Abstract: [eng] SUMMARY August 194& the fare on the Paris underground railway was substan tially increased for the buyer- of one ticket at time but no change was made in the price of the book of five ticket;- perfect example of pure economie discrimination aud differential demand was thus afforded iu making the same transportation service available ro everybody at two different prices Sales of tickets one by ue showed au immediate sharp decime while the ticker book maintained irs average sales level despite the downward trend of underground traffic The above response clearly indicates that the concept of the economic man acring in his self-interest which again has been undergoing heavy criticism still has validity and should not be too lightly dismissed either in economic theory or iu the making of economic decisions
