Public debt is one of the important economic variables that quantitatively describes a nation's economy. Because bankruptcy is a risk faced even by institutions as large as governments (e.g. Iceland), national debt should be strictly controlled with respect to national wealth. Also, the problem of eliminating extreme poverty in the world is closely connected to the study of extremely poor debtor nations. We analyze the time evolution of national public debt and find "convergence": initially… 
Bankruptcy risk model and empirical tests
It is found that the Zipf exponent increases during market crashes, implying that firms go bankrupt with larger values of R, and proposes a coupled Simon model that simultaneously evolves both assets and debt with the possibility of bankruptcy.
Zipf rank approach and cross-country convergence of incomes
We employ a concept popular in physics —the Zipf rank approach— in order to estimate the number of years that EU members would need in order to achieve convergence of their per capita incomes.
Fat tails, long-range correlations and multifractality as emergent properties in nonstationary time series
This work investigates the behavior of an agent-based model consisting of N agents which interact with each other via fixed rules and shows that fat-tailed distributions, long-range correlations, heteroscedasticity and multifractality arise as N becomes large.


When is External Debt Sustainable?
The article empirically examines the determinants of debt distress, defined as periods in which countries resort to any of three forms of exceptional finance: significant arrears on external debt,
Debt, Deficits, and Finite Horizons
Many issues in macroeconomics, such as the level of the steady state interest rate, or the dynamic effects of government deficit finance, depend crucially on the horizon of economic agents. This
A Sensitivity Analysis of Cross-Country Growth Regressions
A vast amount of literature uses cross-country regressions to find empirical links between policy indicators and long-run average growth rates. The authors study whether the conclusions from existing
The Level and Composition of Public Sector Debt in Emerging Market Crises
The paper examines the evolution of public sector debt levels and structures in 12 emerging market countries around the time of financial crises. In particular, it focuses on whether the debt
Determinants of Economic Growth: A Cross-Country Empirical Study
Research on economic growth has exploded in the past decade. Hundreds of empirical studies on economic growth across countries have highlighted the correlation between growth and a variety of
Convergence across States and Regions
A key economic issue is whether poor countries or regions tend to grow faster than rich ones: are there automatic forces that lead to convergence over time in the levels of per capita income and
The Debt Burden and Debt Maturity
At low and moderate levels of government debt, there appears to be little relation between the level of debt and its maturity. But at high levels of debt, a strong inverse relation emerges. We start
Influence of corruption on economic growth rate and foreign investment
We analyze the dependence of the Gross Domestic Product (GDP) per capita growth rates on changes in the Corruption Perceptions Index (CPI). For the period 1999–2004 for all countries in the world, we
Lectures on Macroeconomics
Lectures on Macroeconomics provides the first comprehensive description and evaluation of macroeconomic theory in many years. While the authors' perspective is broad, they clearly state their
