This paper is concerned with learning decision-makers’ preferences using data on observed choices from a finite set of risky alternatives. We propose discrete choice model unobserved heterogeneity in consideration sets and standard risk aversion. obtain sufficient conditions for the model’s semi-nonparametric point identification, including cases where depends some exogenous variables. Our meth...

Sutton (1998) has recently proposed a theoretical lower bound to firm size inequality when a market is made of several independent submarkets. His results are valid asymptotically, as the number of submarkets becomes arbitrarily large. We show that, in small samples, his results can be interpreted as a positive relationship between an index of firm size inequality and the number of submarkets. ...

Affective decision-making (ADM) is a refutable and predictive theory of individual choice under risk and uncertainty. It generalizes expected utility theory by positing the existence of two cognitive processes – the “rational” and the “emotional” process. Observed choice is the result of their simultaneous interaction. We present a model of affective choice in insurance markets, where risk perc...

The thermodynamics and kinetics for base-pair opening of the P1 duplex of the Tetrahymena group I ribozyme were studied by NMR hydrogen exchange experiments. The apparent equilibrium constants for base pair opening were measured for most of the imino protons in the P1 duplex using the base catalysts NH3, HPO4(2-) or TRIS. These equilibrium constants were also measured for several modified P1 du...

The G- and U-specific reagent, carbodiimide was used to probe the solution structure of aminoacylated yeast phenylalanine tRNA. Both quantitative and qualitative changes in modification were observed when the modification patterns of tRNA-CCA(3'OH), tRNA-CCA(3'NH2) and phe-tRNA-CCA(3'NH2) were compared. Five nucleotides were modified in all cases, D16 and G20 in the D-loop, U33 and Gm34 in the ...

Minor groove binding compounds related to distamycin A bind DNA with high sequence selectivity, recognizing sites which contain various combinations of A.T and G.C base pairs. These molecules have the potential to deliver cross-linking agents to the minor groove of a target DNA sequence. We have studied the covalent DNA-DNA cross-linked complex of 2,3- bis(hydroxymethyl)pyrrole-distamycin and [...

In these notes we compute the geodesic curvature on a surface in isothermal coordinates and use it to prove the local Gauß-Bonnet Theorem. These remarks are a continuation of my notes [T] whose notation we continue to employ. 1. Isothermal Coordinates of a Surface. The computations are facilitated by using a special coordinate system in which the metric and the resulting formulas take a particu...

A parallel algorithm for the enumeration of isolated connected clusters on a regular lattice is presented. The algorithm has been implemented on 17 RISCbased workstations to calculate the perimeter polynomials for the plane triangular lattice up to clustersize s = 21. New data for perimeter polynomials D s up to D21, total number of clusters gs up to g22, and coefficients b~ in the low-density ...

A popular solution to the looming entitlements crisis in the United States is to increase the eligibility age for Medicare. Using an empirical model of insurance choice with endogenous prices, I find that this would have a modest welfare cost. The losses are concentrated among those who lose Medicare coverage. For the non-elderly, the benefit of lower taxes is mitigated by a higher price for me...
