In recent decades, concerns have arisen about the proper valuation of the world's forests. While some of these concerns have to do with market distortions for timber products or inadequate data on non-timber forest products, an additional issue has been the challenge of uncovering the economic worth of non-market services provided by forest ecosystems (Kramer, Healy and Mendelsohn). This has le...

The National Oceanic and Atmospheric Administration Contingent Valuation panel recommended that a response category be included along with the vote in favor and vote against options associated with a referendum contingent valuation question that allows individuals to express lack of a well defined opinion.

We propose a new methodology for the valuation problem of financial contingent claims when the underlying asset prices follow a general class of continuous Itô processes. Our method can be applicable to a wide range of valuation problems including contingent claims associated with stocks, foreign exchange rates, the term structure of interest rates, and even their combinations. We illustrate ou...

The over-exploited groundwater resources on the North China Plain have caused ecological problems, including lowering of the groundwater table, enlarging the depression zone and land subsidence. The contingent valuation method, a technique that reveals peoples’ preferences, is applied to measure the in situ value of groundwater in order to provide policy makers information on protection and res...

We discuss the valuation of credit derivatives in extreme regimes such as when the time-tomaturity is short, or when payoff is contingent upon a large number of defaults, as with senior tranches of collateralized debt obligations. In these cases, risk aversion may play an important role, especially when there is little liquidity, and utility indifference valuation may apply. Specifically, we an...

In a Markovian stochastic volatility model, we consider financial agents whose investment criteria are modelled by forward exponential performance processes. The problem of contingent claim indifference valuation is first addressed and a number of properties are proved and discussed. Special attention is given to the comparison between the forward exponential and the backward exponential utilit...
