Lant Pritchett (1997): Divergence, Bigtime

1. What is Pritchetts argument that the world must have been more equal back in 1800 than it is today?
2. What suggestions does Pritchett make for how we should understand the limits of "convergence" and the "convergence club" to the (extended) North Atlantic?
3. The story today is different than the story Pritchett told two decades ago because of super-rapid growth in China ca. 1977-present, and rapid growth in India ca. 1990-present. If Pritchett were rewriting his article today, what changes would he have to make?
4. What countries have joined the convergence club that is the (extended) North Atlantic? What countries have fallen out of it? Does Pritchett give any reasons for why?
5. Does Pritchett give a reason--or even a guess--for the stability of North Atlantic growth rates since 1870?
