Subjective Expected Utility with Non-Increasing Risk Aversion
It is shown that assumptions about risk aversion, usually studied under the pre-supposition of expected utility maximization, have a surprising extra merit at an earlier stage of the measurement work: together with the sure-thing principle, these assumptions imply subjective expected utility maximization for monotonic continuous weak orders
On the relaxation of integral functionals depending on the symmetrized gradient
We prove results on the relaxation and weak* lower semicontinuity of integral
functionals of the form
over the space of functions of bounded deformation or
over the Temam-Strang space
depending on the growth and shape of the integrand . Such functionals are
interesting for example in the study of Hencky plasticity and related models.Comment: 30 page
Least Concave Ordinal Utility Function and the Marshalian Cardinal Utility
This paper examines the conditions under which the Marshallian type of cardinal utility function can be derived from a class of ordinal utility functions

Learning Theory and Algorithms for Revenue Optimization in Second-Price Auctions with Reserve
Second-price auctions with reserve play a critical role for modern search
engine and popular online sites since the revenue of these companies often
directly de- pends on the outcome of such auctions. The choice of the reserve
price is the main mechanism through which the auction revenue can be influenced
in these electronic markets. We cast the problem of selecting the reserve price
to optimize revenue as a learning problem and present a full theoretical
analysis dealing with the complex properties of the corresponding loss
function. We further give novel algorithms for solving this problem and report
the results of several experiments in both synthetic and real data
demonstrating their effectiveness.Comment: Accepted at ICML 201
