Dynamics of Labor Demand: Evidence from Plant-level Observations and Aggregate Implications [PDF]

open access: yes
This paper studies the dynamics of labor demand at the plant and aggregate levels. The correlation of hours and employment growth is negative at the plant level and positive in aggregate time series. Further, hours and employment growth are about equally

Plant responses to plant growth-promoting rhizobacteria [PDF]

open access: yesEuropean Journal of Plant Pathology, 2007
Non-pathogenic soilborne microorganisms can promote plant growth, as well as suppress diseases. Plant growth promotion is taken to result from improved nutrient acquisition or hormonal stimulation. Disease suppression can occur through microbial antagonism or induction of resistance in the plant. Several rhizobacterial strains have been shown to act as
