Exploring Financial Networks Using Quantile Regression and Granger Causality

  title={Exploring Financial Networks Using Quantile Regression and Granger Causality},
  author={Kara Karpman and Samriddha Lahiry and Diganta Mukherjee and Suman Basu},
In the post-crisis era, financial regulators and policymakers are increasingly interested in data-driven tools to measure systemic risk and to identify systemically important firms. Granger Causality (GC) based techniques to build networks among financial firms using time series of their stock returns have received significant attention in recent years. Existing GC network methods model conditional means, and do not distinguish between connectivity in lower and upper tails of the return distribution…

Learning Financial Networks with High-frequency Trade Data

Financial networks are typically estimated by applying standard time series analyses to price-based economic variables collected at low-frequency (e.g., daily or monthly stock returns or realized



Regression Shrinkage and Selection via the Lasso

A new method for estimation in linear models called the lasso, which minimizes the residual sum of squares subject to the sum of the absolute value of the coefficients being less than a constant, is proposed.

We provide a concise overview of time series analysis in the time and frequency domains, with lots of references for further reading.

Econometric Measures of Connectedness and Systemic Risk in the Finance and Insurance Sectors

We propose several econometric measures of connectedness based on principal-components analysis and Granger-causality networks, and apply them to the monthly returns of hedge funds, banks,

Quantile Autoregression

We consider quantile autoregression (QAR) models in which the autoregressive coefficients can be expressed as monotone functions of a single, scalar random variable. The models can capture systematic

A System-Wide Approach to Measure Connectivity in the Financial Sector

We develop and estimate a measure of network connectivity for a sample of very large financial institutions of the U.S. Our model takes a system-wide approach that explicitly recognizes the

In this paper we derive the asymptotic distribution of the least absolute deviations (LAD) estimator of the autoregressive parameter under the unit root hypothesis, when the errors are assumed to

Asymptotics for Least Absolute Deviation Regression Estimators

The LAD estimator of the vector parameter in a linear regression is defined by minimizing the sum of the absolute values of the residuals. This paper provides a direct proof of asymptotic normality
