Model selection methods and nonparametric estimation of Levy densities are presented. The estimation relies on the properties of Levy processes for small time spans, on the nature of the jumps of the process, and on methods of estimation for spatial Poisson processes. Given a linear space S of...

Planning road maintenance and development activities, prioritizing road construction, reconstruction and rehabilitation works, performing project economic evaluations, forecasting road operation expenditures and road user effect always requires prediction of pavement behaviour. For this purpose...

We employ an open economy general equilibrium model to investigate the effects of government energy policy, with emphasis on corn-based ethanol, on the U.S. economy. The model specification incorporates world and domestic markets, assumes pollution costs from fuel consumption, and allows...
