Do State Laws Protecting Older Workers from Discrimination Reduce Age Discrimination in Hiring? Evidence from a Field Experiment.

The Journal of law & economics

Neumark D, Burn I, Button P, Chehras N.
PMID: 32051647
J Law Econ. 2019 May;62(2):373-402. doi: 10.1086/704008.

We conduct a resume field experiment in all U.S. states to study how state laws protecting older workers from age discrimination affect age discrimination in hiring for retail sales jobs. We relate the difference in callback rates between old...

The Mediterranean climate is characterized by hot dry summers and frequent droughts. Mediterranean crops are frequently subjected to high evapotranspiration demands, soil water deficits, high temperatures, and photo-oxidative stress. These conditions will become more severe due to global warming...

Effectiveness of glatiramer acetate in neutralizing antibody-positive patients previously treated with interferon-β.

Multiple sclerosis and related disorders

Buron MD, Magyari M, Chalmer TA, Sørensen PS, Sellebjerg F.
