A conditional asset pricing model with risk and uncertainty implies that the time-varying exposures of equity portfolios to the market and uncertainty factors carry positive risk premiums. The empirical results from the size, book-to-market, and industry portfolios as well as individual stocks...

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...

In financial economics, numerous theoretical models explain the relationship between investment risk and return in the capital market, one of the most common being the Capital Asset Pricing Model (CAPM). After reviewing the literature in this area, this study discusses the theoretical background...

When people share risk in financial markets, intermediaries provide costly enforcement for most trades and, hence, are an integral part of financial marketsu0092 organization. We assess the degree of risk sharing that can be achieved through financial markets when enforcement is based on the...

We analyse the relationships between return calculation methods, risk and observation periods. We show that the mean of a return set calculated using logarithmic returns is less than the mean calculated using simple returns by an amount related to the variance of the set. This implies that there...

We consider the optimal asset allocation choice of an investor who can invest in <p> cash (a money market bank account), nominal bonds, and stocks (the stock index). <p> The investor faces an incomplete market setting and is not able to perfectly hedge <p> long run real interest rate risk using the...</p></p></p>

This article reviews the principal features of structured finance instruments. Key to understanding the risk properties of these products is the evaluation of the risks associated with their contractual structure, in addition to the modelling of the credit risk of the underlying asset pools. It...

Coherent measures of risk defined by the axioms of monotonicity, subadditivity, positive homogeneity, and translation invariance are recent tools in risk management to assess the amount of risk agents are exposed to. If they also satisfy law invariance and comonotonic additivity, then we get a...

We investigate the relationship between bankruptcy risk and expected future sales growth for Norwegian non-listed firms for the period 1988-2007. We find that firms with high bankruptcy risk also have high expected future growth. Financial ratios characterizing firms with high bankruptcy risk...

This study is motivated by the fact that the financial sector has been mandated to support political decisions promoting sustainable development. For the banking sector, ESG (environmental, social and governance) risks constitute a new source of risks which should be identified, evaluated,...
