There are quantitative studies showing that TDD has little to no impact development time or code quality[0]. What has been found, however, is that writing code in short increments helps a lot (something that can be caused by using TDD). For more information on studies covering the topic (and much more), I highly recommend watching Greg Wilson's Software Engineering's Greatest Hits[1].
