Is China a Northern Partner to Mercosul?

We contrast Free Trade Areas involving Mercosul and the EU25, the US and China, respectively, using a new CGE model and associated database. Roughly, the China FTA lies halfway the other two, a bias towards the US pattern being suggested. When considering China a new Northern partner, protective deals don’t seem advisable. China’s advantages should prevail when facing the US or the EU: its need of capital goods, for instance, may open profitable cross-exchanges. China’s emergence can be a positive factor, if placed in an enlarged policy space where, together with its Asian neighbours, it counter-balances the US-EU polarity.

Modelo de equilibrio geral para simulação de políticas de distribuição de renda e crescimento no Brasil

Apresenta os resultados de um projeto de pesquisa que tem como objetivo a construção de um Modelo Aplicado de Equilíbrio Geral para a Economia Brasileira ("Computable General Equilibrium (CGE) Model"), voltado para a simulação de políticas públicas de crescimento e distribuição de renda. Após a caracterização e apresentação do modelo adotado ("Brasil CGE 95"), são realizadas treze simulações, onde comparam-se os resultados do ano base (95) com os obtidos em cada experimento, incluindo: indicadores macroeconômicos (PIB, Consumo, Déficit Público, Balança ComerciaL.), a remuneração anual dos dez fatores de produção do modelo (oito tipos de trabalho, dois tipos de capital ), a renda anual dos nove grupos de famílias do modelo, indicadores de pobreza/distribuição e indicadores variados como o emprego/produção setorial, taxa de câmbio real e o índice relativo de preços

Essays on the general equilibrium effects of barriers to trade on economic growth, foreign trade and the location of economic activity in Brazil

This work presents a fully operational interstate CGE model implemented for the Brazilian economy that tries to quantify both the role of barriers to trade on economic growth and foreign trade performance and how the distribution of the economic activity may change as the country opens up to foreign trade. Among the distinctive features embedded in the model, modeling of external scale economies, port efficiency and land-maritime transport costs provides an innovative way of dealing explicitly with theoretical issues related to integrated regional systems. In order to illustrate the role played by the quality of infrastructure and geography on the country‟s foreign and interregional trade performance, a set of simulations is presented where barriers to trade are significantly reduced. The relative importance of trade policy, port efficiency and land-maritime transport costs for the country trade relations and regional growth is then detailed and quantified, considering both short run as well as long run scenarios. A final set of simulations shed some light on the effects of liberal trade policies on regional inequality, where the manufacturing sector in the state of São Paulo, taken as the core of industrial activity in the country, is subjected to different levels of external economies of scale. Short-run core-periphery effects are then traced out suggesting the prevalence of agglomeration forces over diversion forces could rather exacerbate regional inequality as import barriers are removed up to a certain level. Further removals can reverse this balance in favor of diversion forces, implying de-concentration of economic activity. In the long run, factor mobility allows a better characterization of the balance between agglomeration and diversion forces among regions. Regional dispersion effects are then clearly traced-out, suggesting horizontal liberal trade policies to benefit both the poorest regions in the country as well as the state of São Paulo. This long run dispersion pattern, on one hand seems to unravel the fragility of simple theoretical results from recent New Economic Geography models, once they get confronted with more complex spatially heterogeneous (real) systems. On the other hand, it seems to capture the literature‟s main insight: the possible role of horizontal liberal trade policies as diversion forces leading to a more homogeneous pattern of interregional economic growth.

Impacto de propostas de redução de tarifas em bens não agrícolas (NAMA)

O objetivo deste estudo é avaliar, por meio de um modelo de equilíbrio geral computável, multi-setorial e multi-regional, os impactos de uma redução das tarifas dos bens não agrícolas sobre a economia brasileira, a partir da Fórmula Suíça, com diferentes coeficientes. O modelo de equilíbrio geral utilizado é o Global Trade Analysis Project (GTAP) e os cortes de tarifas foram estimados a partir de dados do MAcMap. Além dos impactos macroeconômicos e setoriais, testou-se a sensibilidade do modelo ao aumento das elasticidades de Armington e à implementação de liberalização tarifária agrícola.

Impactos econômicos das mudanças do PIS-COFINS utilizando um modelo de equilíbrio geral computável

Neste artigo é apresentada uma avaliação dos impacto da reforma tributária do PIS/PASEP e da COFINS, que passaram a ser coletados através de dois regimes associados aos fluxos domésticos (cumulativo e não cumulativo - misto) e a incidir sobre importações de bens e serviços. A metodologia adotada utiliza um modelo de Equilíbrio Geral Computável (CGE), adaptado para as novas características do sistema fiscal e especificado para simular os impactos sobre indicadores de bem-estar no Brasil. Estes impactos foram avaliados em duas etapas: a mudança do regime cumulativo para o novo regime tributário e a reforma completa. Os resultados mostram que esta reforma teria provocado deterioração dos indicadores macroeconômicos, de mercado de trabalho e de bem-estar.

On the use (fulness) of CGE modelling in trade negotiations and policy

This paper discusses a series of issues related to the use and different possible applications of CGE modelling in trade negotiations. The points addressed range from practical to methodological questions: when to use the models, what they provide the users and how far the model structure and assumptions should be explained to them, the complementary roles of partial and general equilibrium modelling, areas to be improved and data questions. The relevance of the modeller as the final decision maker in all these instances is also highlighted.

Tax reform under fiscal stress: a CGE analysis of the Brazilian tax reform

In spite of a general agreement over the distortion imposed by the current Brazilian tax system, attempts to reform it during the last decade have faced several restrictions to its implementation. Two of these restrictions were particular binding: a) fiscal adjustment restriction (public sector debt cannot increase), b) fiscal federalist restriction (revenues from individual states and municipalities cannot decrease). This paper focuses on a specific reform that overcomes in principle the fiscal federalist restriction. Using Auerbach and Kotlikoff (1987) model calibrated for the Brazilian economy, I analyze the short and long run macroeconomic effects of this reform subject to the fiscal adjustment restriction. Finally, I look at the redistributive effects of this reform among generations as a way to infer about public opinion’s reaction to the reform. The reform consists basically of replacing indirect taxes on corporate revenues, which I show to be equivalent to a symmetric tax on labor and capital income, by a new federal VAT. The reform presented positive macroeconomic effects both in the short and long run. Despite a substantial increase in the average VAT rate in the first years after the reform, a majority of cohorts experienced an increase in their lifetime welfare, being potentially in favour of the reform.
