This paper shows in an experiment that giving rates in a dictator game increase significantly if payments are offered with delay. We hypothesize that a temptation to be selfish may be at play in social preferences. We model this and demonstrate that our model is consistent with much of the...

It has been argued that estimating the spectral density function of a stationary stochastic process at the zero frequency (or the so-called long-run variance) is an ill-posed problem so that any estimate will have an infinite minimax risk (e.g., Pötscher 2002). Most often it is a nuisance...
