This paper presents a review of the main theories on hedging with futures contracts, and the various estimation methods used to estimate the optimum hedge ratio. The most widely used approach to hedging in the extensive literature in this field of research is unquestionably that based on the...

Identifying risk spillovers in financial markets is of great importance for assessing systemic risk and portfolio management. Granger causality in tail (or in risk) tests whether past extreme events of a time series help predicting future extreme events of another time series. The topology and...

We develop an empirically highly accurate discrete-time daily stochastic volatility model that explicitly distinguishes between the jump and continuous-time components of price movements using nonparametric realized variation and Bipower variation measures constructed from high-frequency...

In this paper we propose a model for the conditional multivariate density of integer count variables defined on the set Z^n. Applying the concept of copula functions, we allow for a general form of dependence between the marginal processes which is able to pick up the complex nonlinear dynamics...

In this paper we model the dynamic multivariate density of discrete bid and ask quote changes and their associated depths. We account for the contemporaneous relationship between these trading marks by exploiting the concept of copula functions. Thereby we show how to model truncations of the...

In this paper we develop a structural equation model with latent variables in an ordinal setting which allows us to test broker-dealer predictive ability of financial market movements. We use a multivariate logit model in a latent factor framework, develop a tractable estimator based on a...

There are three crucial mathematical system concepts in Finance, which are either being confused or misapplied - uncertainty, complexity and rank. First, the concept of epistemic uncertainty is sufficient for modeling and the concept of probability is unnecessary. This is illustrated by Galton's...

In this study, we investigate whether the characteristics of clients, auditors, and the auditor-client relationship simultaneously determine audit and non-audit fees. As done in prior studies, we maintain that fees proxy for the level of service provided and follow the physical flow of...

It is a common understanding that bankruptcy is not a sudden occurrence for any organizations. Macro and micro economic studies have suggested numerous influential factors, which have substantial evidence toward firm's performance (Bekeris, 2012) and survivability (Nehrebecka & Dzik, 2013). With...

In today's turbulent marketplace with unprecedented portfolio turnover, transition activity and drawdowns, one must identify and eliminate all sources of Sharpe ratio erosion. In this environment, trading costs and risks are significant contributors to this performance drag and avoiding them is...
