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 on the network based on Granger causality test have lower expected...

This paper extends the classic factor-based asset pricing model by including network linkages in linear factor models. We assume that the network linkages are exogenously provided. This extension of the model allows a better understanding of the causes of systematic risk and shows that (i)...

This paper analyses whether the post-crisis regulatory reforms developed by globalstandard- setting bodies have created appropriate incentives for different types of market participants to centrally clear Over-The-Counter (OTC) derivative contracts. Beyond documenting the observed facts, we...

This paper is a first attempt at empirically analyzing whether post-crisis regulatory reforms have created appropriate incentives to voluntarily centrally clear Over-The-Counter (OTC) derivative contracts. We use confidential European trade repository data on singlename sovereign Credit...

This paper empirically analyses whether post-global financial crisis regulatory reforms have created appropriate incentives to voluntarily centrally clear the over-the-counter (OTC) derivative contracts. We use confidential European trade repository data on single-name sovereign credit default...
