Share of Paddy Production and Rice Processing Industries in Regional GDP (percentage)
& Regional Paddy Production (million ton)
Note: all regions except the Northwest and Central Highlands ‘export’ rice, although the Mekong Delta is by far the largest international exporter. More than 50% of the rice output is produced by the MKD and more than 90% of internationally exported rice comes from the MKD.

Closing Remarks • Alternative rice export policies have relatively small impact on
regional GDP, but large and differential regional impacts in this model. In general, policies other than increased trade (of some sort) greatly impact the Mekong River Delta region most in terms of lost profitability.
• Micro-simulation shows that the Vietnam Rice Export Ban in 2008 in the context of fragmented rice market negatively affects all regions and (almost) all household categories
• Free Trade Policy turns out preferred and the most pro-poor policy for Vietnam in terms of the net benefit (as the sum of consumer and producer surplus) and the net benefit ratio as the ratio of net benefit to household expenditure
