Government Expenditures and Revenues in Italy in a Long-run Perspective

The aim of this study is to investigate the sustainability of Italian public accounts using in a long-run perspective, using empirical tests on sustainability and solvency of the country’s fiscal policies. The results of unit root and stationarity tests show that government expenditures and revenues series are first-differences stationary. The empirical analysis considered both the entire period and two sub-periods (1862–1913, 1947–2013). Furthermore, we conduct tests on cointegration, which evidence that a clear long-run relationship between public expenditure and revenues emerges only for the years 1862–1913. In essence, the paper’s results reveal that Italy have sustainability problems in the republican age.

     

The Sustainability of Italian Public Debt and Deficit

In this paper, we analyse the sustainability of Italian public debt using a unique database, reconstructed by Forte (2011), which covers the years 1862–2013. The study focuses on empirical tests for the sustainability and solvency of Italian public finance. The results of unit root and stationarity tests show that public debt and deficit variables are non-stationary at levels, but stationary in first-differences form, or I(1). However, some breaks in the series emerge, given internal and external crises (wars, oil shocks, regime changes, institutional reforms). Therefore, the empirical analysis is conducted for the entire period, as well as two sub-periods (1862–1913 and 1947–2013). In essence, the paper’s results reveal that Italy has sustainability problems in the Republican age (1947-2013). Our Markov-switching dynamic regression model indicates the existence of two distinct states, both for public debt and deficit, with means and standard deviations rather different. Both states are extremely persistent.     

Twin Deficits in the European Countries

Public debt is a burden on future electors and taxpayers. In the absence of constitutional constraints, the incumbent government may show the cost of some public expenditures or tax reductions toward the future by financing them via new debt. However, according to the Ricardian theorem of public debt, the burden of debt is always anticipated via increased saving. If this theorem were true, a budget deficit would not affect the current account of the balance of payment. This paper analyzes the relationship between trade deficit and budget deficit. Using yearly data for the period between 1970 and 2010 in 33 European countries, we find evidence supporting the hypothesis that a chronic and robust budget deficit generates a trade deficit. The dynamic estimates show that a 1 % decrease in the government budget surplus/GDP ratio tends to deteriorate the current account/GDP ratio of 0.37 %, confirming previous studies with a different empirical basis. Dividing the sample period into two sub-periods (1970–1991 and 1992–2010), empirical findings show that current and past values of government budget influence trade balance in the first sub-period, whilst past values of government budget affect trade balance in the most recent years. Moreover, the estimated effect of government budget on current account balance is positive and equal to 0.48 and 0.30, respectively. For the high deficit countries, a long-run relationship between these variables has been found, showing that one percentage point increase in budget surplus/GDP ratio is associated with an improvement in the current account balance of roughly 0.15 percentage point. The estimated long-run government budget elasticity is negative and statistically significant, while the estimated speed of adjustment is equal to 0.33. Finally, Granger causality tests show mixed results.     

Public Expenditure and Revenue in Italy, 1862–1993

This study examines the long‐run equilibrium relationship between government expenditure and revenue in Italy from 1862 to 1993, using cointegration and causality techniques in the long as well as in the short‐run, through integrating the Error Correction Model (ECM) into the traditional Granger causality test. A Granger non‐causality test (due to Toda and Yamamoto) is also performed. Unit root tests have been applied in order to investigate the stationarity properties of the series. Moreover, three more homogeneous sub‐period (1862–1913; 1914–1946; 1947–1993) have been analysed. The nexus between public expenditure and revenue has been discussed also by Forecast Error Variance Decompositions (FEVDs). Empirical findings show that, for each sub‐period, the policy adopted reflects the prevailing paradigm of public finance. In fact, the ‘Tax‐and‐Spend' argument, received empirical support from the liberal period data. In contrast, the interwar years are in line with the ‘Spend‐and‐Tax' hypothesis. Finally, the “Fiscal Synchronization” hypothesis emerges in the republican ages.     

Sustainability and comovement of government debt in EMU Countries: A panel data analysis

We investigate the sustainability of fiscal policy in a set of 19 European Monetary Union (EMU) countries over the period 1970–2016. Panel unit root tests in the presence of cross-section dependence show that the government debt series is stationary, indicating that the solvency condition would be satisfied for these countries. This confirms the effectiveness of the austerity measures implemented by these member states. Moreover, an unobserved common factor drives the comovement of government debt in the Eurozone.
