Are Bubbles Bad? Is a Higher Debt Target for the Eurozone Desirable?
TLDR
In this paper, the authors show that from a structural point of view, bubbles, Pay-As-You-Go pensions, and sovereign debt are perfect substitutes for short-run fluctuations in investment.Abstract:
Bubbles are usually viewed as a threat to financial stability. This paper takes a more nuanced view. The world economy is going through an episode of Secular Stagnation, where the equilibrium rate of return on capital r is below the growth rate of the economy g. As is well-known, rational bubbles are sustainable when r ≤ g in a steady-state equilibrium. Bubbles can then implement a dynamically efficient equilibrium. We show that from a structural point of view, bubbles, Pay-As-You-Go pensions, and sovereign debt are perfect substitutes. However, when dealing with unexpected short-run fluctuations in investment, sovereign debt is far more efficient than bubbles in shifting consumption over time and in risk-sharing between generations. An increase in sovereign debt is, therefore, an efficient response to Secular Stagnation. Instead, the current Stability and Growth Pact for the eurozone embarks on an opposite course.

Heterogeneity in the debt-growth nexus: Evidence from EMU countries
TL;DR: In this paper, the authors examine whether the threshold beyond which a public debt change may have a detrimental effect on economic growth changes across euro area countries during the 1961-2015 period in contrast with previous studies, they do not use panel estimation techniques, but implement a time-series analysis for each country based on the growth literature.

Coping with the effects of population ageing on public finances in the European Union and China
TL;DR: In this article, the authors compare the challenges in the European welfare states and China and show that the challenges are qualitatively similar in the EU and China, but the quantitative picture is different: GDP per capita in China is about 30% of that in the more advanced states of the EU, and the ageing-related public expenditures as a percentage of GDP is currently one quarter of this ratio in China.

An Exact Consumption-Loan Model of Interest with or without the Social Contrivance of Money
TL;DR: This article developed the equilibrium conditions for a rational consumer's lifetime consumption-saving pattern, a problem more recently given by Harrod the useful name of "hump saving" but which Landry, Bbhm-Bawerk, Fisher, and others had touched on long before my time.

Domestic Saving and International Capital Flows
TL;DR: In this paper, the authors analyzed the international capital market and analyzed a wide range of issues including the nation's optimal rate of saving and the incidence of tax changes and found that saving that originates in a country remains 'to be invested there'.

Debt, Deficits and Finite Horizons
TL;DR: In this article, the effects of the horizon index on the steady state interest rate and the dynamic effects of government deficit finance on the economic system were investigated and a simple analytical model was developed in which the horizon of agents is a parameter which can be chosen arbitrarily.

Asset bubbles and overlapping generations
TL;DR: In this article, the authors consider the interaction between productive and nonproductive savings in a growing economy and employ an overlapping generations model with capital accumulation and various types of rents, and give necessary and sufficient conditions for the existence of an aggregate bubble.
