Rules of the Game (2004 round)

As every approach to setting up a Top list seems to be debatable (there is no such thing as a 'perfect list'!), one should realize that along this way some - probably equally relevant - scientific output is not being measured. Therefore the Top-40 list should be understood as being indicative for ISI output only.

Who is included in the Top-40 list?

1. Economists who publish in relevant ISI journals, and who graduated from a Dutch university ('Ph.D.') Their affiliation is of no interest (can be anywhere in the world).
2. Economists who publish in relevant ISI journals, and who graduated from a university outside The Netherlands. They must have an affiliation with one of the participating Dutch universities and/or institutions, for at least 50% in total. Reference date for the current Top lists is set at January 1, 2004.

Which articles are included?

Only the following ISI publication types (1998-2002¹) are included: 'articles', 'letters', 'notes' and 'reviews' (but not 'book reviews'). All other ISI publication types, such as '(meeting) abstracts', 'corrections' and 'editorials' are NOT included.

Which formulas are used?

Top-40 of Economists:

Pi = w _authors * w _impact

Where

• Pi is the score of publication i



• w _authorsis defined as

  2

  ---------------

  1 + number of authors




• and w _impact is defined as the weighted and normalized impact factor for the journal²

Adding up the scores of each publication gives the individual score of each author.

Top-10 of economics departments of Dutch universities/institutes:

	w impact * fte
Pi =	---------------
	a(pi)

where

• Pi is the score of publication i
• w _impact is defined as the weighted and normalized impact factor for the journal
• fte=part time factor of the author (i.e. percentage of his or her time the author is affiliated with this department/institute (0-100%))
• a(pi)=#authors of publication i

Adding up the scores of all authors affiliated to a specific university/institute gives the scores of all universities/institutes.

Which output is achieved?

• Top-40 of Economists, consisting of names of authors, affiliation, total score over 1998-2002.
• Top-10 of economics departments of Dutch universities/institutes, consisting of names of universities/institutes, total score of its affiliated authors (corrected for part time factors) over 1998-2002.
• "Tip parade" of Economists, consisting of names of authors, affiliation, total score of publications in 2002

1 Located in Web of Science for the database years 1998-2002. Publications falling outside the database years are not counted

2? The journal impact is based on 0.60 x mean scores calculated by the CWTS for 1996-2000 plus 0.20 x the 2001 impact factor and 0.20 x the 2002 impact factor. Normalization per field is based on the top 5 journals per field.
