  Citation × Citation Citation Abstract Copy Title: Measuring the Effects of Catch Shares: Identifying Indicators and Establishing Baselines along the West and Northeast Coasts Author: Downs, Michael A., Shug, Don, Hartley, Marcus, Weidlich, Stev The Measuring the Effects of Catch Shares Project is a webportal-based effort that continues to compile and analyze data on ecological, economic, social, and administrative changes in groundfish catch share fisheries on the West Coast and in the Northeast. The purpose of the five-year project is to make the best available data and accompanying analyses readily accessible to the general public as well as to those with specific interests the fisheries, including fishery managers, fishermen, policymakers, legislators, and service business owners. Among other data, the project presents information on six key economic and social indicators across both fisheries. This presentation describes the overall project, its goals, and initial findings. Specifically described are methodological considerations used in determining how and why a much larger number of potential indicators considered during project planning and initial baseline data gathering processes were winnowed down to the final key economic and social indicators. These considerations included the public availability of data, data accuracy, confidentiality, geographic coverage, and replicability, among others. Specifically underlined by the project findings is the importance of extended baseline time series data in placing potentially catch share-related changes in the context of longer-term fishery fluctuations and trends of change. Another preliminary conclusion is related to the challenges of confidentiality that severely restrict the analysis of changes at the sub-regional and/or port level, which is requiring implementation of additional methodologies in later stages of the project to address data gaps.

  Citation × Citation Citation Abstract Copy Title: The Effect of Oyster Farm on the Neighboring Housing Value in Rhode Island Author: Uchida, Hiro, Sudhakaran, Pratheesh O., Opaluch, Jim, Puggioni, Gavino From 2000 onwards, the United States saw an increasing trend for the shellfish aquaculture practices especially along the Northeast coast. Despite the supporting majority of public regarding the shellfish aquaculture operations, these operations are sometimes opposed by local communities claiming the devaluation of housing property due to the construction of oyster farm. Since the uproars against the devaluing of housing property is directly affecting the lives of public, it is critically important to study the effect of construction of oyster farm on its value. A difference-in-difference (DoD) model within hedonic price model (HPM) was used to evaluate the effect of oyster farm on property value. We collected the details of the oyster farms operated in Rhode Island from the Coastal Resource Management Council (CRMC). Our housing sales data lists all the housing transactions in Rhode Island between 2000 and 2013. We used a linear mixed model with lot size as unit level fixed effect and city as random effect. The result showed that the DoD coefficient associated with interaction of distance bands and the construction of oyster farm, was statistically insignificant. The statistical insignificance of the coefficients suggests that there is not much change in housing value due to the construction of oyster farm. The analysis shows that houses further away from coastline will reduce the value of the property. One of the caveats of this study is lesser housing transactions since the construction of oyster farm happened in recent years.
