jacky, thanks for these posts. You’re good at explaining this stuff in simple, clear terms, that is, good at understanding it … . Had some bright moments reading.
As for the “Intra-European Net claims”, I guess you refer to the Target2 system? I’m following the per-nation totals of these in long term charts over at querschuesse.de (see auto-translated English version). Provides the best coverage of this that I’m aware of. So I get a bit more freightened every month as the numbers come in and have a rough idea how this system works, but I’m lost when it gets to details and effects. Looked at your arxiv paper and got nicely reminded of my own time with pdfLaTeX but lack the time and resources to dive into all this. A part of me wants to, and I’m always happy to understand a bit more when explained like you do, but then, it’s not my area of expertise …
(That’s also what makes me such a fan of these “simple” alternative currencies … it’s hacker ethics to only use a system you understand. You seem to share similar values, as you build models of what’s happening in the current system …)
Back to Target2. Do you think the current Target2 situation can have any major (crash style) consequences, or will it “just” cause bank liquidity problems like now? From what I understood from Stephan’s (above linked) site, negative Target2 balances are essentially accumulated national current account deficits (coming from trade deficits inside a too inhomogenous Euro zone, unable to be prevented by devalueing national currency as before). If so, then there are several hundred billions of debts out there that cannot be repaid from southern to northern national central banks via the ECB. And I wonder if that has potential for a new financial-economic crash? Over here, this is still a fringe topic and most economists seem not to care and / or not to understand …
