Following the failure of Lehman Brothers in September 2008, short-term credit markets were severely disrupted. In response, the Federal Reserve implemented new and unconventional facilities to help restore liquidity. Many existing analyses of these interventions are confounded by identification...

This note’s aim is to investigate the sensitivity of Christakis and Fowler’s claim (NEJM July 26, 2007) that obesity has spread through social networks. It is well known in the economics literature that failure to include contextual effects can lead to spurious inference on “social network...
