A global concerns focus on environmental protection and natural resource management. The sustainability of natural resources has taken central stage amongst researchers, the public and policy makers as a key issue in global change and biodiversity preservation. Need has risen to develop an understanding of microbial diversity responsible for variable reaction in different soil orders. There is ...

I develop a quantitative, dynamic general equilibrium model of life cycle behavior to study the effects of several policy reforms on assets composition over the life cycle, wealth distribution and aggregate saving. Privatizing social security increases aggregate saving, decreases overall wealth inequality, and generates large welfare gain, especially for agents with high initial productivity. L...

This paper provides new evidence that estimates obtained from aggregated data may not provide reliable estimates of average firm-level parameters, if the composition of producers with different levels of productivity changes over the business cycle. I examine plant-level data and show that, due to the countercyclical reallocation of output among heterogenous plants, productivity measures based ...

Acknowledged by most researchers and scholars, human resource productivity is the most important factor in the resistive economy and business. On the other hand, Workforce diversity is one of the major challenges of this century; and perhaps for managers, managing diversity is more important than seeking diversity to maximize the human resource productivity. The present study aims to analyze th...

Hedgerows are as dynamic the plants that make them, which means it would be fighting a losing battle if we tried to keep them same size and shape forever. Instead, work out where hedge is on management cycle according that. The ultimate goal in create thick, dense hedgerow. These hedges most beneficial landowners well for nature. When cut at point year after year, will produce fewer flowers fru...
