This paper estimates the role of agronomic inputs in cereal yield improvements and the consequences for countries' processes of structural change. The results suggest a clear role for fertilizer, modern seeds and water in boosting yields. We then test for respective empirical links between agricultural yields and economic growth, labor share in agriculture and non-agricultural value added per w...

The purpose of this paper is to generate a wider acceptance of emergy analysis a decisionmaking tool in both the public and private sectors. The key to increasing the application of this powerful tool is to link it to productivity. Much of business and public policy decision-making is based on productivity and related efficiency measures. The productivity measures in common use today are narrow...

The advent of modern science made possible the emergence of sustained economic growth. Without growth in scientific knowledge, the productivity growth experienced during the Industrial Revolution would have eventually diminished, as did growth from previous ‘productivity revolutions’ (i.e. agriculture, expansions of trade). Yet scientific knowledge, as distinct from technology or economic produ...

Water use productivity is one of the most important factors in scientific agriculture. It is equal to 0. 7 kg of production per cubic meter of irrigation water (Kg/m3) in Iran which is very low in comparison with advanced countries (1 to 2 Kg/m3). Current research studies temporal and spatialchanges of water use productivity in Hamedan province in Iran using Geographic Information System (GIS),...

in order to study of deficit irrigation levels on wheat grain yield cultivars based on water productivity indices, an experiment was conducted in a split plot arrangement in randomized complete block design at the field of agricultural and natural resources center of isfahan (kabutarabad research station). three levels of irrigations: 60% of full irrigation (f1) and 80% full irrigation (f2) and...

OBJECTIVE To estimate the economic impact likely to be achieved by efforts to vaccinate against 10 vaccine-preventable diseases between 2001 and 2020 in 73 low- and middle-income countries largely supported by Gavi, the Vaccine Alliance. METHODS We used health impact models to estimate the economic impact of achieving forecasted coverages for vaccination against Haemophilus influenzae type b,...

There is a strong theoretical and empirical evidence that Economic growth causes improvements in human development which, in turn, increases economic growth. The improvement in health results in enhancement of basic capabilities that adds value to human life. The transmission to growth takes place through impact on worker productivity, through demography and through trade and investment. Health...

32 Productivity is, once more, on the agenda in many OECD countries. It has long been regarded as the long-run driver of economic growth, but attention for productivity-related issues has waxed and waned over the past decades. In recent years, productivity growth has received a great deal of attention in several OECD countries, notably Australia, Canada, the Netherlands, the United Kingdom and ...

Based on the international community’s analysis of the present CO2 emissions situation, a Log Mean Divisia Index (LMDI) decomposition model is proposed in this paper, aiming to reflect the decomposition of carbon productivity. The model is designed by analyzing the factors that affect carbon productivity. China’s contribution to carbon productivity is analyzed from the dimensions of influencing...
