The relationship between IT and value is complex and often disputed. Researchers and practitioners have created numerous models and valuation methods to capture this value. Although payoffs from IT investment are a function of strategic alignment, most of these models do not address the alignment of business and IT as a factor that influences or creates value. This paper explores the role of bu...

In this paper we examine the structure of American option valuation problems and derive the analytic valuation formulas under general underlying security price processes by an alternative but intuitive method. For alternative diffusion processes, we derive closed-form analytic valuation formulas and analyze the implications of asset price dynamics on the early exercise premiums of American opti...

Storage of electricity has become increasingly important, due to the gradual replacement fossil fuels by more variable and uncertain renewable energy sources. In this paper, we provide details on how mathematically formalize a corresponding storage contract, taking into account physical limitations facility operational constraints grid. We give valuation technique price these contracts, where p...

This study extends the joint estimation of revealed and stated preference data literature by accounting for truncation in the revealed preference data. The analytical model and estimation procedure are used to estimate the value of recreational red snapper fishing in the Gulf of Mexico. This recreational red snapper valuation is decomposed into its direct and indirect components. As expected, t...

Grasslands provide a variety of goods and services that benefit humans, but only few have market value. Despite the benefits provided, native grasslands continue to be degraded. Lack proper valuation, including monetary value grassland nonmarket services, has become one factors contributing degradation trend. The objective this research was quantify cost increasing provision ecosystem from ecos...

By taking case resource management Central Lombok Indonesia, this study used Contingent Valuation Method find possible willingness pay customers for service contributions. This found that (WTP) c...

A numerical procedure for the determination of equivalent grid block permeability tensors for heterogeneous porous media is presented. The method entails solution of the fine scale pressure equation subject o periodic boundary conditions to yield, upon appropriate averaging of the fine scale velocity field, the coarse scale or equivalent grid block permeability. When the region over which this ...

With the acceleration of urbanization and industrialization, regional development is becoming increasingly disordered. Thus, how to balance economic development and ecological protection is a key question. To comprehensively evaluate land development suitability, an evaluation index system for construction land and farmland suitability was established in this study based on natural and social-e...
