We build a model of worker interdependence in which two workers can either compete or cooperate and compare performance under either scenario to that of a single worker working in isolation. We show that whilst competition unequivocally reduces performance, cooperation may raise or lower...

The structure of links between realized volatility and trading volume can be reflected by regime switching copulas. The estimation by means of copula based regime switching models delivered results concerning the interdependencies between realized return volatility and trading volume of selected...

Value at Risk plays a crucial role in the risk management. However, this risk measure has some drawbacks. The alternative risk measure is Expected Shortfall, which is rarely used, but exhibits desirable properties. In the paper, the estimation of both risk measures has been conducted, for pairs...
