1. 1. Quantum transport in photoswitching molecules : An investigation based on ab initio calculations and Non Equilibrium Green Function theory

   Författare :Anders Odell; Anna Delin; Anders Niklasson; Jonas Fransson; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; molecular electronics; electron transport; electron structure; density functional theory; non equilibrium green function theory; Electronic structure; Elektronstruktur;

   Sammanfattning : Molecular electronics is envisioned as a possible next step in device miniaturization. It is usually taken to mean the design and manufacturing of electronic devices and applications where organic molecules work as the fundamental functioning unit. LÄS MER

3. 2. On specification and inference in the econometrics of public procurement

   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; auctions; dependent variable transformation model; green public procurement; indirect inference; instrumental variable; latent variable; log-generalized gamma distribution; maximum likelihood; measurement error; non-linear least squares; objective effectiveness; orthogonal polynomial regression; prediction; simulation estimation; structural estimation; nationalekonomi; Economics; Econometrics; ekonometri;

   Sammanfattning : In Paper [I] we use data on Swedish public procurement auctions for internal regularcleaning service contracts to provide novel empirical evidence regarding green publicprocurement (GPP) and its effect on the potential suppliers’ decision to submit a bid andtheir probability of being qualified for supplier selection. We find only a weak effect onsupplier behavior which suggests that GPP does not live up to its political expectations. LÄS MER
