A tendência à sobreapreciação da taxa de câmbio

Nos países em desenvolvimento há uma tendência à sobrevalorização da taxa de câmbio. Existem duas causas estruturais: a doença holandesa e a atração que altos lucros e taxas de juros nos países em desenvolvimento exercem sobre capitais externos, e quatro causas políticas: a política do crescimento com poupança externa, o controle da inflação através de uma “âncora”, cambial, a política de “aprofundamento de capital”, e o populismo cambial. O país deverá neutralizar esta tendência para poder ter um crescimento rápido, ou sofrerá crises cíclicas de balanço de pagamento

Política cambial e macroeconomia do desenvolvimento

Alguns autores têm chamado a atenção para a importância da administração cambial nos processos de desenvolvimento econômico no que vem sendo conhecido como um ¿development approach¿ para taxas de câmbio. O nível do câmbio real teria forte impacto na acumulação de capital na medida em que afetaria as trajetórias de consumo, investimento e poupança agregados de uma economia via definição do nível do salário real. O setor de bens comercializáveis não tradicional estimulado por um câmbio competitivo destacar-se-ia pelo seu dinamismo e potencial de inovações tecnológicas, contribuindo para aumentos de produtividade necessários ao processo de desenvolvimento econômico. Estímulos ao setor de exportações contribuiriam também para a redução da vulnerabilidade a crises externas. Inúmeros estudos têm destacado a ocorrência de crises no balanço de pagamentos por problemas de sobrevalorização cambial ou desalinhamento. Com o objetivo de contribuir para essa discussão, o trabalho a ser apresentado trata das relações existentes entre nível do câmbio real e o processo de desenvolvimento econômico. Tem como objetivo mais específico analisar a hipótese de que haveria uma relação negativa entre nível do câmbio real e taxas de crescimento per capita. Câmbios reais relativamente desvalorizados seriam benéficos para processos de desenvolvimento econômico enquanto que níveis excessivos de apreciação cambial seriam nocivos.

A taxa de câmbio no centro da teoria do desenvolvimento

This paper presents the main ideas of structuralist development macroeconomics – the theory behind new developmentalism. Its focus is on the exchange rate that is positioned for the first time in the core of development economics. Economic theory usually views the exchange rate as a short term problem to be discussed in open macroeconomics. Structuralist development macroeconomics argues that there is in developing countries a tendency to the cyclical overvaluation of the exchange rate caused by the lack of neutralization of the Dutch disease and by excessive capital inflows. In consequence it views the exchange rate as chronically overvalued, and, for that reason, a major obstacle to economic growth. In the development process, the exchange rate has the role of light switch that connects or disconnects the national business enterprises utilizing technology in the world state of the art from world markets

Exchange rate policies, patterns of specialization and economic development: theory and evidence in developing countries

The objectives of this paper are twofold. First, it intends to provide theoretical elements to analyze the relation between real exchange rates and economic development. Our main hypothesis is very much in line with the Dutch disease literature, and states that competitive currencies contribute to the existence and maintenance of the anufacturing sector in the economy. This, in turn, brings about higher growth rates in the long run, given the existence of increasing returns in the industrial sector, and its importance in generating echnological change and increasing productivity in the overall economy. The second objective of this paper is empirical. It intends to analyze examples of successful exchange rate policies, such as Chile and Indonesia in the eighties, as a benchmark for comparison with countries where currency overvaluation has taken place, such as Brazil. In the latter case, the local currency is being inflated by large capital inflows, due to high domestic interest rates and to a boom in demand and prices of commodities in the international markets. It will be argued that the industrial sector bears most of the burden when the currency appreciates, and that Brazil risks at deindustrialization if there are no changes in the exchange rate regime

Does humor work in advertising of pharmaceutical products?

This thesis aims to evaluate whether humorous television commercials (TVCs) work for non-prescription drugs, known as “over-the-counter” (OTC). The construct humor in advertising is controversial since it involves complex and broad typology, and depends on the audience characteristics. Several studies within different product categories indicated that some consumer goods are better suited for humorous TVCs, while others, such as OTC drugs, may not take advantage from it. Paradoxically, drug announcers spend billions of dollars worldwide in humorous OTC ads. An experiment with real consumers was designed as between-and-within-subjects, to test three hypotheses. Sixty women were exposed to pairs of humorous and non-humorous TVCs, for each of the three drug categories (analgesics, vitamins, and laxatives). We used fictional brand names and real ads, and measured four dependant variables: attitude toward the advertising (AAD), attitude toward the brand (ABR), purchase intention (PI), and brand choice (BC), after subjects being exposed to manipulations of two independent variables: humorous vs. non-humorous TV commercials, for the drug categories. Conditional logit model confirmed that humor does not help to persuade respondents, whose choices, attitudes, and purchase intention were less favorable with humorous TVCs, in comparison to non-humorous executions. Future research is presented regarding marketing for pharmaceutical products.

Structuralist macroeconomics and new developmentalism

This paper, first, presents some basic ideas and models of a structuralist development macroeconomics that complements and actualizes the thought of structuralist development economics that was dominant between the 1940s and the 1960s including in the World Bank. The new approach focus on the relation between the exchange rate and economic growth, and develops three interrelated models: the tendency to the overvaluation of the exchange, the critique of growth with foreign savings, and a model of the Dutch disease based on the existence of two exchange rate equilibriums: the “current” and the “industrial” equilibrium. Second, it summarizes “new developmentalism” – a sum of growth policies based on these models and on the experience of fast growing Asian countries

Brazil’s 35 years-old quasi-stagnation: facts and theory

Brazil is growing around 1% per capita a year from 1981; this means for a country that is supposed to catch up, quasi-stagnation. Four historical new facts explain why growth was so low after the Real Plan: the reduction of public savings, and three facts that reduce private investments: the end of the unlimited supply of labor, a very high interest rate, and the 1990 dismantling of the mechanism that neutralized the Dutch disease, which represented a major competitive disadvantage for the manufacturing industry. New-developmental theory offers an explanation and two solutions for the problem, but does not underestimate the political economy problems involved

How to neutralize the adverse developmental effects of the Dutch disease?

This paper addresses the subject of the adverse developmental effects of the Dutch disease: the theory, the experience of Latin America over the last decade, and the economic policy management issues on what to do about it.
