Economic theory suggests that the primary impact of trade liberalization will be on the overall level of trade, with a roughly parallel increase in exports and imports as a percentage of GDP. This is likely to require a modest depreciation of the real exchange rate in order to ensure that exports increase as much as imports, and leave the balance of trade unchanged. The export increase is likely to be concentrated in a relatively narrow range of products, products which use intensively the country's abundant factor of production (unskilled labour in the case of Bangladesh), while the import growth is expected to be much more diversified and more capital intensive.
