Changes In Public Debt Research Articles

A numerical analysis of Japan’s fiscal sustainability in a simple OLG model

We investigate the size of primary balance that can be sustained and the change in public debt and physical capital under transition dynamics in the Japanese economy. For our investigation, we construct a simple overlapping generations model. We find that a large primary surplus, 13.8–18.7% of GDP, is needed to prevent the public debt-to-GDP ratio from diverging infinitely. We also show that even if the large primary surplus can be maintained, the Japanese economy faces a sharp reduction in physical capital from 191 to 70.0% of GDP on the transition path.

Do the personal characteristics of finance ministers affect changes in public debt?

Using a unique dataset of the personal characteristics of national finance ministers in Western Europe (1980–2010), I show that a finance minister’s experience affects the national debt-to-GDP ratio. The increase in the debt-to-GDP ratio is smaller if the finance minister stays in office for an additional year. This result is robust to the inclusion of the personal characteristics of prime ministers and a measure of political stability. However, the magnitude of the effect is sensitive to how finance ministers are selected in the econometric model when more than one minister holds office during a particular year. The estimation of interaction terms further reveals that experience particularly matters in election years or in times of negative GDP growth because an experienced finance minister has the power to restrict the usual increase in the debt-to-GDP ratio. In contrast, a finance minister’s educational background and ideological leaning have no significant impact on the debt-to-GDP ratio.

Stock-Flow Adjustments and Fiscal Transparency: A Cross-Country Comparison

Over the past three decades, large and persistent discrepancies between the annual change in public debt and the budget deficit, so-called stock-flow adjustments, were a prominent feature of debt dynamics in many economies. The aim of this paper is to investigate the underlying determinants of such discrepancies and their relationship with fiscal transparency using data for 163 countries. Results show that such discrepancies can only be partly explained by balance sheet effects and the realization of contingent liabilities and that significant differences exist in average stock-flow adjustments across countries reflecting country-specific factors. The more fiscally transparent the country, the smaller these tend to be. The contribution of stock-flow adjustments to increases in debt is likewise smaller in countries with above average fiscal transparency. This may not be coincidental, as a lack of fiscal transparency may make it easier for governments to engage in deceptive fiscal stratagems.

International evidence on fiscal solvency: Is fiscal policy “responsible”?

We conduct a cross-country empirical analysis of fiscal solvency based on dynamic stochastic general equilibrium conditions. The results show evidence of fiscal solvency, in the form of a robust positive conditional response of the primary balance to changes in public debt, in panels for emerging and industrial economies and in a combined panel. Emerging economies show a stronger response and hence converge to lower mean debt–output ratios, as observed in the data. The results are weaker for countries with debt ratios exceeding panel means and medians. Hence, we can separate countries where fiscal solvency holds from those where it remains in doubt.

Human capital formation, public debt and economic growth

This paper presents an endogenous growth model with human capital, where human capital formation is the result of public education. The government finances expenditures in the schooling sector by the tax revenue and by public deficit. In addition, the government sets the primary surplus such that it is a positive linear function of public debt which guarantees that public debt is sustainable. The paper analyzes the structure of the growth model and derives implications of public debt. Further, a sensitivity analysis of the dynamics of the model is presented and it turns out that the parameter determining the reaction of the primary surplus to changes in public debt is decisive as concerns stability of the model.

Fiscal Rules for Debt Sustainability in Emerging Markets: The Impact of Volatility and Default Risk

The determinants of public debt dynamics - real interest rates, the real exchange rate, output growth and the primary fiscal balance - are typically more volatile in emerging market economies than in industrialised countries. Capital markets also typically demand higher interest rates from emerging markets when their debt dynamics deteriorate. This paper considers how these characteristics affect the choice of fiscal policy rules in emerging markets. We estimate an econometric model of the determinants of public debt dynamics on Brazilian data and use this model to simulate the effect of different fiscal policy rules for future paths of debt. We then derive the set of fiscal policy rules which stabilise public debt dynamics. We find that macroeconomic forecast uncertainty and feedback among the endogenous variables (principally from the debt-GDP ratio to interest rates) force the policy rule to be significantly more responsive to changes in public debt. Rules that would stabilise debt in a fully known world may not do so when the policymaker is faced with a realistic pattern of shocks. The method we employ may be a useful addition to the toolkit of domestic and international policymakers when assessing fiscal rules and debt sustainability.
