| Resumo: Procedimentos de avaliação de impactos têm sido realizados para analisar e promover estratégias de integração lavoura-pecuária-floresta (ILPF) adotadas em Unidades de Referência Tecnológica (URTs) no âmbito da ?Rede de Fomento ILPF?. A abordagem, baseada no método multicritério Ambitec-Agro, foi realizada em seis URTs em colaboração com equipes da Embrapa e parceiros em todo o país. Estes estudos de caso incluíram desde empresas rurais de grande porte até estabelecimentos familiares, e desde complexos esquemas de integração até simples integração lavoura-pecuária voltada apenas à reforma de pastagens. Devido ao seu típico efeito de intensificação, a ILPF resultou em importantes ganhos de produtividade e de eficiência no uso de recursos naturais,... |

| This paper explores the economics of land degradation in the rice-shrimp system in the Mekong Delta of Vietnam. A bioeconomic NPV model was developed to evaluate and compare the long-term benefits of alternative production choices and farm technologies. There is an alternative rice-shrimp technology emerging in Vietnam that does not have the same land degrading impacts as the 'traditional' system, however the high capital outlay and risk associated with such technology presents its own problems. In the paper the economic incentives for adoption of the non-land degrading rice-shrimp technology are explored. Conclusions are drawn with regard to the opportunity cost of land degradation and technological change. Some conclusions are also provided on the policy... |

| The article analyses the effect of trade liberalization, of final consumption and of technological change on employment structure of Brazil and sector agro cattle raising, by skill level, between 1985 and 2003. Therefore, were used input-output and PNAD data of respective years. The results obtained show important change on the employment structure of sector agro cattle raising in this period, in favor the skilled workers, yet that in less proportion relative to others economic sectors, caused by technological change and trade foreign. The agro cattle raising sector revealed dynamic in its employment structure, benefiting more the skill labor with raised labor productivity |

| Labor productivity in U.S. coal mining increased at an average annual rate of slightly over four percent during the past 45 years. This report examines key factors contributing to that record - particularly, technological innovation in both surface and underground mining and concurrent geographic shifts in U.S. coal production. Health, safety, and environmental regulations introduced in the sixties and seventies, as well as labor unrest, interrupted long-term productivity advance; but the interruption was of limited duration. Although our principal focus is on worker productivity, steady growth in the relative importance of nonlabor inputs underscores the need to consider total factor productivity. The report touches on the productivity record using that... |

| German wind power development is a technological success story but has involved very high subsidies. Germany was a latecomer in wind power but specific political conditions in the late 1980s and early 1990s allowed the implementation of the feed in tariff regime which has characterised Germany ever since. The wind lobby managed to constitute itself at an early stage and to develop stable alliances with farmers and regional policymakers. The concentration of the wind industry in structurally weak regions reinforced these links. With an increased visibility of the subsidies and saturation of onshore sites in the early 2000s, the lobby has been less successful in retaining support. The current attempt to develop offshore projects may suffer from less... |

| We develop a methodology for testing Hick's induced innovation hypothesis by estimating a product-characteristics model of energy-using consumer durables, augmenting the hypothesis to allow for the influence of government regulations. For the products we explored, the evidence suggests: (i) the rate of overall innovation was independent of energy prices and regulations, (ii) the direction of innovation was responsive to energy price changes for some products but not for others, (iii) energy price changes induced changes in the subset of technically feasible models that were offered for sale, (iv) this responsiveness increased substantially during the period after energy-efficiency product labeling was required, and (v) nonetheless, a sizeable portion of... |

| A growth accounting and an econometric exercise are used to provide insights into the evolution of the Taiwanese economy over the period 1966-96. The approach links the GDP function of a multiple sector neoclassical growth model to growth accounting and, subsequently to the estimation of the parameters of this function. The growth accounting results show that the contribution of total factor productivity (TFP) to growth in GDP averaged about 32 percent over the period, and this contribution increased as the economy approached its long-run equilibrium during the decade of the 1980s, with evidence of some departure during 1991-96. Growth in TFP increased output growth in industry and services while growth in skilled labor benefited all sectors. Growth in... |
