We consider semiparametric frequency domain analysis of cointegration between long memory processes, i.e. fractional cointegration. This concept allows derivation of useful long-run relations even among stationary long memory processes. The approach uses a degenerating part of the periodogram...

The paper proposes a general asymmetric multifactor Wishart stochastic volatility (AMWSV) diffusion process which accommodates leverage, feedback effects and multifactor for the covariance process. The paper gives the closed-form solution for the conditional and unconditional Laplace transform...

We study the effect of going-concern contingent capital on bank risk choice. The possibility of debt for equity conversion forces deleveraging in highly levered states, when risk incentives are worse. The additional equity reduces endogenous risk shifting by diluting returns in high states. An...

Credit risk models should reflect the observation that the relevant value of collateral is generally not the average value of the asset over all possible states of nature. In most cases, the relevant value of collateral for the lender is its secondary market value in bad states of nature, where...

Building on a model of the interaction of risk-averse frms that compete in forward and spot markets, we develop an empirical strategy to test whether oligopolistic frms use forward contracts for strategic motives, for risk-hedging, or for both. An increase in the number of players weakens the...

Taking a portfolio perspective on option pricing and hedging, we show that within the standard Black-Scholes-Merton framework large portfolios of options can be hedged without risk in discrete time. The nature of the hedge portfolio in the limit of large portfolio size is substantially different...

There has recently been growing interest in modeling and estimating alternative continuous time multivariate stochastic volatility models. We propose a continuous timefractionally integrated Wishart stochastic volatility (FIWSV) process. We derive the conditional Laplace transform of the FIWSV...

This study examines the key drivers of sovereign default risk in five euro area periphery countries and three euro-candidates that are currently pursuing independent monetary policies. We argue that the recent proliferation of sovereign risk premiums stems from both domestic and international...

This paper applies an alternative model to analyze criminal behaviour by countries based on real option models. Criminal options incorporate a richer framework than traditional cost-benefit models and allow examining the optimal timing of a crime as criminals have the possibility but not the...
