Jason received his doctorate in Economic History from the University of Limerick in 2002. The subject of his thesis was the use of tariffs in Ireland in the interwar years. He then undertook a post-doctoral thesis at Trinity College Dublin, where the focus of his work was on creating GDP estimates for Ireland in the 19th century. Following his time at TCD, Jason joined Coventry University as part of the Centre for Local Economic Development (CLED). Jason has worked for the last decade in Coventry, focussing on statistical series and economic development. He is currently located in the Centre for Business in Society, where he works as a research Fellow. His most recent research has been published in the Cambridge Journal of Economics and relates to the creation of an Irish Wage Index for the 19th Century.

The development of long-run statistical series are an integral part of current attempts to improve our understanding and implementation of economic development. By improving statistical coverage and statistical analysis over an extended time period we make important lessons from our past relevant to contemporary efforts to advance policy for sectors such as the automotive industry. This research helps links past to present for a better future.
