The article examines causal relationships between sovereign credit default swaps (CDS) prices for the BRICS and most important EU economies (Germany, France, the UK, Italy, Spain) during the European debt crisis. The cross-correlation function (CCF) approach used in the research distinguishes...

This paper investigates the sources of macrofinancial fluctuations and turbulence within the framework of an approximate linear dynamic stochastic general equilibrium model of the world economy, augmented with structural shocks exhibiting potentially asymmetric generalized autoregressive...

This paper documents the theoretical structure and empirical properties of the latestversion of the Global Macrofinancial Model (GFM). This dynamic stochastic generalequilibrium model of the world economy, disaggregated into forty national economies,was developed to support multilaterally...

This paper presents a tractable model of non-linear dynamics of market returns using a Langevin approach.Due to non-linearity of an interaction potential, the model admits regimes of both small and large return fluctuations. Langevin dynamics are mapped onto an equivalent quantum mechanical (QM)...

We develop the concept of “dragon-kings” corresponding to meaningful outliers, which are found to coexist with power laws in the distributions of event sizes under a broad range of conditions in a large variety of systems. These dragon-kings reveal the existence of mechanisms of...

We assess the sustainability of the public finances of Greece, Ireland, Italy, Portugal and Spain (GIIPS), allowing for possible non-linearities in the form of threshold behaviour of the fiscal authorities. We provide some evidence of fiscal sustainability when debt gets "too high" relative to a...

The Global Financial Crisis (GFC) has rekindled debate about the desirability of governmental interference in asset markets . either through the operation of policy levers, or, through the chosen institutional setup. In this paper we quantify economic costs due to mispricing of real assets in...

The USAGE model for the United States is used to quantify economic costs due to stock mispricing, made operational by shocking Tobin’s q. The simulations quantify a potentially large impact even in the most favorable environment, where export demand holds up, and, the dollar is pro-cyclical. A...
