After the collapse of the housing bubble in 2007, severe fire sales of assets in the financial sector are accompanied by a rise in the volatility of asset returns in the non-financial firms. To account for their co-movements, I develop a model that highlights the interaction between the financial health of the banking sector and the volatility of asset returns. The novel feature of the model is...

It is a well-known fact that financial returns exhibit conditional heteroscedasticity and fat tails. While the GARCH-type models are very popular in depicting the conditional heteroscedasticity, the α-stable distribution is a natural candidate for the conditional distribution of financial returns. The α-stable distribution is a generalization of the normal distribution and is described by four ...

The Value-at-Risk (VaR) approach has been extensively used for measuring and controlling of market risks in financial institutions during the last decade. The risk control and management systems required in the new banking industry are based on the Banks for International Settlements’ (BIS) suggestions. Financial asset returns are traditionally modeled as being distributed according to the norm...

A recent study by Hong and Kazperczyk (2005) finds that sin stocks – publicly-traded stocks in the gaming, tobacco, and alcohol industries are neglected by the stock market despite generating abnormal stock returns. We examine a rational explanation for their findings. Are the excess returns and investor neglect of sin stocks attributable to higher levels of information risk arising from poor f...

Entrepreneurship has positive externalities, but innovators face borrowing constraints and require the services of financiers in order to invest efficiently. When investment and education subsidies are chosen...

this paper uses a multivariate garch model to simultaneously estimate the mean and conditional variance using daily returns among different tehran sector indexes from tir 1386 to tir 1391. since different financial assets are traded based on these sector indexes, it is important for financial market participants to understand the volatility transmission mechanism over time and across sectors in...
