Portfolio Similarity and Asset Liquidation in the Insurance Industry
(2018-07-30)
An important assumption underlying the designation of some insurers as systemically important is that their overlapping portfolio holdings can result in common selling. We measure the overlap in holdings using cosine ...
Networks in Risk Spillovers: A Multivariate GARCH Perspective
(2018-08-01)
We propose a spatiotemporal approach for modeling risk spillovers using time-varying proximity matrices based on observable financial networks and introduce a new bilateral specification. We study covariance stationarity ...
Idiosyncratic Volatility Puzzle: The Role of Assets' Interconnections
(2018-08-08)
The paper investigates the determinants of the idiosyncratic volatility puzzle by allowing linkages across asset returns. The first contribution of the paper is to show that portfolios sorted by increasing indegree computed ...
The Pitfalls of Central Clearing in the Presence of Systematic Risk
(2018-11-08)
Asset transaction prices sampled at high frequency are much staler than one might expect in the sense that they frequently lack new updates showing zero returns. In this paper, we propose a theoretical framework for ...
Statistical Inferences for Price Staleness
(2018-11-06)
Asset transaction prices sampled at high frequency are much staler than one might expect in the sense that they frequently lack new updates showing zero returns. In this paper, we propose a theoretical framework for ...
High-Dimensional Sparse Financial Networks through a Regularised Regression Model
(2019-02-12)
"We propose a shrinkage and selection methodology specifically designed for network inference using high dimensional data through a regularised linear regression model with Spike-and-Slab prior on the parameters. The ...
Life Insurance and Demographic Change: An Empirical Analysis of Surrender Decisions Based on Panel Data
(2016-12-01)
Households buy life insurance as part of their liquidity management. The option to surrender such a policy can serve as a buffer when a household faces a liquidity need. In this study, we investigate empirically which ...
Professional Networks and their Coevolution with Executive Careers: Evidence from Europe and North America
(2019-02-04)
This paper examines how networks of professional contacts contribute to the development of the careers of executives of North American and European companies. We build a dynamic model of career progression in which career ...
Belief Formation and Belief Updating under Ambiguity: Evidence from Experiments
(2019-09-21)
Decisions under ambiguity depend on both the belief regarding possible scenarios and the attitude towards ambiguity. This paper exclusively focuses on beliefs, measured independent from attitudes. We use laboratory experiments ...
The Case for a Normatively Charged Approach to Regulating Shadow Banking - Multipolar Regulatory Dialogues as a Means to Detect Tail Risks and Preclude Regulatory Arbitrage
(2020-02-11)
This paper contributes to the debate on the adequate regulatory treatment of non-bank financial intermediation (NBFI). It proposes an avenue for regulators to keep regulatory arbitrage under control and preserve sufficient ...
