We explain how to optimize portfolios of bonds and stocks with respect to the Expected Shortfall (ES), respectively RORC or RORAC based on ES. In a pragmatic approach we combine and correlate a stock market model with geometric brownian motions with a two-factor Cox-Ingersoll-Ross (CIR-2) model for the interest rates/bonds. We use recent results from the theory of risk capital allocation, perfo...

We explain how to optimize portfolios with respect to RORAC and RORC based on Expected Shortfall. Recent results from the theories of performance measurement and Swarm Intelligence are used for numeric optimization. We combine and correlate geometric Brownian motions for stocks with a two-factor Cox-Ingersoll-Ross (CIR-2) model for interest rates such that portfolios of bonds and stocks can be ...

We study a novel aspect of a firm’s capital structure, namely the profile of its debt maturity dates. In a simple theoretical framework we show that the dispersion of debt maturities constitutes an important dimension of capital structure choice, driven by firm characteristics and debt rollover risk. Guided by these results we establish two main empirical results. First, using an exogenous shoc...

I explore the role of the Just-in-Time (JIT) inventory system in the increase of cash holdings among U.S. manufacturing firms. I first demonstrate the empirical importance of JIT in shaping cash policy. I then develop a model to analyze the mechanism through which JIT affects cash and quantify its impact. In the model, both cash and inventory can serve as working capital. As firms switch from t...

We document the evolution of productivity in a steel mini mill with fixed capital, producing an unchanged product with Leontief technology working 24/7. Despite—almost—unchanged production conditions, output doubled within the sample period (12 years). We decompose the gains into downtime reductions, more rounds of production per time, and more output per run. After attributing productivity gai...

Investment-based asset pricing research highlights the role of irreversibility as a determinant of firms’ risk and expected return. In a neoclassical model of a firm with costly scale adjustment options, we show that the effect of scale flexibility (i.e., contraction and expansion options) is to determine the relation between risk and operating leverage: risk increases with operating leverage f...

This paper uses the financial crisis of 2008 as a natural experiment to demonstrate that when measuring investment-cash flow sensitivity, the value of a firm‟s assets that can be used as collateral should be taken into account. Using panel data on U.S. firms from 1990 to 2011, it was found that the share of physical capital in assets has a strong influence on investment-cash flow sensitivity, w...

This paper derives a preemptive equilibrium in strategic investment in alternative projects. The problem is formulated in a real options model with a multidimensional state variable that represents project-specific uncertainty. The proposed method enables us to evaluate the value of potential alternatives. The results not only extend previous studies with a one-dimensional state variable but al...

In the managerial myopia literature the firm always faces some agency problem or other market imperfection. It is unclear whether the myopic behavior found in these models is due to stock-based incentives or the model's other market imperfections. This paper points out that stock incentives do not lead to myopia unless they result in more emphasis on the short-term than would occur under an opt...

Our paper studies an economy in which each financial institution takes into account that if it has to sell its assets after others have already sold, the price will be lower. This causes preemptive selling, driven not by actual margin calls, but by the fear of future margin calls. Financial institutions cannot determine their optimal capitalizations in isolation, but need to know the aggregate ...
