Understanding Fixed Point Theorems
Arnold, Lutz G. - Wirtschaftswissenschaftliche Fakultät, Universität … - 2003
Fixed point theorems are the standard tool used to prove the existence of equilibria in mathematical economics. This paper shows how to prove a slight generalization of Brouwer's and Kakutani's fixed point theorems using the familiar techniques of drawing and shifting curves in the plane and is,...

Why is the Workplace Racially Segregated by Occupation?
Naqvi, Nadeem - Volkswirtschaftliche Fakultät, … - 2012
by economic theory, but “the hypothesis of employer discrimination does not at all explain segregation by occupation … theory foundations, insofar as they impose a utility indicator function as a primitive concept via persuasion, rather than … to discriminate. Economic theory is, therefore, endogenously color-blind, race-blind, gender-blind, ethnicity-blind, and …

No-arbitrage equilibria with differential information : a proof of existence.
Boisdeffre, Lionel de - Maison des Sciences Économiques, Université Paris 1 … - 2004
On the example of a pure-exchange financial economy with two periods, incomplete nominal asset markets and differential information of the adverse selection's type, Cornet-De Boisdeffre (2002) introduced refined concepts of price, arbitrage and a so-called «no-arbitrage equilibrium», which...

Competitive equilibrium with asymmetric information : an existence theorem for numeraire assets.
Boisdeffre, Lionel de - Maison des Sciences Économiques, Université Paris 1 … - 2005
In a general equilibrium model of incomplete markets with nominal assets and adverse selection, Cornet-De Boisdeffre (3) introduced refined concepts of " no-arbitrage " prices and equilibria, which extended to the asymmetric information. We now present the model with numeraire assets and study...

Irrelevance of private information in two-period economies with more goods than states of nature
Correia-da-Silva, João; Hervés-Beloso, Carlos - In: Economic Theory 55 (2014) 2, pp. 439-455
We introduce a two-period economy with asymmetric information about the state of nature that occurs in the second period. Each agent is endowed with an information structure that describes her (incomplete) ability to prove whether or not a state has occurred. We show that if the number of states...
