Option pricing under incompleteness and stochastic volatility.
TLDR
In this article, the authors consider a general diffusion model for asset prices which allows the description of stochastic and past-dependent volatilities, and they show that for the purpose of pricing options, a small investor should use the minimal equivalent martingale measure associated to the underlying stock price process.Abstract:
We consider a very general diffusion model for asset prices which allows the description of stochastic and past-dependent volatilities. Since this model typically yields an incomplete market, we show that for the purpose of pricing options, a small investor should use the minimal equivalent martingale measure associated to the underlying stock price process. Then we present stochastic numerical methods permitting the explicit computation of option prices and hedging strategies, and we illustrate our approach by specific examples.read more

Stochastic processes in insurance and finance
TL;DR: In this paper, the authors dealt mainly with the application of financial pricing techniques to insurance problems, and presented that realistic models for asset price processes are typically incomplete, and that actuarial concepts for risk-management might prove helpful in dealing with these “unhedgeable” risks.

Markowitz Revisited: Mean-Variance Models in Financial Portfolio Analysis
TL;DR: The interplay between objective and constraints in a number of single-period variants, including semivariance models are described, revealing the possibility of removing surplus money in future decisions, yielding approximate downside risk minimization.

On the minimal martingale measure and the möllmer-schweizer decomposition
TL;DR: In this article, three characterizations of the minimal martingale measure [Pcirc] associated to a given d-dimensional semimartingale X are provided. And they extend the result of Ansel and Stricker on the Follmer-Schweizer decomposition to the case where X is continuous, but multidimensional.

The Pricing of Options and Corporate Liabilities
Fischer Black,Myron S. Scholes +1 more
TL;DR: In this paper, a theoretical valuation formula for options is derived, based on the assumption that options are correctly priced in the market and it should not be possible to make sure profits by creating portfolios of long and short positions in options and their underlying stocks.

An intertemporal capital asset pricing model
TL;DR: In this article, an intertemporal model for the capital market is deduced from portfolio selection behavior by an arbitrary number of investors who aot so as to maximize the expected utility of lifetime consumption and who can trade continuously in time.

Optimum consumption and portfolio rules in a continuous-time model☆
TL;DR: In this paper, the authors considered the continuous-time consumption-portfolio problem for an individual whose income is generated by capital gains on investments in assets with prices assumed to satisfy the geometric Brownian motion hypothesis, which implies that asset prices are stationary and lognormally distributed.

Lifetime Portfolio Selection under Uncertainty: The Continuous-Time Case
TL;DR: In this paper, the combined problem of optimal portfolio selection and consumption rules for an individual in a continuous-time model was examined, where his income is generated by returns on assets and these returns or instantaneous "growth rates" are stochastic.

The Pricing of Options on Assets with Stochastic Volatilities
John Hull,Alan White +1 more
TL;DR: In this article, the option price is determined in series form for the case in which the stochastic volatility is independent of the stock price, and the solution of this differential equation is independent if (a) the volatility is a traded asset or (b) volatility is uncorrelated with aggregate consumption, if either of these conditions holds, the risk-neutral valuation arguments of Cox and Ross [4] can be used in a straightfoward way.
