Havránek, Tomáš - 2013
I examine 2,735 estimates of the elasticity of intertemporal substitution in consumption (EIS) reported in 169 published studies. The literature shows strong publication bias: researchers report negative and insignificant estimates less often than they should, which pulls the mean estimate up by...
