The following stochastic volatility model for the stock price dynamic in an incomplete market was introduced by Heston in . Under a Risk-Neutral probabilityit writes:. Here and are two standard Brownian motions under the probability measure.
An Asian option or average value option is a special type of option contract. For Asian options the payoff is determined by the average underlying price over some pre-set period of time. This is different from the case of the usual European option and American optionwhere the payoff of the option contract depends on the price of the underlying instrument at exercise; Asian options are thus one of the basic forms of exotic options.
All these methods involve some tradeoffs between numerical accuracy and computational efficiency. This example also demonstrates how variations in spot prices, volatility, and strike prices affect option prices on European Vanilla and Asian options. Asian options are securities with payoffs that depend on the average value of an underlying asset over a specific period of time.

Background and objectives : Governments in Asia Pacific APAC are increasingly using pharmaceutical pricing strategies to contain rising healthcare costs. The objective of this narrative review is to discuss formal pricing strategies for reimbursed prescription medication in APAC, supported by relevant examples of implementation differences across countries. In the discussion section, we examine key advantages and disadvantages of each strategy.
It is considered "exotic" in the sense that the pay-off is a function of the underlying asset at multiple points throughout its lifetime, rather than just the value at expiry. An Asian option actually utilises the mean of the underlying asset price sampled at appropriate intervals as the basis for its pay-off, which is where the "path-dependency" of the asset comes from. The name actually arises because they were first devised in in Tokyo as options on crude oil futures.
An Asian option or average option is a special type of option contract where the payoff depends on the average price of the underlying asset over a certain period of time. The payoff is different from the case of a European option or American option, where the payoff of the option contract depends on the price of the underlying stcok at exercise date. Asian options allow the buyer to purchase or sell the underlying asset at the average price instead of the spot price.
