Title: How Should Journal Quality be Ranked? An Application to Agricultural, Energy, Environmental and Resource 
	Economics
Abstract: The Thomson Reuters ISI Web of Science citations database (hereafter ISI) category of Economics has one 
	of the largest numbers of journals, at 304, of any ISI discipline, and hence has wide coverage. The paper 
	analyses the leading international journals in the Economics sub-disciplines of Energy, Environmental and 
	Resource Economics using quantifiable Research Assessment Measures (RAMs), and highlights the similarities 
	and differences in alternative RAMs. The RAMs are based on alternative transformations of citations taken 
	from the ISI database. Alternative RAMs may be calculated annually or updated daily to answer the perennial
	questions as to When, Where and How (frequently) published papers are cited (see Chang et al. (2011a, b, c)). 
	The RAMs include the most widely used RAM, namely the classic 2-year impact factor including journal self 
	citations (2YIF), 2-year impact factor excluding journal self citations (2YIF*), 5-year impact factor 
	including journal self citations (5YIF), Immediacy (or zero-year impact factor (0YIF)), Eigenfactor, 
	Article Influence, C3PO (Citation Performance Per Paper Online), h-index, PI-BETA (Papers Ignored - 
	By Even The Authors), 2-year Self-citation Threshold Approval Ratings (2Y-STAR), Historical Self-citation 
	Threshold Approval Ratings (H-STAR), Impact Factor Inflation (IFI), and Cited Article Influence (CAI). As 
	data are not available for 5YIF, Article Influence and CAI for one of the 20 journals considered, 13 RAMs 
	are analysed for 19 highly-cited journals in Energy, Environmental and Resource Economics in the ISI 
	category of Economics. Harmonic mean rankings of the 13 RAMs for the 19 highly-cited journals are also 
	presented. It is shown that emphasizing the 2-year impact factor of a journal, which partly answers the 
	question as to When published papers are cited, to the exclusion of other informative RAMs, which answer 
	Where and How (frequently) published papers are cited, can lead to a distorted evaluation of journal 
	impact and influence relative to the Harmonic Mean rankings.
Classification-JEL: Q10, Q20, Q30, Q40, Q50.
Keywords: Research assessment measures, Impact factor, IFI, C3PO, PI-BETA, STAR, Eigenfactor, Article Influence,
