<b>Dear Apostolis,<br><br>One of the things I have been saying recently, is that ideally, 'material' economic coalitions, say the Brazilian solidarity economy counting 4 million workers, should work together using open design; THEN, choose to practice open book management; in this way, all supply and demand information, but also the transparency of ethical practices, would lead to much greater mutual coordination, possibly replacing market pricing as allocation mechanism (replacing one summary and misleading information point, with a multitude of factors to take into account).<br>
<br>No doubt, this practice would be aided, if they could use something like what you are proposing? Or am I interpreting this wrong?<br><br>Michel<br></b><br><div class="gmail_quote">On Fri, Jul 15, 2011 at 7:59 AM, Apostolis Xekoukoulotakis <span dir="ltr"><<a href="mailto:xekoukou@gmail.com">xekoukou@gmail.com</a>></span> wrote:<br>
