My work focuses on agricultural and trade policy analysis, innovation in agrifood systems and analysis of agrifood value chains, all areas of fundamental importance to the functioning of the agrifood sector. Much of my career has involved applying economic analysis to assess the efficiency, effectiveness and equity of the EU Common Agricultural Policy (CAP), but more recently I have been focusing on the economics of existing and novel land-uses in New Zealand and technology adoption more generally. I am interested in quantifying the impact of innovation on the performance of either the agrifood system as a whole or of particular sectors within the industry. Linked to this is my research on the operation of value chains in developed and developing countries and the links with food security, which also provides useful information for policy makers. Many of my projects involve collaboration with researchers from other areas including agriculture, ecology, computer science and social science.
