Many theories have been posited for the growth in co-authorship in economic research output. This column uses new findings to assess the viability of the different explanations. Lower costs of global communication and increased pressure to produce greater research output play a role, but more information on hiring, promotional, and funding practices is required to assess the relative importance of the various factors behind the trend.

Informal collaboration is an integral part of academia. Studies of academic collaboration have mostly focused on formal collaboration, as measured by co-authorships. This column instead constructs a network of informal collaboration in financial economics, exploiting acknowledgements of assistance appearing in published papers. Three rankings of financial economists are constructed based on acknowledgement occurrence and centrality. Being helpful is not found to predict centrality in the informal collaboration network.
