When analyzing terms-of-trade shocks, it is implicitly assumed that the economy responds symmetrically to changes in export and import prices. Using a sample of developing countries our paper shows that this is not the case. We construct export and import price indices using commodity and manufacturing price data matched with trade shares and separately identify export price, import price, and global economic activity shocks using sign and narrative restrictions. Taken together, export and import price shocks account for around 40 percent of output fluctuations but export price shocks are, on average, twice as important as import price shocks for domestic business cycles.
This paper estimates a gravity model to address the issue of whether intra-Arab trade is too little. Although gravity models have been extensively used to measure bilateral trade among countries, they have—to the best of our knowledge—never been used to measure intra-Arab trade. Our results suggest that intra-Arab trade and Arab trade with the rest of the world are lower than what would be predicted by the gravity equation, suggesting considerable scope for regional—as well as multilateral—integration. The results also suggest that intra-GCC and intra-Maghreb trade are relatively low while the Mashreq countries exhibit a higher level of intragroup trade.
