In mechanism design theory it is common to assume that agents can perfectly report their preferences, even in complex settings which this assumption strains reality. We experimentally test whether real market participants preferences for course schedules “accurately enough” a novel allocation mechanism, approximate competitive equilibrium from equal incomes (A-CEEI), realize its theoretical ben...

This paper develops a new method of estimating rich, dynamic models of health based on multiple health measures available in the HRS. We apply these methods to investigate what generates the large socioeconomic gradient in health. Preliminary results suggest a large role for initial differences in health at age 50 that persist into old age.

We have developed algorithms to count singular values of a bidiagonalmatrix which are greater than a speci ed value This requires the transformation of the singular value problem to an equivalent symmetric eigenvalue problem The counting of sin gular values is paramount in the design of bisection and multisection type algorithms for computing singular values on serial and parallel machines The ...

Numerical reproducibility failures rise in parallel computation because floating-point summation is non-associative. Massively parallel and optimized executions dynamically modify the floating-point operation order. Hence, numerical results may change from one run to another. We propose to ensure reproducibility by extending as far as possible the IEEE-754 correct rounding property to larger op...

PURPOSE To study whether the accommodation response to Badal optometer is equivalent to the response for real space targets. METHODS Accommodative responses were measured for 28 young eyes with the WAM-5500 autorefractometer in eight configurations for 0.17 D, 2.0 D and 5.0 D accommodation stimuli. Parameters that might contribute to differences in response were systematically isolated: stimu...
