This paper investigates ESG from the perspective of changes in input elasticities substitution and complementarity. Rather than compute these cost function, we them Input Distance Function (IDF). Our data are Refinitiv Eikon Datastream database. We focus on US economy due to her global role world hence spillover effects uncertainties rest world. The consist 5,798 companies comprising 38 industr...

in the presented research, heat transfer of a mobile electrolyte alkaline fuel cell (afc) (which the electrolyte has cooling role of system) has been considered. proper control volumes of system with specific qualification have been chosen. consequently, heat and mass transfer in control volumes have been assessed. considerations on them and contributed models lead to approve a double tube heat...

a hybrid hydro/wind/photovoltaic base on hydrogen storage system is designed to supply power demand of pump stations. the aim of this design is minimization of net present cost of the hybrid system. optimization problem is subject to reliable supply of the demand. the system is investigated in the north west of iran (meshkinshahr) and the local data is applied. about 12 pump stations are found ...

Furthermore, it is within the scope of this document to identify and present in detail the major institutional and organizational issues associated with Airport Capacity and Efficiency and specify the existing perc...

Based on stochastic frontier analysis and translog input distance function, this paper examines the total factor energy efficiency of China’s industry using input-output data of 30 subindustries from 2002 to 2014, and decomposes the changes in estimated total factor energy efficiency into the effects of technical change, technical efficiency change, scale efficiency change and inputmix effect. ...

Using a newly constructed data set on outward FDI from Germany, comprising both parent and affiliate panels for the period 1989-2001, this paper studies the location choice of German parents and consequences for labor demand across locations. Results indicate that large, relative skill abundant countires attract German FDI. Firms in skill-intensive industries seek skilled labor in their foreign...
