Dear Colleagues,
We invite you to take advantage of lower fees by registering early for the Fourth World Congress of Environmental and Resource Economists. The deadline for early registration is April 30, 2010. This is also the date by which presenting authors must have registered in order for their paper to be included in the program.
There is a substantial increase in the fees after that date.
To register go to the WCERE 2010 web site, at www.wcere2010.org. You will also find on the web site a provisional program overview as well as useful information about the keynote speakers, accommodation, the venue, social activities, related events, etc.
We look forward to welcoming you to Montréal.
The Local Organizing Committee
WCERE 2010
Funny story (background post here): I had already early registered. Had to suffer the indignity of de-registering.
