Nam, Sungjoon; Manchanda, Puneet; Chintagunta, Pradeep K. - In: Marketing Science 29 (2010) 4, pp. 690-700

This paper documents the existence and magnitude of contiguous word-of-mouth effects of signal quality of a video-on-demand (VOD) service on customer acquisition. We operationalize contiguous word-of-mouth effect based on geographic proximity and use behavioral data to quantify the effect. The...

Cabras, Stefano; Fidrmuc, Jan; de Dios Tena Horrillo, Juan - In: Economics: The Open-Access, Open-Assessment E-Journal 11 (2017) 2017-15, pp. 1-20

Parametric regression models are often not flexible enough to capture the true relationships as they tend to rely on arbitrary identification assumptions. Using the UK Labor Force Survey, the authors estimate the causal effect of national minimum wage (NMW) increases on the probability of job...
