We consider a model of active asset management in which mutual fund managers exert unobservable effort to earn excess returns. Investors allocate capital to both actively managed funds and passively managed products (e.g., index funds or ETFs). In the model's equilibrium, investors are...

Im Jahr 2004 wurde erstmals Mezzanine-Kapital in Form von Genussscheinen verbrieft und an mittelständische Unternehmen vergeben. Viele Mittelständler nahmen, durch ihre Wachstumspläne beflügelt, das als wirtschaftliches Eigenkapital zählende Mez-zanine-Kapital zu sehr günstigen Konditionen...

Risk management technology applied to high dimensional portfolios needs simple and fast methods for calculation of Value-at-Risk (VaR). The multivariate normal framework provides a simple off-the-shelf methodology but lacks the heavy tailed distributional properties that are observed in data. A...

We argue that active management's popularity is not puzzling despite the industry's poor track record. Our explanation features decreasing returns to scale: As the industry's size increases, every manager's ability to outperform passive benchmarks declines. The poor track record occurred before...

A flexible framework for the analysis of tail events is proposed. The framework contains tail moment measures that allow for Expected Shortfall (ES) estimation. Connecting the implied tail thickness of a family of distributions with the quantile and expectile estimation, a platform for risk...

This paper incorporates risk-based margin requirements into portfolio liquidation procedures in a novel fashion. The approach is analytic and, as a result, more efficient than conventional numerical liquidation methods. The margin requirement calculation is a self-contained inner optimization...

This paper investigates the managing strategies of a bank's liquidity reserve in the broader context of the role of asset-liability management according to the liquidity issues of a banking organisation. Several types of liquidity are presented and how these are interconnected and how they might...

We propose a model that delivers endogenous variations in term spreads driven primarily by banks’ portfolio decision and their appetite to bear the risk of maturity transformation. We first show that fluctuations of the future profitability of banks’ portfolios affect their ability to cover...
