The effects of external and internal strikes on total factor productivity

This paper examines structural changes that occur in the total factor productivity (TFP) within countries. It is possible that some episodes of high economic growth or economic decline are associated with permanent productivity shocks, therefore, this research has two objectives. The Örst one is to estimate the structural changes present in TFP for a sample of 81 countries between 1950(60) and 2000. The second one is to identify, whenever possible, episodes in the political and economic history of these countries that may account for the structural breaks in question. The results suggest that about 85% of the TFP time-series present at least one structural break, moreover, at least half the structural changes can be attributed to internal factors, such as independence or a newly adopted constitution, and about 30% to external shocks, such as oil shock or shocks in international interest rates. The majority of the estimated breaks are downwards, indicating that after a break the TFP tends to decrease, implying that institutional rearrangements, external shocks, or internal shocks may be costly and from which it is very di¢ cult to recover.

Monetary union and productivity differences in mercosur countries

This paper investigates cross-country productivity convergence among Mercosur members plus associates (Chile and Bolivia) and Peru, during the period 1960-1999. The testing strategy is based on the definitions of time-series convergence by Bernard and Durlauf (1995), and applies sequentially the multivariate unit root tests proposed by Sarno and Taylor (1998), Flôres, Preumont and Szafarz (1995) and Breuer, Mc Nown and Wallace (1999). The last two tests allow to identify the countries that converge. Our results show evidence of convergence among the four Mercosur countries, using either Argentina or Brazil as benchmark. Weaker evidence of convergence is also found with Bolivia. The results point out that monetary union among the Southern Cone economies, though a far objective, is not without sense.

Incompatibilidade distributiva e desenvolvimento auto-sustentado

Effective macroeconomic stability and sustained economic growth will only be achieved in Brazil when the country settles the distributive inconsistency that arose in the 1970s. Since then the state and the nation started to incur respectively in high domestic and foreign debt. Wages grew at much slower rate than productivity, and income concentrated in the hands of business entrepreneurs and particularly of rentiers. Sheer populist practices, or disguised combination of neo-liberal and neopopulist policies were unable to address the problem. Budget deficits and high inflation, or exchange rate overvaluation and financial crises were the typical outcome. To settle distributive inconsistency by compensating in the short term workers for their income losses is not realistic. Only a consistent growth strategy and a credible commitment to share future growth benefits, combined with active social policies oriented to the poor, will do the job.

Productivity of nations: a stochastic frontier approach to TFP decomposition

This Paper Tackles the Problem of Aggregate Tfp Measurement Using Stochastic Frontier Analysis (Sfa). Data From Penn World Table 6.1 are Used to Estimate a World Production Frontier For a Sample of 75 Countries Over a Long Period (1950-2000) Taking Advantage of the Model Offered By Battese and Coelli (1992). We Also Apply the Decomposition of Tfp Suggested By Bauer (1990) and Kumbhakar (2000) to a Smaller Sample of 36 Countries Over the Period 1970-2000 in Order to Evaluate the Effects of Changes in Efficiency (Technical and Allocative), Scale Effects and Technical Change. This Allows Us to Analyze the Role of Productivity and Its Components in Economic Growth of Developed and Developing Nations in Addition to the Importance of Factor Accumulation. Although not Much Explored in the Study of Economic Growth, Frontier Techniques Seem to Be of Particular Interest For That Purpose Since the Separation of Efficiency Effects and Technical Change Has a Direct Interpretation in Terms of the Catch-Up Debate. The Estimated Technical Efficiency Scores Reveal the Efficiency of Nations in the Production of Non Tradable Goods Since the Gdp Series Used is Ppp-Adjusted. We Also Provide a Second Set of Efficiency Scores Corrected in Order to Reveal Efficiency in the Production of Tradable Goods and Rank Them. When Compared to the Rankings of Productivity Indexes Offered By Non-Frontier Studies of Hall and Jones (1996) and Islam (1995) Our Ranking Shows a Somewhat More Intuitive Order of Countries. Rankings of the Technical Change and Scale Effects Components of Tfp Change are Also Very Intuitive. We Also Show That Productivity is Responsible For Virtually All the Differences of Performance Between Developed and Developing Countries in Terms of Rates of Growth of Income Per Worker. More Important, We Find That Changes in Allocative Efficiency Play a Crucial Role in Explaining Differences in the Productivity of Developed and Developing Nations, Even Larger Than the One Played By the Technology Gap

Efeitos dinâmicos de programas de estabilização

Com o emprego do modelo de dois setores de acumulação ótima de capital em economia aberta, determina-se o impacto sobre a trajetória do câmbio, dos salários, do investimento, da poupança e, portanto, da dívida externa e do estoque de capital, de uma elevação permanente e não antecipada da produtividade da economia. Em geral, após um choque positivo permanente de produtividade há redução da poupança, piora do balanço de pagamentos em transações correntes e valorização do câmbio. Todos fenômenos que do ponto de vista do modelo são de equilíbrio intertemporal, conseqüência da elevação da renda permanente e do excesso de demanda por bens domésticos que sucede o ganho de produtividade. Supondo que os programas de estabilização elevaram a produtividade da economia é possível com a estrutura analítica construída racionalizar qualitativamente os fenômenos observados após estes planos.

