve their sweeping control over the corporate sectors of their economies by using political influence to undermine the financial system and deprive entrants of capital. The lack of cross‐sectional independence in some transition economies’ stock returns may be a warning of such economic entrenchment. Sound property rights, solid shareholder rights, stock market transparency, and capital account openness appear to check this, and thus contribute to efficient capital allocation and economic growth.     

Keynes,Employment Policy and the Question of Public Debt

This article provides a simple formalization of income–expenditure equilibrium in accordance with the Principle of Effective Demand, but augmented to explicitly incorporate public debt. This is utilized to explore the conditions required for simultaneous achievement of full-employment growth and a sustainable public debt trajectory—the latter understood as stabilization of the ratio of public debt to aggregate income, at some desired level. In the spirit of Keynes's economics, demand-led, full-employment growth, driven by government spending, is reconciled with public debt sustainability so understood. The policy implications, illustrative of Keynes's policy views, are then drawn out.     

Public debt dynamics with tax revenue constraints

We develop a dynamic model of public debt under the assumption that it is problematic for governments to implement fast increases of tax revenues, as new taxes require costly infrastructure and expertise that can be built only over time. In this environment, the standard condition requiring economic growth greater than interest costs is not sufficient to guarantee financial stability. Debt might become unstable if the gap between these two indicators falls below a given threshold. Our empirical analysis based on historical public finance data for the US provides strong support for the model. This study conveys a cautionary warning, because the debt of relatively safe borrowers may suddenly become unstable for instance because of a substantial deceleration in the growth of nominal income. These issues can be particularly relevant for those countries that do not have a modern and efficient tax collection system.     

How does public spending affect technical efficiency? Some evidence from 15 European countries

The relationship between government size and economic growth has been widely debated. Revisiting the subject from a distinct angle with respect to the mainstream approach, we provide an empirical analysis of the impact of government size on technical efficiency. The aim of this paper is to estimate the impact of public sector's size and of public expenditure components on 15 European countries’ technical efficiency from 1996 to 2014 by using a True Random Effect model. Using the total public expenditure as a proxy for the government size we estimate simultaneously national optimal production function and technical efficiency by controlling for income distribution and institutional quality. Our main findings show that the effect of public sector's size on efficiency is positive while the type of public expenditures may have both positive and negative impact. In more details, results suggest that education and health expenditures have a positive effect on technical efficiency, while others have a negative impact.     

Public capital in the 21st century: as productive as ever?

The global financial crisis and the euro area sovereign debt crisis that followed induced a rapid deterioration in the fiscal positions of countries across the globe. In the ensuing fiscal adjustment process, public investments were severely reduced in many countries. How harmful is this for growth perspectives? Our main objective is to find out whether the importance of public capital for long run output growth has changed in recent years. To this end, we expand time series on public capital stocks for 20 OECD countries and estimate country-specific recursive vector autoregressive (VAR) models. Results show that the effect of public capital shocks on economic growth has not increased in general, although results differ widely between countries. This suggests that the current level of public investments generally does not pose an immediate threat to potential output. Of course, this could change if low investment levels are sustained for a long time.     

The political economy of public debt

Public debt (as opposed to current taxation) alters the inter-temporal pattern of tax rates??it reduces current rates and increases future rates. Accordingly, whether the share of the cost of a given public expenditure is reduced or increased by debt for a given individual depends on the time profile of that individual??s income (tax base) vis-à-vis others?? incomes. Therefore, given the age-profile of income in virtually all Western countries, individuals will tend to be better off under current taxes the younger they are. If (as most standard models of political economy assume) individuals vote according to their economic interests, and if they are tolerably well-informed, then the pattern of support for public debt will track age. And increases in the median age of the population will lead to larger public debt. In other words, public debt policy collapses to a kind of demographic politics. This explanation may, however, be sensitive to assumptions about motives for bequest. Specifically, if bequestors seek to leave positive bequests and are motivated exclusively by the lifetime consumption of their heirs (as well as themselves) then the aged may, under plausible assumptions about the age of their heirs, prefer current taxes over debt.

On the time-varying nature of the debt-growth nexus: evidence from the euro area

This article uses the DCC-generalized autoregressive conditional heteroskedasticity model to investigate the existence of time-varying correlations between public debt and economic growth. To that end, we use annual data from both central and peripheral countries of the euro area for the period 1961–2015. The results suggest that the relationships between these variables are time-varying and that in some countries and for some periods, there is a positive association between them.     

Growth Effects of Fiscal Policy and Debt Sustainability in the EU

In this paper we study the relationship of fiscal policy and economicperformance of some core countries in the EU. Our aim is to find outwhether public deficit and public debt have consequences for real variables in the economies we consider. The background of our empirical study is a growth model that provides us with some predictions on the relationship between fiscal policy and economic growth. In a first step we then use Granger causality tests to analyze empirically whether some of the implications of our model arecompatible with the data. In a second step, we investigate whether the fiscalpolicies of the member states have been sustainable. Given this information,we then pursue the question of whether differences in the fiscal positions ofcountries have consequences as concerns the outcome of our empirical testsof step one. Finally, we study whether the impact of the public deficit ratiodepends on the magnitude of the debt ratio.     

Wagner’s law versus displacement effect

The public sector has grown dramatically over the past few centuries in many developed countries. In this article, we use wavelet methods to distinguish between two leading explanations for this growth – Wagner’s law and the displacement effect. In doing so, we use the long-term data of 10 OECD countries for a maximum time span of 1800–2009. We find that the validity of Wagner’s law is likely to vary strongly over time for each country. A roughly similar feature in most of the countries is that the law is less valid in the earliest stage of economic development as well as in the advanced stages, with the validity tending to follow an inverted U-shaped pattern with economic development. Further, our results indicate that the long-run growth of government size cannot be adequately explained by Wagner’s law. On the other hand, the displacement effect appears to account for the bulk of the growth in most of the countries.     

Cyclicality of taxes and external debt

In their work, Vegh and Vuletin have shown that statutory tax rates are acyclical in developed economies and procyclical in developing ones. This article extends their analysis by checking the interaction of statutory tax rates with countries’ external public debt. In general, we found that the value added tax rates are changed procyclically in both developed and developing countries (i.e. taxes are raised in bad times and reduced in good times). However, when the external debt is high, in the developing countries the procyclicality increases, while the opposite result holds for developed economies. This pattern occurs mainly in times of recession, when the need for loans is the highest. Although we found that there was a reduction in procyclicality after the 2000s, these findings pose a challenge to policy-makers, who should think of ways of dealing with lack of foreign funds in difficult times.
