We analyze the joint dynamics of religious beliefs, scientific progress and coalitional politics along both religious and economic lines. History offers many examples of the recurring tensions between science and organized religion, but as part of the paper’s motivating evidence we also...

We document the presence of multiple and varied constraints to small and medium firm growth. This presents both a practical problem for business training programs and a challenge to academic economists trying to identify mechanisms though which these programs may affect outcomes. External...
