Impacts of the proposals for tariff reductions in non-agricultural market access (Nama)

O Estudo Visa Avaliar os Impactos de Propostas Alternativas de Redução da Proteção Tarifária de Bens Não-Agrícolas Sobre a Economia Brasileira Usando um Modelo de Equilíbrio Geral Computável. Foram Simulados os Impactos da Implementação de Cortes Tarifários de Acordo com Diferentes Coeficientes para a Fórmula Suíça. as Simulações Foram Realizadas com o Modelo Gtap e Todos os Choques Tarifários Foram Calculados a Partir de Informações da Base de Dados Macmap. Além de Analisar Resultados Macroeconômicos e Setoriais, Também foi Testada a Sensibilidade dos Resultados em Relação ao Aumento das Elasticidades de Armington e À Ocorrência de uma Simultânea Liberalização de Tarifas Sobre Bens Agrícolas.

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

Tourism and poverty relief

This paper examines the issue of how tourism affects poverty in the context of the effects of tourism on an economy as a whole and on particular sectors within it. A framework for analysing the channels through which tourism affects different households is developed, and a computable general equilibrium model of the Brazilian economy is used to examine the economic impact and distributional effects of tourism in Brazil. It is shown that the effects on all income groups are positive. The lowest income households benefit from tourism but by less than some higher income groups. Policies that could redistribute greater shares of the revenue to the poor are considered.

Relações comerciais entre Brasil e China : uma análise de bem-estar a partir de um modelo de equilíbrio geral computável

O propósito deste trabalho é examinar possíveis ganhos de bem-estar provenientes de arranjos comerciais entre Brasil e China sob a ótica de um modelo de equilíbrio geral computável, o chamado “modelo GTAP” (sigla para Global Trade Analysis Project). Com base em uma descrição extensiva das estruturas econômicas e comerciais dos países e das Vantagens Comparativas de cada um deles, é possível simular acordos preferenciais de comércio e analisar os resultados de bem-estar por meio da medida de Variação Equivalente. Outro aspecto referente ao comércio sino-brasileiro que pode ser avaliado pela medida de bem-estar é o desalinhamento cambial dos dois países e as consequências deste para as transações comerciais entre ambos. Utilizando o mesmo ferramental anteriormente citado, o trabalho busca avaliar o impacto de tal desalinhamento no bem-estar dos países, uma vez que o câmbio seja corrigido via ajuste tarifário.

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.

Análise econômica da reforma fiscal do PIS e da COFINS: integrando um modelo de micro-simulação com um modelo de equilíbrio geral computável

Neste texto é apresentado o relatório final do projeto 561/06, “Análise Econômica da Reforma Fiscal do PIS-COFINS: Integrando um modelo de micro-simulação com um Modelo de Equilíbrio Geral Computável”. Essencialmente trata-se de uma extensão metodológica do projeto 461/04, visando um aprimoramento da quantificação dos impactos sobre indicadores de bem estar, particularmente pobreza e desigualdade. Além do modelo de Equilíbrio Geral, busca-se uma integração com um modelo de micro-simulação, baseado nas pesquisas domiciliares com o intuito de aprofundar e identificar o impacto que a reforma fiscal teve sobre indivíduos e famílias brasileiras, fazendo com estes sejam identificados com uma precisão muito maior, na medida em que a pesquisa anterior permitia apenas a identificação de um agrupamento representativo da população brasileira, enquanto esta permite a integração no modelo das amostras individuais presentes na PNAD. Os resultados apresentados são sensíveis a nova metodologia utilizada.

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.

Chronic Diseases: Chronic Diseases and Development 2 Health, agricultural, and economic effects of adoption of healthy diet recommendations

Transition to diets that are high in saturated fat and sugar has caused a global public health concern as the pattern of food consumption is a mayor modifiable risk factor for chronic non-communicable diseases Although agri food systems are intimately associated with this transition, agriculture and health sectors are largely disconnected in their priorities policy, and analysis with neither side considering the complex inter relation between agri trade patterns of food consumption health, and development We show the importance of connection of these perspectives through estimation of the effect of adopting a healthy diet on population health, agricultural production trade the economy and livelihoods, with a computable general equilibrium approach on the basis of case studies from the UK and Brazil we suggest that benefits of a healthy diet policy will vary substantially between different populations, not only because of population dietary intake but also because of agricultural production trade and other economic factors

