Are there any non-paywalled reputable economics journals? I'm contributing to another open-source economics project, and was looking to compile a list of primary sources for modern developments in the field.

Basically something to help bridge the (occasionally decades long) time lag between what's taught at an undergrad/ introductory grad level and what's being researched in the field today.

Unfortunately as many in academia know, companies like Elsevier and others have most major publications locked up behind corporate paywalls, which makes them broadly incompatible with the principles of OSS/OSD.

There's Arxiv (and Vixra for the braver), but preprint servers are not really what I'm looking for. It's hard to separate the wheat from the chaff on many of them. 

I'd like something with some editorial content, and especially peer-review.

I'd appreciate any suggestions.
Theoretical Economics (TE) and Quantitative Economics are two open access, peer reviewed journals. The former I know is of very good quality, arguably the top "field journal" in microeconomic theory.
