Convergence in the Ease of Doing Business
   Suppose that one were to divide the countries included in the latest Doing Business   report into two groups. Call the first group (made up of some 44  countries) the “worst quartile”—that is, the countries with the  costliest and most complex procedures and the weakest institutions. Call  the other group the “best three quartiles.” Then let’s ask ourselves:  how many days did it take to establish a business in both groups in  2005? The answer is 113 days in the worst quartile and 29 days in the  best three quartile countries, meaning that in 2005 there was a gap of  84 days between the two sets. Now, let’s repeat the exercise for 2013.  The worst quartile is down to 49 days and the best three quartiles is  down to 16; the gap between the two has narrowed to 33 days, which is  still sizable but a lot less than 84. Repeat the same exercise for time  to register property and time to export a container. For property  registration, the gap in 2005 was 192 days and by 2013 it has narrowe...
