“…They found that formalities -procedures indicator accounts for 5.4% of potential trade cost savings, indicator advance rulings for 3.7%, indicator formalities -automation for 2.7%, and indicator fees and charges for 1.7%. Moïsé and Sorescu (2013) suggested that greatest impact on trade volumes and trade costs have the indicators related to the availability of trade-related information, the simplification and harmonization of documents, the streamlining of procedures and the use of automated processes. They found that the combined effect of improvements in these areas is greater than the simple sum of the impact of individual measures, reaching almost 14.5% reduction of total trade costs for low income countries, 15.5% for lower middle income countries and 13.2% for upper middle-income countries.…”
