The distortion of currencies misalignments on trade Instruments: or why currencies wars are not over

The negotiations of mega agreements between the US and the Pacific countries (TPP) and between the US and the EU (TTIP) are raising the attention of experts on international trade law and economics. TPP and TTIP are proclaimed to be the designers of the rules for the XXI Century. Old trade instruments such as tariffs are said to be no more important for TTIP because tariffs are negligible among those partners but significant to for TPP. Another relevant agreement in negotiation is between the EU and Mercosul, where tariffs are the most important issue in discussion. The main purpose of this paper is to shows that tariff are important for all these agreements, not because of its nominal value, but because the impacts of exchange rate misalignments on tariffs are so significant that all concessions can be distorted by overvalued and by devaluated currencies. The article is divided into several sections: the first gives an introduction to the issue; the second explains the methodologies used to determine exchange rate misalignments and also presents some results for Brazil, US and China; the third summarizes the methodology applied to calculate the impacts of exchange rate misalignments on the level of tariff protection through an exercise of “misalignment tariffication” and examines the effects of exchange rate variations on tariffs and their consequences for the multilateral trading system; the fourth creates a methodology to estimate exchange rates against a basket of currencies (a virtual currency of the World) and a proposal to deal with persistent and significant misalignments related to trade rules. The fifth presents some estimates for the main PTAs. The conclusions are present in the last section

O “elo perdido” entre a organização mundial do comércio e o fundo monetário internacional

One of the main objectives of the Bretton Woods negotiations was to guarantee the firm control over competitive exchange rate devaluations, which had worsened the effects of the economic crisis of the 1930s. The par value exchange rate system was thus created, representing a link between the international financial system and the international trading system, guaranteeing, to the latter, the neutrality of the currency issue. The present article analyses how the institutional revolutions suffered by the IMF ended up representing the loss of this link and discusses its consequences to the WTO

Essays in applied econometrics

Using a unique dataset on Brazilian nominal and real yield curves combined with daily survey forecasts of macroeconomic variables such as GDP growth, inflation, and exchange rate movements, we identify the effect of surprises to the Brazilian interbank target rate on expected future nominal and real short rates, term premia, and inflation expectations. We find that positive surprises to target rates lead to higher expected nominal and real interest rates and reduced nominal and inflation term premia. We also find a strongly positive relation between both real and nominal term premia and measures of dispersion in survey forecasts. Uncertainty about future exchange rates is a particularly important driver of variations in Brazilian term premia.

Balance of payments dominance: its implications for macroeconomic policy

This paper defines “balance of payments dominance” as a macroeconomic regime in which the short-term macroeconomic dynamics is essentially determined by external shocks, positive or negative. It argues that this is the predominant regime in emerging and developing countries. Trade shocks play an important role but the major procyclical shocks are associated with boom-bust cycles in external financing. Policy challenges are associated not only with the management of such shocks but also with the need to enhance the space for countercyclical macroeconomic policies, as boom-bust cycles tend to pressure macroeconomic policies to behave in a procyclical way. Under these conditions, the best bet is to design policies to reduce external vulnerabilities through a mix of administered exchange rate policies, very active foreign exchange reserve management, reduced reliance on external borrowing, and macroprudential regulations, including those directly affecting capital flows. Countercyclical fiscal policy can also play a role but face strong economic and political economy challenges.

Europe’s financial crisis: the Euro’s flawed design and the consequences of lack of a government banker

This paper argues the euro zone requires a government banker that manages the bond market and helps finance country budget deficits. The euro solved Europe’s problem of exchange rate speculation by creating a unified currency managed by a single central bank, but in doing so it replaced the exchange rate speculation problem with bond market speculation. Remedying this requires a central bank that acts as government banker and maintains bond interest rates at sustainable levels. Because the euro is a monetary union, this must be done in a way that both avoids favoring individual countries and avoids creating incentives for irresponsible country fiscal policy that leads to “bail-outs”. The paper argues this can be accomplished via a European Public Finance Authority (EPFA) that issues public debt which the European Central Bank (ECB) is allowed to trade. The debate over the euro’s financial architecture has significant political implications. The current neoliberal inspired architecture, which imposes a complete separation between the central bank and public finances, puts governments under continuous financial pressures. That will make it difficult to maintain the European social democratic welfare state. This gives a political reason for reforming the euro and creating an EPFA that supplements the economic case for reform.

Notes on cyclical tendency to the overvaluation of the real

This note addresses the question “To what extent financial regulation in Brazil was effective in neutralizing the tendency to the overvaluation of the exchange rate in Brazil since the 1994 Real Plan?” Aiming at answering this question, this note is organized as follows: after this short introduction, we briefly describe the Brazilian exchange rate behavior after the Real Plan, emphasizing its key role in keeping prices stable. In section 3, the recent measures adopted by the Brazilian Central Bank (BCB) aiming at avoiding the overvaluation of real will be summarized. In section 4, we argue in favor of a new policy mix that could avoid overvaluation of the currency. Finally, some issues will be raised in order to effectively neutralize the overvaluation of real.

