Cato PA #557 & Average Tariff Statistics

A note worth passing along: Jim catches an odd statistical choice by Marian Tupy in his latest Policy Analysis, “Trade Liberalization and Poverty Reduction in Sub-Saharan Africa.” Check it out.

Using three countries to represent the average tariff of the 48 nations in sub-Saharan Africa is an embarrasingly bad approach, but apparently Tupy also avoided using an earlier base year that offered more data!

Another irony: Figure 7 makes it appear that Sub-Saharan Africa’s trade regime was the most liberal in the world in 1983!
