    The Railroad’s Impact on Land Values in the Upper Great Plains at the Closing of the Frontier

    We show that the impact of transportation improvements on land values is complex with a direct, positive relationship on the price of land and also a positive relationship with the ratio of improved acres to total acres, another important influence on the per acre price of land. We construct a two step estimation that removes the impact of transportation outlets on the ratio of improved to total acres before including the transportation variables and the adjusted ratio variable as independent variables in a regression on price per acre. This estimation gives us the expected positive impact of railroads on land price. We also use Box-Cox regressions to show the semi-log form, a common model specification, may be inappropriate for our data and possibly then for other land price research.Box-Cox, Railroads, Great Plains

    Evaluating Pooled Evidence from the Reemployment Bonus Experiments

    Social experiments conducted in Pennsylvania and Washington tested the effect of offering Unemployment Insurance (UI) claimants a cash bonus for rapid reemployment. This paper combines data from the two experiments and uses a consistent framework to evaluate the experiments and determine with greater certainty the extent to which a reemployment bonus can affect economic outcomes. Bonus offers in each of the experiments generated statistically significant but relatively modest reductions in UI receipt. Since the estimated impacts on UI receipt were modest, the reemployment bonuses did not generate the UI savings necessary to pay for administering and paying the bonuses. Hence, contrary to earlier findings from a bonus experiment conducted in Illinois, findings from the Pennsylvania and Washington experiments strongly suggest that a reemployment bonus is not a cost-effective method of speeding the reemployment of UI claimants.unemployment, insurance, bonus, experiments, O'Leary, Decker

    Environmental Inspection Proclivity and State Manufacturing Growth: The US Experience from the 1990s

    Get PDF
    In this paper we construct a ranking of states based on their proclivity to inspect facilities for environmental compliance. Our measure utilizes state-level inspections data supplied by the US Environmental Protection Agency. After developing our ranking, we use it to predict state-level growth in manufacturing establishments. In doing so, we find support for the notion that enforcement intensity adversely impacts such growth. Our results offer insight into why existing studies that examine the impact of environmental regulation on location and growth produce inconsistent results.Monitoring and Enforcement, Environmental Regulations, Business Formation Growth

    Electric vehicle charging and routing management via multi-infrastructure data fusion

    The introduction of Electric Vehicles (EVs) has placed a strain on the aged and already overworked electrical grid. With each EV requiring the same amount of power as 3 to 140 single family homes, depending on how fast the charge occurs, measures need to be taken in order to protect the electrical grid from serious damage. The electric grid renovations proposed by the U.S. department of energy, commonly referred to as the smart grid, could help accommodate an even greater EV penetration. The introduction of the smart grid and other cutting-edge technologies create the potential for applications which provide new consumer conveniences and aid in the preservation of the electrical grid. This thesis aims to create one such application through the production of a prototype system which takes advantage of current and in-development technologies in order to route an electric vehicle to the closest and least detrimental charge station based on current conditions. Traffic conditions are assessed based on data collected from both ITSs (Intelligent Transportation Systems) and VANETs (Vehicle Ad-hoc Networks), while grid information is gathered through the early stages of the Smart Grid. The system is hosted in a cloud environment base on the current trend of offloading Information Technology systems to the cloud ; this also allows for the advantages of a shared data space between sub-systems. As part of the thesis the prototype system was put through a stress test in a simulated environment in order to both establish system requirements and determine scalability for use with larger maps. The system requirements were compared with the technical specifications of an off-the-shelf GPS routing device. It was determined that such a device could not handle routing with such extensive underlying data, and will require hosting the prototype in a cloud environment. The system was also used to perform a case study on charging station placement in the Greater Rochester area. It was determined that the current charging stations are insufficient for a significant number of electric vehicles and that adding even six stations would provide a greater EV operational area and provide a more uniform distribution of charging station usage

    How to Define a Word for Your Students: An Introduction to Lexicography for Classroom Teachers

    Get PDF
    Classroom teachers are often required to define words for their students, yet few have any training in how to do so. With proper training, however, classroom teachers are able to provide their students with definitions superior to those in any dictionary because they are uniquely able to determine what information the student needs and how to convey it in a way that the student can understand. Without principles and techniques for defining words, however, teachers will find it difficult to select appropriate content for their definitions and present it in ways that are comprehensible and useful to their students. The leading learner’s dictionaries contain principles and techniques that teachers can apply in the classroom. In this paper, the author explains these principles and techniques and presents a two-sentence template for defining words in the classroom. The author then shows how teachers can use this template along with the defining techniques to define a wide range of words and adapt the content of their definitions to a wide range of defining situations. Intended as a practical guide to teachers, the paper concludes with numerous examples which illustrate how to adapt the template and defining techniques to a wide range of classroom defining situations. The paper also includes two appendices teachers can consult when writing their own definitions: an outline of the defining process and a summary of definition styles for quick reference
