Sistemas de regulação do comércio internacional em confronto: o marco dos estados e o marco das transnacionais

This article revisits a past article by the authors in which they propose a new methodology for analyzing trade issues, cross-cutting through the three ―layers‖ of international trade regulation: so-called multisystem of trade regulation. In this text the authors include another approach to international trade regulation studies, proposing a better understanding of the influence of transnational enterprises in the shaping of modern internal trade. In this sense, the transnationals are not only influencing international trade regulation through lobbying in traditional fora (especially in plurilateral and preferential trade agreements), but they are also becoming sources of their own private regulations, particularly regarding private standards. In this sense, the study of international trade regulation must take into account the activities and interests of these indispensible actors, critically analyzing the differences between the regulatory logic of states against the one keen to transnationals

Trade and poverty in latin american countries: conceptual and methodological challenges

This paper addresses topics - either relevant or confusing or needing more attention - related to measuring the trade and poverty nexus. It sheds a critical light on the existing material and suggests needed research lines. It starts with questions akin to the LAC realities; then, keeping this view, general methodological issues are also examined. In a broader perspective, further ideas for the research agenda are formulated. The main conclusion is that relevant findings still demand considerable efforts. Moreover, the Information-measurement-model-evaluation paradigm is not enough, policy guidelines being usually too general. In LAC, it must be extended and deepened, accounting more for the heterogeneity of cases, including, whenever possible, the physical constraints and incorporating new ways of integrating both the local and global perspectives. Other aspects, like the role of specific juridical measures, should play a role. How all this can be combined into more encompassing evaluations remains open

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.

Regulation issues in the banking industry

Esta tese tem por objetivo examinar os fatores que direcionam o processo decisório de estrutura de capital/investimento do banco e avaliar a efetividade da intervenção regulatória no Brasil. O trabalho está divido em três capítulos. No primeiro capítulo, apresenta-se, de forma sistematizada, arcabouço teórico e evidências empíricas na literatura para explicar o comportamento da firma bancária, fortemente regulada, em suas decisões de financiamento e investimento. Além disso, descreve-se a evolução dos padrões internacionais de regulação prudencial de capital, desde a publicação do primeiro Acordo de Basiléia até as medidas iniciais de Basiléia III, apresentando também o contexto normativo no Brasil. No segundo capítulo, por meio de modelo dinâmico da teoria de trade-off, analisam-se os determinantes do buffer de capital dos bancos brasileiros entre 2001 e 2009. Os resultados sugerem que: (i) o requerimento regulatório de capital e os custos de ajustes de capital influenciam nas decisões dos bancos; (ii) as avaliações da autoridade de supervisão bancária impacta os colchões de capital; (iii) a disciplina de mercado pode não ser efetiva em aumentar a solvência dos bancos; e (iv) existe uma relação negativa entre o colchão de capital e o ciclo de negócios que pode representar uma gestão procíclica de capital dos bancos. Por fim, no terceiro capítulo, utiliza-se metodologia proprietária dos escores das instituições conferidos pela autoridade supervisora (CAMEL), para apresentar evidências de que as pressões regulatória e de supervisão no Brasil induzem os bancos a realizarem ajustes de curto prazo relativamente menores na alavancagem e, principalmente, no risco do portfólio.

Emissões de eurobonds tem impacto no cupom cambial?

