Ken Dodd has had interesting things to say on the topic.

If you search Google for "laughter sociolinguistics" there are many, many results.

The Ph.D.-dissertation  by Monika Vöge on laughter in business meetings might be of interest: http://static.sdu.dk/mediafiles//Files/Information_til/Studerende_ved_SDU/Din_uddannelse/phd_hum/afhandlinger/2009/Voege2008_Laughter_in%20_BusinessMeetings.pdf

Hi Diksha,

There are some really excellent references listed above from conversation analysis.  I would also suggest the work of P. Glenn.  He did a fine dissertation at University of Texas Austin and a number of follow up articles.  I have also attached one of our pieces on the use of laughter in individuals with aphasia.  It gives a few references to Glenn's work and gives you a perspective from a different population.
