You said you needed a fifty?In a paper titled Toward an Understanding of the Economics of Charity: Evidence from a Field Experiment. This brilliant deduction was discovered.
"This study develops theory and uses a door-to-door fundraising field experiment to explore the economics of charity. We approached nearly 5000 households, randomly divided into four experimental treatments, to shed light on key issues on the demand side of charitable fundraising. Empirical results are in line with our theory: in gross terms, our lottery treatments raised considerably more money than our voluntary contributions treatments. Interestingly, we find that a one standard deviation increase in female solicitor physical attractiveness is similar to that of the lottery incentive."
What does this mean? It means if you are hot, have large breast, or a smokin' ass men tend to give more money away. Next thing they are going to baffle us with is monetary donations increase when males are intoxicated and looking at cleavage or half naked young women. Maybe I can get a research grant for that study? I called this idea, don't you bastards go stealing my stripper money!
