  Abstract: In the last four years, daily deals have emerged from nowhere to become a multi-billion dollar industry world-wide. Daily deal sites such as Groupon and Livingsocial off er products and services at deep discounts to consumers via email and social networks. As the industry matures, there are many questions regarding the impact of daily deals on the market-place Important questions in this regard concern the reasons why businesses decide to o er daily deals and their longer-term impact on businesses. In the present paper, we investigate whether the unobserved factors that make marketers run daily deals are correlated with the unobserved factors that influence the business, In particular, we employ the framework of seemingly unrelated regression to model the correlation between the errors in predicting whether a business uses a daily deal and the errors in predicting the business' survival. Our analysis consists of the survival of 985 small businesses that off ered daily deals between January and July 2011 in the city of Chicago. Our results indicate that there is a statistically signifi cant correlation between the unobserved factors that influence the business' decision to o ffer a daily deal and the unobserved factors that impact its survival. Furthermore, our results indicate that the correlation coefficient is signifi cant in certain business categories (e.g. restaurants).
