BACI: International Trade Database at the Product-level The 1994-2007 Version

摘要: This paper documents the construction of BACI, our international trade database, which covers more than 200 countries and 5,000 products, between 1994 2007. New approaches have been developed to reconcile data reported by almost 150 United Nations Statistics Division, collated via COMTRADE. When both exporting importing report Comtrade, we two different figures for same flow, so it is useful these into a single figure. To do this, firstly, as import values are CIF (cost, insurance freight) while exports FOB (free on board), transport rates be estimated removed from values. We regress observed CIF/FOB ratios given flow gravity variables product-specific world median unit value. In second step evaluate reliability reporting. decompose absolute value mirror flows using (weighted) variance analysis. These measures used weights in reconciliation each bilateral twice. Taking advantage this information end up with large coverage reliable data, especially terms unit-values. BACI freely available online users COMTRADE product classifications.
