Meta-analysis has increasingly been used to synthesise the environmental valuation literature, but only a few test the use of these analyses for benefit transfer. These are typically based on national studies only. However, meta-analyses of valuation studies across countries are a potentially powerful tool for benefit transfer, especially for environmental goods where the domestic literature is...

Development of downstream operations in the Iran's petroleum industry has always been considered as a necessity in to create more value-added. One of ways to accomplish the misson, especially in the current situation, is exploiting the capacity of petroleum startups. Considering that these companies need to be valued for financing, and since the traditional valuation methods do not provide effi...

The stochastic Alpha Beta Rho stochastic volatility (SABR-SV) model is widely used in the financial industry for the pricing of fixed income instruments. In this paper we develop an unbiased simulation scheme for the SABR-SV model, which deals efficiently with (undesired) possible negative values, the martingale property of the discrete scheme and the discretization bias of commonly used Euler ...

Proposition algebra is based on Hoare’s conditional connective, which is a ternary connective comparable to if-then-else and used in the setting of propositional logic. Conditional statements are provided with a simple semantics that is based on evaluation trees and that characterizes so-called free valuation congruence: two conditional statements are free valuation congruent if, and only if, t...

The brand is a very special asset and in many businesses it is the most important asset. This is due to the farreaching economic impact that brands have on enterprise. Brands influence the choice of customers, employees, investors and government authorities. In a world of abundant choices such influence is crucial for commercial success and creation of shareholder value. Even non-profit organis...

let r be a ring and v be a matrix valuation on r. it is shown that, there exists a correspondence between matrix valuations on r and some special subsets ?(mvpr) of the set of all square matrices over r, analogous to the correspondence between invariant valuation rings and abelian valuation functions on a division ring. furthermore, based on malcolmson’s localization, an alternative proof for t...
