New evidence on trade liberalization and productivity growth

Although the subject of a large number of studies, the debate on the links between trade reform and productivity growth is still unresolved and most studies at the micro level have not been able to establish a relationship between the two phenomena. Brazil provides a natural experiment to study this issue that is seldom available: it was one of the closest economies in the world until 1988, when trade reform was launched, and intra-industry data are available on an annual basis before, during and after liberalization. Using a panel of industry sectors this paper tests and measures the impact of trade reform on productivity growth. Results confirm the association between the former and the latter and show that the magnitude of the impact of tariff reduction on the growth rates of TFP and output per worker was substantial. Our data reveal large and widespread productivity improvement, so that the estimations in this paper are an indication that liberalization had an important effect on industrial performance in the country. Cross-sectional differences in protection are also investigated.

The evolution of international output differences (1960-2000): From factors to productivity

This article presents a group of exercises of level and growth decomposition of output per worker using cross-country data from 1960 to 2000. It is shown that at least until 1975 factors of production (capital and education) were the main source of output dispersion across economies and that productivity variance was considerably smaller than in late years. Only after this date the prominence of productivity started to show up in the data, as the majority of the literature has found. The growth decomposition exercises showed that the reversal of relative importance of productivity vis-a-vis factors is explained by the very good (bad) performance of productivity of fast (slow) growing economies. Although growth in the period, on average, is mostly due to factors accumulation, its variance is explained by productivity.

Trade barriers and productivity growth: cross-industry evidence

This article investigates the impact of trade protection on the evolution of labor productivity and total factor productivity (TFP) of the Brazilian manufacturing sector. An annual panel-dataset of 16 industries for the years 1985 through 1997, a period that includes a major trade liberalization, was used. The regressions reported here are robust to openness indicator (nominal tari®s and e®ective protection rate were used), control variables and time period and suggest that barriers to trade negatively a®ects productivity growth at industry level: those sectors with lower barriers experienced higher growth. We were also able to link the observed increase of industry productivity growth after 1991 to the widespread reduction on exective protection experienced in the country in the nineties.

Gains from trade and measured total factor productivity

We develop and calibrate a model where diferences in factor en-dowments lead countries to trade di¤erent goods, so that the existence of international trade changes the sectorial composition of output from one country to another. Gains from trade re ect in total factor productivity. We perform a development decomposition, to assess the impact of trade and barriers to trade on measured TFP. In our sample, the median size of that e¤ect is about 6.5% of output, with a median of 17% and a maximum of 89%. Also, the model predicts that changes in the terms of trade cause a change of productivity, and that efect has an average elasticity of 0.71.

Structural Transformation and Productivity in Latin America

We investigate the role of sectorial differences in labor productivity and the process of structural transformation (reallocation of labor across sectors) in accounting for the time path of aggregate productivity across six Latin American countries (Brazil, Chile, Argentina, Colombia, Mexico and Venezuela) from 1950 to 2003. We used a general equilibrium model with three sectors (agriculture, industry and services) calibrated to those six economies. The model is used to compare the trajectory of productivity in each sector of activity with that of the United States and it impact on aggregate productivity.While in Brazil and Argentina, the Service Sector was responsible for reversing the process of catch up in productivity that occurred until the 1980s, in others, like Colombia, Mexico and Venezuela, low productivity growth of the three sectors explain their poor performance.