Este estudo tem por objetivo estimar o impacto do fluxo de emissões corporativas brasileiras em dólar sobre o cupom cambial. Podemos entender o cupom cambial, sob a ótica da Paridade Coberta da Taxa de Juros, como resultado de dois componentes: Taxa de juros externa (Libor) e Risco País. Desvios adicionais sobre a Paridade podem ser explicados por diversos fatores como custos de transação, liquidez, fluxos em transações de arbitragem de empresas financeiras ou não-financeiras, etc. Neste contexto, os fluxos de arbitragem ocorrem quando é possível para uma empresa brasileira captar recursos no mercado externo e internar estes recursos no Brasil encontrando uma taxa final de captação em reais inferior à de sua captação local (via debêntures, notas financeiras, empréstimos, CDB’s, etc) incluindo todos os custos. Quando há condições necessárias a este tipo de operação, o efeito pode ser visto no mercado de FRA de cupom cambial da BM&F, através de um fluxo anormal de doadores de juros. Testes não-paramétricos (Wilcoxon-Mann-Whitney, Kruskal-Wallis e Van der Waerden) e a metodologia de estudo de eventos detectaram comportamento anormal no mercado de FRA de cupom cambial frente aos eventos aqui considerados como emissões de eurobonds de empresas brasileiras, excluindo o efeito do risco soberano, medido pelo CDS Brasil e considerando nulo o risco de conversibilidade no período, após análise do diferencial entre NDF onshore e offshore. Para estimação do impacto das emissões sobre o FRA de cupom cambial foram utilizados dois modelos, AR-GARCH e OLS com correção de Newey-West, e os resultados mostraram que as emissões causam fechamento de 2 a 5 bps no FRA de cupom cambial, dependendo do vencimento da emissão e do modelo avaliado. Sob a mesma metodologia, concluímos de cada USD 100 milhões de emissões são responsáveis por, em média, 1 bps de fechamento no FRA de cupom cambial, tudo mais constante.

Alocação dinâmica ótima com momentos de ordem superior para a estratégia de carry trade

O objetivo do presente trabalho é verificar se, ao levar-se em consideração momentos de ordem superior (assimetria e curtose) na alocação de uma carteira de carry trade, há ganhos em relação à alocação tradicional que prioriza somente os dois primeiros momentos (média e variância). A hipótese da pesquisa é que moedas de carry trade apresentam retornos com distribuição não-Normal, e os momentos de ordem superior desta têm uma dinâmica, a qual pode ser modelada através de um modelo da família GARCH, neste caso IC-GARCHSK. Este modelo consiste em uma equação para cada momento condicional dos componentes independentes, explicitamente: o retorno, a variância, a assimetria, e a curtose. Outra hipótese é que um investidor com uma função utilidade do tipo CARA (constant absolute risk aversion), pode tê-la aproximada por uma expansão de Taylor de 4ª ordem. A estratégia do trabalho é modelar a dinâmica dos momentos da série dos logartimos neperianos dos retornos diários de algumas moedas de carry trade através do modelo IC-GARCHSK, e estimar a alocação ótima da carteira dinamicamente, de tal forma que se maximize a função utilidade do investidor. Os resultados mostram que há ganhos sim, ao levar-se em consideração os momentos de ordem superior, uma vez que o custo de oportunidade desta foi menor que o de uma carteira construída somente utilizando como critérios média e variância.

A cross-country study on trade credit supply and financial crisis

O objetivo deste trabalho de pesquisa é investigar a oferta de crédito comercial durante períodos de crise financeira em seis países diferentes: Brasil, França, Alemanha, Itália, Espanha e Reino Unido, foram utilizadas informações de empresas de capital aberto entre 2000 e 2011. A literatura internacional documenta que durante o pico de crises financeiras a oferta de crédito comercial aumenta pois as companhias usam o crédito comercial como substituto e/ou complemento ao crédito bancário, apesar de após o momento de pico esta oferta diminui significantemente porque as empresas enfrentam problemas de liquidez causado por escassez de crédito. Mesmo que somente existam evidências pontuais de que a oferta de crédito comercial aumentou durante a crise financeira global de 2008, o efeito pós-crise é perceptível durante a crise Europeia de 2011, pois as empresas europeias diminuíram a oferta de crédito comercial, também evidenciando que estas companhias estavam confrontando problemas de administração de liquidez. Em relação ao uso de crédito comercial como ferramenta de transmissão de capital, nenhuma evidência foi encontrada para provar sua existência em tempo de crise financeira.

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.

Agreements and disputes over non-tariff measures

In trade agreements, governments can design remedies to ensure compliance (property rule) or to compensate victims (liability rule). This paper describes an economic framework to explain the pattern of remedies over non-tariff restrictions—particularly domestic subsidies and nonviolation complaints subject to liability rules. The key determinants of the contract form for any individual measure are the expected joint surplus from an agreement and the expected loss to the constrained government. The loss is higher for domestic subsidies and nonviolations because these are the policies most likely to correct domestic distortions. Governments choose property rules when expected gains from compliance are sufficiently high and expected losses to the constrained country are sufficiently low. Liability rules are preferable when dispute costs are relatively high, because inefficiencies in the compensation process reduce the number of socially inefficient disputes filed.

