Economic impacts of TAC regulation: A supply-driven SAM approach

Estimating effects of exogenous output changes: an application of multi‐regional social accounting matrix (MRSAM) method to natural resource management

“…The structure of the MEE version of the MRSAM model is similar to the model in Fernandez‐Macho et al. () or to the model in Seung and Waters () except that the MEE version used here is a multi‐regional version. Table displays the impacts obtained from the MEE version of the MRSAM model on output of a hypothetical 10 per cent reduction in pollock TAC in Alaska for comparison against results from the adjusted demand‐driven MRSAM model shown in Table .…”

Measuring the economic linkage of Alaska fisheries: A supply-driven social accounting matrix (SDSAM) approach

“…It should be noted that previous studies (e.g., Leung and Pooley, 2002;Cai et al, 2005;Fernandez-Macho et al, 2008) have indicated that the Ghosh methodology suffers from a problematic theoretical interpretation of the model, especially in cases where it is used to explain changes in physical output arising from changes in physical factor inputs. Consequently results from a Ghosh model often should be interpreted with caution.…”

“…In the literature, regional economic impacts of fisheries have been studied using demand-driven input-output (IO) models (e.g., Steinback, 1999), supply-driven input-output (SDIO) models (e.g., Leung and Pooley, 2002), and social accounting matrix (SAM) models (e.g., Seung and Waters, 2006a). Recently, Fernandez-Macho et al (2008) used a supply-driven social accounting matrix (SDSAM) to estimate economic impacts of a more than 50% reduction in hake TAC on fishing sectors and the overall economy of Galicia, Spain. Seung and Waters (2006b) discuss and compare various regional economic models used to assess fisheries impacts.…”

“…Also for complex production sectors such as Alaska fisheries, it is not necessarily an easy task to derive the changes in final demand that would map to the initial change in output on the supply side. This study follows the approach used by Fernandez-Macho et al (2008) applied to the Alaska fisheries sectors.…”