As relações acadêmicas de produção na pós-Graduação em administração no Brasil

A presente tese pretende contribuir criticamente para o entendimento das intrincadas relações existentes entre o Estado, o capital e a produção acadêmica. Para isso, se propôs a interpretar as relações acadêmicas de produção na pós-graduação em Administração no Brasil articulando-as com categorias analíticas mais amplas, delineadas de forma a fornecer um quadro, ao fundo, da economia-política. O pressuposto de que a atual intensificação dos ritmos de produção acadêmica contrasta com um passado – idealizado – de ciência contemplativa precisou ser confrontado com o desenvolvimento histórico da educação superior e da pós-graduação no país objetivando-se demover certas mitificações do debate. O Estado, em sua versão reformada a partir do ideário friedmaniano, o conceito de capital monopolista e a teoria do processo de trabalho forneceram suporte teórico-metodológico – e empírico – para a interpretação do quadro político-econômico proposto. Para a passagem do geral para o particular – das conexões entre o Estado e o capital à produção acadêmica – recorreu-se à coleta de dados em duas frentes: (i) analisou-se a produção acadêmica de todos os 168 pesquisadores-doutores bolsistas (até março de 2014) em Produtividade em Pesquisa (PQ) do CNPq na área de Administração e (ii) realizou-se entrevistas em profundidade com pesquisadores-doutores e doutorandos dos mais variados programas de pós-graduação em Administração do país. Os resultados foram inquietantes: verificou-se que está em curso um processo de intensificação da incorporação da mão-de-obra formada por alunos-orientandos às estruturas pedagógico-produtivas dos cursos de pós-graduação. Os orientandos respondem pela parcela mais substantiva do total da produção acadêmica, enquanto que os processos de trabalho aprofundam re-significações das atribuições dos cursos de pós-graduação e intensificam a divisão do trabalho, com impactos diversos nas relações entre os sujeitos da pós-graduação. Quando se procede ao movimento analítico inverso – das relações no interior da pós-graduação em Administração no Brasil para o quadro da economia-política posicionado ao fundo – observa-se que o Estado (principalmente através da CAPES e do CNPq) e o mercado capitalista acadêmico (tendendo a poucas empresas de capital monopolista) acrescentam determinações fundamentais às relações acadêmicas de produção. Índices de avaliação baseados em métricas de contabilidade da pesquisa se legitimam como monopólios epistemológicos da qualidade e se institucionalizam pelas ações coordenadas da CAPES e do CNPq no conjunto do sistema oficial de pós-graduação. Metas de produção são estabelecidas e re-significadas pelos sujeitos. No limite, define-se até mesmo o tipo de ciência que se produz na área. Conclui-se que a resistência aos atuais padrões intensificados de produção acadêmica passa pelo entendimento crítico de todas essas relações que se costuram e se estruturam no interior da pós-graduação.

Collateral, Intermediated Lending, and Aggregate Productivity

Neste trabalho busca-se compreender como que restrições a diferentes tipos de crédito - doméstico e internacional - afetam a dinâmica de uma economia, especialmente com relação a sua Produtividade Total dos Fatores (PTF). Para ajudar no entendimento dessa questão e assuntos relacionados, propomos um simples modelo de economia aberta. Nesse contexto, empreendedores domésticos possuem produtividades heterogêneas, o que implica que a distribuição de riqueza entre indivíduos é essencial para a determinação da produtividade agregada da economia. Além disso, o ambiente de comprometimento limitado obriga os tomadores de empréstimo a dispor de colateral para contrair dívidas. Por hipótese, dívida doméstica e externa requerem diferentes quantidades de colateral. O modelo gera uma dinâmica macroeconômica rica após mudanças na taxa de juros internacional e restrições a crédito. Mais especificamente, um alívio na restrição doméstica causa um aumento da PTF, enquanto a mesma variação na restrição internacional tem o efeito contrário.

Structural transformation and productivity in Latin America

This article examines the e¤ects of sectorial shifts and structural transformation on the recent productivity path of Latin America. We use a four-sector (agriculture, industry, modern services and traditional services) general equilibrium model calibrated to the main economies in the region. The model very closely replicates labor reallocations across sectors and the growth of aggregate labor productivity from 1950 to 2005. Structural transformation explains a sizeable portion of the region s convergence in the rst decades. In most cases, the poor performance of the traditional services sector is the main cause of the slowdown in productivity growth observed in the region after the mid-1970s and is a key factor in explaining the divergence during this period.

Distortions in the investment goods sector and productivity decline

We study the impact of distortions in the investment goods sector on aggregate total factor productivity (TFP). We develop a two-sector neo-classical growth model in which TFP in the capital goods sector relative to TFP in the consumption sector is inversely related to the price of investment relative to consumption, so that we use relative prices to measure TFP in the investment goods sector. The model is calibrated to Brazil and we nd that distortions in the investment goods sector may explain most of the decline in Brazilian TFP relative to the United States since the mid-1970s.

Can unobserved heterogeneity in farmer ability explain the inverse relationship between farm size and productivity?

The well-known inverse relationship between farm-size and productivity is usually explained in terms of diminishing returns with respect to land and other inputs coupled with various types of market frictions that prevent the efficient allocation of land across farms. We show that even if in the absence of diminishing returns one can provide an alternative explanation for this phenomenon using endogenous occupational choice and heterogeneity with respect to farming skills.
