Just a quick follow-up to a post on housing data from a couple of weeks ago.  I had a good call with Harriet Newburger at the Federal Reserve Bank of Philadelphia (Department of Community Affairs) who was one of the organizers of the event.  In her estimation the topic of entrepreneurship as it relates to housing data had not come up at the conference in question.  Most of the focus of the event had been on getting better foreclosure data and they expect a summary publication in the coming months on the event.  We both agreed this is an area that has great research potential given data coming from court records and other services on foreclosure and the opportunity to tie that public data into different data sets on businesses, although neither of us is aware of work underway in the area.  Certainly in doing so, the distinction between how the housing crisis will affect self-employment would be a different topic than its relationship to employer businesses.
