This paper investigates the effect of economic policy uncertainty (EPU) on gambling activity in China. Based on a theoretical model, we hypothesize that EPU increases the demand for hope which raises the willingness to pay for lottery tickets, resulting in higher lottery sales. We estimate a...

We quantify the prevalence of undisclosed influencer posts on Twitter across a large set of brands based on a unique data set of over 100 million posts. We develop a novel method to detect undisclosed influencer posts and find that 96% of influencer posts are not disclosed as such. Despite...
