We invite you to take part in a new initiative: the open assessment of a paper submitted to the journal Economics: The Open-Access, Open-Assessment E-Journal (www.economics-ejournal.org).
Alonso Aguilar Ibarra, Armando Sanchez Vargas, and Benjamin Martinez Lopez have submitted the paper "Economic Impacts of Climate Change on Two Mexican Coastal Fisheries: Implications to Food Security". ...
Now we are seeking experts to assess it. On account of your reputation and interests, you have been identified as a researcher who may be well suited for this purpose. Since the paper is receiving prominent treatment on our website, your assessment would be given prominence as well.
The paper to be assessed can be found in the discussion platform of Economics:
Please notice: For the assessment by invited readers we have no particular guidelines. You are free to provide just a few short comments or a more detailed report.
Your assessment should reach us until January 31, 2013.
My review can be found at the bottom of the link. It was a bit of a different experience writing an open review. I had to avoid my usual abusive ad hominem.