Balance of payments dominance : its implocations for macroeconomic policy

It argues that this is the predominant regime in emerging and developing countries. Trade shocks play an important role but the major procyclical shocks are associated with boom-bust cycles in external financing.

Under these conditions, the best bet is to design policies to reduce external vulnerabilities through a mix of administered exchange rate flexibility, very active foreign exchange reserve management, reduced reliance on external borrowing, and macroprudential regulations, including those directly affecting capital flows. Countercyclical fiscal policy can also play a role but face strong economic and political economy challenges.

Macroeconomic constraints to growth of Brazilian economy diagnosis and some policy proposals

The recent process of accelerated expansion of the Brazilian economy was driven by exports and fixed capital formation. Although the pace of growth was more robust than in the 1990´s, we can still witness the existence of certain macroeconomic constraints to its continuation in the long run such as, for instance, the exchange rate overvaluation in particular since 2005, and in general the modus operandi of monetary policy. Such constraints may jeopardize the sustainability of the current pace of growth. Therefore, we argue that Brazil still lies in a trap made up of high interest and low exchange rates. The elimination of the exchange rate misalignment would bring about a great increase in the rate of interest, which on its turn would impact negatively upon investment and hence upon the sustainability of long run economic growth. We outline a set of policy measures to eliminate such a trap, in particular, the adoption of an implicit target for the exchange rate, capital controls and the abandonment of the present regime of inflation targeting. Recent events seem to go in this direction.

A structuralist Philips curve

This paper presents a structuralist model of the Philips curve and applies it to the US and Brazilian economies. The theoretical model starts from a simple markup rule to build a Philips curve based on the assumptions that firms have a desired rate of profit and wokers have a target real wage. Inflation expectations are modeled in terms of current inflation and the governments’ target, and the model shows that relative prices can have both a short-run and long-run influence on inflation. When applied to the US, the structuralist Philips curve results in a nonlinear model in which there are two steady states for inflation, and where the wageshare of income becomes the main instrument to drive inflation to the governments’ target. When applied to Brazil, the structuralist Philips curve reveals a nonlinear relationship between long-run inflation and the real exchange rate, so that the same inflation target can be consistent with more than one value of the exchange rate. The main conclusion of the paper is that a structuralist specification of the Philips curve is a useful instrument to model many macroeconomic topics as well as alternative theoretical closures.

Relações internacionais: o comércio exterior do Brasil e Rio Grande do Norte no período de 1999 a 2008

The period post-war promoted several changes in relations economic, political and social world. Since then, a new division international of labor has delineated, with the great growth of Asian countries. In the field of international relations, the world still appears to transition is not completed because the old institutions were not replaced by new ones and the power of the United States as a major capitalist country remains unshaken, even with the emergence and strengthening of new economic global blocs. With globalization, Brazil emerges with more intensity in the face of new issues global, although its share in transactions trade global hasn‟t changed accordingly. In this sense, the objective of this dissertation is to examine, in a descriptive and critical the development of international relations and trade of Brazil and Rio Grande do Norte with the main blocs in the world from 1999 to 2008. As a secondary objective: to identify the assumptions theoretical that underpinned the decisions governments of the FHC and Lula, in particular, the interference of these terms in international relations and foreign trade. Adopted as the procedure methodological the literature review of the subject, as well as collection and processing of the data of foreign trade. During the Cardoso government has undergone the substantial growth in imports, as part of the economic policy of anti-inflationary, generating large deficits trade. From the first to the second term, with the inflection of exchange rate policy the country has resumed surpluses trade. The choice of government of the autonomy participation increased the relative share of the traditional blocks in total foreign trade and reduced the share of MERCOSUL. In the Lula government, there is the maintenance of some elements of the economic policy of the previous government and the partial shift in the conduct of foreign policy, with the option of autonomy through diversification, raising its stake on the blocks and other emerging countries in total foreign trade Brazilian and reducing the contribution of the traditional blocks such as NAFTA and the European Union. A trend observed in the previous government and deepened in the Lula government was the growth in commodity exports and the decline of manufactured products, confirming the model of conservative insertion of Brazilian exports. The Rio Grande do Norte followed the trend Brazilian in the growth of foreign trade, including in participating conservative, given that the products exported by the state are basically coming from horticulture irrigated and agribusiness. However, in the aspect of destination export, the state followed trajectory distinct from that in the Lula government, with the deepening of trade relations with traditional blocks, especially with the European Union and NAFTA

