Liquidity and market risk are key considerations in financial markets, especially in times of financial crises. For this reason, regulatory attention to and measures in these fields have been on the rise for the past years. Based on practical experience, regulations aiming at ensuring funding...

When institutional investors rearrange their portfolios, they should consider both the temporary and the permanent price impacts. After a temporary price impact the order book fully recovers, whereas a permanent price impact changes the equilibrium price, having effects on the resulting...

Let us consider a financially constrained leveraged financial firm having some divisions which have invested into some risky assets. Using coherent measures of risk the sum of the capital requirements of the divisions is larger than the capital requirement of the firm itself, there is some...

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...

The most important rule to determine payments in real-life bankruptcy problems is the proportional rule. Many bankruptcy problems are characterized by network aspects and default may occur as a result of contagion. Indeed, in financial networks with defaulting agents, the values of the agents'...

We introduce a dynamic principal-agent model to understand the nature of contracts between an employer and an independent gig worker. We model the worker’s self-respect with an endogenous participation constraint; he accepts a job offer if and only if its utility is at least as large as his...

The measurement and the allocation of risk are fundamental problems of portfolio management. Coherent measures of risk provide an axiomatic approach to the former problem. In an environment given by a coherent measure of risk and the various portfolios' realization vectors, risk allocation games...
