We introduce an asset-allocation framework based on the active control of the value-at- risk of the portfolio. Within this framework, we compare two paradigms for making the allocation using neural networks. The first one uses the network to make a forecast of asset behavior, in conjunction with...

The recent financial crisis has led to a critical evaluation of the role that fair value accounting may have played in undermining the stability of the financial system. Reacting to the pressures of banking regulators and governments, standard-setters have brought forward additional guidance on...

Using a unique proprietary dataset of primary insurers and reinsurers, we analyze the structure of the reinsurance market. The dataset, which spans six years, contains the quotes for different reinsurance layers, for different clients, for different treaties, and for different lines of business....

We characterize a firm as a nexus of activities and projects with their associated cash flow distributions across states of the world and time periods. We propose a characterization of the firm where variations in the market price of risk induce adjustments in the value-maximizing combination of...

This paper examines the impact of capital structure on the optimality of contingent financial contracts. The role of financial relationships is not only to provide funds but also to offer insurance to a risk adverse entrepreneur through contingent financial transfers. Since such financial...

Stochastic volatility models, aka SVOL, are more difficult to estimate than standard time-varying volatility models (ARCH). Advances in the literature now offer well tested estimators for a basic univariate SVOL model. However, the basic model is too restrictive for many economic and finance...

Value-at-Risk (VaR) has emerged as the standard tool for measuring and reporting financial market risk. Currently, more than eighty commercial vendors offer enterprise or trading risk management systems which report VaR-like measures. Risk managers are therefore often left with the daunting task...

We characterize a firm as a nexus of activities and projects with their associated cashflows. Production and operations activities and real risk management activities distribute cashflows over states of nature and time periods, leading to a transformation possibility frontier similar to a...

Did fair value accounting play a role in the current financial crisis? This appendix explores the issue. Fair value accounting implies that assets and liabilities get measured and reflected on a firm`s financial statements at their market value, or close substitutes. Extensive academic research...
