Classical quantitative finance models such as the Geometric Brownian Motion or its later extensions such as local or stochastic volatility models do not make sense when seen from a physics-based perspective, as they are all equivalent to a negative mass oscillator with a noise. This paper...

In this paper we propose a Lagrange multiplier test for volatility interactions among markets or assets. The null hypothesis is the Constant Conditional Correlation GARCH model in which volatility of an asset is described only through lagged squared innovations and volatility of its own. The...

We construct a network volatility index (NetVIX) via market interconnectedness and volatilities to measure global market turbulence. The NetVIX multiplicatively decomposes into an average volatility and a network amplifier index. It also additively decomposes into marginal volatility indices for...

In this paper we develop a method for testing the implications of the Bernanke-Blinder model for monetary policy transmission. Multivariate cointegration techniques are used in a sample that includes six major industrial countries with data covering the last 25 years. Moreover, we examine...

We propose measures of financial market stress for forty-six countries and regions across the world. Our measures indicate that worldwide financial market stresses rose significantly in March following the widespread economic shutdowns in the wake of the COVID-19 pandemic. However, hardly...

This paper investigates the power of macroeconomic factors to explain euro area bond risk premia using (i) a big dataset (ii) the Elastic Net variable selection. We find that macroeconomic factors, in particular economic activity and sentiment indicators, explain 40% of the variability of risk...

This study investigates the impact of price limits and trading halts (circuit breakers) on the returns volatility of the Nigerian equity markets during the market meltdown occasioned by the Global Financial and Economic Crises of 2007-2010. Results indicate that the introduction of price limits...

This paper investigates the power of macroeconomic factors to explain euro area bond risk premia using (i) a large dataset that captures the nowadays data-rich environment (ii) the Elastic Net variable selection. We find that macroeconomic factors, in particular economic activity and sentiment...
