Designing Minimum-Risk Nonlinear Price Schedules for Water Utilities
Water Utilities Nonlinear Price Schedules
2015/7/31
This paper formulates and estimates a household-level demand for water under increasing
block prices that accounts for the impact of monthly weather variation and customer-level
heterogeneity in d...
On absolutely continuous compensators and nonlinear filtering equations in default risk models
Azema supermartingale default indicator absolutely continuous compensators pricing of default risk nonlinear filtering
2012/6/5
We discuss the pricing of defaultable assets in an incomplete information model where the default time is given by a first hitting time of an unobservable process. We show that in a fairly general Mar...
In this paper we introduce a simple continuous-time asset pricing framework, based on general multidimensional diffusion processes, that combines semi-analytic pricing with a nonlinear specification f...
Study of the risk-adjusted pricing methodology model with methods of Geometrical Analysis
transaction costs invariant reductions exact solutions singular perturbation
2010/11/2
Families of exact solutions are found to a nonlinear modification of the Black-Scholes equation. This risk-adjusted pricing methodology model (RAPM) incorporates both transaction costs and the risk fr...
We apply a quadratic hedging scheme developed by Follmer, Schweizer, and Sondermann to
European contingent products whose underlying asset is modeled using a GARCH process and show
that local risk-...
Risk-neutral and Physical Jumps in Option Pricing
Option Pricing price dynamics physical jumps
2011/4/6
When jumps are present in the price dynamics of the underlying asset, the market is no longer complete, and a more general pricing framework than the risk-neutral valuation is needed. Using Monte Carl...
