Estimation of operational risk capital charge under parameter uncertainty

Optimal investment under operational flexibility, risk aversion, and uncertainty

Traditional real options analysis addresses the problem of investment under uncertainty assuming a risk-neutral decision maker and complete markets. In reality, however, decision makers are often risk averse and markets are incomplete. We confirm that risk aversion lowers the probability of investment and demonstrate how this effect can be mitigated by incorporating operational flexibility in t...

Interval Technique for Parameter Estimation under Model Uncertainty

This paper is devoted to the problem of estimation of parameters for linear multioutput models with uncertain regressors and additive noise. The uncertainty is assumed to be described by intervals. Outer-bounding interval approximations of the non-convex feasible parameter set for uncertain system are obtained. The proposed method is based on the calculation of the interval solution for an inte...

Capital Structure under Changing Uncertainty

We explain the puzzle of falling firm leverage during the period of decreasing aggregate volatility from 1970 – 2010 with a simultaneous increase in firm level volatility and varying degrees of firm access to public debt markets. By incorporating friction between public and private debt, a structural model where firms make financing policy decisions in presence of uncertainty can explain a sign...

Estimation of Scale Parameter Under a Bounded Loss Function

     The quadratic loss function has been used by decision-theoretic statisticians and economists for many years.  In this paper  the estimation of scale parameter under a bounded loss function, which is adequate for assessing quality and quality improvement, is considered with restriction to the principles of invariance and risk unbiasedness. An implicit form of minimum risk scale equivariant ...
