One important source of systemic risk can arise from asset commonality among financial institutions. This indirect interconnection may occur when financial institutions invest in similar or correlated assets and it is also described as overlapping portfolios. In this paper, we propose a new...

White et al. (2015) extend the vector autoregressive (VAR) for conditional mean to VAR for conditional quantiles (VAR-VaR) to capture the interdependencies among the quantiles of multiple time series. In this paper, we introduce a post-lasso estimator to extend VAR-VaR to the high-dimensional...

Employing a generalized Hamiltonian Monte Carlo Bayesian procedure we develop a new measure of real estate uncertainty that explicitly encapsulates conditional stochastic volatility and noise. When applied to commercial real estate (CRE) markets, results of Vector Autoregressive (VAR) modeling...

The industry is currently seeking to evolve collateral models based on Value-at-Risk to include Wrong-Way-Risk (WWR) add-ons. A parallel trend is to require risk managers to possess Reverse Stress Testing (RST) tools to identify extreme but plausible scenarios and hedge them pro-actively. Use...

This paper offers a detailed investigation of the foreign exchange risk premium using a structural relationship in the inflation-index bond market, firstly introduced by Clarida (2012). Unlike the conventional VAR approach, this approach estimates risk premium through the non-arbitrage...

We propose a heterogeneous autoregressive (HAR) model with time-varying parameters in the form of a local linear random forest. In contrast to conventional random forests that approximate the volatility nonparametrically using local averaging, the building blocks of our forest are HAR panel...

We study graphon mean-field backward stochastic differential equations (BSDEs) with jumps and associated dynamic risk measures. We establish the existence, uniqueness and measurability of solutions under some regularity assumptions. For an interacting mean-field particle system with...