On the effects of non-tariff measures on Brazilian exports

This article proposes an alternative methodology for estimating the effects of non-tariff measures on trade flows, based on the recent literature on gravity models. A two-stage Heckman selection model is applied to the case of Brazilian exports, where the second stage gravity equation is theoretically grounded on the seminal Melitz model of heterogeneous firms. This extended gravity equation highlights the role played by zero trade flows as well as firm heterogeneity in explaining bilateral trade among countries, two factors usually omitted in traditional gravity specifications found in previous literature. Last, it also proposes a economic rationale for the effects of NTM on trade flows, helping to shed some light on its main operating channels under a rather simple Cournot’s duopolistic competition framework.

Addressing important econometric issues on how to construct theoretical based exchange rate misalignment estimates

Exchange rate misalignment assessment is becoming more relevant in recent period particularly after the nancial crisis of 2008. There are di erent methodologies to address real exchange rate misalignment. The real exchange misalignment is de ned as the di erence between actual real e ective exchange rate and some equilibrium norm. Di erent norms are available in the literature. Our paper aims to contribute to the literature by showing that Behavioral Equilibrium Exchange Rate approach (BEER) adopted by Clark & MacDonald (1999), Ubide et al. (1999), Faruqee (1994), Aguirre & Calderón (2005) and Kubota (2009) among others can be improved in two following manners. The rst one consists of jointly modeling real e ective exchange rate, trade balance and net foreign asset position. The second one has to do with the possibility of explicitly testing over identifying restrictions implied by economic theory and allowing the analyst to show that these restrictions are not falsi ed by the empirical evidence. If the economic based identifying restrictions are not rejected it is also possible to decompose exchange rate misalignment in two pieces, one related to long run fundamentals of exchange rate and the other related to external account imbalances. We also discuss some necessary conditions that should be satis ed for disrcarding trade balance information without compromising exchange rate misalignment assessment. A statistical (but not a theoretical) identifying strategy for calculating exchange rate misalignment is also discussed. We illustrate the advantages of our approach by analyzing the Brazilian case. We show that the traditional approach disregard important information of external accounts equilibrium for this economy.

Citizens and the future of multilateralism in a polycentric world at 2030: the perspectives of emerging countries for the trading system: the impasse of WTO, the trends of mega agreements, the logic of value chains and the advent of consumers concerns on international trade

A new paradigm is modeling the World: evolutionary innovations in all fronts, new information technologies, huge mobility of capital, use of risky financial tools, globalization of production, new emerging powers and the impact of consumer concerns on governmental policies. These phenomena are shaping the World and forcing the advent of a new World Order in the Multilateral Monetary, Financial, and Trading System. The effects of this new paradigm are also transforming global governance. The political and economic orders established after the World War and centered on the multilateral model of UN, IMF, World Bank, and the GATT, leaded by the developed countries, are facing significant challenges. The rise of China and emerging countries shifted the old model to a polycentric World, where the governance of these organizations are threatened by emerging countries demanding a bigger participation in the role and decision boards of these international bodies. As a consequence, multilateralism is being confronted by polycentrism. Negotiations for a more representative voting process and the pressure for new rules to cope with the new demands are paralyzing important decisions. This scenario is affecting seriously not only the Monetary and Financial Systems but also the Multilateral Trading System. International trade is facing some significant challenges: a serious deadlock to conclude the last round of the multilateral negotiation at the WTO, the fragmentation of trade rules by the multiplication of preferential and mega agreements, the arrival of a new model of global production and trade leaded by global value chains that is threatening the old trade order, and the imposition of new sets of regulations by private bodies commanded by transnationals to support global value chains and non-governmental organizations to reflect the concerns of consumers in the North based on their precautionary attitude about sustainability of products made in the World. The lack of any multilateral order in this new regulation is creating a big cacophony of rules and developing a new regulatory war of the Global North against the Global South. The objective of this paper is to explore how these challenges are affecting the Tradinge System and how it can evolve to manage these new trends.
