Regional cooperation arrangements (RCAs) have produced vastly dissimilar performances; some have spurred remarkable expansion in trade and cooperation among members, while several others have achieved little. Studies show that performances vary because RCAs differ from one another in important...

We review and interpret the main theoretical developments in the gravity literature from its very early, a-theoretical applications to the latest structural contributions. We also discuss challenges and implement methods to estimate empirical gravity equations. We finish with a presentation and...
