[EX Q]: This man repudiated the Walrasian school after he published a work critical of the marginal productivity theory of distribution. In his magnum opus, he argued that actions are based on illogical decisions called "residues" and are justified by "derivations. " In additio to writing Cours d'economie politique and Mind and Society, his collaborative work with Francis Edgeworth resulted in the indifference curve, and he is also the namesake of a distribution, which leads to the conclusion that 80% of the outcome can be attributed to 20% of the causes. For 10 points, identify this economist, who also names a condition where no person can be made better of without making anybody worse off.

[EX Q]: sum of the squares of the reciprocals of this function evaluated at the nonnegative integers is equal to the modified Bessel function of the first kind at x=2. The Leviathan Number is found by evaluating this function at 10 to the 666th power. The rising type can be represented with the Pochhammer Symbol. Wilson's Theorem states that this function of any prime minus 1 is also congruent to -1 modulo that prime. Legendre's theorem provides a corollary to determine the number of (*) trailing zeroes of this function evaluated at nonnegative integers. When this function is evaluated at large numbers, Stirling's approximation is used. The gamma function extends this function to all complex numbers other than negative integers. For 10 points, name this function that, for positive integers n, is the product from 1 to n, and which is represented by an exclamation point.

[EX Q]: In a 2005 work, Ha Poong Kim argues that its authors hedonistic view of human motivation is integral to the arguments presented in this work. At one point in it, the author bemoans Latins failure to linguistically distinguish between the multiple facets of good and evil. He goes on to state how good and evil cannot be equated with gratification and pain, respectively, because they are a priori principles and how we are freed only through our adherence to the categorical imperative, a view reverse of that previously presented in Groundwork for the Metaphysics of Morals. For 10 points, identify this work of Immanuel Kant, a companion and response to criticism of A Critique of Pure Reason, the second of his three Critiques.