A mixed methods inquiry into the political economy of agriculture and rural areas in Lebanon

The present work, then, is concerned with the forgotten elements of the Lebanese economy, agriculture and rural development. It investigates the main problematic which arose from these forgotten components, in particular the structure of the agricultural sector, production technology, income distribution, poverty, food security, territorial development and local livelihood strategies. It will do so using quantitative Computable General Equilibrium (CGE) modeling and a qualitative phenomenological case study analysis, both embedded in a critical review of the historical development of the political economy of Lebanon, and a structural analysis of its economy. The research shows that under-development in Lebanese rural areas is not due to lack of resources, but rather is the consequence of political choices. It further suggests that agriculture – in both its mainstream conventional and its innovative locally initiated forms of production – still represents important potential for inducing economic growth and development. In order to do so, Lebanon has to take full advantage of its human and territorial capital, by developing a rural development strategy based on two parallel sets of actions: one directed toward the support of local rural development initiatives, and the other directed toward intensive form of production. In addition to its economic returns, such a strategy would promote social and political stability.

Calibrating a CGE model with NTBs that Incorporates Standard Models of Modern Trade Theory

We propose a way to incorporate NTBs for the four workhorse models of the modern trade literature in computable general equilibrium models (CGEs). CGE models feature intermediate linkages and thus allow us to study global value chains (GVCs). We show that the Ethier-Krugman monopolistic competition model, the Melitz firm heterogeneity model and the Eaton and Kortum model can be defined as an Armington model with generalized marginal costs, generalized trade costs and a demand externality. As already known in the literature in both the Ethier-Krugman model and the Melitz model generalized marginal costs are a function of the amount of factor input bundles. In the Melitz model generalized marginal costs are also a function of the price of the factor input bundles. Lower factor prices raise the number of firms that can enter the market profitably (extensive margin), reducing generalized marginal costs of a representative firm. For the same reason the Melitz model features a demand externality: in a larger market more firms can enter. We implement the different models in a CGE setting with multiple sectors, intermediate linkages, non-homothetic preferences and detailed data on trade costs. We find the largest welfare effects from trade cost reductions in the Melitz model. We also employ the Melitz model to mimic changes in Non tariff Barriers (NTBs) with a fixed cost-character by analysing the effect of changes in fixed trade costs. While we work here with a model calibrated to the GTAP database, the methods developed can also be applied to CGE models based on the WIOD database.

Non-tariff barriers, integration and the transatlantic economy

We examine the potential impact of TTIP through trade-cost reductions, applying a mix of econometric and computational methods to develop estimates of the benefits (and costs) for the EU, United States, and third countries. Econometric results point to an approximate 80% growth in bilateral trade with an ambitious trade agreement. However, at the same time, computable general equilibrium (CGE) estimates highlight distributional impacts across countries and factors not evident from econometrics alone. Translated through our CGE framework, while bilateral trade increases roughly 80%, there is a fall of about 2.5% in trade with the rest of the world in our central case. The estimated gains in annual consumption range between 1% and 2.25% for the United States and EU, respectively. A purely discriminatory agreement would harm most countries outside the agreement, while the direction of third-country effects hinges critically on whether NTB reductions end up being discriminatory or not. Within the United States and EU, while labour gains across skill categories, the impact on farmers is mixed.

An Economic Derivation on Trade Coefficients under the Framework of Multi-regional I-O Analysis

The gravity model, entropy model, potential type model and others like these have been adopted to formulate interregional trade coefficients under the framework of Multi-Regional I-O (MRIO) analysis. Since most of these models are based upon analogies in physics or on statistical principles, they do not provide a theoretical explanation from the view of a firm's or individual's rational and deterministic decision making. In this paper, according to the deterministic choice theory, not only is an alternative formulation of the trade coefficients presented, but also a discussion of an appropriate definition for purchasing prices indices. Since this formulation is consistent with the MRIO system, it can be employed as a useful model-building tool in multi-regional models such as the spatial CGE model.
