Empirical Models of Imperfect Competition: A Discussion
Auction entry price competition estimation
2015/7/17
The field of Industrial Organization (IO) studies the behavior of firms and the interaction among
them. In the last 25 years, IO studies have increasingly focused on single industries, us...
New solvable stochastic volatility models for pricing volatility derivatives
New solvable stochastic volatility models pricing volatility derivatives Pricing of Securities
2012/6/5
Classical solvable stochastic volatility models (SVM) use a CEV process for instantaneous variance where the CEV parameter $\gamma$ takes just few values: 0 - the Ornstein-Uhlenbeck process, 1/2 - the...
Exponential Levy models with stochastic volatility and stochastic jump-intensity
spectral theory normal operator Levy process stochastic volatility stochastic jump-intensity
2012/6/4
We consider the problem of valuing a European option written on an asset whose dynamics are described by an exponential L\'evy-type model. Both the volatility and jump-intensity of the L\'evy process ...
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...
Local Volatility Pricing Models for Long-dated FX Derivatives
Local volatility Stochastic volatility Foreign Exchange Stochastic interest rates Calibration
2012/4/28
We study the local volatility function in the Foreign Exchange market where both domestic and foreign interest rates are stochastic. This model is suitable to price long-dated FX derivatives. We deriv...
Volatility forecasts and the at-the-money implied volatility: a multi-components ARCH approach and its relation with market models
Volatility forecasts at-the-money implied relation
2010/10/29
For a given time horizon T, this article explores the relationship between the realized volatility (the volatility that will occur between t and t + T), the implied volatility (corresponding to at-t...
Stochastic Volatility Models Including Open, Close, High and Low Prices
Stochastic Volatility Models Prices
2010/10/29
Mounting empirical evidence suggests that the observed extreme prices within a trading
period can provide valuable information about the volatility of the process within that period. In this paper we...
