I examine the impact of financial sector stress on risk sharing in a novel setting: the CME's weather derivatives … financial sector stress, the risk premium on futures and implied volatility of options increase significantly. The effects are … greatest for high margin and high total risk contracts. Consistent with a decline in the supply of financial capital during …

The main aim of the thesis is to formulate a concept of liquidity risk and to incorporate liquidity risk in market risk … measurement. We first review two types of liquidity risk and the relation between liquidity risk and market risk. To achieve our … valuation includes a consideration of liquidity risk in portfolio valuation. Under the new framework, the valuation of a …

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 subclass of them: spectral measures of risk. Expected shortfall is a well …

We investigate the dynamics of the relationship between returns and extreme downside risk in different states of the … market by combining the framework of Bali, Demirtas, and Levy (2009) with a Markov switching mechanism. We show that the risk … periods of market turbulence. This is puzzling since it is during such periods that downside risk should be most prominent. We …

We use an empirical model to categorize firms into portfolios based on operational risk. Using these portfolios, we … show that a strategy of buying firms in the highest decile of operational risk and shorting firms in the lowest decile of … operational risk earned a positive but insignificant risk-adjusted average return of 0.72% per month from 1990 to 2000. However …

We examine the puzzling negative relation between financial distress risk and the cross-section of expected returns. We … most recent distress risk shocks to which investors initially underreact, causing temporary overpricing of distressed … stocks. In the long run, the relation between distress risk and returns reflects the positive risk premium as distress risk …

We propose new systematic tail risk measures constructed using two different approaches. The first extends the … market crash risk. Both tail risk measures are associated with a significantly positive risk premium after controlling for … other measures of downside risk, including downside beta, co-skewness and co-kurtosis. Using these measures, we examine the …

Standard risk management approaches fail to consider parameter uncertainty, which has led to improper risk management …

This paper proposes a risk measure, based on first-passage probability, which reflects intra-horizon risk in jump … models with finite or infinite jump activity. Our empirical investigation shows, first, that the proposed risk measure … consistently exceeds the benchmark Value-at-Risk (VaR). Second, jump risk tends to amplify intra-horizon risk. Third, we find large …
