Abraham Wald, 1902-1950 Born in Cluj, Transylvania (now Romania, then part of Hungary) in 1902. In 1927, he enrolled in the mathematics department of the University of Vienna, receiving his PhD in 1931. He was one of Karl Menger's students and was quickly introduced to the Viennese banker and economist Karl Schlesinger who, in turn, introduced him to the problems of the sytem of Walras and Cassel being dealt with at the time by the Vienna Colloquium Wald wrote three papers (1935, 1936a,b) on the Walras-Cassel system, employing the important "Duality Principle" and complementary slackness conditions which he (together with Schlesinger ) developed for the Walras-Cassel G.E. system - which did away with the counting-equations- and-unknowns method, but allowed the return of Wieser's imputation theory back into economics and the employment of linear programming. Wald's third paper was particularly important and contributed several factors besides linear programming. Wald's paper was also the first proof of the existence of an equilibrium in a G.E. setting in economics. It also introduced several important concepts: the weak axiom of revealed preference (WARP) - later employed and developed by Paul Samuelson . He also addressed (briefly) the issue of whether it would hold in the aggregate (a question ignored and unanswered until the mid-1970s). He also defined a primitive form of the idea of "gross substitution" and provided a proof of the uniqueness of equilibrium. He also used these tools to tackle the existence of an equilibrium in a

Abraham Wald Born: Died: 13 Dec 1950 in Travancore, India Click the picture above to see four larger pictures Show birthplace location Previous (Chronologically) Next Biographies Index Previous (Alphabetically) Next Main index Version for printing Abraham Wald was born into a Jewish family in Hungary. It was a family of intellectuals but, being Jewish, they were forced to earn their living in trades well below their abilities. At this time both primary and secondary schools in Hungary required pupils to attend on Saturdays and the Wald family could not allow their son to attend school on the Jewish Sabbath. As a result Abraham did not attend either primary of secondary school and was educated at home by members of his family. This certainly did not put him at a disadvantage from an educational point of view for his family were very knowledgeable and competent teachers. After World War I much of the land that had been part of Hungary was given to neighbouring countries and at that time Cluj became part of Romania. Wald was allowed to attend the University of Cluj but it appears that this was not made easy for him because he was Jewish. However his outstanding abilities in mathematics led him to wish to continue to undertake mathematical research and in 1927 he entered the University of Vienna to study with Karl Menger . He worked under Menger 's supervision on geometry and was awarded his doctorate in 1931.

14. The Wald System It was up to abraham wald (1935, 1936) to show that this was not necessary and Now we turn to the existence question posed by abraham wald (1935, 1936). http://cepa.newschool.edu/het/essays/get/waldsys.htm

The Wald System "Accordingly, to a follower of Menger, the determination of economic equilibrium would not merely involve the determination of the prices of those goods which have prices (as in Walras); it should also involve the determination of which goods are to have prices and which are to be free. The weakness of the Walras-Cassel lies in the implied assumption that the whole amount of each available factor is utilized; once that assumption is dropped, the awkwardness of the construction....can be shown to disappear." (John Hicks , "Linear Theory", Economic Journal Contents Problems in the Walras-Cassel Model The Schlesinger-Wald Inequalities and Shadow Values A Simple Graphical Illustration Existence and Uniqueness of Equilibrium ...

Problems in the Walras-Cassel Model Recall that in the simplest Walras-Cassel system we had the following set of equations: (i) Output market equilibrium: x D p w (ii) Factor market equilibrium: v B x (iii) Price-cost equalities: p Bw If we have n produced goods and m factors, then have n equations in (i), m equations in (ii) and n equations in (iii), but as we can always remove one equation by Walras's Law, then we have a total of 2n+m-1 equations. The unknowns in this system are

Abraham: Old and New Old Father Abraham Abraham is revered by Jews, Christians, and Muslims alike, most fundamentally because he freed us from the irreparable error and irredeemable horror of religious child sacrifice. The ancient story of God's angel liberating Abraham from his religious compulsion to kill his son, Isaac, marks the long-awaited turning point in the obviously sincere but tragically mistaken human belief that God wants us to kill our children as a sacrifice to Him (Genesis 22). After God's angel freed Abraham and Isaac, Abraham in turn freed his people from their fear-driven religious compulsion to sacrifice their own innocent children. Just as Abraham had received Isaac back alive and well through God's saving angel, so Abraham gave his people back their own living children from their earlier lethal misunderstanding of God. Through his courageous example, Abraham proved to them that God is far more just, kind and loving than they, until then firmly in the grip of their deadly fundamentalist religious terror, ever had dared even to hope. They had been blinded by their fear of God, but Father Abraham helped them see God more clearly. As a result, their babies, our ancestors - spiritual, and for some, physical - lived. No wonder we Jewish, Christian, and Muslim parents revere our common Father Abraham so deeply. He saved us and our children for all time from our old, imaginary, terrifying, child-killing god. We owe God's angel and Father Abraham our very lives, our children's, our grandchildren's, ...
