IntroductionIntroduction China concluded bilateral negotiations with China concluded bilateral negotiations with
member countries of the World Trade member countries of the World Trade Organization (WTO) and gained entry in Organization (WTO) and gained entry in January 2002. January 2002.
This event was preceded by a major This event was preceded by a major breakthrough in trade negotiations between breakthrough in trade negotiations between China and the US in October 2000 when China and the US in October 2000 when President Clinton signed the US China President Clinton signed the US China Relations Act. Relations Act.
• Under the Act, China accepts pork from any packing Under the Act, China accepts pork from any packing plant approved by the Food Safety and Inspection plant approved by the Food Safety and Inspection Service, thus phasing out its restrictive import and Service, thus phasing out its restrictive import and distribution procedures. distribution procedures.
IntroductionIntroduction The USDA estimates accession of China to the The USDA estimates accession of China to the
WTO will add $1.6 billion to US exports of WTO will add $1.6 billion to US exports of grains, oilseeds and oilseed products, and grains, oilseeds and oilseed products, and cotton by 2005. cotton by 2005.
Many analysts expect demand for pork in Many analysts expect demand for pork in China to increase by about 7% based on a China to increase by about 7% based on a tariff reduction from 43% to 12% by 2004.tariff reduction from 43% to 12% by 2004.
This implies that, China’s pork consumption by This implies that, China’s pork consumption by would be three times larger than the 529,000 would be three times larger than the 529,000 metric tons exported in 1998. metric tons exported in 1998.
IntroductionIntroduction In 2004, US pork exports exceeded $2 In 2004, US pork exports exceeded $2
billion in total value and 995,000 metric billion in total value and 995,000 metric tons in volume. tons in volume.
This represents an increase of over 35% This represents an increase of over 35% by volume and 40% by value compared by volume and 40% by value compared to exports in 2003 (NPPC, 2005). to exports in 2003 (NPPC, 2005).
China’s 1.2 billion people consume over China’s 1.2 billion people consume over half the pork produce in the world. half the pork produce in the world.
IntroductionIntroduction Chinese consumers prefer pork variety Chinese consumers prefer pork variety
meats which includes by products such as meats which includes by products such as stomachs, kidneys, hearts and tongues, stomachs, kidneys, hearts and tongues, which traditionally have little value in the which traditionally have little value in the US. US.
According to USDA, cutout values for US According to USDA, cutout values for US hogs have fallen recently because of a drop hogs have fallen recently because of a drop in the price of these variety meats. in the price of these variety meats. However, increased exports to China will However, increased exports to China will bolster prices to pork producers without bolster prices to pork producers without raising domestic prices for the US raising domestic prices for the US consumer. consumer.
IntroductionIntroduction
In 2004, US live hog prices would have In 2004, US live hog prices would have been about 30% lower if US pork exports been about 30% lower if US pork exports were instead sold in the domestic were instead sold in the domestic market. market.
According to Hayes (2005, 2001), the According to Hayes (2005, 2001), the demand for pork by 1.2 billion Chinese demand for pork by 1.2 billion Chinese consumers could boost the value of hogs consumers could boost the value of hogs by $5 per head when the agreement is by $5 per head when the agreement is fully implementedfully implemented
IntroductionIntroduction With regards to the rest of the economy, there With regards to the rest of the economy, there
have been many estimates of the impact have been many estimates of the impact China’s accession into the WTO. China’s accession into the WTO.
Goldman Sachs states that by taking into Goldman Sachs states that by taking into account effects such as increases in foreign account effects such as increases in foreign direct investment, China’s WTO accession direct investment, China’s WTO accession could translate into an estimated $13 billion in could translate into an estimated $13 billion in additional US exports by 2005. additional US exports by 2005.
Many sectors of US businesses are expected Many sectors of US businesses are expected to prosper. This includes information to prosper. This includes information technology, services, and agriculture technology, services, and agriculture
Purpose of StudyPurpose of Study
This paper examines the potential impact This paper examines the potential impact of trade liberalization on the US pork of trade liberalization on the US pork industry in an applied comparative static industry in an applied comparative static general equilibrium model of production general equilibrium model of production and trade. and trade.
The model generates comparative static The model generates comparative static adjustments in outputs and factor prices adjustments in outputs and factor prices due to changing output prices. Input due to changing output prices. Input substitution is critical and the paper substitution is critical and the paper examines sensitivity of results to constant examines sensitivity of results to constant elasticity substitution. elasticity substitution.

Higher prices are expected for exporting industries in the Higher prices are expected for exporting industries in the move to free trade. Using export and import elasticities of move to free trade. Using export and import elasticities of 1 and -1, a price increased of 15% is predicted for pork, 1 and -1, a price increased of 15% is predicted for pork, pork varieties, and the rest of agriculture along with pork varieties, and the rest of agriculture along with services while a fall of 15% in price is predicted for the services while a fall of 15% in price is predicted for the manufacturing sector. manufacturing sector.