Comparação das respostas fisiológicas entre diferentes testes funcionais em obesos

obesity affects rightly functional capacity diminishing the cardiovascular system efficiency and oxygen uptake (VO2). Field tests, such as, Incremental Shuttle Walking Test (ISWT) and Six Minute Walk Test (6MWT) has been employed as alternative of Cardiopulmonary Exercise Test (CPX), to functional assessing for conditions which transport of oxygen to peripheral is diminished. Nevertheless, the knowing about metabolic variables response in real time and it comparing among different maximal and submaximal tests in obese is absent. Aim: to compare cardiopulmonary, metabolic response during CPX, ISWT and 6MWT and to analyse it influence of adiposity markers in obese. Material e Method: crosssectional, prospective study. Obese included if: (BMI>30Kg/m2; FVC>80%), were assessed as clinical, anthropometric (BMI, body adiposity index-BAI, waist-WC, hip- HC and neck-NC circumferences) and spirometry (forced vital capacity-FVC, Forced expiratory volume-1°second-FEV1, maximal voluntary ventilation-MVV) variables. Obese performed the sequence of tests: CPX, ISWT and 6MWT. Throughout tests was assessed breath-by-breath by telemetry system (Cortex-Biophysik-Metamax3B) variables; oxygen uptake on peak of activity (VO2peak); carbon dioxide production (VCO2); Volume Expiratory (VE); ventilatory equivalents for VO2 (VE/VO2) and CO2 (VE/VCO2); respiratory exchange rate (RER) and perceived effort-Borg6-20). Results: 15 obese (10women) 39.4+10.1years, normal spirometry (%CVF=93.7+9.7) finished all test. They have BMI (43.5+6.6kg/m2) and different as %adiposity (BAI=50.0+10.5% and 48.8+16.9% respectively women and men). Difference of VO2ml/kg/min and %VO2 were finding between CPX (18.6+4.0) and 6MWT (13.2+2.5) but not between ISWT (15.4+2.9). Agreement was found for ISWT and CPX on VO2Peak (3.2ml/kg/min; 95%; IC-3.0 9.4) and %VO2 (16.4%). VCO2(l/min) confirms similarity in production for CPX (2.3+1.0) and ISWT (1.7+0.7) and difference for 6MWT (1.4+0.6). WC explains more the response of CPX and ISWT than other adiposity markers. Adiposity diminishes 3.2% duration of CPX. Conclusion: ISWT promotes similar metabolic and cardiovascular response than CPX in obese. It suggesting that ISWT could be useful and reliable to assess oxygen uptake and functional capacity in obese

Taxa de câmbio e preços de exportação no Brasil: avaliação empírica dos coeficientes de pass-through setoriais

Este trabalho analisa, de forma empírica, no período 1995-2005, os impactos de variações cambiais sobre os preços de exportação no Brasil, desagregados setorialmente, levando em consideração a inserção externa da economia em um contexto de ampliação da internacionalização e reestruturação produtiva. O cálculo dos coeficientes de pass-through é complementado por um exercício de análise fatorial, com o objetivo de verificar se é possível encontrar padrões setoriais definidos. Os resultados indicam maiores repasses em setores produtores de bens de menor conteúdo tecnológico em que o Brasil possui posição comercial relativamente forte, ao passo que parte dos setores produtores de manufaturados apresenta coeficientes de repasse cambial reduzido.

Kinetics and mechanism of the forward and reverse reactions between N,N′-dimethyl-4,4′-bipyridinium and hexacyanoferrate(II)

The kinetics of the hexacyanoferrate(III)-N,N′-dimethyl-4,4′-bipyridinium radical (MV+) reaction was studied by a laser flash photolysis technique. The radical was generated, in the presence of Fe(CN)6 3-, by quenching the excited state *Ru(bpy)3 2+ with MV2+. The second-order rate constant for the Fe(CN)6 3--MV+ reaction is (7.6 ± 0.5) × 109 M-1 s-1 at 23°C and ionic strength 0.10 M. Comparison with the rate constants calculated for the diffusion-controlled reaction (4.7 × 109 M-1 s-1) and the activation-controlled reaction (5.2 × 1012 M-1 s-1, on the basis of self-exchange rate constants of 8.0 × 105 M-1 s-1 and 1.9 × 104 M-1 s-1 for the MV2+/+ and Fe(CN)6 3-/4- couples, respectively) leads to the conclusion that the Fe(CN)6 3--MV+ reaction is diffusion controlled. The rate constant for the Fe(CN)6-MV2+ reaction, calculated from the rate constant for the Fe(CN)6 3--MV+ reaction and the appropriate equilibrium constant, is 2.4 × 10-5 M-1 s-1 at 23°C and ionic strength 0.10 M. Microscopic reversibility considerations require that the Fe(CN)6 4--MV2+ reaction be controlled by the dissociation of the successor complex Fe(CN)6 3-|MV+. The thermal and optical electron transfers in the ion pair Fe(CN)6 4-|MV2+ and in related systems are analyzed and discussed. © 1982 American Chemical Society.

The Real Plan: Stabilization and destabilization

The paper analyzes Brazil's Real Plan, an exchange-rate based stabilization program, implemented in 1994, which mixed a spectacular price stabilization with some serious macroeconomic destabilization. The paper focuses on two of these imbalances: the consumption boom and the financial destabilization; showing that the former represented nothing the reverse side of a collapsed investment boom, which, in turn, led to the financial (banking) crisis. We hold that these instabilities were produced by a policy arrangement in which monetary and fiscal policies alone had to compensate for a largely appreciated, almost fixed, exchange rate anchor.
