C. S. Porter Interview, September 20, 1984
No full textC. S. Porter briefly mentions his background in physical education and his role as principal of the Central and Prescott schools in Missoula, Montana. He recalls how the Great Depression seemed to have little effect on the school children and how there didn’t appear to be a significant shortage of food or clothing for the students. He describes the city-wide decision to pay teachers less money during the 1930s to avoid laying them off. Porter notes that during his time a superintendent he dealt a number of issues including crowded classrooms and the lack of funds to expand.https://scholarworks.umt.edu/depressioninmissoula_oralhistory/1001/thumbnail.jp
Trachysphyrus uspallatae Porter
No full textTrachysphyrus uspallatae Porter Material Examined. 2 females, Argentina, La Rioja Province, Sierra de Velasco, San Pedro, 1600 m, 30- IV-2000, P. Fidalgo (FSCA, IMLA) This species was previously known only from Uspallata in Mendoza Province some 500 km distant in the southern Subandean Desert (Porter 1967). The specimens now recorded from La Rioja Province differ from the type series only in lacking white bands on gastric tergites 4-7.Published as part of Porter, Charles C., 2008, New Trachysphyrus Haliday (Hymenoptera, Ichneumonidae) in the albomarginatus species group from northwestern Argentina, pp. 1-9 in Insecta Mundi 2008 (55) on page 9, DOI: 10.5281/zenodo.517013

The Environmental Porter Hypothesis: Theory, Evidence and a Model of Timing of Adoption
No full textThe Porter Hypothesis postulates that the costs of compliance with environmental standards may be offset by adoption of innovations they trigger. We model this hypothesis using a game of timing of technology adoption. We show that times of adoption are earlier the higher the non-adoption tax. The environmental tax turns the preemption game with low profits into a game with credible precommitment yielding high profits (pro-Porter). If there is a precommitment game without environmental taxes, the introduction of a tax leads to lower profits (anti-Porter). An evaluation of the empirical literature indicates that the Porter hypothesis holds even for profit-maximizing firms under multiple market imperfections such as imperfect competititon, X-inefficiency, and agency costs. These are more likely to be present in sectors with large firms. In many case studies that we evaluate, though, we detect an element of explicit or implicit subsidies for environmentally friendly behaviour, which is in line with Pigovian policies.Environmental Policy, Strategic Trade Theory, Technology Adoption, Porter Hypothesis

Environmental policy without costs? A review of the Porter hypothesis
No full textThis paper reviews the theoretical and empirical literature connected to the so called Porter Hypothesis. That is, to review the literature connected to the discussion about the relation between environmental policy and competitiveness. According to the conventional wisdom environmental policy, aiming for improving the environment through for example emission reductions, do imply costs since scarce resources must be diverted from somewhere else. However, this conventional wisdom has been challenged and questioned recently through what has been denoted the “Porter hypothesis”. Those in the forefront of the Porter hypothesis challenge the conventional wisdom basically on the ground that resources are used inefficiently in the absence of the right kind of environmental regulations, and that the conventional neo-classical view is too static to take inefficiencies into account. The conclusions that can be made from this review is (1) that the theoretical literature can identify the circumstances and mechanisms that must exist for a Porter effect to occur, (2) that these circumstances are rather non-general, hence rejecting the Porter hypothesis in general, (3) that the empirical literature give no general support for the Porter hypothesis. Furthermore, a closer look at the “Swedish case” reveals no support for the Porter hypothesis in spite of the fact that Swedish environmental policy the last 15-20 years seems to be in line the prerequisites stated by the Porter hypothesis concerning environmental policy.Environmental policy; the Porter hypothesis; productivity; profitability
