Charles I. Jones的一篇关于经济增长的论文

May 18, 2007– Version 1.51
Per capita income in the richest countries of the world exceeds that in the
poorest countries by more than a factor of 50. What explains these enormous
differences? This paper returns to two old ideas in development economics and
proposes that complementarity and linkages are at the heart of the explanation.
First, just as a chain is only as strong as its weakest link, problems at any point in
a production chain can reduce output substantially if inputs enter production in
a complementary fashion. Second, linkages between rms through intermediate
goods deliver a multiplier similar to the one associated with capital accumulation
in a neoclassical growth model. Because the intermediate goods' share of revenue
is about 1/2, this multiplier is substantial. The paper builds a model with complementary
inputs and links across sectors and shows that it can easily generate
50-fold aggregate income differences.
