One of the many exceptional aspects of the global financial crisis of 2008 was the prominence policy-makers and commentators gave to the importance of history in helping to determine responses to the crisis. Ben Bernanke, the Chairman of the US Federal Reserve System famously reached for his copy of Friedman and Schwartzs seminal volume on the 1930s depression to seek inspiration (Friedman and Schwartz, 1963). Comparisons with the great depression of the 1930s feature prominently in commentaries on the depth and spread of the global financial crisis and reveal the extent to which policy-makers seek to learn from the past (Calomiris and Haber 2014; Eichengreen 2015). But how relevant is the past as a guide to the present, or even the future, and how is it used when policymakers, bankers and the public are faced with difficult economic challenges? There is a growing literature on how the construction of heritage and nostalgia have been used to serve particular social and political interests (Waterton and Watson, 2015) but most economic historians seek lessons from history rather than examining how the past is constructed and used. Rather than following this path, UPIER will take an original approach by using archival evidence to focus on how and when participants in markets (bankers, policymakers, investors, regulators) actually construct an idea of the past and how they use that construction to guide their reactions to the challenges they face.

“Documenting Africans in Trans-Atlantic Slavery (DATAS)” (www.datasproject.org) develops an innovative method to explore African ethnonyms from the era of trans-Atlantic slavery, circa 1500-1867. Ethnonyms index African identities, places and historical events to reconstruct African culture that is linked to a history of slavery, colonialism and racism. The project centres on the need to understand the origins and trajectories of people of African descent who populated the trans-Atlantic world in the modern era. The development of a method for analysing demographic change and confronting social inequalities arising from racism constitutes a social innovation. The team’s methodology implements a research tool developed in Canada for handling ethnonyms that can be applied in a trans-Atlantic context from France and the United Kingdom to Brazil, the Caribbean and Africa. This innovation confronts methodological problems that researchers encounter in reconstructing the emergence of the African diaspora. A methodology for data justice is salient because ethnonym decision-making used in our digital platform, requires a reconceptualization of the classification systems concerning West Africans. This methodology depends on an open source relational database that addresses important decisions that researchers face in the field about how to develop best practices and a controlled vocabulary for four reasons. First, scholarly expertise on West Africans is scattered globally. Second, the slave trade was transnational, rarely limited to one country or population, and the transfer of Africans across borders reflects this global relationship between colonial and colonized. Third, DATAS makes available a vast amount of information of immense value to marginalized communities deprived of information on their own history. Fourth, the trans-Atlantic and trans-national nature of this project complements the aims of a platform predicated on global collaboration. The project treats ethnonyms as decision making tools as a method whose concepts require rethinking entrenched assumptions about demography, data justice and research transparency.
