We exploit the US Survey of Consumer Finances from 1998 to 2010 to study households' portfolio risk. We compare alternative measures of ex-ante risk, based on a financial portfolio including deposits, bonds and stocks, or a broader portfolio also including real estate, business wealth and...

Historical VaR, CVaR and ES (Expected Shortfall) to LIQUIDATION Software is a model characterized by its straightforwardness, allowing regulators measure risk using a standard database of primitive factors and portfolio positions only, leaving little error margin in comparing market risk for...

We formulate the multi-period, time consistent mean-CVAR (Conditional Value at Risk) asset allocation problem in a form amenable to numerical computation. Our numerical algorithm can impose realistic constraints such as: no shorting, no-leverage, and discrete rebalancing. We focus on long term...

Recently, a lot of attention has been focused on developing portfolio allocation models that take into account the asymmetric nature of asset return distributions. In this paper, we extend Krokhmal, Palmquist, and Uryasev's approach by using CVaR-like constraints in the traditional portfolio...

We present a model for P/L insurance companies based on Asset-Liability-Management (ALM). We show analytically for multivariate normal distributed assets and claims that an overall minimum of the required risk capital can be obtained by refining the firm's asset allocation when including a ruin...

We discuss risk measures representing the minimum amount of capital a financial institution needs to raise and invest in a pre-specified eligible asset to ensure it is adequately capitalized. Most of the literature has focused on cash-additive risk measures, for which the eligible asset is a...

We study capital requirements for bounded financial positions defined as the minimum amount of capital to invest in a chosen eligible asset targeting a pre-specified acceptability test. We allow for general acceptance sets and general eligible assets, including defaultable bonds. Since the...

In the recent Basel Accords, the Expected Shortfall (ES) replaces the Value-at-Risk (VaR) as the standard risk measure for market risk in the banking sector, making it the most popular risk measure in financial regulation. Although ES is - in addition to many other nice properties - a coherent...

In this paper, we study an optimal investment problem under joint initial-time and intermediate-time Value-at-Risk regulations and a portfolio insurance (PI) constraint on terminal wealth faced by a defined-contribution pension fund manager. The objective is to maximize the expected utility from...
