Prof Riccardo Scarpa

Professor in Economics


Riccardo Scarpa is an applied economist who was educated at the Univ. of Wisconsin-Madison (1993-98), with a first degree (Laurea) in Agricultural Science from the University of Tuscia, Italy (1983-88) and an MSc in Environmental Impact Assessment from University College of Wales, Aberystwyth (1989-90). In 1998 he moved to the UK to take up a lectureship first in Newcastle and then at York. In 2005 he took a chair at the Waikato Management School in NZ, where he still has academic involvement. In 2012-2014 he held the Gibson Chair in Environmental, Rural and Food Economics at Queens University Belfast. Since 2014 he has held a part-time associate professorship at the University of Verona at the dpt of Business Economics. Ric has acted as an expert for several national and international funding agencies (including the EU Commission) in grant proposal evaluations. He has also acted as external and internal member of several promotion committees, including a role as OECD member of the “Abilitazione Scientifica Nazionale” in Public Economics and Finance (sector 13/A3) for the Italian Government in 2013-14. 

Publishing and editorial engagements

Ric’s has co-authored over 150 peer-reviewed interdisciplinary papers which have been published in a variety of academic journals, including all top field journals in environmental and agricultural economics. Ric has acted as academic peer-reviewer for over 70 academic journals and as an associate editor and member of the editorial board of several field journals. He has supervised over 20 PhD students, most of whom went on to academic or research-based positions. His publications have been cited more than 3,000 times in ISI journals (h-index 32). He is currently serving as co-editor for the Australian Journal of Agricultural and Resource Economics. He also serves as member of the editorial board of other field journals. Ric’s google scholar hg-index is over 57. Soutar et al. (2015) report that a value of 56 is in the top 1% of the top 500 universities in USA, Canada, UK, New Zealand and Australia. 


Ric has a keen interest in making his research relevant to society and has been engaged in a variety of consultancy tasks using advanced stated choice survey design to derive estimates of nonmarket goods. His consultancy engagements touched on the economics of water, energy and transport utilities in the UK, Italy, Australia and New Zealand. More consultancy tasks were for international research organisations (e.g. FAO, CGIAR, OECD, etc.) and land management agencies (various national and regional parks) as well as local authorities.
