The convergence of performance especially
in the “middle ground”—broadly the range
from rank 40 to 120—makes this space more
and more crowded (see figure 1.8). This trend is
bound to continue as most countries’ business
environment and policies are set to improve.
Thus, countries in the middle range may witness
a large change in their rank, even if the
underlying score changes only little. Should
the score remain the same, the rank is likely
to deteriorate: a score in the 2010 LPI yielding
a rank between 60 and 90 was equal to ranking
between 70 and 100 in the 2014 LPI (with
scores ranging roughly from 2.56 to 2.80; see
table 1.9).