Infrastructure and productivity in Latin America: is there a relationship in the long run?

This article analyses the relationship between infrastructure and total factor productivity (TFP) in the four major Latin American economies: Argentina, Brazil, Chile and Mexico. We hypothesise that an increase in infrastructure has an indirect effect on long-term economic growth by raising productivity. To assess this theory, we use the traditional Johansen methodology for testing the cointegration between TFP and physical measures of infrastructure stock, such as energy, roads, and telephones. We then apply the Lütkepohl, Saikkonen and Trenkler Test, which considers a possible level shift in the series and has better small sample properties, to the same data set and compare the two tests. The results do not support a robust long-term relationship between the series; we do not find strong evidence that cuts in infrastructure investment in some Latin American countries were the main reason for the fall in TFP during the 1970s and 1980s.

Desenvolvimento econômico e mercado de trabalho urbano no nordeste brasileiro

A história recente do Nordeste caracteriza-se por uma primeira fase de isolamento e outra de articulação. Nessa segunda fase, o dinamismo que se instala a partir da década de sessenta provocou profundas transformações na economia da região. Essas transformações implicaram em elevadas taxas de expansão do produto regional, alterações na estrutura produtiva através da adoção de novos processos de trabalho que implicou de um lado, na redução da demanda por trabalho e de outro, na sua expansão. Registrou-se, também, mudanças bastante significativas nos gêneros industriais reduzindo a participação na produção das indústrias de bens de consumo não-duráveis e aumentando de modo importante a participação das indústrias de bens intermediários voltadas para o mercado nacional e internacional, o que contribui para aumentar a dependência do Nordeste em relação as regiões mais ricas. As mudanças iniciadas no setor industrial se propagam para os setores primários, secundários e terciários. No setor agrícola, as transformações dificultaram a sobrevivência do trabalhador, ampliaram as relações capitalistas no setor manifestas na maior proletarização da mão-de-obra rural; estimularam as emigrações para. as cidades e elevaram consideravelmente a participação da população ocupada em atividades predominantemente urbanas. No setor terciário, as mudanças provocaram o incremento do subemprego, grande diferenciação nos 11 níveis de produtividade e rendimentos, gerando um quadro de aprofundamento da heterogeneidadeda estrutura produtiva e do mercado de trabalho. Adicionalmente, houve uma excessiva urbanização, aumento da concentração da renda, incremento do grau de informalidade, crescimento do número de empregados clandestinos e maior participação dos menores e adultos no mercado de trabalho. Tudo isso, ocorreu,associado ao quadro de dinamismo das atividades produtivas, sem paralelo na história recente das regiões atrasadas do pais. A análise dos dados também mostrou que o nível do desemprego aberto, é relativamente baixo tanto para os homens como para as mulheres. Isto ocorre porque na expansão ou na retração econômica as flutuações no nível de ocupação são acampanhadas por modificações da taxa de participação da PIA no mercado de trabalho. Portanto, a recente infonnalidade, fonnalidade e submersão da mão-de-obra no Nordeste estão associadas a um contexto de crescimento da economia e, por conseguinte, resultam do estilo ou padrão de acumulação de capital que, mesmo se realizando com altas taxas de expansão, não repercute positivamente no mercado de trabalho, nos tennos requeridos pela oferta de mão-de-obra. Assim, o aparecimento de um excedente relativo de população é resultado do padrão de acumulação da capital da economia regional, que está associado ao modo como o Nordeste se inseriu no contexto nacional e, nesse sentido, é o padrão de industrialização o principal fator responsável por parte importante do insucesso da economia local em absorver produtivamente a população que se apresenta no mercado de trabalho urbano

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

Trade in intermediate goods and total factor productivity

We develop and calibrate a model where differences in factor endowments lead countries to trade intermediate goods, and gains from trade reflect in total factor productivity. We perform several output and growth decompositions, to assess the impact that barriers to trade, as well as changes in terms of trade, have on measured TFP. We find that for very poor economies gains from trade are large, in some cases representing a doubling of GDP. Also, that an improvement in the terms of trade - by allowing the use of a better mix of intermediate inputs in the production process - translates into productivity growth.

The evolution of TFP in Latin America: high productivity when distortions were high?

Due to widespread government intervention and import-substitution industrialization, there has been a general presumption that Latin America has been much less productive than the leading economies in the last decades. In this paper, however, we show that until the late seventies Latin America had high total factor productivity (TFP) levels relative to the US and other regions. It is only after the late seventies that we observe a fast decrease of relative TFP in Latin America. Results are robust to the use of diferent methodologies and data sources.

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.
