This paper proposes a new ‘World Volatility Index’, coined WVIX, by constructing the first index that approximates the aggregate volatility level of the G20 countries. The empirical analysis makes use of the factor dynamic conditional correlation model – with an automated methodology to...

In this paper, we investigate the interactions between public debt and transfer policies in a framework based on Floden [2001], that we extend to allow for transitional dynamics between steady states. First, we show that, starting from a high level of public debt, it is possible to implement a...

Cette étude présente une méthode empirique simple permettant d'évaluer l'impact des finances publiques sur la croissance à court terme, et plus précisément : a)l'impulsion discrétionnaire des finances publiques avant bouclage macroéconomique ; b) l'impact sur la croissance de...

With population ageing, fiscal consolidation has become of paramount importance for euro area countries. Consolidation can be pursued in various ways, with different effects on potential growth, which itself will be dragged down by ageing. A dynamic general equilibrium model with overlapping...

This paper reconsiders the impact of public debt in an economy with heterogeneous households and incomplete markets to emphasize the short-run effects of an increase in public debt. As compared to models that rest on steady-state analysis, we show that the welfare gains of a public debt increase...

This article uses graph theory to provide novel evidence regarding market integration, a favorable condition for systemic risk to appear in. Relying on daily futures returns covering a 12-year period, we examine cross- and intermarket linkages, both within the commodity complex and between...

We examine the impact, on commodity derivative markets, of two financial crises: the Subprime crisis and the bankruptcy of Lehman Brothers. These crises are "external" for commodity markets: they appeared in the financial sphere. Still, because now commodity markets are highly integrated,...

This chapter summarizes several empirical studies in finance, undertaken through the prism of the graph theory. In these studies, we built graphs in order to investigate integration and systemic risk in derivative markets. Several classes of underlying assets (i.e. energy products, metals,...

Several assessments of vulnerability and resilience have been attempted at a country level through composite indices but they are barely in accord with a holistic view of sustainable development. We suggest graph theory to structure a network of variables that depict vulnerability and resilience...
