The h-index is the largest number h such that h publications have at
least h citations. The index reflects
both the number of publications and the number of citations per publication. One
unperceived deficiency of this metric is that it is Pareto-inefficient. A
¡°citation surplus¡± would be absent and, thus, the h-index would be efficient for a researcher if all his h papers that are equal or above his h-index received exactly h citations. This inefficiency would not
be of great concern if those h papers
were normally distributed. However, the rank from top to bottom does not decay
exponentially. The decay follows the power law known in the literature as
Lotka¡¯s law. To remedy this deficiency, I suggest the h-index be supplemented by a researcher¡¯s citation surplus.
