On the Dual Nature of Weak Property Rights

In the natural resource literature, convertional wisdom holds that weak property rights will cause a resource to be over-exploited. This is because weak property rights are typically perceived as a problem of input exclusion. In this paper, we first present evidence to the effect that weak property rights often take the form of contestable output- or output theft - and that this has an impact or resource use. We then propose a theoretical model of natural resource use under generally weak prperty rights - or weak state presence - when resource users face the dual problem of input exclusion output appropriation. We show that introducing the possibility that outputs can be contested acts as an output tax, with the added twist that resource users effectively determine the level of the tax. This tax has a depressive effect on input use. As a result, whether the resource is under-or over-exploited in equilibrium will depend on the relative severity of output appropriation and input exclusion problems when property rights are generally weak.Natural Resources, Property Rights, Trespass, Theft, Over-Exploitation,Under-Exploitation

High Noon On the Western Range: A Property Rights Analysis of the Johnson County War

Wyoming\u27s Johnson County War of 1892 is the historical basis of later popular depictions of the West as violent, and it influenced the development of Wyoming. Many see this era as the end of the open range system and the ascendancy of stock ranching and farming. Popular depiction argues that the event was an act of vigilantism of large foreign-owned firms against small individual settlers. We argue that the war was a conflict of property rights systems and use a model developed by Alston, Libecap, and Mueller to explain why violence broke out in Johnson County in 1892

As in Real Estate, Location Matters: Cellular Expression of Complement Varies Between Macular and Peripheral Regions of the Retina and Supporting Tissues.

The cellular events that dictate the initiation of the complement pathway in ocular degeneration, such as age-related macular degeneration (AMD), is poorly understood. Using gene expression analysis (single cell and bulk), mass spectrometry, and immunohistochemistry, we dissected the role of multiple retinal and choroidal cell types in determining the complement homeostasis. Our scRNA-seq data show that the cellular response to early AMD is more robust in the choroid, particularly in fibroblasts, pericytes and endothelial cells. In late AMD, complement changes were more prominent in the retina especially with the expression of the classical pathway initiators. Notably, we found a spatial preference for these differences. Overall, this study provides insights into the heterogeneity of cellular responses for complement expression and the cooperation of neighboring cells to complete the pathway in healthy and AMD eyes. Further, our findings provide new cellular targets for therapies directed at complement

Found it and we made it Made a safe range out of this. Some us died doin it. We made it. Then people move in who never held a rawhide through the old days. Fenced off my range. Fenced me off from water. Some of them like you paw ditches, and take out irrigation water, and so the creek runs dry sometimes, and I got to move my stock because of it. And you say we have no rights to the range.Stark (the Homesteader): You talk about rights. You think you got the right to say that nobody else has got any. Well, that ain t the way the government looks at it.Shane Paramount Pictures, 1953
