INTRODUCTION Motivations: The European consumer preferences of high-quality beef imports from Mercosur: the influence of the EU s trade policy. Objective: - Upgrading (downgrading) effect and welfare effect of TRQ s components in trade. - To shed some light on the possible outcome of present trade negotiations between the EU and MERCOSUR, specially for beef trade.

TRADE BARRIERS AND QUAL- ITY TRADE: state of arts Quality effect of trade barriers - The quality upgrading effect of transport cost (Alchian and Allen 1983) - The quality upgrading effect of specific tariff (Borcherding 1978), (Hummels 2004) - The upgrading effect of a quantitative restriction (Falvey 1979), (Rodriguez 1979), (Aw and Roberts 1986), (Feenstra 1988), (Boorstein and Feenstra 1991) - No quality effect of an ad-valorem tariff (Boorstein and Feenstra 1991), (Falvey 1979) - Quota doesn t upgrades quality necessarily and an ad-valorem tariff doesn t keep unchanged the quality trade composition under imperfect competition (Krishna 1987) - The downgrading effect of an ad-valorem tariff (Hummels 2004) TRQ literature - Demand side analysis of the efficiency and redundancy of TRQ s components Boughner, of Gorter and Sheldon (Boughner and Sheldon 2000) - Trade creation effect of the TRQ compared to a simple quota and to prohibitory tariffs (Abbott and Paarlberg 1998)

THE MODEL Hypotheses: - partial equilibrium model. - a representative consumer. - 2 qualities of the same good: and m h. - CES utility function improved with quality parameters (Hummels 2004). U(, m hi, m ho ) = (λ h (m hi + m ho ) σ 1 σ + λ l ( ) σ 1 σ σ ) σ 1 where λ h λ l. - a TRQ applied to the high-quality good: m h = m hi + m ho (Van der Mensbrugghe and Mitchell 2003). - a (ad-valorem+specific)tariff affects low-quality good.

R p l + p h (m hi + m ho ) (µ) q h m hi (θ) m hi, m ho, 0 where, σ: elasticity of substitution. λ h and { λ l : quality parameters => λ h λ l phi = p p h = hw (1 + t h ) if m h = m hi q h p ho = p hw (1 + t) + T if m h = m ho > q h p l = p lw (1 + t) + T q h : quota of the high-quality. µ and θ are the Lagrange s multipliers. + λ l ( ) σ 1 σ σ ) σ 1 We construct the Lagrangian and we obtain the Kuhn-Tucker conditions.

Then we construct the relative import demands m h, in and out-of the quota, because we are interesting on import quality composition. p l µ = ( ) σ ( λ h ) σ θ + µp hi λ l m hi if m h = m hi q h (1) m ho = ( p lλ h ) σ p l µ ( ) σ ( λ h ) σ p ho λ l θ + µp hi λ l if m h = m ho > q h (2) 3.1. Comparative statics Theoretical results: m h / T > 0 Quality Upgrading effect of a specific tariff out-of-quota m h / t < 0 Quality Downgrading effect of an ad-valorem tariff out-of-quota m h / t h = 0 NO Quality effect due to an ad-valorem tariff in-quota m h / q h = 0 NO quality effect due to a high-quality quota

The EU trade policy vis-à-vis the MERCOSUR The GSP for Mercosur doesn t include the sensible products (beef, chicken and poultry meat, pork meat, wheat, corn, dairy products and eggs products. According to WTO conditions, the EU concedes to Mercosur the TRQ to improve the access market for some products. - Sheep and Goats meat: t (Argentina) and 5800 t (Uruguay) -current access. - Beef (fresh, chilled and frozen): t (Argentina) and 2300 t (Uruguay) -minimum access. - Beef (frozen): t (TRQ non allocated to Mercosur but Brazil profits the most). - Chicken and Poultry meat: t (Brazil) -minimum access. - Corn: t (TRQ non allocated to Mercosur)was opened when Spain and Portugal enter in the EU (1986). - Sugar: t (Brazil) when Finland enter to the EU (1995). - Beef (frozen): t of frozen beef and t of frozen beef intended for processing (TRQ non allocated to Mercosur) when the European East countries enter in the EU (2004). - Hilton Beef: t (Argentina), 6300 t (Uruguay), 5000 t (Brazil) and 1000 t (Paraguay)

14 5. CONCLUSION 14 Début Préc. Suiv. Fin Retour Plein Ecran Fermer Quitter The theoretical and empirical results agree with about the next relationship between TRQ components and quality in trade. - Quality Upgrading effect when a specific tariff increases. - Quality Downgrading effect when an ad-valorem tariff increases. - No quality effect when the in-quota tariff increases or when the high-quality quota increases. For welfare results: - The consumer surplus increases under the out-of-quota tariff elimination. - All scenarios show a reduction on tariff revenue, even under the augmentation of the high-quality quota. - The quota rent for high-quality exporters increases when the in-quota tariff decreases and when the high-quality quota increases. - The export revenue for both quality exporters increases only when the out-of-quota tariff decreases. Which is the optimal trade agreement between the EU and Mercosur in the beef sector?. - generation of a iso- exporter utility (export revenue+rents) surface, with all the possible combination of TRQ s components. - generation of a iso- importer utility (consumer surplus+tariff revenue) surface, with all possible combination of TRQ s components. Which would be the allocation between high and low-quality goods if a total quota is applied?.
