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
Porter-Golden Foot & Mouth Collection, number 50
No full textEradication method, circa 1925, for dealing with foot-and-mouth disease in a group of cattle. Some are down on ground and other still stand. Writing on the photo or group of photos: 'This Collection of kodak pictures, gathered by the late, Dr. Frank D. Porter in the course of his life work and interest with diseased animals is bequeathed to the library of Texas A&M College at his request, in the hope it will be of service and help to students in the pursuit of their career. The pictures were made by Dr. F. D. Porter while on the Foot & Mouth disease in California in year of 1930 and in Houston in 1924. And some were acquired from G. E. Golden. Dr. Frank D. Porter, Born-Indiana-1879, Died-Ft. Worth, TX-May 22, 1950.' Physical description: Black and white print (photograph) 9x14.5mm."The humane feature of the argument can be disposed of by saying that all susceptible live stock are food-producing animals, and their ultimate distination is the slaughterhouse. ...The animals slaughtered in abattoirs for food are all in an apparently healthy condition, while the animals shot in corrals, and trenches, preparatory to deposal on account of this disease, are in many instances pitiable sights to witness. ...mucous membrane, lining the mouth, tongue, and gums, has sloughed off in large patches, leaving these surfaces in a raw state, which is evidenced by the depressed and painful expressions on the faces of animals affected. ...the feet are so painfully involved as to cause the affected animals to lie down continuously in order to avoid pain. ...the pictures presented in connection with this article, should convince anyone of the severity of the disease." - G. E. Golden. JAVMA. 1926.
Both Dr. Frank D. Porter and Dr. George E. Golden worked for the Unitied States Department of Agriculture, Bureau of Animal Industry. Dr. Porter was born and raised in Indiana in 1879, and graduated from Indiana Veterinary College in 1916. He enlisted in military service in 1918 and held the title of Government Meat Inspection for the BAI. Following the military service he continued his duties as animal health inspector out of the Fort Worth, Texas offfice. Dr. Porter married his wife Bertha in 1899 and later had one son who they named Eugene H.
Dr. George Edwin Golden born about 1878 in Illinois, was a 1907 graduate of McKillip Veterinary College, Chicago Illinois. He is listed in an 1919 issue of JAVMA as servicing in the military service and receiving a honarable discharge and returning to his duties for the BAI. He was married to a Mary Clarissa Vanderburgh in New Orleans, Laousiana in 1918. The 1920 Iowa, Sioux City U. S. Census has him as married, age 42, occupation Veterinary and employer as Government; and on a 1925 U. S. Census he is listed as having three daughters, ages 4, 3 and 1 years old. The 1940 Census taken near Los Angeles County California shows George Golden as widower, age 55 living with three teenage daughters with occupation of Inspector of Meat Packing. His date of death is unknown by this researcher
Three-Dimensional Models of Experimentally-Produced Lithic Artifacts Created using Expedient and Refined Photogrammetry Protocols
No full textThe data are divided into four ZIP files based on whether they contain core or flake models, and whether the models were created using an expedient or refined photogrammetric setup and protocol. Each of these .ZIP files contains the relevant 3D models in OBJ format. There are three files associated with each model (OBJ, MTL, and JPG texture). The files are named based on object ID, and the setup used to create them (i.e. expedient or refined). All models were processed and scaled in Agisoft PhotoScan Professional Edition. Geomagic Design X was used to center and align models around the origin.The data set consists of three-dimensional (3D) models of experimentally produced lithic artifacts created using both expedient and refined photogrammetric setups and processing protocols. Source images for all models were captured using a 12.1 megapixel Canon PowerShot SX260 HS compact digital camera. In our expedient protocol, objects were placed on a wire stand. The photographer moved around the object, and captured photos using Auto mode. In our refined protocol, objects were placed on a rotating turntable under controlled lighting conditions. The camera was placed on a tripod. Shutter speed, f-stop, and ISO were set manually. This refined protocol is described in Porter, S. T., Roussel, M., & Soressi, M. (2016). A Simple Photogrammetry Rig for the Reliable Creation of 3D Artifact Models in the Field Lithic Examples from the Early Upper Paleolithic Sequence of Les Cottés (France). Advances in Archaeological Practice, 4(1), 71-86. The associated paper discusses the relative fidelity of the models produced using these different workflows.

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
