摘要：The current paper uses a series of metrics of customs and administrative procedures produced by the World Bank to estimate gravity models. The metrics include estimates of the number of days at the border, the number signatures and the number of documents necessary for a product to cross the border of the importer and the exporter. Simulations using the estimated elasticities show that to improve trade reductions would need to be made in the different metrics. For the greatest benefits all trading partners would have to make the improvements. Additionally, some products are more sensitive to the metrics than others.
