the environmental degradation increase during recent years, has proposed the investigation of economic activities and environmental indicators relation. mostly a unidirectional causality from economic activities to pollution is assumed. while the direction of causality between pollution and economic growth has specific policy implications, presumption of this direction may influence the nature ...

The significant reduction in agricultural production Sri Lanka, compounded by the rising prices of fuel and basin food items followed shortages Afghanistan increase consumption worldwide carry our global concern towards security sustainability mere self-sufficient production. Agriculture is extremely vulnerable to climate change. Extreme happens like heavy rainfall, high temperature drought mak...

Phospholipid-coatings on metallic implant surfaces were evaluated in terms of adhesion, proliferation and matrix production of skeletal cells, and of macrophage stimulation. The working hypothesis is that mimicking a model biomembrane by phospholipids on surfaces to which cells adhere, the surface recognition by surrounding cells is altered. In this study, 1) mirror-like polished Ti-6Al-7Nb and...

Improving “ last-mile” public service delivery is a recurring challenge in developing countries. Could the widespread adoption of mobile phones provide scalable, cost-effective means for improvement? We use large-scale experiment to evaluate impact phone-based monitoring on program that transferred nearly billion dollars 5.7 million Indian farmers. In randomly selected jurisdictions, officials ...

this article examines the basic assumption of rational expectations hypothesis on iran's economy from 1966 to 2003. this assumption suggests the neutrality or ineffectiveness of money policy on the development of real variables of production and employment. the results from estimation of production equation do not support the significant influence of unanticipated component of money growth...

This study applies a production function approach to value the groundwater recharge function of the Hadejia-Nguru wetlands in northern Nigeria. The groundwater recharge function supports dry season agricultural production which is dependent on groundwater abstraction for irrigation. Using survey data this paper first carries out an economic valuation of agricultural production, per hectare of i...

To what degree can labor reallocation mitigate the economic consequences of weather-driven agricultural productivity shocks? I estimate that temperature-driven reductions in demand for India are associated with increases nonagricultural employment. This suggests ability sectors to absorb workers may play a key role attenuating shocks. Exploiting firm-level variation propensity workers, relative...
